The quick connection structure 10 includes a first component 100, a second component 200, a locking component 300, and a first reset component 400. In this embodiment, the first component 100 is a movable component for supporting a camera, and the second component 200 is a fixed component for connecting a Pan-Tilt which is generally mounted on a tripod. A screw may be connected to the first component 100 with an end thereof extending upwardly for quick connection of the camera, and a screw hole or a dovetail groove may be defined in the second component 200 for quick connection of the Pan-Tilt. The assembly and disassembly of the first component 100 and the second component 200 realizes the assembly and disassembly of the camera and the tripod. In other embodiments, the first component 100 may be connected to the tripod, and the second component 200 may be connected to the camera, which will not be described here.
The second component 200 includes a mounting portion 210 defining a mounting groove 211 therein for receiving the first component 100, and a first locking portion 290 movably connected to the mounting portion 210 for locking the first component 100. The mounting groove 211 extends along a central axis 241 of the mounting portion 210, and the first component 100 can be inserted axially into the mounting groove 211. A top end of the mounting groove 211 functions as an entrance 2111, for entering of the first component 100 into the mounting groove. When the first locking portion 290 is at a locking position, the first component 100 which is inserted into the mounting groove 211 can be locked; and when the first locking portion 290 is at an unlocking position, the first component 100 in the mounting groove 211 can be unlocked and then removed. When the first component 100 is inserted into a predetermined position of the mounting groove 211 and the first locking portion 290 is at the locking position, the first component 100 can be locked, thereby completing the connection of the first component 100 and the second component 200, realizing the quick assembly of the camera and the tripod.
The locking component 300 is movably connected to the mounting portion 210, and is capable of moving relative to the mounting portion 210 to a first position or a second position. That is, the locking component 300 is capable of moving back and forth between the first position and the second position. Moving of the locking component 300 to the first position and the second position described in this application both are relative to the mounting portion 210. The locking component 300 may slide to the first position or the second position along a straight line or a curve, or may rotate to the first position or the second position. In this embodiment, the locking component 300 slides to the first position or the second position along a straight line. The locking component 300 is configured to drive the first locking portion 290 to the locking position during the sliding motion thereof to the first position, and enable the first locking portion 290 to return to the unlocking position when moving to the second position.
When the first component 100 is inserted into the predetermined position of the mounting groove 211, the locking component 300 is capable of driving the first locking portion 290 to move from the unlocking position to the locking position after the locking component 300 moves from the second position to the first position, thereby realizing the locking of the first component 100. After the locking component 300 moves from the first position to the second position, the first locking portion 290 is capable of moving to the unlocking position, thereby enabling the first component 100 to be separated from the mounting portion 210. It should be noted that the locking component 300 may drive the first locking portion 290 directly or indirectly, i.e., through other components. In this embodiment, the locking component 300 drives the first locking portion 290 directly. After the locking component 300 moves to the second position, the first locking portion 290 may return to the unlocking position automatically, for example by gravity. Alternatively, the first locking portion 290 may return to the unlocking position under an action of an elastic member or a magnetic member; or, return to the unlocking position by a propulsive force applied thereon when the first component 100 exiting from the mounting groove 211.
In summary, in this embodiment, when the locking component 300 at the first position, the first component 100 can be connected the second component 200; and when the locking component 300 at the second position, the first component 100 and the second component 200 can be separated from each other.
The first reset component 400 is connected to the locking component 300 and the mounting portion 210, respectively, and generates a force to drive the locking component 300 to move to the first position. In this embodiment, the locking component 300 can be designed to stay at the first position at an initial state. When the first reset component 400 is not pushed to slide relative to the mounting portion 210 by the operator, the first reset component 400 is capable of pushing the locking component 300 to stay at the first position. The first reset component 400 may be a spring, a magnetic member, and etc. In this embodiment, the first reset component 400 is a spring.
In that case where the quick connection structure only has the above-mentioned constructions, the first component 100 cannot be inserted into the predetermined position of the mounting groove 211 since the locking component 300 at the first position and the first locking portion 290 at the locking position. When the first component 100 needs to be assembled onto the second component 200, the locking component 300 needs to be held by one hand of the operator to make it stay at the second position, so that the first component 100 can be inserted into the predetermined position of the mounting groove 211. After the first component 100 is inserted into the predetermined position of the mounting groove 211 by the other hand of the operator to unlock the locking component 300, the hand holding the locking component 300 can be removed, and thus the first reset component 400 is capable of pushing the locking component 300 to move back to the first position, thereby completing the locking of the first component 100. During the above assembly process, the operator needs to operate with two hands, and the hand holding the locking component 300 needs to apply force continuously, which is inconvenient.
In view of this, in this embodiment, the second component 200 further includes a second locking portion 270 and an unlocking portion 281. The second locking portion 270 is configured to lock the locking component 300 at the second position. The unlocking portion 281 is configured to drive the second locking portion 270 to release the locking component 300 after obtaining a driving force, which is given to the unlocking portion 281 during the inserting of the first component 100 into the mounting groove 211. In other words, after the locking component 300 slides to the second position by the operator, the second locking portion 270 locks the locking component 300 at the second position, thus the operator does not need to continuously apply force to the locking component 300. During the inserting of the first component 100 into the mounting groove 211, the unlocking portion 281 can be driven to move, which in turn drives the second locking portion 270 to unlock the locking component 300, thereby the locking component 300 being able to return to the first position under the driving force of the first reset component 400, and then making the first locking portion 290 lock the first the member 100.
In this embodiment, during the assembly of the first component 100 and the second component 200 of the present quick connection structure 10, firstly the locking component 300 slides relative to the second component 200 by one hand of the operator to the second position, where the locking component 300 can be locked by the second locking portion 270 and the hand of the operator holding the locking component 300 can be removed; and then, the first locking portion 290 moves to the unlocking position, which makes the first component 100 can be inserted into the mounting groove 211 by one hand. During the inserting of the first component 100 into the mounting groove 211, the unlocking portion 281 is driven to make the second locking portion 270 unlock the locking component 300, thereby the locking component 300 being capable of moving back to the first position, and then making the first component 100 be locked by the first locking portion 290. The whole assembly process described above can be completed by a single hand of the operator, which is convenient and fast.
The specific construction of the first locking portion 290 to lock the first component 100 may be designed according to need. In this embodiment, the mounting portion 210 includes an annular wall 240 which surrounds the central axis 241. The mounting groove 211 is defined in the annular wall 240 and extends along the central axis 241. As shown in
The quick connection structure 10 further includes a second reset component 251, which is connected to the mounting portion 210 and the first locking portion 290, respectively. The second reset component 251 generates a driving force to make the first locking portion 290 move to the unlocking position. That is, after the locking component 300 slides to the second position, the second reset component 251 is able to drive the first locking portion 290 to the unlocking position where the first locking portion 290 exits out of the annular wall 240 to realize locking of the first component 100.
The locking component 300 is arranged at an outer side of the annular wall 240 along the radial direction, i.e., a side of the annular wall 240 away from the central axis 241. The locking component 300 slides axially and straightly. During the movement of the locking component 300 to the first position, the first locking portion 290 is pushed to move towards the central axis 241 to the locking position. During the sliding motion of the locking component 300 to the first position, the locking component 300 is capable of pushing the first locking portion 290 to move radially (i.e., along a direction perpendicular to the central axis 241) and inwardly to the locking position.
The locking component 300 is annular, and is mounted around the annular wall 240. The locking component 300 is configured to be slidable with respect to the mounting portion 210 along a direction parallel to the central axis 241. The locking component 300 may slide upwardly (i.e., along a direction towards the entrance 2111 of the mounting groove 211) to the first position or slide downwardly (i.e., along a direction away from the entrance 2111 of the mounting groove 211) to the second position. In this embodiment, the locking component 300 may push the first locking portion 290 through an inner circumferential surface 310 thereof.
The first reset component 400 is arranged between the locking component 300 and the annular wall 240. The first reset component 400 is a spring, which is mounted around the annular wall 240. An end of the spring away from the entrance 2111 abuts against the mounting portion 210, and an end of the spring near the entrance 2111 abuts against the locking component 300.
As shown in
The quick connection structure 10 further includes a third reset component 252, which may be a spring in an embodiment. The third reset component 252 is mounted in the second mounting hole 230, and can generate a driving force to make the second locking portion 270 extend out of the annular wall 240 to lock the locking component at the second position 300. During the movement of the locking component 300 to the second position, the second locking portion 270 is pushed to slide radially towards the central axis 241. After the locking component 300 moves to the second position, the third reset component 252 drives the second locking portion 270 to slide radially away from the central axis 241, thereby making the second locking portion 270 lock the locking component 300.
The inner circumferential surface 310 of the locking component 300 is provided with an annular protrusion 320 which is arranged around the central axis 241. The annular protrusion 320 includes a first annular wall 322 and a first inclined wall 321. The first annular wall 322 and the first inclined wall 321 are arranged opposite to each other along the axial direction. The first annular wall 322 faces to the entrance 2111, and the first inclined wall 321 is away from the entrance 2111. During the movement of the locking component 300 from the first position to the second position, the first inclined wall 321 pushes the second locking portion 270 to slide radially towards the central axis 241; and, the second locking portion 270 is pushed by the third reset component 252 to abut against the first annular wall 322 after the annular protrusion 320 slides over the second locking portion 270, thereby the second locking portion 270 locking the locking component 300.
The inner circumferential surface 310 of the locking component 300 includes a second inclined wall 330 which is arranged around the central axis 241. The second inclined wall 330 is located at a side of the annular protrusion 320 near the entrance 2111. The second inclined wall 330 is configured to push the first locking portion 290 to extend out of the annular wall 240 when the locking component 300 slides from the second position to the first position, thereby pushing the first locking portion 290 to the locking position.
An unlocking component 280 is mounted in the mounting groove 211, and is located at an end of the mounting groove 211 away from the entrance 2111. The unlocking component 280 is configured to push the second locking portion 270 to move radially towards the central axis 241 when it moves away from the entrance 2111.
The quick connection structure 10 further includes a fourth reset component 253, which is connected to the mounting portion 210 and the unlocking component 280, respectively. The fourth reset component 253 is configured to generate a driving force to make the unlocking component 280 move towards the entrance 2111.
The unlocking component 280 includes the unlocking portion 281, which can extend into the second mounting hole 230. As shown
The assembly process of the quick connection structure 10 of this embodiment is as follows:
The operator pushes the locking component 300 from the first position (a position near the entrance 2111 of the mounting groove 211) to the second position along the axial direction away from the entrance 2111 of the mounting groove 211, the first locking portion 290 returns to the unlocking position, i.e., a position that the first locking portion 290 extends out of the annular wall 240 of the mounting portion 210 from the locking position under the driving force of the second reset component 251 during the sliding motion of the locking component 300 to the second position, which makes the first component 100 can be inserted into the predetermined position of the mounting groove 211. During the sliding motion of the locking component 300 to the second position, under the cooperation of the annular protrusion 320 and the second locking portion 270, firstly the second locking portion 270 is pushed by the locking component 300 to move radially towards the central axis 241, and then the second locking portion 270 moves radially away from the central axis 241 to lock the locking component 300 after the locking component 300 reaching the second position, thereby making the locking component 300 stay at the second position.
The operator inserts the first component 100 into the mounting groove 211 to press the unlocking component 280 downwardly, the inserting of the first component 100 pushes the unlocking component 280 to move away from the entrance 2111 of the mounting groove 211. Under the cooperation of the unlocking portion 281 and the second locking portion 270, the unlocking portion 281 pushes the second locking portion 270 to move radially towards the central axis 241 to a position where the locking component 300 can be unlocked. After the first component 100 is inserted into the predetermined position of the mounting groove 211 and the locking component 300 is unlocked, the first reset component 400 pushes the locking component 300 to move back to the first position, and the first locking portion 290 is pushed to move to the locking position to lock the first component 100 during the movement of the locking component 300 to the first position, thereby completing the locking of the first component 100.
Referring to
The second component 200 includes a mounting portion 210, and the mounting portion 210 includes an annular wall 240 arranged around the central axis 241. The mounting portion 210 defines a mounting groove 211 therein, the mounting groove 211 extends along the central axis 241. The mounting portion 210 defines a first mounting hole 220 which extends through the annular wall 240 radially, i.e., along a direction perpendicular to the central axis 241. The second component 200 further includes a first locking portion 290 movably mounted in the first mounting hole 220. When the first locking portion 290 slides to the locking position, i.e., extends into the mounting groove 211, the first component 100 inserted into the mounting groove 211 can be locked. When the first locking portion 290 slides to the unlocking position, i.e., withdrawn from the mounting groove 211, the first component 100 can be unlocked.
The locking component 300 is movably connected to the mounting portion 210, and may rotate relative to the mounting portion 210 about the central axis 241 to the first position or the second position. The locking component 300 is configured to drive the first locking portion 290 to the locking position during the rotation thereof to the first position, and enable the first locking portion 290 to return to the unlocking position when it rotates to the second position.

The second component 200 further includes a second locking portion 270 and an unlocking portion 281. The second locking portion 270 is configured to lock the locking component 300 at the second position. The unlocking portion 281 is configured to drive the second locking portion 270 to release the locking component 300 after obtaining a driving force, which is given to the unlocking portion 281 during the inserting of the first component 100 into the mounting groove 211. The difference between this embodiment and the first embodiment is that: the locking component 300 of this embodiment is rotatable relative to the mounting portion 210 for realizing locking of the first component 100. The quick connection structure 10 of this embodiment also has the technical effect of facilitating the assembly and disassembly.
The locking component 300 is annular, and is mounted around the second component 200. The locking component 300 includes an inner circumferential surface 310 arranged around the central axis 241, and the inner circumferential surface 310 includes an arc-shaped wall 340 arranged around the central axis 241. Along a circumferential direction of the locking component 300, a radial distance between the arc-shaped wall 340 and the central axis 241 increases gradually. During the rotation of the locking component 300 relative to the mounting portion 210 along the circumferential direction, the arc-shaped wall 340 can push the first locking portion 290 to move from the unlocking position to the locking position.

The first mounting hole 220 includes a first hole portion 221 and a second hole portion 222, the second hole portion 222 is at an inner side of the first hole portion 221 along the radial direction and communicates with the mounting groove 221. An area of a cross section of the first hole portion 221 is larger than that of the second hole portion 222, and a step 223 is formed at a junction of the second hole portion 222 and the first hole portion 221.
The quick connection structure 10 further includes a second reset component 251, the first locking portion 290 includes a contact part facing the step 223, and the second reset component 251 is arranged between the contact part and the step 223 with one end thereof connected to the step 223 and the other end thereof connected to the contact part. The second reset component 251 generates a force to drive the first locking portion 290 move to the unlocking position. The force of the first reset component 400 is greater than that of the second reset component 251. Thus, after the locking component 300 is pushed to move to the first position by the first reset component 400, the second reset component 251 is compressed, and the first locking portion 290 is located at the locking position.
Along the axial direction, the arc-shaped groove 350 is located between the entrance 2111 of the mounting groove 211 and the arc-shaped wall 340.
The unlocking portion 281 is mounted at a bottom of the mounting groove 211. The quick connection structure 10 further includes a third reset component 252, one end of which is connected to the unlocking portion 281 and the other end is connected to the bottom of the mounting groove 211. The mounting portion 210 defines a second mounting hole 230, which extends through the annular wall 240 radially and communicates with the mounting groove 211. One end of the second locking portion 270 is connected to the unlocking portion 281, and the other end extends through the second mounting hole 230 to the outside. An end of the locking component 300 away from the entrance 2111 of the mounting groove 211 defines a limiting groove 380, which extends radially through the locking component 300 and communicates with the second mounting hole 230. The second locking portion 270 is connected to the unlocking portion 281, and is capable of moving axially under the driving of the unlocking portion 281. When the other end of the second locking portion 270 extending out of the annular wall 240 withdraws from the limiting groove 380, the locking component 300 is unlocked. When the other end of the second locking portion 270 extending out of the annular wall 240 moves into the limiting groove 380, the locking component 300 is locked. The third reset component 252 generates a force to push away the unlocking component 280 to make the second locking portion 270 extend into the limiting groove 380.
The second component 200 further includes an annular flange 260 for supporting the locking component 300 thereon. The annular flange 260 is located at a bottom side of the locking component 300, i.e., a side of the locking component 300 away from the entrance 2111, and extends beyond the annular wall 240 along the radial direction. The second mounting hole 230 extends into the annular flange 260. When the other end of the second locking portion 270 extending out of the annular wall 240 moves upwardly into an upper portion of the second mounting hole 230 (i.e., a portion in the annular wall 240) and withdraws from a lower portion of the second mounting hole 230 (i.e., a portion in the annular flange 260), the locking component 300 is locked. When the other end of the second locking portion 270 extending out of the annular wall 240 moves downwardly into the lower portion of the second mounting hole 230 and withdraws from the upper portion of the second mounting hole 230, the locking component 300 is unlocked.
The assembly process of the quick connection structure 10 of this embodiment is as follows:
The operator rotates the locking component 300 from the first position to the second position, the first locking portion 290 extends out of the annular wall 240 of the mounting portion 210 gradually and then returns to the unlocking position under the pushing force of the second reset component 251. During the rotation of the locking component 300 to the second position, after the limiting groove 380 is rotated to align with the second mounting hole 230, the second locking portion 270 in the second mounting hole 230 is pushed by the unlocking portion 281 to move axially towards the entrance 2111 of the fixing grove 211 to extend into the limiting groove 380, wherein the unlocking portion 281 is driven by the third reset component 252, thereby making the locking component 300 unable to rotate relative to the mounting portion 210, realizing locking of the locking component 300.
The operator can insert the first component 100 into the mounting groove 211 to push the unlocking portion 281 to move axially away from the entrance 2111, the second locking portion 270 withdraws from the limiting groove 380 gradually until the second locking portion 270 is unlocked. The unlocked locking component 300 rotates reversely towards the first position under the pushing of the first reset component 400, the arc-shaped wall 340 of the locking component 300 pushes the first locking portion 290 to move radially towards the central axis 241 to a position where the first component 100 is locked, thereby realizing the locking of the first component 100.
