Referring to
In this embodiment, the central rod 32 and the bottom cap 31 are fixedly connected.
The locking mechanism comprises a first magnetic element 321 arranged on the central rod 32 and a second magnetic element 331 arranged on the top cap 33. When the locking mechanism is in the locked state, the first magnetic element 321 and the second magnetic element 331 are magnetically connected, and when the locking mechanism is in the unlocked state, the first magnetic element 321 and the second magnetic element 331 are separated from each other.
Specifically, in the case where the canopy is unfolded and the central rod 32 extends above the top cap 33 as shown in
The above-mentioned lower rod 32a and upper rod 32b may be fixedly or slidably connected, specifically, the lower rod 32a has a cavity, and the upper rod 32b is telescopically inserted therewith. The slidable connection structure between the lower rod 32a and the upper rod 32b makes the overall length of the central rod 32 adjustable, and when the canopy is unfolded, the upper rod 32b slides to a suitable position relative to the lower rod 32a, for example, the lower portion of the upper rod 32b abuts against the lower rod 32a, so that the tarpaulin of the canopy is lifted to a suitable height, and when the canopy is folded, the top cap 33 slides to abut against the bottom surface of the top cover 34, and then pushes the upper rod 32b away from the lower rod 32a, so as to meet the requirement of the first top rod 21 and the second top rod 22 for the distance with the connection point of the central lock during the folding process. In particular, the overall length of the central rod 32 is substantially the same as the length of the shortened support legs 1, so that the folded canopy structure is more compact.
Specifically, in the case where the canopy is unfolded and the central rod 32 does not extend above the top cap 33 as shown in
In an embodiment, both the first magnetic element 321 and the second magnetic element 331 are annular, so that there is a relatively larger contact area and attractive force of magnetic connection therebetween.
In an embodiment, in the above two cases, the second magnetic element 331 is arranged on the upper portion of the top cap 33; when the first magnetic element 321 and the second magnetic element 331 attract each other, the second magnetic element 331 is above the first magnetic element 321, and the up-down structural arrangement can make the connection between the two more stable and prevent the two from being disengaged.
In the locking mechanism in this embodiment, when the canopy is unfolded, after the top cap 33 slides to the corresponding position, the first magnetic element 321 and the second magnetic element 331 can be automatically attracted and connected to each other, and when unlocking is required, it is only necessary to forcefully overcome the attractive force of the magnetic connection between the first magnetic element 321 and the second magnetic element 331 to separate the two to achieve unlocking.
Referring to
In this embodiment, the central rod 32 and the bottom cap 31 are fixedly connected.
The locking mechanism in this embodiment comprises a first clamping portion 322 arranged on the central rod 32 and a second clamping portion 332 arranged on the top cap 33, and when the locking mechanism is in the locked state, the first clamping portion 322 is clamped with the second clamping portion 332, and when the locking mechanism is in the unlocked state, the first clamping portion 322 and the second clamping portion 332 are separated.
Specifically, in the above two cases (the canopy is unfolded with the case of the central rod 32 extending above the top cap 33 and the case of the central rod 32 not extending above the top cap 33), the central rod 32 is provided with a protrusion 324, the protrusion 324 is annular, and the protrusion 324 is provided with a plug-in portion 325 protruding upward; the first clamping portion 322 protrudes outward from the outer wall of the plug-in portion 325, and the top cap 33 has an extension portion 337 protruding downward, there is a gap between the extension portion 337 and the central rod 32, the gap forms an insert slot 336, and the second clamping portion 332 is a slot disposed on the inner wall of the insert slot 336; when the canopy is unfolded, as the top cap 33 and the central rod 32 slide with respect to each other, the plug-in portion 325 is inserted into the insert slot 336 of the top cap 33, the first clamping portion 322 and the second clamping portion 332 are clamped and connected to each other through the elasticity of the material itself, and at the same time, the protrusion 324 supports the top cap 33.
In the locking mechanism in this embodiment, when the canopy is unfolded, after the top cap 33 slides to the corresponding position, the first clamping portion 322 and the second clamping portion 332 can be clamped tightly through the elasticity of the material itself, and when unlocking is required, the unlocking can be achieved by forcefully separating the first clamping portion 322 from the second clamping portion 332.
Referring to
In this embodiment, the central rod 32 and the bottom cap 31 are rotatably (such as pivotally) connected. Besides sliding relative to each other, the central rod 32 and the top cap 33 can also rotate (such as pivot) relative to each other.
The locking mechanism comprises a protruding portion 323 arranged on the central rod 32 and a helical groove 333 arranged on the top cap 33. In an embodiment, there are two protruding portions 323 symmetrically arranged on both sides of the central rod 32, and correspondingly, there are also two symmetrically arranged helical grooves 333. Specifically, the protruding portions 323 may be a pin connected to the central rod 32, more specifically, the pin is fixedly inserted on the central rod 32 and two ends of the pin protrude from the central rod 32 to form two symmetrical protruding portions 323. Each helical groove 333 has an initiating end and a terminal end, and a limiting groove matched with a protruding portion 323 is provided at the terminal end. The locking mechanism further comprises an elastic element 35 arranged between the bottom cap 31 and the central rod 32, and the elastic element 35 is a torsion spring, and in the above two cases (the canopy is unfolded with the case of the central rod 32 extending above the top cap 33 and the case of the central rod 32 not extending above the top cap 33), the central rod 32 is manually rotated to switch the locking mechanism to the locked state, and during the process of switching to the locked state, the protruding portions 323 are rotated from the initiating ends of the helical grooves 333 to the terminal ends of the helical grooves 333, and at this time, the torsion spring is in a deformed state, so after the external force is removed, the protruding portions 323 rotate back into the limiting grooves and abut against the groove walls of the limiting grooves, and when the protruding portions 323 are clamped in the limiting grooves, the torsion spring is restored to the natural state (the second choice is to restore to a near-natural state); when it needs to convert the locking mechanism from the locked state to the unlocked state, the rotatable operation part on the bottom cap 31 is manually operated, and the rotatable operation part can drive the torsion spring to rotate, and then the torsion spring exerts a force on the central rod 32 to make the protruding portions 323 disengage from the limiting grooves and move from the terminal ends of the helical grooves 333 to the initiating ends, and finally exit the helical grooves 333.
Inan embodiment, the central rod 32 is further provided with a stopper block 326, the stopper block 326 is annular, and the stopper block 326 is located below the protruding portions 323, and when the locking mechanism is locked, the stopper block 326 support the top cap 33 to relieve the force of the protruding portions 323.
Further referring to
In the locking mechanism in this embodiment, when the canopy is unfolded, after the top cap 33 slides to the corresponding position, the protruding portions 323 on the central rod 32 correspond to the positions of the corresponding helical grooves 333 and enter from the shallow ends of the helical grooves 333. When the protruding portions 323 slide in depth along the helical grooves 333, under the interaction between the helical grooves 333 and the protruding portions 323, the central rod 32 is rotated relative to the top cap 33 and the bottom cap 31, and under the action of the elastic element 35, the protruding portions 323 will press against the limiting grooves at the terminal ends in the helical grooves 333 and will not come out. When unlocking is required, the rotatable operation part on the bottom cap 31 is rotated to rotate the elastic element 35 to drive the central rod 32 to rotate, the rotation direction of the central rod 32 during the unlocking operation is opposite to the rotation direction during the locking operation, so that the protruding portions 323 exit the helical grooves 333, that is, the unlocking is realized.
Referring to
This embodiment mainly defines that the locking position locates at the lower portion of the central rod 32, and the top of the central rod 32 is not configured with the top cover 34 as described in the some previous embodiments, and then when the canopy is in the folded state, the top cap 33 moves upward and finally disengages from the central rod 32. Therefore, it can optionally be combined with the specific implementations of the locking mechanisms in the above-mentioned Embodiments 1 to 8, for example, the locking mechanism comprising the first magnetic element 321 and the second magnetic element 331 in Embodiment 6, for another example, the locking mechanism comprising the first clamping portion 322 and the second clamping portion 332 in Embodiment 7, for yet another example, the locking mechanism comprising the protruding portion 323 and the helical groove 333 in Embodiment 8.
It should be noted that the protruding portion 323 and the stopper block 326 on the central rod 32 shown in
In the collapsible canopies in the above mentioned embodiments, by arranging the locking mechanism between the top cap and the central rod, it can simplify the structure of the locking mechanism and save costs; in addition, the central rod has a length that is not limited by a canopy folding structure any more, and can be extended upwardly to raise the tarpaulin. At the same time, when performing the unlocking operation, the operation part is at the bottom of the entire central lock, and the operator does not need to pass his/her hand through the inner retractable units to operate, which is more convenient and labor-saving.
