The present disclosure relates to the field of car accessories technologies, and in particular, to a roof box fast clip.
Nowadays, most vehicles use luggage compartments with horizontal bar brackets connecting the luggage bars. There are many ways to connect the luggage compartment to the horizontal bar brackets, such as clip mechanisms, bolt connections, etc. However, these structures are very inconvenient to install and have complex structures;
The existing clamp mechanism includes a pair of claws and a transmission mechanism that links the two together. The transmission mechanism is controlled by a knob, and the relative motion between the claws is manually rotated to control the clamping and releasing of the crossbar bracket by the claws. In addition, the clamp mechanism also includes a locking component. After the claws clamp the crossbar bracket, the locking component is moved to lock the position of the claws. This structure has the problems of complex structure and long operation time;
Also, the clamp mechanism is used to clamp the crossbar bracket through the shell of the luggage compartment. The existing clamp mechanism has a complex structure, large thickness, and is prone to occupying space in the luggage compartment.
In order to overcome the shortcomings of the background technology, the present utility model provides a fast clip of roof box compartment with a simple structure and easy operation.
The technical solution adopted by the present utility model is a fast clip for a roof box compartment, which comprises a cover plate, a base, a locking mechanism, and a first clamping piece and a second clamping piece that are slidably installed inside the base and are relatively arranged. The locking mechanism is flexibly installed on the base and is elastically connected to the first clamping piece. The cover plate is hinged and installed on the base and is linked to the second clamping piece. The first clamping piece has a first state of sliding and cooperating with the base after the locking mechanism is unlocked, and a second state of being fixed on the base after the locking mechanism is locked. The second clamping piece has a first state of sliding backward when the cover plate is opened and a first state of clamping towards the first clamping piece when the cover plate is closed. The second state of sliding in the direction of the component.
The first clamping component comprises a first sliding block portion installed in the base and a first hook portion extending downward and passing through the base. The bottom surface of the base is provided with a first passage groove for the first hook portion to pass through.
The second clamping component comprises a second sliding block portion installed in the base by sliding, and a second hook portion extending downward and passing through the base. The bottom surface of the base is provided with a second passage groove for the second hook portion to pass through.
In an embodiment of the present disclosure, the locking mechanism is provided with a first ratchet portion, and the inner bottom surface of the base is provided with a second ratchet portion that meshes with the first ratchet portion. The locking mechanism has a first state in which the first ratchet portion and the second ratchet portion mesh when not under force, and a second state in which the first ratchet portion and the second ratchet portion separate after being under force.
The locking mechanism comprises:
The upper surface of the locking block is provided with a pressing plate, and the connection point between the connecting bolt and the locking block is located between the pressing plate and the first ratchet portion. The pressing plate is located behind the connection point and the first ratchet portion is located in front of the connection point. There is a height difference between the pressing plate and the first slider portion.
The locking block is equipped with a hook plate at a position in front of the pressing plate, and there is a distance for fingers to insert between the hook plate and the first ratchet portion.
The locking block is equipped with a first mounting hole for connecting bolts to pass through, and the first clamping component is equipped with a second mounting hole for connecting bolts to pass through. Both the first and second mounting holes are strip-shaped holes.
The cover plate is hinged and installed at the end position of the base. The lower surface of the cover plate is provided with an installation seat, and a linkage rod is provided between the installation seat and the second clamping member for hinged connection. The inner walls on both sides of the base are provided with sliding grooves for embedded sliding installation of the second sliding block.
The base is composed of a left support and a right support arranged opposite to each other, and the left support and the right support are fixedly connected by bolts; There are through holes on both sides of the base for straps to pass through.
The beneficial effect of this utility model is that the first clamping component of the technical solution can slide on the base after the locking mechanism is unlocked. When the first clamping component and the second clamping component clamp an object and the locking mechanism is locked, the first clamping component is fixed and cannot move. During the process of turning the cover plate from open to closed, the cover plate can drive the second clamping component to slide in the direction of the first clamping component on the base, improving the clamping force on the object. It has the advantages of simple structure and convenient operation.
The following is a further explanation of the embodiments of the present disclosure in combination with the drawings.
As shown in the drawings, the fast clip of the roof box compartment includes a cover plate 1, a base 2, a locking mechanism 5, and a first clamping piece 3 and a second clamping piece 4 that are slidably installed inside the base 2 and are relatively arranged. The locking mechanism 5 is flexibly installed on the base and is elastically connected to the first clamping piece 3. The cover plate 1 is hinged and installed on the base 2 and is linked to the second clamping piece 4. The first clamping piece 3 has a first state of sliding and cooperating with the base 2 after the locking mechanism 5 is unlocked, and a second state of being fixed on the base 2 after the locking mechanism 5 is locked. The second clamping piece 4 has a backward position when the cover plate 1 is opened. The first state of sliding and the second state of sliding towards the first clamping component 3 when the cover plate 1 is closed; The first clamping component of this technical solution can slide on the base after the locking mechanism is unlocked. When the first clamping component and the second clamping component clamp an object and the locking mechanism is locked, the first clamping component is fixed. During the process of turning the cover plate from open to closed, the cover plate can drive the second clamping component to slide in the direction of the first clamping component on the base, improving the clamping force on the object. It has the advantages of simple structure and convenient operation.
In addition, the fast clip structure in this embodiment is simple and has a flattened structure. The thickness of the cover plate can be made thin, and the installation positions of the first clip, the second clip, and the locking mechanism are all on the same horizontal plane, greatly reducing the occupied space and allowing the luggage compartment on the roof to have more space to accommodate luggage.
The installation process of this technical solution is as follows:
In step 3, the object is fixed and immovable. Specifically, it is a horizontal bar bracket on the roof for installing the luggage compartment. The distance between the first clamping piece and the locking mechanism can compensate for the margin, and the elastic piece provides a pre tension force for the first clamping piece to always resist the object. When the first clamping piece moves towards the locking block direction and reaches the limit position, it is just below the pressing plate. At this time, the pressing plate cannot be pressed down, and there will be no accidental unlocking situation.
The left and right sides in step 1 can be determined according to
The locking mechanism in this embodiment adopts elastic fit with the first clamping member, and there is a distance between them. Therefore, when clamping an object and the second clamping member is driven by the cover plate to move in the direction of the first clamping member, the first clamping member will be pushed by the force transmitted by the second clamping member to slide in the direction of the locking mechanism for a certain distance. Under the action of elastic force, the first clamping member and the second clamping member always firmly clamp the object.
The first clamping component 3 comprises a first sliding block portion 31 installed in the base 2 and a first hook portion 32 extending downward and passing through the base 2. The bottom surface of the base 2 is provided with a first passage groove 21 for the first hook portion 32 to pass through, and the first sliding block portion drives the first hook portion to pass through the first passage groove during sliding.
The second clamping component 4 includes a second sliding block portion 41 that is slidably installed inside the base 2, and a second hook portion 42 that extends downward and passes through the base 2. The bottom surface of the base 2 is provided with a second passage groove 22 for the second hook portion to pass through, and the second clamping component has the same motion principle as the first clamping component.
The locking mechanism is provided with a first ratchet portion 55, and the inner bottom surface of the base is provided with a second ratchet portion that meshes with the first ratchet portion. The locking mechanism has a first state in which the first ratchet portion 55 and the second ratchet portion 23 mesh when not under force, and a second state in which the first ratchet portion 55 and the second ratchet portion 23 separate after being under force.
The locking mechanism 5 comprises:
The upper surface of the locking block 51 is provided with a pressing plate 56, and the connection point between the connecting bolt 52 and the locking block 51 is located between the pressing plate 56 and the first ratchet portion 55. The pressing plate 56 is located behind the connection point and the first ratchet portion 55 is located in front of the connection point. The elastic member is in contact with the locking block 51 and the first clamping member, and the distance between the first clamping member and the locking block provides a margin for the movement of the first clamping member; Because in step 1, after the first clamping piece and the second clamping piece clamp the object, under the action of the cover plate, the second clamping piece will be driven to move in the direction of the first clamping piece. On the premise that the distance between the first clamping piece and the second clamping piece remains unchanged, the first clamping piece will inevitably move in the direction of the locking block. After the cover plate is closed, the side wall of the first clamping piece will contact and cooperate with the side wall of the locking block, and the first teeth of the locking block will cooperate with the second teeth of the base to provide support for the first clamping piece.
Among them, in the unlocked state, the elastic member can maintain an appropriate distance between the locking block and the first clamping member, and the connecting bolt and nut can adjust the size of the distance. In the locked state, the first clamping member moves in the direction of the locking block after receiving the force transmitted by the second clamping member, overcoming the pre tightening force of the elastic member and eliminating the distance.
In addition, the first and second ratchet teeth in this embodiment are engaged, which can achieve the locking of the locking block and the base. As shown in
The upper surface of the locking block 51 is provided with a pressing plate 56, and the connection point between the connecting bolt 52 and the locking block 51 is located between the pressing plate 56 and the first ratchet portion 55. The pressing plate 56 is located behind the connection point and the first ratchet portion 55 is located in front of the connection point. When the pressing plate is under force, due to the lever principle, the first ratchet portion will lift upward, allowing the locking block to separate from the base and achieve unlocking. After unlocking, the locking mechanism can slide freely on the base with the first clamping member, and the elastic member can provide pre tension for the reset of the locking block.
There is a height difference between the pressing plate 56 and the first slider portion 31. In step 3, when the first clamping member overcomes the pre tension force of the elastic member and moves towards the locking mechanism, the first clamping member is located below the pressing plate. This way, the pressing plate will be blocked by the first clamping member, preventing the locking block from being subjected to force and causing it to lift and unlock.
The locking block 51 is provided with a first mounting hole 57 for the connecting bolt 52 to pass through, and the first clamping member 3 is provided with a second mounting hole 58 for the connecting bolt 52 to pass through. Both the first and second mounting holes use strip-shaped holes, and when the locking block is lifted, the connecting bolt will have a restriction on both. Therefore, in order to lift this restriction, strip-shaped holes are provided on the locking block and the first clamping member, so that when the locking block is lifted under pressure, the connecting bolt also swings upward at an appropriate angle. The elastic member provides pre tension for the reset of the locking block.
The locking block 51 is provided with a hook plate 59 at a position in front of the pressing plate 56, and there is a distance for fingers to insert between the hook plate 59 and the first ratchet portion 55. In this embodiment, there is another unlocking method, which can also lift the first ratchet portion upward by hooking the hook plate with fingers.
The cover plate 1 is hinged and installed at the end position of the base 2. The lower surface of the cover plate 1 is provided with an installation seat 11, and a linkage rod 6 is provided between the installation seat and the second clamping member 4 for hinged connection. The inner walls on both sides of the base 2 are provided with sliding grooves 26 for the embedded sliding installation of the second sliding block part 41. During the opening and closing process, the cover plate drives the second clamping member to slide in the sliding groove through the linkage rod.
The base 2 consists of a left support 24 and a right support 25 arranged opposite each other on the left and right sides. The left support 24 and the right support 25 are fixedly connected by bolts, and the installation of each component is more convenient by setting up the left and right supports.
The two sides of the base 2 are provided with through holes 7 for straps to pass through, and the straps can fix the luggage inside the luggage compartment.
