Abstract
Description
Technical Field
[0001] This utility model relates to the field of quick-release connector technology, and in particular to a quick-release structure. Background Technology
[0002] In the field of modern mechanical connection and assembly, quick-release connectors, as a key structure for enabling rapid assembly and disassembly of components, have been widely used in various scenarios, particularly in the installation and fixing of motorcycle lights and the component connection of cycling photography brackets. These connection structures, through flexible docking and locking mechanisms, can significantly improve the operational efficiency of equipment during maintenance, replacement, or adjustment, meeting users' core needs for convenience and practicality.
[0003] Existing quick-release connectors typically consist of two core mating components: a first connector and a second connector. These two components achieve initial positioning and mating through a pre-designed mating structure. To ensure stability and security after connection and prevent accidental separation due to vibration, collisions, or other external forces during use, the quick-release connector also needs to be equipped with a corresponding locking device. This locking device is generally integrated with or linked to the first or second connector, and after mating, it securely locks the two connectors, thus preventing disassembly and detachment, and ensuring reliable operation of the equipment under complex working conditions.
[0004] However, as the market demands increasingly higher product cost-effectiveness and production efficiency, the existing quick-release connector structure design has gradually revealed significant limitations. Specifically, current mainstream quick-release structures generally suffer from complex designs: some structures even require additional linkage mechanisms to coordinate the lock's movement. This complex design directly results in a large number of parts, which not only increases the difficulty of mold development and manufacturing costs but also makes material management and assembly processes more cumbersome. Too many parts require higher assembly precision to ensure reliable fit, making it highly susceptible to errors in a single component that could lead to a decrease in overall assembly efficiency and even affect product consistency and stability.
[0005] Furthermore, the increased number of components also increases the risk of product failure during long-term use. For example, wear, loss, or jamming of small parts can reduce the lifespan of the quick-release connector and the user experience. Therefore, simplifying the structure of the quick-release connector, reducing the number of components, and lowering production costs and improving assembly efficiency while ensuring connection strength and locking reliability have become urgent technical problems to be solved in this field. Utility Model Content
[0006] The present invention aims to solve at least one of the technical problems existing in the prior art. To this end, the present invention proposes a quick-release structure with a simple structure and a small number of parts.
[0007] A quick-release structure designed for this purpose includes a first connecting seat, a second connecting seat, a movable locking pin, a resilient element, and a lock.
[0008] The first connector is provided with an installation cavity and a connecting cavity that are in communication with each other, and the connecting cavity has an opening on its upper side;
[0009] The second connector is provided with a connecting part that can be inserted into the connecting cavity from top to bottom, and the connecting part is provided with a mating part that extends toward the mounting cavity.
[0010] The movable locking pin is disposed within the mounting cavity and is movable relative to the mounting cavity between a locked position and an unlocked position; the movable locking pin is provided with a locking portion extending into the connecting cavity;
[0011] When the movable locking pin is in the locked position, the locking part is located above the mating part, which can constrain the mating part to move upward;
[0012] When the movable locking pin is in the unlocked position, the locking part and the mating part are misaligned, and the second connecting seat together with the mating part can move upward relative to the first connecting seat;
[0013] The elastic element is used to apply force to the movable locking pin, thereby driving the movable locking pin to move toward the locking position;
[0014] The lock is used to constrain the position of the movable locking pin. When the lock is locked, the movable locking pin cannot move toward the unlocked position.
[0015] Preferably, the mounting cavity extends at least partially through the first connecting seat, thereby communicating with the outside of the first connecting seat.
[0016] Preferably, an unlocking button is provided on the outer side of the first connecting seat, and the unlocking button is fixedly connected to the movable locking pin.
[0017] The elastic element is used to push the movable locking pin toward the unlock button.
[0018] Preferably, the rotating lock cylinder of the lock is connected to a locking plate, which abuts against the unlock button or the movable lock pin, thereby constraining the movable lock pin to move from the locked position to the unlocked position.
[0019] Preferably, the unlock button and the movable lock pin are connected by an anti-theft bolt.
[0020] Preferably, the upper surface of the first connector is provided with a plurality of positioning holes, and the second connector is provided with a positioning post that is inserted into the positioning holes.
[0021] Preferably, the first connecting seat is provided with a limiting element, the movable locking pin is provided with a limiting engagement part, and the limiting element and the limiting engagement part are inserted into each other.
[0022] This quick-release structure, through its scientifically and rationally configured and designed components, can bring about many beneficial effects:
[0023] First, the overall structure is significantly simplified. The solution achieves quick-release functionality through the cooperation of core components such as the first connecting seat, the second connecting seat, the movable locking pin, the elastic element, and the lock, eliminating the need for complex linkage mechanisms. This effectively reduces the number of parts, lowers mold development difficulty and manufacturing costs, improves assembly efficiency, and facilitates mass production.
[0024] Secondly, it achieves efficient locking and unlocking operations. The connecting part of the second connecting seat can be directly inserted into the connecting cavity of the first connecting seat from top to bottom. The mating part and the locking part of the movable locking pin form a constraint through positional cooperation. Under the force of the elastic element, the movable locking pin can automatically tend to the locking position, ensuring the stability after connection. When unlocking, it is only necessary to release the constraint of the lock on the movable locking pin, so that the movable locking pin can switch to the unlock position to achieve separation. The whole process is convenient and greatly improves the efficiency of disassembly and assembly.
[0025] Furthermore, it ensures the reliability and security of the connection. Under the action of the elastic element, the movable locking pin always tends to move towards the locked position. Combined with the position constraint of the movable locking pin when the lock is locked, it can effectively prevent accidental unlocking caused by external forces such as vibration and collision, ensuring that the second connecting seat and the first connecting seat are firmly connected, avoiding separation caused by the upward movement of the mating parts, and significantly improving the stability and security of the structure during use.
[0026] Furthermore, it extends service life and enhances user experience. The reduced number of parts lowers the risk of wear, loss, or jamming of small components, and the stabilizing force of elastic elements ensures the long-term reliability of the structure. At the same time, the simple operation and stable connection performance greatly improve the user experience during installation and maintenance. Attached Figure Description

[0041] See Figures 1-6 A quick-release structure includes a first connecting seat 10, a second connecting seat 20, a movable locking pin 30, an elastic element 300, and a lock 40.
[0042] The first connecting seat 10 is provided with an installation cavity 100 and a connecting cavity 110 that are in communication with each other, and the connecting cavity 110 has an opening on its upper side;
[0043] The second connecting seat 20 is provided with a connecting part 210 that can be inserted into the connecting cavity 110 from top to bottom, and the connecting part 210 is provided with a mating part 211 extending toward the mounting cavity 100.
[0044] The movable locking pin 30 is disposed within the mounting cavity 100 and is movable relative to the mounting cavity 100 between a locked position and an unlocked position; the movable locking pin 30 is provided with a locking portion 310 extending into the connecting cavity 110;
[0045] When the movable locking pin 30 is in the locked position, the locking part 310 is located above the mating part 211, which can constrain the mating part 211 to move upward.
[0046] When the movable locking pin 30 is in the unlocked position, the locking part 310 and the mating part 211 are misaligned with each other, and the second connecting seat 20 together with the mating part 211 can move upward relative to the first connecting seat 10.
[0047] The elastic element 300 is used to apply force to the movable locking pin 30, thereby driving the movable locking pin 30 to move toward the locking position.
[0048] The lock 40 is used to constrain the position of the movable locking pin 30. When the lock 40 is locked, the movable locking pin 30 cannot move toward the unlocked position.
[0049] The working principle of this quick-release structure revolves around switching between two states: locked and unlocked, as detailed below:
[0050] During connection locking, the connecting portion 210 of the second connecting seat 20 is aligned from top to bottom with the connecting cavity 110 of the first connecting seat 10 and inserted. At this time, the movable locking pin 30 is in the locked position under the force of the elastic element 300, and its locking portion 310 extends into the connecting cavity 110 and is located above the mating portion 211. When the connecting portion 210 is fully inserted into the connecting cavity 110, the mating portion 211 is directly below the locking portion 310, and the locking portion 310 constrains the mating portion 211 to move upward. Then, the lock 40 is locked, fixing the position of the movable locking pin 30 so that it cannot move towards the unlocked position, thereby achieving a stable lock between the first connecting seat 10 and the second connecting seat 20.
[0051] When unlocking and separation are required, first operate the lock 40 to switch it to the unlocked state, releasing the positional constraint on the movable locking pin 30. At this time, apply external force to make the movable locking pin 30 overcome the force of the elastic element 300 and move from the locked position to the unlocked position. The locking part 310 then misaligns with the mating part 211, no longer constraining the mating part 211. Subsequently, the second connecting seat 20, together with the mating part 211, can be moved upward relative to the first connecting seat 10, causing the connecting part 210 to disengage from the connecting cavity 110, completing the unlocking and separation. When the external force is removed, the movable locking pin 30 will automatically return from the unlocked position to the locked position under the action of the elastic element 300, for the next connection and use.
[0052] In this invention, the locking part 310 has a sloped surface at one end facing the connecting cavity 110, which slopes downwards towards the mounting cavity 100. The mating part 211 has a reverse sloped surface (sloping downwards away from the mounting cavity 100) on the side facing the mounting cavity 100, which matches the angle of the sloped surface of the locking part 310. When the connecting part 210 is inserted, the two sloped surfaces contact and engage, and the mating part 211 can naturally push the locking part 310 towards the mounting cavity 100, achieving automatic avoidance.
[0053] In this invention, the mounting cavity 100 at least partially penetrates the first connecting seat 10 and communicates with the outside, which facilitates the application of force to the movable locking pin 30 inside the mounting cavity 100 from the outside to switch its position, and also provides operating space for the assembly, maintenance and installation of the elastic element 300.
[0054] See Figures 1 to 5 An unlock button 50 is provided on the outer side of the first connecting base 10, and the unlock button 50 is fixedly connected to the movable locking pin 30. The elastic element 300 is used to push the movable locking pin 30 to move in the direction of the unlock button 50. When pressed, it can directly drive the movable locking pin 30 to move to switch to the unlock position; the elastic element 300 pushes the movable locking pin 30 to move in the direction of the unlock button 50, which can realize the automatic reset of the button and the locking pin.
[0055] Specifically, the unlock button 50 and the movable lock pin 30 are connected by anti-theft bolts, which not only ensures that the two move synchronously to achieve the unlocking function, but also prevents others from disassembling them at will, thus improving the anti-theft performance of the structure.
[0056] See Figure 4 The rotating lock cylinder of the lock 40 is connected to a locking plate 60. The locking plate 60 abuts against the unlock button 50 or the movable locking pin 30, thereby restricting the movable locking pin 30 from moving from the locked position to the unlocked position. Based on the principle of the mechanical lock 40, when the key is inserted and the lock cylinder is turned, the lock cylinder drives the locking plate 60 to rotate synchronously: a 90-degree clockwise rotation causes the locking plate 60 to abut against the unlock button 50 or the movable locking pin 30, completing the locking; a 90-degree counterclockwise rotation causes the locking plate 60 to separate from the unlock button 50 or the movable locking pin 30, allowing the movable locking pin 30 to move.
[0057] See Figure 4 The locking plate 60 abuts against the unlock button 50 to achieve locking.
[0058] In this utility model, when a locking scheme is required to achieve locking by abutting the locking plate 60 and the movable locking pin 30, a protrusion needs to be provided on the movable locking pin 30, and the protrusion is used to abut against the locking plate 60.
[0059] In this invention, the upper surface of the first connecting seat 10 is provided with a plurality of positioning holes 120, and the second connecting seat 20 is provided with positioning pins 220 that are inserted into the positioning holes 120. The positioning holes 120 of the first connecting seat 10 and the positioning pins 220 of the second connecting seat 20 are mutually inserted and engaged, which can quickly and accurately position the two, ensuring that key structures such as the connecting part 210 and the connecting cavity 110, and the mating part 211 and the locking part 310 are accurately aligned, thereby improving assembly efficiency and connection stability.
[0060] See Figure 5 and Figure 6The first connecting seat 10 is provided with a limiting element 70, and the movable locking pin 30 is provided with a limiting mating part 320. The limiting element 70 and the limiting mating part 320 are inserted into each other. The insertion and mating of the limiting element 70 of the first connecting seat 10 and the limiting mating part 320 of the movable locking pin 30 can limit the movement range of the movable locking pin 30, preventing it from shifting or falling off during locking or unlocking, and ensuring the accuracy and stability of the movement of the movable locking pin 30. In addition, existing limiting structures can also be used to constrain the movement range of the movable locking pin 30.
[0061] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection of this utility model is defined by the appended claims and their equivalents.
