Description
Technical Field
[0001] This utility model relates to the field of coupler installation technology, specifically a coupler with a snap-fit guiding structure. Background Technology
[0002] A coupler is a connector widely used in many fields such as electronics, communications, and mechanics. Its main function is to enable a detachable connection between two components to facilitate the installation, disassembly, maintenance, or replacement of the components. However, existing couplers still have some problems when used: Traditional couplers typically require aligning the two coupling components before locking them together during connection. However, due to the lack of an effective guiding structure, misalignment of the two coupling components is common in actual operation, leading to difficulty in locking, affecting connection efficiency, and potentially damaging the coupler due to forced locking.
[0003] In view of this, in-depth research was conducted on the above issues, which led to the creation of this case.
[0004] To address the aforementioned issues, an innovative design was developed based on the existing coupler. Utility Model Content
[0005] The purpose of this invention is to provide a coupler with a locking guide structure to solve the problem mentioned in the background art that when connecting couplers, it is usually necessary to align the two coupling components before locking and fixing them. However, due to the lack of an effective guide structure, in actual operation, the two coupling components are easily misaligned, resulting in difficulty in locking, affecting connection efficiency, and even potentially damaging the coupler due to forced locking.
[0006] To achieve the above objectives, this utility model provides the following technical solution: A coupler with a snap-fit guiding structure includes a first coupler assembly and a second coupler assembly. The second coupler assembly is disposed above the first coupler assembly. A groove is formed in the middle of the first coupler assembly. A boss that matches the groove is fixed to the bottom of the second coupler assembly. A positioning block is fixed to the upper end face of the first coupler assembly. A positioning groove that matches the positioning block is formed to the bottom of the second coupler assembly. Protrusions are fixed to both sides of the first coupler assembly. A snap-fit groove is formed in the middle of the protrusion. Snap-fit blocks that match the snap-fit grooves are fixed to both sides of the second coupler assembly. A limiting groove is formed in the middle of the snap-fit block. Sliding grooves are formed on both sides of the first coupler assembly. A spring is fixed to the inner wall of the sliding groove. A limiting block that matches the limiting groove is fixed to the end of the spring.
[0007] By adopting the above technical solution, the first coupler assembly is initially positioned by the groove of the first coupler assembly and the boss, positioning block and positioning groove of the second coupler assembly. Then, the snap-fit block is snapped into the snap-fit groove, and the limiting block is snapped into the limiting groove under the action of the spring to achieve a stable engagement. This enables the first coupler assembly and the second coupler assembly to be accurately docked and firmly connected, ensuring stable operation of the coupler and preventing loosening and disconnection.
[0008] Preferably, a first through hole is provided at the center of the first coupler assembly and in the middle of the groove, and a second through hole is provided at the center of the second coupler assembly and in the middle of the boss.
[0009] Using the above technical solution, a first through hole and a second through hole are respectively provided at the center of the first coupler assembly and the center of the second coupler assembly, located in the middle of the groove and the boss, so that the two through holes can be naturally aligned when the components are connected. These two through holes can be used to pass through components such as cables and pipes to realize the connection between the coupler and other devices, and meet the functional requirements of signal and material transmission.
[0010] Preferably, the positioning block is a rectangular block, and two sets of positioning blocks are symmetrically arranged along the upper end face of the first coupler assembly.
[0011] Using the above technical solution, the rectangular positioning block has a regular shape and clear edges and corners. Two sets of symmetrically arranged positioning reference systems can form a stable and balanced positioning system. By matching it with the positioning slot, precise positioning can be achieved, which can ensure that the first coupler assembly and the second coupler assembly are in the correct direction and fixed position when docking, avoiding offset or misalignment, and ensuring the reliability and stability of the coupler connection.
[0012] Preferably, the snap-fit block has an inverted L-shaped structure, and one side of the snap-fit block is engaged with the snap-fit groove.
[0013] Using the above technical solution, the inverted L-shaped snap-fit block has a unique shape, with one side matching the shape and size of the snap-fit groove. The right-angled side and horizontal side of the inverted L shape respectively engage with different parts of the snap-fit groove to achieve a stable connection. This can enhance the connection strength between the first coupler assembly and the second coupler assembly, prevent relative displacement between the two in the horizontal or vertical direction, and improve the stability and reliability of the overall coupler connection.
[0014] Preferably, the limiting block has an inverted L-shaped structure, and two sets of limiting blocks are symmetrically arranged along the first coupler assembly, and the limiting block and the limiting groove are correspondingly engaged.
[0015] Using the above technical solution, the inverted L-shaped limiting block utilizes its unique right-angle shape. When the locking block is inserted into the locking groove, the two sets of symmetrically arranged limiting blocks are subjected to the action of springs, and their right-angled sides can be accurately embedded into the corresponding limiting grooves, forming multi-directional constraints. This effectively prevents the first coupler assembly and the second coupler assembly from becoming loose, shaking, or accidentally disengaging after connection, greatly enhancing the stability and reliability of the connection and ensuring stable operation of the coupler.
[0016] Preferably, the first coupler assembly has six sets of first screw holes in a ring shape above it, and the second coupler assembly has six sets of second screw holes in a ring shape above it, corresponding to the first screw holes. A screw rod is threaded through the middle of the first screw hole and the second screw hole, and a nut is sleeved on the top of the screw rod.
[0017] Using the above technical solution, six sets of screw holes are opened in a ring on the first coupler assembly and the second coupler assembly respectively. When the two assemblies are connected, the screw holes are aligned, the screw rod passes through the first screw hole and the second screw hole, and then the nut is tightened by the threaded engagement of the screw rod. The threaded connection of the screw rod and the nut provides a strong and stable fastening force, which further enhances the firmness of the connection between the first coupler assembly and the second coupler assembly, prevents the components from separating, and ensures safe and reliable use.
[0018] Compared with the prior art, the beneficial effects of this utility model are: the coupler with a locking and guiding structure, 1. The boss of the second coupler assembly and the groove of the first coupler assembly are mutually adapted to each other, which can quickly achieve initial positioning; at the same time, the cooperation of the two sets of rectangular positioning blocks and positioning grooves further ensures the accuracy of the installation direction and prevents the components from being misaligned; moreover, the engagement of the inverted L-shaped snap-fit block and the snap-fit groove, as well as the precise docking of the inverted L-shaped limiting block with the limiting groove under the action of the spring, enable the two components to be quickly and firmly connected together, which greatly shortens the installation time, reduces the installation difficulty, and improves work efficiency. 2. On the one hand, the engagement of the snap-fit block and the snap-fit groove, and the engagement of the limiting block and the limiting groove, constrains the two coupler components from multiple directions, effectively preventing relative movement of the components in the horizontal or vertical direction and enhancing the stability of the connection; on the other hand, the six sets of first and second screw holes that are annularly opened above the first and second coupler components, connected by the threads of the screw and nut, provide a strong fastening force for the entire connection structure, further ensuring that the two components will not loosen or separate.
