Description

Technical Field

[0001] The utility model relates to the technical field of one-piece connectors, and specifically relates to a one-piece connector with secondary locking. Background Art

[0002] A connector locking structure with a secondary lock and a connector disclosed in the publication number CN221057752U includes a plug body, on which a receiving cavity is provided. A primary lock is arranged in the receiving cavity. The primary lock is fixedly connected in the receiving cavity through a connecting column, so that the primary lock forms a "see-saw" structure. A strip-shaped groove is arranged in the middle of the primary lock. Secondary lock stopping hanging platforms are arranged on both sides of the receiving cavity. The secondary lock has a cantilever hanging nose in the middle and cantilever spring tongues on both sides. The secondary lock is horizontally inserted into the receiving cavity. When the front end face of the cantilever hanging nose abuts against the front end of the strip-shaped groove, the cantilever spring tongues are engaged with the secondary lock stopping hanging platforms to achieve primary locking.

[0003] Its socket body is provided with a convex platform. When the plug body is inserted into the socket body, the convex platform pushes up the front end of the cantilever hanging nose. At this time, the secondary lock is pushed to make the front end of the cantilever hanging nose buckle on the front end face of the primary lock to achieve secondary locking. This locking structure has high reliability, simple and convenient operation, and low cost.

[0004] The technical solution in this comparative document has the effects of low cost and simple operation, but the defects brought are more obvious. For example, using materials with self-elasticity to achieve the locking and unlocking of the secondary lock will cause the self-locking structure to fail due to the loss of material elasticity after long-term use. The service life of this self-locking structure is limited in this solution. Content of the Utility Model

[0005] In view of the deficiencies of the prior art, the utility model provides a one-piece connector with secondary locking, which solves the problem that using materials with self-elasticity to achieve the locking and unlocking of the secondary lock will cause the self-locking structure to fail due to the loss of material elasticity after long-term use, and the service life of this self-locking structure is limited in this solution.

[0006] To achieve the above object, the utility model provides the following technical solution: A one-piece connector with secondary locking includes a connector head. One end of the connector head is inserted with a connector seat. The top surface of the connector head is symmetrically provided with clamping blocks, and a connecting component is clamped on the surface of the clamping blocks. Clamping components are symmetrically arranged on both sides of the connector seat, and a clamping column is clamped inside the clamping components. The clamping column is installed on the side surface of the connector head through a side plate sleeved at one end.

[0007] The connecting component includes a bottom plate fixedly connected to the top surface of the connecting seat, and vertical plates are symmetrically arranged on the top surface of the bottom plate. A rotating rod is arranged inside the vertical plate, and a rotatable clamping plate is arranged on the surface of the rotating rod. A sleeve hole is formed on the surface of the clamping plate, and a limiting structure is arranged inside the sleeve hole.

[0008] In a specific embodiment, the limiting structure includes a limiting rod sleeved inside the hollow part and rotatable, and a bearing is sleeved at the bottom end of the limiting rod. The bearing is arranged in a placement groove formed on the top surface of the bottom plate.

[0009] In a specific embodiment, the clamping component includes a clamping seat fixedly connected to the side surface of the connecting seat, and a sliding groove is formed on the side surface of the clamping seat. A slidable sliding frame is arranged inside the sliding groove. Limiting blocks are symmetrically fixed at the bottom end of the sliding frame, and a spring structure matching the limiting blocks is arranged on the inner bottom wall of the sliding groove.

[0010] In a specific embodiment, a cover plate is arranged on the side surface of the clamping seat, and jacks matching the clamping posts are formed on the side surfaces of the clamping seat and the cover plate.

[0011] In a specific embodiment, the spring structure includes a sleeve fixedly connected to the inner bottom wall of the sliding groove, a spring is arranged inside the sleeve, and a sliding rod is fixedly connected to the top surface of the spring.

[0012] In a specific embodiment, grooves are formed on both sides of the connector head, and anti-slip patterns for increasing friction are arranged inside the grooves.

[0013] Compared with the prior art, the utility model provides a one-piece connector with secondary locking, and has the following beneficial effects:

[0014] In the technical solution disclosed by the utility model, when the connector head is inserted into the inside of the connecting seat, the clamping block on the top surface of the connector head enters above the bottom plate, and the clamping plate is rotated to squeeze and fix the clamping block to complete the preliminary locking. Furthermore, the sliding frame is pinched to compress the spring structure and drive the limiting block to contract. The clamping post installed on the side plate of the connector head is inserted into the inside of the clamping seat. The sliding frame is released, and its reset drives the limiting block to insert into the inside of the clamping post to complete the secondary locking, which plays a role in increasing the service life of the self-locking structure and avoiding the self-locking failure caused by the lack of material elasticity.

[0015] Through the connection component and the clamping component provided by the present utility model, when the connector head is inserted into the connector socket, the clamping block fixed on the top surface of the connector head moves along, and is lapped on the top surface of the bottom plate. Rotate the clamping plate to cover the top surface of the clamping block. When the limiting rod is screwed and rotates through the bearing, the clamping plate is limited and locked, so as to achieve the preliminary locking of the connector head. Further, the clamping post installed on the side plate of the connector head moves along. At the same time, pinch the sliding frame to drive the limiting block fixed on its surface to move downward inside the sliding groove and squeeze the spring below the sliding rod. The clamping post enters the inside of the socket through the jack. Release the sliding frame, and the spring rebounds, driving the sliding rod on the top surface to lift the sliding frame. The limiting block fixed on the surface of the sliding frame is inserted into the hole reserved on the surface of the clamping post to limit and fix the clamping post, so that the connector head is locked for the second time, thereby achieving the effect of improving the service life of the self-locking structure of the connector and avoiding the influence on the self-locking effect due to the attenuation of the material elasticity.

Detailed Embodiments

[0022] The following will cooperate with the drawings and embodiments to detail the implementation manners of the present application, so as to fully understand how the present application uses technical means to solve technical problems and achieve the realization process of technical effects and implement accordingly.

[0023] Figures 1 - 4This is an embodiment of the present utility model. A one-piece connector with secondary locking includes a connector head 1. One end of the connector head 1 is inserted with a connector seat 2. The top surface of the connector head 1 is symmetrically provided with clamping blocks 3, and a connection assembly 4 is clamped on the surface of the clamping blocks 3. The two sides of the connector seat 2 are symmetrically provided with clamping assemblies 5, and a clamping post 6 is clamped inside the clamping assemblies 5. The clamping post 6 is installed on the side surface of the connector head 1 through a side plate 7 sleeved at one end.

[0024] The specific problem addressed by this specific embodiment is as follows: When using a material with its own elasticity to achieve the locking and unlocking of the secondary lock, after long-term use, the self-locking structure will fail due to the loss of material elasticity. This solution has a limited service life for the self-locking structure. In the present utility model, when the connector head 1 is inserted into the inside of the connector seat 2, the clamping block 3 on the top surface of the connector head 1 enters above the bottom plate 41, and the clamping plate 44 is rotated to squeeze and fix the clamping block 3 to complete the preliminary locking. Furthermore, the sliding frame 52 is pinched to compress the spring structure 54 and drive the limiting block 53 to contract. The clamping post 6 installed on the side surface of the connector head 1 through the side plate 7 is inserted into the inside of the clamping seat 51. The sliding frame 52 is released, and its reset drives the limiting block 53 to be inserted into the inside of the clamping post 6 to complete the secondary locking, which plays a role in increasing the service life of the self-locking structure and avoiding self-locking failure caused by the loss of material elasticity.

[0025] The connecting component 4 includes a bottom plate 41 fixedly connected to the top surface of the connecting seat 2, and vertical plates 42 are symmetrically arranged on the top surface of the bottom plate 41. A rotating rod 43 is arranged inside the vertical plate 42, and a rotatable clamping plate 44 is arranged on the surface of the rotating rod 43. A sleeve hole is formed on the surface of the clamping plate 44, and a limiting structure 45 is arranged inside the sleeve hole; the clamping component 5 includes a clamping seat 51 fixedly connected to the side surface of the connecting seat 2, and a sliding groove is formed on the side surface of the clamping seat 51. A slidable sliding frame 52 is arranged inside the sliding groove. Symmetrically fixed to the bottom end of the sliding frame 52 are limiting blocks 53, and a spring structure 54 matching the limiting blocks 53 is arranged on the inner bottom wall of the sliding groove. In this specific embodiment, the limiting structure 45 includes a limiting rod 451 sleeved inside the hollow part and capable of rotating, and a bearing 452 is sleeved at the bottom end of the limiting rod 451. The bearing 452 is arranged in a placement groove formed on the top surface of the bottom plate 41; the spring structure 54 includes a sleeve 541 fixedly connected to the inner bottom wall of the sliding groove, and a spring 542 is arranged inside the sleeve 541. A sliding rod 543 is fixed to the top surface of the spring 542. When the connector head 1 is inserted into the connecting seat 2, the clamping block 3 fixed to the top surface of the connector head 1 moves along with it and overlaps on the top surface of the bottom plate 41. Rotate the clamping plate 44 to cover the top surface of the clamping block 3. When the limiting rod 451 is screwed and rotates through the bearing 452, the clamping plate 44 is limited and locked, so as to achieve the preliminary locking of the connector head 1. Furthermore, the clamping column 6 installed on the side surface of the connector head 1 through the side plate 7 moves along with it. At the same time, hold the sliding frame 52 and make the limiting block 53 fixed to its surface move downward inside the sliding groove and squeeze the spring 542 below the sliding rod 543. The clamping column 6 enters the inside of the clamping seat 51 through the jacking hole. Release the sliding frame 52, and the spring 542 rebounds, driving the sliding rod 543 on the top surface to lift the sliding frame 52. The limiting block 53 fixed to the surface of the sliding frame 52 is inserted into the hole reserved on the surface of the clamping column 6 to limit and fix the clamping column 6, so that the connector head 1 is locked for the second time, thereby achieving the effect of improving the service life of the self-locking structure of the connector and avoiding the influence on the self-locking effect due to the attenuation of the elasticity of its material.

[0026] In this specific embodiment, grooves are formed on both sides of the connector head 1, and anti-slip patterns for increasing friction are arranged inside the grooves;

[0027] The grooves arranged on the surface of the connector head 1 and the protrusions on the side surface of the grooves can reduce the contact area with the fingers, increase the pressure and friction, and avoid the situation of dropping the hand when pulling out the connector head 1.

[0028] The control mode of the present invention is automatically controlled by a controller. The control circuit of the controller can be realized by simple programming of those skilled in the art. The provision of power also belongs to the common knowledge in the art. And the present invention is mainly used to protect mechanical devices, so the control mode and circuit connection of the present invention will not be explained in detail.
