[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Please see Figure 1-3This utility model provides a technical solution: a connector connection locking structure, including a connector body 1. The outer walls of both sides of the insertion end of the connector body 1 are provided with a composite elastic clamping mechanism composed of an inner spring sheet 2 and an outer spring sheet 3. The outer spring sheet 3 is located outside the inner spring sheet 2 and the two are connected by several elastic connectors 4. The elastic connectors 4 are made of high-elasticity alloy steel with good elasticity and fatigue resistance. The connection points between the elastic connectors 4 and the inner spring sheet 2 and the outer spring sheet 3 are all fixed by welding. A buffer washer 5 is provided between the inner spring sheet 2 and the connector body 1. The buffer washer 5 is sleeved on the outside of the connector body 1 by adhesive. The buffer washer 5 and the inner spring sheet 2... The connection also employs an adhesive bonding method. The buffer gasket 5 is made of polyurethane material with excellent cushioning performance and durability. A dynamic connecting ring 7 is movably fitted onto the outer side of the connector body 1's insertion end. A retaining ring 8, fixedly fitted onto the outside of the connector body 1, is located on the outer side of the dynamic connecting ring 7. A tension spring 9, also fitted onto the outside of the connector body 1, connects the dynamic connecting ring 7 and the retaining ring 8. When the insertion end of the connector body 1 is inserted into the corresponding connection interface, the inner spring sheet 2 and the outer spring sheet 3, through the linkage of the elastic connector 4, effectively provide a uniform and continuous clamping force, ensuring tight contact between the connector body 1 and the interface. The buffer gasket 5 acts as a buffer between the inner spring sheet 2 and the connector body 1. This design reduces the impact of vibration or shock on internal components, protecting the overall structural stability. The dynamic connecting ring 7, under the synergistic action of the stabilizing ring 8 and the tension spring 9, can be flexibly adjusted to the optimal position according to actual needs. The secure connection at the corresponding connection interface edge further enhances the connector's adaptability and vibration resistance when facing external forces. Overall, the connector body 1 not only solves the problem of reduced clamping force caused by material fatigue and wear in traditional connectors, but also greatly improves the connector's stability and durability in high-vibration environments. It avoids loosening or even disconnection caused by frequent insertion and removal, extends the equipment's service life, and ensures stable operation for extended periods in complex working environments. Even after multiple insertion and removal operations, the connector body 1 maintains excellent contact performance, ensuring the reliability and durability of the device connection. Both the upper and lower ends of the inner spring sheet 2 have inwardly protruding portions 201, which are integral with the inner spring sheet 2. The inclination angle of the protruding portions 201 is between 15° and 45°. This structure enhances the clamping force on the connector body 1, ensuring the connector's firmness within the interface and reducing the risk of loosening due to vibration or external forces. Furthermore, when the connector body 1 is inserted into or removed from the corresponding connection interface, the protruding portions 201 allow the connector body 1 to smoothly guide the connector into the interface during insertion, while providing a secure locking effect after full insertion.The outer spring sheet 3 has a recessed slot in the middle of its outer wall, and several reinforcing ribs 301 are evenly welded and fixed on the inner wall of the recessed slot. Furthermore, several striped textures 302 are evenly distributed on the outer wall of the outer spring sheet 3. When the connector body 1 is inserted into the corresponding connection interface, the recessed slot in the middle of the outer wall of the outer spring sheet 3 interacts with the internal structure of the interface, providing additional clamping force and stability. The reinforcing ribs 301 enhance the structural strength of the outer spring sheet 3, preventing deformation during long-term use or repeated insertion and removal, ensuring a continuous and stable clamping effect. In addition, the outer wall of the outer spring sheet 3... Several striped textures 302 increase surface friction, further enhancing the tightness and stability between the outer spring sheet 3 and the interface, effectively preventing loosening caused by vibration or external force. Both sides of the stabilizing ring 8 have threaded holes through which clamping bolts 10 are inserted, and a round pressure block is welded to the end of the clamping bolt 10 facing the dynamic connecting ring 7. The dynamic connecting ring 7 is symmetrically provided with pressure-bearing slots 11 that match the structure of the round pressure blocks on the clamping bolts 10. When the clamping bolts 10 are tightened, the round pressure blocks at their ends can accurately embed into the pressure-bearing slots 11, providing a stable and uniform pressure distribution, ensuring the dynamic connection... The ring 7 fits snugly against the edge of the connection interface, which not only enhances the contact stability between the dynamic connection ring 7 and the connection interface, but also effectively prevents loosening or displacement caused by vibration or external forces. This ensures that the entire structure maintains high stability and vibration resistance in complex working environments. The center of the dynamic connection ring 7 is movably sleeved on the outside of the connector body 1, and several connection screw holes are arranged around the dynamic connection ring 7. These connection screw holes provide additional fixing points, allowing the dynamic connection ring 7 to be securely locked in the required position using bolts or other fasteners, thus enhancing the overall structure. To ensure stability and vibration resistance, both the inner spring sheet 2 and the outer spring sheet 3 are made of spring steel with high elasticity and good fatigue strength. Both the inner spring sheet 2 and the outer spring sheet 3 have an arc-shaped structure, with the area of ​​the outer spring sheet 3 being larger than that of the inner spring sheet 2. This structure allows the inner spring sheet 2 and the outer spring sheet 3 to better adapt to the shape of the connection interface and provide a uniformly distributed clamping force. Furthermore, because the area of ​​the outer spring sheet 3 is larger than that of the inner spring sheet 2, this not only increases the contact area and improves the overall clamping effect, but also effectively disperses stress and reduces wear or fatigue damage caused by excessive local pressure.

[0018] Working Principle: When using this connector to connect the locking structure, first align the connector body 1 with the corresponding connection interface and slowly insert it. As the outer spring sheet 3 contacts the inner wall of the connection interface, the striped texture 302 on its outer wall and the reinforcing ribs 301 in the recessed bayonet provide additional friction and structural strength. With further insertion, the outer spring sheet 3 and the inner spring sheet 2 are linked by the elastic connector 4, gradually applying a uniform and continuous clamping force. At this time, the protrusions 201 at both ends of the inner spring sheet 2 begin to contact the internal structure of the interface, smoothly guiding the connector body 1 into the interface. When the connector body 1 is fully inserted, the buffer washer 5 is located between the inner spring sheet 2 and the connector body 1, absorbing vibration and impact. Simultaneously... The dynamic connecting ring 7 is movably sleeved on the outside of the connector body 1. With the synergistic action of the retaining ring 8 and the tension spring 9, it can be flexibly adjusted to the optimal position according to actual needs and fit tightly against the edge of the connection interface. Next, by tightening the abutment bolts 10 on both sides of the retaining ring 8, the round pressure block at its end is precisely embedded in the pressure-bearing socket 11 on the dynamic connecting ring 7, further enhancing the contact stability between the dynamic connecting ring 7 and the connection interface. Finally, if it is necessary to further fix the position of the dynamic connecting ring 7, it can be firmly locked in the required position by bolts or other fasteners through several connecting screw holes surrounding it, ensuring that the entire connector system maintains high stability and vibration resistance in complex working environments, thereby completing a series of tasks.

[0019] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
