TECHNICAL FIELD

[0001] The utility model relates to the field of connector, concretely to a structure of preventing reverse screwing of lock ring. BACKGROUND

[0002] The problem of the connector lock ring product in the current market: the self-locking lock ring is easy to be reversed (when the product is assembled, the client is easy to reverse the lock ring from the rubber core in the subsequent operation).

[0003] Therefore, we propose a structure of preventing reverse screwing of lock ring to solve the above problems. CONTENT OF THE UTILITY MODEL

[0004] To solve the above technical problems, the utility model provides a structure of preventing reverse screwing of lock ring.

[0005] The structure of preventing reverse screwing of lock ring provided by the utility model includes rubber core, lock ring, spring and pin, the side wall of rubber core is equipped with spring containing groove, one end of rubber core opposite spring containing groove is equipped with installation groove, the connecting place of installation groove and spring containing groove on rubber core is detachably installed with pin, the inside of lock ring is equipped with driving part, and driving part is slidably connected in spring containing groove.

[0006] Preferably, the spring containing groove is in the shape of a circular arc.

[0007] Preferably, the driving part is equipped with first plane part and second plane part, and the first plane part and the second plane part are in contact with spring and pin respectively.

[0008] Preferably, the rubber core is equipped with round hole and semicircular hole matched with pin, and the semicircular hole is located at the end of pin.

[0009] Preferably, the side wall of pin is equipped with sawtooth pattern.

[0010] Compared with the related art, the structure of preventing reverse screwing of lock ring has the following beneficial effects:

[0011] Enhance safety: through the close cooperation between pin and the second plane part on the driving part of lock ring, the lock ring is effectively prevented from being reversed, so that the damage of equipment or security risks caused by misoperation or malicious destruction is avoided. This design significantly improves the safety of the overall structure.

[0012] Simplify installation and maintenance: the sawtooth pattern design of pin side wall makes the pin easily clamped in round hole and semicircular hole, which simplifies the installation process and reduces the installation difficulty. At the same time, this design is also convenient for subsequent maintenance and replacement work, which reduces the maintenance cost and time cost. DRAWINGS

[0019] The utility model will be further explained in connection with the drawings and embodiment.

[0020] Please combine with reference to Figures 1 to 5 A structure can prevent anti-twist lock ring, including glue core 2, lock ring 1, spring 3 and pin 4 and so on multiple components. In the structure, the lateral wall of glue core 2 is ingeniously provided with a spring accommodating groove 5, and the shape is arc-shaped, and the spring 3 that is also arc-shaped is perfectly adapted, to ensure that the spring can be stably placed and play its function.

[0021] At one end of glue core 2, the position opposite spring accommodating groove 5, design has an installation groove 6. This design makes the driving portion 7 of lock ring 1 can smoothly slide and be connected in spring accommodating groove 5. It is worth noting that the key position of connecting installation groove 6 and spring accommodating groove 5, adopts detachable pin 4 and fixes, this design not only enhances the flexibility of structure, also ensures the close cooperation between each component.

[0022] The driving portion 7 of lock ring 1 is specially provided with first plane portion 8 and second plane portion 9. First plane portion 8 is in close contact with spring 3, when lock ring 1 rotates, it is just through this plane portion to push spring 3 and compress. And when lock ring 1 stops rotating, spring 3 then pushes first plane portion 8, makes lock ring 1 reset, to realize its rotating function. And second plane portion 9 then cooperates with pin 4, when pin 4 is assembled in place, it effectively blocks second plane portion 9, to prevent lock ring 1 from being anti-twisted.

[0023] In order to more smoothly install the pin 4, the rubber core 2 is specially provided with a round hole 10 and a semicircular hole 11 matched with the pin 4. The semicircular hole 11 is ingeniously located at the end of the pin 4, which greatly facilitates the installation of the pin. The sidewall of the pin 4 is specially designed with a sawtooth pattern 12, which makes the pin easily clamped when inserted into the round hole 10 and the semicircular hole 11, thereby enhancing the stability of the connection and avoiding the risk of breaking the hole.

[0024] The specific installation process is also very simple: first, insert the pin 4 into the round hole 10; then, install the spring 3; then, put the lock ring 1 on the rubber core 2 and rotate the lock ring 1, so that the driving part 7 is smoothly moved into the spring containing groove 5 along the installation groove 6; finally, the end of the pin 4 is ingeniously inserted into the semicircular hole 11 by means of a tool. In this way, the lock ring 1 is firmly fixed and cannot be untwisted. The whole design not only has compact structure and perfect function, but also has simple installation, flexible operation, which greatly improves the convenience and safety of use.

[0025] The above is only an embodiment of the present application, and does not limit the patent range of the present application. Any equivalent structure or equivalent process transformation, or direct or indirect application in other related technical fields, which is based on the content of the present application specification and drawings, is also included in the patent protection range of the present application.
