Description

Technical Field

[0001] This utility model relates to the field of sealing joint technology, and in particular to a sealing joint that prevents rotation. Background Technology

[0002] A sealing joint is a sealing device used at pipe connections. It is mainly used to ensure the sealing performance of pipe connections and prevent fluid leakage and gas penetration. A sealing joint consists of a sleeve and a sealing ring, which is generally made of rubber.

[0003] To facilitate operation by construction personnel, the outer wall of the sealing joint is often designed in a shape that facilitates rotation under force, such as an outer ring structure similar to a hexagonal nut or a convex ring with grooves. Although the above structures facilitate rotation under force, they may be subject to deflection forces during use, which may cause the sealing joint to rotate. This may reduce the sealing strength of the sealing joint. Therefore, a sealing joint that prevents rotation is needed to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide a sealing joint that prevents rotation, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an anti-rotation sealing joint, comprising:

[0022] 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.

[0023] This utility model provides, for example Figure 1-4 The anti-rotation sealing joint shown includes a joint body 1, a sealing ring 2 in the inner cavity of the joint body 1, the sealing ring 2 serves to seal, a connecting pipe 3 is provided on the back of the joint body 1, and an anti-rotation mechanism 4 is sleeved on the outside of the joint body 1 to prevent the sealing joint from rotating due to deflection force.

[0024] The anti-rotation mechanism 4 includes an annular groove formed on the outer wall of the connector body 1. A rotating ring 401 and a moving ring 406 are provided within the inner cavity of the annular groove. The back of the moving ring 406 is rotatably connected to the front of the rotating ring 401. Limiting grooves are symmetrically formed on the inner wall of the annular groove. Limiting sliders 407 are slidably fitted into the inner cavities of both limiting grooves. The limiting grooves and limiting sliders 407 ensure smooth movement of the moving ring 406 and the rotating ring 401. The two limiting sliders 407 are symmetrically and fixedly connected to the inner wall of the moving ring 406. A return spring 405 is provided on the front of the rotating ring 401. The return spring 405 can undergo elastic deformation, thereby causing the rotating ring 401 and the moving ring 406 to automatically perform a return motion. The return spring 405 is fixedly connected between the moving ring 406 and the annular groove. The wall sleeve is provided with an outer sleeve 402. The outer wall of the rotating ring 401 is fixedly connected to the inner wall of the outer sleeve 402. The back of the outer sleeve 402 is provided with a movable ring 403, which is fixedly connected to the back of the outer sleeve 402. The front of the movable ring 403 is provided with multiple insertion holes in a ring array. The back of the connector body 1 is provided with multiple insertion rods 404 in a ring array. The number of insertion rods 404 and insertion holes can be changed according to actual needs. When the insertion rod 404 is inserted into the insertion hole, the outer sleeve 402 and the movable ring 403 can drive the connector body 1 to rotate. Normally, under the action of the return spring 405, the insertion rods 404 and insertion holes are always in a separated state. Multiple insertion rods 404 are fixedly connected to the back of the connector body 1. The outer wall of multiple insertion rods 404 is movably sleeved with the inner cavity of the corresponding insertion hole.

[0025] A partition tube 5 is fixedly connected to the back of the connector body 1. The partition tube 5 protects the connecting tube 3. The outer wall of the partition tube 5 is movably sleeved with the inner cavity of the movable ring 403.

[0026] The outer wall of the outer sleeve 402 is fixedly fitted with a six-sided force-applying ring 6, which is similar to the outer ring structure of a hexagonal nut. It is used to facilitate the application of force by construction personnel to drive the outer sleeve 402 and the movable ring 403 to move. The inner wall of the six-sided force-applying ring 6 is fixedly fitted with the outer wall of the movable ring 403.

[0027] Working principle of this utility model:

[0028] When the sealing joint does not need to be rotated but the outer sleeve 402, movable ring 403, and six-sided force ring 6 are subjected to a deflection force, the insertion rod 404 is not inserted into the insertion hole under the action of the return spring 405. Therefore, the outer sleeve 402, movable ring 403, and six-sided force ring 6 cannot drive the joint body 1 to rotate. It can only be automatically activated by rotating the ring 401. When the sealing joint needs to be rotated, a force is applied to the outer sleeve 402, movable ring 403, and six-sided force ring 6, causing the outer sleeve 402, movable ring 403, and six-sided force ring 6 to drive the insertion hole towards the insertion rod 404. When the insertion rod 404 is inserted into the insertion hole and the movable ring 403 and six-sided force ring 6 can no longer move towards the sealing ring... 2. When moving, the outer sleeve 402, the movable ring 403, and the six-sided force ring 6 can be rotated to drive the connector body 1 to rotate. After the rotation is completed, the force applied to the outer sleeve 402, the movable ring 403, and the six-sided force ring 6 is removed. The outer sleeve 402, the movable ring 403, and the six-sided force ring 6 will automatically perform a reset movement under the action of the reset spring 405. The plug rod 404 will separate from the plug hole again. At this time, it will not be able to drive the connector body 1 to rotate. This achieves the purpose of driving the sealing connector to rotate only after the plug rod 404 is inserted into the plug hole with force. This effectively avoids the rotation of the sealing connector due to the deflection force and ensures the sealing strength of the sealing connector.

[0029] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model 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 utility model should be included within the protection scope of the present utility model.
