Description

Technical Field

[0001] The utility model belongs to the technical field of ferrule, and specifically relates to a ferrule structure with high stability. Background Art

[0002] There are various types of ferrules. Among them, the ferrule used for pipe fitting connection is a relatively common component. When connecting pipe fittings, not only does the ferrule need to have good stability, but also certain sealing performance. When the existing ferrule is connected to a pipe fitting, a threaded connection structure is usually adopted. Although the threaded connection can improve the connection stability to a certain extent, the ferrule is prone to looseness under the influence of the fluid movement in the pipe fitting, and even fall off during long-term use, affecting the connection firmness and sealing performance of the pipe fitting, and then causing fluid leakage, with poor use effect. Therefore, this application proposes a ferrule structure with high stability. Content of the Utility Model

The deformable sealing ring and the flexible sealing clamping ring are respectively fixedly connected to both sides of the sealing gasket, and the flexible sealing clamping ring is clamped and connected with the annular groove.

[0008] Preferably, the sealing gasket, the deformation sealing ring and the flexible sealing clamping ring are of an integral structure. The cross-section of the sealing gasket is a rectangular structure, and the cross-sections of the deformation sealing ring and the flexible sealing clamping ring are both arc-shaped structures.

[0009] Preferably, both the first limiting component and the second limiting component are composed of an L-shaped deformable metal support, a plurality of limiting teeth and an elastic support body.

[0023] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments; based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0024] Provided by Figures 1 to 4 a high-stability ferrule structure of the present utility model includes a ferrule body 1 and a first pipe fitting 2 and a second pipe fitting 3 that match it. The ferrule body 1 is connected between the first pipe fitting 2 and the second pipe fitting 3. A convex ring 4 is fixedly arranged at the middle position of the inner side wall of the ferrule body 1. One end of the convex ring 4 is provided with a first sealing ring 5 and several first limiting components 6. The other end of the convex ring 4 is provided with a second sealing ring 7 and several second limiting components 8. First internal threads 9 and second internal threads 10 are respectively arranged at both ends of the inner surface of the ferrule body 1. External threads 11 that match the first internal threads 9 and the second internal threads 10 are arranged at one ends of the outer surfaces of the first pipe fitting 2 and the second pipe fitting 3. Limiting rings 12 are fixedly arranged at one ends of the first pipe fitting 2 and the second pipe fitting 3 close to the ferrule body 1. Several annular limiting grooves 13 that match the first limiting components 6 and the second limiting components 8 are opened on the arc-shaped outer surfaces of the limiting rings 12;

[0025] During use, connect the ferrule body 1 between the first pipe fitting 2 and the second pipe fitting 3. The threaded connection is achieved through the cooperation of the first internal thread 9, the second internal thread 10 and the external thread 11. The sealing performance of the connection is improved through the first sealing ring 5 and the second sealing ring 7. The limiting function is realized through the first limiting component 6 and the second limiting component 8, preventing the ferrule body 1 from loosening during use;

[0026] As shown by Figures 1 to 7 In the middle position of the outer surface of the ferrule body 1, a hexagonal groove 14 is provided. Ring-shaped grooves 15 matching the first sealing ring 5 and the second sealing ring 7 are provided at both ends of the convex ring 4. The cross-section of the ring-shaped groove 15 is an arc structure. Both the first sealing ring 5 and the second sealing ring 7 are composed of a sealing gasket 16, a deformable sealing ring 17 and a flexible sealing clamping ring 18. The deformable sealing ring 17 and the flexible sealing clamping ring 18 are respectively fixedly connected to both sides of the sealing gasket 16. The flexible sealing clamping ring 18 is snap-fitted with the ring-shaped groove 15. The sealing gasket 16, the deformable sealing ring 17 and the flexible sealing clamping ring 18 are of an integral structure. The cross-section of the sealing gasket 16 is a rectangular structure, and the cross-sections of the deformable sealing ring 17 and the flexible sealing clamping ring 18 are both arc structures. Both the first limiting component 6 and the second limiting component 8 are composed of an L-shaped deformable metal support 19, a number of limiting teeth 20 and an elastic support 21. The L-shaped deformable metal support 19 is welded to the ferrule body 1 and the convex ring 4. The limiting teeth 20 are fixedly connected to one side of the L-shaped deformable metal support 19 and match the annular limiting groove 13. The elastic support 21 is fixedly connected to the other side of the L-shaped deformable metal support 19 and fits against the inner wall of the ferrule body 1;

[0027] The ferrule body 1 can be tightened by using a wrench through the hexagonal groove 14. During installation, the flexible sealing clamping ring 18 is installed into the internal of the ring-shaped groove 15 to achieve limiting. After installation, the end face of the limiting ring 12 applies pressure to the deformable sealing ring 17, causing the deformable sealing ring 17 to deform, thereby improving the sealing performance. During the installation process, the limiting teeth 20 are in contact with the outer surface of the limiting ring 12. At this time, the resistance will cause the L-shaped deformable metal support 19 to deform. When the limiting teeth 20 are snap-fitted with the annular limiting groove 13, the L-shaped deformable metal support 19 resets. At this time, the elastic support 21 can apply pressure to the L-shaped deformable metal support 19. The limiting function is formed through the cooperation of the limiting teeth 20 and the annular limiting groove 13. Even if the ferrule body 1 is affected by fluid impact or vibration, loosening or falling off can be avoided. During disassembly, only rotate the ferrule body 1 forcefully.

[0028] During work, by setting a first internal thread, a second internal thread, and an external thread, the ferrule body can be threadedly connected to the first pipe fitting and the second pipe fitting, improving the connection stability. By setting a limiting ring, an annular limiting groove, and a first limiting component and a second limiting component composed of an L-shaped deformed metal support, a number of limiting teeth, and an elastic support body, it is possible to achieve tensile limiting of the connection between the ferrule body and the first pipe fitting and the second pipe fitting, avoiding loosening of the ferrule body and the first pipe fitting and the second pipe fitting due to vibration, and improving the connection stability; by setting a first sealing ring and a second sealing ring composed of a sealing gasket, a deformed sealing ring, and a flexible sealing clamping ring, it is possible to efficiently seal the connection between the ferrule body and the first pipe fitting and the second pipe fitting, avoiding fluid leakage. By setting an annular groove, it is possible to limit the first sealing ring and the second sealing ring during assembly, improving the convenience of assembly.
