Description

Technical Field

[0001] The utility model relates to the technical field of sealing rings, in particular to a sealing ring for a pipe fitting connector. Background Art

[0002] When pipe fittings are butted, there are many butting methods. For thin-walled pipe fittings and those that are not convenient to process threads at the ends, special connectors are often required for connection. For example, a Chinese patent with the authorized announcement number CN203431341U discloses a movable connector for sanitary pipes, in which a sealing ring is squeezed by pipe fitting one and pipe fitting two to make a sealed connection between pipe fitting one and pipe fitting two. However, during the process of squeezing and locking pipe fitting one and pipe fitting two, the sealing ring is prone to irregular deformation, resulting in incomplete contact between the pipe fitting and the sealing ring. When the air pressure or water pressure in pipe fitting one and pipe fitting two is too high, the sealing ring is also prone to displacement and detachment from the sealing groove, affecting the sealing performance of the sealing ring. Summary of the Utility Model

[0003] The purpose of the utility model is to provide a sealing ring for a pipe fitting connector aiming at the above deficiencies, which can effectively prevent the incomplete contact between the pipe fitting and the sealing ring caused by extrusion and ensure the sealing performance of the sealing ring.

[0004] To achieve the above purpose, the utility model adopts the following technical scheme:

[0005] A sealing ring for a pipe fitting connector includes a sealing ring main body. The left end face and the right end face of the sealing ring main body are respectively provided with abutting protrusions. An anti-detachment structure is arranged inside the sealing ring main body, and the anti-detachment structure is used to prevent the sealing ring main body from detaching from the pipe fitting after extrusion.

[0006] Further, an inner annular cavity and an outer annular cavity are coaxially arranged inside the sealing ring main body; the inner annular cavity and the outer annular cavity are used to install the anti-detachment structure.

[0007] Further, the anti-detachment structure includes an inner right annular plate and an inner left annular plate arranged at the bottom end and the top end of the inner annular cavity, an outer right annular plate and an outer left annular plate arranged at the bottom end and the top end of the outer annular cavity, an inner spring arranged inside the inner annular cavity, and an outer spring arranged inside the outer annular cavity. The starting end and the ending end of the inner spring are respectively connected to the inner right annular plate and the inner left annular plate, and the starting end and the ending end of the outer spring are respectively connected to the outer right annular plate and the outer left annular plate.

[0008] Further, the inner annular cavity and the outer annular cavity are separated by a butting ring, and the abutting protrusion is arranged at the end facing the butting ring.

[0009] Furthermore, the sealing ring body includes a connecting portion, a supporting portion detachably connected to the connecting portion, the abutting protrusion is provided on the connecting portion, the anti-disengagement structure is provided on the supporting portion, and one end of the abutting ring is bonded to the supporting portion.

[0010] The beneficial effects of the present utility model are as follows:

[0011] In practical applications, when the abutting protrusion is aligned with the sealing groove on the pipe fitting, after the two pipe fittings are tightened, the anti-disengagement structure prevents the sealing ring body after extrusion from disengaging from the pipe fitting, ensuring the sealing performance of the sealing ring body; the present utility model can effectively prevent the situation where the pipe fitting and the sealing ring are not in complete contact due to extrusion, ensuring the sealing performance of the sealing ring.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0017] As Figure 1 , Figure 2 , Figure 3 and Figure 4 shown, a pipe fitting connector sealing ring includes a sealing ring body 1. The left end face and the right end face of the sealing ring body 1 are respectively provided with abutting protrusions 11. An anti-disengagement structure is arranged inside the sealing ring body 1, and the anti-disengagement structure is used to prevent the sealing ring body 1 after extrusion from disengaging from the pipe fitting.

[0018] During use, when the abutting protrusions 11 are aligned with the sealing grooves on the pipe fitting, after the two pipe fittings are tightened, the anti-disengagement structure prevents the sealing ring body 1 after extrusion from disengaging from the pipe fitting, ensuring the sealing performance of the sealing ring body 1; the present utility model can effectively prevent the situation where the pipe fitting and the sealing ring are not in complete contact due to extrusion, ensuring the sealing performance of the sealing ring.

[0019] As Figure 1, Figure 2 , Figure 3 and Figure 4 As shown in Figure 2 , Figure 3 and Figure 4 , an inner annular cavity 12 and an outer annular cavity 13 are coaxially arranged inside the sealing ring body 1; the inner annular cavity 12 and the outer annular cavity 13 are used for installing the anti-disengagement structure; in this embodiment, the anti-disengagement structure is installed through the inner annular cavity 12 and the outer annular cavity 13.

[0020] As Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown in Figure 1 , Figure 2 , Figure 3 and Figure 4 , the anti-disengagement structure includes an inner right annular plate 21 and an inner left annular plate 22 arranged at the bottom end and the top end of the inner annular cavity 12, an outer right annular plate 23 and an outer left annular plate 24 arranged at the bottom end and the top end of the outer annular cavity 13, an inner spring 25 arranged inside the inner annular cavity 12, and an outer spring 26 arranged inside the outer annular cavity 13. The starting end and the ending end of the inner spring 25 are respectively connected to the inner right annular plate 21 and the inner left annular plate 22, and the starting end and the ending end of the outer spring 26 are respectively connected to the outer right annular plate 23 and the outer left annular plate 24; in this embodiment, during the process of the two pipe fittings being pressed tightly, the inner spring 25 and the outer spring 26 are compressed. After the two pipe fittings are pressed tightly, the inner right annular plate 21 and the inner left annular plate 22 are driven by the restoring force of the inner spring 25 to press tightly against the two pipe fittings, and the outer right annular plate 23 and the outer left annular plate 24 are driven by the restoring force of the outer spring 26 to press tightly against the two pipe fittings, avoiding the situation that the pipe fittings are not in complete contact with the sealing ring due to extrusion.

[0021] As Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown in Figure 1 , Figure 2 , Figure 3 and Figure 4 , the inner annular cavity 12 and the outer annular cavity 13 are separated by a butting ring 27, and the butting protrusion 11 is arranged at the end of the butting ring 27; in this embodiment, when the butting protrusion 11 is arranged at the end of the butting ring 27, the sealing ring body 1 is more evenly stressed during extrusion, further preventing the butting protrusion 11 from disengaging from the sealing groove of the pipe fitting.

[0022] As Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown in Figure 1 , Figure 2 , Figure 3 and Figure 4 , the sealing ring body 1 includes a connecting portion 101, a supporting portion 102 detachably connected to the connecting portion 101. The butting protrusion 11 is arranged on the connecting portion 101, the anti-disengagement structure is arranged on the supporting portion 102, and one end of the butting ring 27 is bonded to the supporting portion 102; in this embodiment, when the sealing ring body 1 includes the connecting portion 101 and the supporting portion 102, the supporting portion 102 is sleeved on the connecting portion 101, the manufacturing process is simpler, and the production cost of the sealing ring body 1 is reduced.
