Description

Technical Field

[0001] This utility model relates to the field of rubber sealing ring technology, specifically an adjustable rubber sealing ring suitable for different pipe diameters. Background Technology

[0002] A rubber seal is a ring-shaped sealing element made of elastic material (mainly rubber) used to prevent liquid or gas leakage or foreign matter from entering the contact surface of mechanical equipment. Its core function is to fill gaps through compression deformation. Rubber seals are usually installed in bearing rings or grooves, and fit tightly against the contact surface through elastic deformation. Common cross-sectional shapes include O-rings, rectangles, V-rings, and Y-rings.

[0003] In practical use, O-rings are the most common due to their simple structure, low cost, and wide applicability. When using O-rings, it is necessary to select the appropriate pipe diameter to better fit the bearing rings and other positions. Therefore, the sealing ring needs to ensure the sealing effect and adapt to different working environments. If it is difficult to adapt to different pipe diameters, it will directly affect the sealing effect of the sealing ring. Utility Model Content

[0004] The purpose of this invention is to provide an adjustable rubber sealing ring suitable for different pipe diameters, in order to solve the problem mentioned in the background art that the sealing ring needs to ensure sealing effect and adapt to different working environments. If it is difficult to adapt to different pipe diameters, the sealing effect of the sealing ring will be directly affected.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an adjustable rubber sealing ring suitable for different pipe diameters, comprising a main sealing ring, a first pipe diameter groove is provided at the center of the main sealing ring, a groove is provided on the main sealing ring at the edge of the first pipe diameter groove, secondary sealing rings are assembled on both sides of the main sealing ring, a second pipe diameter groove is provided at the center of the secondary sealing ring, and a protrusion is fixed on the side of the secondary sealing ring.

[0006] As a further technical solution of this utility model, the secondary sealing rings are symmetrically distributed about the central axis of the main sealing ring, and the inner diameter of the second pipe diameter groove is smaller than the inner diameter of the first pipe diameter groove.

[0007] As a further technical solution of this utility model, the grooves are distributed in a ring about the center of the main sealing ring, and the protrusions are distributed in a ring about the center of the secondary sealing ring.

[0008] As a further technical solution of this utility model, the groove and the protrusion are in a one-to-one correspondence, the protrusion is inserted into the inside of the groove, and the groove is filled with an adhesive layer for bonding and fixing.

[0009] As a further technical solution of this utility model, an anti-slip strip is fixed at the outward position of the side of the secondary sealing ring, and the anti-slip strip is protruding.

[0010] As a further technical solution of this utility model, a reserved cavity is formed in the secondary sealing ring, and a rubber reinforcing strip is fixedly filled in the reserved cavity. The reserved cavity and the rubber reinforcing strip have the same pattern.

[0011] Compared with the prior art, the beneficial effects of this utility model are: this adjustable rubber sealing ring suitable for different pipe diameters not only improves the opening adjustment capability, but also improves the strength and assembly convenience of the rubber sealing ring.

[0012] (1) By opening the first pipe diameter groove inside the main sealing ring and the second pipe diameter groove inside the secondary sealing ring, and opening grooves on both sides of the main sealing ring, and fixing protrusions on the side of the secondary sealing ring, the protrusions and grooves correspond one-to-one. Therefore, as needed, the secondary sealing ring can be assembled on both sides of the main sealing ring. At this time, a protrusion is inserted into the inside of a groove, and then the groove after insertion is filled with adhesive for connection and fixation. In this way, the original first pipe diameter groove can be narrowed into a second pipe diameter groove, and secondary sealing rings with different sizes of second pipe diameter grooves can be selected for assembly according to the actual situation, thereby improving the opening adjustment capability.

[0013] (2) A reserved cavity is formed inside the secondary sealing ring, and a rubber reinforcing strip is fixed inside the reserved cavity. The direction of the reserved cavity and the rubber reinforcing strip is the same as that of the secondary sealing ring, and the rubber reinforcing strip is I-shaped. Therefore, after the secondary sealing ring is assembled, its strength is improved to a certain extent, thereby ensuring the strength of the main sealing ring and the secondary sealing ring after they are used together.

[0014] (3) By fixing an anti-slip strip on the side of the secondary sealing ring, the anti-slip strip is located in the direction of the secondary sealing ring facing outwards and is protruding. Therefore, when assembling the secondary sealing ring, the protruding design of the anti-slip strip makes it easier for the operator to pick it up, making it easier for the staff to operate when assembling the secondary sealing ring and improving the assembly convenience.
