Description

Technical Field

[0001] The utility model relates to the technical field of sewage pipe connection, in particular to a PVC-UH sewage pipe connection rubber ring. Background Art

[0002] PVC-UH pipes have high strength, high pressure bearing capacity, good ring stiffness, and excellent impact resistance. This type of pipe is suitable for installation and laying in pipe corridors. Its structural design allows the pipe to release material stress under temperature changes. PVC-UH pipes also have a long service life and are usually used in water supply and drainage systems. During the connection and use of PVC pipes, rubber rings are used to seal the joints to prevent water leakage. With the development of technology, the function and structure of rubber rings are constantly being upgraded to better meet the needs of use.

[0003] In view of this, Chinese patent number CN215674185U proposes a PVC-UH sewage pipe connecting rubber ring. The utility model can tighten the inner surface of one end of the rubber ring through a tightening device, so that the outer surface of the rubber ring can be in close contact with the inner surface of the sewage pipe, thereby improving the sealing of the connection between the sewage pipes. However, when the existing connecting rubber ring is used, due to its thin thickness, when connecting pipes of different connection lengths, if the contact is not sufficient, it will affect the sealing of the overall connection. Therefore, a buffer-type connecting rubber ring structure is needed. Utility Model Content

[0004] In order to solve the above problems, the purpose of the utility model is to provide a PVC-UH sewage pipe connecting rubber ring to solve the problems raised in the above background technology.

[0005] To achieve the above-mentioned purpose, the utility model proposes a PVC-UH sewage pipe connecting rubber ring, comprising three first rubber rings, wherein a buffer-type connecting mechanism is arranged between the three first rubber rings;

[0006] The buffer connection mechanism includes a rubber shaft fixed between three first rubber rings at equal distances, and the two ends of each rubber shaft are respectively fixedly connected to one side of each first rubber ring, the inner wall of each rubber shaft is provided with a first buffer groove, the inner wall of each first buffer groove is fixedly provided with a spring, the inner wall of each first rubber ring is provided with a plurality of second buffer grooves at equal distances, and a support ring is fixedly provided on one side of one of the first rubber rings.

[0007] In one example, a second rubber ring is fixedly provided on one side of the support ring, and a third buffer groove is formed on an inner wall of the second rubber ring.

[0008] In one example, a sealing ring is fixedly provided on one side of the inner wall of each of the first rubber rings, and a fourth buffer groove is opened at one end of the inner wall of each of the sealing rings.

[0009] In one example, a filling groove is formed at the other end of the inner wall of each sealing ring.

[0010] In one example, a metal ring is inserted into the inner wall of each of the filling slots.

[0011] In one example, a protective pad is fixedly provided on one side of one of the first rubber rings.

[0012] The PVC-UH sewage pipe connecting rubber ring proposed by the utility model can bring the following beneficial effects:

[0013] 1. The PVC-UH sewage pipe connecting rubber ring is supported by the bottom support ring, so that the rubber ring is not easy to deform when it is installed, and when connecting sewage pipes of different lengths, because the rubber ring is composed of three first rubber rings through a rubber shaft, when the sewage pipe squeezes the rubber ring, the three first rubber rings will squeeze the rubber shaft, and a first buffer groove is opened inside the rubber shaft, in which a spring is arranged and will be squeezed and deformed, so that the first rubber rings are overlapped together, which is convenient for sealing when sewage pipes of different lengths are connected, and at the same time, the tightness of the seal is increased, and the sealing effect of the device is improved.

[0014] 2. This PVC-UH sewage pipe connecting rubber ring, when installing the rubber ring, is put on the upper end of one of the sewage pipes, and contacts the pipe through multiple sealing rings inside it, so that the area in contact with it is sealed. At the same time, a fourth buffer groove is opened inside the sealing ring to make it softer and better fit with the pipe. At the same time, a filling groove is opened at the contact end, in which a metal ring is filled, so that it is not easy to fold, and the contact area is increased, thereby improving the sealing of the device.
