Description

A sealing ring for connecting a drain pipe and a pipe clamp

technical field

The utility model belongs to the technical field of electrical accessories, in particular to a sealing ring used for connecting a drainage pipe and a pipe clamp.

Background technique

In some existing electrical appliances, such as washing machines, dishwashers and other electrical appliances, there are drain pipes, some of the drain pipes are installed with pipe clamps, and the pipe clamps are fixedly provided with water nozzles that communicate with the drain pipes. In order to lift the pipe clamps For the sealing performance with the drain pipe, an O-ring seal will be set between the pipe clamp and the drain pipe. Because the outer end of the drain pipe is curved, the existing O-ring seal is not tight with the drain pipe and the pipe clamp. , resulting in poor sealing performance, which may lead to water leakage, especially when the pipe body is softened and the risk of water leakage is higher when using warm water.

SUMMARY OF THE INVENTION

Aiming at the disadvantages of poor sealing performance between the sealing ring, the drainage pipe and the pipe clamp in the prior art, the utility model provides a sealing ring for connecting the drainage pipe and the pipe clamp, and the sealing ring can be relatively tight with the drainage pipe , and set a stepped groove, which can significantly improve the sealing performance.

The purpose of the invention of the present utility model is achieved through the following technical solutions: a sealing ring for connecting a drain pipe and a pipe clamp, comprising a ring body with a ring structure, and a concave step groove is provided on one side of the ring body, and the step groove The ring body is coaxially arranged with the through hole in the middle of the ring body, and there is a stepped surface facing the step groove between the step groove and the through hole; the side of the ring body with the step groove is the front side, and the ring body is formed from the middle The position to both sides is bent towards the front of the ring body so that the front of the ring body is an arc-shaped structure.

In the above scheme, the front of the ring body is arranged in an arc-shaped structure, which can better fit the outer surface of the drain pipe, and the water nozzle on the drain pipe is embedded in the stepped groove, which is equivalent to an additional sealing protection, which can improve the sealing effect. performance.

Preferably, the front surface of the ring body is a circular arc surface.

Preferably, the through hole in the middle of the ring body is a circular hole.

Preferably, the diameter of the through hole is greater than 2.5 mm. The inner diameter of the water return nozzle on the conventional pipe clamp is 2.5mm, and the diameter of the through hole on the ring body is set to be larger than 2.5mm, which will not affect the water flow.

Preferably, the side surface of the ring body without the step groove is a reverse side, and the reverse side of the ring body is also an arc-shaped structure. In this way, the reverse side of the ring body can better fit with the pipe clamp, so that the sealing performance can be improved.

Preferably, the stepped groove is a circular groove.

Preferably, the ring body is made of rubber material. The sealing ring made of rubber has certain elasticity and better sealing performance.

Compared with the prior art, the utility model has the following beneficial effects: the utility model has a simple structure and good sealing performance.

Detailed ways

The present utility model will be further described below in conjunction with the embodiments represented by the accompanying drawings:

Example 1

As shown in Figures 1 and 2, a sealing ring for connecting a drain pipe and a pipe clamp 6 includes a ring body 1 with an annular structure, the ring body 1 is made of rubber material, and the middle position of the ring body 1 is The through hole 2 is a circular hole, the diameter of the through hole 2 is 3mm, and one side of the ring body 1 is provided with a concave stepped groove 3, the stepped groove 3 is a circular groove, and the stepped groove 3 is located in the middle of the ring body 1. The through hole 2 of the ring body 2 is coaxially arranged, and a step surface 4 is arranged between the step groove 3 and the through hole 2 towards the step groove 3; the side of the ring body 1 with the step groove 3 is the front side, and the ring body 1 is bent toward the front of the ring body 1 from the middle position to both sides, so that the front of the ring body 1 has a circular arc surface structure. The side surface of the ring body 1 without the step groove 3 is the reverse side, and the reverse side of the ring body 1 is also an arc-shaped structure.

As shown in FIG. 3 , the sealing ring is arranged between the drain pipe 5 and the pipe clamp 6 , the water nozzle 7 on the drain pipe 5 is embedded in the stepped groove 3 , and the front surface of the ring body 1 and the outer surface of the drain pipe 5 can fit relatively well. Tight, the reverse side of the ring body 1 and the pipe clamp 6 can fit more closely, which can significantly improve the sealing performance between the drain pipe 5 and the pipe clamp 6 .

The specific embodiments described herein are merely illustrative of the spirit of the present invention. Those skilled in the art of the present invention can make various modifications or supplements to the described specific embodiments or replace them in similar ways, but will not deviate from the spirit of the present invention or go beyond the appended claims the defined range.
