Description

Sealing ring for connecting drain pipe and pipe clamp

Technical Field

The utility model belongs to the technical field of electrical accessories, concretely relates to a sealing washer that is used for drain pipe and pipe clamp to be connected.

Background

In some current electrical apparatus, for example electrical apparatus such as washing machine, dish washer all are equipped with the drain pipe, install the pipe clamp on the partial drain pipe, fixed being equipped with the water injection well choke with the drain pipe intercommunication on the pipe clamp, in order to promote the sealing performance between pipe clamp and the drain pipe, can set up O type sealing washer between pipe clamp and drain pipe, because of the drain pipe outer end is the cambered surface, it is inseparable between current O type sealing washer and drain pipe and the pipe clamp, lead to sealing performance relatively poor, probably lead to leaking, the body softens the risk of leaking when especially warm water uses is higher.

Disclosure of Invention

The utility model discloses to the relatively poor drawback of sealing performance between sealing washer among the prior art and drain pipe, the pipe clamp, provide a sealing washer that is used for drain pipe and pipe clamp to be connected, this sealing washer can with the comparatively inseparable cooperation of drain pipe to set up a step groove, can show and promote sealing performance.

The invention aims to be realized by the following technical scheme: a sealing ring for connecting a drain pipe and a pipe clamp comprises a ring body with an annular structure, wherein an inwards concave step groove is formed in one side face of the ring body, the step groove and a through hole in the middle of the ring body are coaxially arranged, and a step surface arranged towards the step groove is arranged between the step groove and the through hole; the ring body is provided with a step groove, the side of the ring body provided with the step groove is the front side, and the ring body is bent from the middle position to the two sides towards the front side of the ring body, so that the front side of the ring body is of an arc-surface-shaped structure.

Among the above-mentioned scheme, set the front of circle body to the cambered surface shape structure, can more laminate with the surface of drain pipe, water injection well choke embedding step inslot on the drain pipe has been equivalent to one more sealed protection, can promote sealing 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 round hole.

Preferably, the diameter of the through hole is larger than 2.5 mm. The internal diameter of the water return nozzle on the conventional pipe clamp is 2.5mm, the diameter of the through hole on the ring body is set to be larger than 2.5mm, and the water flow cannot be influenced.

Preferably, the side surface of the ring body, on which the step groove is not formed, is a reverse surface, and the reverse surface of the ring body is also of an arc-shaped structure. The reverse side of the ring body can be better attached to the pipe clamp through the arrangement, so that the sealing performance can be improved.

Preferably, the stepped groove is a circular groove.

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

Compared with the prior art, the utility model discloses following beneficial effect has: the utility model discloses simple structure has good sealing performance.

Detailed Description

The invention will be further described with reference to the embodiments shown in the drawings to which:

example 1

As shown in fig. 1 and 2, a sealing ring for connecting a drain pipe with a pipe clamp 6 comprises a ring body 1 with an annular structure, wherein the ring body 1 is made of rubber material, a through hole 2 in the middle of the ring body 1 is a round hole, the diameter of the through hole 2 is 3mm, an inwards concave step groove 3 is arranged on one side surface of the ring body 1, the step groove 3 is a round groove, the step groove 3 is coaxially arranged with the through hole 2 in the middle of the ring body 1, and a step surface 4 facing the step groove 3 is arranged between the step groove 3 and the through hole 2; the ring body 1 is provided with the step groove 3, the front surface is the front surface, and the front surface of the ring body 1 is in an arc surface structure by bending the ring body 1 from the middle position to two sides towards the front surface of the ring body 1. The side surface of the ring body 1, which is not provided with the step groove 3, is a reverse surface, and the reverse surface of the ring body 1 is also of 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 into the step groove 3, the front surface of the ring body 1 can be tightly attached to the outer surface of the drain pipe 5, the back surface of the ring body 1 can be more tightly attached to the pipe clamp 6, and the sealing performance between the drain pipe 5 and the pipe clamp 6 can be remarkably improved.
