Abstract
The utility model discloses a waterproof sealing part. The waterproof sealing part comprises a body (1) which is provided with a central hole (1.1), the bottom of the body (1) is provided with a radial protruding ring (1.2), and the top end face of the body (1) is provided with at least one arc groove (1.3). The waterproof sealing part is good in circumferential direction limiting and good in sealing effect.
Description
Technical field
The utility model relates to a kind of waterproof seal.
Background technique
Sealing is to prevent fluid or material or the part of solid particle from leaking and prevent the component of the intrusion machinery equipment inside such as introduced contaminants such as dust and moisture between adjacent junction plane.A kind of waterproof seal is arranged at present, comprise the body that is provided with center hole, be provided with radial convex loop in the bottom of body, be provided with the right angle chamfering at the top of body.In use, be embedded into the through hole of the pump housing, its radial convex loop then is close in the outerplanar of the pump housing, the top of body then with through hole in step surface offset because the top end face of body is the plane, circumferential so spacing property is relatively poor.
The model utility content
The technical problems to be solved in the utility model is, provides that a kind of circumferential spacing property is good, the waterproof seal of good sealing effect.
The technical solution of the utility model is, a kind of waterproof seal with following structure is provided, and comprises the body that is provided with center hole, and the bottom of described body is provided with radial convex loop, and the top end face of described body is provided with at least one arc groove.
The quantity of described arc groove is four, and distributes along the even circumferential of body.
The degree of depth of described arc groove is 0.5mm.
After adopting above structure, the utility model compared with prior art, have the following advantages: because the top end face of described body is provided with at least one arc groove, the through hole that is embedded into like this pump housing, its radial convex loop then is close in the outerplanar of the pump housing, the arc groove on the top of body then with through hole in the projection of step surface embed mutually, circumferential so spacing property is relatively poor, ensures good sealing effect.
