Abstract
The utility model discloses a car oil seal which comprises a body (1) which is provided with a center hole. The body (1) comprises a first section (1.1) and a second section (1.2), wherein the external diameter of the second section (1.2) is greater than that of the first section (1.1), and the combining position of the first section (1.1) and the second section (1.2) is provided with a radial convex ring (1.3). The car oil seal is capable of enabling assembling to be easy and guaranteeing a sealing function.
Description
Technical field
The utility model relates to a kind of automobile oil 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 automobile oil seal is arranged at present, comprise the body that is provided with center hole, this body comprises that first paragraph and second segment form, the external diameter of second segment is greater than the external diameter of first paragraph, in use, be embedded in the step hole of the pump housing, first paragraph and the second segment of this body match in step hole.More than the Sealing of this structure have the following disadvantages: because the external diameter of first paragraph and second segment differs less, generally only have about 1mm, in the time of in being assembled to the step hole of the pump housing, axial limiting is relatively poor, may make Sealing extend into the less place of internal diameter of step hole fully, thereby lose seal action.
The model utility content
The technical problems to be solved in the utility model is that a kind of automobile oil seal that assembling is simple, guarantee seal action that makes is provided.
The technical solution of the utility model is, a kind of automobile oil seal with following structure is provided, comprises the body that is provided with center hole, described body comprises first paragraph and second segment, the external diameter of described second segment is greater than the external diameter of first paragraph, and the binding site of described first paragraph and second segment is provided with radial convex loop.
Described radial convex loop is greater than the external diameter of described second segment.
The height of described radial convex loop is 3mm.
After adopting above structure, the utility model compared with prior art, have the following advantages: because the binding site of described first paragraph and second segment is provided with radial convex loop, this radial convex loop can be embedded in the annular radial groove of pump housing step hole, thereby carry out axial limiting, the less place of internal diameter that makes Sealing extend into step hole fully can be prevented like this, thereby seal action can be guaranteed.
Description of drawings
Accompanying drawing is the structural representation of a kind of automobile oil seal of the present utility model.
As shown in the figure: 1, body, 1.1, first paragraph, 1.2, second segment, 1.3, radial convex loop.
Embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
As shown in the figure, a kind of automobile oil seal of the present utility model, comprise the body 1 that is provided with center hole, described body 1 comprises first paragraph 1.1 and second segment 1.2, the external diameter of described second segment 1.2 is greater than the external diameter of first paragraph 1.1, and the binding site of described first paragraph 1.1 and second segment 1.2 is provided with radial convex loop 1.3.
Described radial convex loop 1.3 is greater than the external diameter of described second segment 1.2.
The height of described radial convex loop 1.3 is 3mm.
Claims (3)
1. automobile oil seal, comprise the body (1) that is provided with center hole, described body (1) comprises first paragraph (1.1) and second segment (1.2), the external diameter of described second segment (1.2) is characterized in that greater than the external diameter of first paragraph (1.1): the binding site of described first paragraph (1.1) and second segment (1.2) is provided with radial convex loop (1.3).
2. a kind of automobile oil seal according to claim 1, it is characterized in that: described radial convex loop (1.3) is greater than the external diameter of described second segment (1.2).
3. a kind of automobile oil seal according to claim 1, it is characterized in that: the height of described radial convex loop (1.3) is 3mm.
