Abstract
The utility model relates to a seal ring, which is an annular seal ring, wherein the structure of the seal ring is divided into an inner diameter and an outer diameter; the maximum outer diameter circumference part of the outer diameter of the seal ring is combined by a plane and a cambered surface, i.e., the cambered surface is positioned at a middle position of the plane; the inner diameter circumference part of the seal ring is in line seal, i.e., the inner diameter is provided with a semicircular convex surface. The seal ring has the beneficial effects that part burrs, which affect the sealing, on the part do not exist after a mold parting surface is canceled on the maximum outer diameter part of the outer diameter of the seal ring, and poor sealing caused by the defect of the sealing plane is eliminated due to the advantage that face seal of the inner diameter circumference is changed into line seal.
Description
Technical field
The utility model relates to the seal ring field, mainly is the seal ring in the brake master cylinder in a kind of brake system of car.
Background technique
At present, the seal ring in the master cylinder that our company brakes, as shown in Figure 1, because there is certain defective in design, for example seal ring external diameter maximum outside diameter place has mold joint, and this position can produce the part burr, thus the influence sealing; The internal diameter circumference is face sealing, the poor sealing that causes owing to the sealing plane defectiveness.
Summary of the invention
The purpose of this utility model is to overcome the deficiency that prior art exists, and a kind of seal ring of good seal performance is provided.
The purpose of this utility model is finished by following technical solution, the sealing circle is an O-ring seal, its structure is divided into internal diameter and external diameter, and the maximum outside diameter circumference place of described seal ring external diameter is combined by plane and arc shaped surface, and namely arc shaped surface is positioned at the neutral position, plane; Internal diameter of the seal ring circumference place is linear sealing, and namely internal diameter is provided with semi-circular convex surface.
The beneficial effects of the utility model are: behind the seal ring external diameter maximum outside diameter place cancellation mould mold joint, the part burr of this position influence sealing does not just exist; It is to eliminate the poor sealing that causes owing to the sealing plane defectiveness that the internal diameter circumference changes the advantage that face is sealed into linear sealing.
Description of drawings
Fig. 1 is the structural representation of existing O-ring seal.
Fig. 2 is structural representation of the present utility model.
Label in the accompanying drawing is respectively: 1, O-ring seal; 11, internal diameter; 12, external diameter; 13, plane; 14, arc shaped surface; 15, convex surface.
Embodiment
Below in conjunction with accompanying drawing the utility model is done detailed introduction: as shown in Figure 2, the sealing circle is an O-ring seal 1, and its structure is divided into internal diameter 11 and external diameter 12; The maximum outside diameter circumference place of described seal ring external diameter 12 is combined by plane 13 and arc shaped surface 14, and namely arc shaped surface 14 is positioned at 13 neutral positions, plane; Internal diameter of the seal ring 11 circumference places are linear sealing, and namely internal diameter 11 is provided with semi-circular convex surface 15.
The external diameter 12 maximum outside diameter places cancellation mould mold joint of this O-ring seal 1, internal diameter 11 circumference places change face and are sealed into linear sealing, are used for the sealing of brake master cylinder reservoir and master cylinder body.
The utility model is not limited to above-mentioned mode of execution; no matter do any variation in its shape or material formation; every employing structural design provided by the utility model all is a kind of distortion of the present utility model, all should think within the utility model protection domain.
