Abstract

The utility model relates to a conical sealing ring. The conical sealing ring comprises a sealing ring body, wherein a cylindrical through hole which penetrates through two end surfaces of the sealing ring body is formed in the middle of the sealing ring body; the outer contour of the sealing ring body is a conical transitional surface; a conical angle of the transitional surface is 45-75 degrees; at least three ribs are arranged on the transitional surface at intervals; a surrounding raised ring is arranged at the outer edge of the large-diameter end of the conical transitional surface of the sealing ring body. The conical sealing ring is simple in structure; a sealing surface is a conical inclined surface, and the ribs are arranged on the sealing surface, so that the number of contact surfaces of the sealing ring is increased; the conical sealing ring has a good sealing effect in the usage process and is convenient and quick, and the cost is saved.

Description

A kind of conical seal ring

Technical field:

The utility model relates to a kind of seal ring, relates in particular to a kind of conical seal ring.

Background technique:

In the drinking water pipeline adapter connector, need to use seal ring, this class seal ring is generally the O RunddichtringO at present, and its cross section is circular, and sealing effect is not very desirable.

The model utility content:

Main purpose of the present utility model is in order to overcome the above-mentioned deficiency of prior art, provides a kind of simple in structure, the conical seal ring of good sealing effect.

For solving the problems of the technologies described above, the utility model adopts following technological scheme to be:

A kind of conical seal ring, comprise the seal ring body, wherein, the middle part of described seal ring body is provided with the cylindrical hole that runs through seal ring body both ends of the surface, the external frame of seal ring body is conical transitional surface, the cone angle of transitional surface is 45 °-75 °, on transitional surface, is arranged at intervals with at least three convex tendons, the outer rim that the seal ring body is positioned at conical transition face larger diameter end be provided with around protruding ring.

Further, the cone angle of described transitional surface is 65 °.

The beneficial effects of the utility model are: the utility model is simple in structure, because sealing surface is conical inclined surface, and on sealing surface, is provided with convex tendon, increased the surface of contact number of seal ring, in use have good sealing effect, convenient and swift, and also cost-saving.

The accompanying drawing explanation:

Fig. 1 is structural representation of the present utility model.

Embodiment:

Below in conjunction with accompanying drawing, embodiment of the present utility model is described in further detail:

As shown in Figure 1, a kind of conical seal ring of the present utility model, comprise seal ring body 1, the middle part of seal ring body 1 is provided with the cylindrical hole 2 that runs through seal ring body 1 both ends of the surface, the external frame of seal ring body 1 is conical transitional surface 3, and the cone angle of transitional surface 3 is 45 °-75 °, on transitional surface 3, is arranged at intervals with three convex tendons 4, the outer rim that seal ring body 1 is positioned at conical transition face 3 larger diameter end be provided with around protruding ring 5, make seal ring form the truncated cone structure.
