The cross section of the special-shaped sealing ring main body is spindle-shaped.
The special-shaped sealing ring main body is provided with a columnar reinforcing rib, and the thickness of the cross section of the columnar reinforcing rib is matched with the width of the sealing groove of the corresponding sealing end cover.
The height of the special-shaped sealing ring main body is larger than the depth of the sealing groove of the corresponding sealing end cover.
Compared with the prior art, the utility model has the beneficial technical effects that:
the section of the special-shaped sealing ring main body is designed to be thick in the middle and thin on two sides, so that compared with a common rectangular or circular section sealing ring with the same shape, the special-shaped sealing ring has the advantages of material saving, better bending property and following property, and good adaptability to shape mutation and irregular sealing grooves. Meanwhile, the sealing rings which are thick in the middle of the cross section and thin on two sides can be easily installed in or taken out of various complex shapes, so that the pressure generated in the use process is reduced, the permanent deformation and the aging are not easy to generate, the service life of the device is prolonged, and the technical problem that the service life is short due to the fact that the formability and the adaptability of the rubber sealing ring are poor in the prior art is solved.
And (II) the area of the end surface of the sealing ring body is smaller, when the sealing end cover is arranged on the shell joint surface through the connecting hole on the sealing end cover, the end surface of the sealing ring higher than the joint surface of the sealing end cover is extruded by the joint surface to generate deformation, the contact area between the end surface of the sealing ring after the extrusion deformation and the joint surface is small, the probability of contact with a high point on the joint surface is small, the fitting performance is good, and the sealing performance is better.

Detailed Description
It should be noted that the sealing ring in fig. 1 in the present invention includes three dimensions, namely, a length, a height and a thickness, wherein the length refers to the total circumference of one circle of the sealing ring, the height refers to the height of the sealing ring when the sealing ring is horizontally placed, and the thickness refers to the thickness of the cross section of the sealing ring.
All parts in the present invention are those known in the art, unless otherwise specified.
The following embodiments of the present invention are provided, and it should be noted that the present invention is not limited to the following embodiments, and all equivalent changes based on the technical solutions of the present invention are within the protection scope of the present invention.
The utility model provides a novel end face rubber sealing ring, which comprises a special-shaped sealing ring main body 1, wherein a plurality of columnar reinforcing ribs 2 are arranged on the inner wall and the outer wall of the special-shaped sealing ring main body 1 as shown in figures 1 to 7;
the thickness of the cross section of the special-shaped sealing ring body 1 is reduced from the middle to two sides.
In the technical scheme, the section of the special-shaped sealing ring main body is designed to be a section with thick middle and thin two sides, and compared with a common rectangular or circular section sealing ring with the same shape, the special-shaped sealing ring has the advantages of saving materials, being better in bending property and following property, and having good adaptability to shape mutation and irregular sealing grooves. Meanwhile, the sealing ring with the thick middle part and the thin two sides of the cross section can be easily installed or taken out of various complex shapes, so that the pressure generated in the use process is reduced, the permanent deformation and the aging are not easy to generate, the service life of the device is prolonged, and the technical problem that the service life is short due to the fact that the formability and the adaptability of the rubber sealing ring are poor in the prior art is solved.
Specifically, the columnar reinforcing ribs 2 are arranged at corresponding positions on the inner wall and the outer wall of the special-shaped sealing ring main body 1, and the pressure-resistant variable strength of the sealing ring is increased.
Specifically, the height of the columnar reinforcing rib 2 is smaller than that of the special-shaped sealing ring main body 1, so that the contact point of the sealing ring and the sealing end cover only exists on the end face of the sealing ring body, the contact area is reduced, and the columnar reinforcing rib is prevented from deforming due to extrusion.
Specifically, the cross section of the special-shaped sealing ring main body 1 is spindle-shaped, the spindle-shaped cross section design saves more materials, the bending property and the following property of the sealing ring are better, and the special-shaped sealing ring has good adaptability to shape mutation and irregular sealing grooves.
Specifically, the cross section thickness that is provided with column strengthening rib 2 department on the dysmorphism sealing washer main part 1 matches with the width phase-match of the seal groove 4 that corresponds end cover 3, has guaranteed that the sealing washer body that is provided with the column strengthening rib can inseparably imbed in the seal groove, and can not deviate from in the seal groove.
Specifically, the height of the special-shaped sealing ring main body 1 is greater than the depth of the sealing groove 4 of the corresponding sealing end cover 3, so that when the sealing end cover 3 is installed on the shell joint surface through the connecting hole on the sealing end cover, the end face of the sealing ring, which is higher than the joint surface of the sealing end cover, is extruded by the joint surface to deform and is tightly attached to the shell joint surface, and the end face is better sealed.
