The present invention aims at solving at least one of the technical problems in the related art to a certain extent. Therefore, an object of the utility model is to provide a corrosion-resistant rubber seal who prevents deformation sets up the elasticity reinforcement in the sealing washer to be equipped with built-in elastic ring, effectively increase the deformation recovery ability of sealing washer, increase life.
The technical scheme of the utility model as follows:
the utility model provides a corrosion-resistant anti-deformation rubber seal, includes the sealing washer body, and the shaping of sealing washer body middle part has towards the annular internal expanding groove that expands and outwards link up in the outside ring-type to including expand the inslot and set up the elasticity reinforcement that expands the groove lateral wall in a plurality of laminating.
Further, the elastic reinforcing member is a hollow member.
Furthermore, the elastic reinforcing piece is a U-shaped metal elastic piece.
Further, the outer ring of the seal ring body is protruded outwards to form a thickened reinforcing part.
Further, the inner ring of the sealing ring body is designed to be a straight edge.
Furthermore, an internal elastic ring is arranged in the elastic reinforcing piece so as to be attached to the inner wall of the elastic reinforcing piece.
Furthermore, limiting parts are formed on two sides of the elastic reinforcing part and used for supporting and limiting the built-in elastic ring.
Furthermore, a positioning bulge is formed on the contact surface of the built-in elastic ring and the elastic reinforcing piece, and a positioning hole is correspondingly formed in the elastic reinforcing piece.
The utility model provides a beneficial effect: the inner expanding groove is arranged, so that the limit of the elastic reinforcing part can be formed, the assembly of a limit part formed at the top of the sealing ring body can be avoided, the structure of the sealing ring can be simplified, the production cost can be reduced to a certain extent, and the recovery capability of the sealing ring when the sealing ring receives pressure can be improved by matching with the elastic reinforcing part; meanwhile, the wall thickness of the material at the bottom of the outer ring and the inner expanding groove is relatively reduced due to the arrangement of the inner expanding groove, so that the top of the outer ring is easier to expand and extrude to deform, and the sealing property of the outer ring is ensured.

Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments.
Examples of which are illustrated in the accompanying drawings, wherein like reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the drawings are exemplary and intended to be used for explaining the present invention, and should not be construed as limiting the present invention.
Referring to fig. 1-3, a corrosion-resistant anti-deformation rubber seal ring comprises a seal ring body, wherein an inner expanding groove 3 which is expanded towards an outer ring 1 and is communicated outwards is formed in the middle of the seal ring body, namely, the inner expanding groove 3 is in a ladder shape with the bottom edge longer than the top edge, and a plurality of elastic reinforcing members 4 which are attached to the side wall of the inner expanding groove 3 are arranged in the inner expanding groove 3. The elastic reinforcing part 4 is a hollow part, in the embodiment, a U-shaped metal elastic sheet is selected, and the opening of the U-shaped metal elastic sheet faces downwards; of course, the opening can be arranged upward.
The inner expanding groove 3 is arranged, so that the elastic reinforcing part 4 can be limited, the assembly of a forming limiting part at the top of the sealing ring body can be avoided, the sealing ring structure can be simplified, the production cost can be reduced to a certain degree, and the recovery capability of the sealing ring when the sealing ring receives pressure can be improved by matching with the elastic reinforcing part 4; meanwhile, the wall thickness of the material at the bottoms of the outer ring 1 and the inner expanding groove 3 is relatively reduced due to the arrangement of the inner expanding groove 3, so that the top of the outer ring 1 is easier to expand and extrude to deform, and the sealing property of the outer ring is ensured.
In addition, the outer ring 1 of the sealing ring body protrudes outwards to form a thickened reinforcing part 11, so that the wall thickness of rubber is increased, deformation is easier to occur when the rubber is pressed, and the sealing performance is improved to a certain extent; the inner ring 2 is a straight-sided design.
In order to further increase the elastic recovery capability, an internal elastic ring 5 is arranged in the elastic reinforcing piece 4 so as to be attached to the inner wall of the elastic reinforcing piece 4;
