Abstract

The utility model relates to a reinforced rubber gasket, which belongs to the technical field of rubber gaskets and comprises two rubber rings which are arranged in parallel, wherein the end surfaces of the rubber rings which are close to each other are respectively and fixedly connected with metal rings, the metal rings are made of stainless steel plates, a sealing air bag ring and an elastic component are connected between the two metal rings, the rubber rings, the metal rings and the sealing air bag ring are coaxially arranged, and the elastic component is provided with five groups at equal intervals along the circumferential direction of the metal rings; the elastic component is arranged between the metal rings, so that the buffer effect can be achieved when the bolt is fastened, and when the rubber rings are extruded, the two rubber rings are close to each other, so that the damage caused by hard extrusion generated by using a single rubber gasket is avoided; in addition, when the sealing air bag ring is extruded, the inner ring part of the sealing air bag ring protrudes inwards so as to tightly wrap parts and avoid the corrosion of flowing media.

Description

Reinforced rubber gasket

Technical Field

The utility model belongs to the technical field of the rubber gasket technique and specifically relates to a reinforcement type rubber gasket is related to.

Background

The rubber gasket has the performances of oil resistance, acid and alkali resistance, cold and heat resistance, aging resistance and the like, can be directly cut into sealing gaskets in various shapes, and is widely applied to the industries of medicine, electronics, chemical industry, static resistance, flame retardance, food and the like. The existing rubber gasket is easy to deform and damage due to the fact that bolt fixing force is high in the using process, and after two ends of the gasket meet flowing media, the flowing media enter a central hole through a gap, corrosion or corrosion is caused to other parts, and the service lives of the other parts are shortened. To solve the problems in the prior art, a reinforced rubber gasket is provided.

SUMMERY OF THE UTILITY MODEL

The utility model discloses to the problem among the above-mentioned prior art, provide a reinforcement type rubber gasket, can realize through following technical scheme:

the utility model provides a reinforcement type rubber gasket, includes the rubber circle of two parallel arrangement, fixedly connected with metal loop, two on the terminal surface that the rubber circle is close to each other respectively be connected with sealed gasbag ring sum elastic component between the metal loop, rubber circle, metal loop and the coaxial setting of sealed gasbag ring, elastic component is provided with a plurality of groups along the circumferencial direction equidistance of metal loop.

The utility model discloses further set up to: the elastic assembly comprises a first connecting seat, a second connecting seat and a spring, the first connecting seat is fixedly connected to one metal ring, the second connecting seat is fixedly connected to the other metal ring, the second connecting seat is connected with the first connecting seat in a sliding mode, two ends of the spring are fixedly connected with the two metal rings respectively, and the spring is arranged in inner cavities of the first connecting seat and the second connecting seat.

The utility model discloses further set up to: fixedly connected with snap ring on the inside wall of first connecting seat, fixedly connected with bulge loop on the outside wall of second connecting seat, the bulge loop slides and connects in the inner chamber of first connecting seat, the external diameter of bulge loop is greater than the internal diameter of snap ring.

The utility model discloses further set up to: the metal ring is made of a stainless steel plate.

The utility model discloses further set up to: the elastic component is provided with five groups.

To sum up, the utility model discloses a beneficial technological effect does:

the elastic component is arranged between the metal rings, so that the buffer effect can be achieved when the bolt is fastened, and when the rubber rings are extruded, the two rubber rings are close to each other, so that the damage caused by hard extrusion generated by using a single rubber gasket is avoided; in addition, when the sealing air bag ring is extruded, the inner ring part of the sealing air bag ring protrudes inwards so as to tightly wrap parts and avoid the corrosion of flowing media.

Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings.

Examples

As shown in fig. 1-5, for the utility model discloses a reinforcement type rubber gasket, including two parallel arrangement's rubber circle 1, fixedly connected with metal ring 2 respectively on the terminal surface that rubber circle 1 is close to each other, metal ring 2 adopts corrosion resistant plate to make, is connected with sealed gasbag ring 3 and elastic component 4 between two metal ring 2, and rubber circle 1, metal ring 2 and the coaxial setting of sealed gasbag ring 3, elastic component 4 are provided with five futiles groups along the equidistance of the circumferencial direction of metal ring 2. The elastic component 4 arranged between the metal rings 2 can play a role of buffering when the bolt is fastened, and when the rubber rings 1 are extruded, the two rubber rings 1 are close to each other, so that the damage caused by rigid extrusion generated by using a single rubber gasket is avoided; in addition, when the sealing air bag ring 3 is extruded, the inner ring part of the sealing air bag ring 3 protrudes inwards to tightly wrap parts, so that the corrosion of a flowing medium is avoided.

Elastic component 4 includes first connecting seat 41, second connecting seat 42 and

spring

43, 41 fixed connection of first connecting seat is on one of them
