Abstract
Description
TECHNICAL FIELD
[0001] The utility model relates to rubber gasket technical field especially a kind of wear-resistant high elasticity sealing rubber gasket. BACKGROUND
[0002] Rubber gasket has oil resistance, acid and alkali resistance, cold and heat resistance, aging resistance and other properties, can be directly cut into various shapes of sealing gasket, widely used in medicine, electronics, chemical industry, antistatic, flame retardant, food and other industries.
[0003] The existing rubber gasket is poor in wear resistance when in use, which affects its sealing effect, and the existing rubber gasket is poor in elasticity, and the above problems are solved by providing a wear-resistant high elasticity sealing rubber gasket. SUMMARY
[0004] In order to overcome the above-mentioned defects existing in the prior art, the utility model provides a wear-resistant high elasticity sealing rubber gasket.
[0005] The utility model discloses a wear-resistant high elasticity sealing rubber gasket, including outside rubber, the inside middle part of outside rubber is placed with circular rubber rope, the outside fixed mounting inner ring of circular rubber rope, the outside of inner ring is connected with support body, the outside fixed mounting outer ring of support body, the inside of outside rubber and outer ring is filled with filled rubber.
[0006] Further, the material of the outer rubber is polyurethane rubber.
[0007] Further, the material of the filled rubber is silicone rubber.
[0008] Further, the material of the circular rubber rope is hydrogenated butyronitrile.
[0009] Further, the material of the support body, the outer ring and the inner ring is butyl rubber.
[0010] The utility model has the advantages that the outer rubber made of polyurethane rubber makes the outer side of the rubber gasket more wear-resistant, the circular rubber rope arranged in the middle for support, the support body, the outer ring and the inner ring enhance the strength of the rubber gasket, and the filled rubber made of silicone rubber filled in the inner side of the outer rubber makes the rubber gasket more elastic. BRIEF DESCRIPTION OF DRAWINGS
[0011] The utility model will be further described below in combination with drawings and examples.
[0012] Fig. 1 It is the front view of the utility model;
[0013] Fig. 2 This is a top view of the front of this utility model;
[0014] Fig. 3 This is a side sectional view of the present invention.
[0015] In the diagram: 1. Outer rubber, 2. Filler rubber, 3. Circular rubber rope, 4. Support body, 5. Outer ring body, 6. Inner ring body. Detailed Implementation
[0016] To more clearly illustrate the technical solution of this utility model, the following description is made in conjunction with the accompanying drawings. Obviously, the drawings described below are only one embodiment of this utility model. For those skilled in the art, other embodiments can be obtained based on these drawings and embodiments without creative effort, and all of them fall within the protection scope of this utility model.
[0017] like Figs. 1 to 3 As shown, this utility model includes an outer rubber 1, which is made of polyurethane rubber. Polyurethane rubber has advantages such as high wear resistance, making the outer side of the rubber gasket more wear-resistant.
[0018] like Fig. 2 and Fig. 3 As shown, a circular rubber rope 3 is placed in the middle of the inner side of the outer rubber 1. The circular rubber rope 3 is made of hydrogenated nitrile butadiene rubber, which has the advantages of high strength and is used to enhance the overall strength of the rubber gasket.
[0019] like Fig. 2 and Fig. 3 As shown, an inner ring 6 is fixedly installed on the outer side of the circular rubber rope 3. A support body 4 is connected to the outer side of the inner ring 6. An outer ring 5 is fixedly installed on the outer side of the support body 4. The support body 4, the outer ring 5 and the inner ring 6 are made of butyl rubber, so that the whole composed of the support body 4, the outer ring 5 and the inner ring 6 can play a supporting role and further enhance the strength of the rubber gasket.
[0020] like Fig. 2 and Fig. 3 As shown, both the outer rubber 1 and the outer ring 5 are filled with filling rubber 2. The filling rubber 2 is made of silicone rubber, which has the advantages of high elasticity, and is used to make the rubber gasket more elastic.
[0021] In use, the outer rubber 1 made of polyurethane rubber makes the outer side of the rubber gasket more wear-resistant. The circular rubber rope 3, support body 4, outer ring body 5 and inner ring body 6 in the middle enhance the strength of the rubber gasket. The silicone rubber filling rubber 2 inside the outer rubber 1 makes the rubber gasket more elastic.
[0022] The above embodiments are only exemplary embodiments of the present application and are not intended to limit the present application. The protection scope of the present application is defined by the claims. Those skilled in the art can make various modifications or equivalent replacements to the present application within the spirit and protection scope of the present application, and such modifications or equivalent replacements should also be considered to fall within the protection scope of the present application.
