Description

Technical Field

[0001] The utility model belongs to the field of sealing parts and relates to a rubber gasket, in particular to an anti-deformation and vibration-damping rubber gasket. Background Art

[0002] Rubber is a highly elastic polymer material with reversible deformation. After processing, it has properties such as elasticity and impermeability. Rubber products made of rubber as raw material are widely used in all aspects of life or industry.

[0003] In the industrial field, rubber pads made of rubber are used for vibration reduction during the use of industrial equipment to provide shock-absorbing protection for industrial equipment. The rubber gaskets themselves do not have any supporting force, which causes the rubber gaskets to deform to a large extent when under pressure, and even crack, which gradually reduces the shock-absorbing effect and reduces the service life of the rubber gaskets, thus affecting the shock-absorbing effect of the rubber gaskets. Summary of the invention

[0004] The utility model aims to provide an anti-deformation vibration-damping rubber gasket to solve the above problems existing in the prior art.

[0005] The purpose of the utility model can be achieved through the following technical solutions: an anti-deformation shock-absorbing rubber gasket, comprising two rubber gasket bodies arranged in corresponding structures and used for object vibration reduction, characterized in that a support ring frame for improving the anti-deformation ability of the rubber gasket body is arranged between the two rubber gasket bodies, and an inner sealing ring that cooperates with the rubber gasket body is inlaid on the inner peripheral wall of the support ring frame;

[0006] The support ring frame is provided with a plurality of through holes for installing the rubber gasket body;

[0007] The inner peripheral wall of the support ring frame is provided with a plurality of embedding grooves for facilitating the embedding and matching of the inner sealing ring;

[0008] The outer peripheral wall of the inner sealing ring extends radially outward to form a plurality of inlay portions that cooperate with the inlay grooves;

[0009] The inlay portion and the inlay groove are both arranged in a V-shaped structure in cross section;

[0010] A plurality of connecting parts that cooperate with the through holes are arranged on the corresponding end surfaces of the two rubber gasket bodies, and the connecting parts penetrate into the through holes.

[0011] In the above-mentioned anti-deformation shock-absorbing rubber gasket, a plurality of pressure relief holes are respectively provided on the side walls of the plurality of through holes for alleviating the rupture of the rubber gasket body due to overload pressure.

[0012] In the above-mentioned anti-deformation shock-absorbing rubber gasket, the two rubber gasket bodies are respectively located at the two ends of the support ring frame and are arranged in corresponding structures. The rubber gasket bodies cooperate with each other through the connecting parts and the through holes to achieve radial limiting support.

[0013] In the above-mentioned anti-deformation shock-absorbing rubber gasket, the inner diameters of the inner sealing ring and the rubber gasket body are equal, and they are connected to the inner peripheral wall of the supporting ring frame through the mutual cooperation of the embedding part and the embedding groove.

[0014] In the above-mentioned anti-deformation shock-absorbing rubber gasket, the rubber gasket and the inner sealing ring can be made of nitrile rubber material, and the support ring frame is woven from carbon spring steel wire.

[0015] Compared with the prior art, the present invention has a simple structural design for the anti-deformation shock-absorbing rubber gasket. The support ring frame, the inner sealing ring and the rubber gasket main body structure are used to form an elastic support for the rubber gasket main body, so that while the rubber gasket main body supports the strength, the direction of its compression deformation is limited, thereby improving the service life of the rubber gasket main body. In addition, a plurality of groups of pressure relief holes are provided on the side wall of the through hole of the support ring frame. When subjected to external pressure, the pressure relief holes evenly distributed inside the rubber gasket main body can evenly disperse the pressure inside the rubber gasket main body, so that the overall pressure of the rubber gasket main body is relatively uniform, thereby preventing one end of the rubber gasket main body from being excessively deformed and cracked due to compression.

[0021] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0022] like Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, the anti-deformation shock-absorbing rubber gasket comprises two rubber gasket bodies 1 which are arranged in corresponding structures and are used for reducing vibration of objects. A support ring frame 2 for improving the anti-deformation ability of the rubber gasket body 1 is arranged between the two rubber gasket bodies 1. An inner sealing ring 3 which cooperates with the rubber gasket body 1 is inlaid on the inner peripheral wall of the support ring frame 2. A plurality of through holes 4 for installing the rubber gasket body 1 are penetrated through the support ring frame 2. A plurality of inlay grooves 5 which are convenient for inlaying and matching the inner sealing ring 3 are opened on the inner peripheral wall of the support ring frame. A plurality of inlay portions 6 which cooperate with the inlay groove 5 are radially extended outward from the outer peripheral wall of the inner sealing ring 3. The cross-sections of the inlay portions 6 and the inlay groove 5 are arranged in a V-shaped structure. On the corresponding end surfaces of the two rubber gasket bodies 1, A plurality of connection parts 7 cooperating with the through hole 4 are provided, and the connection parts 7 are inserted into the through hole 4. The structure is simple in design, and the support ring frame 2, the inner sealing ring 3 and the rubber gasket main body 1 are used to form an elastic support for the rubber gasket main body 1, so that while the rubber gasket main body 1 supports the strength, the direction of its compression deformation is limited, thereby improving the service life of the rubber gasket main body 1, and a plurality of groups of pressure relief holes 8 are provided on the side wall of the through hole 4 of the support ring frame 2. When subjected to external pressure, the pressure relief holes 8 evenly distributed inside the rubber gasket main body 1 can evenly disperse the pressure inside the rubber gasket main body 1, so that the rubber gasket main body 1 is relatively evenly compressed as a whole, thereby preventing one end of the rubber gasket main body 1 from being excessively compressed and deformed and ruptured.

[0023] To elaborate further, in order to prevent the rubber gasket from being deformed under pressure, a number of pressure relief holes 8 are respectively opened on the side walls of the through holes 4 to relieve the rubber gasket body 1 from being ruptured due to overload. When subjected to external pressure, the evenly distributed pressure relief holes 8 inside the rubber gasket body 1 can evenly disperse the pressure inside the rubber gasket body 1, so that the rubber gasket body 1 is more evenly pressurized as a whole, thereby preventing one end of the rubber gasket body 1 from being excessively deformed under pressure and ruptured.

[0024] To elaborate further, in order to facilitate the installation and connection of the rubber gasket body 1, the two rubber gasket bodies 1 are respectively located at both ends of the support ring frame 2 and are arranged in a corresponding structure. The rubber gasket body 1 cooperates with the through hole 4 through the connecting part 7 to achieve radial limiting support.

[0025] Preferably, the inner diameters of the inner sealing ring 3 and the rubber gasket body 1 are equal, and the inner sealing ring 3 is connected to the inner peripheral wall of the supporting ring frame 2 by the matching of the embedding portion 6 and the embedding groove 5 .

[0026] Preferably, the rubber gasket and the inner sealing ring 3 can be made of nitrile rubber material, and the support ring frame 2 is woven from carbon spring steel wire, which has strong elasticity and strong stress resistance.

[0027] The specific embodiments described herein are merely examples of the spirit of the present invention. Those skilled in the art may make various modifications or additions to the specific embodiments described or replace them in similar ways, but they will not deviate from the spirit of the present invention or exceed the scope defined by the appended claims.

[0028] Although the terms such as rubber gasket body 1, support ring frame 2, inner sealing ring 3, through hole 4, embedding groove 5, embedding part 6, connecting part 7, pressure relief hole 8 are used more frequently in this article, the possibility of using other terms is not excluded. The use of these terms is only for the purpose of more conveniently describing and explaining the essence of the utility model; interpreting them as any additional restrictions is contrary to the spirit of the utility model.
