Description

Technical Field

[0001] The utility model relates to the technical field of sealing rings, in particular to a high-strength pneumatic rubber sealing ring. Background Art

[0002] Pneumatic sealing ring is a commonly used sealing element, which is widely used in the sealing of various rotating equipment in the machinery industry.

[0003] The function of a pneumatic sealing ring is to prevent liquid or gas leakage, and at the same time prevent dust and impurities from entering the interior of the equipment, thus protecting the normal operation of the equipment. A pneumatic sealing ring is usually composed of two main parts: a sealing ring and a spring. The sealing ring is the main body of the sealing ring, and is usually made of rubber, polyurethane, polytetrafluoroethylene and other materials, and has good sealing and wear resistance. The spring is used to maintain the pressure of the sealing ring so that it fits tightly with the sealing surface, thereby achieving a good sealing effect. Existing pneumatic sealing rings are easily worn and frequently replaced, which can easily cause production accidents. Therefore, it is necessary to provide a high-strength pneumatic rubber sealing ring. Utility Model Content

[0007] The inner buckle ring is a planar annular structure, and the outer side of the inner buckle ring is correspondingly connected to the first circle body.

[0008] The second ring body is a cylindrical structure with two ends open, and the outer diameter of the second ring body is smaller than the outer diameter of the first ring body.

[0009] Two corresponding slots are formed in the ring body, and the two slots are symmetrical about the center of the ring body.

[0010] The two clamping grooves respectively pass through the first circle body, the inner buckle ring and the second circle body.

[0011] A plurality of triangular reinforcing columns are evenly arranged at the connection between the material base layer and the adhesive layer, and the reinforcing columns are inserted into the adhesive layer.

[0012] The beneficial effects of the utility model are:

[0013] 1. The utility model provides a high-strength pneumatic rubber sealing ring with a buckle, which can enhance the bonding strength between the ring body and the sealing surface through the buckle, thereby improving the sealing effect.

[0014] 2. The utility model provides a high-strength pneumatic rubber sealing ring with a plurality of reinforcing columns inserted into the adhesive layer. The reinforcing columns can significantly increase the contact area between the upper adhesive layer and the material base layer, thereby improving the adhesion between the two and enhancing the structural strength of the ring body.
