Abstract
Description
Technical Field
[0001] This utility model relates to the field of sealing ring technology, and in particular to an elastic sealing rubber ring. Background Technology
[0002] A sealing ring is a fitting used for sealing. Its main body is shaped like a ring cover, and rubber is a commonly used material for sealing rings.
[0003] Because rubber materials have excellent elasticity, softness, and plasticity, they can closely fit sealing surfaces of various shapes and sizes, thus enabling the sealing ring to form an effective seal. However, over time, the elasticity of the rubber ring deteriorates, causing the surface of the sealing rubber ring to fail to adhere tightly to the contact surface, resulting in a poorer sealing effect. Therefore, we propose an elastic sealing rubber ring that can improve the sealing effect. Utility Model Content
[0004] The purpose of this invention is to provide an elastic sealing rubber ring to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: an elastic sealing rubber ring, comprising:
[0006] The ring body is arranged in a circular shape;
[0007] An elastic mechanism is provided inside the ring body. The elastic mechanism includes elastic rods. A first annular cavity is opened inside the ring body. The elastic rods are spaced apart inside the first annular cavity. A first anti-slip mechanism is provided on the outer wall of the ring body. A second anti-slip mechanism is provided on the inner wall of the ring body. A reinforcement mechanism is provided inside the ring body.
[0008] Preferably, the first anti-slip mechanism includes a first anti-slip pattern, which is formed on the outer wall of the ring body and arranged in a ring array.
[0009] Preferably, the second anti-slip mechanism includes a second anti-slip texture, which is formed on the inner wall of the ring body and arranged in a ring array.
[0010] Preferably, the reinforcing mechanism includes a metal ring, and a second annular groove is formed inside the ring body, with the metal ring inserted inside the second annular groove.
[0011] Preferably, an extension ring is fixedly connected to the top of the ring body, and the inner diameter of the extension ring matches the inner diameter of the ring body.
[0012] Preferably, the thickness of the ring body is 0.3 mm to 0.8 mm, and the thickness of the extension ring is 0.2 mm to 0.5 mm.
[0013] The technical effects and advantages of this utility model are as follows:
[0014] This invention utilizes an elastic mechanism, which consists of two sets located near the outer and inner walls of the ring body, respectively. The elastic rod at the end closest to the ring body is supported by the ring body, causing it to exert a compressive force on the inner wall of the first annular cavity away from the ring body. When the rubber ring is inserted into the sealing hole or placed on the shaft, the outer wall of the ring body compresses the sealing hole, and the inner wall of the ring body compresses the outer wall of the shaft, thus improving the sealing effect of the rubber ring.

[0017] In the figure: 101, ring body; 201, first annular cavity; 202, elastic rod; 301, first anti-slip texture; 401, second anti-slip texture; 501, second annular groove; 502, metal ring; 601, extension ring. Detailed Implementation
[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0019] This utility model provides, for example Figures 1-2 The elastic sealing rubber ring shown includes a ring body 101 and an elastic mechanism, wherein the ring body 101 is arranged in a ring shape;
[0020] In a preferred embodiment, an elastic mechanism is disposed inside the ring body 101. The elastic mechanism includes an elastic rod 202. A first annular cavity 201 is formed inside the ring body 101. The elastic rods 202 are spaced apart inside the first annular cavity 201. A first anti-slip mechanism is provided on the outer wall of the ring body 101, and a second anti-slip mechanism is provided on the inner wall of the ring body 101. A reinforcing mechanism is provided inside the ring body 101. The elastic mechanism is provided in two sets, located near the outer wall and the inner wall of the ring body 101, respectively. The elastic rod 202 near the main body of the ring body 101 is supported by the ring body 101, so that the elastic rod 202 will exert a compressive force on the inner wall of the first annular cavity 201 away from the main body of the ring body 101. Therefore, when the rubber ring is inserted into the sealing hole or the rubber ring is put on the shaft, the outer wall of the ring body 101 will compress the sealing hole, and the inner wall of the ring body 101 will compress the outer wall of the shaft, thereby improving the sealing effect of the rubber ring.
[0021] The first anti-slip mechanism includes a first anti-slip texture 301, which is formed on the outer wall of the ring body 101 and arranged in a ring array. The second anti-slip mechanism includes a second anti-slip texture 401, which is formed on the inner wall of the ring body 101 and arranged in a ring array. The first and second anti-slip textures 301 and 401 increase the amount of material between the sealing ring and the contact surface, whether the sealing ring is inserted into the hole to be sealed or fitted onto the shaft. This makes the sealing ring less prone to slipping or falling off under pressure, thereby enhancing the sealing effect of the sealing ring. Strong friction helps ensure the sealing ring maintains stable sealing performance under harsh conditions such as high pressure or high temperature. Simultaneously, the first anti-slip texture 301 and the second anti-slip texture 401 ensure a tighter and more uniform contact between the sealing ring and the contact surface, reducing the risk of leakage. Especially when the sealing ring is used in dynamic sealing, the first anti-slip texture 301 and the second anti-slip texture 401 provide better tracking and applicability, ensuring the sealing ring closely conforms to the contours of the moving parts. Furthermore, the design of the first anti-slip texture 301 and the second anti-slip texture 401 makes the sealing ring easier to position during installation, reducing errors and difficulties in the installation process. This helps improve installation efficiency and reduces the risk of seal failure due to improper installation. When the sealing ring needs to be removed, the first anti-slip texture 301 and the second anti-slip texture 401 provide additional gripping force, making the removal process smoother. This helps reduce damage to the sealing ring and contact surfaces during disassembly, extending the service life of the sealing ring. The design of the first anti-slip texture 301 and the second anti-slip texture 401 increases the wear resistance of the sealing ring, enabling it to maintain good sealing performance even under prolonged use and high pressure. This helps extend the service life of the sealing ring and reduce the risk of leakage due to wear. The first anti-slip texture 301 and the second anti-slip texture 401 can adapt to the pressure and temperature under different working environments, allowing the sealing ring to maintain good sealing performance within the specified range. This adaptability enables the sealing ring to work stably under various harsh conditions, improving the reliability and stability of the equipment.
[0022] The reinforcing mechanism includes a metal ring 502. A second annular groove 501 is provided inside the ring body 101. The metal ring 502 is inserted into the second annular groove 501. The metal ring 502 has high strength and hardness, which can effectively enhance the overall structure of the sealing ring and make the sealing ring able to withstand greater pressure and tension. The main sealing ring maintains a stable shape and performance under harsh environments such as high pressure and high temperature, thus extending the life of the sealing ring.
[0023] The top of the ring body 101 is fixedly connected to an extension ring 601. The inner diameter of the extension ring 601 matches the inner diameter of the ring body 101. The thickness of the ring body 101 is 0.3 mm to 0.8 mm, and the thickness of the extension ring 601 is 0.2 mm to 0.5 mm. The extension ring 601 allows the ring body 101 to be inserted into the hole when sealing it, facilitating the positioning of the ring body 101. If the sealing ring is fitted onto the outer wall of the shaft for sealing, the extension ring 601 can increase the contact area between the sealing ring and the shaft, improving the sealing effect of the sealing ring.
[0024] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
