Description

Technical Field

[0001] This utility model relates to the field of sealing rings, specifically to a special-shaped rubber sealing ring. Background Technology

[0002] A sealing ring is a ring-shaped elastic element used to fill the gap between two or more connected parts. Its main function is to prevent fluids (including liquids and gases) or solid particles from leaking between adjacent mating surfaces, while also providing some isolation against external contaminants. Sealing rings are typically made of rubber, plastic, metal, or other synthetic materials, and come in various shapes, such as O-rings, Y-rings, V-rings, X-rings, and custom shapes, to suit different sealing needs and working environments. Rubber sealing rings, due to their excellent elasticity and sealing performance, are commonly used in the automotive, machinery, aerospace, medical equipment, and food processing industries; while metal sealing rings maintain excellent stability and durability in high-temperature, high-pressure, or corrosive environments.

[0003] For equipment with irregular sealing shapes, special-shaped rubber seals are required. The dimensions of special-shaped rubber seals need to be more precise, otherwise it will lead to abnormal assembly between equipment, create gaps between equipment, affect use, and thus result in higher production costs for special-shaped rubber seals. Utility Model Content

[0004] The purpose of this utility model is to provide a non-standard rubber sealing ring, which aims to improve the problem that non-standard rubber sealing rings require more precise dimensional control, resulting in higher production costs.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A special-shaped rubber sealing ring includes a body, which includes a top surface, a bottom surface, an inner ring surface, and an outer ring surface. The top surface and the bottom surface are planes, and the inner ring surface and the outer ring surface are arc surfaces. The curvature of the inner ring surface is greater than or less than the curvature of the outer ring surface. A through cavity is formed in the body, and the cross-sectional shape of the through cavity is the same as the cross-sectional shape of the body.

[0007] Furthermore, elastic grooves are provided on both the top and bottom surfaces, and the elastic grooves are located on the vertical central axis of the cavity.

[0008] Furthermore, multiple sealing protrusions are provided on both the inner and outer ring surfaces, and the sealing protrusions are located on the horizontal central axis of the cavity.

[0009] Furthermore, the height of the sealing protrusion is greater than the height of the through cavity.

[0010] Furthermore, the outer surface of the sealing protrusion is a vertical plane.

[0011] Furthermore, sealing protrusions are provided on both the outer ring surface and / or the inner ring surface.

[0012] Furthermore, the depth of the elastic groove is less than or equal to the distance between the bottom of the elastic groove and the through cavity.

[0013] By adopting the above technical solution, this utility model has the following advantages compared with the prior art:

[0014] The top and bottom surfaces of the main body are designed as flat surfaces to improve the tightness of the fit between the main body and the equipment. A cavity is set inside the cup body. When the equipment is assembled, a force is applied to the top and bottom surfaces of the main body. The main body folds outward through the cavity, ensuring a tight connection between the equipment. At the same time, the outer and inner ring surfaces with different curvatures are designed to ensure a tight fit between one side and the equipment, thereby pushing the main body to the other side and ensuring a good sealing effect on both sides. The cavity improves the elasticity of the main body, and the outer and inner ring surfaces with different curvatures increase the adaptability of the main body, increase the dimensional margin, reduce production difficulty, and thus reduce costs.

[0026] Example 1

[0027] Please refer to Figure 1 and Figure 2 As shown, this embodiment provides a non-circular rubber sealing ring. The non-circular rubber sealing ring is characterized by comprising a body 1, which includes a top surface 13, a bottom surface 14, an inner ring surface 15, and an outer ring surface 16. The top surface 13 and bottom surface 14 are flat, while the inner ring surface 15 and outer ring surface 16 are curved surfaces. The curvature of the inner ring surface 15 is greater than or less than the curvature of the outer ring surface 16. A through cavity 12 is formed within the body 1, and the cross-sectional shape of the through cavity 12 is the same as the cross-sectional shape of the body 1. The body 1 is placed in a groove between devices to seal the connection points of the devices, and the shape of the body 1 matches the shape of the groove.

[0028] The top surface 13 and bottom surface 14 of the main body 1 are set as planes to improve the tightness of the fit between the main body 1 and the equipment. A cavity 12 is set inside the cup body. When the equipment is assembled, a force is applied to the top surface 13 and bottom surface 14 of the main body 1. The main body 1 folds outward through the cavity 12 to ensure the tightness of the connection between the equipment. At the same time, the outer ring surface 16 and inner ring surface 15 with different curvatures are set so that one side fits tightly with the equipment, thereby pushing the main body 1 to the other side to ensure a good sealing effect on both sides. The cavity 12 improves the elasticity of the main body 1 and the outer ring surface 16 and inner ring surface 15 with different curvatures increase the adaptability range of the main body 1, increase the dimensional margin, reduce the production difficulty, and thus reduce the cost.

[0029] Furthermore, elastic grooves 11 are provided on both the top surface 13 and the bottom surface 14, and the elastic grooves 11 are located on the vertical central axis of the cavity 12. The elastic grooves 11 provided on the top and bottom of the body 1 improve the elasticity of the upper and lower ends, so that the body 1 can be compressed higher and better; and the elastic grooves 11 are located on the vertical central axis of the cavity 12, so that the pressure on the top surface 13 and the bottom surface 14 can be better transmitted to both sides of the cavity 12, driving the middle part of the body 1 to fold outward and abut against the side wall of the groove of the equipment, so as to achieve a multi-directional abutment seal.

[0030] Furthermore, the depth of the elastic groove 11 is less than or equal to the distance between the bottom of the elastic groove 11 and the through cavity 12. Controlling the depth of the sealing groove to be less than or equal to the distance between the bottom of the elastic groove 11 and the through cavity 12 ensures the structural strength of the top and bottom of the body 1 located on both sides of the elastic groove 11, ensuring the tightness of the fit between the top and bottom of the body 1 and the equipment, and improving the sealing effect. Let the depth of the sealing groove be a, and the distance between the bottom of the elastic groove 11 and the through cavity 12 be b; in this embodiment, a equals b, but a can also be less than b.

[0031] In this embodiment, multiple sealing protrusions 2 are provided on both the inner annular surface 15 and the outer surface, and the sealing protrusions 2 are located on the horizontal central axis of the cavity 12. The elastic protrusions, positioned on the horizontal central axis of the cavity 12, effectively improve the structural strength of the body 1 in the vertical direction, ensuring that the top surface 13 and bottom surface 14 of the body 1 are tightly fitted with the equipment, thus improving the sealing effect. Furthermore, the height of the sealing protrusions 2 is greater than the height of the cavity 12; setting higher sealing protrusions 2 further enhances the structural strength of the body 1 in the vertical direction. Similarly, the height of the sealing protrusions 2 can also be less than or equal to the height of the cavity 12. In this embodiment, the outer surface of the sealing protrusions 2 is a vertical plane 21, increasing the contact area between the sealing protrusions 2 and the sidewall of the groove, thereby improving the sealing effect.

[0032] Example 2

[0033] Please refer to Figure 3 As shown, this embodiment provides a special-shaped rubber sealing ring, whose structure is the same as that of the special-shaped rubber sealing ring disclosed in Embodiment 1. The difference is that a sealing protrusion 3 is provided on both the outer ring surface 16 and / or the inner ring surface 15 of the body 1. In this embodiment, a sealing protrusion 2 is provided on both the outer ring surface 16 and the inner ring surface 15; similarly, a sealing protrusion 2 can be provided only on the outer ring surface 16 or only on the inner ring surface 15. The sealing protrusion 2 corresponds to the position of the connection gap between the equipment. The through cavity 12 improves the elasticity of the body 1. During the assembly process, the body 1 is squeezed, driving the sealing protrusion 2 to move outward and fit against the connection gap between the equipment, sealing the connection gap and further improving the overall sealing effect.

[0034] The above description is merely a preferred embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
