Description

Technical Field

[0001] This utility model relates to the field of rubber seal technology, specifically a deformation-resistant rubber seal. Background Technology

[0002] Rubber seals are sealing components made of rubber materials, mainly used to prevent leakage of liquids, gases or dust, and to ensure the sealing performance of mechanical equipment. They are widely used in various machinery, pipelines, hydraulic systems and pneumatic systems to provide reliable sealing effects, prevent external contaminants from entering or internal fluids from leaking, thereby ensuring the normal operation and safe use of equipment.

[0003] During use, rubber seals are made of highly elastic and flexible materials. When exposed to factors such as temperature, pressure, and chemical corrosion, the molecular structure of the rubber changes, resulting in stretching, compression, or aging. This causes deformation, leading to the seals losing their original elasticity and shape, deforming or cracking, reducing their sealing performance, and even causing leaks, thus affecting the normal operation and safety of the equipment.

[0004] Therefore, this utility model provides a deformation-resistant rubber seal to solve the above problems. Utility Model Content

[0023] 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.

[0024] This utility model provides a deformation-resistant rubber seal, such as... Figures 1-4 As shown, a deformation-resistant rubber seal includes an outer protective layer 1. Both ends of the inner wall of the outer protective layer 1 are fixedly connected to connecting rings 2. The outer periphery of the opposite faces of the connecting rings 2 is fixedly connected to a reinforcing frame 3. The inner periphery of the opposite faces of the connecting rings 2 is fixedly connected to a thickening component. The opposite faces of the connecting rings 2 are provided with slots, and a widening component is engaged inside the slots.

[0025] The thickened component includes a sealing ring 4, with its upper and lower surfaces fixedly connected to the inner circumference of the opposite sides of the connecting rings 2 at both ends. A first retaining ring 5 is fixedly connected to the inner wall of the sealing ring 4, and an inner ring 6 is snapped onto the outer surface of the first retaining ring 5. A protruding ring 7 is fixedly connected to the inner wall of the inner ring 6. The inner ring 6 and the sealing ring 4 can be connected through the first retaining ring 5. By using a modular design, it is easy to quickly disassemble and replace individual structures of the seal, thereby reducing replacement costs. Furthermore, the inner ring 6 can improve the support performance of the middle structure of the seal, thereby enhancing its resistance to pressure and deformation. This effectively reduces deformation caused by pressure or temperature changes during use, maintains the original shape and sealing performance of the seal, and ensures the stability and reliability of the sealing effect.

[0026] The widening component includes a second retaining ring 8, the outer surface of which is engaged with the inside of the retaining groove. A widening pad 9 is fixedly connected to the upper surface of the second retaining ring 8, and an inner convex pad 10 is fixedly connected to the inner wall of the widening pad 9. The widening pad 9 can be connected to the connecting ring 2 through the second retaining ring 8, which facilitates the individual disassembly and replacement of the widening pad 9. The widening pad 9 can increase the contact area between the seal and the device, which helps to disperse pressure, improve the sealing effect, reduce local stress concentration, and further improve the reliability and durability of the seal.

[0027] The second retaining ring 8 is L-shaped and made of hard rubber. The second retaining ring 8 is fixed and has an L-shaped bottom end for limiting, which can securely connect the widened pad 9 and the connecting ring 2.

[0028] The inner circumference of the inner convex pad 10 is the same as that of the inner circumference of the convex ring 7. The outer circumference of the widened pad 9 is greater than that of the outer circumference of the outer sheath 1. The consistency of the inner circumference makes it convenient for the device to be fitted onto the outer periphery of the device, thereby reducing the complexity of operation. The widened pad 9 can increase the contact area between the outer sheath 1 and the device and distribute the force.

[0029] The reinforcing frame 3 is X-shaped, and there are several reinforcing frames 3, which are distributed at intervals along the outer periphery of the opposite face of the connecting ring 2. The reinforcing frame 3 can improve the compressive strength of the seal and further improve the deformation performance to prevent deformation.

[0030] Working steps: First, the inner ring 6 and the sealing ring 4 can be connected by the first retaining ring 5. The inner ring 6 can improve the support performance of the middle structure of the seal. Next, the reinforcing frame 3 can further improve the compressive strength of the seal. Second, the widening gasket 9 and the connecting ring 2 can be connected by the second retaining ring 8, which facilitates the individual disassembly and replacement of the widening gasket 9. Finally, the widening gasket 9 can increase the contact area between the seal and the device, which helps to distribute pressure.

[0031] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
