Description

Technical Field

[0001] The utility model relates to the field of rubber pads, in particular to a rubber pad capable of enhancing durability. Background Art

[0002] A rubber gasket is a cushion-like sealing element made of rubber, typically used to fill gaps between two connected components to prevent the leakage of fluids, gases, or solid particles. Rubber gaskets are elastic and wear-resistant, adapting to varying operating conditions such as temperature, pressure, and movement. They are commonly used in joints in machinery, automobiles, pipelines, valves, and other applications to ensure the integrity and safety of the device.

[0003] As a key sealing component, rubber gaskets are widely used across various industries due to their ability to prevent leaks, reduce vibration and sound insulation, resist corrosion and wear, adapt to a variety of operating conditions, and ensure safe and reliable operation. They play an important role in maintaining system integrity and improving equipment performance. Due to their unique elasticity and sealing properties, rubber gaskets are widely used in various applications requiring leak prevention, vibration and sound insulation, corrosion and wear resistance, and adaptability to diverse operating conditions.

[0004] During long-term use, the existing rubber pads will be deformed when squeezed by external vibrations. Frequent deformation will reduce the service life of the rubber pads. As a result, the rubber pads used in pipe connection applications need to be replaced frequently, which is inconvenient during use.

[0024] The present invention will now be further described with reference to the accompanying drawings and specific embodiments. Figures 1-4 As shown, the rubber pad with enhanced durability according to the embodiment of the present invention includes a bottom rubber pad 1, a connecting member 2 is provided on the top outer side of the bottom rubber pad 1, a limiting member 3 cooperating with the bottom rubber pad 1 is provided on the inner bottom end of the connecting member 2, a top rubber pad 4 cooperating with the connecting member 2 is provided on the outer side of the limiting member 3, and a buffer member 1 5 cooperating with the connecting member 2 is provided on the inner bottom end of the top rubber pad 4; a buffer member 2 6 cooperating with the limiting member 3 is provided on the inner top end of the bottom rubber pad 1; a protective mask 1 7 cooperating with the top rubber pad 4 is provided on the outer side of the bottom rubber pad 1; and a protective mask 2 8 cooperating with the bottom rubber pad 1 is provided on the inner side of the top rubber pad 4.

[0025] With the help of the above technical solution, the utility model can fill the gap between the two connecting parts under the cooperation of the bottom rubber pad 1, the top rubber pad 4, the buffer part 1 5 and the buffer part 2 6 to prevent the leakage of fluid, gas or solid particles. Through the cooperation of the buffer part 1 5 and the buffer part 2 6, the influence of external vibration on the bottom rubber pad 1 and the top rubber pad 4 can be reduced, thereby enhancing the service life and durability of the bottom rubber pad 1 and the top rubber pad 4; under the cooperation of the connecting part 2, the limit part 3, the buffer part 1 5 and the buffer part 2 6, when the bottom rubber pad 1 and the top rubber pad 4 are squeezed by external vibration, the deformation of the bottom rubber pad 1 and the top rubber pad 4 will be reduced, and the influence of the vibration on the bottom rubber pad 1 and the top rubber pad 4 will be reduced, thereby enhancing the durability of the bottom rubber pad 1 and the top rubber pad 4 and reducing the frequency of replacement.

[0026] In one embodiment, for the above-mentioned connecting member 2, the connecting member 2 includes a support ring 201 arranged on the outer side of the top of the bottom rubber pad 1, and a plurality of limiting protrusions 202 are evenly arranged on the side of the support ring 201 close to the bottom rubber pad 1, and the plurality of limiting protrusions 202 are all in the same horizontal plane; thereby ensuring the stability of the connection between the bottom rubber pad 1 and the top rubber pad 4.

[0027] In one embodiment, for the above-mentioned limiting member 3, the limiting member 3 includes a support ring 2 301 arranged on the inner side of the bottom of the top rubber pad 4, and a plurality of limiting grooves 302 respectively matched with the plurality of limiting protrusions 202 are evenly arranged on the side of the support ring 2 301 close to the top rubber pad 4; the cross-sections of the bottom rubber pad 1, the support ring 1 201, the support ring 2 301 and the top rubber pad 4 are all L-shaped; thereby ensuring that no rotation occurs between the bottom rubber pad 1 and the top rubber pad 4.

[0028] In one embodiment, for the above-mentioned buffer member 1 5, the buffer member 1 5 includes a plurality of telescopic rods 501 evenly arranged at the bottom end of the top rubber pad 4 and matched with the connecting member 2, and a spring 502 is provided on the outside of the thin rods in the telescopic rods 501; the buffer member 2 6 has the same structure as the buffer member 1 5; thereby reducing the deformation generated by the bottom rubber pad 1 and the top rubber pad 4.

[0029] The working principle of buffer 5 is as follows:

[0030] When the bottom rubber pad 1 and the top rubber pad 4 are squeezed by external vibration, the support ring 1 201 in the connecting member 2 and the support ring 2 301 in the limiting member 3 move away from each other. In the process of the support ring 1 201 and the support ring 2 301 moving away from each other, the telescopic rod 501 in the buffer member 1 5 is shortened. Under the shortening action of the telescopic rod 501, the spring 502 is squeezed, and at the same time, under the restoring action of the spring 502, the telescopic rod 501 obtains an extension force. The extension force of the telescopic rod 501 offsets part of the force generated by the vibration, thereby reducing the impact of the vibration on the bottom rubber pad 1 and the top rubber pad 4.

[0031] In order to facilitate understanding of the above technical solutions of the present invention, the working principle or operation method of the present invention in actual process is described in detail below.

[0032] In actual application, the bottom end of the bottom rubber pad 1 and the top end of the top rubber pad 4 are respectively in contact with the two connecting parts, and with the cooperation of the protective mask 1 7 and the protective mask 2 8, the sealing effect between the two connecting parts is completed to avoid leakage of fluid, gas or solid particles; when the two connecting parts vibrate due to external reasons, the bottom rubber pad 1 and the top rubber pad 4 will be squeezed. During the squeezing process, the support ring 1 201 in the connecting part 2 and the support ring 2 301 in the limiting part 3 are moved away from each other through the cooperation of the buffer 1 5 and the buffer 2 6, thereby reducing the deformation of the bottom rubber pad 1 and the top rubber pad 4 caused by squeezing. At the same time, the limiting protrusion 202 in the connecting part 2 will move along the limiting groove 302 in the limiting part 3, thereby avoiding relative rotation of the bottom rubber pad 1 and the top rubber pad 4, thereby enhancing the stability and durability of the structure between the bottom rubber pad 1 and the top rubber pad 4.

[0033] The working principle of buffer 5 is as described above.

[0034] To sum up, with the help of the above-mentioned technical scheme of the present invention, the present invention can fill the gap between the two connecting parts under the cooperation of the bottom rubber pad 1, the top rubber pad 4, the buffer part 1 5 and the buffer part 2 6 to prevent the leakage of fluid, gas or solid particles. Through the cooperation of the buffer part 1 5 and the buffer part 2 6, the influence of external vibration on the bottom rubber pad 1 and the top rubber pad 4 can be reduced, thereby enhancing the service life and durability of the bottom rubber pad 1 and the top rubber pad 4; under the cooperation of the connecting part 2, the limit part 3, the buffer part 1 5 and the buffer part 2 6, when the bottom rubber pad 1 and the top rubber pad 4 are squeezed by external vibration, the deformation of the bottom rubber pad 1 and the top rubber pad 4 will be reduced, and the influence of the vibration on the bottom rubber pad 1 and the top rubber pad 4 will be reduced, thereby enhancing the durability of the bottom rubber pad 1 and the top rubber pad 4 and reducing the frequency of replacement.
