[0029] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0030] Please refer to Figure 1 - Figure 8 , a vacuum adsorption sealed rubber ring for an automobile water tank, including a base 1, a support plate 2 is installed on the top of the base 1, a vacuum pump 3 is fixedly assembled in the inner cavity of the support plate 2, a guide air pipe 6 is installed on the top of the vacuum pump 3, a suction assembly 5 is arranged on the top of the base 1, a sealing assembly 4 is arranged on the outer wall of the guide air pipe 6, and a connecting pipe seat 7 is installed on the top of the base 1;

[0031] In the above structure, through the support plate 2 arranged on the top of the base 1 and the vacuum pump 3 arranged in the inner cavity of the support plate 2, the inner cavity of the sealing seat 501 can be evacuated under the action of the vacuum pump 3. During the air extraction process, under the action of the atmospheric pressure, the movement of the sealing ring 504 can be promoted, so that the sealing ring 504 fits on the inner wall of the connecting pipe seat 7 under the action of the air pressure, realizing the installation and fixation of the sealing ring 504, ensuring that during its installation process, manual installation is not required, thus avoiding scratches on the outer wall of the sealing ring 504.

[0032] In a preferred embodiment: The sealing assembly 4 includes a fixed cylinder 401, a limiting rod 402 is fixedly assembled on the inner wall of the fixed cylinder 401, a support spring 403 is movably sleeved on the outer wall of the limiting rod 402, a moving plate 404 is movably sleeved on the outer wall of the limiting rod 402, a plugging plate 405 is fixedly assembled on the outer wall of the moving plate 404, and a fixed pipe 8 is fixedly assembled on the outer wall of the fixed cylinder 401;

[0033] In the above structure, through the fixed cylinder 401 installed on the outer wall of the guide air pipe 6, when the vacuum pump 3 evacuates air, the movement of the plugging plate 405 will be promoted under the action of the air pressure, so that the plugging plate 405 moves towards the end close to the guide air pipe 6. When the outer wall of the plugging plate 405 moves into the inner cavity of the fixed cylinder 401, at this time, the inner cavity of the connecting groove 503 will be communicated with the inner cavity of the guide air pipe 6, and the air in the inner cavity of the sealing seat 501 will be adsorbed through the connecting groove 503 and the air guide groove 502, thus forming a negative pressure state.

[0034] In a preferred embodiment: Both ends of the support spring 403 are in contact with the inner wall of the fixed cylinder 401 and the outer wall of the moving plate 404 respectively, and the support spring 403 is made of high-carbon steel. The outer wall diameter of the plugging plate 405 is smaller than the inner wall diameter of the fixed cylinder 401;

[0035] In the above structure, through the support spring 403 provided, under the support and drive of the support spring 403, the moving plate 404 is attached to the inner wall of the fixed cylinder 401, so that the sealing plate 405 enters the inner cavity of the fixed pipe 8 to seal the inner cavity of the fixed pipe 8. When continuous air extraction is carried out under the action of the vacuum pump 3, the sealing plate 405 will move continuously and compress the support spring 403. When the vacuum pump 3 stops air extraction, the sealing plate 405 will be driven again under the action of the support spring 403, so that the sealing plate 405 enters the inner cavity of the fixed pipe 8. At this time, the inner cavities of the connecting groove 503 and the air guide groove 502 are kept in a negative pressure state, so that the sealing ring 504 can be continuously driven under the action of the atmospheric pressure, and thus the sealing ring 504 can be better installed on the inner wall of the connecting pipe seat 7.

[0036] In a preferred embodiment: The suction assembly 5 includes a sealing seat 501. A sealing column 509 is fixedly assembled in the inner cavity of the sealing seat 501. A connecting groove 503 is formed in the inner cavity of the sealing column 509, and an air guide groove 502 is formed in the inner cavity of the sealing column 509. A sealing ring 504 is installed in the inner cavity of the sealing seat 501;

[0037] In the above structure, by sleeving the connecting pipe seat 7 in the inner cavity of the sealing seat 501, the sealing column 509 enters the inner cavity of the connecting pipe seat 7, and the auxiliary plate 507 is attached to the outer wall of the sealing seat 501. Then the adjusting nut 508 is rotated. Under the action of the adjusting nut 508, the position of the threaded rod 506 is adjusted, so that the auxiliary plate 507 can fix the connecting pipe seat 7, thus realizing the installation and fixation of the connecting pipe seat 7. Subsequently, the inner cavities of the connecting groove 503 and the air guide groove 502 can be evacuated under the action of the vacuum pump 3. As the gas is continuously extracted, the sealing ring 504 can move under the action of the air pressure, and the installation of the sealing ring 504 can be realized under the action of vacuum adsorption.

[0038] In a preferred embodiment: A fixing plate 505 is fixedly assembled on the outer wall of the sealing seat 501. A threaded rod 506 is movably sleeved in the inner cavity of the fixing plate 505. An auxiliary plate 507 is fixedly assembled on the outer wall of the threaded rod 506. The threaded rod 506 is threadedly connected with an adjusting nut 508;

[0039] In the above structure, through the adjusting nut 508 provided on the outer wall of the threaded rod 506, when the adjusting nut 508 is rotated, the position of the threaded rod 506 is adjusted under the action of the adjusting nut 508, and the connecting pipe seat 7 can be fixed by the threaded rod 506 and the auxiliary plate 507, so that the connecting pipe seat 7 can be installed in the sealing seat 501.

[0040] In a preferred embodiment: The inner cavity of the connecting groove 503 communicates with the inner cavities of the fixed pipe 8 and the air guide groove 502 respectively. There are four auxiliary plates 507, and the four auxiliary plates 507 are respectively installed on the outer side of the sealing seat 501;

[0041] In the above structure, through the plugging column 509 provided on the inner wall of the sealing seat 501, when the connecting pipe seat 7 is docked with the sealing seat 501, the plugging column 509 enters the inner cavity of the connecting pipe seat 7. At this time, under the action of the plugging column 509, a cavity is formed between the inner cavity of the connecting pipe seat 7 and the inner cavity of the sealing seat 501, and at this time, the inner cavity of the air guide groove 502 can communicate with the formed cavity. Subsequently, under the action of the vacuum pump 3, the air in the formed cavity can be evacuated, and under the action of the atmospheric pressure, the movement of the sealing ring 504 is promoted, so that the sealing ring 504 can be installed on the inner wall of the connecting pipe seat 7.

[0042] In a preferred embodiment: One end of the air guide pipe 6 away from the vacuum pump 3 communicates with the fixed cylinder 401, and one end of the fixed pipe 8 away from the fixed cylinder 401 is connected to the outer wall of the sealing seat 501;

[0043] In the above structure, through the air guide pipe 6 provided on the top of the vacuum pump 3, the closed assembly 4 and the vacuum pump 3 are connected under the action of the air guide pipe 6, and the fixed cylinder 401 and the sealing seat 501 are connected under the action of the fixed pipe 8. Thus, under the action of the vacuum pump 3, the gas in the inner cavities of the air guide groove 502 and the connecting groove 503 is extracted. Under the action of the negative pressure, the sealing ring 504 is fitted and installed on the inner wall of the connecting pipe seat 7.

[0044] In a preferred embodiment: The inner wall diameter of the connecting pipe seat 7 matches the outer wall diameter of the plugging column 509, and the inner wall diameter of the fixed pipe 8 is equal to the outer wall diameter of the plugging plate 405;

[0045] In the above structure, through the plugging plate 405 installed on the outer wall of the moving plate 404, when air is evacuated under the action of the vacuum pump 3, the air in the inner cavity of the sealing seat 501 can be sucked, so that the sealing ring 504 moves towards the inner cavity of the connecting pipe seat 7 under the action of the negative pressure until the outer wall of the sealing ring 504 fits with the inner wall of the connecting pipe seat 7. At this time, the vacuum pump 3 stops evacuating. Under the action of the plugging plate 405, the inner cavity of the fixed pipe 8 is blocked, so that the inner cavity of the sealing seat 501 maintains a continuous negative pressure state, and the sealing ring 504 fits more tightly on the inner wall of the connecting pipe seat 7.

[0046] In a preferred embodiment: The inner wall diameter of the fixing plate 505 matches the outer wall diameter of the threaded rod 506, and both the threaded rod 506 and the auxiliary plate 507 are made of high carbon steel;

[0047] In the above structure, through the auxiliary plate 507 provided on the outer wall of the threaded rod 506, by adjusting the position of the threaded rod 506, the outer wall of the auxiliary plate 507 is attached to the outer wall of the connecting pipe seat 7, so that the connecting pipe seat 7 is installed and fixed in the inner cavity of the sealing seat 501. Thus, under the action of the vacuum pump 3, the inner cavity of the sealing seat 501 is suctioned to achieve a negative pressure state, ensuring that the sealing ring 504 fits on the inner wall of the connecting pipe seat 7.

[0048] In a preferred embodiment: the inner wall shape of the support plate 2 matches the outer wall shape of the vacuum pump 3, and the support plate 2 is made of stainless steel;

[0049] In the above structure, through the support plate 2 provided on the top of the base 1, the vacuum pump 3 can be fixed under the action of the support plate 2, ensuring that the vacuum pump 3 can be stably fixed on the top of the base 1. Furthermore, under the action of the vacuum pump 3, the installation of the sealing ring 504 is assisted to ensure that the sealing ring 504 can be installed in the inner cavity of the connecting pipe seat 7.

[0050] Working principle: During the use of the above device, when it is necessary to install the sealing ring 504 into the inner cavity of the connecting pipe socket 7, the outer wall of the connecting pipe socket 7 is inserted into the inner cavity of the sealing seat 501. At this time, the position of the auxiliary plate 507 is adjusted so that the outer wall of the auxiliary plate 507 fits against the outer wall of the connecting pipe socket 7. Subsequently, the adjusting nut 508 is rotated. At this time, the position of the threaded rod 506 can be restricted under the action of the adjusting nut 508, so that the outer wall of the auxiliary plate 507 fits against the outer wall of the connecting pipe socket 7, thereby realizing the fixation of the connecting pipe socket 7. At this time, the plugging column 509 will enter the inner cavity of the connecting pipe socket 7. At this time, a cavity can be formed under the action of the inner wall of the sealing seat 501 and the outer wall of the auxiliary plate 507. Subsequently, the vacuum pump 3 is started. Under the action of the vacuum pump 3, under the action of negative pressure, the plugging plate 405 moves out of the inner cavity of the fixed pipe 8, and the moving plate 404 moves along with the movement of the plugging plate 405 and compresses the support spring 403, so that the inner cavities of the fixed pipe 8, the sealing assembly 4 and the air guide pipe 6 are communicated. Under the action of the vacuum pump 3, the air in the inner cavities of the connecting groove 503 and the air guide groove 502 is sucked, so that the air in the cavity is pumped out. Under the action of negative pressure, the sealing ring 504 is attracted, so that the sealing ring 504 moves along the outer wall of the plugging column 509. Under the continuous suction action of the vacuum pump 3, the sealing ring 504 continuously moves along the outer wall of the plugging column 509 until the outer wall of the sealing ring 504 fits against the inner wall of the connecting pipe socket 7. When the vacuum pump 3 stops sucking, the moving plate 404 is driven under the action of the support spring 403, so that the plugging plate 405 enters the inner cavity of the fixed pipe 8 again to seal the inner cavity of the fixed pipe 8, so that the cavity between the inner wall of the sealing seat 501 and the outer wall of the auxiliary plate 507 continuously maintains a negative pressure state, enabling the sealing ring 504 to continuously approach the inner wall of the connecting pipe socket 7, completing the installation of the sealing ring 504. At this time, the connecting pipe socket 7 can be assembled in the water tank to realize the sealing of the water tank.
