[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0022] Reference Figures 1-4 A highly sealed and leak-proof automobile water pump comprises a water pump body 1, a connecting pipe 2 is fixedly mounted on the upper end of the water pump body 1, and a plurality of L-shaped elastic plates 3 are fixedly mounted at equal intervals on the side of the connecting pipe 2. The elastic plates 3 are made of elastic material, have a certain elasticity, and can undergo elastic deformation.

[0023] A triangular block 5 is fixedly installed on the side of the elastic plate 3 away from the connecting pipe 2, and the inclined surface of the triangular block 5 faces the water pump body 1. A lifting ring 6 is provided on the connecting pipe 2, and the lifting ring 6 is located directly below the multiple triangular blocks 5. A first threaded sleeve 7 is fixedly installed on the upper surface of the lifting ring 6. A retaining ring 11 is provided above the connecting pipe 2, and a second threaded sleeve 8 is fixedly installed on the lower surface of the retaining ring 11. The second threaded sleeve 8 is engaged with the thread of the first threaded sleeve 7, and the inner diameter of the retaining ring 11 is smaller than the outer diameter of the connecting pipe 2.

[0024] When installing the water pipe, the retaining ring 11 is put on the water pipe, and then one end of the water pipe is expanded and put on the connecting pipe 2, and is between multiple elastic plates 3. Then, the upper end of the first threaded sleeve 7 is contacted with the lower end of the second threaded sleeve 8, so that the threads are engaged and rotated with each other. Under the action of the thread, the first threaded sleeve 7 drives the lifting ring 6 to move vertically upward, and the second threaded sleeve 8 drives the retaining ring 11 to move vertically downward. When the lifting ring 6 moves vertically upward, it will contact the triangular block 5 on the elastic plate 3. Under the action of the triangular block 5, the upper end of the elastic plate 3 is tilted and deformed toward the connecting pipe 2 until the upper end of the elastic plate 3 contacts the water pipe, thereby clamping the water pipe between the multiple elastic plates 3 and the connecting pipe 2. When the retaining ring 11 moves vertically downward, part of the water pipe will be squeezed between the upper end of the connecting pipe 2 and the retaining ring 11. During installation, no tools are required, the connection is convenient, and there will be no connection gap, which effectively prevents leakage and improves the sealing of the automobile water pump.

[0025] A triangular hook 4 is fixedly installed on the upper ends of multiple elastic plates 3. The distance between the triangular hook 4 and the connecting pipe 2 is smaller than the distance between the elastic plate 3 and the connecting pipe 2. An annular groove 9 is provided on the outer surface of the connecting pipe 2, and an annular sealing ring is sleeved in the groove 9.

[0026] When the upper end of the elastic plate 3 is tilted and deformed toward the water pipe, the triangular hook 4 will be driven to move toward the water pipe. When the triangular hook 4 contacts the water pipe, the contact portion will be deformed and move into the slot 9, thereby clamping the water pipe between the triangular hook 4 and the slot 9, which can effectively prevent the water pipe from falling off the connecting pipe 2 and provide better stability.

[0027] A guide ring 10 is fixedly installed on the upper end of the connecting pipe 2. The longitudinal section of the guide ring 10 is triangular. The inner diameter of the retaining ring 11 is larger than the inner diameter of the connecting pipe 2. The lower surface of the retaining ring 11 and the inner hole wall are fixedly installed with protective pads. The protective pads are rubber pads. When the water pipe is sleeved on the connecting pipe 2, the guide ring 10 contacts one end of the water pipe, which can facilitate the outward expansion of one end of the water pipe, thereby facilitating the water pipe to be sleeved on the connecting pipe 2.

[0028] A filter plate 12 is fixedly installed inside the connecting pipe 2. The filter plate 12 is provided with a plurality of filter holes. When the automobile water pump is in use, the filter plate 12 can filter the circulating water to prevent impurities in the water from entering the water pump and affecting the service life of the water pump.

[0029] When the cam 11 is moved vertically downwards, the lifting ring 6 is moved vertically upwards, and the second threaded sleeve 8 drives the cam 11 to move vertically downwards. When the lifting ring 6 moves vertically upwards, it contacts the triangular block 5 on the elastic plate 3. Under the action of the triangular block 5, the upper end of the elastic plate 3 is tilted and deformed toward the connecting pipe 2 until the upper end of the elastic plate 3 contacts the water pipe, thereby clamping the water pipe between the multiple elastic plates 3 and the connecting pipe 2. When the cam 11 moves vertically downwards, part of the water pipe is squeezed between the upper end of the connecting pipe 2 and the cam 11. During installation, no tools are required, the connection is convenient, and there is no connection gap, which effectively prevents leakage and improves the sealing performance of the automobile water pump.

[0030] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
