[0025] like Figures 3 to 5 As shown, in another embodiment of the utility model, the base 1 includes a base body 101, a third slide groove 102 is provided on the base body 101, a sliding cover plate 103 is provided in the third slide groove 102, a fourth slide groove 104 is provided on an outer wall of one side of the base body 101, and a first limiting slot 105 and a second limiting slot 106 are provided on an inner wall of one side of the fourth slide groove 104;

[0026] The fourth slide groove 104 is provided with a slider 107, and the slider 107 is provided with a fifth slide groove 108. A limit block 109 is slidably provided in the fifth slide groove 108, and a buckle groove 1010 is provided on the limit block 109. When a three-way connection is required, the limit block 109 is firstly made to leave the first limit slot 105 through the buckle groove 1010 and completely enter the fifth slide groove 108, and then the slider 107 is moved along the trajectory of the fourth slide groove 104, and the slider 107 drives the sliding sealing plate 103 to move, thereby releasing the sealing of the sliding sealing plate 103 to the third through groove 4, so that the third through groove 4 is connected with the second through groove 3, and the change It is formed into a three-way shape to perform a three-way connection, and at the same time, the slider 107 is moved to the second limit slot 106, and then one end of the limit plug 109 is inserted into the second limit slot 106 through the buckle slot 1010, so as to fix the position of the slider 107 at this time, and then the slider 107 is used to fix the position of the sliding cover 103. When a vertical connection is required, repeat the above steps, and then connect the second through slot 3 or the third through slot 4 to the cooling water pump. At this time, after the cooling water enters from the second through slot 3 or the third through slot 4, it will squeeze the cover 10 in the direction close to the first through slot 2, and the first through slot 2 is closed by the cover 10, thereby performing a vertical connection.

[0027] The working principle of the vehicle cooling water pump connecting the water pipe head:

[0028] When in use, first when a double-way connection is required, the first through groove 2 is connected to the cooling water pump, and the second through groove 3 is connected to the designated equipment. Then the cooling water pump injects cooling water into the first through groove 2. The cooling water in the first through groove 2 squeezes the sealing plate 10, causing the sealing plate 10 to move away from the first through groove 2, thereby releasing the sealing plate 10 from the first through groove 2. At the same time, the sealing plate 10 drives the guide slide column 8 and the limit slider 7. The guide slide column 8 and the limit slider 7 are used to limit the moving direction and position of the sealing plate 10. The spring 9 contracts, and then the cooling water enters the second through groove 3, and then enters the designated equipment through the second through groove 3. When the designated equipment suddenly has backflow, the backflow impacts the sealing plate 10, causing the sealing plate 10 to move closer to the first through groove 2, thereby using the sealing plate 10 to re-close the first through groove 2 to prevent backflow from passing through. The first through groove 2 enters the cooling water pump, causing damage to the cooling water pump. When a three-way connection is required, the limit plug 109 is allowed to leave the first limit slot 105 through the buckle groove 1010 and completely enter the fifth slide groove 108. Then the sliding plate 107 is used to release the closure of the third through groove 4 by the sliding cover 103, so that the third through groove 4 and the second through groove 3 are interconnected to form a three-way shape, thereby performing a three-way connection. When a vertical connection is required, repeat the above steps, and then connect the second through groove 3 or the third through groove 4 to the cooling water pump. At this time, after the cooling water enters from the second through groove 3 or the third through groove 4, it will squeeze the cover 10 in the direction close to the first through groove 2, and use the cover 10 to close the first through groove 2, thereby performing a vertical connection. The connection method itself can be changed accordingly according to actual conditions.

[0029] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not limitations on the implementation methods of the present invention. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made on the basis of the above description. It is impossible to list all the implementation methods here. All obvious changes or modifications derived from the technical solution of the present invention are still within the scope of protection of the present invention.
