The reliability of a water pump is directly related to the proper operation of the engine. Its structure typically consists of a pump casing, impeller, bearings, and seals. With the rapid development of the automotive industry, the performance and reliability requirements of water pumps are constantly increasing. During maintenance and repair, water pump removal and installation are common operations.

[0003] Currently, the installation and removal of automotive water pumps are usually performed using manual tools combined with mechanical assistance. Common methods include fixing the water pump to the engine with bolts, loosening the bolts with a manual wrench or power tool, and then removing the water pump. However, the junction between the water pump and the engine often has problems such as small space and tight connection, making the disassembly process complicated and time-consuming. In addition, some maintenance personnel will also use methods such as crowbars or hammers to assist in disassembly, but this method can easily cause damage to the water pump or the engine body, affecting the quality of maintenance. Therefore, a disassembly mechanism for automotive water pumps is proposed to solve the above problems. Utility Model Content

[0004] In order to make up for the above shortcomings, the utility model provides a disassembly mechanism for an automobile water pump, aiming to improve the problem in the prior art that the water pump is installed on the automobile by bolts, which makes it inconvenient to disassemble.

[0033] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0034] Reference Figures 1-4The utility model provides an embodiment: a disassembly mechanism for an automobile water pump, comprising a pump body 1 and a base 2, wherein the pump body 1 is arranged on the top of the base 2, the pump body 1 and the base 2 are connected by a quick-release mechanism, and a jacking mechanism is arranged inside the base 2; the quick-release mechanism comprises a clamping block 10, which is fixedly connected to the bottom of the pump body 1, a limit block 11 is fixedly connected to the side wall of the clamping block 10, a clamping groove 12 is provided on the side wall of the clamping block 10, a sleeve 3 is fixedly connected to the top of the base 2, a limit groove 4 is provided inside the sleeve 3, and the sleeve A groove 5 is provided inside the cylinder 3, a limiting bead 6 is provided inside the groove 5, a slip ring 7 is slidably connected to the outside of the base 2, an inner ring 8 is fixedly connected to the inside of the slip ring 7, the inner ring 8 is slidably connected to the outside of the sleeve 3, a spring 9 is sleeved on the outside of the sleeve 3, one end of the spring 9 is fixedly connected to the side wall of the base 2, and the other end of the spring 9 is fixedly connected to the side wall of the inner ring 8, the side wall of the clamping block 10 is slidably connected to the inside of the sleeve 3, the limiting block 11 is slidably connected to the inside of the limiting groove 4, and the limiting bead 6 is slidably connected to the inside of the clamping groove 12;

[0035] When installing the pump body 1, first fix the base 2 on the car, then manually slide the slip ring 7 downward, using the force it brings to squeeze the spring 9, thereby releasing the limit bead 6, then insert the block 10 connected to the bottom of the pump body 1 into the interior of the sleeve 3, and at the same time insert the limit block 11 into the interior of the sleeve 3, which plays a role in firmly restricting the block 10, preventing the component from loosening or shifting, and improving the reliability of the installation. After the insertion is completed, the slip ring 7 can be released in time. At this time, the spring 9 quickly resets due to the loss of pressure, driving the slip ring 7 to push upward, achieving an automatic reset effect. At the same time, the inner ring 8 now covers the outside of the groove 5, firmly restricting the limit bead 6 inside the groove 5, so that the limit bead 6 is accurately stuck in the interior of the card slot 12, completing the entire installation. This operation process not only ensures the firm fixation of the block 10, but also greatly improves the overall stability of the pump body 1, effectively avoiding possible loosening during operation.

[0036] Reference Figure 5-Figure 6 The jacking mechanism includes a top plate 13, a sleeve 3 is arranged inside the sleeve 3, a hinged frame 2 16 is fixedly connected to the bottom of the sleeve 3, a hinged frame 15 is fixedly connected to the top of the base 2, a rotating plate 17 is rotatably connected to the inside of the hinged frame 15, a rotating plate 2 18 is rotatably connected to the inside of the hinged frame 15, a rotating shaft 19 is fixedly connected to the inside of the rotating plate 2 18, one side of the rotating plate 17 is rotatably connected to the side wall of the rotating shaft 19, a torsion spring 20 is sleeved on the outside of the rotating shaft 19, one end of the torsion spring 20 is fixedly connected to the side wall of the rotating plate 17, and the other end of the torsion spring 20 is fixedly connected to the side wall of the rotating plate 2 18, and a spring 2 14 is fixedly connected between the top plate 13 and the base 2.

[0037] As the block 10 is inserted downward, its continuous downward pressure exerts a certain amount of compression on the top plate 13, causing it to begin to slide downward. As the top plate 13 slides downward, one side of the turn plate 17 rotates under the support of the hinge frame 2 16, while the other side rotates via the rotating shaft 19. As the top plate 13 continues to move downward, the turn plate 2 18 begins to rotate within the hinge frame 15. This action generates a torsional torque. In particular, when the turn plates 17 and 18 deflect simultaneously, the torsion spring 20 and the spring 2 14 undergo significant deformation, storing a large amount of elastic potential energy, providing the necessary reaction force for the disassembly process. When the pump body 1 needs to be disassembled, the position of the limit bead 6 is released by sliding the slip ring 7 downward. At this time, the torsion spring 20 and the spring 2 14 lose pressure and immediately reset, causing the accumulated elastic potential energy to be released. Ultimately, the pump body 1 is lifted upward, completing the disassembly of the pump body 1. This process not only reduces the labor intensity of manual disassembly, but also effectively improves the disassembly efficiency, achieving labor-saving, fast and precise results.

[0038] Working principle: When installing the pump body 1, slide the slip ring 7 downward to squeeze the spring 1-9 to release the limiting bead 6, then insert the block 10 connected to the bottom of the pump body 1 into the inside of the sleeve 3, and insert the limiting block 11 into the inside of the limiting groove 4 to restrict the block 10. After the insertion is completed, release the slip ring 7. At this time, the spring 1-9 loses pressure and resets, pushing the slip ring 7 upward so that the inner ring 8 covers the outside of the groove 5, restricting the limiting bead 6 inside the groove 5, and making the limiting bead 6 stuck in the inside of the card groove 12, thereby completing the fixation of the block 10;

[0039] During the process of inserting the block 10 downward, the top plate 13 will be squeezed to make it slide downward. While the top plate 13 slides, one side of the rotating plate 17 will rotate in the hinge frame 2 16, and the other side will rotate on the rotating shaft 19. As the top plate 13 continues to move downward, the rotating plate 2 18 will rotate inside the hinge frame 15. When the rotating plates 17 and 2 18 are deflected at the same time, the torsion spring 20 will be deformed, and the spring 2 14 will be squeezed and contracted to store elastic potential energy. When the pump body 1 needs to be disassembled, the slip ring 7 is slid downward to release the lock of the limit bead 6. The torsion spring 20 and the spring 2 14 lose pressure and reset, and the pump body 1 can be lifted upward, thereby achieving the effect of assisting the disassembly of the pump body 1 and making the disassembly process more labor-saving.

[0040] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
