Specific implementation manner

[0020] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model.

[0021] The present utility model provides a technical solution: As Figures 1 to 5 shown, in this embodiment, a pump with good stability includes a motor 1 and a pump body 2. One end of the motor 1 close to the pump body 2 is fixedly connected with a first connecting plate 3. One end of the pump body 2 close to the motor 1 is fixedly connected with a second connecting plate 4. A plurality of connecting holes 6 are opened on the first connecting plate 3, and a plurality of fitting holes 7 are opened on the second connecting plate 4. The plurality of fitting holes 7 correspond to the plurality of connecting holes 6 one by one. Fixing bolts 5 are respectively slidably inserted into the plurality of connecting holes 6. The fixing bolts 5 are in threaded fit with the fitting holes 7. A hexagonal groove 19 is opened on the nut of the fixing bolt 5. A movable plate 8 is arranged between the first connecting plate 3 and the motor 1. The movable plate 8 is of an annular structure. One end of the movable plate 8 close to the first connecting plate 3 is fixedly connected with a plurality of anti-retreat columns 9. The plurality of anti-retreat columns 9 correspond to the plurality of fixing bolts 5 one by one. The anti-retreat column 9 is slidably fitted with the hexagonal groove 19. One end of the movable plate 8 and the motor 1 are movably connected through a reset mechanism.

[0022] Among them, the reset mechanism is composed of a guide rod 11 and a first spring 12. A plurality of guide rods 11 are fixedly connected to the end of the motor 1. The plurality of guide rods 11 are arranged in an annular array. The plurality of guide rods 11 respectively slide through the guide grooves 10 opened on the movable plate 8. The outer surface of the guide rod 11 is wound with a first spring 12. The two ends of the first spring 12 are respectively fixedly connected with the movable plate 8 and the motor 1.

[0023] The first spring 12 is always in a compressed state. Under the extrusion of the first spring 12, it can ensure that the anti-retreat column 9 on the movable plate 8 can be inserted into the hexagonal groove 19 of the fixing bolt 5.

[0024] Among them, the plurality of guide grooves 10 and the plurality of anti-retreat columns 9 are staggered.

[0025] In this way, it can be ensured that the guide rod 11 does not affect the installation and disassembly of the fixing bolt 5.

[0026] When disassembling and assembling the fixing bolt 5, to avoid interference of the anti-loosening post 9 with the disassembly and assembly work, the following design is made. A circular plate 13 is fixedly connected to the side wall of the motor 1 close to the movable plate 8. The inner diameter of the circular plate 13 is larger than the outer diameter of the movable plate 8, and the axes of the circular plate 13 and the movable plate 8 are the same. A limiting mechanism acting on the movable plate 8 is arranged on the circular plate 13.

[0027] Among them, the limiting mechanism is composed of a plurality of limiting components. The plurality of limiting components are distributed in a circular array. The limiting component is composed of a limiting rod 14, a limiting plate 15, a baffle plate 16, a second spring 17 and a fixing plate 18. The limiting plate 15 is sleeved on the limiting rod 14 and fixedly connected to the limiting rod 14. One end of the limiting rod 14 slides through the circular plate 13 and extends into the interior of the circular plate 13. A baffle plate 16 is slidably sleeved on the other end of the limiting rod 14. The baffle plate 16 is fixedly connected to the circular plate 13 through the fixing plate 18. A second spring 17 is fixedly connected between the baffle plate 16 and the limiting plate 15. The second spring 17 is wound around the outer surface of the limiting rod 14.

[0028] During use, the second spring 17 is always in a compressed state. Under the extrusion of the second spring 17, the limiting plate 15 will closely adhere to the outer wall of the circular plate 13, so that one end of the limiting rod 14 extends into the interior of the circular plate 13. By pulling the other end of the limiting rod 14, the limiting rod 14 can be pulled out of the interior of the circular plate 13. When disassembling and assembling the fixing bolt 5, the movable plate 8 can be pushed into the interior of the circular plate 13, and the movable plate 8 is limited by the limiting rod 14, ensuring that the anti-loosening post 9 on the movable plate 8 will not interfere with the disassembly and assembly of the fixing bolt 5. After the installation of the fixing bolt 5 is completed, by pulling the limiting rod 14 in the direction away from the circular plate 13, the restriction on the movable plate 8 can be released.

[0029] The present utility model provides a pump with good stability. The specific working principle is as follows:

[0030] During use, when the first connecting plate 3 of the motor 1 and the second connecting plate 4 of the pump body 2 are fixedly connected by the fixing bolt 5, under the extrusion of the first spring 12, the anti-loosening post 9 on the movable plate 8 is inserted into the hexagonal groove 19 of the fixing bolt 5, thereby ensuring that the installed fixing bolt 5 will not become loose, and further ensuring that the stability of the pump will not deteriorate.

[0031] When disassembling and assembling the fixing bolt 5, to avoid interference of the anti-loosening post 9 with the disassembly and assembly work, the movable plate 8 can be pushed into the interior of the circular plate 13, and the movable plate 8 is limited by the limiting rod 14, ensuring that the anti-loosening post 9 on the movable plate 8 will not interfere with the disassembly and assembly of the fixing bolt 5. After the installation of the fixing bolt 5 is completed, by pulling the limiting rod 14 in the direction away from the circular plate 13, the restriction on the movable plate 8 can be released.

[0032] Although embodiments of the present utility model have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present utility model. The scope of the present utility model is defined by the appended claims and their equivalents.
