[0023] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0024] Refer to Figure 1 and Figure 3, an embodiment provided by the present utility model: a motor housing assembly with a multiple sealing structure, including a mounting plate 1. A cavity 2 is formed inside the mounting plate 1. A fixing rod 3 is fixedly connected inside the cavity 2, so that the cavity 2 can provide a mounting position for the fixing rod 3. The left and right sides of the outer part of the fixing rod 3 are both slidably connected with engaging plates 4. Furthermore, the fixing rod 3 can make the engaging plates 4 slide more stably. A connecting plate 6 is fixedly connected to the adjacent sides of the two engaging plates 4.

[0025] Furthermore, when one of the engaging plates 4 moves, it will drive the other engaging plate 4 to move. A pulling plate 5 is fixedly connected to the right side of one of the engaging plates 4. Thus, pulling the pulling plate 5 can make the pulling plate 5 drive the engaging plate 4 to move. A first spring 7 is sleeved on the outer part of the fixing rod 3. One end of the first spring 7 is fixedly connected to the left side of one of the engaging plates 4. Therefore, when one of the engaging plates 4 moves, it will compress the first spring 7. The other end of the first spring 7 is fixedly connected to the left inner wall of the cavity 2. A support plate 8 is arranged on the top of the mounting plate 1. The left and right sides of the bottom of the support plate 8 are both fixedly connected with inserting plates 9. The bottom of the inserting plates 9 is slidably connected inside the cavity 2.

[0026] The bottom of the pulling plate 5 is slidably connected inside the cavity 2, so that the pulling plate 5 can move more stably. The bottom of the two inserting plates 9 is provided with engaging assemblies. The engaging assembly includes an engaging hole 10. The engaging hole 10 is opened at the bottom of the inserting plate 9. The left sides of the two engaging plates 4 are respectively engaged with the inside of the two engaging holes 10. Thus, the inserting plates 9 can be fixed inside the cavity 2 through the engagement between the engaging plates 4 and the engaging holes 10. A first housing 11 is fixedly connected to the top of the support plate 8. Furthermore, the support plate 8 can provide support for the first housing 11.

[0027] As Figure 1 and Figure 2 shown: A plurality of first fixing plates 12 are fixedly connected inside the first housing 11. A stator 13 is fixedly connected to the outer part of the first fixing plates 12. Furthermore, the first fixing plates 12 can provide support for the stator 13. A plurality of second fixing plates 14 are fixedly connected inside the first housing 11. A bearing 15 is fixedly connected to the outer part of the second fixing plates 14. Subsequently, the second fixing plates 14 can provide support for the bearing 15. A rotor 21 is rotatably connected to the middle of the bearing 15. Thus, the bearing 15 can make the rotor 21 rotate more stably. A second housing 16 is threadedly connected to the outer part of the first housing 11. Thus, the second housing 16 can conduct a preliminary seal on the inside of the device.

[0028] A sealing plate 17 is slidably connected inside the second housing 16. The rear side of the rotor 21 sequentially penetrates through the middle of the sealing plate 17 and the second housing 16 and extends outward, so that the rotor can output power to other structures. A plurality of force-bearing columns 18 are fixedly connected to the rear side of the sealing plate 17. Then, when the sealing plate 17 is stressed, it will drive the force-bearing columns 18 to move. The outside of the force-bearing column 18 is slidably connected with a receiving column 19, and the rear side of the receiving column 19 is fixedly connected to the rear inner wall of the second housing 16.

[0029] Thus, the second housing 16 can provide support for the receiving column 19. The front side of the sealing plate 17 is in contact with the rear side of the first housing 11. Thus, the first housing 11 will press the sealing plate 17. A second spring 20 is sleeved outside the receiving column 19. One end of the second spring 20 is fixedly connected to the rear side of the sealing plate 17, and the other end of the second spring 20 is fixedly connected to the rear inner wall of the second housing 16. Furthermore, when the sealing plate 17 moves, it will compress the second spring 20.

[0030] Compared with some existing technologies, the above content enables the device to achieve the effect of quickly installing and disassembling the device during use, so that the device can be quickly installed at the place where it needs to be used, which can increase the usage scenarios of the device, improve the usage flexibility of the device, and achieve the effect of sealing the inside of the device. And through multiple seals, the sealing effect of the device can be enhanced, and thus the stable operation of the motor can be ensured.

[0031] Working principle: First, when the device needs to be installed, the insertion plate 9 can be inserted into the cavity 2. At this time, the pulling plate 5 is pulled, so that the pulling plate 5 drives one of the engaging plates 4 to slide outside the fixing rod 3. Then, when the engaging plate 4 slides, it will drive the other engaging plate 4 to slide outside the fixing rod 3 through the connecting plate 6, so that the other engaging plate 4 can stretch the first spring 7. Thus, the insertion plate 9 can be completely inserted into the cavity 2. At this time, the pulling plate 5 is released. Under the restoring force of the first spring 7, one of the engaging plates 4 will be restored. Then, when the engaging plate 4 moves, it will drive the other engaging plate 4 to be restored through the connecting plate 6. Furthermore, when the other engaging plate 4 is restored, it will drive the pulling plate 5 to be restored. And at this time, the left sides of the two engaging plates 4 will be respectively engaged with the inside of the two engaging holes 10, so that the insertion plate 9 can be fixed inside the cavity 2. Then, the support plate 8 can be fixed on the top of the mounting plate 1 by fixing the insertion plate 9, completing the quick installation and disassembly of the device.

[0032] When sealing the device, since the second housing 16 and the first housing 11 are threadedly connected, only by rotating the second housing 16 can the second housing 16 perform the first seal on the first housing 11. During the process of rotating the second housing 16, the sealing plate 17 will gradually approach the first housing 11. Further, the first housing 11 will press the sealing plate 17, causing the sealing plate 17 to drive the force-bearing column 18 to move. Subsequently, the force-bearing column 18 will slide into the interior of the receiving column 19, so that the sealing plate 17 will compress the second spring 20. Under the restoring force of the second spring 20, the sealing plate 17 will be closely attached to the first housing 11. Further, the sealing plate 17 can perform the second seal on the first housing 11, thus completing the multiple seals of the device.

[0033] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
