Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0023] Reference Figures 1-2This utility model provides an embodiment of a single-phase brushless motor stator core, comprising a housing 1, a sleeve 2 slidably connected to the outer wall of the housing 1, a groove 3 formed on the inner wall of the sleeve 2, the outer wall of the housing 1 slidably connected to the inner wall of the groove 3, a first washer 4 slidably connected to the outer wall of the sleeve 2, a spring 5 fixedly connected to the outer wall of the first washer 4, a second washer 6 fixedly connected to the top of the spring 5, a first core 7 slidably connected to the outer wall of the second washer 6, and an mounting strip 9 fixedly connected to the outer wall of the first core 7. The first core 7 is further slidably connected to a second washer 6. Two iron cores 8, the inner wall of the second iron core 8 is provided with an installation groove 10, the outer wall of the installation strip 9 is slidably connected to the inner wall of the second iron core 8, the outer wall of the installation strip 9 is slidably connected to the inner wall of the installation groove 10, the inner walls of the second iron core 8 and the first iron core 7 are both slidably connected with guide strips 11, the outer walls of the second iron core 8 and the installation strip 9 are both slidably connected to the inner wall of the outer shell 1, and a support assembly is provided on the lower surface of the outer shell 1; the support assembly includes a support base 12, the upper surface of the support base 12 is slidably connected to the lower surface of the outer shell 1, and a base plate 13 is fixedly connected to the lower surface of the support base 12;

[0024] Specifically, the first washer 4 slides into the inner wall of the outer shell 1, is blocked by the sleeve 2, and the first iron core 7 drives the mounting strip 9 to slide into the inner wall of the second iron core 8 and the mounting groove 10, so as to quickly splice, install and fix the first iron core 7 and the second iron core 8.

[0025] Reference Figures 2-3 A first rotating shaft 14 is fixedly connected to the lower surface of the base plate 13, and a second rotating shaft 15 is rotatably connected to the inner wall of the first rotating shaft 14; a hydraulic cylinder 16 is fixedly connected to the outer wall of the second rotating shaft 15, and a third rotating shaft 17 is fixedly connected to the output end of the hydraulic cylinder 16; a push rod 18 is rotatably connected to the outer wall of the third rotating shaft 17, and a first limiting post 19 is rotatably connected to the inner wall of the push rod 18.

[0026] Specifically, the hydraulic cylinder 16 drives the third rotating shaft 17 to rotate on the inner wall of the push rod 18 under the limit of the second rotating shaft 15. The limit of the second rotating shaft 15 drives the connecting rod 20 to push under the limit of the first limit post 19. During use, it can drive the fixed block 22.

[0027] Reference Figure 3 A connecting rod 20 is fixedly connected to the outer wall of the first limiting post 19, and a second sliding post 21 is rotatably connected to the inner wall of the connecting rod 20; a fixing block 22 is fixedly connected to the outer wall of the second sliding post 21, and a limiting rod 23 is fixedly connected to the inner wall of the fixing block 22; a limiting shaft 24 is rotatably connected to the inner wall of the limiting shaft 23, and the outer wall of the limiting shaft 24 is rotatably connected to the inner wall of the first shaft 14.

[0028] Specifically, the second sliding column 21 and the limiting pivot 24 and the limiting rod 23 can make the fixing block 22 clamp the outer shell 1 more stably, which not only facilitates the installation of the first iron core 7 and the second iron core 8.

[0029] Working Principle: When the device is needed, it is installed by sliding the outer shell 1 into the inner wall of the sleeve 2 and the slide groove 3. During use, the sleeve 2 serves as the ventilation opening and shaft mounting point. The slide groove 3 further seals the outer shell 1. The first washer 4 slides into the inner wall of the outer shell 1 and is blocked by the sleeve 2. During use, the first iron core 7 drives the mounting strip 9 to slide into the inner wall of the second iron core 8 and the mounting groove 10. This allows for quick assembly and installation of the first and second iron cores 7 and 8. If the first and second iron cores 7 or 8 are damaged, they can be quickly replaced using the mounting strip 9 and the mounting groove 10. During transport, the second washer 6 and spring 5 prevent damage to the stator due to bumps before the rotor is installed. The hydraulic cylinder 16 drives the third rotating shaft 17 to rotate on the inner wall of the push rod 18 under the limit of the second rotating shaft 15. The limit of the second rotating shaft 15 drives the connecting rod 20 to push the fixing block 22 under the limit of the first limiting post 19. The limit of the second sliding post 21, the limiting rotating shaft 24 and the limiting rod 23 allows the fixing block 22 to clamp the outer shell 1 more stably during use. This not only facilitates the installation of the first iron core 7 and the second iron core 8, but also makes it easier to replace the internal structure by fixing the outer shell 1 during maintenance. During use, the stator iron core not only avoids damage caused by the first iron core 7 and the second iron core 8 hitting the inner wall of the outer shell 1 due to bumps during transportation and carrying, but also further increases the stability of the fixing block 22 during use.
