[0020] Embodiment:

[0021] As Figures 1 to 4 shown, the present invention discloses a vacuum circuit breaker structure convenient for disassembly and assembly, which includes a vacuum circuit breaker body 1 and a bracket 2. The vacuum circuit breaker body 1 includes a box body 11, and a pole column 12 is arranged above the box body 11. In the present invention, fixed plates 13 are fixedly connected to both the left and right sides of the box body 11. The fixed plates 13 are used to abut against the upper side of the bracket 2, and screws 14 for fixing to the bracket 2 are arranged on the fixed plates 13. In addition, clamping plates 3 are arranged on both the front and rear sides of the box body 11 on the bracket 2, and a driving mechanism for controlling the clamping plates 3 to clamp and release the box body 11 is also arranged on the bracket 2.

[0022] Among them, the bracket 2 includes a support rod 21 located directly below the box body 11. The support rod 21 supports the box body 11, improving the structural strength of the vacuum circuit breaker body 1 placed on the bracket 2.

[0023] Furthermore, a vertical rod 31 is fixedly connected to the lower side of the clamping plate 3. A rotating seat 32 is fixedly connected to the middle of the vertical rod 31. A rotating shaft 4 is rotatably arranged on the rotating seat 32. Limit plates 41 are fixedly connected to both sides of the rotating seat 32 on the rotating shaft 4. The limit plates 41 are used to prevent the rotating seat 32 from sliding left and right relative to the rotating shaft 4. In addition, auxiliary frames 22 are fixedly connected to the two ends of the rotating shaft 4 on the support rod 21, and the two ends of the rotating shaft 4 are connected to the auxiliary frames 22. The auxiliary frames 22 also abut against the lower side of the box body 11. Among them, the driving mechanism is used to drive the vertical rod 31 to rotate around the rotating shaft 4.

[0024] Specifically, the driving mechanism includes a lead screw 51 and a nut seat 52. A support plate 23 is fixedly connected below the support rod 21. The lead screw 51 is rotatably connected to the support plate 23, and the upper end of the lead screw 51 is rotatably connected to the support rod 21. The nut seat 52 is in threaded fit with the lead screw 51. In addition, a connecting rod 53 is hinged to the lower end of the vertical rod 31, and the other end of the connecting rod 53 is hinged to the nut seat 52. Among them, the lower end of the lead screw 51 penetrates through the support plate 23 and is fixedly connected with a crank 54.

[0025] The bracket 2 of the present utility model is also fixed with a hoop 25. When the bracket 2 is installed on a cement pole as Figure 4 shown, the bracket 2 is fixed to the cement pole through the hoop 25. Then, when the vacuum circuit breaker body 1 needs to be installed on the bracket 2, first place the vacuum circuit breaker body 1 on the present utility model, and fix the fixing plates 13 on the left and right sides of the box body 11 to the bracket 2 through the screw 14. Then, rotate the lead screw 51 by the crank 54 to move the nut seat 52 upward. The nut seat 52 drives the vertical rod 31 to rotate around the rotating shaft 4 through the connecting rod 53, so that the clamping plate 3 moves towards the box body 11 to clamp the box body 11. When disassembling, first remove the screw 14 on the fixing plate 13, and then rotate the lead screw 51 by the crank 54 to move the nut seat 52 downward. The nut seat 52 drives the vertical rod 31 to rotate around the rotating shaft 4 through the connecting rod 53, so that the clamping plate 3 moves away from the box body 11 to loosen the box body 11. At this time, the vacuum circuit breaker body 1 can be removed. This structure can facilitate the staff to disassemble and assemble the vacuum circuit breaker body 1.

[0026] In the present utility model, in order to enable the clamping plate 3 to clamp the box body 11 more firmly, clamping openings 15 for the clamping plate 3 and the vertical rod 31 to enter are respectively provided on the front and rear sides of the box body 11 corresponding to the clamping plate 3. That is to say, when the clamping plate 3 clamps the box body 11, the clamping plate 3 is located in the clamping opening 15. This structure can effectively limit the position of the box body 11 and improve the clamping effect of the clamping plate 3 on the box body 11.

[0027] In the present utility model, limit blocks 24 are fixedly connected to the front and rear sides of the fixing plate 13 of the bracket 2. The limit blocks 24 facilitate preventing the vacuum circuit breaker body 1 from being in an accurate position, so that the screw 14 can be easily aligned with the threaded holes on the bracket 2.

[0028] At the same time, it should be pointed out that the terms used in the present utility model, such as: "front", "rear", "vertical", "horizontal", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it cannot be understood as a limitation on the protection scope of the present utility model.

[0029] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
