[0002] High and low voltage switchgear are core equipment used for power distribution, control and protection in power systems. They can be divided into high voltage switchgear and low voltage switchgear according to voltage level. The two have significant differences in function, structure, application scenarios and technical characteristics.

[0003] The prior art, disclosed in publication number CN214478825U, describes a high- and low-voltage switchgear that can be quickly fixed and disassembled. This addresses the problem that in practical use, high- and low-voltage switchgear has a long service life and often needs to be relocated, requiring frequent disassembly and reassembly. Existing connection structures are cumbersome to install and disassemble, causing inconvenience for later relocation work, reducing efficiency, and increasing relocation time. The newly proposed high- and low-voltage switchgear includes a cabinet body with a support plate on one side of the bottom. Bolts are threaded through the support plate at the four corners of its top. The cabinet body is connected to the support plate via a connecting plate. This invention has a reasonable structure, is easy to operate, improves disassembly and reassembly efficiency, and facilitates rapid disassembly and reassembly, reducing the time spent on disassembly and reassembly.

[0004] The top two sides of the aforementioned support plate are equipped with slide rails that are compatible with the slider.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Please see Figure 1-5 The present invention provides the following technical solution:

[0028] A disassembly and assembly structure for a high and low voltage switchgear includes a support device 1 and a support column 3. The high and low voltage switchgear body 2 is installed on the top of the support device 1, and the support column 3 is threadedly connected to the bottom of the support device 1.

[0029] The supporting device 1 includes a support platform 11, a rotating roller 12, a clamping assembly 13, a connecting block 14, and a connector 15. The connector 15 is slidably connected to the inner wall surface of the connecting block 14. The rotating roller 12 is installed on the inner wall surface of the support platform 11. The high and low voltage switchgear body 2 is slidably connected to the top surface of the rotating roller 12. The high and low voltage switchgear body 2 can move left and right on the surface of the rotating roller 12, which facilitates the disassembly and replacement of the high and low voltage switchgear body 2, making the disassembly of the high and low voltage switchgear body 2 quick and convenient. The clamping assembly 13 is slidably connected to the top surface of the support platform 11. The connecting block 14 is threadedly connected to the right end of the support platform 11. The support platform 11 is threadedly connected to the top of the support column 3. There are four support columns 3, which are distributed at the four corners of the support platform 11. The four support columns 3 can maintain the stability of the support platform 11.

[0030] The clamping assembly 13 includes a limiting unit and a clamping unit, which are arranged sequentially from the outside to the inside.

[0031] The limiting unit includes a clamping plate 131, a connecting block 14 slidably connected to the right end of the clamping plate 131, and a connector 15 inserted into the right end of the clamping plate 131. The connector 15 is inserted into the interior of the clamping plate 131 and the connecting block 14, thereby locking and fixing the clamping plate 131, making it easy to disassemble and replace the clamping plate 131, and making the replacement of the clamping plate 131 quick and convenient. A helical spring 137 is slidably connected inside the clamping plate 131, and a limiting threaded rod 136 is provided inside the helical spring 137.

[0032] The clamping unit includes a clamping plate 132, which is slidably connected to the inward surface of a clamping plate 131. The clamping plate 131 is slidably connected to the top surface of the support platform 11. The clamping plate 131 is movably connected to the bottom of the high and low voltage switchgear body 2. The clamping plate 131 and clamping plate 132 can clamp and fix the high and low voltage switchgear body 2, protecting its safety. A connecting rod 135 is fixedly connected to the right end of the clamping plate 132. The clamping plate 132 is movably connected to the bottom of the high and low voltage switchgear body 2. There are two clamping plates 132, distributed at the front and rear ends of the high and low voltage switchgear body 2. The two clamping plates 132 can clamp and fix the high and low voltage switchgear body 2. The high and low voltage switchgear body 2 is clamped and fixed, thereby determining the position of the high and low voltage switchgear body 2. A rectangular plate 133 is fixedly connected to the outward end of the connecting rod 135. A locking bolt 134 is connected to the internal thread of the rectangular plate 133. A connector 138 is fixedly connected to the right side surface of the clamping plate 132. A limiting threaded rod 136 is slidably connected to the inner wall surface of the connector 138. A helical spring 137 is installed on the inward side surface of the connector 138. The helical spring 137 and the limiting threaded rod 136 can limit the two clamping plates 132, making the disassembly of the clamping plates 132 quick and convenient, thereby increasing the service life of the device.

[0033] When in use, rotate the nut, and the nut will disengage from the limiting threaded rod 136 and the clamping plate 131. At this time, the compressed helical spring 137 will start to rebound, and the helical spring 137 can push the clamping plate 132 to move back and forth.

[0034] The clamping plate 132 can push the clamping plate 131 to move back and forth. The clamping plate 131 moves back and forth on the surface of the connecting block 14 through the plug 15, so that the clamping plate 131 is detached from the bottom of the high and low voltage switch body 2.

[0035] Then rotate the locking bolt 134, which rotates on the inner wall of the rectangular plate 133, loosening the connection between the rectangular plate 133 and the clamping plate 131.

[0036] Pull the clamping plate 132 to the left, and the clamping plate 132 will cause the limiting threaded rod 136 and the connecting rod 135 to move to the left on the inner wall surface of the clamping plate 131. The clamping plate 132 will slide on the inward side surface of the clamping plate 131, so that the clamping plate 132 can be disengaged from the clamping plate 131.

[0037] Pushing the high and low voltage switch body 2 causes the bottom of the high and low voltage switch body 2 to roll on the surface of the rotating roller 12, allowing the high and low voltage switch body 2 to move to the left. This enables the high and low voltage switch body 2 to be disassembled and replaced, making the replacement of the high and low voltage switch body 2 quick and convenient, thereby increasing the service life of the device.

[0038] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to the embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
