Some switch cabinets have non-adjustable internal space and can only install functional units of some specific specifications. When installing functional units of different sizes, the internal space of the switch cabinet cannot be adjusted and they cannot be installed. At the same time, when installing functional units, the internal space cannot be adjusted, and sometimes it is necessary for workers to enter the inside of the cabinet to install the functional units, which reduces the practicality of the switch cabinet. Moreover, when installing functional units in some existing switch cabinets, it is necessary to turn multiple screws to install them, which is rather troublesome and reduces the installation efficiency.

[0020] Compared with the prior art, the advantages and positive effects of the present application are that

[0021] 1. In this application, when it is necessary to adjust the internal space of the switch cabinet, the turntable is rotated to drive the threaded rod to rotate. Since the first sliding cylinder can slide on the outer surface of the first support rod, the two second sliding cylinders can slide on the outer surfaces of the two second support plates respectively, and the two second sliding cylinders are respectively connected to the threaded cylinder and the first sliding cylinder. Therefore, when the threaded rod rotates, the threaded cylinder does not rotate with it and further moves back and forth on the outer surface of the threaded rod.

By rotating a plurality of threaded nails into the plurality of threaded holes on the two threaded nails, a plurality of fixing plates are fixed at different positions of the two long strips, and the two sliders can slide inside the two chutes, which facilitates the movement of the plurality of fixing plates. Further, the plurality of mounting plates can be moved. A plurality of functional units are installed on the plurality of mounting plates. Thus, the internal space of the switch cabinet can be adjusted, and functional units of different sizes can be installed. Moreover, when installing the functional units, the two long strips are moved to the cabinet door, which is convenient for workers to install and improves the practicability of the switch cabinet.

[0022] 2. In this application, when installing functional units inside the switch cabinet, the plurality of transmission rods can slide inside the plurality of mounting plates respectively. By pulling the plurality of pull rods, at this time, the functional unit is placed on any one of the bottom plates, and the plurality of pull rods are released. The elastic force generated by the plurality of springs pulls the mounting plates, and further transmits the force to the plurality of pressing plates through the plurality of pull rods. The plurality of limiting plates have a limiting effect on the movement of the plurality of pressing plates. Thus, the plurality of pressing plates clamp the functional unit on the plurality of mounting plates, completing the installation of the functional unit. The installation method is simple and improves the installation efficiency of the functional unit. BRIEF DESCRIPTION OF THE DRAWINGS

It should be noted that, without conflict, the embodiments of the present application and the features in the embodiments can be combined with each other.

[0029] In the following description, many specific details are set forth in order to fully understand the present application. However, the present application can also be implemented in other ways different from those described herein. Therefore, the present application is not limited by the specific embodiments disclosed in the following specification.

[0030] Embodiment 1, as Figures 1-4 shown, the present application provides a low-voltage complete switchgear with adjustable internal unit space, and the switchgear includes:

[0031] Cabinet body 1;

[0032] The threaded rod 201 is arranged on both sides of the inner wall of the cabinet body 1 through bearings, and a threaded barrel 202 is sleeved on the outer surface of the threaded rod 201. Because of the bearings, the threaded rod 201 can rotate. When the threaded rod 201 rotates, the threaded barrel 202 does not rotate with it, and the threaded barrel 202 moves back and forth on the outer surface of the threaded rod 201;

[0033] The first support rod 203 is arranged at the inner wall of the cabinet body 1, and a first sliding barrel 204 is movably sleeved on the outer surface of the first support rod 203, and the first sliding barrel 204 can slide on the outer surface of the first support rod 203;

[0034] The lower connecting plate 205 is arranged on the outer surfaces of the two threaded barrels 202. Through the lower connecting plate 205, when the threaded rod 201 rotates, the threaded barrel 202 does not rotate with it;

[0035] Two second support plates 206 are arranged on both sides of the inner wall of the cabinet body 1, and two second sliding barrels 207 are movably sleeved on the outer surfaces of the two second support plates 206 respectively, and the two second sliding barrels 207 can slide on the outer surfaces of the two second support plates 206 respectively;

[0036] The upper connecting plate 208 is arranged on the outer surfaces of two second sliding cylinders 207, and two strips 209 are arranged on one side of the upper connecting plate 208. The upper connecting plate 208 plays a supporting role for the two strips 209;

[0037] A plurality of threaded studs 210 are respectively threadedly embedded on one side of the two strips 209, and fixing plates 211 are movably sleeved on the outer surfaces of the plurality of threaded studs 210. By rotating the plurality of threaded studs 210, the plurality of fixing plates 211 are fixed, and further the functional unit is installed at different positions.

[0038] As Figures 1-4 shown, one side of the two strips 209 is arranged on one side of the lower connecting plate 205. A plurality of threaded holes are formed on one side of each of the two strips 209. A turntable 2 is arranged on one side of the threaded rod 201. The plurality of threaded holes formed in the strips 209 enable the threaded studs 210 to be rotatably fixed.

[0039] As Figures 1-4 shown, sliding blocks 212 are arranged on one side of each of the plurality of fixing plates 211. Slide grooves 213 are formed on the opposite sides of the two strips 209. One sides of the plurality of sliding blocks 212 are respectively movably arranged inside the two slide grooves 213.

[0040] As Figures 1-4 shown, the plurality of sliding blocks 212 are grouped in pairs of two. Mounting plates 3 are arranged on one side of each of the plurality of sliding blocks 212. Two transmission rods 301 are movably embedded on one side of each of the plurality of mounting plates 3. The plurality of transmission rods 301 can respectively move on one side of the plurality of mounting plates 3.

[0041] As Figures 1-4 shown, circular plates 302 are arranged on one side of each of the plurality of transmission rods 301. Pulling rods 304 are arranged on one side of each of the plurality of transmission rods 301. The plurality of pulling rods 304 facilitate the pulling of the plurality of transmission rods 301.

[0042] As Figures 1-4 shown, springs 303 are movably sleeved on the outer surfaces of the plurality of transmission rods 301. One sides of the plurality of springs 303 are respectively arranged on one side of the plurality of mounting plates 3. The plurality of springs 303 have elasticity.

[0043] As Figures 1-4 shown, pressing plates 305 are arranged on one side of each of the plurality of pulling rods 304. Two limiting plates 306 are arranged on one side of each of the plurality of pressing plates 305. The plurality of limiting plates 306 play a limiting role in the movement of the plurality of pressing plates 305.

[0044] As Figures 1-4 shown, bottom plates 307 are arranged on one side of each of the plurality of mounting plates 3. One sides of the plurality of pressing plates 305 are respectively movably arranged on one side of the plurality of bottom plates 307. The plurality of bottom plates 307 play a supporting role for the functional unit.

[0045] When it is necessary to adjust the internal space of the switch cabinet during use, rotate the turntable 2 to drive the threaded rod 201 to rotate. Since the first sliding cylinder 204 can slide on the outer surface of the first support rod 203, the two second sliding cylinders 207 can respectively slide on the outer surfaces of the two second support plates 206, and the two second sliding cylinders 207 are respectively connected to the threaded cylinder 202 and the first sliding cylinder 204. Thus, when the threaded rod 201 rotates, the threaded cylinder 202 does not rotate with it and further moves back and forth on the outer surface of the threaded rod 201. At this time, by controlling the rotation direction of the turntable 2, the moving direction of the threaded rod 201 is made, and further the two long strips 209 move in different directions. By screwing a plurality of threaded nails 210 into the plurality of threaded holes above the two threaded nails 210, a plurality of fixing plates 211 are fixed at different positions of the two long strips 209, and the two sliders 212 can slide inside the two chutes 213, facilitating the movement of the plurality of fixing plates 211. Further, the plurality of mounting plates 3 can be moved. Function units are installed on the plurality of mounting plates 3. Thus, the internal space of the switch cabinet can be adjusted, and function units of different sizes can be installed. And when installing the function units, move the two long strips 209 to the cabinet door, which is convenient for workers to install and improves the practicability of the switch cabinet. When installing function units inside the switch cabinet, the plurality of transmission rods 301 can respectively slide inside the plurality of mounting plates 3. By pulling the plurality of pull rods 304, at this time, place the function unit on any one of the bottom plates 307, release the plurality of pull rods 304, and the elastic force generated by the plurality of springs 303 pulls the mounting plates 3. Further, the force is transmitted to the plurality of pressing plates 305 through the plurality of pull rods 304. The plurality of limiting plates 306 have a limiting effect on the movement of the plurality of pressing plates 305. Thus, the plurality of pressing plates 305 clamp the function unit on the plurality of mounting plates 3, completing the installation of the function unit. The installation method is simple and improves the installation efficiency of the function unit.

[0046] The above are only the preferred embodiments of the application, and it is not a limitation to the present invention in other forms. Any person skilled in the art may use the technical content disclosed above to make changes or modifications into equivalent embodiments with equivalent changes and apply them to other fields. However, as long as it does not depart from the technical content of the technical solution of the present invention, any simple modification, equivalent change and modification made to the above embodiments based on the technical essence of the present invention still belong to the protection scope of the technical solution of the present invention.
