Figure 5 for Figure 4 The enlarged view at point A, Figure 6A schematic diagram of the cross-sectional structure of the connection between the support cylinder and the first piston rod provided in an embodiment of the present application. The mobile height-adjustable high and low voltage distribution cabinet equipment 100 includes a distribution cabinet body 110, a door body 130 is provided on one side of the distribution cabinet body 110, and a locking device is provided between the door body 130 and the distribution cabinet body 110. The above distribution cabinet body 110, the door body 130 and the locking device can all be provided using existing technology. Two adjustment devices 120 are provided on both sides of the door body 130 of the distribution cabinet body 110. The adjustment devices 120 can be close to the distribution cabinet body 110 in the retracted state to facilitate the transportation of the equipment. When the distribution cabinet body 110 needs to be erected for application, the distribution cabinet body 110 can be supported on the ground by the adjustment device 120. The adjustment device 120 includes a mounting plate 121 fixed to the side wall of the distribution cabinet body 110. An extension plate 122 is angled at one end of the mounting plate 121, facing away from the distribution cabinet body 110. The mounting plate 121 and extension plate 122 can be integrally formed, and the mounting plate 121 can be secured to the distribution cabinet body 110 through various methods, such as welding or screwing. A C-shaped support frame 123 is hingedly connected to the upper and lower ends of the extension plate 122. The C-shaped support frame 123 can be composed of three interconnected tubes. The extension plate 122 and the C-shaped support frame 123 together enclose a square storage chamber, which is used to tighten and wrap the multiple support cylinders 140 and support base 146 in their stored state, preventing them from expanding during transportation, thereby reducing the overall footprint of the device. Multiple support cylinders 140 are arranged within the storage chamber, with their head and tail ends alternately inverted, and the multiple support cylinders 140 are sequentially connected at their tail ends. Two U-shaped through grooves 141 are provided on the side surface of the rear end of the support cylinder 140. A first piston rod 142 is slidably provided inside the rear end of the support cylinder 140. A second piston rod 143 is fixed to the front end of the support cylinder 140. A load-bearing shaft 144 is horizontally passed through the first piston rod 142 and the second piston rod 143 and is rotatably provided. The ends of the two load-bearing shafts 144 at the two adjacent support cylinders 140 are commonly connected to two fixing blocks 145. The support cylinder 140 at the front end is fixed to the mounting plate 121. When the power distribution cabinet body 110 needs to be erected, the C-shaped support frame 123 is rotated and opened, and the support cylinder 140 at the rear end is rotated so that it is aligned with the support cylinder 140 at the front end. Then, the support cylinder 140 at the rear end is pushed so that the first piston rod 142 and the second piston rod 143 are both inserted into the inner cavity of the support cylinder 140 at the front end. During this action, the load-bearing shaft 144 will slide into the U-shaped through groove 141.Select a support tube 140 with a suitable number of sections and repeat the above operation. After removing the extra support tubes 140, adjust the angle of the support base 146 to complete the installation. (Since the support tube 140 at the tail end is connected to the support base 146 and the support tube 140 at the front end is fixedly connected to the mounting plate 121, the support tube 140 at the middle end is removed here. During the disassembly process, you only need to pull out the first piston rod 142 and the second piston rod 143 at the support tube 140 along its front end support tube 140 and insert the first piston rod 142 of its rear end support tube 140 into the above-mentioned front end support tube 140) A support tube 140 at the tail end is hinged with a support base 146. The hinge method between the support base 146 and the support tube 140 at the tail end can be connected by referring to the connection method between the two adjacent support tubes 140, and will not be elaborated here.

[0025] As can be seen from the above, in the embodiment of the present application, an adjustment device 120 is arranged on both sides of the distribution cabinet body 110, and the adjustment device 120 includes a C-shaped support frame 123, a mounting plate 121 and an extension plate 122, wherein the extension plate 122 and the C-shaped support frame 123 can be enclosed to form a storage cavity, and then a plurality of support cylinders 140 can be stored and clamped, so that during the transportation process, the support cylinder 140 can be locked in the above-mentioned storage cavity. On the other hand, in the present application, a support cylinder 140 is provided, and a first piston rod 142 and a second piston rod 143 are respectively provided at the head end and the tail end of the support cylinder 140, and both piston rods are hinged with a load-bearing shaft 144, and the load-bearing shafts 144 are connected by a fixed block 145, so that after the installation of the two adjacent support cylinders 140 is completed, the first piston rod 142 and the second piston rod 143 are both inserted into the head end support cylinder 140 and the load-bearing shaft 144 is in the U-shaped through groove 141, at this time, the stability of the connection end of each support cylinder 140 can be greatly improved, and its torsion in the horizontal direction can be limited.

[0026] In some embodiments, a partition 147 is provided within the inner cavity of the support cylinder 140, with a pre-set hole 123a defined at the central axis of the partition 147. A first piston rod 142 is connected to a stopper rod 148 at its central axis. The other end of the stopper rod 148 extends along the pre-set hole 123a to the top of the partition 147 and is then connected to a raised portion 149 having a diameter larger than the pre-set hole 123a. In this embodiment of the present application, through the above arrangement, when the first piston cylinder falls under the action of gravity, the raised portion 149 connected to the stopper rod 148 will be blocked by the pre-set hole 123a, thereby preventing the first piston cylinder from falling off the support cylinder 140 and being lost. It should be noted that in this embodiment of the present application, since the first piston cylinder cannot be pulled out of the support cylinder 140, the height of the distribution cabinet cannot be adjusted by increasing or decreasing the number of sections of the support cylinder 140. Instead, the height can be adjusted by configuring one of the support cylinders 140 as a cylinder or rod with an adjustable length.

[0027] In some embodiments, a movable plate 124 is provided on one side of a middle section of the C-shaped support frame 123 near the extension plate 122, and the movable plate 124 and the C-shaped support frame 123 are connected together by a plurality of springs 125. In the embodiment of the present application, through the above arrangement, when the support tubes 140 are in the storage state, the movable plate 124 is pressed to retract and compress the springs 125. After the multiple support tubes 140 and the support base 146 are completely placed in the storage chamber, the movable plate 124 is released. At this time, the movable plate 124 is tightly abutted against the side walls of the multiple support tubes 140 under the action of the springs 125, thereby pressing the support tubes 140 to prevent them from dispersing during transportation.

[0028] In some embodiments, a plurality of anti-skid protrusions are provided on the back of the support base 146. In the embodiment of the present application, the anti-skid protrusions are provided to enhance the anti-skid performance of the entire device.

[0029] In some embodiments, a handle device is provided on the top of the power distribution cabinet body 110. In the embodiment of the present application, the handle device is provided to facilitate lifting the entire device.

[0030] In some embodiments, a positioning hole is provided through the C-shaped support frame 123 at the position of the orthographic projection of the first support tube 140. In this embodiment of the present application, after the power distribution cabinet body 110 is installed and erected, the C-shaped support frame 123 can be rotated again to reset. At this time, due to the provision of the positioning hole, the C-shaped support frame 123 will not collide with the support tube 140 during the reset process, and will not be blocked by the support tube 140.

[0031] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit them. Although the present application has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some or all of the technical features therein. These modifications or replacements do not deviate the essence of the corresponding technical solutions from the scope of the technical solutions of the embodiments of the present application, and they should all be included in the scope of the claims and specification of the present application. In particular, as long as there is no structural conflict, the various technical features mentioned in the various embodiments can be combined in any way.
