The side of the rolling wheel 21 extends a ring 23, and the extension ring 23 and the support rod 22 are threadedly connected. When the distribution cabinet needs to be moved, the operator only needs to rotate the support rod 22 so that the support rod 22 is retracted upward, and the rolling wheel 21 contacts the ground. After moving to the destination, the support rod 22 is continued to be rotated so that the support rod 22 moves downward, so that the bottom of the support rod 22 contacts the ground, and the rolling wheel 21 is relatively retracted upward. This is better than the prior art. When moving some small and medium-sized distribution cabinets, there is no need to use a crane, and the distribution cabinet can be directly moved using the rolling wheel 21.

[0033] On the basis of the above embodiment: a connecting plate 3 is provided on the rolling wheel 21, the lifting device 2 also includes a lifting plate 24 and a driver 25 for controlling the lifting and lowering of the lifting plate 24, the driver 25 is connected to a first pedal 4 for controlling the lifting plate 24 to rise upward and a second pedal 41 for controlling the lifting plate 24 to descend downward, the lifting plate 24 has an initial state and a supporting state for supporting the distribution cabinet body 1 upward.

[0034] The above specific improvements are: Figure 3 and Figure 4 As shown, the lifting device 2 includes a driver 25 and a lifting plate 24 driven by the driver 25. When the operator steps on the first pedal 4, the first pedal 4 will control the driver 25 to drive the lifting plate 24 to rise upward, thereby using the lifting plate 24 to prop up the distribution cabinet body 1. During the assembly process, the distribution cabinet is propped up to facilitate assembly by the staff, and the distribution cabinet is generally placed outdoors. When there is water accumulation outdoors, the height of the distribution cabinet body 1 can be adjusted by the lifting plate 24 to prevent water from entering the distribution cabinet body 1.

[0036] The above specific improvements are: Figure 5 and Figure 6 As shown, the lifting device 2 also includes a first support rod 241 and a second support rod 242 arranged crosswise, and the first support rod 241 and the second support rod 242 are provided with two groups, and the two groups of first support rods 241 and second support rods 242 are arranged opposite to each other. When the operator continuously steps on the first pedal 4, the driver 25 will drive the first support rod 241 to move from both sides to the middle. Since the first support rod 241 and the second support rod 242 are hinged, when the first support rod 241 moves from both sides to the middle, it will drive the second support rod 242 to move from both sides to the middle, thereby lifting the power distribution cabinet. The body 1 is propped up, and the lower ends of the first strut 241 and the second strut 242 are connected to the connecting plate 3. A first moving component 6 is provided between the first strut 241 and the connecting plate 3 to assist the first strut 241 in moving along the side of the connecting plate 3. A second moving component 7 is provided between the second strut 242 and the connecting plate 3 to assist the second strut 242 in moving along the side of the connecting plate 3. Through the setting of the first moving component 6 and the second moving component 7, when the operator steps on the first pedal 4, the first strut 241 and the second strut 242 can move better.

[0037] On the basis of the above embodiment: an avoidance groove 31 is provided in the middle position of the connecting plate 3, the first moving component 6 includes a first sliding block 61 provided on one side of the first support rod 241 or the avoidance groove 31 and a first sliding groove 62 provided on the other side and adapted to the first sliding block 61, the second moving component 7 includes a second sliding block 71 provided on one side of the second support rod 242 or the avoidance groove 31 and a second sliding groove 72 provided on the other side and adapted to the second sliding block 71.

[0038] The above specific improvements are: Figure 6As shown, an avoidance groove 31 is provided in the middle position of the connecting plate 3, and a first sliding groove 62 and a second sliding groove 72 are respectively provided on both sides of the avoidance groove 31. When the first pedal 4 is stepped down multiple times, the driver 25 will drive the first support rod 241 to move from both sides to the middle, and the first support rod 241 drives the second support rod 242 to move from both sides to the middle. First sliding blocks 61 are provided on both sides of the first support rod 241. The first sliding block 61 can slide back and forth in the first sliding groove 62. Similarly, the second sliding block 71 can also slide back and forth in the second sliding groove 72. The first sliding groove 62 and the second sliding groove 72 on the same side can be connected. Through the setting of the avoidance groove 31, the driver 25 can be effectively avoided, which facilitates the installation of the driver 25.

[0039] On the basis of the above embodiment: the driver 25 is a hydraulic cylinder 8 , the hydraulic cylinder 8 has an extension shaft 81 , a movable shaft 82 is connected to the side of the hydraulic cylinder 8 facing away from the extension shaft 81 , and the movable shaft 82 is linked to the first pedal 4 .

[0040] The above specific improvements are: Figure 6 The driver 25 is a hydraulic cylinder 8. When the first pedal 4 is stepped on, the movable shaft 82 is driven to move, and the extension shaft 81 on the hydraulic cylinder 8 is pushed out from the hydraulic cylinder 8, so that the extension shaft 81 pushes the movable shaft 82 to move, thereby driving the first support rod 241 to move from both sides of the connecting plate 3 to the middle.

[0041] On the basis of the above embodiment: a first connecting rod 9 is provided on both sides of the hydraulic cylinder 8, a second connecting rod 91 is provided at the first pedal 4, a third connecting rod 92 is provided at the second pedal 41, a connecting shaft 93 is provided at the connection between the first connecting rod 9 and the second connecting rod 91 and the second connecting rod 91, a pressure relief pipe 83 is connected to the hydraulic cylinder 8, and the pressure relief pipe 83 is connected to the second pedal 41.

[0042] The above specific improvements are: Figure 4As shown, the connecting shaft 93 hinges the first connecting rod 9, the second connecting rod 91 and the third connecting rod 92 together. When the first pedal 4 is stepped on, the second connecting rod 91 rotates, and the first connecting rod 9 is driven to rotate through the connecting shaft 93. The first connecting rod 9 drives the movable shaft 8 to move, thereby driving the hydraulic cylinder 8 to move, and finally drives the extension shaft 81 on the hydraulic cylinder 8 to extend outward. The extension shaft 81 drives the first support rod 241 and the second support rod 242 to move through the connecting block 51, and finally drives the distribution cabinet body 1 to move upward. When the second pedal 41 is stepped on, the pressure relief pipe 83 drives the hydraulic cylinder 8 to return to its initial position. The hydraulic cylinder 8 can be purchased from a third-party company and is existing technology. Therefore, the principle of the movable shaft 82 driving the extension shaft 81 on the hydraulic cylinder 8 to move and how to return to the initial position will not be described in detail here.

[0043] On the basis of the above embodiment: a return spring 84 is sleeved on the exterior of the extension shaft 81 and the movable shaft 82 , and an abutting piece 85 capable of abutting against the return spring 84 is provided on the movable shaft 82 .

[0044] The above-mentioned specific improvements are as follows: when the pressure inside the hydraulic cylinder 8 is released, the piston inside the hydraulic cylinder 8 will drive the piston inside the hydraulic cylinder 8 to move to the initial position due to the elastic restoring force of the reset spring 84 mounted on the movable shaft 82. Therefore, through the setting of the reset spring 84, the hydraulic cylinder 8 can be assisted to return to the initial position, and through the setting of the abutment plate 85, the position of the reset spring 84 can be effectively positioned, so that the reset spring 84 maintains the elastic restoring force.

[0045] On the basis of the above embodiment: a heat dissipation slot 94 is provided on the power distribution cabinet body 1 , and a first extension plate 95 and a second extension plate 96 are provided at the heat dissipation slot 94 , which are arranged opposite to each other and are used to prevent rainwater from entering the power distribution cabinet body 1 .

[0046] The above specific improvements are: Figure 7 As shown, the equipment in the distribution cabinet will generate a lot of heat during operation. In order to effectively dissipate the heat, a heat dissipation groove 94 is opened on the distribution cabinet body 1. Then, since the distribution cabinets are mostly placed outdoors, some rainwater can easily enter the distribution cabinet body 1 through the heat dissipation groove 94. In order to solve this technical problem, a first extension plate 95 and a second extension plate 96 arranged opposite to each other are provided on the heat dissipation groove 94. The first extension plate 95 extends outward. The first extension plate 95 is arranged above the heat dissipation groove 94 to initially block rainwater from entering the distribution cabinet body 1. The second extension plate 96 extends toward the inside of the heat dissipation groove 94 and is arranged tilted upward to achieve a double effect of preventing rainwater from entering the heat dissipation groove 94, thereby greatly improving the waterproof ability of the heat dissipation groove 94.

[0047] On the basis of the above embodiment: the bottom of the power distribution cabinet body 1 is provided with an exhaust hole 97 for discharging the heat inside the power distribution cabinet body 1.

[0048] The above-mentioned specific improvement is that air convection is formed between the exhaust holes 97 and the heat dissipation slots 94, which can effectively discharge the heat inside the power distribution cabinet body 1 to the outside.

[0049] Obviously, the above embodiments are merely examples for clarity of explanation and are not intended to limit the implementation methods. Those skilled in the art will readily appreciate that other variations or modifications based on the above descriptions are possible.
