DETAILED DESCRIPTION
[0023] See also Figure 1-7 , a distribution box convenient for maintenance, comprising a frame 1, wherein an equipment mounting plate 2 is arranged inside the frame 1;
[0024] The frame 1 is used to install the enclosed components, and the equipment mounting plate 2 is used to install the control equipment.
[0025] Side closing plates 3 are hinged on both sides of the frame 1, a top closing plate 4 is hinged on the top of the frame 1, a bottom closing plate 5 is hinged on the bottom of the frame 1, a plurality of mounting shells 6 are fixed on the surface of the frame 1, the top of the mounting shell 6 is connected to two connecting shells 9, a movable wheel 8 is slidably connected to the inner wall of the mounting shell 6, a slider 7 is fixed on the top of the movable wheel 8, the surface of the slider 7 is fixedly connected to the surface of the equipment mounting plate 2, a first spring 10 is fixed on the inner wall of the connecting shell 9, a limiting block 11 is fixed at the bottom of the first spring 10, a positioning groove for matching the first spring 10 is provided on the top of the slider 7, a combination card plate 13 is fixed on the top of the top closing plate 4, a fixing rod is fixed on the surface of the combination card plate 13, a C-shaped plate 12 is fixed on the top of the frame 1, a limiting rod 16 runs through the surface of the C-shaped plate 12, a pull plate 15 is fixed on the top of the limiting rod 16, a second spring 14 is fixed on the bottom of the pull plate 15, and the bottom of the second spring 14 is fixedly connected to the top of the C-shaped plate 12;
[0026] When performing maintenance, the equipment mounting plate 2 can be pulled forward to drive the slider 7 and the movable wheel 8 to slide on the inner wall of the mounting shell 6. At this time, the limit block 11 is affected by the surface force of the slider 7 and moves upward, and when the slider 7 moves forward and contacts the inner wall of the mounting shell 6, the limit block 11 on the other side can enter the positioning groove on the top of the slider 7, so that the equipment mounting plate 2 can be limited. Through this design, the operator can inspect the equipment on the surface of the equipment mounting plate 2 without entering the interior of the frame 1. At the same time, the operator can also open the side closing plate 3, the top closing plate 4 and the bottom closing plate 5 to make the upper and lower sides and the left and right sides of the frame 1 open. This four-sided design can be used The opening design allows maintenance personnel to enter the interior of the frame 1 from any side, achieving 360-degree inspection and maintenance without blind spots. At the same time, when a fault occurs in a certain area, the distribution box can be quickly opened from the nearest side for emergency processing, shortening the time for fault detection and repair, improving the reliability of the power supply system, and making the distribution box more convenient to maintain. When the top closing plate 4 rotates upward, pull the pull plate 15 to stretch the second spring 14 so that the fixed rod on the surface of the combined card plate 13 can enter the inner side of the C-shaped plate 12, and then release the pull plate 15 to reset the second spring 14. At this time, the limit rod 16 can block the fixed rod so that the top closing plate 4 can be positioned, so that the top closing plate 4 will not close by itself.
[0027] Furthermore, the limit block 11 is arranged in a trapezoidal structure;
[0028] Setting the limit block 11 into a trapezoidal shape ensures that when the inclined surface of the limit block 11 contacts the top edge of the slider 7, the limit block 11 can force itself to move upward through its own surface.
[0029] Furthermore, a first fixing plate 17 is fixed on the upper surface of the side closing plate 3 and the upper surface of both sides of the frame 1, and a pin rod 18 penetrates through the surface of the first fixing plate 17;

[0032] By twisting the screw rod 20 into the second fixing plate 19 between the frame 1 and the surface of the bottom closing plate 5, the bottom closing plate 5 can be limited, thereby preventing the bottom closing plate 5 from opening downward by itself due to gravity.
[0033] Further, the first spring 10 is a compression spring, and the second spring 14 is a tension spring;
[0034] Selecting a compression spring as the first spring 10 ensures that the limit block 11 can always apply force to the top of the slider 7, thereby ensuring that the slider 7 can obtain a certain limiting effect, while selecting a tension spring as the second spring 14 ensures that the limit rod 16 can always be located on the inner side of the C-shaped plate 12.
[0035] Furthermore, a slide bar 21 is fixed to the inner wall of the mounting shell 6, and the slide bar 21 slides through the slider 7;
[0036] The slider 7 can slide on the surface of the slide rod 21 , so that the slider 7 can obtain a guiding effect, while preventing the slider 7 from being separated from the inside of the mounting shell 6 .
[0037] Furthermore, a telescopic rod 22 is fixed to the top of the limit block 11, and the top of the telescopic rod 22 is fixedly connected to the top of the connecting shell 9;
[0038] When the first spring 10 contracts, the telescopic rod 22 can also contract, so that the limiting block 11 can obtain a guiding effect, thereby preventing the first spring 10 from twisting and bending.
[0039] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
