[0015] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings.

[0016] A preferred embodiment of the present invention, a prefabricated distribution cabinet for a power system, will be described in detail below, such as... Figures 1-4 As shown, a prefabricated distribution cabinet for a power system includes a rear panel 1, a door frame 2 on the front side of the rear panel 1, a door panel 3 hinged to the inner side of the door frame 2, and side panels 4 symmetrically hinged on the left and right sides between the rear panel 1 and the door frame 2. The side panels 4 are composed of two vertical plates that are hinged to each other. The ends of the left and right vertical plates that are far apart from each other are respectively hinged to the rear panel 1 and the door frame 2, so that the side panels 4 can be folded and retracted. The vertical plates are hinged to each other, as well as to the rear panel 1 and the door frame 2. The hinges between the left and right vertical plates and the rear panel 1 and the door frame 2 are located on the inner side, and the hinges between the two vertical plates that are hinged to each other are located on the outer side. Therefore, the side panels 4 can be retracted and folded by moving inward at the center.

[0017] The rear panel 1 has mounting holes 7 on both the left and right sides, and a hanging hole 8 at the center of the top of the rear panel 1. The power distribution cabinet can be installed through the mounting holes 7, and the power distribution cabinet can be temporarily suspended through the hanging hole 8.

[0018] Furthermore, such as Figures 4-7 As shown, sealing plate assemblies 5 are symmetrically arranged on the upper and lower sides of the rear end of the door frame 2, and sliding grooves 6 are symmetrically opened on the upper and lower sides of the rear plate 1. The sealing plate assembly 5 includes a fixing plate 51. The fixing plate 51 is symmetrically fixedly installed on the upper and lower sides of the rear end of the door frame 2. A folding plate 52 is hinged to the rear side of the fixing plate 51. The folding plate 52 is limited and slidably connected to the rear plate 1 through the sliding groove 6 and passes through the rear plate 1, so that the folding plate 52 can move back and forth in the sliding groove 6.

[0019] The folding plate 52 and the fixed plate 51 are hinged together by a hinge, and the hinges between the folding plate 52 and the fixed plate 51 are all located on the inside, so that the folding plates 52 on the upper and lower sides can be folded towards the center.

[0020] Extending columns 53 are symmetrically fixedly connected to the left and right ends of the rear side of the folding plate 52. Limiting blocks 54 are slidably connected inside the extending columns 53, and the limiting blocks 54 on both sides extend outward. A spring 55 is fixedly connected between the end of the limiting block 54 inside the extending column 53 and the inner wall of the extending column 53. Placement slots 56 are symmetrically opened on the upper and lower sides of the rear end of the rear plate 1. Limiting holes 57 are symmetrically opened on the left and right ends of the upper and lower sides of the placement slots 56, and the limiting holes 57 are adapted to the limiting blocks 54. The position of the folding plate 52 is limited by the cooperation of the limiting holes 57 and the limiting blocks 54.

[0021] The working principle of this utility model is as follows: During the temporary setup of the distribution cabinet, the fixed plate 51 and the folding plate 52 are in an extended state and extend forward. Through the design of the extension column 53 on the rear side of the folding plate 52, and the cooperation of the limiting block 54 inside the extension column 53 with the limiting hole 57 under the action of the spring 55, the position of the fixed plate 51 and the folding plate 52 can be limited, thereby keeping the fixed plate 51 and the folding plate 52 on the upper and lower sides in an extended state. At the same time, the side plates 4 on the left and right sides are also in an extended state. Thus, the combination of the side plates 4 and the fixed plate 51 and the folding plate 52 between the rear plate 1 and the door frame 2 can form a closed distribution cabinet. The design of the door panel 3 inside the door frame 2 enables the assembly and control of the power system.

[0022] After the distribution cabinet is assembled, it can be installed through the mounting hole 7, and temporarily suspended through the hanging hole 8, thus realizing the temporary construction of the distribution cabinet in the power system.

[0023] When the distribution cabinet needs to be disassembled, first remove the distribution cabinet, then push the left and right side plates 4 towards the middle, and at the same time push the door frame 2 backward, so that the folding plate 52 is released from the limit block 54 and the limit hole 57 and moves backward in the slide groove 6. At the same time, during the process of pushing the side plate 4 towards the middle, through the design of the two vertical plates of the side plate 4 being hinged to each other, and the hinges between the two sides of the side plate 4 and the back plate 1 and the door frame 2, the left and right side plates 4 can be retracted and folded inward. At the same time, after the folding plate 52 moves backward to the back side of the back plate 1, through the hinge between the folding plate 52 and the fixed plate 51, the upper and lower folding plates 52 can be folded towards the middle, so that the folding plate 52 can be folded and retracted into the placement groove 56, and the limit block 54 and the limit hole 57 are used again to complete the limit of the folding plate 52, thereby completing the folding and retraction of the distribution cabinet, which is convenient for loading and transfer.

[0024] When the distribution cabinet is to be used again, simply pull the door frame 2 forward to unfold the distribution cabinet for use. The operation is convenient and quick. At the same time, the distribution cabinet has an integrated design, so no parts will be lost during disassembly, assembly and transportation.
