It can bring together various connection points in the electrical system for easy management and maintenance, and can clearly understand the direction of each circuit in the electrical system, determine the location and cause of the fault, so as to deal with it in time. At the same time, the junction box can also protect the circuit to prevent the circuit from malfunctioning due to overcurrent, short circuit and other reasons, which may cause damage to electrical equipment.

[0003] The container power station has a complex structure, and a variety of equipment is integrated inside. In order to facilitate external connection of various equipment in the container, the existing technology usually thinks of using a junction box to lead out and collect the interfaces of these equipment. The existing junction box is generally designed with a single-sided opening. When the back panel is opened, the assembler needs to use a screwdriver or a wrench to remove the screws or fixings on the back panel of the disassembly box, which makes it troublesome to disassemble the back panel, making it inconvenient to connect the equipment in the container. Therefore, the existing junction box is difficult to meet the wiring management needs of the container power station. Utility Model Content

[0004] The purpose of the utility model is to provide a detachable back plate structure of a junction box to solve the problem that the container power station proposed in the above background technology has a complex structure and various devices are integrated inside. In order to facilitate external connection of various devices in the container, the prior art usually thinks of using a junction box to lead out and collect the interfaces of these devices. The existing junction box is generally designed with a single-sided opening. When the back plate is opened, the assembler needs to use a screwdriver or a wrench to remove the screws or fixings on the back plate of the disassembly box, which makes the disassembly of the back plate more troublesome, thereby making it inconvenient to connect the wires in the container. Therefore, the existing junction box is difficult to meet the wiring management needs of the container power station.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0006] A detachable back plate structure of a junction box comprises a box body, wherein four corners of the box body are fixedly connected with mounting seats, the interior of the box body is fixedly provided with wiring terminals, two positioning holes are symmetrically provided on opposite side walls of the box body, a positioning frame is fixedly connected to the inner wall of the box body, a back plate cover is provided on the positioning frame, four plug-in posts which are plugged into the positioning holes are symmetrically and slidably connected to the back plate cover about its vertical center plane, the ends of the four plug-in posts are fixedly connected with sliding rods, and the outer sliding sleeve of the sliding rod is provided with a limiting ring which is fixedly connected to the back plate cover.

[0007] Furthermore, one end of a linkage rod is rotatably connected to the end of the sliding rod, the other end of the linkage rod is rotatably connected to a U-shaped seat, one end of a soft rope is fixedly connected to the side wall of the U-shaped seat, the other end of the soft rope is wound around a winding wheel, a rotating handle is fixedly connected to the central position of the winding wheel, and the rotating handle is rotatably connected to the back plate cover.

[0012] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0013] 1. By driving the winding wheel to rotate through the rotating handle, the winding wheel will wind the two soft ropes, and then the ends of the soft ropes will drive the two U-shaped seats to slide relatively close on the limiting rod. Thus, the U-shaped seats will drive the linkage rods at both ends to rotate, and the other end of the linkage rod will drive the sliding rod to slide in the limiting ring. In this way, the sliding rod will drive the insertion column to move out of the positioning hole on the box body. Therefore, the back plate of the junction box can be quickly disassembled, so that the wiring operation in the container can be facilitated, and the assembly worker can disassemble and assemble the back plate of the junction box without using tools.

[0014] 2. The return spring can pull the U-shaped seat to quickly reset, and then the U-shaped seat will drive the linkage rods at both ends to reset and rotate.

By fixedly arranging the sealing covers and cable ducts on the side walls of the box body, waterproof sealing treatment can be carried out at the wiring ports. By arranging the ventilation plates on the opposite side walls of the box body, the air exchange between the inside of the junction box and the outside can be facilitated, so as to facilitate the heat dissipation of the internal components. And the moisture absorption plate arranged therein can absorb the humid air inside the junction box, and the air passing through can also be filtered by the arranged dust filtering holes to prevent dust from entering the inside of the box body.
