[0002] The DC distribution cabinet is an intermediate device between the rectifier, battery and DC load in the DC power supply system, and has the functions of circuit conversion, protection, control, measurement and alarm signal issuance. The DC distribution cabinet can divide the total input DC into multiple paths, and each path has a protective device fuse, circuit breaker, lightning protection, etc., and can monitor the voltage and current of each path, and can communicate remotely.

[0003] A common power distribution cabinet is generally composed of a cabinet body, a cabinet door and a mounting frame. When in use, multiple groups of components are installed on the surface of the mounting frame and then wired. However, since the components are fixed in position after being installed by bolts in this method, they need to be dismantled as a whole before their position can be adjusted during wiring or adjustment. This can easily lead to insufficient wiring distance and the need to increase the line distance. At the same time, the maintenance process is time-consuming and laborious, and cannot meet the working requirements of the power distribution cabinet. For this reason, a DC power distribution cabinet is proposed. Utility Model Content

Figure 5, a mounting block 12 is connected to the left front portion of the connecting plate 6, and a mounting seat 13 is connected to the right front portion of the connecting plate 6;

[0030] The rotating shaft 14 is inserted into the inside of the mounting block 12, and the outside of the rotating shaft 14 is provided with a transmission block 15 through a bearing sleeve, and the upper and lower sides of the transmission block 15 are movably connected with a transmission arm 16 through a bearing, and a support plate 11 is installed on the front side of the second hinged ear 9. The inner side of the rotating shaft 14 is a threaded structure, and the inner side of the rotating shaft 14 is screwed to the inside of the mounting seat 13. The outer end of the rotating shaft 14 is equipped with a turntable, and the shape of the transmission arm 16 is an H-shaped setting. The inner end of the transmission arm 16 is sleeved on the outside of the connecting shaft 10. The length of the rotating shaft 14 is greater than the connecting plate 6. By rotating the rotating shaft 14 enables the transmission block 15 to drive the movement of the transmission arm 16, thereby driving the hinge rod 8 to swing left and right through the connecting shaft 10, so that the left and right position of the supporting plate 11 can be adjusted, which is convenient for quickly adjusting the left and right positions of the components after installation, avoiding the need to disassemble and assemble them individually, and improving the speed of wiring. In addition, since the hinge rod 8 drives the supporting plate 11 to move left and right, the supporting plate 11 will move forward for a distance, which facilitates better repair of the components during maintenance, and avoids the problem of inconvenience in maintenance caused by components being installed in a deeper position inside the cabinet 1.

[0031] See also Figure 1 The front part of the connecting frame 5 is provided with a card block 17, the number of the card blocks 17 is 8-12 groups, and the orientations of the card blocks 17 are all symmetrically arranged in pairs, see Figure 6 , the inner part of the block 17 is inserted with a limit block 18, and the outer end of the limit block 18 passes through the corresponding position of the card block 17, and the outer end of the limit block 18 is rounded, please refer to Figure 7 The inner ends of the limit blocks 18 are connected to springs 20, and the inner ends of the springs 20 are connected to the corresponding positions of the inner cavities of the clamping blocks 17.

Rubber pads are laid inside the card slots 19. By pressing the limit block 18, the card slots 19 inside the card block 17 and the limit block 18 overlap, so that the connecting wire can be inserted into the card slot 19, which is convenient for wiring the wires between components and avoids the wires from being entangled with each other.

[0032] The present solution enables the transmission block 15 to drive the movement of the transmission arm 16 by rotating the rotating shaft 14, thereby driving the hinged rod 8 to swing left and right through the connecting shaft 10, so that the left and right position of the supporting plate 11 can be adjusted, which facilitates the rapid adjustment of the left and right position of the components after installation, avoids the need to disassemble and assemble them individually, and improves the speed of wiring. In addition, because the hinged rod 8 causes the supporting plate 11 to move forward a certain distance when driving the supporting plate 11 to move left and right, it is convenient to better repair the components during maintenance, and avoids the problem of inconvenience in maintenance caused by components being installed in a deeper position inside the cabinet 1.
