Description

Technical Field

[0001] The utility model relates to the field of distribution boxes, in particular to a high and low voltage distribution box which is easy to repair. Background Art

[0002] High and low voltage distribution boxes are boxes made of steel to protect the normal operation of components. Their manufacturing materials are generally divided into hot-rolled steel plates and cold-rolled steel plates. Cold-rolled steel plates are softer than hot-rolled steel plates and are more suitable for the production of distribution boxes. High and low voltage distribution boxes are equipment used for power distribution, control, metering and cable connection, and they have the advantages of convenient combination, strong series and compact structure.

[0003] A large number of electronic components or devices are generally assembled in high and low voltage distribution boxes. Due to the limited space in the distribution box, these electronic components or devices are difficult to install and replace, which makes the installation, disassembly and maintenance of electronic components difficult. When repairing the distribution box, the tools used by maintenance personnel and some small parts generated by disassembling electronic components are not convenient to store, which affects the maintenance work and easily causes the loss of parts. Utility Model Content

Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments; based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0020] like Figure 1 and Figure 2As shown, a high and low voltage distribution box for easy maintenance includes a box body 1 and a box door 2 installed at the front end of the box body 1, supporting feet 3 are provided at the four corners of the bottom of the box body 1, a bearing plate 4 is movably installed inside the box body 1, and a plurality of mounting plates 5 for mounting electronic components are fixedly connected to the front end of the bearing plate 4, and the mounting plate 5 is a T-shaped plate.

[0021] like Figure 2 and Figure 3 As shown, two ear plates 10 are fixedly connected to the four corners inside the box body 1, a limit rod 11 penetrating the support plate 4 is fixedly connected between the two ear plates 10, a limit tube 12 sleeved on the outside of the limit rod 11 is fixedly connected to the rear end of the support plate 4, and two ear plates 2 13 are fixedly connected to the top of the box body 1, a screw rod 14 penetrating the support plate 4 is rotatably installed between the two ear plates 2 13, a hand wheel 15 is installed at the front end of the screw rod 14, and a nut 16 threadedly connected to the screw rod 14 is fixedly connected to the rear end of the support plate 4.

[0022] By rotating the screw rod 14 through the hand wheel 15, the nut 16 drives the load-bearing plate 4 to move, and the positions of the load-bearing plate 4 and the mounting plate 5 can be adjusted. When the load-bearing plate 4 moves, the limit cylinder 12 slides synchronously along the limit rod 11. Multiple limit cylinders 12 can ensure the horizontal movement of the load-bearing plate 4 and the mounting plate 5.

[0023] like Figure 2 and Figure 4 As shown, an observation window 6 is provided on the upper part of the box door 2, and a plurality of material trays 7 are rotatably installed on the inner side of the box door 2 below the observation window 6. Support bars 8 are symmetrically rotatably installed on both sides of the material tray 7 away from one end of the box door 2. A positioning block 9 for positioning the support bar 8 is provided on the inner side of the box door 2 below the material tray 7. The positioning block 9 is located on one side of the support bar 8, and a through hole is provided at the end of the support bar 8 away from the material tray 7.
