[0045] The distribution box provided by the utility model, which is easy to maintain, has the following working process when in use:

[0046] In order to make the maintenance of the distribution box more convenient, the existing method of fixing the relay 7 and the connector in the cabinet 1 by snap-fit ​​connection is improved to provide a sliding mechanism 4 inside the cabinet 1, that is, a plurality of slide grooves 41 are installed in sequence from top to bottom on both sides of the inner wall of the cabinet 1, and each two symmetrical slide grooves 41 form a group, and a connecting rod 42 is provided between each group of slide grooves 41. In order to make the connecting rod 42 slide on the slide groove 41, sliders 44 are fixedly installed at both ends of the connecting rod 42, respectively, and then the two sliders 44 are slidably connected with a group of slide grooves 41, so that the connecting rod 42 can move back and forth between a group of slide grooves 41;

[0047] A connecting frame 43 is fixedly installed on the front of the connecting rod 42, and a through slot 5 is respectively opened at the center position of the connecting rod 42 and the connecting frame 43. Then, when the back of the relay 7 is hung on the connecting frame 43, a threaded hole 8 is opened at the center position of the back of each relay 7. Bolts 9 are inserted on the back of the connecting rod 42 to make the bolts 9 pass through the through slots 5 of the connecting rod 42 and the connecting frame 43 and be threadedly connected with the threaded holes 8 on the back of the relay 7, so that the relay 7 is fixedly installed on the connecting frame 43. Compared with the existing connection method of the hook and the slot of the relay 7 and the connecting frame 43, when it is disassembled, it is not affected by the multiple relays 7 being squeezed and installed together side by side, and the disassembly is not difficult, but it is more labor-saving. Then, by pulling the connecting frame 43, the connecting rod 42 is driven to move on the slide slot 41, so that when the relay 7 is repaired and disassembled, the activity space is larger and the maintenance personnel can operate more conveniently.

[0048] At the same time, in order to fix the position of the connecting rod 42 on the slide groove 41, sockets 6 are respectively opened at both ends of the connecting rod 42, and at the tail end of each slide groove 41, that is, near the position of the second cabinet door 3, a socket 6 is opened horizontally, and on the outer walls of both sides of the cabinet 1, also near the second cabinet door 3 and at the position corresponding to the socket 6 on the slide groove 41, a plug rod 10 is installed through it, and the plug rod 10 is inserted into the slide groove 41 and the socket 6 of the connecting rod 42 to fix the position of the connecting rod 42. Due to the connection and fixing method of the plug rod 10 and the socket 6, and the simple connection method, when the connecting rod 42 needs to be moved later, the operation is simple. It only needs to pull out the corresponding plug rods 10 on both sides of the cabinet 1, and the connecting rod 42 can be pulled to move at will. The position of the connecting rod 42 is moved, and the position of the components such as the relay 7 on the connecting frame 43 is driven to move, so that it is convenient to repair it near the position of the first cabinet door 2.

[0049] The above only describes some exemplary embodiments of the present invention by way of illustration. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention.
