[0021] The utility model is further described in detail below in conjunction with the accompanying drawings.

[0022] See attached Figures 1 to 4The low-voltage switch cabinet carrier of the utility model comprises a plurality of vertically extending columns 1, and the plurality of columns 1 are installed together with a transversely extending crossbar 2 to form a frame structure. A rolling unit 4 is provided below the column 1, and the rolling unit 4 is rotatably installed below the column 1, and the carrier can be conveniently moved by pushing it. A plurality of shelves 3 are installed transversely on the column 1, and the plurality of shelves 3 are installed on the column 1 in parallel and at intervals. The upper and lower shelves 3 and the column 1 are surrounded to form a storage space for accommodating a drawer unit 5, and the drawer unit 5 is slidably placed on the shelf 3. The drawer unit 5 comprises a door panel 52, a left side panel 53, a right side panel 54 and a back panel 55, and the door panel 52, the left side panel 53, the right side panel 54, the back panel 55 and the bottom panel are surrounded to form a drawer structure, and the electronic components of the switch cabinet can be installed in the drawer structure. The width of the door panel 52 of the drawer unit 5 is slightly larger than the distance between the left panel 53 and the right panel 54. When the drawer unit 5 slides to be completely placed on the shelf, that is, when the drawer unit 5 slides to completely enter the accommodating space, at least one of the two ends of the door panel 52 abuts against the columns 1 on both sides to form a limit.

[0023] A roller 51 is provided on each side of the lower rear portion of the drawer unit 5. In this embodiment, the rollers 51 are connected to the lower rear portions of the left side plate 53 and the right side plate 54, respectively. A connecting piece 31 is provided at the sliding position of the shelf 3 corresponding to the roller 51. The extending direction of the connecting piece 31 is the same as the sliding direction of the roller 51. In this embodiment, the connecting piece 31 is an integrally formed sheet metal part, and the connecting piece 31 is fixed to the shelf 3 by bolts. A recess 32 is provided at the rear end of the connecting piece 31. The recess 32 is adapted to accommodate a part of the roller 51. When the drawer unit 5 slides to be completely placed on the shelf 3, the roller 51 falls into the recess 32. In this embodiment, a through groove 34 is provided at the position of the shelf 3 corresponding to the recess 32. When the connecting piece 31 is installed on the shelf 3, the recess 32 is recessed into the through groove 34.

[0024] In this embodiment, the rear end of the recessed portion 32 is connected to a buffer portion 33 extending obliquely backwards, and the angle between the buffer portion and the horizontal plane is 30° to 60°.

[0025] In actual operation, the drawer structure of the low-voltage switch cabinet can be placed in the accommodation space formed by the shelf 3 and the column 1 to accommodate the drawer unit 5. Push the drawer unit 5, the roller 51 can slide on the connecting piece 31, continue to push the drawer unit 5, and the roller 51 slides until a part of the roller 51 falls into the recess 32. At this time, the drawer unit is stably placed on the shelf 3 and stops sliding. If the operator has a large operating force, the roller 51 may continue to move after falling into the recess 32. At this time, the roller 51 may contact the buffer 33. Under the action of the buffer 33, the drawer unit 5 can be prevented from sliding out of the connecting piece 31 and has a certain buffering effect, preventing the drawer unit 5 from hitting other structural parts of the device, reducing the generation of noise and avoiding collision damage. When the drawer unit 5 needs to be removed, a certain force needs to be applied to pull the drawer unit 5 outward. At this time, the roller 51 moves out of the recess 32, and the drawer unit 5 can be pulled out smoothly. The device has a simple structure, low cost, and convenient operation, and is suitable for the current low-voltage switch cabinet structure.
