Description

Technical Field

[0001] The utility model relates to the technical field of power distribution cabinets, in particular to a drawer unit of a power distribution cabinet. Background Art

[0002] The distribution cabinet is divided into power distribution cabinet, lighting distribution cabinet and metering cabinet. It is the final equipment of the distribution system. The distribution cabinet is a general term for the motor control center. The distribution cabinet is used in occasions where the load is relatively dispersed and there are fewer circuits.

[0003] During the use of the existing distribution cabinet, various electrical equipment needs to be placed on the drawer unit inside the distribution cabinet to facilitate its use. However, since the sizes of electrical equipment are different, this leads to the inability of the single-structured and fixed drawer unit to adapt to electrical equipment of different sizes, which has limitations. In order to address the above problems and defects, a distribution cabinet drawer unit and a distribution cabinet are urgently needed. Utility Model Content

[0004] The technical problem to be solved by the utility model is to provide a distribution cabinet drawer unit and a distribution cabinet to solve the problem that during the use of the existing distribution cabinet, various power equipment need to be placed on the drawer unit in the distribution cabinet to facilitate its use. However, since the sizes of power equipment are different, this leads to the problem that the single-structured and fixed drawer unit cannot adapt to power equipment of different sizes.

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

[0006] A drawer unit of a power distribution cabinet comprises: a positioning frame, the positioning frame is provided with a drawer body and a limit assembly, the inner wall of the positioning frame is provided with a limit groove, and the bottom of the inner wall of the limit groove is provided with a clamping groove; the limit assembly comprises a connecting rod installed on the outer wall of the drawer body, the bottom of the connecting rod away from the drawer body is provided with a circular groove, the top of the circular groove is fixedly equipped with a spring, the bottom end of the spring is fixedly equipped with a connecting block, the bottom of the connecting block is fixedly equipped with a clamping block, the outer wall of the connecting rod is provided with a through groove, the inner wall of the through groove is rotatably connected with a rotating shaft, the top of the connecting block is fixedly equipped with a connecting rope, the end of the connecting rope away from the connecting block is fixedly connected to the outer wall of the rotating shaft, and the end of the rotating shaft away from the connecting rope is fixedly equipped with a knob.

[0007] The inner wall of the positioning frame is provided with a slide groove, the inner wall of the slide groove is provided with a movable groove, the inner wall of the slide groove is slidably connected to the drawer body, the drawer body includes a transverse plate, both sides of the transverse plate are rotatably connected with rollers, and the outer wall of the roller is rollingly connected to the movable groove.

[0008] The slot openings of the sliding slot and the moving slot are both provided with guide slots, and the cross-sectional shape of the guide slots is an isosceles trapezoid.

[0009] A groove is provided on one side of the transverse plate away from the clamping block, and a handle is fixedly mounted on the inner wall of the groove.

[0010] A placement groove is provided on the top of the transverse plate, and a rubber pad is provided on the inner wall of the placement groove.

[0011] The cross-sectional shape of the clamping block is a right-angle trapezoid, and the hypotenuse of the clamping block is located at a side away from the knob.

[0012] A power distribution cabinet comprises a cabinet body and a plurality of the power distribution cabinet drawer units.

[0013] Compared with the prior art, the utility model has at least the following beneficial effects:

[0014] 1. In the above scheme, different drawer bodies are inserted into corresponding slide grooves and movable grooves according to different sizes of power equipment, so that the distance between the two drawer bodies can meet the size of the power equipment, which is conducive to improving the adaptability of the device and ensuring the normal use of the device.

[0015] 2. In the above scheme, when the drawer body is inserted into the sliding groove and the moving groove, the connecting rod is also inserted into the limiting groove at the same time. When the block at the bottom of the connecting rod is squeezed, the block moves to the top of the circular groove. When the connecting rod is inserted into the limiting groove, the block is no longer squeezed, and the connecting block and the block are pushed downward by the spring. At this time, the block and the slot are engaged, so that the drawer body is guaranteed not to fall when the drawer body is pulled out. When the drawer body needs to be changed, it is only necessary to turn the knob to drive the rotating shaft to rotate, and then the connecting rope is wrapped around the rotating shaft. At this time, the connecting block and the block are pulled to move to the top of the circular groove, and the drawer body and the limiting assembly can be removed, which is beneficial for limiting the drawer body and facilitating its change of position.
