[0002] The low-voltage switch cabinet is suitable for power plants, petroleum, chemical industry, metallurgy, textile, high-rise building and other industries, and is used for power transmission, power distribution and power conversion. The low-voltage draw-out type switch cabinet is composed of a fixed cabinet body and a movable device part equipped with main electrical components such as switches. When the movable part is moved, it should be light and easy to move. After moving in, the positioning should be reliable. The drawers of the same type and specification can be reliably interchanged. The processing method of the cabinet body part in the draw-out type is basically similar to that in the fixed type. However, due to the requirement of interchangeability, the precision of the cabinet body must be improved, and the related parts of the structure must have sufficient adjustment amount. As for the movable device part, it should be able to move and reliably hold the main components, so it should have high mechanical strength and high precision.

[0003] After searching, a low-voltage draw-out type switch cabinet (authorized publication number CN211239065U) is disclosed in Chinese patent, which comprises a cabinet body, a slide rail is fixedly connected to the inner side wall of the cabinet body, one end of the pulley is fixedly connected to the side wall of the drawer, a wire slot is fixedly connected to the inner wall of the cabinet body, a wiring terminal is fixedly connected to the upper end of the wiring seat, a ventilation and heat dissipation device is arranged below the ventilation plate, a damping device is arranged below the cabinet body. Although this patent technology can prevent the wires from being tangled by the arrangement of the wire slot, it achieves the purpose of making the wires inside the cabinet easy to maintain, and through the cooperation of the clamping device, it achieves the purpose of preventing the wiring from loosening when the drawer is pulled out. Through the arrangement of the ventilation and heat dissipation device and the thermometer, it achieves the purpose of preventing the damage of the electrical components caused by the humidity and high temperature inside the cabinet. Through the arrangement of the damping device, the shock resistance of the cabinet is improved.

[0004] However, various control electrical components of the switch cabinet are installed in the drawer, which needs to be pulled out during daily installation and removal and daily inspection and maintenance. Since many electrical components are installed in the drawer and have a certain weight, the drawer will be completely pulled out and fall to the ground and be damaged if it is not careful when pulling out the drawer. When the electrical components in the drawer are maintained, some drawers will be pulled out. At this time, if the weight of the pulled-out part is greater than the weight of the cabinet, the pulley below will be damaged due to long-term extrusion, which will inevitably affect the subsequent use.
