Anti-toppling drawer type switch cabinet

Abstract

The invention discloses an anti-toppling drawer type switch cabinet. According to the technical scheme, the anti-toppling drawer type switch cabinet comprises a cabinet body, a plurality of drawers are connected to the cabinet body in a sliding mode, an anti-toppling device is arranged on the cabinet body, a device cavity is formed in the bottom of the cabinet body, the anti-toppling device and the drawers are arranged in a linkage mode, and the anti-toppling device comprises a driving plate arranged in the device cavity; the bottom of the driving plate is provided with a plurality of reset springs for connecting the device cavity; connecting rods are hinged to the two ends, facing the side face of the drawer, of the driving plate, horizontally-moving push rods are hinged to the connecting rods, one ends of the push rods are hinged to the connecting rods, supporting legs are hinged to the other ends of the push rods, and the pair of supporting legs are hinged to the cabinet body; an electromagnet located above the driving plate is further arranged in the device cavity, and a magnetic block matched with the electromagnet is arranged on the top face of the driving plate. Through the arrangement, after the drawer is pulled out, the driving plate can push the push rod to unfold the supporting legs, so that an auxiliary supporting effect on the cabinet body is achieved, and the cabinet body is prevented from toppling due to the change of the gravity center.

Description

technical field [0001] The invention relates to the technical field of switch cabinets, in particular to an anti-dumping drawer type switch cabinet. Background technique [0002] Low-voltage switchgear is suitable for power plants, petroleum, chemical industry, metallurgy, textiles, high-rise buildings and other industries, as power transmission, power distribution and power conversion. Low-voltage switchgear can be divided into fixed type and withdrawable type from the structure. The withdrawable type is composed of a fixed cabinet and movable drawers equipped with main electrical components such as switches, which can facilitate the disassembly, movement and repair of electrical components. [0003] Because there are many electrical components installed in the existing drawer, it will be relatively heavy, and it will take a lot of strength to pull out the drawer. Therefore, when the drawer is pulled out, the drawer will often fall to the ground due to the drawer’s withdraw...

AI Technical Summary

Problems solved by technology

[0003] Because there are many electrical components installed in the existing drawer, it will be relatively heavy, and it will take a lot of strength to pull out the drawer. Therefore, when the drawer is pulled out, the drawer will often fall to the ground due to the drawer’s withdrawal speed is too fast. and during maintenance, when the drawer is pulled out, the center of gravity of the cabinet will change, which will cause the cabinet to tilt forward and roll over, thus threatening the safety of the staff
