Abstract

The present application discloses a multifunctional manual interlocking device for a drawer-type electric cabinet, comprising: a base; a worm screw mounted on the base for rotation; Shake hole; large gear, rotatably installed on the base, the large gear has a tooth and a limiting part, the tooth is meshed with the pinion, and the outer wall of the limiting part has a number of limiting slots; the shrapnel, installed on the base, has a The elastic part against which the outer side wall of the position part is used for cooperating with the limiting groove and making a prompt sound. When this application is used, the hand crank is inserted into the hand crank hole, and the pinion and the worm can be driven to rotate by turning the hand crank. When the pinion rotates, the large gear can be driven to rotate, that is, the position of the limiting groove can be continuously changed. When the position slot is facing the elastic part of the shrapnel, the elastic part can be inserted into the limit slot to make a sound, indicating that the base is at a certain position at this time, and the hand-crank mechanism of the present application has a good operating experience.

Description

technical field [0001] The invention relates to the field of electrical cabinets, in particular to a multifunctional manual interlocking device for a drawer-type electrical cabinet. Background technique [0002] Withdrawable low-voltage power distribution cabinet (drawer-type electrical cabinet) has the advantages of saving space, reliable operation, convenient installation and maintenance, strong breaking capacity, and many outlet circuits. It is widely used in power plants, substations, factories and mines, and high-rise buildings. In the power distribution system of the application. The main function of the power distribution cabinet is to convert, distribute and control power for power distribution, motor control and lighting power distribution equipment. [0003] The hand-operated interlocking device of the drawer-type electrical cabinet drives the drawer to move through the hand-operated handle, so as to switch positions (such as withdrawing, isolating, testing or con...
