DRIVE MECHANISM drawer units low-voltage devices

摘要

The drive mechanism of the drawer low-voltage devices relates to the field of electrical engineering. The utility model provides a clear fixation of the drawer in the desired positions by blocking the movement of the drawer, and blocking its movement from one desired position to the other when the circuit breaker and the blocking of the circuit breaker in an intermediate position of the drawer, the achieved technical result - increased security maintenance drawer. The drive mechanism includes a drive assembly, drive assembly and locking assembly locks the circuit breaker. Drive assembly 1 comprises a housing with disposed inside the shaft with the worm groove, cooperating with a stop. At the rear end of the drive shaft are made grooves for locking the shaft rotation. Fixing the driving unit 2 comprises a rod with two protrusions mounted on the casing for longitudinal displacement, the lock release button and a return spring. The first rod protrusion into a corresponding groove of the shaft when the drawer reaches the desired position. Lock assembly 3 comprises a circuit breaker mounted on the housing and actuator arm stopper disposed therebetween and sector which interacts with the shaft of the circuit breaker. Sector mounted on the bracket for rotation in a vertical plane when turning the circuit breaker and capable of cooperating with a second stem protrusion. The limiter and the bracket each have a slot for the entry of a second rod protrusion in the intermediate position of the drawer. 4 ZP f ly-5-yl.
