Description

Double post electric lock

technical field

The utility model relates to a double-column electric lock.

Background technique

The current popular electric locks on the market adopt the working mode of electromagnetic attraction and spring return, which has the disadvantages of complex structure and loud working noise.

Contents of the invention

The purpose of the utility model is to provide a double column electric lock with small volume, simple structure, no working noise and convenient electric control.

The purpose of this utility model is achieved in this way: the outside is composed of a box body and a box cover, and it is characterized in that: the box body is equipped with a reducer that cooperates with the motor, a turntable with two dial pins, two lock cylinders, Two collets; the turntable has a central hole that matches the output shaft of the reducer, the collet has a plane that fits the turntable, and a U-shaped groove that is movably matched with the toggle pin is provided on the plane, and the lock column is fixed on the clip On the head, the sleeve is fixed on the box, and the sleeve is provided with a hole for dynamic cooperation with the lock column, and the motor and the reducer are fixed on the box by fasteners.

The utility model has the following advantages: small volume, low cost, no working noise, and convenient control.

Below in conjunction with accompanying drawing and specific embodiment, the utility model is described in further detail.

Detailed ways

As shown in Figure 1-2, the double-column electric lock is composed of a box body 12 and a box cover 13 on the outside. It is characterized in that: the box body 12 is equipped with a reducer 2 that cooperates with the motor 1, and has two dial pins. The turntable 3 of 5, two lock cylinders 6, and two chucks 16; the turntable 3 has a central hole 15 that matches the output shaft 4 of the reducer 2, and the chuck 16 has a plane 7 that fits the turntable 3, The plane 7 is provided with a U-shaped groove 8 that is movably matched with the dial pin 5, the lock cylinder 6 is fixed on the chuck 16, the sleeve 9 is fixed on the box body 12, and there is a U-shaped groove 8 on the sleeve 9 that is movably matched with the lock cylinder 6. Hole 10, motor 1 and speed reducer 2 are fixed on the casing 12 by fastener 11, and the terminal 14 of motor is externally connected to power supply, and case cover 13 is fixed on the casing 12, constitutes a complete lock like this. Its working principle is as follows: After the motor 1 is powered on, it rotates at a high speed, and after being decelerated by the gear reducer 2, the speed transmitted to the output shaft is 12-15 rpm. The output shaft drives the turntable 3 to rotate and transmit torque, and the turntable 3 is output Driven by the shaft, it can rotate clockwise or counterclockwise. At the same time, the two pulling pins 5 on the turntable slide in the "U"-shaped grooves 8 of the two chucks 16, pushing the chucks 16 to move, thereby realizing the two locking cylinders 6 extended or retracted. Since the side of chuck 16 fits with turntable 3, after lock cylinder 6 cooperates with chuck 16, turntable 3 and sleeve 9, according to the principle of six-point positioning, lock cylinder can only move in degrees of freedom along the axis of lock cylinder.
