Abstract

The utility model discloses a clutch drive mechanism of a lock, comprising an electric motor 1, a worm 2, an A shaft 3, a spring 4, a swing arm 5, a clutch pin 6 and a B shaft 7. The worm 2 is installed on the electric motor; the spring is installed on the A shaft 3 and can rotate around the A shaft 3; both ends of the spring 4 are respectively connected with the worm 2 and the swing arm 5; the swing arm 5 is sleeved on the B shaft 7 and can rotate around the B shaft 7 and abuts against the clutch pin 6. The clutch drive mechanism of the lock controls a drive mechanism through the rotation of the electric motor, and realizes the drive function.

Description

The clutch drive of lock

Technical field

The utility model relates to a kind of component of lock, particularly a kind of clutch drive of lock.

Background technology

At present, the clutch drive of the employed lock of people is varied.

Summary of the invention

The purpose of this utility model provides a kind of clutch drive of novel lock, by the rotation of motor, drives worm screw, spring, swing arm campaign, drives the on-of pin action, realizes the driving function, and simple in structure, easy to use, cost of production is low.

In order to achieve the above object, the technical solution of the utility model is as follows:

A kind of clutch drive of lock comprises motor 1, worm screw 2, A axle 3, spring 4, swing arm 5, on-of pin 6, B axle 7; Worm screw 2 is contained on the motor 1, and spring 4 is contained on the A axle 3 and can rotates around A axle 3, and the two ends of spring 4 link with worm screw 2 and swing arm 5 respectively, and swing arm 5 is set on the B axle 7, can rotate around B axle 7, and offset with on-of pin 6.

Owing to adopted said structure, can control driving mechanism by rotatablely moving of motor, realize driving function.

Description of drawings

Fig. 1 is the utility model structural representation;

Fig. 2 is on-of pin 6 bulged-in states;

Fig. 3 is the state that on-of pin 6 ejects.

The specific embodiment

Below in conjunction with drawings and Examples the utility model is described in further detail:

As shown in Figure 2, when motor 1 drove worm screw 2 forward rotation, driving spring 4 rotated around A axle 3 clockwise directions, and spring 4 is stirred swing arm 5 and counterclockwise rotated around B axle 7, and is pressed into on-of pin 6, makes clutch be in engagement state.

As shown in Figure 3, when motor 1 drove worm screw 2 backward rotation, driving spring 4 counterclockwise rotated around A axle 3, and spring 4 is stirred swing arm 5 and rotated around B axle 7 clockwise directions, and on-of pin 6 is ejected, and clutch is in released state.

Claims
