Abstract

The utility model discloses a transmission mechanism of an electric lock clutch, including a guide sleeve 1, a transmission pin 2, a shaft 3, a torsion spring 4, a worm bar 5, a diving gear 6, a motor 7, a driven gear 8 and a limit baffle 9; the driving gear 6 is arranged on the shaft of the motor 7, the driven gear 8 is connected into a whole by the shaft of the worm bar 5, the driving gear 6 and the driven gear 8 are mutually meshed; the torsion spring 4 is sleeved on the shaft 3, the lower end of the transmission pin 2 is provided with a through hole 10, one side of the torsion spring 4 is meshed with the worm bar 5, another side of the torsion spring 4 inserts the hole 10; the transmission pin 2 is positioned in the guide sleeve 1 which can move in line corresponding to the guide sleeve 1, the limit baffle 9 is positioned below the transmission pin 2. The utility model controls the transmission mechanism by the rotation movement of the motor to realize the transmission function.

Description

The driving mechanism of electronic lock clutch

Technical field

The utility model relates to a kind of component of lock, particularly a kind of driving mechanism of electronic lock clutch.

Background technology

At present, the driving mechanism of the employed electronic lock clutch of people is varied.

Summary of the invention

The purpose of this utility model provides a kind of driving mechanism of novel electronic lock clutch, by rotatablely moving of motor, is transformed into the rectilinear motion of drive pin, realizes 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 driving mechanism of electronic lock clutch comprises guide pin bushing 1, drive pin 2, axle 3, torsion spring 4, worm screw 5, driving gear 6, motor 7, driven gear 8 and postive stop baffle 9; Driving gear 6 is contained on the axle of motor 7, and driven gear 8 fuses by the axle of worm screw 5, and driving gear 6 and driven gear 8 are meshing with each other; Torsion spring 4 is enclosed within on the axle 3, and drive pin 2 lower ends are provided with a through hole 10, and an end of torsion spring 4 and worm screw 5 meshes, and the other end is then in the patchhole 10; Drive pin 2 is arranged in guide pin bushing 1, guide pin bushing 1 rectilinear motion relatively, and postive stop baffle 9 is positioned at the below of drive pin 2.

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 in the state of top position for drive pin;

Fig. 3 is in the state of lower position for drive pin.

The specific embodiment

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

When motor 7 rotates by direction shown in Figure 2, be rotated in the forward by driving gear 6 drive driven gears 8 and worm screw 5, the lower end that worm screw 5 promotes torsion spring 4 is moved to the left, and torsion spring 4 rotates around axle 3 clockwise directions, and the upper end of torsion spring 4 is stirred drive pin 2 and moved upward, move to after top dead center, because the position-limiting action of guide pin bushing 1 can not move upward again, worm screw 5 continuation rotations this moment, cause torsion spring 4 to produce distortion, thereby keep in touch with worm screw 5 all the time.

When motor 7 rotates by direction shown in Figure 3, drive driven gear 8 and worm screw 5 reverse rotations by driving gear 6, the lower end that worm screw 5 promotes torsion spring 4 moves right, and torsion spring 4 counterclockwise rotates around axle 3, and the upper end of torsion spring 4 is stirred drive pin 2 and moved downward, move to after bottom dead center, because the position-limiting action of postive stop baffle 9 can not move downward again, worm screw 5 continuation rotations this moment, cause torsion spring 4 to produce distortion, thereby keep in touch with worm screw 5 all the time.
