Disclosure of Invention

The utility model aims at providing a transmission of spring bolt that trouble is few, reliable operation to prior art's defect.

Realize the utility model discloses the technical scheme that the purpose was adopted as follows:

the utility model provides a drive mechanism of spring bolt, including fixed driving gear and the driven gear who drives the spring bolt motion of establishing on motor element's power output shaft, the driving gear through the swing arm gear assembly with driven gear is connected.

The swing arm gear assembly comprises a swing arm and a swing arm gear, wherein one end of the swing arm gear is movably arranged on the power output shaft and can rotate, and the swing arm gear is arranged at the other end of the swing arm and is simultaneously meshed with the driving gear and the driven gear.

Further, the swing arm gear assembly is connected with the driven gear through a bridge gear assembly.

The intermediate gear assembly comprises a first intermediate gear and a second intermediate gear which are fixedly connected coaxially, and the first intermediate gear and the second intermediate gear are respectively meshed with a swing arm gear and a driven gear in the swing arm gear assembly.

Advantageous effects

1. The utility model discloses be connected through the swing arm gear assembly between the driven gear of motor element and drive spring bolt motion, accessible swing arm gear assembly output great effort drive driven gear rotates when motor element starts, can overcome the resistance of locking or when unblanking, is difficult to appear the dead phenomenon of card, and the trouble is few, reliable operation, can prolong the life of lock.

2. Because the swing arm gear assembly is movably fixed on the power output shaft of the motor assembly, when the emergency unlocking is carried out by using a key, even if the motor assembly is blocked and cannot work, the rotation of the driven gear cannot be hindered by the swing arm gear assembly, and the emergency unlocking is ensured not to be failed.

The technical scheme of the utility model is further explained in the following with the attached drawings.

Detailed Description

Example 1

Referring to fig. 1 and 2, the driving mechanism of the latch bolt provided by the present invention comprises a driving gear 201 fixedly arranged on a power output shaft 202 of a motor assembly 2 and a driven gear 7 for driving a latch bolt 6 to move, wherein the driving gear 201 is connected with the driven gear 7 through a swing arm gear assembly 3; the swing arm gear assembly 3 comprises a swing arm 301 and a swing arm gear 302, one end of the swing arm 301 is movably mounted on the power output shaft 202, and the other end of the swing arm 301 is movably provided with the swing arm gear 302 which is simultaneously meshed with the driving gear 201 and the driven gear 7. The motor assembly 2, the lock tongue 6 and the driven gear 7 are all arranged on the lock body 1, and a shifting block 701 is arranged on the driven gear 7 and matched with 2

bayonets

601 and 602 on the lock tongue 6; the driven gear 7 can also be driven by a mechanical lock 5, the mechanical lock 5 comprises a lock tube 501 and a lock cylinder 502 arranged in the lock tube 501, the mechanical lock 5 passes through the mounting plate 101 of the lock body 1 through the tail part 5011 of the lock tube 501 and is fixed by a screw 4 on the lock body 1, and the lock cylinder 502 is axially connected with the driven gear 7; the motor assembly 2 comprises a motor and a speed reducing mechanism, and a driving gear 201 is fixedly arranged on a power output shaft 202 of the speed reducing mechanism.

The working principle is as follows:

intelligent locking and unlocking

1. Locking intelligently: as shown in fig. 1, the motor assembly 2 drives the swing arm gear 302 on the swing arm gear assembly 3 clockwise through the power output shaft 202 and the driving gear 201 counterclockwise to rotate, and drives the swing arm 301 counterclockwise to swing, so that the swing arm gear 302 is engaged with the driven gear 7 to drive the driven gear 7 counterclockwise, and the driven gear 7 is matched with the bayonet 601 on the lock tongue 6 through the shifting block 701 on the driven gear, so as to drive the lock tongue 6 to extend out of the lock body 1, thereby completing locking.

2. Unlocking intelligently: as shown in fig. 3, the motor assembly 2 drives the swing arm gear 302 on the swing arm gear assembly 3 clockwise through the power output shaft 202 and the driving gear 201 to rotate counterclockwise, and drives the swing arm 301 to swing clockwise, so that the swing arm gear 302 is engaged with the driven gear 7 to drive the driven gear 7 to rotate clockwise, and the driven gear 7 is matched with the bayonet 602 on the lock tongue 6 through the shifting block 701 on the driven gear 7, so as to drive the lock tongue 6 to retract into the lock body 1, thereby completing unlocking.

Mechanical unlocking and locking

When the intelligent control is unlocked and is invalid, the lock needs to be unlocked and locked in an emergency mode through a key. After the key is inserted into the lock core 502, the lock core 502 is rotated to directly drive the driven gear 7, and the driven gear 7 drives the bolt 6 to move, so that locking and unlocking are completed.
