Full-automatic lock

Abstract

The invention discloses a full-automatic lock. The full-automatic lock comprises a lock box, a side panel, a main spring bolt assembly, an inclined bolt assembly and a gear case; a containing space isformed between the lock box and the side panel; the main spring bolt assembly, the inclined bolt assembly and the gear case are installed inside the containing space; through holes allowing a main spring bolt and an inclined bolt to extend out are formed in the side panel; a motor, a tank, a drive gear set and a rack board are arranged on the gear case; and on the one hand, the drive gear sets drives the rack board to move to control the main spring bolt assembly to be locked / unlocked, and on the other hand, a power output wheel rotates to drive a second gear in the inclined bolt assembly, then a second inclined bolt shifting fork is dragged to rotate to lift up or press a first drive piece or a second drive piece, the inclined bolt retracts or extends out of the side panel to be controlled by the motor, and full-automatic control over the lock is achieved. Besides, the motor of the full-automatic block is arranged inside the lock box, the outer space is not occupied, the appearance of the lock is regular, the lock is easy to mount, and the lock can be made smaller and thinner.

Description

technical field [0001] The invention relates to the technology in the field of locks, in particular to a fully automatic lock body. Background technique [0002] The Chinese utility model patent with application number 201620517454.0 discloses a rack and pinion unlocking device for a safety door lock, which directly engages the rack with the main gear, and the rotation of the main gear drives the rack to move. Although this kind of gear can achieve the purpose of the rack moving back and forth, the rack is always in contact with the gear. When the drive starts, the main gear has a large potential energy and the rack is stationary. When the gear drives the rack to move, The process of vigorously toggling is likely to cause slipping and noise. Moreover, the speed of the rack from stationary to moving is uneven, resulting in easy damage to the internal structure, poor contact between parts and components in long-term operation, low stability, and short life. In addition, the ...

Problems solved by technology

Although this kind of gear can achieve the purpose of the rack moving back and forth, the rack is always in contact with the gear. When the drive starts, the main gear has a large potential energy and the rack is stationary. When the gear drives the rack to move, It is easy to cause slippage and noise during the vigorous toggle process

And the speed of the rack from stationary to moving is uneven, resulting in easy damage to the internal structure, poor contact between long-term running parts, low stability, and short life

In addition, the latch bolt assembly of this patented product can only be opened manually through the door handle, and there is no power-driven relationship between the latch latch assembly and the gearbox
