Description

Novel dead bolt transmission device

The utility model relates to a kind of lockset.

In the prior art, the transmission device of dead bolt is the executing agency of whole lockset, the flexible unlatching or the closed condition that has determined lockset of dead bolt.The dead bolt of general lockset is to come transmission by the toggle mechanism of device in lock box, this toggle mechanism can be mechanical, also can be electronic, or dynamo-electric combination, all there is application in these mechanisms on common mechanical lock, electronic lock or coded lock, but its structure is relatively complicated, no matter be manual, still be electronic, all need the executing agency of a transition, ability transmission dead bolt, and when emergent, open relatively difficulty.

The purpose of this utility model is: a kind of novel dead bolt transmission device is provided, and this device directly by gear and tooth bar and dead bolt handle engaged transmission, can realize that remote control electric, button are electronic, craft is stirred and multiple mode of operation such as emergency opening with motor.

The technical solution of the utility model is: a kind of novel dead bolt transmission device, comprise the dead bolt that can stretch on lock box, the rear portion of described dead bolt is the dead bolt handle that is positioned at lock box, and the dead bolt handle is provided with tooth bar, motor is installed in the lock box, is fixed with the wheel and rack engagement on the output shaft of motor.

The further technical scheme of the utility model is: a kind of novel dead bolt transmission device, comprise the dead bolt that can on lock box, stretch, the rear portion of described dead bolt is the dead bolt handle that is positioned at lock box, and the dead bolt handle is provided with two slotted holes, is provided with the guiding pin joint screw that is fixed on the lock box in the slotted hole; Described dead bolt handle is provided with tooth bar, and motor is installed in the lock box, is fixed with the wheel and rack engagement on the output shaft of motor.

The more detailed technical scheme of the utility model is: a kind of novel dead bolt transmission device, comprise the dead bolt that can on lock box, stretch, the rear portion of described dead bolt is the dead bolt handle that is positioned at lock box, and the dead bolt handle is provided with two slotted holes, is provided with the guiding pin joint screw that is fixed on the lock box in the slotted hole; Described dead bolt handle is provided with tooth bar, and motor is installed in the lock box, is fixed with the wheel and rack engagement on the output shaft of motor; The side of described dead bolt handle also is provided with emergent tooth bar, is articulated with emergency key on the lock box, and emergency key is provided with emergency gear and the engagement of emergent tooth bar.

The utility model has the advantages that:

1. the utility model is equipped with motor in lock box, is fixed with gear on the output shaft of motor, and forms the rack and pinion engagement on the dead bolt handle, can make the motor direct-drive dead bolt, thereby realizes modes of operation such as remote control electric, button is electronic, craft is stirred.

2. the utility model also is provided with emergent tooth bar on the dead bolt handle, be articulated with emergency key on the lock box, emergency key is provided with emergency gear, under the situation that lockset can't normally be opened, can open by wheel and rack equally with emergency key, and need not destroy lockset.

The utility model will be further described below in conjunction with drawings and Examples:

Fig. 1, Fig. 2 are the front view of the utility model opening and closing state;

Fig. 3 is the rear elevation of the utility model opening;

Fig. 4 is the left view of Fig. 3.

Wherein: 1 lock box; 2 dead bolts; 3 dead bolt handles; 4 tooth bars; 5 motors; 6 gears; 7 slotted holes; 8 pin joint screws; 9 emergent tooth bars; 10 emergency keys; 11 emergency gears.
