Abstract

The utility model relates to a lock body controlled to be started and closed by power, which is mainly used for the door with high anti-theft property requirement. The utility model comprises a lock body shell, and the inside of the shell is provided with a lock tongue, a lock tongue advancing power mechanism, a lock tongue retreating stopping mechanism and a control circuit terminal block. Wherein, the lock tongue is formed by the lock tongue body(4), a sliding groove(5) positioned on the lock tongue body, a positioning pin(6) positioned in the sliding groove, and a back tension spring(7). The lock tongue advancing mechanism comprises a motor(8) with gear(9), and the gear is connected with the lock tongue body(4) through the rack(10). The lock tongue retreating stopping mechanism is formed by the electromagnet(1), an iron core retreating stopping pin(2) and a pushing retreating stopping spring(3). The electromagnet, the lock tongue body positioning pin, the motor with gear and the control circuit terminal block are respectively positioned on the internal side wall of the lock body shell. The lock body realizes electric starting or closing and can be installed in invisible manner, thereby effectively preventing the arbitrary starting in and outside the door of the lock body.

Description

The lock body of automatically controlled open and close

Technical field

The utility model relates to a kind of electronic lock lock body, especially relates to a kind of lock body by automatically controlled open and close, belongs to the Remote control electronic lock technical field.

Background technology

At present, the lock body of known electronic lock has by automatically controlledly closing, manually open or manually close, automatically controlledly opening two big classes, so two actions of closing and open of this lock body can only be unidirectional automatically controlled, then can not be applicable to lock body stealthy high security door of theftproof of installing in door; Lock body subjects to be subjected to Men Nei or violence damage outdoors, also carries out technical unlocking simultaneously easily.

Summary of the invention

For realize that lock body opens and close two-way automatically controlled and be convenient to stealthy purpose of installing in door; The utility model provides a kind of lock body of automatically controlled open and close, and it is unblanked by magnet control by the Electric Machine Control locking.

The technical scheme that the utility model adopted is: be made up of dead bolt, dead bolt onward impulse mechanism, dead bolt stopping mechanism and control circuit terminal plate device in lock body shell, the shell.Wherein dead bolt is by having the dead bolt body, being provided with on the dead bolt body and alignment pin is set in chute, the chute, also is provided with returning pull-spring is constituted on the dead bolt body, and extension spring one end is fixed on the dead bolt body, and the other end connects the lock body shell; Dead bolt onward impulse mechanism is that the end by motor, motor shaft is provided with gear, this gear and connects as one by tooth bar and dead bolt body and constitute, and its middle rack and dead bolt body one side are cast into one, and wheel and rack directly meshes; The dead bolt stopping mechanism is by electromagnet, iron core retaining pin and advances iron core retaining pin spring to constitute; Electromagnet, alignment pin, the motor that has gear and control circuit terminal plate are separately fixed on the inside wall of lock body shell.

The utility model compared with prior art has the following advantages: the electronic lock lock body has been realized opening with closed two-way automatically controlled, so in door, can stealthyly install, prevent effectively that then lock body from suffering Men Nei or violence damage outdoors and mischief, simultaneously also prevent technical unlocking, it is applicable to the class of high theftproof requirement.

Description of drawings

Following accompanying drawing has provided embodiment of the present utility model:

Fig. 1 is an internal construction schematic diagram of the present utility model.

Below in conjunction with accompanying drawing overall structure of the present utility model and operating principle are described further.

The specific embodiment

As shown in Figure 1: the lock body of this automatically controlled open and close is made up of dead bolt, dead bolt onward impulse mechanism, dead bolt stopping mechanism and control circuit terminal plate 11 device in lock body shell 13, the shell.Wherein dead bolt is by device alignment pin 6 being set on dead bolt body 4, the dead bolt body in chute 5, the chute, also being provided with returning pull-spring 7 constituting on the dead bolt body, wherein extension spring one end is fixed on the dead bolt body, the other end connects the lock body shell, and dead bolt can move along horizontal bidirectional; Dead bolt onward impulse mechanism is connected as one by tooth bar 10 and dead bolt body 4 by the end fitting gear 9 of motor 8, motor shaft, this gear to constitute, and tooth bar and dead bolt body one side cast in one, and wheel and rack directly meshes; The dead bolt stopping mechanism is by electromagnet 1, iron core retaining pin 2 and advances iron core retaining pin spring 3 to constitute; Described electromagnet 1, dead bolt body alignment pin 6, the motor 8 that has gear and control circuit terminal plate 11 are separately fixed on the inside wall of lock body shell.The lead-in wire of motor and electromagnet is pegged graft with terminal plate respectively, and outwards draws control line by three core sockets 12.

Operating principle: during electrical power, when the pulling force that gear 9 overcomes extension spring 7 by tooth bar 10 drove dead bolt body 4 and stretches out lock body shell 13 and put in place, iron core retaining pin 2 is outwards motion and with dead bolt body 4 retainings under the effect of spring 3, makes the locking lock.When electromagnet was switched on, the iron core retaining pin overcame the spring force withdrawal under the electromagnetic force effect, remove retaining, at this moment in the dead bolt body withdrawal lock body shell, will lock unlatching under the effect of extension spring power.
