CN2121505U - Electric spring door lock - Google Patents

Abstract

The utility model relates to an electric spring door lock controlled in a long distance, which is suitable for installing on gates of courtyards and house doors of ground floor. The electric spring door lock is that an electric unlocking device is additionally arranged on an ordinary mechanical spring door lock; an electrical motor is underdriven by a worm gear and a spiral spring is tightened; a lock bolt is pulled out to open by a shifting lever which is connected with the spiral spring. When the lock is opened, the circuit of the electrical motor is cut and a braking electromagnet is started to keep the lock bolt in the state of stating. The electric spring door lock can be operated by electricity in a long distance, and besides, the electric spring door lock can be stated mechanically by twisting a turn knob by hand.

Description

Electric spring door lock

The utility model relates to the mechanical billiard door lock that a kind of remote electric operating undoes the lock.The national uses lockset.

The mechanical type pin tumbler lock has the advantage of stable work in work, but its unlatching or close and need artificial direct control can't realize far distance controlled.The gate of the unit of elephant gate, rural area quadrangle and high-rise household's ground floor gates etc., the pin tumbler lock of installation must someone start or stop in person of coming out, and feel inconvenience very much.In order to address the above problem, a series of electromagnetic door locks release one after another.Its operating principle is by energising adhesive electromagnet, directly will open door lock after the dead bolt adhesive.The required electrical power of this lock is big, and gimp is big, meets when having a power failure and just can't work.

The purpose of this utility model is will provide a kind of can open in remote-controlled operation, and the time can make electricity that the common spring door lock the uses pin tumbler lock of operating machine in outage.

The technical solution of the utility model is such: in the pin tumbler lock of being made up of lock housing, dead bolt, bumper bar, spring and lock core etc.; Micromachine is installed, micro machine connects with the inner of a curly hair bar by worm screw and worm gear, the outer end of clockwork spring connects a driving lever, driving lever is linked up with on dead bolt in worm gear one side, the braking electromagnet is installed, when its push rod stretches out and worm gear offset, switch with the switch of braking worm gear micromachine and Breake Electromagnet power-on circuit and controlled by ganged switch, ganged switch then is subjected to the control of dead bolt and bumper bar.

Following the utility model provides embodiment in conjunction with the accompanying drawings.

The accompanying drawing drawing is described as follows:

Fig. 1 is the utility model example structure schematic diagram.

Fig. 2 is the utility model embodiment electrical schematic diagram.

Referring to Fig. 1, form the mechanical billiard door lock by lock housing 11, dead bolt 1, bumper bar 4, spring 5 and lock core etc.In housing, be fixed with 10W and exchange micromachine 9.Driving worm gear 7 by worm screw 10 rotates.A worm-wheel shaft and a curly hair bar 6 are fixedly connected.The outer end of curly hair bar connects a driving lever 2, and driving lever is linked up with on dead bolt 1.Side at worm gear 7 is equipped with Breake Electromagnet 8.When the push rod of electromagnet stretches out and worm gear 7 offset.The switch switching of micromachine and electromagnet power-on circuit is subjected to ganged switch 3 controls simultaneously.Be provided with spring in (as Fig. 2) ganged switch, switch constant close contact and motor circuit are connected, ganged switch is subjected to the control of dead bolt 1 and bumper bar 4.Dead bolt or bumper bar are pressed when leading to ganged switch, and switch switches to another duty.Power supply is 220 volts of civil powers, by switch control power supply.

When needing remote-controlled operation to unblank, connect power switch, motor rotates, and by the worm gear deceleration transmission, tightens clockwork spring.After clockwork spring tightened gradually, the driving lever of connection clockwork spring outer end was pulled out locking bolt with dead bolt and is undone the lock.When dead bolt indentation lock housing, dead bolt is pressed logical ganged switch.Switch is connected the Breake Electromagnet circuit when cutting off motor circuit, the electromagnet push rod stretches out worm gear is propped up, in case dead bolt rebounds after the motor stall.Behind the disconnecting power switch, this lock recovers to do the common spring door lock to be used.Because dead bolt and clockwork spring interlock when the twisted knob of hand, do not influence machinery and unblank.In order to prevent to burn out micro machine because of door lock undoes the lock under the situation of insuring, this bumper bar is ganged switch switch operating state when safety position, disconnects motor circuit.

The remote-controlled operation of this lock is convenient, dependable performance, and electrical power consumed is little, and work noise is little, still can be manually opened under powering-off state.

Claims (1)

1, a kind of pin tumbler lock of establishing by cable, comprise lock housing 11, dead bolt 1, bumper bar 4, spring 5 and lock core, it is characterized in that: be fixed with micromachine 9 in the lock housing, micro machine connects with the inner of curly hair bar 6 by worm screw 10 and worm gear 7, the outer end of clockwork spring 6 connects a driving lever 2, and driving lever is linked up with on dead bolt 1; In worm gear one side Breake Electromagnet 8 is installed, when its push rod stretches out and worm gear 7 offset; The switch switching of micromachine and electromagnet power-on circuit is subjected to ganged switch 3 controls simultaneously, and ganged switch is subjected to the control of dead bolt 1 and bumper bar 4.
