Below in conjunction with embodiment and the time the utility model is described in further detail according to accompanying drawing.

The utility model comprises lock body 1, lock box 6, locking bolt 9, motor 2, battery E and push button panel 17, be processed with tooth bar 11 on the locking bolt 9 in lock body 1, be processed with strip chute 7 in the centre of locking bolt 9, two pulleys 8 are installed in the chute 7, motor 2 is installed on the lock body 1, tooth bar 11 engagements on travelling gear 3 on 2 on the motor and the locking bolt 9 are equipped with the volute spring 4 of a band gear 5 on the next door of motor 2, gear 5 also is meshed with tooth bar 11.Left end at locking bolt 9 is equipped with pulling plug handle 10.8 on pulley reduces resistance and positioning action.

Safeties are by two electromagnet J2, J3, safety fastener 13, insurance knob 12, safety fastener spring 15 and transmission arm 14 are formed, above tooth bar 11, be equipped with on the lock body 1 with the jackshaft is moving fulcrum, rotary safety fastener 13, insurance knob 12 is fixed on the jackshaft of safety fastener 13, rotate insurance knob 12 and can rotate safety fastener 13, safety fastener spring 15 1 ends are fixed on the lock body 1, and the other end is fixed on an end of transmission arm 14, the other end of transmission arm 14 is fixed on the jackshaft of safety fastener 13, at the left arm A of safety fastener 13, right arm B top is separately installed with an electromagnet J3, electromagnet J2.The left arm A of safety fastener 13, it is the plane that pointed, pointed outer face all is processed at the two ends of right arm B, and inner face is the inclined-plane, and pointed outer face can buckle into tooth bar and firmly block, and inner face can slip over above tooth bar.Safety fastener spring 15 and transmission arm 14 play the roof pressure effect.Under the effect of electromagnet J2, J3 or manual safety knob 12, safety fastener 13 can move as seesaw.Bonnet 16 usefulness screws are installed on the lock body 1, cover locking bolt 9, motor 2, volute spring 4, and insurance knob 12 is exposed at outside the bonnet 16.

Push button panel 17 is installed in the outside, gate, in push button panel 17 fronts the protective cover 18 that can twitch is installed, and is equipped with eight and often opens button SB1～SB8 on push button panel 17.

Warning circuit is by triode T1, T2, resistance R 2, R3, and capacitor C 4, loud-speaker Y forms.

Timing circuit is by triode T3, relay J 1 and normal open switch J1-1 thereof, diode D, three polar capacitor C1, C2, C3, and a cutter three throw switch K form.The numerical value difference of capacitor C 1, C2, C3, timing is also inequality.

Motor 2, the normally closed switch J1-2 of relay J 1, thermistor R1, capacitor C 5 are formed motor drive circuit.

One end of going into a press button SB1～SB8 all connects the positive pole of battery E, and the other end connects the contact jaw of eight socket XS1～XS8 respectively, and the earth terminal of eight socket XS1～XS8 all connects the negative pole of battery E.Five plug XP1～XP5 each circuit taking alarm and timing circuits, plug XP6 meets electromagnet J2, plug XP7 meets electromagnet J3, the two ends of plug XP8 successively with thermistor R1, normally closed switch J1-2, motor 2 is cascaded.Eight plug XP1～XP8 can distinguish and insert arbitrarily among eight socket XS1～XS8, reach the purpose of establishment password.

Earlier eight plug XP1～XP8 are inserted respectively arbitrarily among eight socket XS1～XS8 during use, promptly finish password.In the time will unblanking outdoors, correctly press and electromagnet J2 the button that motor 2 links as the people, connect the power supply of electromagnet J2 and motor 2, electromagnet J2 gets electric back and produces suction the right arm B of safety fastener 13 is picked up, and left arm A puts down, and safety fastener spring 15 and transmission arm 14 are to left arm A roof pressure; Motor 2 must turn clockwise by the electric back travelling gear 3 that drives on it, and locking bolt 9 is extracted lock box 6 left out under the effect of travelling gear 3 and tooth bar 11, so just opened lock.In left movement, the gear 5 coaxial with volute spring 4 also clockwise rotates and tightens volute spring 4 under the drive of tooth bar 11, laid in spring energy at locking bolt 9, in order to the usefulness of locking.

When locking as needs, correctly press the button that links with electromagnet J3, connect the power supply of electromagnet J3, electromagnet J3 gets electric back and produces suction the left arm A of safety fastener 13 is picked up, right arm B puts down, and safety fastener spring 15 and transmission arm 14 be to right arm B roof pressure, the constraint of locking bolt 9 when having eliminated left arm A, the volute spring 4 that has tightened just ejects locking bolt 9 by coaxial gear 5 immediately automatically, and locking bolt 9 inserts in the lock boxes 6 to be realized locking.The right arm B of safety fastener 13 just also buckles in the tooth of corresponding tooth bar 11 naturally, insures.

Pulling plug handle 10 and insurance knob 12 are to lock in door and unblank for people, the usefulness of opening insurance and insuring.

By the button that is connected with warning circuit, just make warning circuit connect power supply if any people's mistake, triode T1, the T2 conducting, loudspeaker Y is sent alarm sound.Meanwhile, timing circuit has also been connected power supply, and triode T3 conducting has electric current to flow through in the coil of relay J 1, and constant close contact J1-2 disconnects, and cuts off the power supply of motor 2, and constant open contact J1-1 adhesive is kept the power supply of timing circuit, until reaching timing.After polar circuit C1 or C2 or C3 full charge, the electric current of triode T3 base stage approaches zero, and this moment, triode T3 ended, do not have electric current to flow through in the relay J 1, constant open contact J1-2 disconnects, dump, constant close contact J1-2 closure is recovered motor 2 circuit, regularly finishes.
