Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the present invention is described in detail:
As shown in Figure 1, built-in lock for anti-theft of the present invention comprises fixed head 1, portable plate 4, drive unit, trigger switch K1, warning circuit, drive circuit, release circuit and the first stroke K switch 3, second travel switch K4.Fixed head 1 is fixed on security door indoor surface, and the upper and lower both sides of fixed head are provided with chute.Can move in chute in the chute that portable plate 4 is placed in fixed head both sides, portable plate one end is provided with dead bolt 3 for locking a door and opening the door, and is provided with square and wears dead slot in the middle part of portable plate, and this is worn inside the upper and lower both sides of dead slot and is provided with tooth.Drive unit comprises motor 5 and gear 6, gear is fixed on described motor shaft one end, gear is placed in square in the middle part of portable plate and wears in dead slot and wear inside the upper and lower both sides of dead slot with this and engage to drive portable plate to move in the chute on fixed head both sides, and motor is fixed on fixed head and is electrically connected to realize rotating with described drive circuit.Trigger switch K1 to be placed in security door bright lock outer panels and to be electrically connected to provide triggering signal to warning circuit with described warning circuit.Warning circuit is electrically connected with described drive circuit.Release circuit is electrically connected with described drive circuit.First stroke K switch 3, second travel switch K4 is individually fixed in fixed head front and back ends, and is electrically connected to limit portable plate position movable in fixed head chute respectively with drive circuit.
Trigger switch K1 is prior art, Chang Kai, is closed when the bright lock outer panels of security door prizes.
Warning circuit can be prior art.The invention provides a kind of warning circuit, as shown in Figure 2, comprise NE555 and separate alert K switch 2, electric horn and relay J 8 without steady time-base integrated circuit, relay J 1, two pole.Relay J 1 coil is connected to 4,3 terminals of NE555 without steady time-base integrated circuit.The fixing feet that alert K switch 2 is separated in two poles is connected to 6 terminals of NE555 without steady time-base integrated circuit, one end of K switch 2 is normally closed is connected to 3 terminals of NE555 without steady time-base integrated circuit after connecting with trigger switch K1, and the other end of K switch 2 is often opened and is connected to 2 terminals of NE555 without steady time-base integrated circuit.After connecting with the normally open contact J1-1 of relay J 1,1,4 terminals of NE555 without steady time-base integrated circuit are connected to after the coils from parallel connection of coils of electric horn and relay J 8, again.Just triggered trigger switch K1 when the outer side chain outer panels of security door prizes, provide triggering signal to warning circuit, relay J 1 action, normally open contact J1-1 closes, and electric horn carries out audible alarm.Two poles are separated alert K switch 2 and are placed in inside security door, and for manually sounding all clear, all clear when one end that K2 connects with trigger switch K1 disconnects, relay J 1 power-off, makes warning circuit restore.
Release circuit can be prior art.The invention provides a kind of release circuit, as shown in Figure 3, comprise relay J 7 and unlocking signal input unit.Unlocking signal input unit is remote signal input unit, is prior art, thinks that the control circuit of relay J 7 provides unlocking signal.Pin remote controller motionless, after input unlocking signal, relay J 7 action, the normally open contact J7-1 being connected to drive circuit closes, motor reversal is unlocked, after unblock, removes and report to the police, relay J 1 power-off, makes warning circuit restore, and unclamps remote controller and release circuit is also restored.
Drive circuit can be prior art.The invention provides a kind of drive circuit, as shown in Figure 4, comprise relay J 2, relay J 3, relay J 4, relay J 5, relay J 6.The coil of relay J 2 is connected to control power supply after connecting with the normally open contact J7-1 of release circuit relay J 7.Control power supply is connected to the normally open contact J8-1 of warning circuit relay J 8, the normally closed interlock J2-2 of relay J 2 after connecting after the coils from parallel connection of coils of relay J 3, relay J 4, again.After the coils from parallel connection of coils of relay J 5, relay J 6, connect with the normally open contact J2-1 of relay J 2 again after be connected to control power supply.One end of normally open contact J4-1, J6-1 of relay J 4, relay J 6 is connected to a pole of motor power jointly, one end of the other end of normally open contact J4-1 and the normally open contact J5-1 of relay J 5 is connected to one end of coil of stator of motor jointly, one end of the other end of normally open contact J6-1 and the normally open contact J3-1 of relay J 3 is connected to the other end of coil of stator of motor jointly, and the other end of normally open contact J3-1, normally open contact J5-1 is connected to another pole of motor power jointly after connecting with the normally closed interlock of the first stroke K switch 3, second travel switch K4 respectively.After warning circuit triggers, the normally open contact J1-1 of warning circuit relay J 1 closes, relay J 3, relay J 4 action, and its normally open contact closes, and motor rotates forward, and built-in lock is locked.When needing to unlock, input unlocking signal, relay J 7 action of release circuit, the normally open contact J7-1 being connected to drive circuit closes, and relay J 2 action, makes relay J 5, relay J 6 action, motor reversal is unlocked.
For the ease of installing and hiding this built-in lock, and beautify, can also fixed bin be set.Fixed head, portable plate, drive unit, the first stroke K switch 3, second travel switch K4 are fixed in this fixed bin, and the dead bolt of portable plate can stretch out this fixed bin, and this fixed bin is fixed on security door indoor surface.
In order to make portable plate mobile more smooth in the chute of fixed head both sides, the both sides that portable plate is placed in the chute of fixed head both sides can be flexibly connected with fixed head by pulley.
