The utility model operating principle
The electromagnetic lock of magnet steel Puzzle electronic lock has partly adopted major and minor dead bolt automatic blocking project organization.The concrete structure of electromagnetic lock is seen accompanying drawing 8 and accompanying drawing 9 magnet steel Puzzle electronic lock electromagnetic lock structure figure.The armature 17 of tractive magnet is linked together by master connecting-rod 23 with main dead bolt 24 in accompanying drawing 8 and the accompanying drawing 9.When unblanking, the magnet steel key inserts sensor, and password is input to controller through sensor, after the cryptochannel recognition and verification is correct, makes capacitor C by drive circuit
6Discharge to tractive magnet coil LQ, make iron core 17 and the armature 20 of tractive magnet in the effect of magnetic field force and adhesive, armature 20 is pulled out main dead bolt 24 by master connecting-rod 23 from the main dead bolt hole of lock end housing, and the rocking bar 27 in the main lock body is under the counterclockwise elastic force effect of torsion spring 30, the end of rocking bar 27 in positioning sleeve 26 can be embedded in the pin-and-hole 25 below main dead bolt 24 front ends, main dead bolt 24 is stuck in is positioned at main lock body drawback lock position, make electromagnetic lock remain on open mode.Along with the facilities such as door that electromagnetic lock is housed are open, be separated from each other between electromagnetic lock main body and the lock end housing thereupon, secondary dead bolt 32 is under the blocking of the secondary dead bolt hole of lock end housing, and secondary dead bolt 32 is the center of circle with connecting axle 33, rotates counterclockwise and screws in main lock body front apron 16 inboards.Stagger fully when separating at main lock body and lock end housing body, secondary dead bolt 32 stops that because of not locked the end housing body bounce back into initial position under the effect of extension spring 31, this is the course of action of electromagnetic lock mechanism when unblanking.And when locking, because main dead bolt 24 is embedded in the main dead bolt pin-and-hole 25 because of the end of rocking bar 27 at positioning sleeve 26, main dead bolt 24 is stuck in the main lock body, can not hinder main lock body and the mutual contraposition of locking end housing.And secondary dead bolt 32 is exposed at the inclined-plane of electromagnetic lock front apron 16 outsides at closing time, will contact with lock end housing outward flange.Secondary dead bolt 32 is under the effect that is subjected to locking end housing outward flange and the mutual extrusion power of main lock front apron 16, and secondary dead bolt 32 makes through connecting axle 33 and be fixed on junction plate 34 moving linearly left above the slave connecting rod 35 that slave connecting rod spring 38 is compressed.Under the promotion of junction plate 34, rocking bar 27 will be that the center of circle is made clockwise direction and rotated with rocker shaft 28, make to pull out the pin-and-hole 25 of the termination of rocking bar 27 in positioning sleeve 26 below main dead bolt 24 front ends, no longer hinder the motion of main dead bolt.Be compressed when unblanking like this under the elastic force effect of master connecting-rod spring 29, main dead bolt 24 outwards ejects from main lock body.Along with the process of closing the door after the mutual mobile contraposition, main dead bolt 24 will spring in the lock end housing master dead bolt hole at main lock body and lock end housing.Secondary dead bolt 32 is under the elastic force effect of slave connecting rod spring 38, and when secondary dead bolt hole on the lock end housing and secondary dead bolt 32 aligned in position, secondary dead bolt 32 springs under the elastic force effect of attached bar spring 38 in the secondary dead bolt hole of lock end housing body.Return to initial position.The automatic blocking process is promptly accused and is finished like this.
The whole process with locking of unblanking of the above electromagnetic lock.This major and minor dead bolt project organization that the electromagnetic lock of magnet steel Puzzle electronic lock adopts, avoided traditional mechanical door lock to cause intensity not high because of there is the inclined-plane in dead bolt, the generation of problem such as easily dialled, prized, the magnet steel Puzzle electronic lock is improved obtaining essence aspect mechanical strength and the reliability.
Saidly in electromagnetic lock, be provided with by elastic shock attenuation isolating pad 19 between tractive magnet armature and the contacted operative end surface of iron core.Its positional structure is by shown in Figure 8.This elastomeric isolation pad 19 can not only play iron core and vibrations of the bump between the armature and the noise that causes when alleviating the tractive magnet adhesive, prolongs the parts effect in application life.And a prior purposes is to have overcome after the tractive magnet adhesive, though electromagnet coil is no longer switched on, but owing to still there being reasons such as remanent magnetism in tractive magnet iron core, armature and the coil, cause continuing to be pulled together between iron core and the armature 20, make timely this problem of reset lockout of main dead bolt 24 of electromagnetic lock.
