1) signal feedback whether the coil assembly is normal: the microswitch I9 arranged on the coil supporting frame assembly 8 can judge whether the coil assemblies (as shown in figures 1 and 2, two coil assemblies 12 are respectively a main coil assembly 12.1 and a standby coil assembly 12.2, the main coil assembly 12.1 and the standby coil assembly 12.2 are both arranged on the coil supporting frame assembly 8, the main coil assembly 12.1 and the standby coil assembly 12.2 are both provided with thermal protection resistors and are independent of each other, when the main coil assembly 12.1 fails, the standby coil assembly 12.2 can be in relay locking in a low level state, the main coil assembly 12.1 generates heat, when electromagnetic attraction is reduced, the state and the use of the standby coil assembly are not influenced, the high-level to low-level power switching time is within 1s, the main coil assembly 12.1 can realize the function in the normal locking working step, when the main coil assembly 12.1 is switched to the standby coil assembly within 300 milliseconds, the standby coil assembly 12.2 can realize the relay locking function of the invention), after the coil component is electrified, electromagnetic force is generated to attract the armature 7 and the magnet box component 5 arranged on the armature 7, the magnet box component 5 triggers the microswitch I9, if the coil component cannot generate magnetic force after being electrified (the damage of the coil component is indicated), the magnet box component 5 cannot trigger the microswitch I9, a signal of the microswitch I9 is abnormal (namely the signal is not in accordance with the preset logic of a monitoring system, the preset logic of the monitoring system is shown in figures 15 and 16), and the monitoring system identifies (the monitoring system is the prior art);
2) unlocking and unlocking signal feedback: install micro-gap switch II 20 in mount subassembly 19 one side and can direct feedback and actuate the structure position and judge whether the electromagnetic lock unblanks or locks, the principle is: when the electromagnetic lock catch is powered on, the locking assembly 15 is hinged to the fixed frame assembly 19 and rotates to move, when the locking assembly leaves the micro switch II 20, a locking signal is obtained, and meanwhile the locking assembly moves to the position below the locking transmission rod assembly 21, at the moment, the locking assembly 15 abuts against the locking transmission rod assembly 21 (namely, the locking transmission rod assembly 21 is limited), when the locking transmission rod assembly 21 abuts against, the lock catch 23 is also fixed by being locked, and the lock catch 23 is fixed, namely, the electromagnetic lock catch is locked (the locking logic is shown in figure 15);
on the contrary, after the power is cut off, the locking assembly 15 returns to the original position under the action of the torsion spring II 14, the micro switch II 20 is triggered, an unlocking signal can be obtained, the limit of the locking transmission rod assembly 21 is released, and the electromagnetic lock catch is unlocked (the unlocking logic is shown in figure 16).
3) And (3) door opening and closing signal feedback: the microswitch III 18 can feed back whether the door is closed or not; the principle is as follows: when the door is closed, the bolt on the door props against the bolt transmission component 25 of the electromagnetic lock, the second V-shaped surface 25.1 of the bolt transmission component 25 pushes the first V-shaped surface 29.1 on the transmission block 29 to make the bolt transmission component move linearly, the micro switch III 18 is triggered, and the electromagnetic lock feeds back a door closing signal to be identified by a monitoring system. Otherwise, the bolt on the door is separated from the bolt transmission assembly 25 of the electromagnetic lock, the switch button of the microswitch III 18 rebounds, and the electromagnetic lock feeds back a door opening signal to be identified by the monitoring system.
Therefore, the invention has the capability of feeding back whether the electromagnetic lock coil assembly is normal or not, feeding back whether the electromagnetic lock is unlocked or locked or not, and feeding back whether the door is closed or not.
As shown in fig. 1 to 12, the working steps of the active anti-theft electromagnetic lock with signal feedback in the actuating structure according to the present invention are as follows:
1) and locking the working step:
when the door is closed, the door latch bolt is inserted into the buckle 23, and abuts against the latch bolt driving assembly 25, and the latch bolt driving assembly 25 is rotated. The second V-shaped surface 25.1 of the bolt transmission component 25 actuates the V-shaped surface of the transmission block 29, so that the transmission block 29 moves linearly to touch the microswitch III 18, the microswitch III 18 generates an on-off signal to the control system, the control system can identify that the bolt on the door is inserted into the lock catch 23, the control system (namely the monitoring system) energizes the coil component 12 according to the preset logic (the preset locking logic of the control system is shown in figure 15), the coil component 12 forms a closed magnetic circuit under the action of the coil support frame component 8, overcomes the elastic force of the cylindrical spiral spring 6, attracts the armature 7 and the magnet box component 5 to move towards the coil component 12, until the armature 7 props against the coil support frame component 8, the magnetic attracting movement generated by the coil component 12 is finished, at the moment, the magnet box component 5 triggers the microswitch I9 along with the movement of the armature 7, and the microswitch I9 generates an on-off signal to the microswitch I9, the control system can recognize that the coil assembly 12 is operating properly. The actuating rod assembly 11 moves towards the coil assembly 12 along with the armature 7 in the attracting process and is linked with the safety block assembly 16, and at the moment, the safety block assembly 16 is separated from the locking assembly 15 under the action of the torsion spring I17 and is located at a position where the safety block assembly abuts against the locking assembly 15, so that the safety function is achieved. When the locking assembly 15 rotates around the shaft to the lower part of the locking transmission rod assembly 21 under the action of the torsion spring II 14, the locking assembly 15 is just limited by the fixed frame assembly 19 to move, at the moment, the locking assembly 15 is separated from the microswitch II 20, the microswitch II 20 generates an on-off signal to be sent to the control system, and the control system can recognize that the locking assembly 15 works normally. The locking transmission rod assembly 21 can only be limited to the rotation movement direction of the locking assembly 15, when the locking transmission rod assembly 21 is limited to the locking assembly 15, the rotation movement direction of the lock catch 23 is also limited by the locking transmission rod assembly 21, and the active anti-theft electromagnetic lock catch with signal feedback is locked in the actuating structure.
2) And unlocking the lock:
when the door needs to be opened, the coil assembly 12 is powered off, the armature 7 returns to the original position under the elastic force action of the cylindrical spiral spring 6, the magnet box assembly 5 moves along with the armature 7 to leave the microswitch I9, the microswitch I9 generates an on-off signal to the control system, the control system can recognize that the coil assembly 12 stops working, and the control system (namely the monitoring system) powers off the coil assembly 12 according to preset logic (the preset unlocking logic of the control system is shown in figure 16). The actuating rod assembly 11 arranged on the armature 7 is linked with the safety block assembly 16, the safety block assembly 16 is linked with the locking assembly 15, the locking assembly 15 is separated from the lower part of the locking transmission rod assembly 21, and the rotation limitation of the locking transmission rod assembly 21 is removed. Accordingly, the rotation restriction of the lock 23 by the lock transmission lever assembly 21 is also released. Along with the fact that the locking assembly 15 leaves the lower portion of the locking transmission rod assembly 21, the micro switch II 20 generates an on-off signal to the control system, the control system can recognize that the active anti-theft electromagnetic lock catch with the signal feedback of the actuating structure is in an unlocking state, operations such as door handle rotation and key insertion unlocking are not needed, and the door can be opened when being pushed.
3) And door opening signal feedback:
when the door is opened, the lock tongue on the door leaves the lock catch 23 and is separated from the lock tongue transmission assembly 25, the lock tongue transmission assembly 25 is rotated and returned to the original position, the second V-shaped surface 25.1 of the lock tongue transmission assembly 25 is returned to be parallel to the first V-shaped surface 29.1 of the transmission block 29, the transmission block 29 is pushed away linearly under the action of contact thrust on the micro switch III 18, the micro switch III 18 is not touched, the micro switch III 18 generates an on-off signal to the control system, and the control system can recognize that the door is opened.
It should be noted that the control system recognizes the on/off signal and is easy to be powered on and off according to the preset logic, and therefore, the detailed description thereof is omitted.
