The specific embodiment
The structure of electric lock:
Contrast accompanying drawing 1-4, the structure of electric lock comprises lock fork assembly 1, moving assembly 2, and wherein lock fork assembly 1 is installed on the fixation side box, and moving assembly 2 is installed on a machine.
Contrast accompanying drawing 5-7, the structure of lock fork assembly 1 comprises electromagnet 3, ratchet synchronizing wheel 4, manual unlocking switch 5, is locked into bit switch 6, lock fork torsion spring 8, lock fork 9, ratchet 10, underframe 11, the synchronous rotor plate 12 of lock fork are installed, wherein lock fork 9 is synchronizeed rotor plate 12 and is connected with lock fork by square shaft, realize synchronous the rotation, simultaneously, lock fork torsion spring 8 one ends are synchronizeed rotor plate 12 and are connected with lock fork, an end of lock fork torsion spring 8 with underframe 11 be installed be connected, after release, the lock fork automatic rotating.
Contrast accompanying drawing 8-9, the structure of moving assembly 2 comprises mobile version 13, solution lock dog 14, shifting axle 15, stage clip 16, support 17, the pivoted housing 18 installed, and wherein separates lock dog 14 and is assemblied in together on support 17 by screw and stage clip 16; Separate lock dog 14 under the pulling of wire rope, move right, compression press spring 16; Unclamp wire rope, separate lock dog 14 and automatically reset under the effect of stage clip 16.
The operating principle of electric lock and the course of work:
Thereby electric lock is to realize locking or unlocking function by door control system by the electric lock of controlling wherein.The lock fork assembly is installed in gate fixation side box, and moving assembly is installed on a machine.
When gate was carried out the normal door order, door control system sent enabling signal, and electromagnet 3 adhesives drive ratchet and move with ambulatory claw, and the lock fork locked position is left in ratchet 10 motions simultaneously, makes lock fork freedom of entry state; Ratchet triggers with ambulatory claw and is locked into bit switch 6, sends electronic unlocking signal, and this moment, locking states was removed, the motion of door machine drives the moving assembly motion of a machine that is installed on, pivoted housing skids off from the lock fork of free state, thereby realizes release, and lock fork is by being positioned unlocked position simultaneously.
When order is normally closed the door in the gate execution, door control system sends the pass gate signal, the door body drives the moving assembly that is installed on a machine and moves, pivoted housing clashes into the lock fork 9 that is in the unlocked position, and lock fork resets to locking states, and ratchet 10 resets simultaneously, this moment, thereby ratchet 10 blocked lock fork lock fork locking, ratchet leaves the trigger position that is locked into bit switch with ambulatory claw simultaneously, discharges the electric locking signal, thereby realizes locking.
When the gate manual unlocking, the wire rope on gate pulls the solution lock dog in moving assembly to move, and separates lock dog and moves triggering manual unlocking switch, rotates simultaneously ratchet 10, makes ratchet break away from locked position, and lock fork is rotated, thereby realizes the gate manual unlocking.
Whole electric lock is controlled by door control system, and electromagnet is power source.The lock fork assembly is installed on the fixation side box, and moving assembly is installed on a machine.
Electromagnetic actuation, the ratchet synchronizing wheel drives rotating shaft, and rotating shaft drives ratchet, and ratchet leaves the locked position of lock fork, and moving assembly can be moved freely, thereby realizes the function of release, and lock fork remains on unlocked position.
When the door body was closed, the pivoted housing of moving assembly clashed into the lock fork of unlocked position, and lock fork resets, and ratchet pawl reset, be fixed in lock fork the pivoted housing of moving assembly, thereby realize locking simultaneously, and this moment, electromagnet was not worked.
When manual unlocking, manual unlocking device drives separates the lock dog motion, separates lock dog and makes ratchet leave the lock fork locked position, moving assembly can be moved freely, thereby realize manually.
The Main Function of electric lock is: locking effect, electromagnet release effect, manual unlocking effect.The lock fork assembly generally is installed in the gate fixation side, plays the initiatively effect of locking, electronic release, and sends the locking states signal for the external system of response; Moving assembly generally is installed on a machine, plays passive locking, the effect of manual unlocking.
