But the operating principle accompanying drawings of locking device for screen door in rail transit of the present utility model is as follows:
The locking Principle of Process of closing the door of the present utility model is: when door opening state, left and right sides lock dog 21 opens under the pulling force of lock dog back-moving spring 23, and break away from left and right sides dead bolt 22 this moment, as shown in Figure 2.When double door is closed, being installed in the spacing pin 6 of left and right sides dodge gate on the double door moves to left and right sides lock dog 21 and contacts, continuing motion rotates up to promoting lock dog, the underarm 212 of lock dog slips over dead bolt, and dead bolt rotates under the effect of lock dog underarm, when forwarding certain angle to, when the lock dog underarm slips in the latch hook 221 of dead bolt, the resilience under the effect of dead bolt back-moving spring 24 of the ineffective power of dead bolt, lock dog underarm embed in the dead bolt, and this moment, the rotation of lock dog was limited.The spacing pin 6 of dodge gate moves to this moment, and dodge gate is closed stop motion, in the crooked shape notch on the spacing pin 6 of dodge gate rotates in lock dog and limits between the underarm, thereby realizes locking.
The Principle of Process that release of the present utility model is opened the door is: dead bolt trundle 33 and latch bolt spring pin 241 are installed on left and right sides dead bolt 22, and dead bolt trundle 33 and latch bolt spring pin 241 are moving in the restricted portion of corresponding circular arc waist hole on the lock 1.The dead bolt slewing area also is limited.On the spring catch 241 on the dead bolt dead bolt back-moving spring 24 is installed, dead bolt is in all the time and opens maximum rating under the tension of dead bolt back-moving spring 24.All the time be in the lock state after lock dog slips into dead bolt, the pulling force that overcomes resistance and dead bolt back-moving spring 24 when dead bolt rotates, and throws off the lock dog underarm, and the restriction of lock dog underarm is disengaged.The power that lock dog rotates is the power during with the door folding from the spacing pin 6 of dodge gate mainly, and release is opened the door thereby lock dog rotates realization under the drive of the spacing pin 6 of dodge gate.The power that dead bolt rotates is provided by electromagnet 31, when control system provides when opening the door instruction, and electromagnet 31 energisings, electromagnetic core 311 shrinks under magneticaction, drives the electromagnetism that is connected with electromagnet 31 and separates lock slide 32 and move.Slide block 32 drives trundles 33 motions, and restriction to lock dog is untied in the dead bolt motion that rotates under the drive of trundle 33.The 21 rotation releases of the spacing pin 6 drive lock dogs of dodge gate are finished when the driven by motor dodge gate that opens the door is opened.When electromagnet outage rear slider 32 resets under the spring force effect, sell tongue and also reset to original state.Lock dog also is in initial open configuration after opening the door.
The extraction principle of door-closing in-place signal of the present utility model is: the door-closing in-place signal is provided by left and right sides travel switch 51, when lock dog rotates under the promotion of the spacing pin 6 of dodge gate, sliding pin 53 can move in the horizontal concrete chute 521 of guide pad 52, when the lock dog underarm moves to lock tongue slot hook position, the plunger 511 of guide pad 52 front end crush stroke switches 51, plunger 511 shrinks and triggers travel switch 51 conductings, notice shield door controller dodge gate is locked, the signal of locking is provided by the travel switch that is installed in the right and left respectively about this lock, therefore can detect the left and right door lock-out state respectively.
The Principle of Process of manual unlocking of the present utility model is: when power-off or off-position, if dodge gate is in locking bit, can adopt the hand-operating unlocking mechanism release to open the door.Promote connecting screw rod 43 and in SLIDE GUIDE 41, slide when jacking block 45 is subjected to open Door by Hand elastic force that the pressure of device overcomes manual unlocking back-moving spring 44 of dodge gate, thereby promote 42 motions of manual unlocking slide block, the trundle 33 that manual unlocking slide block 42 promotes on the left and right sides dead bolt 22, the drive dead bolt rotates, when latch hook on forwarding dead bolt to and lock dog underarm break away from, realize release.The plunger 541 of manual unlocking slide block 42 compression travel switch 54 in motion process, plunger activated connection signal when unblanking fully.
