But the operating principle accompanying drawings of rail traffic platform shield door escape door safety emergent door lock of the present utility model is as follows:
Rail side release and block action:
After push rod 18 is pressed by the passenger, push rod 18 can contact with the handle 174 of pushing of lock body main body 17 by inner face, make and push handle 174 and move downward, thereby drive shifting block 173 motions of manually unblanking of lock body main body 17, the shifting block 173 of manually unblanking drives kinematic link 175 motion again, thereby drive link 15 and underdrive bar 16 move upward together in the drive, finally make the dead bolt 132 of top lock body 13 break away from top block 11, the lock pin 143 of bottom lock body 14 breaks away from bottom block 12, do the release campaign simultaneously, reach the purpose of release.
After push rod 18 was discharged by the passenger, the resistance of pushing handle 174 of lock body main body 17 disappeared, and itself can return to original position under the tension of return spring 176.When escape door is closed, thereby the dead bolt 132 of top lock body 13 is subjected to the resistance of top block 11 to return on the position of locking, the lock slide 134 of separating of top lock body 13 glides because the return spring in gravity and the lock body main body 17 176 conducts the pulling force acting in conjunction of coming, make the dead bolt 132 of the top arc limited block 1341 stuck top lock bodies 13 of separating lock slide 134 of top lock body 13, make it get back to locked position of coupler.
Specifically, in the time of last drive link 15 pulling release downwards slide block 134, separate lock slide 134 and move down, the arc limited block 1341 that causes separating lock slide 134 tops just in time is positioned at the lower edge of the semicircle inner chamber 1332 in bottom of dead bolt 133, as shown in Figure 7.Prop up dead bolt 133 according to this and make it be in spacing position and top block 11 is interlocked mutually, reach the purpose that locking is closed the door.When last drive link 15 upwards promotes to separate lock slide 134, separating lock slide 134 moves up, the arc limited block 1341 that causes separating lock slide 134 tops just in time is positioned at semicircle inner chamber 1332 inside, bottom of dead bolt 133, the internal chamber wall of dead bolt 133 can rotate 55 degree along the external surface of separating lock slide 134 top arc limited blocks 1341, this moment, dead bolt 133 was opened into released state, as shown in Figure 8.
The platform side release:
The platform personnel rotate key unlocking shifting block 172 rotations that the special-purpose lock of subway drives lock body main body 17 in platform side by private key, when rotating, pushes key unlocking shifting block 172 the soffit slip of the following shifting block 1743 of handle 174 with the edge, thereby what make lock body main body 17 pushes handle 174 rotational action together, later action is identical with the release action of rail side release, thus the release escape door.
