121 accommodation grooves 1223 worn.
Preferably, the accommodation groove 1223 is corresponded on the lower unlock mandril 121 be provided with a locating part 1211, the limit
One end of position part 1211 is connect with the lower unlock mandril 121, and the other end stretches out in the accommodation groove 1223, to stop
Lower unlock mandril 121 is stated around itself axial-rotation.Lower unlock mandril 121 can be stopped in moving process by the way that locating part 1211 is arranged
In rotate, reduce energy loss, improve working efficiency.
Referring to figs. 1 to Figure 10, it is based on above-mentioned design, when passenger needs when rail side opens platform screen door, passenger will
The handle 1112 of the handle solution lock set 111 of manual unlocking module 110 is opened from lid conjunction state, as passenger is to handle 1112
Operation drives the shaft 1114 to rotate, and is transmitted to worm screw 1301 by the connecting plate 1115, to drive 1301 turns of worm screw
It is dynamic, so that helicla flute 1305 upward sliding of the protrusion 1304 of the worm screw 1301 on the worm set 1302 is to helicla flute
Worm set 1302 is pushed to move up in shell 1111 behind 1305 edge, at this point, torsionspring 3074 is compressed；The snail
Rod set 1302 is moved up to drive unlock mandril 113 to move up, so that connecting with upper unlock mandril 113 upper solid
The spring base 1124 of component 112 is determined along 2104 upward sliding of sliding slot of the mainboard 2101 of bracket 1121, spring 1122 is compressed, if
The shift motion of upper unlock mandril 113 meets the requirement of unlock, the i.e. manual unlocking of the platform screen door of completion rail side.Specifically
Ground, the requirement of the unlock can lock supporting plate 1123 for the fixed top in upper unlock 113 top of mandril and contact with the top surface of munnion 20.Solution
After the completion of lock movement, the effect of external force is released, using spring performance, upper unlock mandril 113 is under the action of spring 1122
It moves downward, drives worm component 1113 to move downward, worm screw 1301 makes described convex under the action of torsionspring 3074
It rises 1304 along 1305 slide downward of helicla flute, automatically resets, restPose, the connecting plate 1115 is by the fortune of worm screw 1301
It is dynamic to be transmitted to shaft 1114 to drive shaft 1114 to rotate, to be resetted with fixed handle 1112, it is covered on shell 1111.
It is based on above-mentioned design in conjunction with Figure 11 referring to figs. 1 to Fig. 9, when station attendant need to open platform screen in platform side
When covering, skirting board 201 is kicked open, so that the keyhole 1231 of lock core of lock head component 123 exposes for station attendant insertion
Key, rotation key rotates keyhole 1231, while driving the tapered end for connecting and being connected to the keyhole 1231
The interconnecting piece 3502 of seat 1235 rotates, to drive lock core shaft 1234 and pivoted arm 1233 to rotate, to realize the pivoted arm 1233 and insert
The operation for entering the key of the keyhole 1231 is interlocked and is rotated, a top margin 3301 of the pivoted arm 1233 and lower knock-off joint 1232
Side separation, another top margin 3301 of the pivoted arm 1233 jacks up lower knock-off joint 1232 with rotation, so that lower unlock top
Bar 121 moves up, to drive worm screw 1301 to move up, so that the protrusion 1304 of the worm screw 1301 is along the worm set
Push worm set 1302 in upward in shell 1111 after helicla flute 1305 upward sliding to the edge of helicla flute 1305 on 1302
It is mobile, at this point, torsionspring 3074 is compressed；The worm set 1302 is moved up to drive unlock mandril 113 to moving up
