Moved in chute 49, the linear motion of pedal 5 can not only be played a part of being oriented to and positioned, while had to pedal 5
Upward support force.
Operation principle is as follows：
When attendant closes train door 2, attendant starts reducing motor 41, and reducing motor 41 is started working and driven
Rotary shaft 43 rotates with the gear 42 for being fixed on the lateral wall of rotary shaft 43, passes through the intermeshing band carry-over bar of the rack 44 of gear 42
44 and pedal 5 to away from platform 6 position withdraw.During pedal 5 is withdrawn, at the abutted position of movable block 46 on pedal 5
The height of rat gradually increases, so as to promote movable block 46 constantly to insert inside blind hole 21, while constantly compression spring 22,
Realize the function of the locking train door 2 of pedal 5.Before attendant opens train lock 3, first start reducing motor 41 and rotate backward, subtract
Speed motor 41, which is started working, drives rotary shaft 43 to be rotated with the gear 42 for being fixed on the lateral wall of rotary shaft 43, passes through the rack of gear 42
44 intermeshing band carry-over bar 44 and pedal 5 stretches out to the direction of platform 6.During pedal 5 stretches out to platform 6, pedal 5
The raised height in upper surface gradually reduces, while spring 22 gradually discharges elastic potential energy and promotes movable block 46 to be connected on pedal 5
Surface, it is gradually reduced so as to the height of movable block 46, when the height of movable block 46 is less than 4 upper level of storage case, pedal 5
The locking of corresponding train door 2 releases.When the fin 51 of pedal 5 is embedded in the concave rib 61 of platform 6, attendant can open train door
2 allow passenger freely to get on or off the bus.
