When the impact block does not impact the stop block, one end of the lever is clamped into the annular groove on the first push rod under the elastic force of the sixth spring, and the third spring at the end part of the first push rod is in a compressed state at the moment.

When the impact block impacts the stop block, the stop block drives the impact rod to move towards the direction close to the glass to impact the glass, one end, in contact with the inclined surface of the impact rod, of the lever is pushed by the inclined surface at the end of the impact rod to move upwards, so that one end, in which the lever is clamped into the annular groove in the first push plate, of the lever moves downwards to be separated from the annular groove, at the moment, under the elastic force of the third spring, the first push rod moves towards the direction close to the stop block to enable the first push rod to contact the stop block, and after the impact rod impacts the glass, the impact rod moves towards the direction away from the glass under the elastic force of the first spring to recover the original position;

The principle and the beneficial effect of the rail transit escape device of the embodiment are as follows:

when the rail transit vehicle has a dangerous situation and needs to break the window for escaping, the handle 21 is held by hand to remove the safety hammer to enable the conical head 202 to strike the window glass 10 towards the glass 10, when the glass 10 is struck by the safety hammer, the conical head 202 on the safety hammer is rebounded by the glass 10 to enable the conical head 202 to overcome the elasticity of the elastic piece 203 to move towards the direction close to the bottom of the first slideway 201 to extrude the wireless switch button end 205, the extruded wireless switch button end 205 is triggered to send an electrifying signal to the wireless switch receiving end, the wireless switch receiving end receives the electrifying signal to control the first electromagnet 348 to be communicated with the battery to enable the first electromagnet 348 to generate magnetic force to adsorb the metal blocking rod 345, the metal blocking rod 345 overcomes the elasticity of the second spring 346 to move towards the direction close to the first electromagnet 348 under the magnetic force adsorption of the first electromagnet 348 to enable the inner end of the metal blocking rod 345 to be separated from the fixed rod 343, and under the elasticity of the first torsion spring 342, the first rotating shaft 341 rotates rapidly to drive the impact block 349 to rotate to impact the stop block 302, so that the stop block 302 drives the impact rod 31 to impact the glass 10 from the side end of the glass 10, and the toughened glass 10 has the characteristic that the impact from the side corner of the glass 10 is more easily broken, so that the glass 10 is more easily broken by the impact rod 31 impacted from the side.

When the striking block 349 does not strike the stop block 302, one end of the lever 4011 is caught in the ring groove 4010 of the first push rod 40 under the elastic force of the sixth spring 4012, and the third spring 401 at the end of the first push rod 40 is in a compressed state.

When the impact block 349 impacts the stop block 302, the stop block 302 drives the impact rod 31 to move towards the direction close to the glass 10 to impact the glass 10, the end, in which the lever 4011 is in contact with the inclined surface of the impact rod 31, of the impact rod 31 is pushed by the inclined surface of the end part of the impact rod 31 to move upwards, so that the end, in which the lever 4011 is clamped into the annular groove 4010 on the first push plate 406, of the lever moves downwards to separate from the annular groove 4010, at this time, under the elastic force of the third spring 401, the first push rod 40 moves towards the direction close to the stop block 302 to make the first push rod 40 contact the stop block 302, and after the impact rod 31 impacts the glass 10, the impact rod 31 moves towards the direction away from the glass 10 under the elastic force of the first spring 33 to restore the original position;

when the first push rod 40 moves towards the direction close to the stop block 302, the stop pin 408 moves along with the first push rod 40, the push plate 406 cannot move due to the contact between the push plate 406 and the stop plate 405, the stop pin 408 is pressed back into the second slide way 407 by the push plate 406 when the push plate 406 moves along with the first push rod 40 and passes through the push plate 406, the stop pin 408 is pushed by the fifth spring 409 after passing through the push plate 406, so that the upper end of the stop pin 408 extends out of the second slide way 407, and at the moment, when the first push rod 40 is pushed to move towards the direction close to the third spring 401 again, the push plate 406 moves along with the first push rod 40 at the same time under the stop of the stop pin 408;

the stopper 302 drives the striker 31 to move towards the direction close to the glass 10 and simultaneously pushes the insertion rod 426 to move towards the direction close to the glass 10, so that the end of the insertion rod 426 inserted into the first insertion hole 424 moves towards the direction close to the glass 10 and is separated from the bearing seat 422, the end of the insertion rod 426 far away from the seventh spring 425 falls down under the self weight of the insertion rod 426, the cam 42 rapidly rotates under the elastic force of the second torsion spring 423 after being not limited by the insertion rod 426 and pushes the stopper 302 to enable the stopper 302 to move towards the direction close to the glass 10 again, at the moment, the first push rod 40 is contacted with the stopper 302, when the stopper 302 moves towards the direction close to the glass 10 again, the first push rod 40 is pushed to move towards the direction close to the third spring 401, under the block of the stop pin 408, the push plate 406 simultaneously moves with the first push rod 40, the lower end of the push plate 406 is provided with an inclined surface matched with the inclined surface at the upper end of the second push rod 403, and when the push plate 406 moves towards the direction close to the third spring 401, the second push rod 403 moves downwards to enable the push plate 403 to be adhered to the side wall of the carriage The pieces of glass 10 are pushed away from the sidewall of the carriage to prevent the head of the evacuee from being scratched.

When the striking block 349 strikes the stopper 302, the stopper 302 moves towards the direction close to the glass 10 to press the button switch 47 to connect the second electromagnet 46 with the battery, the second electromagnet 46 generates magnetic force to enable the sliding column 44 to slide towards the direction close to the second electromagnet 46, the sliding column 44 slides towards the direction close to the second electromagnet 46 to enable the first torsion spring 342 to be separated from the sliding column 44 to lose the elastic force effect on the first rotating shaft 341, and the striking block 349 rapidly falls under the self weight without affecting the movement of the stopper 302.

With the current conventional adoption safe hammer openly strike with window glass break into pieces and compare, this scheme has following beneficial effect at least:

1. when the safety hammer is used for knocking the glass from the front side, the glass is beaten from the side face of the glass, so that the glass is broken more easily, the glass breaking speed is increased, more escape time is strived for safe escape of passengers, and the safe escape efficiency is increased.

2. After the glass is hit from the side, the cam is rotated to move the second push rod downward to clean away the glass fragments adhered to the glass along the side wall of the vehicle compartment, so as to prevent the head from being scratched by the glass fragments adhered to the side wall of the vehicle compartment when a passenger escapes through the window.
