Anti-bias energy-absorbing locking device is demonstrate,proved longitudinally to be locked.
Further, guide rod is symmetrical, can constrain the collapse energy-absorption pipe of square plate steady ordered, while being also equipped with preventing
The ability of inclined and bending resistance.
Further, the stop block can limit the angle of rot rotation.
The beneficial effects of the invention are as follows：The present invention can prevent horizontal fold behavior between vehicle, it is to avoid train is because of wheel
Constrain de-orbiting and occur derailment accident, effect becomes apparent on curve track；Can stablize and controllable absorption is touched
Hit energy, it is ensured that vehicle end portion structure integrality, strengthen the passive safety of train；Device is locked without departing from and limited after implementing
Rotational angle between vehicle processed, constrains vehicle relative motion within the specific limits.
