Description
Technical field
The utility model relates to a kind of foot-treadle device of rail traffic vehicles.
Background technology
Existing foot-treadle device drives a rotatable axle sleeve by the rotating shaft of one " ∠ " shape, axle sleeve snaps into the recess that is positioned at stretcher side and locks stretcher, during release, by release, ride reverse push moving axis cover and depart from recess, stretcher resets under the effect of retracing spring.More complicated in this locking-unlocking device structure, and adopt round sleeve in the mode of side locking unreliable, after wearing and tearing or can automatic unlocking while bearing certain external force.
Utility model content
Technical problem to be solved in the utility model is: a kind of foot-treadle device of rail traffic vehicles is provided, adopts more reliably lock mode to pin stretcher at lower position, simplify locking-unlocking device structure simultaneously.
The utility model solves the technical scheme that its technical matters adopts: a kind of foot-treadle device of rail traffic vehicles, comprise the foot-operated and ratchet lock mechanism of stretcher, release, stretcher, release are ridden with seat and are articulated and connected, between stretcher and seat, elastomeric element is set, the restoring force of folded state is provided after providing and turning under stretcher this elastomeric element, ratchet lock mechanism is set between stretcher and seat, the down turning shape state of locking stretcher, release is ridden the ratchet by driving pawl lockout mechanism when depressing and is made the release of ratchet lock mechanism.
Further limit, ratchet lock mechanism comprises on ratchet on the seat of installation and stretcher and ratchet notches structure click-fit, and ratchet resets by elastomeric element, and ratchet locks the down turning shape state of stretcher by embedding ratchet notches structure.When stretcher turns to lower position, ratchet snaps in the ratchet notches structure on stretcher, stretcher locking, when depressing release when foot-operated, the foot-operated ratchet that promotes of release lifts, and ratchet 2-1 is deviate from from the ratchet notches structure 2-4 of stretcher 1, removes the lock-out state of stretcher.
Further limit, be fixed with two adapter plates on seat, be fixed with respectively and realize foot-operated major axis and the foot-operated minor axis that stretcher and seat are articulated and connected on two adapter plates, the both sides of stretcher are rotationally connected with foot-operated major axis and foot-operated minor axis respectively.
Further limit, the elastomeric element that the restoring force that returns back to folded state after turning under stretcher is provided is foot-operated retracing spring, foot-operated retracing spring is enclosed within on foot-operated major axis, one end of foot-operated retracing spring is fixed on stretcher, the other end of foot-operated retracing spring is fixed on setting nut, and setting nut is arranged on foot-operated major axis.
In order to make the reset of stretcher slowly smooth-going, avoid anxious the returning of stretcher to produce impulsive force, passenger is damaged, further limit, on foot-operated minor axis, be set with damper, damper is connected with stretcher with foot-operated minor axis respectively.
Further limit, the foot-operated the same side that is arranged on stretcher of ratchet and release, release is foot-operated coaxially installs with stretcher, ratchet is arranged on adapter plate by ratchet rotating shaft, the elastomeric element of reset ratchet is pawl restoring spring, and one end of pawl restoring spring is connected with ratchet, and the other end is connected with adapter plate, on adapter plate, have and carry out spacing limit shaft to release is foot-operated with stretcher, on limit shaft, cover has plastics stop collar.Release is foot-operated limits rotational angle by this plastics stop collar, when stretcher is upwards turned to the initial position of setting, by plastics stop collar, is propped up and no longer continues upwards to rotate simultaneously.
For improving train attendant's work efficiency, realize batter and step on return, further limit, ratchet is stepped on assembly by steel rope with the batter of release ratchet lock mechanism and is connected.
The beneficial effects of the utility model are: adopt ratchet lock mode to pin stretcher at lower position, lock more reliably, stretcher can be stepped on assembly release by batter after locking simultaneously, and release is more convenient.
