Abstract
A kind of emergency unlocking device when folding door lock fails, including release lever, it is characterized by: release lever is movably connected on handle mounting cup, a cable quadrant is connected on release lever, cable quadrant is fixedly connected with an angle bar, and angle bar is connect with kinematic link lower end on one side, another side connects limit switch, kinematic link upper end connects a cam, and unlocking link is connected on cam, is equipped with reset spring above unlocking link.Release lever is pulled, release lever power is successively transmitted to cable quadrant, angle bar, kinematic link, cam, unlocking link, lock tongue, realizes car door unlock.After car door opening, emergency release handle is unclamped, unlocking link is withdrawn into locking plate by reset spring, and emergency release handle resets, and mechanism is restored to home position, and limit switch cancels triggering, and car door emergency release process terminates.It solves the problems, such as that door lock failure can not open, avoids vehicle operation late.
Description
Technical field
The present invention relates to rail traffic vehicles car door trippers, unlock when failing more particularly, to a kind of folding door lock
Device.
Background technique
Folding door lock used in rail traffic vehicles often breaks down or key fracture is in lockhole, leads to car door
The case where appearance can not open.And this folding door be frequently used for driver enter drivers' cab by door, so car door can not be beaten
It opens, will cause that vehicle is late, influence the operation of subsequent all vehicles, bring huge trouble to passenger's trip.
Summary of the invention
The object of the present invention is to provide emergency unlocking devices when a kind of failure of folding door lock, can fail in door lock, door
When can not open, by pulling emergency release handle, lock tongue is headed into lock body, realizes that door is normally opened.
For achieving the above object, the present invention provides emergency unlocking device when a kind of folding door lock fails, including solution
Lock handle, it is characterised in that: release lever is movably connected on handle mounting cup, and a cable quadrant, bracing wire are connected on release lever
Disk is fixedly connected with an angle bar, and angle bar is connect with kinematic link lower end on one side, and another side connects limit switch, and kinematic link upper end connects
A cam is connect, unlocking link is connected on cam, is equipped with reset spring above unlocking link.
The kinematic link upper and lower ends are separately connected a bulb-shaped universal shaft.
The cam is movably connected on bracket by shaft, and a pivoted arm is also fixedly connected on cam, and pivoted arm one end is living
It is dynamic to be connected on bracket, the universal axis connection of upper end bulb-shaped of the other end and kinematic link.
The through hole that described unlocking link one end passes through bracket is connect with cam, and the other end protrudes into locking plate.
The present invention connects release lever by cable quadrant, and kinematic link both ends universal shaft is separately connected angle bar and cam, convex
It takes turns the other end and connects unlocking link, reset spring is resetted for unlocking link.When door lock fails, lock tongue can not be recovered in lock body
When portion, crew member pulls release lever, and release lever drives the cable quadrant connected at its back that angle bar is driven to move upwards, angle
Iron connects kinematic link, while touching limit switch, and driver's emergency release is prompted to be operated.Kinematic link band moving cam, it is convex
Wheel ejects unlocking link, and unlocking link is stretched out by the aperture on locking plate, and lock tongue is shifted onto inside lock body, realizes car door solution
Lock.After car door opening, emergency release handle is unclamped, unlocking link is withdrawn into locking plate by reset spring, emergency release handle
It resets, mechanism is restored to home position, and limit switch cancels triggering, and car door emergency release process terminates.Solves door lock failure
The problem of can not opening, avoids vehicle operation late.
Detailed description of the invention
Fig. 1 is the front view of device of the present invention.
Fig. 2 is the rear view of device of the present invention.
Specific embodiment
Referring to Fig.1, Fig. 2, the specific embodiment of the invention include release lever 1, cable quadrant 3, angle bar 4, limit switch 5,
Kinematic link 6, cam 7, reset spring 8, unlocking link 2.Release lever 1 is movably connected on handle mounting cup 12, unlocks hand
A cable quadrant 3 is fixedly connected on handle, cable quadrant 3 is fixedly connected with an angle bar 4, and 4 one side of angle bar passes through bulb with 6 lower end of kinematic link
Type universal shaft 11 connects, and another side connects limit switch 5, and 6 upper end of kinematic link similarly passes through the connection of bulb-shaped universal shaft 11
One pivoted arm 10, pivoted arm 10 are movably connected on bracket 13, are coaxially provided with a cam 7 with pivoted arm 10, and cam 7 and pivoted arm 10 are simultaneously again
It is fixed together, therefore, cam 7 and pivoted arm 10 rotate synchronously, and 7 upper end of cam connects unlocking link 2, and unlocking link 2 is set above
There is reset spring 8.The through hole 14 that described 2 one end of unlocking link passes through bracket is connect with cam, and the other end protrudes into locking plate 9
It is interior.
Release lever is operation interface, is operated with for crew member, and other mechanisms are mounted on a pars intramuralis.It draws
Drum connects release lever, and kinematic link both ends universal shaft is separately connected angle bar and cam, and the cam other end connects unlocking link,
Reset spring is resetted for unlocking link.
When door lock fails, and lock tongue can not be recovered to inside lock body, crew member pulls release lever shown in Fig. 1,
Release lever drives the cable quadrant connected at its back, and cable quadrant drives angle bar to move upwards, and angle bar connects kinematic link, simultaneously
Limit switch is touched, driver's emergency release is prompted to be operated.Kinematic link drives pivoted arm rotation, is fixedly connected with pivoted arm and together
The cam of axis rotates, and unlocking link is ejected, and unlocking link is stretched out by the aperture on locking plate, and lock tongue is shifted onto lock body
Portion realizes car door unlock.
After car door opening, emergency release handle is unclamped, unlocking link is withdrawn into locking plate by reset spring, emergency release
Handle resets, and mechanism is restored to home position, and limit switch cancels triggering, and car door emergency release process terminates.
