Description
Technical field
It the utility model is related to a kind of tripper of vehicle doorn, more particularly to a kind of end of the passive locking of train-door system
Portion's tripper.
Background technology
At present on rail vehicle, public transit vehicle door, the vehicle doorns for using worm drive, this kind of vehicle doorn can be random more
Switch, locking system can be set for the safety of passenger, and passive locking system is good and simple in construction due to locking effect
By wide selection.But in case of emergency, it is necessary to locking of the emergency unchaining locking device to screw mandrel is opened the door, now just need
Set one can emergency operation tripper.Existing tripper is usually mounted to the middle part or end of screw mandrel, but pacifies
Tripper loaded on middle part is a kind of indirect tripper, and tripper stirs nut, drives screw mandrel to rotate and realizes unblock.Should
Transmission of the tripper due to relying on nut in the middle part of kind, the reliability of abrasion meeting this kind of device of extreme influence of nut；And set
In the middle part of screw mandrel, structure is too fat to move, poor universality；Serious wear at the cooperation of screw mandrel and nut so that the big motion of screw rod jitter
It is unstable.
In order to solve the Chinese utility model patent that this problem has Authorization Notice No. to be CN202117438U《Vehicle is automatic
The end unlocking device of locking mechanism》Disclose a kind of end unlocking device, including torsion spring, axle sleeve, solution lock core, solution lockwheel, dial
Bar, restoring board, connecting shaft, dynamic clamping head and quiet clamping head, support, damper and alignment pin；Wherein：Torsion spring is socketed in axle sleeve and conciliates lock core
On, one end of torsion spring is fixed on axle sleeve, and the other end is fixed in solution lockwheel, torsion spring and axle sleeve interference fit, torsion spring and unblock
