It is able to can be held by shake, such case is abnormally dangerous, also has a strong impact on that lift is run.Other door locks of in the market do not have self-locking work(
Can, and inside and outside can not unlock.
Utility model content
The purpose of this utility model is that solve the defects of above-mentioned prior art, there is provided one kind can automatically lock a door, prevent door
Lock slips off and being capable of the inside and outside car sliding door automatic door locking device unlocked.
The utility model provides a kind of car sliding door automatic door locking device, it is characterized in that：M, lock core
Component, back-moving spring；The m includes fixed support, closing piece is oriented to outer tube, elastic cylindrical pin, is fixed on car
On coaming plate；The lock core component includes closing piece and is oriented to inner tube, seven shape closing pieces, handle bar, handle steel ball, elastic cylindrical pin, installation
In on m；The back-moving spring is fixed on m elastic cylindrical pin and lock core component elastic cylindrical pin
On.
Wherein, lock core component moves up and down along m, is limited in closing piece and is oriented to outer tube.
Wherein, m is tightened up spring with lock core component and is connected, and lock core component is kept down tension.
Wherein, sliding door to lock core component extrude when, lock core component moves upwards, by door lock in the presence of back-moving spring
Firmly.
Wherein, in the presence of back-moving spring, prevent car sliding door in unstable motion from sliping off.
Wherein, under sliding door locking state, the unblock of handle steel ball can be opened the door upwards outside railway carriage or compartment in railway carriage or compartment.
It is of the present utility model to be beneficial in that：It effectively can prevent sliding door from sliping off, can be unlocked inside and outside railway carriage or compartment, energy
It is enough to lock a door automatically, largely improve the stability and security of the operation of car tower lift.
