Isolation lock used in currently marketed door device, it can be operated under any circumstance, i.e. car door
It can also be operated in the case of opening, can so there is the potential safety hazard of enabling sport car.
The content of the invention
The invention aims to overcome the deficiencies in the prior art, there is provided a kind of rail traffic vehicles door system isolation lock
Protection device, it can be locked in car door opening isolation lock system, isolation lock is not operated, prevent the peace of enabling sport car
Full hidden danger.
Realizing a kind of technical scheme of above-mentioned purpose is：A kind of protection device of rail traffic vehicles door system isolation lock,
Including the locking device at the top of door frame and the collision block at the top of door-plate；
The locking device includes latch hook, back-moving spring and cam；The cam is with isolating lock protective device connection, in institute
State and lock hook slot is offered on cam；The door frame is provided with latch hook support, and the latch hook passes through the latch hook support, the latch hook
End be connected in the lock hook slot, the afterbody of the latch hook stretches out the latch hook support；The back-moving spring is arranged on institute
State on latch hook；
The collision block faces the afterbody of the latch hook, when the door-plate closes in the door frame, the collision block pair
The afterbody of the latch hook produces extruding, the end of the latch hook is departed from the lock groove.
Further, the cam is rotatably arranged at the top of the door frame, and the cam is provided with the triggering of evagination
Structure..
Further, the collision block includes connection sheet and hits post, and the connection sheet is fixed by screws in the door-plate top
Portion, the post that hits are connected with the connection sheet, and it is axially vertical with the plane of the connection sheet, and described hit faces in the middle part of post
The afterbody of the latch hook.
The protection device of a kind of rail traffic vehicles door system isolation lock of the present invention, when the door closes by door-plate
The collision block of installation hits the afterbody of latch hook, latch hook is departed from the lock groove of cam, can freely be rotated with liberating cam, from
And enabling cam to trigger isolation lock is operated it.After car door opening, back-moving spring resets latch hook, again
It is connected in the lock hook slot of cam, pinning cam makes cam not rotate so that isolation lock can not operate.Such structure design
So that being unable to operation isolation lock under door opening state, prevent the potential safety hazard of enabling sport car.

Embodiment
In order to preferably understand technical scheme, below by specifically embodiment and with reference to accompanying drawing
It is described in detail：
Referring to Fig. 1, a kind of protection device of rail traffic vehicles door system isolation lock of the present invention, including positioned at door frame
The locking device and the collision block 2 positioned at the top of door-plate 4 at 3 tops.
Fig. 2 to Fig. 5 is referred to, locking device includes latch hook 11, back-moving spring 12 and cam 13.Cam 13 is rotatable to be set
Put on door frame 3, cam is provided with the trigger architecture 131 of evagination, and lock hook slot 132 is offered on cam.Trigger architecture 131 refers to
To isolation lock protective device 5.Door frame 3 is provided with latch hook support 1, and latch hook 11 passes through latch hook support 1, and the end 111 of latch hook 11 is blocked
It is connected in lock hook slot 132, the afterbody 112 of latch hook 11 stretches out latch hook support 1.Back-moving spring 12 is arranged on latch hook 11.
Collision block 2 includes connection sheet 21 and hits post 22, and connection sheet 21 is fixed by screws in the top of door-plate 4, hits post 22 with connecting
Contact pin 21 connects, and it is axially vertical with the plane of connection sheet 22, and the middle part for hitting post 22 faces the afterbody 112 of latch hook 11.
When door-plate closes in door frame, hit post 22 and extruding is produced to the afterbody 112 of latch hook 11, make the end of latch hook 11
111 depart from lock groove 132.Now cam 13 is free to rotate, and its trigger architecture 131 can trigger isolation lock protective device 5, to this
Door-plate is bypassed.
When door-plate is opened, hit post 22 and power is not acted to latch hook 11, latch hook 11 is under the active force of back-moving spring 12
Reset, the end 111 of latch hook 11 is connected in lock hook slot 132, limits the rotation of cam 13, therefore cam 13 can not trigger every
From lock protective device 5, ensure the door-plate can not be bypassed under door opening state, avoid door caused by maloperation or other reasonses
The situation that plate can not close, the potential safety hazard of enabling sport car is prevented.
Those of ordinary skill in the art it should be appreciated that the embodiment of the above be intended merely to explanation the present invention,
And be not used as limitation of the invention, as long as in the spirit of the present invention, the change to embodiment described above
Change, modification will all fall in the range of claims of the present invention.
