Abstract

The invention relates to an unlocking device for a vehicle door in a traffic field. The unlocking device consists of latch hooks and a locking plate, wherein the rotation or movement of the latch hooks is limited by meshing between the latch hooks and the locking plate; the blocking of a door leaf is released by the rotation or movement of the latch hooks, so that the locking or unlocking of a door system is realized. The unlocking device for the vehicle door in the traffic field has the advantages that the structure is simple, the releasing force is small, and the manufacturing cost is low.

Description

The tripper of field of traffic vehicle doorn

Technical field

What the present invention relates to is a kind of tripper for field of traffic vehicle list fan or double door, belongs to door system locking device technical field.

Background technology

Adopt at present the door system of the driving mechanism of spindle drive, there are locking and release problem always, various brakes commonly used or the locking that is locked into capable door system and the release that by electromagnetism, hydraulic pressure, the mode such as pneumatic, are driven, its release often needs other power source.This causes whole mechanism complexity, and expense is high, poor reliability.

Some passive locking devices of current technical existence, be all the rotating drive main shaft basically during release, because driving shaft is connected with motor, during rotation, need overcome larger power.

Summary of the invention

Goal of the invention: the purpose of this invention is to provide a kind of simple in structurely, operating physical force is little, failure rate is low locking system tripper.

Technical scheme: the present invention adopts following technical scheme to be realized:

A kind of tripper of field of traffic vehicle doorn, comprise latch hook, roller, lockplate, base plate, roller is arranged on door leaf, lockplate and latch hook are arranged on base plate and can freely rotate on base plate by axle, protuberance is set on lockplate, and an end of latch hook arranges shrinkage pool, and the other end arranges hook, in the closed position when upper when door, hook hooks roller and shrinkage pool embeds in the protuberance arranged on lockplate.

On the axle of lockplate and latch hook, torsion spring is set.

Also comprise alignment pin, an end of described alignment pin is fixedly installed on base plate, and the other end is arranged in the deep-slotted chip breaker arranged on latch hook.

Also comprise trigger switch, described trigger switch is fixedly installed on base plate, and when door is closed, trigger switch contacts with lockplate.

Beneficial effect: compared with prior art, its roller opposite house that utilizes latch hook to hook and arrange on door leaf is fixed in the present invention, and it is simple in structure, and releasing force is little, successful, and utilize lockplate to carry out further locking to latch hook, make the system safety and reliability.

The accompanying drawing explanation

Fig. 1 is the structural representation of apparatus of the present invention;

Fig. 2 is exploded perspective view of the present invention.

The specific embodiment

Below in conjunction with Figure of description, the present invention is described in further detail:

The present invention relates to a kind of tripper of field of traffic vehicle doorn, comprise latch hook 5, roller 3, lockplate 7, base plate 13, roller 3 is arranged on door leaf, lockplate 7 and latch hook 5 are arranged on base plate 13 by rotating shaft and both all can freely rotate on base plate, on lockplate 7, protuberance is set, latch hook 5 is L-type, the one end arranges shrinkage pool, the other end arranges hook, when door in the closed position when upper, hook hooks roller 3 and shrinkage pool embeds in the protuberance arranged on lockplate 7, reaches the sufficient effect of locking.

In the present invention, on the axle of lockplate 7 and latch hook 5, torsion spring is set, lockplate 7 and latch hook 5 can be got back on initial position when losing its active force like this.

Tripper of the present invention also comprises alignment pin 8, described alignment pin 8 is fixedly installed on base plate 13, be provided with the groove of one arc on latch hook 5, alignment pin 8 just is arranged in groove, the purpose that alignment pin is set is to limit the angle that latch hook 5 rotates, and makes it to be unlikely to rotate the excessive normally locking of door that causes.

Tripper of the present invention also comprises trigger switch 12, and described trigger switch is fixedly installed on base plate 13, and when door is closed, trigger switch 12 contacts with lockplate 7, and then trigger switch sends the locking signal that puts in place.

Below with a concrete example, the present invention is described:

While opening the door release, twist-lock plate 7, make lockplate 7 break away from engagement with latch hook 5, with the connected roller 3 of door leaf, under the effect of adhesive tape bounce, pushes latch hook 5 open, realizes opening the door.After roller 3 leaves latch hook 5 positions, latch hook 5 is returned to locked position under the torsion spring active force, now, then unclamps lockplate 7, and lockplate 7 again recovers engagement with latch hook 5 under torsion spring 9 active forces.

At closing time, twist-lock plate 7, make lockplate 7 break away from engagement with latch hook 5, then the roller on door leaf 3 hits in the hook of latch hook 5, and hook hooks roller 3, now unclamps lockplate 7 again, lockplate 7 again recovers engagement with latch hook 5 under torsion spring 9 active forces, realizes complete locking.

This device can also have different concrete forms of implementation, the structure shown in not necessarily must adopting.Such as latch hook 5 and lockplate 7 can be movable type.This kind of device also can be used on single door.
