Description

The safety vehicle door lock

Technical field

The utility model relates to a kind of automobile door lock, and particularly a kind of closing of the door of can working as is in when locking the position, can not open the safety vehicle door lock of car door in the car.

Background technology

Now the automobile door lock of Shi Yonging does not have tapered end (to lock) mechanism safely, pushes lockset position of coupler when the stranger utilizes the car door gap will lock carrying handle or triangle fork, and car door will be opened naturally, and is very dangerous.

Summary of the invention

The purpose of this utility model just provides a kind of closing of the door of can working as and is in when locking the position, and the outer people of Che Nei and car can not open the safety vehicle door lock of car door.

The technical solution of the utility model is: the tapered end to existing car door lock improves, and with one group of reed trough in the original lock body of this tapered end, increases to two groups, two groups of interval certain angles, general 90 ° of angles at interval.Be equivalent to increase by one like this and lock the position, this position will be mentioned the position of the upper limit with an end of triangle fork on the lock body that its lock core is connected, and with car that this triangle fork other end is connected in handle, Internal handle door-opening mechanism and outer handle door-opening mechanism all be in by triangle and pitch the state of straining, Suo Ding state just, no matter be to open the door by handle, Internal handle door-opening mechanism and outer handle door-opening mechanism in the car this moment, still stirs the triangle fork and all can not reach the purpose of opening the door.And when lock core is in original normal condition, can in car, mention handle to open car door, do not influence the normal function of use of car door.

The utility model has the advantages that: the driver places the state of locking at car external application key with lock after stopping, and all can not arbitrarily open car door from driver's cabin is inside and outside, and it is simple in structure, easy to use, has played safety effect.

The specific embodiment

Below in conjunction with drawings and Examples the utility model is further specified:

Referring to Fig. 1～Fig. 4, overall formation of the present utility model is same as the prior art, comprise lock body 11, tapered end 3, pull bar 5, group plate 4, handle 8, triangle fork 7 and key 1, there is the connector that can rotate with lock core that is connected with lock core on the top of tapered end 3, this connector is connected with an end of dialling plate 4, dialling the other end of plate 4 and the upper end of pull bar 5 is hinged, the lower end of pull bar 5 is connected with an end of triangle fork 7, the middle part of triangle fork 7 pass in the lock body 11 and with its hinge, the lower end hinge of the other end of triangle fork 7 and handle 8.Tapered end 3 of the present utility model is when being in normal condition, identical with existing car door lock, be dialling plate 4 and can in certain angle, freely swing among Fig. 4, the right-hand member of triangle fork 7 can be swung up and down, its left end also just can move up and down, like this by the lock door mechanism in the lock bodies of triangle fork 7 controls, handle 8 mention or by Internal handle door-opening mechanism 9 with outside handle door-opening mechanism 10 all can be with car door opening.

Referring to Fig. 5 and Fig. 6, this is tapered end 3 internal construction schematic diagrames of the present utility model, be that the tapered end that has car door lock now is improved, with one group of reed trough 32 in the original tapered end 31 of this tapered end, increase to two groups, two groups of interval certain angles, this embodiment is 90 ° of angles at interval, and the structure of lock core 33 is constant.Fig. 5 is that lock core 33 is not in the structure of (normal condition of prior art) when locking state, and Fig. 6 is that lock core 33 is being locked the structure of state.Be equivalent to increase by one like this and lock the position, group plate 4 that this position will be connected with its lock core 33 swings to the B position among Fig. 4, dial plate 4 and be locked in this position by lock core this moment, it can not be to swing counterclockwise, dial plate 4 and the right-hand member of triangle fork 7 is upwards mentioned the upper limit position position by pull bar 5, and with car that the other end of this triangle fork 7 is connected in handle 8, Internal handle door-opening mechanism 9 and outer handle door-opening mechanism 10 all are in by the state of triangle fork 7 tensions, Suo Ding state just, no matter be by handle in the car 8 this moment, Internal handle door-opening mechanism 9 and outer handle door-opening mechanism 10 open the door, and still stir triangle fork 7 and all can not reach the purpose of opening the door.

(when key 1 insertion tapered end 3, key 1 is in Fig. 5 state.Clockwise 70 ° are in the enable possition, and carrying handle 8 is upspring, and external handlebar 10, interior handgrip 9 lift and can open the door, and lock body 11 breaks away from snap close 6.

Referring to Fig. 1～Fig. 4, Fig. 6, when car door is in closed condition, key 1 inserts tapered end 3,1 inverse time of key rotates 90 ° and extracts, and lock core 33, group plate 4 are in the state of locking among Fig. 6, and handle 8 falls, move on pull bar 5, the triangle fork 7, handle 8 firmly can not be mentioned, and external handlebar 10, interior handgrip 9 lift and belong to the room, can not open the door.) can (annotate: the content in the above parantheses be deleted?)

Claims (2)

1, a kind of safety vehicle door lock, the tapered end of this door lock is made up of tapered end and the lock core that is positioned at it, is provided with reed on lock core, is provided with the reed trough corresponding with described reed in the lock body inboard, it is characterized in that: described reed trough is provided with two groups, two groups of interval certain angles.

2, safety vehicle door lock according to claim 1 is characterized in that: 90 ° at interval of described two groups of reed troughs.
