Technical field

The utility model relates to a kind of appurtenances of motor vehicle, especially the door lock of motor bike, tricycle or car.

Background technology

The car door of motor vehicle needs that all lockset is installed and fixes car door, prevents that car door is opened in the process of moving, takes advantage of personnel to leave Che Houneng locking car door at frame in addition, plays antitheft effect.But, motor vehicle lockset of the prior art, be called the disclosed automobile-use lock of utility model patent that " automobile-use safety door latch ", the patent No. are ZL03210880.X as name, and another name is called " light tricycle door lock ", the patent No. is the automobile-used lock of the disclosed motor tricycles of utility model patent of ZL01274700, its structure is more complicated all, with lockset open, all not too convenient during closed door, flexibly; With the key turns dead bolt time, because will driving eccentric block, dead bolt produces the eccentric type rotation, cause phenomenons such as its bumpy motion, existence are stuck, do not open, not too convenient when the user uses, when being stuck, dead bolt allow the people very irritated, feel very much helpless.

Summary of the invention

The utility model provides a kind of motor vehicle door lock simple in structure, flexible and convenient to use at the above-mentioned deficiency of prior art.

The technical solution of the utility model: motor vehicle door lock, comprise lock body, keyhole, lock core and the handle that opens the door, the handle that opens the door is movably arranged on the lock body; It is characterized in that: on the handle pivoted arm of handle that opens the door, be provided with the locking mouth; The tail end of lock body is connected with eccentric block, can drive eccentric block and rotate synchronously; Eccentric block is connected with an end of latch, and the other end of latch can stretch in the locking mouth, stops the handle pivoted arm to rotate;

Further feature is: the end face of described eccentric block directly and an end in contact of latch; Return spring is set on latch;

The contacted side of latch and eccentric block is a curved surface.

Motor vehicle door lock of the present utility model with respect to prior art, has following characteristics:

1, simple in structure; On original structure, do less change, just can play the effect that prevents that car door is opened in the process of moving, take advantage of personnel to leave Che Houneng locking car door, play antitheft effect at frame.

2, flexible and convenient to use; Use the key of adapted, just can be easy to open or closed door.

3, can effectively reduce the cost of door lock, strengthen its market competitiveness.

Description of drawings

Below in conjunction with accompanying drawing the utility model is further described:

Fig. 1 is the utility model structural front view;

Fig. 2 is the rear elevation of Fig. 1;

Fig. 3 is second kind of example structure figure of the utility model.

The specific embodiment

In Fig. 1,2,1-lock body, 2-keyhole, 3-lock core, the 4-handle that opens the door, the 5-pivoted arm of shaking hands, 6-connects a piece, and 7-connects cross bar, 8-torsion spring, 9-pull bar, 10-locking mouth, 11-eccentric block, 12-latch, 15-curved surface, 16-return spring;

Motor vehicle door lock of the present utility model comprises lock body 1, keyhole 2, lock core 3 and the handle 4 that opens the door, and lock body 1 is provided with keyhole 2, lock core 3 is arranged in the keyhole 2, lock core 3 is the lock cores that can match with key, and during key, lock core 3 produces corresponding rotational action.Be movably set with the handle 4 that opens the door on lock body 1, the handle 4 that opens the door is connected on the lock body 1 turnably with handle pivoted arm 5.The movable connection method of open the door handle 4 and the lock body 1 shown in the figure, be on lock body 1, to be provided with two to connect a piece 6, prop up a piece 6 and couple together with being connected with connecting cross bar 7 pivoted arm 5 of will shake hands, connect the torsion spring 8 that cross bar 7 is provided with the return effect, handle pivoted arm 5 is connected with an end of pull bar 9, the other end of pull bar 9 is connected with Door-lock bolt body (not shown), can drive the Door-lock bolt body by pull bar 9 when the handle 4 that opens the door is rotated and produce the effect that opens or closes accordingly; When opening the door, firmly pulling is opened the door and is shaken hands 4, and the handle pivoted arm 5 of the handle 4 that opens the door rotates around connecting cross bar 7, and the pull bar 9 that the while is connected with handle pivoted arm 5 drives the Door-lock bolt that is connected with pull bar 9 and produces corresponding actions, opens door lock.

On handle pivoted arm 5, be provided with locking mouth 10, specifically locking mouth 10 can be designed to form of grooves; The tail end of lock core 3 is connected with eccentric block 11, can drive eccentric block 11 and rotate synchronously; Eccentric block 11 is connected with an end of latch 12, and the other end of latch 12 can stretch in the locking mouth 10, stops handle pivoted arm 5 to rotate.That is, when needs are locked a door, with the key rotation lock core 3 (generally being to rotate half-turn) of adapted, lock core 3 drives eccentric block 11 and rotates, eccentric block 11 drives latch 12 again and moves forward, and latch 12 is stretched in the locking mouth 10, and latch 12 just can stop handle pivoted arm 5 to rotate; Open the door handle 4 o'clock of pulling firmly externally, because handle pivoted arm 5 is spacing and can not rotate by latch 12,4 rotations of shaking hands that just limit opens the door just can not be opened car door.

In Fig. 3, because eccentric block 11 produces certain offset when rotating, be that eccentric type rotates, make the bumpy motion of latch 12, be easy to generate phenomenon such as be stuck, do not open, as further improvement of the utility model, the end face of eccentric block 11 directly with an end in contact of latch 12, be curved surface 15 with latch 12 and eccentric block 11 contacted lateral layout; When eccentric block 11 rotated, the eccentric distance of eccentric block 11 can drive latch 12 and move forward, and latch 12 is stretched in the locking mouth 10; Curved surface 15 to the impact force of latch 12, steadily moves latch 12 when effectively buffering eccentric piece 11 rotates.Simultaneously,, return spring 16 (when needed) can be set on latch 12, help its return, when eccentric block 11 backward rotation, can help latch 12 in locking mouth 10, to withdraw from, be returned to open position according to actual conditions.The lockset that is provided with for vertical direction generally can both self-return, can not need return spring 16, and the lockset of settling for horizontal direction, can not self-return, return spring 16 its returns of help just need be set in addition.
