Abstract
The utility model discloses a door lock turning assembly which comprises a turning body, an outer turning body, and an inner turning body. The outer turning body and the inner turning body are arranged in the turning body. A notch is formed in the turning body, a hinge is arranged at the notch of the turning body, and the hinge is fixed on the turning body through a pin. The outer turning body is provided with a protruding portion, the protruding portion is staggered with the hinge, due to the fact that the hinge is attached to the inner side of the turning body, when the outer turning body rotates in the reverse direction of the unlocking angle, a limiting effect is achieved, and when the outer turning body rotates in the direction of the unlocking angle, the hinge bounces off under the action of the protruding portion of the outer turning body and resets through a torsion spring, and no matter how the outer turning body rotates in the direction of the unlocking angle, a door lock can not be unlocked.
Description
Technical field
The utility model relates to turning in a kind of door lock, relates in particular to a kind of door lock assembly of turning.
Background technology
Door lock on present market, on turning, be provided with a limiting component, this limiting component is to rotate by the opposite angles of unblanking in order to limit external rotary member, existence due to this limiting component, when external rotary member surpasses certain angle by the angle rotation of unblanking, by this limiting component, can open door lock, and without from pin, this brings hidden danger to safety, in order to address this problem, door lock on the market often arranges another limiting component in door lock shell, this limiting component is in order to prevent that external rotary member from surpassing certain angle by the angle rotation of unblanking, for example external rotary member is limited in the 50 degree anglecs of rotation by the direction of unblanking, but when in use, if when firmly external rotary member being surpassed to 50 degree by the angle rotation of unblanking, the limiting component that is arranged on door lock shell is damaged, thereby make external rotary member angle limits without spin, door lock will destructively be opened in this case, caused safety greatly to reduce.
Utility model content
For above-mentioned technological deficiency, the utility model proposes a kind of door lock assembly of turning.
In order to solve the problems of the technologies described above, the technical solution of the utility model is as follows:
A kind of door lock assembly of turning, comprise and turn and be located at turn inner external rotary member and inner rotary member, described turning is provided with breach, in described indentation, there of turning, be provided with a hinge, on turning described in described hinge is fixed by a pin to, described external rotary member is provided with jut, and described jut becomes to interlock with described hinge-shaped.
Further, described hinge and described in be provided with elastomeric element between turning.
Further, described hinge is near a side of the described breach of turning.
Further, described elastomeric element is torsion spring.
Further, described hinge is provided with breach, described hinge breach size and the breach inner side of turning match and be close to described in the breach inner side of turning, a side and the described jut of described hinge breach form staggered.
The beneficial effects of the utility model are: by the setting of this hinge, because this hinge is close to the inner side of turning, when external rotary member is when unblanking the counter-rotation of angle, play the effect of restriction, and when external rotary member is when unblanking the direction rotation of angle, this hinge can flick under the effect of external rotary member jut, and utilize torsion spring self-resetting, can opening door lock thereby how no matter external rotary member rotate all not towards the direction of the angle of unblanking, this scheme adopts the limiting component of one-directional rotation, close to have abandoned in prior art and fixing limiting component is set turning, can meet the needs of unblanking, there is the problem that traditional scheme produces that solved, and simple in structure, during damage parts, only hinge or torsion spring need to be replaced, and without whole turning replaced.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the explosive view of hinge of the present utility model;
Fig. 3 is the application drawing of the utility model in door lock.
The specific embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described further.
As shown in FIG. 1 to 3, a kind of door lock assembly of turning, comprise and turn 4 and be located at turn inner external rotary member 7 and inner rotary member 11, described turning 4 is provided with breach 1, at described 4 breach 1 place of turning, be provided with a hinge 3, in the side of 4 breach 1 of turning described in described hinge 3 is fixed on by pin 9, described external rotary member 7 is provided with jut 5, and the hinge 6 of described jut 5 and described hinge 3 forms staggered.Staggered by this, the rotation of jut 5 can drive collaborating of hinge 6, simultaneously described in this hinge 3 and described in turn and between 4, be provided with the elastomeric element for replying, this elastomeric element preferably can adopt torsion spring 2, turn described in described hinge 3 an is adjacent to side of 4 breach 1, this is arranged so that the formation one-directional rotation of hinge 3, when external rotary member is during towards the opposite spin of the angle of unblanking, jut 5 drives hinge 6, and now a turned side of 4 breach 1 of hinge 6 is blocked, therefore this arranges external rotary member 7 rotation formation spacing, and when external rotary member 7 is during towards the direction rotation of the angle of unblanking, due to the opposite side of hinge 6 and by not having any stopping, all can rotation easily, jut 5 drives hinge 6, when surpassing certain angle, 5 of juts streak hinge 6, and hinge 6 reinstatement under the effect of torsion spring 2, thereby external rotary member 7 constantly rotates, but be still with motionless 4 rotations of turning, guaranteed the safety of unblanking, preferably, in the middle of the hinge 6 of described hinge 3, be provided with breach 10, the circular arc of described hinge breach 10 sizes and 4 breach 1 inner side of turning match and be close to described in the turn circular arc of 4 breach 1 inner side, one side and the described jut of described hinge breach 10 form staggered, on original basis, by the circular arc of the breach inner side that breach 10 in hinge 6 can be close to the lower end of hinge 6 to turn is set, thereby between hinge 6 and jut 5, the area of contact is larger, and structure is compacter, compare and do not establish breach, its limit function better effects if.
The above is only preferred embodiment of the present utility model; it should be pointed out that for those skilled in the art, without departing from the concept of the premise utility; can also make some improvements and modifications, these improvements and modifications also should be considered as in the utility model protection domain.
