Abstract
The invention relates to an anti-prizing separating structure used for a lock, which consists of a lock head, a driving gear, a driven gear and a part used for fixing the lock head. An elastic part is arranged between the lock head and the part used for fixing the lock head. When in normal use, a lock body is comparatively fixed in virtue of the elastic part; when a lock cylinder is twisted by an abnormal torque, the lock cylinder drives the lock body to turn and also drives the meshed driving and driven gears to be separated, so as to lead the torque brought to the clock cylinder for separating to fail. The invention has the advantages of simple structure, easy and simple manufacture, low cost. The lock heads installed on various bins, cases and automobiles, etc. objects all can adopt the structure of the invention, so the invention is provided with a wide application scope and a strong practicality.
Description
Technical field
The structure that the present invention relates to lock particularly relates to the pick-proof lock that can separate torsion idle running.
Background technology
At present existing disclosed all separate type theftproof locks, its separated structures all be arranged in the lock body or lock core in, though such design can reach pick-proof, anti-technology unlocking even anti-drilling purpose, but these project organization complexity, cause the increase of difficulty in the manufacture process, manufacturing cost also can increase thereupon.Present robber's most means that adopt sled of unblanking to commit a crime, the means that operation technique is unblanked and electric drill is unblanked are also few, though therefore above-mentioned technology can prevent that lock from illegally being opened because the real utilization of lock of reason such as cost so that this structure and few.But because at present a large amount of lock that uses does not have the separation lost motion functionality, this lockset robber is easy to use special screwdriver that it is pried open again, just is easy to be pried open by the robber such as the electric door lock of back-up case lock, motorcycle and the electric motor car of some cars etc.
Summary of the invention
For a change above-mentioned this situation, it is not high to the invention provides two kinds of costs, simple and practical, can reach the technical scheme that prevents the pick-proof lock that can separate torsion idle running pried open by the robber again, the common trait of two kinds of technical schemes is, all be to utilize at lock body and fixedly between the object of lock body elastic resistance is set to come the position of rotation of lock body is carried out relative fixed, under normal circumstances lock body is owing to the resistance that is subjected to the elasticity thing can not rotate, and lock core can not rotate relative to lock body when lock core is subjected to the torsion of illegal rotation, and lock core can drive the lock body rotation, the feasible master who transmits torsion, driven gear is separated, and separates and the purpose of idle running thereby reach lock core torsion.
The technical solution adopted in the present invention one is:
A kind of pick-proof separating structure of lock, comprise tapered end and gear, described tapered end is columniform tapered end, comprise lock body and lock core, described lock body is provided with the lock body shoulder, and described gear comprises driving gear and driven gear, it is characterized in that: total also comprises the support that is used for fixing tapered end and gear is installed, described support both sides respectively are provided with a tooth axis hole, and wherein a side also is provided with a lock body opening; Tapered end installation rear locking shoulder is exposed to lock body opening and is arranged in lockhole outward, and the lock body in the support is provided with compression spring and nut, also is provided with the notched separation of thereupon rotating on the lock body and dials circle, and lock core pole is provided with the driving gear that thereupon changes together; Also be provided with gear shaft on the support, gear shaft is provided with can axially movable separation collar, with gear shaft with change and can axially movable driven gear, return spring and jump ring, driving lever can be fixedlyed connected with gear shaft or gear; Also be provided with the screw hole that is used for fixing support on the support; After all part installed, driven gear was meshed with driving gear, separated collar and just in time was in the separation group breach that encloses, and adjusted the degree of tightness of nut, made and compressed the resistance that spring stops the lock body rotation, must stop the resistance of lock body rotation less than lock core marble.
In order to make the dead bolt self-return, gear shaft is provided with torsion spring.
When legal key is unblanked, lose the barrier force of lock core marble between lock core and the lock body, the driving gear on the lock core pole drives driven gear and rotates, and rotates thereby drive driving lever; When illegal rotational lock core, because lock core marble stops the resistance of the resistance of lock body rotation greater than the rotation of the prevention lock body that spring produced between support and the lock body (nut), lock body is followed lock core and is rotated, separate to dial to enclose and also follow the lock body rotation and produce a thrust separating collar, separate collar this moment and move axially and promote driven gear and axially move, make driven gear separate with the driving gear of engagement.
The technical solution adopted in the present invention two is:
A kind of pick-proof separating structure of lock comprises tapered end, gear, and described tapered end is columniform eccentric tapered end, comprise lock body and lock core, described lock body is provided with lock body shoulder, and described gear comprises driving gear and driven gear, and total also comprises the fixedly lockhole of tapered end and the support of installation lock shaft; After total installed, the lock body shoulder was exposed to outside the lockhole; On the lock body of lockhole inboard nut is set, is provided with elastic washer and ring washer between nut and the lockhole wall, appear to be installed with thereupon on the lock core pole of lock body and fix with the driving gear jump ring that changes; Fixedly install support on the lockhole wall of lock core eccentric direction, driven gear shaft is installed on the support, the driven gear that thereupon changes together is installed on the gear shaft, and be meshed with driving gear; Sword iron is connected with the tooth axle; After tapered end installs, adjust the degree of tightness of nut, make elastic washer stop the resistance that lock body rotates, must stop the resistance that lock body rotates less than lock core marble.
In order to make the dead bolt self-return, gear shaft is provided with torsion spring.
When legal key is unblanked, lose the barrier force of lock core marble between lock core and the lock body, the driving gear on the lock core pole drives driven gear and rotates, and rotates thereby drive sword iron; When illegal rotational lock core, because lock core marble stops the resistance of the resistance of lock body rotation greater than the rotation of the prevention lock body that spring produced between lockhole wall and the lock body (nut), lock body is followed lock core and is rotated, because lock core and lock body disalignment, lock body must move once the rotational lock core location in space, main at this moment, driven gear natural separation.
Compare with modern technologies, biggest advantage of the present invention is: simple in structure, with low cost, manufacturing is easy, pick-proof is effective, the tapered end of being installed on most of objects such as various bins, lock box, automobile, furniture all can adopt structure of the present invention, and is of many uses, practical.
