Description

Lock core rotates the ball lock head that non-matching key can not be opened arbitrarily
Technical field
The utility model is the tapered end that a kind of anti-violence of defeating a force with a tenderness is turned round by force, and promptly any instrument can both make lock core rotate the ball lock head that non-matching key can not be opened arbitrarily.
Background technology
The most ball lock heads that occur on the market are all unblanked by the direct rotary locking cylinder of matched key now.The shortcoming of this tapered end is that technology unlocking is easy.In recent years market occurred some novel structures, inventive concept be ingenuity original, the technology unlocking ball lock head of difficulty relatively really, but unsatisfactory aspect turning round by force in uprising power.In all kinds of stolen case in recent years, the violence of simple and fast is turned on lock by force and has been accounted for very big ratio, therefore, a kind ofly can resist violence and turns round by force and prevent that as far as possible the high-performance anti-theft lock end of technology unlocking from being that people expect.
The utility model content
The utility model is mainly formed by keeping off, stay a spoon nail, the ball that puts in place, spring, location ball etc. in lock core, lock tube, rotor, transmission tongue piece, the lock core.Lock core then mainly is made up of lock gall, courage cover, longitudinal spring, pellet shot from a slingshot group, marble spring etc.
The lock gall inner end of lock core is provided with plug tenon; Courage cover outer end is provided with the courage lid, and the courage lid is provided with corresponding keyhole with lock gall; Be provided with a vertical hole of not wearing the end from the inside to surface between lock gall and the courage cover; The pellet shot from a slingshot hole that lock gall and courage cover are laterally established the respective row number according to the section configuration of keyhole; The spoon that stays that little outer hole, hole was big in the courage cover radially was provided with is followed closely the hole; Lock gall is provided with a nail hole corresponding to the spoon nail hole of staying of courage cover, then is provided with one at nail hole outer and stays spoon nail hole.Lock gall places in the courage cover, behind the built-in successively vertical pellet shot from a slingshot in vertical hole between lock gall and the courage cover, the longitudinal spring, with pin cross courage cover inner end with the longitudinal spring shutoff in vertical hole, make outside thrust of lock gall acquisition; The stifled at last upper spring envelope of the built-in successively pellet shot from a slingshot group in pellet shot from a slingshot hole, marble spring promptly becomes lock core of the present utility model.The structure of this lock core resembles ball lock head very much, but the effect of their pellet shot from a slingshot group has tangible difference.Its difference is that the pellet shot from a slingshot group of ball lock head is not produce the relative locking purpose that rotates to be with lock core and lock tube, and promptly non-matching key can not make that lock core is relative with lock tube to be rotated, in case rotation can be unblanked or locking relatively; And the pellet shot from a slingshot group of lock core of the present utility model is that not produce vertical dislocation with lock gall and courage cover be the locking purpose, but matched key can make lock gall and the vertically dislocation of courage cover, is about to lock gall advance inward, and can not make lock gall and courage overlap relative rotation.
Lock tube radially is provided with the ball hole that puts in place corresponding to the spoon nail hole of staying that courage puts.The mortise that vertically being provided with of rotor can allow the plug tenon of lock gall inner end free in and out radially is provided with the ball locating hole corresponding to the hole that puts in place of the ball on the lock tube.The transmission tongue piece is connected with the inner end of rotor.Be blocked in the lock tube inner end in the lock core, be provided with rotor hole in the middle of the retaining in the lock core, radially be provided with the location ball hole corresponding to the hole that puts in place of the ball on epitrochanterian ball locating hole and the lock tube.Stay the spoon nail to be the flat head rivet shape.The courage of lock core puts stays the built-in successively spring in spoon nail hole, stay behind spoon nail, the ball that puts in place the lock core longitudinal register in lock tube; In the rotor hole that the rotor longitudinal register keeps off in lock core, stifled upper spring envelope has just realized the utility model behind location ball hole built-in location ball that keeps off in the lock core and the spring.
Under the utility model normality, the plug tenon of lock gall inner end and epitrochanterian mortise are in released state, have only matched key that their are connected, and also have only this moment rotary locking cylinder just can unblank or locking.When any object of the key that does not match or other inserts keyhole, pellet shot from a slingshot group in the lock core is not put in place by the top, plug tenon can not insert mortise, though this moment, lock core can rotate just idle running arbitrarily, therefore the utlity model has the function that the anti-violence of defeating a force with a tenderness is turned round by force.For traditional cylinder lock, the modal method of technology unlocking is to make the axial freedom of low-angle of institute's core and the relative rotation of overlap with restriction pellet shot from a slingshot group with instrument, insert in keyhole with another instrument then and fiddle with the pellet shot from a slingshot of appearing, it is rotatable and reach the purpose of unblanking all fiddling with the rear lock core that puts in place when the pellet shot from a slingshot group.And the lock gall of lock core of the present utility model and courage to be enclosed within the lock tube be synchronous rotation, the axial freedom that limits the pellet shot from a slingshot group is the top lock gall inward, because of the utility model is provided with the courage lid, the top lock gall can only just can apply top power with disclosing bar insertion keyhole inward, this discloses the then instrument running of fiddling with the pellet shot from a slingshot of appearing of overslaugh greatly of bar, so technology unlocking will be very difficult.
Below in conjunction with accompanying drawing the utility model is further described.
