Description

A kind of mechanical delay theftproof lock

Technical field

The present invention relates to a kind of lockset, particularly a kind of mechanical delay theftproof lock.

Background technology

Cylinder lock is a kind of lockset of extensive use, and its structure comprises lock body, sheath, lock core, pellet shot from a slingshot and spring; Its principle is to use the pellet shot from a slingshot of a plurality of differing heights to pin lock core, and when in keyhole, inserting key, tooth on the key can be pushed to identical height with each pellet shot from a slingshot, and lock core is just decontroled, and the twisting key makes the lock core rotation, realizes unblanking; Because its principle of unblanking is simple; Do not having under the situation of key; Multiple method of unblanking is also arranged; The craftsman that under the less situation of marble amount, unblanks only needs safety pin safe in utilization that pellet shot from a slingshot top to same height can be opened, even when marble amount is more, a kind of master key of circulation also can be opened within a certain period of time easily in the market; So the antitheft of cylinder lock becomes the difficult problem that the lockset industry is badly in need of solution.

Summary of the invention

Technical problem to be solved by this invention provides a kind of mechanical delay theftproof lock, can effectively improve the cylinder lock security performance.

For solving the problems of the technologies described above, the technical scheme that the present invention adopts is: a kind of mechanical delay theftproof lock, comprise that sheath, middle part are provided with the lock core of cross keyhole and are located at the terminal jump ring of lock core; Its key improvements is: also comprise dead bolt, keyhole locking device, mechanical delay mechanism and the corresponding terminal lock core locking mechanism that is used for secondary locking lock core of lock core of being located at; Said dead bolt is installed in the lock core end by means of jump ring; The dead bolt bottom is provided with the open long slot bore of an end;

Said keyhole locking device comprises the discoid following clamp of going up clamp, being located at dead bolt bottom and dead bolt matched in clearance that is fixed at dead bolt top, be located at down that between clamp and the last clamp helical spring to be set and to be located in the interior cross section of keyhole be criss-cross push rod; Said push rod upper end is fixedly connected with said clamp down; Said down clamp lateral surface be provided with one circle shape groove and with the supporting rotating ring that is provided with of groove;

Mechanism was located on sheath and the terminal corresponding end face of lock core and was positioned at said jump ring opening one side said mechanical delay; Mechanism comprised " U " font support, the axis of rotation that laterally is arranged in " U " font support top that are fixed on the sheath end face, was fixed at the ratchet mechanism that tooth rest, time-delay gear train and symmetry on the axis of rotation is fixedly arranged on the tooth rest both sides said mechanical delay; Said tooth rest both sides also are arranged with two second pull bars, second pull bar, one end and axis of rotation matched in clearance, and an other end and said rotating ring are hinged; Between said tooth rest and " U " font support reduction torsion spring is set; Said ratchet mechanism comprises that symmetry is fixed at the ratchet ratchet inboard with being located at second pull bar on the tooth rest two sides;

Said lock core locking mechanism and mechanical delay mechanism be symmetrical set with respect to dead bolt; Said lock core locking mechanism comprise the base that is fixed on the terminal corresponding end face of sheath and lock core, with base top surface on the slide block that is equipped with of the dovetail shaped slideway that is provided with; Said slide block bilateral symmetry is hinged with two first pull bars, and an other end of two first pull bars is hinged on said tooth rest two side bottoms respectively.

Said time-delay gear train comprises and is fixed at the tooth rest inner fixed axis, first gear, second gear, the 3rd gear, one-way wheel and the vibrating wheels that laterally arrange with axis of rotation; Said the 3rd gear is fixedly connected with axis of rotation; Said second gear and vibrating wheels are located on the axis of rotation by means of bearing; Said first gear and one-way wheel all are located on the fixed axis by means of bearing; Said first gear is a secondary gear, its pinion and the 3rd gears engaged; Said second gear also is a secondary gear, the gear wheel engagement of its pinion and first gear; Said one-way wheel right side is fixed with the pinion with second gears engaged; The immersion needle engagement on said one-way wheel and vibrating wheels right side.

Said sheath is provided with elastic collet, the corresponding setting with vibrating wheels of said elastic collet with the terminal corresponding end face of lock core.

Adopt the beneficial effect that technique scheme produced to be: the keyhole locking device is set in keyhole, and when cylinder lock was in locking states, push rod filled up keyhole, prevented that foreign matter from getting into keyhole and influencing the normal use of cylinder lock; The sheath end face be provided with respectively with keyhole locking device interlock mechanical delay mechanism with the lock core locking mechanism, when inserting correct key, it is mobile backward that key promotes push rod; Mechanical delay, mechanism's integral body rotated around axis of rotation; Realize that through promoting second pull bar slide block outwards slides in the rotary course, thereby remove the restriction of slide block to the lock core rotation, this moment, screw key can be realized unblanking; In screw key; Be fixedly mounted on jump ring aperture position on the lock core home position of staggering, and then make elastic collet withstand vibrating wheels, stop mechanical delay mechanism to reset; When the key that inserts not is the key of this lock correspondence, even master key also needs the regular hour could pellet shot from a slingshot be pushed up equal height, but after push rod is headed into keyhole; Mechanical delay, mechanism just can reset under the effect of reduction torsion spring gradually; Simultaneously, block lock core after the slide block in the lock core locking mechanism resets, promptly enable pellet shot from a slingshot is pushed up to equal height; Can not rotary locking cylinder, play the effect of antitheft; In addition on the one hand; If insert the key of keyhole is not the corresponding key of this lock; Push rod can not withdraw from along with extracting of key when extracting key; And the lock core locking mechanism is in locking states always, has only to insert with correct key and could unblank again after keyhole resets push rod, improves the security performance of cylinder lock greatly.
