Abstract
The utility model relates to a combined cipher lock. The utility model is characterized in that a lock core is arranged on the center of a cipher disc and is fixed by a spring and a cylinder. The rear part of the lock core is provided with a clamping spring which is used for fixing the lock core and the cipher disc together. A lock sleeve is sheathed on the cipher disc, and the lock sleeve and the cipher disc are fixed together by the clamping spring. The rear part of the cipher disc is provided with a driving blade in a matching way, the front part or the rear part of the driving blade is provided with a driven blade, the driving blade and the driven blade matches with each other in a disc cover for blades by the isolation of gaps by the clamping spring, and the driving blade and the driven blade can be rotated. The exterior of the disc cover for blades is provided with a bracket and is provided with an open slot in the axial direction. The cipher disc can be rotated only by inserting a key in the cipher disc, and the lock core can be rotated by the key after the blades and the open slot of the disc cover for blades are aligned with each other. The utility model has the advantages of large unlocking assurance coefficient and large volume. The utility model can be used in safety cabinets and anti-theft doors.
Description
The utility model relates to coded lock, is the combination pin lock that a kind of safety cabinet and security door use.
At present, the puzzle lock that circulates on the market mostly is made up of lock cylinder, blade password and three independent sectors of switch knob, the organic interlocking deficiency of this lock, the assembling area is big, and small-sized safety cabinet is all had certain difficulty from office of portion to installing, the blade password of this lock is installed on the combination disk axle, little with the contact area of axle, easily generation radially wobbles, and causes the password precision low, even cause password to misplace the coded lock problem of not opening.
The purpose of this utility model provides a kind of combination pin lock, big to solve existing password lock assembling area, organic interlocking deficiency, small-sized safety cabinet all there is certain difficulty from office of portion to installing, and blade and be coupling that to touch area little, easily produce to radially wobble, cause the password precision low, cause the password dislocation, the coded lock problem of not opening.
The purpose of this utility model is achieved in that this lock is by lock core, key, combination disk, blade, connecting rod, cottor pin, pad is formed, lock cylinder is installed in the combination disk center, by spring, pellet shot from a slingshot is fixed, the lock core rear portion is provided with jump ring, lock core and combination disk are fixed together, after key inserted, combination disk just can be rotated around lock core, is with lock tube outside combination disk, by jump ring lock tube and combination disk are fixed together, the combination disk rear portion is combined with active blade, is provided with passive blade before or after the active blade, and active blade and passive blade are engaged in the fan disk cover by the jump ring external series gap, can in the fan disk cover, rotate, the fan disk cover is axially arranged with open slot, and external surface is provided with support, when the blade openings groove with after fan disk cover open slot aligns, the key band lock core and could be rotated, and the lock core end is connected with connecting rod by bearing pin.
This utility model compared with prior art has the following advantages: 1) lock core, combination disk and handle three are integrated, volume is small and exquisite, and compact conformation is convenient to install and use on safety cabinet and the security door; 2) blade external diameter location under the situation that does not increase volume, has guaranteed the smooth rotation of blade effectively, has overcome easy generation of blade and has radially wobbled, and causes password dislocation, the coded lock phenomenon of not opening; 3) increase the mutual restriction function, must insert key ability rotational password dish, increased the safety factor of unblanking.
Be described further below in conjunction with accompanying drawing:
