Description

The steel cable lock of built-in password

Technical field

The utility model relates to a kind of steel cable lock, especially for the steel cable lock of the antitheft built-in password of bicycle, two-wheeled motor vehicle.

Background technology

What the mode of unblanking of existing tapered end was common mainly contains two kinds: coded lock or key lock.Coded lock is unblanked by password character wheel to the correct coding on the rotation tapered end, need not to carry key, and very convenient, secrecy is higher, and safety is better; Key lock generally is that a key is inserted in the lock core, utilizes teeth groove on the key or the convex-concave step on the relative position promotes in the lock core pellet shot from a slingshot or blade moves, make lock core can be under the drive of key the rotation lock lock, thereby lock is opened.This lock is most widely used, uses more safe and reliable.

The known steel cable lock mode of unblanking is fairly simple, general most key unlockings that adopt, and this mode of unblanking has the conveniently advantage of unblanking, still, if forgotten the band key or lose key and just can't unblank.

In addition, existing password is locked in when producing, and for different passwords is set, generally needs to make many different cipher wheel moulds according to different passwords earlier, has increased the production technology and the cost of cipher wheel.

The utility model content

The purpose of this utility model is to overcome the deficiencies in the prior art and a kind of have password and two kinds of modes of unblanking of key is provided, and can guarantee the steel cable lock of the built-in password of reliably unblanking.

Further purpose of the present utility model is to provide a kind of cipher wheel of modularized design manufacturing, and it can form different passwords according to the assembled arrangement of each module diverse location.

In order to realize above purpose, the utility model adopts following technical approach: a kind of steel cable lock of built-in password comprises wirerope, lock body, key lock, coded lock, coded lock comprises coded lock plug, cipher wheel and the lock pipe that is connected as a single entity with lock body that is provided with projection vertically continuously.The fixedly connected key lock tapered end of one end of wirerope, the key lock tapered end is locked with cylinder lock, the fixedly connected coded lock plug of one end of wirerope, cipher wheel is provided with and the corresponding breach of unblanking of coded lock plug projection, the lock pipe is provided with the slit vertically, and the width in described slit and coded lock plug ledge width adapt.

The utility model can further be set to: cipher wheel is made of spacer and digital roller, the numeral roller evenly is provided with the coding breach along its inner periphery, the spacer outer circumference surface is provided with the projection that cooperates with cipher wheel coding breach, the breach of unblanking of cipher wheel is located on the spacer, and spacer and digital roller poststack mutually can be enclosed within lock body lock Guan Shangyu coded lock plug rotationally and form password unlocking and cooperate.

Compared with prior art, the beneficial effects of the utility model are to have password and two kinds of modes of unblanking of key simultaneously, therefore have the advantage of these two kinds of modes of unblanking simultaneously, under the usual condition, open with key, can use password unlocking when losing key.

In addition, the utility model improves the cipher wheel of coded lock, adopts spacer and the chimeric mode of digital roller to form the cipher wheel of different coding, and the production technology of cipher wheel is simplified.

The specific embodiment

The steel cable lock of the built-in password shown in Fig. 1-6 comprises wirerope 2, lock body 1, blade lock, coded lock.Coded lock comprises coded lock plug 6, cipher wheel and the lock pipe 7 that is connected as a single entity with lock body that evenly is provided with projection vertically.The fixedly connected key lock tapered end 10 of one end of wirerope 2, the fixedly connected coded lock plug 6 of the other end, key lock tapered end 10 stretch into the lockhole in the lock body 1, pin with the blade lock.Lock pipe 7 is provided with slit 11 vertically, the width in described slit 11 and coded lock plug 6 ledge width adapt, cipher wheel is made of spacer 5 and digital roller 4, numeral roller 4 one side sides evenly are provided with the coding breach along circumference, spacer 5 outer circumference surfaces are provided with the projection that cooperates with digital roller 4 coding breach, the number of coding breach is consistent with digital number on the digital roller 4, is generally 10, and is corresponding with numeral 0～9.The angle of circumference that is become between adjacent two projections is the integral multiple that becomes angle of circumference between adjacent two coding breach.Spacer 5 inner peripheral surfaces are provided with the breach of unblanking that cooperates with coded lock plug 6 projectioies, the described breach of unblanking is arranged on spacer 5 inner peripheral surface ad-hoc locations, make and to unblank breach during have coding and lock body on the unique digital roller 4 Warning Mark of unblanking corresponding over against coded lock plug 6 projectioies.Spacer 5 and digital roller 4 poststack mutually can be enclosed within rotationally and form password unlockings with coded lock plug 6 on the lock body lock pipe 7 and cooperate, and the diverse location that spacer 5 is embedded in digital roller 4 just forms different passwords.Numeral roller 4 another sides are provided with concave point, and the number of concave point equates with digital number on the digital roller 4.Lock pipe 7 also is with plane spring 3, lock pipe 7 surfaces have two grooves, the inner peripheral surface of plane spring 3 is provided with two projectioies with lock pipe 7 groove fit, projection is stuck in the groove, make plane spring 3 not rotate relative to lock pipe 7, plane spring 3 also is provided with a salient point that cooperates with digital roller 4 concave points, and salient point and concave point cooperate, can block digital roller 4 and make its location, digital roller 4 can freely not misplaced.Cipher wheel, plane spring 3 constitute one group of password combination, are enclosed within on the lock body lock pipe 7, and password is that several figure places just can be established several groups.

Lock body 1 is provided with lock housing 9, lock housing 9 is provided with rectangular window in relative cipher wheel position, described lock housing is with the swivelling cover 8 of a cross section for annular outward, swivelling cover 8 is provided with a window and a positioning convex point that size is consistent with the lock body rectangular window, when swivelling cover 8 windows forwarded to consistent with lock housing 9 windows and make positioning convex point snap in the lock housing detent, the user can see cipher wheel and can dial.The time spent is not swivelling cover counter-rotating 90.To opposite side, and positioning convex point is snapped in the lock housing detent can hide cipher wheel, and play the effect of dust cap.

Coded lock plug 6 inserts lock pipe 7 along lock body lock pipe seam crack 11, numeral roller 4 drives spacer 5 and rotates in coded lock plug 6 grooves of correspondence, has only the coding that forwards setting when all cipher wheel to, promptly when unblanking breach all during protruding on coded lock plug 6 on all spacers 5, coded lock plug 6 could be extracted release in lock pipe 7.

Certainly the utility model is not limited only to above-mentioned embodiment, and wirerope is changed into chain, steel wire, and blade is locked simple changes such as changing cylinder lock into also should be within the utility model protection domain.
