Abstract

The invention discloses a mechanism for limiting rotation of a cipher disk. The mechanism comprises a lock cylinder, a blocking column, a spring, an ejecting rod, the cipher disk and a locking column. The two ends of the ejecting rod installed in the lock cylinder are ejected on the circumference of a large-diameter segment of the blocking column and an arc groove of the cipher disk so that the cipher disk cannot rotate; and only when a small-diameter segment on the blocking column is aligned with the ejecting rod, can the cipher disk rotate. Several blocking columns, ejecting rods and cipher disks can be installed as required; and the positions of locking column pull-out holes in each cipher disk are different, the arrangement category number for setting different ciphers is achieved, the positions of small-diameter segments on the blocking columns are changed, the arrangement category number of key groove depths is achieved, and the locking column can be pulled out only when each cipher disk rotates to the corresponding locking column pull-out hole and coincides with the locking column. It is difficult to make each cipher disk rotate through an unlocking tool, other persons have difficulty in rotating each cipher disk to the set cipher position if they got a key, but do not know the ciphers, a lock provided with the mechanism has the double-anti-theft performance that other persons have difficulty in opening the lock, and the mechanism can be used on non-motor vehicle locks, anti-theft door locks, safety box locks and the like.

Description

The mechanism that limit for cryptographic dish rotates

Technical field

The present invention relates to a kind of lock, particularly relate to the mechanism that a kind of limit for cryptographic dish rotates.

Background technology

Existing traditional type spring lock, can open lock, existing coded lock (or claiming combination lock) with corresponding unlocking tool Combination disk can be freely rotatable, the probability of lock is opened in easy appearance at random, these two kinds lock theftproof performances not good enough.

Within 2009, I has applied for the utility model patent of safety lock, the patent No.: 200920098733.8, in order in this lock The mechanism that limit for cryptographic dish rotates is used in locking of other purposes, after deliberation with trial-production after, it is proposed that again apply for patent of invention.

Summary of the invention

The technical problem to be solved is to provide the mechanism that a kind of limit for cryptographic dish rotates, and has other people and is difficult to beat The double theftproof performances unblanked, can be used on bicycle and lock, on safe-guard door lock and safe lock is first-class.

In order to solve above-mentioned technical problem, the technical solution used in the present invention is: the mechanism that a kind of limit for cryptographic dish rotates, Including core, bumping post, spring, push rod, combination disk and lock, it is characterized in that, the two ends of the push rod being arranged in core are pushed up respectively On the circumference of bumping post enlarged diameter section and combination disk arc groove on, make combination disk not rotate, when on bumping post reduced diameter section with During push rod centering, combination disk could rotate, and can install several bumping post, push rod and combination disk as required, and each combination disk is locked The position of post pulled-out holes is different, it is achieved set the arrangement kind number of different password, changes the position of reduced diameter section on bumping post, it is achieved key The arrangement kind number of spoon depth of groove, the most each combination disk forwards lock pulled-out holes to when overlapping with lock, and lock just can be extracted.

The invention has the beneficial effects as follows: be mounted with several bumping post, push rod and combination disk because locking, be difficult to make with unlocking tool Each combination disk can rotate, and other people take key and do not know password, it is also difficult to each combination disk is forwarded to the close of setting Code position, the lockset installing this mechanism has other people to be difficult to the double theftproof performances opened.

Detailed description of the invention

With detailed description of the invention, the present invention is described in further detail below in conjunction with the accompanying drawings: Fig. 1 is that combination disk can not turn Dynamic schematic diagram, Fig. 2 is the rotary schematic diagram of combination disk.The mechanism that limit for cryptographic dish rotates includes core, bumping post, bullet Spring, push rod, combination disk and lock, the two ends of the push rod 4 being arranged in core 1 withstand on the circumference of bumping post 2 enlarged diameter section respectively With on the arc groove of combination disk 5, combination disk 5 is made not rotate, when reduced diameter section and push rod 4 centering on bumping post 2, combination disk 5 Could rotate, several bumping post 2, push rod 4 and combination disk 5 can be installed as required, the position of lock pulled-out holes 6 in each combination disk 5 Put difference, it is achieved set the arrangement kind number of different password, change the position of reduced diameter section on bumping post 2, it is achieved key 8 depth of groove Arrangement kind number, the most each combination disk 5 forwards lock pulled-out holes 6 to when overlapping with lock 7, and lock 7 just can be extracted.

As in figure 2 it is shown, after inserting key 8, by the pressure of bumping post 2 spring 3 above, make on lower end and the key 8 of bumping post 2 Corresponding recesses contacts, and when only depth of groove is suitable, just can make reduced diameter section and push rod 4 centering, rotational password dish 5 on bumping post 2 Time, compressing push rod 4 to left movement, the pressure of the spring 3 by being enclosed within push rod 4, make the right-hand member of push rod 4 all the time with combination disk 5 Periphery contacts, and every turn of position of combination disk 5, push rod 4 moves back and forth once.

Claims

1. the mechanism that limit for cryptographic dish rotates, including core, bumping post, spring, push rod, combination disk and lock, is characterized in that, The two ends of the push rod (4) being arranged in core (1) withstand on the circumference of bumping post (2) enlarged diameter section and the circle of combination disk (5) respectively On arc groove, making combination disk (5) not rotate, when the upper reduced diameter section of bumping post (2) is with push rod (4) centering, combination disk (5) could turn Dynamic, several bumping post (2), push rod (4) and combination disk (5) can be installed as required, the upper lock pulled-out holes (6) of each combination disk (5) Position different, it is achieved set the arrangement kind number of different password, change the position of the upper reduced diameter section of bumping post (2), it is achieved key (8) The arrangement kind number of depth of groove, the most each combination disk (5) forwards lock pulled-out holes (6) to when overlapping with lock (7), lock (7) just can extract.
