Description

The novel cipher lock

Technical field

The utility model relates to mechanical code lock, specifically is a kind of novel cipher lock.

Background technology

Simple to operate, advantage of wide range of application that mechanical code lock has, but because self structure restriction, the problem that its password of existing machinery coded lock ubiquity is stolen easily, promptly the stealer can rotate rotating disk limit pulling tapered end by the limit and try out password, thereby opens coded lock; Based on this, be necessary to invent and a kind ofly can effectively prevent the novel mechanical cipher lock that password is stolen.

Summary of the invention

The utility model provides a kind of novel cipher lock in order to solve the problem that its password of existing machinery coded lock is stolen easily.

The utility model is to adopt following technical scheme to realize: the novel cipher lock comprises lock housing; Be provided with locking bar in the lock housing; The locking bar middle part is with at least two rotating disks that its central authorities have through hole, and locking bar runs through through hole; The rotating disk side surface is carved with numeral or symbol; Through-hole wall equidistantly is arranged with at least three password grooves; Described password groove comprises a groove and at least two blind grooves, and wherein, groove runs through rotating disk both sides end face along the through-bore axis direction, and blind groove port is positioned at a side end face of rotating disk; Locking bar is provided with at least two lock teeth; The number of the number of described rotating disk, password groove all is decided according to the actual requirements.

The course of work is as follows: when coded lock is in locking states, the lock tooth is aimed at blind groove or the groove on the rotating disk, and rotate rotating disk this moment, makes that all grooves on the rotating disk are aimed at lock tooth (being that password is correct), lock tooth simultaneously and advance backward, thereby coded lock is opened along groove; Attempt by rotating rotating disk when snatching password as the people, external force acts on locking bar, makes the lock tooth embed blind groove or the groove on the rotating disk backward, causes rotating disk to rotate, and makes that thus the stealer can't continue to snatch password; So compare with the existing machinery coded lock, the password theft difficulty of novel cipher lock described in the utility model is bigger, so it has possessed higher safety.

Further, the socket of locking bar rear end is fixed with sleeve, is connected with spring between sleeve inner bottom surface and the locking bar rear end end face; Rotating disk both sides end face is respectively concave surface and convex surface, and the locking bar front end fastens tapered end; The lock housing surface have with rotating disk side surface position over against display window; During work, tapered end can supporting connection chain, lock ring etc., and the locking bar front end is embedded in the tapered end, spring is in pressure condition in the wrong, produce pressure in external force under to the effect of tapered end and make locking bar indentation backward, the locking bar front end separates with tapered end, and the numeral that is engraved on the rotating disk side surface shows by display window.

Further, the lock housing surface has installing hole; The number of display window is seven, and wherein six display windows are positioned at the installing hole left side, and a display window is positioned at the installing hole right side; The number of rotating disk is eight, and wherein seven rotating disks are corresponding one by one with seven display window positions, rotating disk and position of mounting hole over against; Nested connection between the adjacent discs; During work, the numeral that is engraved on eight rotating disk side surfaces is formed eight passwords, and eight passwords show by display window and installing hole.

In addition, the cross section of lock tooth can be certain slope, and the lock tooth can be embedded in the locking bar by elastic device; When locking, in the lock tooth withdrawal locking bar, when the lock tooth was in the rotating disk centre, the lock tooth was ejected by elastic device, when unblanking, the lock tooth can not withdrawn in the locking bar automatically, like this, no matter when locking or unblank, rotating disk all is in free rotation state substantially, thereby make password (numeral or symbol) uncertain, safety is higher.

At last, the degree of depth of each blind groove can be designed to deep mixed; Its benefit is to have increased the difficulty of trying out password.

The utility model is simple in structure, reasonable in design, efficiently solves the problem that its password of existing machinery coded lock is stolen easily, is applicable to the security protection in all kinds of places such as bicycle, family, bank.
