Abstract

The utility model discloses a suitcase code lock. relating to the improvement to the structure of the suitcase code lock. The utility model is designed in order to solve the problem that the security performance of the suitcase code lock is poor at present. The structural points of the utility model lies in that a positioning disc is provided with a lockhole and an anti poking hole; outer teeth of the positioning disc is engaged with inner teeth of the same number disc; both sides of the positioning disc are at the inner of both sides of the number disc; an outer groove of the number disc is contacted with a positioning spring of the body; a movable rod is provided with an inserted rod corresponding to the lock hole; a right end of the movable rod is provided with a spring and a rack; a left side of a central shaft is fastened on the lock body by the spring and the other end of the central shaft is provided with a regulation handle; the rack of the movable rod is engaged with small gears of the gear of the lock body; large gears of the gear is provide with the spring and engaged with the rack of a lock tongue corresponding to a lock buckle opening; the lock opening is contacted with the spring in the hole groove by a slide; the lock buckle is fastened on the lock body shaft. The utility model adopts the double discs engagement design of the positioning disc and the number disc to increase safety and reliability of the lock.

Description

The case and bag coded lock

Technical field:

The case and bag coded lock relates to the improvement of case and bag coded lock structure.

Background technology:

Present case and bag coded lock, a kind of is vertical wheel lock, another kind is a horizontal wheel lock.The common dialer device of vertical wheel lock is made up of a figure disc and a positioning disk, and positioning disk has a groove; The unlatching of this lockset generally enters the positioning disk groove by knob drive lockset inner projection and finishes; Because case and bag require the lockset can not be too big, thus projection generally all on same plane, same straight line.And the attached number side that hangs over of positioning disk, groove is very easily found out, and the confidentiality of this lock is not fine.Horizontal wheel lock is exactly the figure disc lateral rotation, figure disc structure relative complex, and outside figure disc integral body was exposed to, groove was below figure disc; Be with it spring and raised structures relatively; Its opening process roughly is, the lateral rotation figure disc is to the password position, and spring is with bulge-structure jacking groove, thereby lockset reaches opening; Though this lockset is found out less than groove from outward appearance, when projection entered groove, spring force disappeared, so can feel that it is password that raised structures enters groove from figure disc; Therefore the guarantor's sealing that should lock is also undesirable.

Summary of the invention:

The utility model is exactly the problem that solves present case and bag coded lock security performance difference.

The technical solution adopted in the utility model is to comprise lock body, snap close, its structural feature is to have lockhole on the positioning disk on the axis on the lock body, anti-dial hole, the external tooth of positioning disk is meshed with the internal tooth of figure disc, and the both sides of positioning disk are in the both sides of figure disc, the outer grooves of figure disc contacts with the positioning reed on the lock body, have on the trace and the corresponding inserted link of lockhole, the right-hand member of trace has spring, tooth bar, the left end of axis is fixed on the lock body with spring, the other end of axis has the adjustment pull handle, the tooth bar of trace is meshed with the pinion of the gear on the lock body, the gear wheel of gear is with having spring, be meshed with the tooth bar of the corresponding dead bolt of fore shaft of snap close, fore shaft contacts with the spring in the hole slot by slide block, and snap close is fixed on the axle of lock body.

The beneficial effects of the utility model are: owing to adopted the double plate engagement design of positioning disk, figure disc, and the both sides of positioning disk have just fully prevented finding out from outer bound pair password in the both sides of figure disc; Being provided with anti-dial hole is to prevent to utilize shearing force and technology foozle to unblank; Be provided with positioning reed, make the directed rotation of figure disc, extend greatly, also increased the security reliability of this lock thereby make by number check mark uncaging time.

The specific embodiment:

The utility model comprises lock body 17, snap close 3, has lockhole 26 on the positioning disk 23 on the axis 19 on the lock body 17, anti-dial hole 29, the external tooth 25 of positioning disk 23 is meshed with the internal tooth 24 of figure disc 15, and the both sides of positioning disk 23 are in the both sides of figure disc 15, the outer grooves 27 of figure disc 15 contacts with the positioning reed on the lock body 17 28, have on the trace 14 and lockhole 26 corresponding inserted links 13, the right-hand member of trace 14 has spring 12, tooth bar 8, the left end of axis 19 is fixed on the lock body 17 with spring 18, the other end of axis 19 has the pull handle 10 of adjustment, the tooth bar 8 of trace 14 is meshed with the pinion 5 of the gear on the lock body 17 7, the gear wheel 6 of gear 7 is with having spring 11, be meshed with the tooth bar 9 of the fore shaft 2 corresponding dead bolts 1 of snap close 3, fore shaft 2 contacts with the spring 21 in the hole slot 22 by slide block 20, and snap close 3 is fixed on the axle 4 of lock body 17.

The anti-dial hole 29 of lock of the present utility model can be set to 1-3.

Narrate a course of action of the present utility model below:

The locked state of this lock:

At first snap close 3 is compressed into hole slot 22 around axle 4, the slide block 20 in the hole slot 22 is compressed spring 21; Meanwhile, under the effect of spring 11, dead bolt 1 enters in the fore shaft 2, promptly is locked state.

The unlocking condition of this lock:

At first figure disc 15 is pushed desired location, at this moment, the toggle 16 that can move to right (inserted link 13 enters in the lockhole 26 of positioning disk 23 simultaneously), trace 14 just drives tooth bar 9 and is moved to the left by tooth bar 8, gear 7; Meanwhile, snap close 3 moves right under the effect of spring 21, ejects hole slot 22, and slide block 20 promptly is unlocking condition with hole slot 22 sealings.
