Abstract

The utility model relates to an adjustable code anti-theft lock. A lock opening member which is outwards extended is transversely and fixedly connected to a rear lock rod (4) on the basis of the traditional key lock The notch of the lock opening member (5) is mutually matched with the notch of a code wheel arranged on a code member to form an enciphering and decoding mechanism, therefore, a mechanical secrecy principle is realized, and the structure of the traditional mechanical secrecy lock is simplified. The adjustable code anti-theft lock is provided with 100 < 2 >-100< 8 > codes. The adjustable code anti-theft lock can be widely used for a door, a storehouse, a secret chamber, a safe, etc. The adjustable code anti-theft lock has anti-dialing and anti-prizing functions. A unique code adjusting mechanism is designed by the adjustable code anti-theft lock, and the function of the adjustable code anti-theft lock is perfected.

Description

A kind of adjustable Cipher safety theftproof lock

The utility model relates to a kind of adjustable Cipher safety theftproof lock, and it can be widely used in door, warehouse, secret room, safety cabinet etc.

Existing puzzle theft-proof lock before the utility model, complicated in mechanical structure, for example the CN87208471U utility model patent is provided with groove master, passive dial, special-shaped dead bolt etc., complicated in mechanical structure, cost height.

The purpose of this utility model provides a kind of simple in structure, the adjustable Cipher safety theftproof lock that cost is low, machine insurance is strong, function of keeping secret is good.

Of the present utility model being described in detail as follows:

Structure of the present utility model comprises: preceding lock body, lock gall (2), rear locking (11), dead bolt (12), dead bolt box (13) or the like, go up the laterally affixed one outwardly directed part that undoes the lock (5) at lock gall (2) to the bar that undoes the lock (4) between the rear locking (11), in the rotation round scope of the part that undoes the lock (5), with the part that undoes the lock (5) 1-6 cipher wheel (7) that has concavity password door (8) is set vertically, password part fixed mount (3) about by lock gall (2) rear portion screw and stretch to the left and right, be used for bolster (15), the gear (6b) that is fixed with on the axle (15), cipher wheel (7); Gear (6b) and engagement vertical mutually with gear (6a), gear (6a) is fixed on the axle (14), and an end and the password figure dish (1) of axle (14) are affixed, and the other end passes the trepanning on the rear board (10).When coded lock is in locking states, the recess positive alignment cipher wheel (7) of the part that undoes the lock (5), at this moment cipher wheel (7) can freely be rotated; Stir combination disk (1), rotate by axle (14) driven gear (6a), gear (6a) driven gear (6b) rotates, gear (6b) drives cipher wheel (7) by axle (15) again and rotates, when combination disk (1) goes to the password that presets when counting on the aligning dish red, its password door (8) is just in time aimed at the route of part (5) rotation that undoes the lock, the part (5) that undoes the lock this moment can rotate freely, lock is in decrypted state, can unblank with key: behind the Key for lock locking, dial random combination disk (1), lock is in the encryption locking states again.

Password options button of the present utility model (9) is positioned between lock gall (2) and the rear locking (11), be provided with password options button (9), its upper arm is provided with guide groove (9a), guide groove locating part (10A) on the rear board (10), the shaft hole sleeve of options button (9) underarm be contained in be positioned at the axle (15) cog (6b) behind, establish a bayonet lock (17) between underarm axis hole and spring (16), by the pin card (17) of spring (16) elastic top under the underarm axis hole of password options button (9), and make gear (6b) and gear (6a) mutually near engagement.When needs change password, press the upper arm of options button (9), bayonet lock (17) on the underarm compressing axle (15) of options button, driving whole password member moves, compress spring (16) simultaneously, because moving of password member, make the engagement between gear (6b) and the gear (6a) get loose, can stir combination disk (1) this moment and change password, after the change of secret code, unclamp password options button (9), the elastic force of spring (16) returns back to top whole password member, gear (6b) and gear (6a) are meshed again, and the password options button resets, and the operation of change password is finished.

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is that the A-A of Fig. 1 is to partial sectional view;

Schematic diagram when Fig. 3 is the part that undoes the lock of the present utility model (5) for the wheel-shaped body of band recess;

Fig. 4 is the utility model schematic diagram of part (5) when radial that undo the lock.

The utility model is with simple in structure and undo the lock reliably joining between part (5) and the password wheels (7) Close and replaced traditional labyrinth, for example: Chinese utility model CN872084710 such by The structure that the passive driver plate of groove master, special-shaped dead bolt etc. consist of. Make its designs simplification, optimize machine Tool safety and function of keeping secret all are improved and have reduced manufacturing cost. Have 100²-100 ⁸Individual password, the user selection of leaving, when being in encrypted state, lock gall is blocked by heavy, key Or other object all can not rotate or stir lock core, therefore have anti-ly dial, pick-proof, mechanical performance Reliable characteristics.

Embodiment 1, of the present utility model a kind of adjustable Cipher safety theftproof lock as shown in Figure 1 and Figure 2; Its structure is as follows: go up the crosswise fixed one outwardly directed radial part that undoes the lock (5) (seeing accompanying drawing 4) at lock gall (2) to the back locking bar (4) between the rear locking (11); The cipher wheel (7) of 2 band password doors (8) vertically is set in the circumference range of the part that undoes the lock (5) rotation; Password part fixed mount (3) about by lock gall (2) rear portion screw and stretch to the left and right, be used for bolster (15), axle (15) is gone up fixed gear (6b), cipher wheel (7); Gear (6b) and engagement vertical mutually with gear (6a), gear (6a) is fixed on the axle (14), and an end and the password figure dish (1) of axle (14) are affixed, and the other end passes the trepanning on the rear board (10).Between lock gall (2) and rear locking (11), be provided with password options button (9), its upper arm is provided with on guide groove (9a), the rear board (10) guide groove locating part (10a), the shaft hole sleeve of options button (9) underarm is contained on the axle (15) of gear (6b) position, back, between underarm axis hole and spring (16), establish a bayonet lock (17), by spring (16) elastic top against bayonet lock (17), make gear (6b) and gear (6a) intermesh.8 to being the key direction of insertion among Fig. 1.
