Abstract

An user setting cipher lock, comprises gear on a hand-wheel, its fitting rack, lock pin and cipher locking device. The structure of the cipher locking device is a trail of same tooth clamp blocks connected by a screwed shaft through at-lest one same bore, and movable fitting to the screwed shaft, and at-least one vacant location equal to the tooth vacant, and the top of the tooth clamp block fits the geared rack, on the bolt cover fixed to the rack, at-least one moving tooth with corresponding location and same quantity to the vacant location are fixed by screw, making the moving tooth movable fitting to the tooth clamp block vacant location, and the length of the tooth clamp block (L) is equal to the tooth pinch of the gear (H). The invention has advantages as simple and firm structure, easy-manufacturing, low cost and user set cipher.

Description

Certainly establish the coded lock of password by the user

Technical field

The present invention relates to a kind of coded lock, promptly user oneself is provided with the coded lock of password.

Background technology

The password of Current Password lock is by the prefabricated setting of producer, the user opens use by the password that producer is provided with, this itself does not maintain secrecy very dangerous yet, in case after password was forgotten in the use, lock then can not be opened, have only and change lock after its destruction dismantled, otherwise no way in addition, also also snatched password by the robber easily in using or take that barbarous means saws, cut, cut etc. and will lock after the destruction still can larceny, as automobile, safety cabinet is stolen happens occasionally, therefore, its theftproof is relatively poor.

Summary of the invention

Its purpose of the present invention is: provide a kind of by the user from establishing the coded lock of password, it is simple in structure, convenient processing and manufacture, oneself is provided with password the user, note well not only, and improved the confidentiality of lock is used more safe and reliable.

The present invention is achieved in that a kind of coded lock of being established password by the user certainly, comprise, the tooth bar that gear on the handwheel cooperates with it, lock core and password locking device, described password locking device be identical tooth fixture block by at least one same holes penetrate the silk axle go up form a string, and with the silk axle movingly, has an omission that equals the tooth piece on its axle at least, its tooth fixture block top cooperates with tooth bar, the affixed dead bolt of described tooth bar is with the corresponding mobile teeth of quantity and position such as at least one and omission and fixes by screw thread, make mobile tooth and the omission of tooth fixture block movingly, the long L=gears tooth pitch of tooth fixture block H.In the described handwheel wind spring is set, the outer end is affixed with axle and handwheel shell respectively in the wind spring, the affixed gear of handwheel.Vacant interior the insertion every card and with it of described tooth fixture block cooperates with the framework grafting of tooth fixture block.

The present invention is simple in structure, and convenient processing and manufacture is with low cost, can be widely used in the place that can use lock, and it can be by the user from establishing password, password is convenient to memory and is also improved being kept absolutely secret property of password simultaneously, safe and reliable, lock unbreakable, thereby the generation of stopping to steal phenomenon.

Elaborate its structure with accompanying drawing in conjunction with the embodiments.

The specific embodiment

Its structure of the present invention is as shown in Figure 1: a kind of by the user from the coded lock of establishing password, comprise, the tooth bar 4 that gear 102 on the handwheel 1 cooperates with it, lock core and password locking device, described password locking device be identical tooth fixture block 5 by at least one same holes penetrate form on the silk axle 8 a string, and with silk axle 8 movingly, has an omission 601 that equals tooth piece 5 on its axle 8 at least, its tooth fixture block 5 tops cooperate with tooth bar 4, described tooth bar 4 affixed dead bolts 7 are with the corresponding mobile teeth 702 of quantity and position such as at least one and omission and fix by screw thread, make mobile tooth and 5 omissions 601 of tooth fixture block movingly, tooth fixture block 5 long L=gears tooth pitch H.

In the described handwheel 1 wind spring 2 is set, the outer end is affixed with axle 101 and handwheel shell respectively in the wind spring 2, handwheel 1 affixed gear 102.

Insert in the omission 601 of described tooth fixture block 5 every card 6 and with it and cooperate with the framework grafting of tooth fixture block 5.

Embodiment 1

Described tooth fixture block 5 is selected 20-50, at first handwheel 1 usefulness shift fork 3 is pushed neutral position, mobile tooth 702 on the described dead bolt 7 is 1, be arranged on and the code data same position, with its grafting or be spirally connected and be fixed on the dead bolt 7, long L of tooth fixture block and pitch H are isometric, select 2mm-5mm, tooth fixture block frame subscript code data equals the figure place of each, with 2 silk axles of tooth fixture block 5 usefulness wear be fixed in the tooth bar 4 corresponding frameworks that match on, mobile tooth fixture block is made as vacant 601 places with code data and inserts every card (6), this position is a unlock position, if password finishes, 1 group on handwheel is returned engaging hole be the beginning position, unclamping handwheel can be by the collision locking.After the locking shift fork 3 being return the original state position gets final product.

The lock opening process:

Hand rotates handwheel 1 to the password position, and radula 7 moves tooth 702 and inserts the room promptly every Ka6Chu, and open the locking spring of radula this moment, and lock will be opened.

Embodiment 2

Tooth fixture block 5 is selected 50-100, and it is same as described above that it is provided with cryptographic processes, repeats no more.

Claims

One kind by the user from establishing the coded lock of password, comprise, the tooth bar (4) that gear (102) on the handwheel (1) cooperates with it, lock core and password locking device, it is characterized in that: described password locking device be identical tooth fixture block (5) by at least one same holes penetrate silk axle (8) go up form a string, and with silk axle (8) movingly, has an omission (601) that equals tooth piece (5) on its axle (8) at least, its tooth fixture block (5) top cooperates with tooth bar (4), the affixed dead bolt (7) of described tooth bar (4) is with quantity such as at least one and omission and the corresponding mobile tooth in position (702) is fixed by screw thread, make mobile tooth and tooth fixture block (5) vacant (601) movingly, the long L=gears tooth pitch of tooth fixture block (5) H.
2. as claimed in claim 1 by the user from establishing the coded lock of password, it is characterized in that: wind spring (2) is set in the described handwheel (1), interior the outer end of wind spring (2) respectively and axle (101) and handwheel shell affixed, the affixed gear of handwheel (1) (102).
