Description

Novel password lock capable of being updated without self-supply

Technical Field

The invention relates to the field of locks, in particular to a novel password lock capable of being updated without source.

Background

The password of the password lock on the market at present only has a group of passwords for the current use, can not be used alternately by a plurality of groups of passwords at the same time, and the password group needs to be reset when being replaced; the single group of passwords are repeatedly used, so that the risks of peeping and remembering exist; the lock bolts of part of the locks play a role one by one, are easy to crack, are not suitable for high-requirement encryption and are not enough. In order to overcome the defects, the applicant applies for an invention patent with a publication number of CN106337605B on 2016, 7, 15, that is, a passive automatic updating coded lock, and the lock has the advantages of order-by-order change of all groups of codes, incapability of continuous reuse, difficulty in cracking and good safety, but the lock body, the unlocking mechanism and the coded mechanism are all independently designed, so that the whole lock is complex in mechanism, large in volume and still has the defects.

Disclosure of Invention

Aiming at the defects, the invention provides a novel password lock without source update, which has the characteristics of multiple passwords, large password amount, sequential change of the passwords, incapability of continuous repeated use, difficult cracking, good safety, simple and compact structure and small volume.

In order to achieve the purpose, the technical scheme of the invention is as follows:

a novel password lock without self-renewal comprises a lock body, an unlocking mechanism and a password mechanism.

The lock body comprises a base, a cover plate and a cellular board which are installed on the base, and a lock pin arranged on the base, wherein a return spring is arranged on the lock pin.

The unlocking mechanism comprises a lock tongue column arranged in the honeycomb plate, a ratchet wheel fixedly connected to the upper end of the lock tongue column and linked with the lock pin, and a lock handle fixedly connected to the lower end of the lock tongue column, wherein multiple layers of lock tongue components are axially arranged on the lock tongue column, and the lock tongue components are a plurality of lock tongues arranged in a staggered mode.

The cipher mechanism comprises a plurality of cipher units which are arranged on a multi-layer honeycomb plate and linked with a lock tongue column, each cipher unit comprises a plurality of marbles which are matched with the lock tongue to form blocking or passing and a cipher disk which is sleeved outside the marbles, and the cipher disk is provided with a longitudinal groove which is used for containing the marbles to relieve the blocking of the lock tongue.

Furthermore, the number and the positions of the lock tongues of the lock tongue assemblies on the lock tongue columns corresponding to the plurality of code units are different.

Furthermore, the number and the positions of the marbles corresponding to the plurality of code units are different.

Furthermore, the number and the positions of the longitudinal grooves on the cipher disks corresponding to the plurality of cipher units are different.

Furthermore, letter marks are circumferentially arranged on the lock handle.

Furthermore, a notch or a mark for indicating the password input alignment mark position of the password disk is arranged on the cover plate of the base.

The invention has the beneficial effects that: the novel passive automatic updating password lock has the characteristics of multiple passwords, large password amount, no continuous and repeated use of each password group through sequential change, difficult cracking and good safety. Meanwhile, the invention adopts a highly integrated structural design, the lock tongue column for locking and unlocking is simultaneously used as a rotating shaft of the lock handle driving ratchet wheel, the traditional lock tongue column, lock column and cipher disk matching structure is designed into a lock tongue column, marble and cipher disk matching structure, and the cipher disk is externally arranged, so that the unlocking mechanism and the cipher mechanism are simplified, and the invention has the characteristics of simple and compact structure and small volume.

Detailed Description

The technical solution of the present invention is further described below with reference to the following embodiments and the accompanying drawings.

Example (b):

referring to fig. 1-4, a novel password lock without source update comprises a lock body 1, an unlocking mechanism 2 and a password mechanism 3.

The lock body 1 comprises a base 10, a cover plate 11 and a cellular board 12 which are installed on the base 10, and a lock pin 13 which is arranged on the base 10, wherein a return spring (not shown) is arranged on the lock pin 13.

The unlocking mechanism 2 comprises a bolt column 20 arranged in the honeycomb plate 12, a ratchet 21 fixedly connected to the upper end of the bolt column 20 and linked with the lock pin 13, and a lock handle 22 fixedly connected to the lower end of the bolt column 20, wherein three layers of bolt components are axially arranged on the bolt column 20, and the bolt components are a plurality of bolts 23 arranged in a staggered manner.

The cipher mechanism 3 comprises three cipher units which are arranged on the multilayer honeycomb plate 12 and linked with the bolt post 20, each cipher unit comprises a plurality of marbles 30 which are matched with the bolt 23 to form blocking or passing and a cipher disc 31 which is sleeved outside the marbles 30, and the cipher disc 31 is provided with a longitudinal groove 32 which is used for accommodating the marbles 30 to release the blocking of the bolt 23.

Further, the number and the position of the locking tongues 23 of the locking tongue assembly on the locking tongue post 20 corresponding to the three code units are different.

Furthermore, the number and the positions of the marbles 30 corresponding to the three code units are different.

Furthermore, the number and the positions of the vertical slots 32 on the combination disks 31 corresponding to the three combination units are different.

Further, the lock handle 22 is circumferentially provided with letter marks.

Furthermore, a notch or a mark (not shown) for indicating the password input alignment position of the password input disc 31 is disposed on the cover plate 11 of the base 10.

The invention sets multiple layers of lock tongue components and password disks with corresponding layers on the lock tongue column, and the number of the password bits is determined by setting the layers of the lock tongue components and the password disks. The lock tongue on the lock tongue column and the marble on the cipher disk form a locking state for blocking the rotation of the lock handle, when the cipher is input, the cipher disk is rotated to a specified digital position, so that the marble enters the longitudinal groove on the cipher disk to be unblocked, and one lattice of the rotating lock handle is an unlocking state. The invention adopts the ratchet to drive the lock pin, and the irreversible characteristic of the ratchet ensures that the password group of the invention can only be used in sequence group by group, and a single password can not be continuously reused.

The trick lock in this embodiment sets up and has the multiunit tribit password, calculates whole password group when the tool to lock sets for, indicates according to the letter mark on the lock handle when using, inquires corresponding password, rotates the lock handle one check again after rotating the dial input password and can unblock, rotates the lock handle once more when needing to lock again and can lock.

While the foregoing is directed to the preferred embodiment of the present invention, it will be understood by those skilled in the art that various changes and modifications may be made without departing from the spirit and scope of the invention.
