Abstract

A hand-hold coded lock of mobile phone sleeve belongs to the field of coded lock. The lock mainly comprises a main lock and an additional lock, and no matter the main lock or the additional lock has absolutely its own code setting structure and lock pressure plate, but shares a lock fork. The code modification of the code setting structure should be with the help of a special tool, and the safety and reliability of the lock is improved. Moreover, designed according to the hand shape, the structure of the coded lock is simplified for actual utility, can easily be arranged on the mobile phone sleeve, and which makes the mobile phone sleeve more handsome, fashionable, and conveniently opened.

Description

Cell-phone cover hand held coded lock

Technical field

The utility model relates to a kind of cell-phone cover hand held coded lock, and it belongs to the coded lock field.

Background technology

As everyone knows, generally do not establish lockset on the existing cell-phone cover, generation is often arranged,, use very inconvenient if use existing lockset to be installed on the cell-phone cover because of causing the incident that mobile phone is lost accidentally.With existing coded lock is example, and ten passwords are under the sight line situation of difficult, and it is very difficult fast sign indicating number being unblanked.Therefore it is necessary to design a kind of coded lock attractive in appearance, generous, again can convenient-opening by hand shape.

Summary of the invention

In order to improve the safety of cell-phone cover, the utility model provides a kind of cell-phone cover hand held coded lock, and this coded lock is pressed hand shape design, is installed on the cell-phone cover, makes that cell-phone cover is more attractive in appearance, fashion, but convenient-opening when needed.

The technical scheme that its technical problem that solves the utility model adopts is: a kind of cell-phone cover hand held coded lock, it mainly comprises a main lock, main lock is made up of password setting mechanism, main lock pressing plate and lock fork, and main lock cipher sets up an organization and mainly forms by being contained in the main lock cipher piece on the main lock shaft, main lock pressing plate runner and main lock spring.It also comprises an additional lock that is arranged on main lock one end, additional lock also is made up of password setting mechanism and additional lock pressing plate, and lock a shared lock with the master and pitch, additional lock cipher sets up an organization and mainly forms by being contained in the additional lock cipher piece on the additional lock shaft, additional lock pressing plate runner and additional lock spring, when password is set, additional lock shaft and additional lock pressing plate runner are moved axially to additional lock spring direction together, at this moment additional lock cipher piece can rotate separately, otherwise additional lock cipher piece and additional lock pressing plate runner can only rotate together.

Set up an organization 1～4 main lock cipher piece of cover and main lock pressing plate runner of above-mentioned main lock cipher is contained on the main lock shaft.Code number on main lock cipher piece and the additional lock cipher piece respectively is 2～5.

Above-mentioned lock is stuck the fork face one that is provided with, fork face two and fork face three, and main lock pressing plate is provided with pressure surface one and pressure surface two, and additional lock pressing plate is provided with a pressure surface three.When coded lock was in the lock attitude, fork face one contacted with pressure surface one, fork face two contacts with pressure surface two with fork face three and contacts with pressure surface three.

The guiding theory of technique scheme is: above-mentioned coded lock is to press the design of hand shape, and be installed on the cell-phone cover, this coded lock is made up of a main lock and an additional lock, main lock and additional lock are provided with password setting mechanism and pressing plate respectively, a but shared lock fork, have only when main lock and additional lock are all aimed at password, cell-phone cover could be opened.Be that the main lock or the structure of the password setting mechanism of additional lock all are identical with operating principle, only main lock cipher piece and the general unlikely cover of main lock pressing plate runner, and additional lock cipher piece and additional lock pressing plate runner have only a cover.For making simple operation, less password only is set on cryptographic block.And after password setting, could revise password by instrument, this has just increased the reliability of password, can not change password because of maloperation.

The beneficial effects of the utility model are: this cell-phone cover hand held coded lock mainly comprises a main lock and an additional lock, be that main lock or additional lock all have independently password setting mechanism and lock pressing plate, a but shared lock fork, password must could be revised by instrument by password setting mechanism, has therefore improved the safety and the reliability of lock.Add that this coded lock presses hand shape design, the angle of using from reality simplifies the structure, and very easily is installed on the cell-phone cover, makes that cell-phone cover is more attractive in appearance, fashion and unlatching be convenient.
