Abstract
The utility model relates to a cipher keyboard privacy cover which comprises a cover body. The utility model is characterized in that the cover body is formed by gluing a plurality of annular transparent bodies with different diameters, and a nontransparent glue joint coat is arranged between two adjacent annular transparent bodies. The utility model has the advantages of novel design, simple structure and easy use. The cover can avoid the cipher being known by other people and being stolen, and accordingly the cipher keyboard privacy cover can effectively maintain normal social economy and safety order, and has good prospects of application and development.
Description
Affiliated technical field
The utility model relates to the secret cover of a kind of code keypad.
Technical background
At present, keyboard has become a kind of most important computer external input equipment, it not only can finish normal literal input, and as a kind of cipher input, be widely used in fields of society, as finance and communication fields such as bank, cash dispenser, supermarket, stock market, cipher telephones.But there is unsafe problem of using in present code keypad, generally be the front portion of the radical occlusion device design of keyboard in the operating position, can not effectively shelter from the operating position, when the user inputs password, other people can clearly see input process in closer distance, therefore occur password leakage and stolen situation easily,, the normal economic order of society is caused harmful effect to such an extent as to steal, crime such as swindle.
Summary of the invention
The purpose of this utility model just is to provide a kind of code keypad secret cover, and it is simple structure not only, is convenient to user's operation, and can effectively solves operator's problem that password is peeped by other people easily when operation keyboard.
The technical solution of the utility model is achieved in that and comprises and it is characterized in that cover body: the ring-type transparent body that described cover body is not waited by several diameters glueds joint and forms, and has the splicing coating between the two adjacent ring-type transparent bodies.
During use, the user can be buckled on it on keyboard or the display screen, because being gluedd joint by the ring-type transparent body, cover body forms, make this cover of maintaining secrecy have only or the angle in display screen the place ahead can printing opacity from the keyboard top, so the operator can see the inside of maintaining secrecy and covering clearly downwards or from display screen the place ahead from the keyboard top, and all can't see clearly from any angle of side, even this makes that other people also can be because of refractive power or interception at in-plant side and can't see the operating position or the display screen of keyboard, prevent the result of use peeped thereby reach.
The utility model is safe and secret, and simple structure is economical and practical, is convenient to user's operation and use, has bigger application development prospect.

Embodiment
Introduce concrete device and the working condition of the utility model embodiment below in conjunction with accompanying drawing:
With reference to Fig. 1-3, the utility model embodiment one is made of the ring-type transparent material, and its underpart one side has opening 1.The ring-type transparent body 2 splicing that its several diameters of cover body do not wait form, and have the coating 3 of splicing between the two adjacent ring-type transparent bodies, and this splicing coating is nontransparent shading coating.
During installation, only need the utility model is directly covered on existing code keypad outside, or code keypad is placed in the of the present utility model secret cover that has base.During operation, the operator can stretch into the inherent keyboard 4 of cover of maintaining secrecy from opening with hand and carry out operations such as password input, and eyes can be from the cover top of maintaining secrecy (or see through the cover top of maintaining secrecy opening) observes input status.And because the refractive power and the interception of ring-type cover body and nontransparent splicing coating make that covering side from maintaining secrecy can't see operator's the action of hand on keyboard clearly, thereby reach the effect that prevents password leakage.
With reference to Fig. 4, the ring-type transparent body 2 of the utility model embodiment two can be made up of polyhedral transparent body.
With reference to Fig. 5-6, the utility model embodiment three also can be provided with an opening 5 at the cover body top of the cover of maintaining secrecy, so that user's operational observations.
The utility model is novel, and is not only simple in structure, easy to use, and can stop password leakage and stolen phenomenon, thereby effectively safeguards normal social economy and safe order, has bigger application development prospect.
