Abstract
The utility model relates to a compute power supply with a lock, comprising a power supply shell and a power switching circuit arranged in the power supply shell, wherein the power supply shell is provided with a power input end and a power output end which are respectively connected with the power switching circuit. The computer power supply with the lock is characterized in that a power line at the power input end is connected with a power lock in series. The computer power supply with the lock has reasonableness in design, realizes the function of controlling opening of the computer by the series connection of the power lock in the power switching circuit, improves security measures of the computers, and has the characteristics of simple operation, convenient use, flexible installation, wide application range, and the like.
Description
Technical field
The utility model belongs to field of power supplies, especially a kind of computer power supply with lock.
Background technology
Computing machine brings great convenience for our work and life, only need open the computer power supply work of can starting shooting in use.But, also can bring some problems if use a computer ad lib, for example, in family, youngsters and children often has no to use a computer temperately and chats on line, plays games, sees video etc., therefore influence teen-age normal study and life, need take measures to prevent that youngsters and children from arbitrarily opening computer and using; In office, some computing machine has specificity or confidentiality, can not can not arbitrarily be browsed by the people by the data that other people arbitrarily use or computing machine is stored and consult, therefore must take certain safety practice to these special purpose computers, the unlatching of control computer is used.Limit though at present computer cryptography can be set,, by shortcomings such as there are setting in the password Starting mode and use that inconvenience, password are forgotten easily, therefore limited its scope of application.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of computer power supply with lock reasonable in design, easy to use is provided.
The utility model solves its technical matters and takes following technical scheme to realize:
A kind of computer power supply with lock, comprise power shell and inner power-switching circuit thereof, power shell is provided with power input and also is connected with power-switching circuit respectively with power output end, series connection one power supply lock on a power lead of power input.
And described power supply lock is installed on the power shell.
And described power supply lock is installed on the computer cabinet by extended line.
Advantage of the present utility model and good effect are:
1, this computer power supply is connected on the power supply lock between one power lead and the power-switching circuit, break-make by power supply lock control power supply, realization is to computing machine control of turning function, can control on the one hand in the family youngsters and children effectively to the use of computing machine, can improve computer security performance and the security performance in the office on the other hand, have characteristics simple to operate, easy to use.
2, this computer power supply can be installed in the power supply lock on the power shell according to different user demands, also can be installed in any position of computer cabinet by extended line, has characteristics flexible for installation, that the scope of application is extensive.
3, the utility model is reasonable in design, by being connected on, realized between a power lead and the power-switching circuit by the power supply lock computing machine control of turning function, improved the safe and secret measure of computing machine, had simple to operate, easy to use, flexible for installation and characteristics such as the scope of application is extensive.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is a circuit block diagram of the present utility model.
Embodiment
Below in conjunction with accompanying drawing the utility model embodiment is further described:
A kind of computer power supply with lock, as shown in Figure 1, comprise power shell 1 and inner power-switching circuit thereof, a side end face is provided with louvre 2, power supply lock 3 and power input 4 on the power shell, during installation, this side end face of power shell is exposed at outside the computer cabinet.Other side end faces at power shell are provided with the power output end (not shown).The annexation of power input, power output end, power supply lock and power-switching circuit as shown in Figure 2, power input is connected with AC power, be in series with the power supply lock between one power lead of power input and the power-switching circuit, promptly a power lead is connected on the terminals of power supply lock, another terminals of power supply lock insert on the power-switching circuit, and another power lead and the ground wire of power input are directly connected on the power-switching circuit.Power-switching circuit is the reference power supply circuit, and it carries out AC power, and power source conversion produces direct supply and through coupled power output end output, the direct supply of power output end output provides the power supply support for whole computing machine.
This computer power supply is by the switch realization power input of power supply lock and the break-make control function of power-switching circuit, and when the power supply lock was in open mode, the power supply lock disconnected this power lead and power-switching circuit, and computer power supply is in off position; When the power supply lock was in closed condition, the power supply lock disconnected this power lead and power-switching circuit, and computer power supply is in off position.Opening and closing of power supply lock is by realizing with the power supply key of the phase-locked coupling of this power supply.
The foregoing description is that the power supply lock is installed on the power shell, in fact, this power supply lock can also be installed in the outer any place of power shell by extended line, for example is installed on the computer cabinet, and to open any position of closing all passable so long as be convenient to the power supply lock.
It is emphasized that; embodiment described in the utility model is illustrative; rather than it is determinate; therefore the utility model is not limited to the embodiment described in the embodiment; every by those skilled in the art according to other embodiments that the technical solution of the utility model draws, belong to the scope of the utility model protection equally.
