Description

The mainframe box of band alarm

One, technical field:

The utility model relates to a kind of computer equipment, especially a kind of mainframe box with alarm.

Two, background technology:

At present, computer occupies immeasurable effect in live and work, it is a kind of instrument of people's information communication, is the daily necessities that people needn't lack, but in the Internet bar, school, industrial enterprise, it is stolen that memory bar, hard disk, the CD-ROM drive of main frame can often appear in computer, Internet bar particularly is when surfing the Net at dead of night, because staff's negligence, memory bar, hard disk in the main frame are stolen often, bring a lot of troubles and worry uneasiness for like this boss of Internet bar.

Three, summary of the invention:

The purpose of this utility model provides a kind of mainframe box with alarm.

Concrete scheme of the present utility model is: a kind of mainframe box with alarm, comprise cabinet, and it is characterized in that: alarm is installed in cabinet.

The trigger of above-mentioned alarm is installed on the mounting bracket in the cabinet, and trigger contacts with fastener on the chassis lid.

This programme is provided with trigger switch by the mounting bracket in the cabinet, fastener on the chassis lid contacts with trigger, when taking chassis lid apart, fastener on the case lid does not contact with trigger, make trigger be in closure state, entire circuit conducting, the alarming horn that the connects trigger caution of sounding.

Adopt the beneficial effect of such scheme to be: can avoid the computer member in the cabinet to be stolen by the thief, play warning function, it is effective to report to the police, dependable performance, and easy for installation, cost is low.

Four, description of drawings:

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is the circuit diagram of alarm 2.

Five, embodiment:

From Fig. 1, Fig. 2 as can be known: the utility model mainly is made up of cabinet 1, alarm, mounting bracket 4, fastener 5, chassis lid 6, it is characterized in that: in cabinet 1 alarm is installed.

As can be seen from Figure 1: the trigger 3 of alarm is installed on the mounting bracket 4 in the cabinet, and trigger 3 contacts with fastener 5 on the chassis lid 6.

As can be seen from Figure 2: alarm mainly is made up of power supply, integrated package, trigger 3 (K switch), triode T1, T2, transformer T3, loudspeaker D.

The utility model is work like this, when the chassis lid 6 of cabinet 1 is taken apart, fastener 5 on the chassis lid 6 does not contact with trigger 3 (K switch), trigger 3 this moment (K switch) is in closure state, the entire circuit conducting, source current amplifies through triode T1, T2 to triode T1, T2, electric current through integrated package after overcommutation, filtering, and voltage boosts through transformer T3, and last loudspeaker D sends chimes of doom.
