DETAILED DESCRIPTION

[0027] The specific implementation of the utility model will be further described in detail below with reference to the accompanying drawings.

[0028] The anti-theft chassis with alarm function in this specific implementation mode is as follows: Figure 1-5 As shown, it includes a chassis body 1 and a chassis cover 2 covering the side of the chassis body 1. The inner wall of the chassis body 1 is fixedly connected with a power supply port 102, the power supply port 102 is connected to a power supply installed inside the chassis body 1, and a raised copper sheet is arranged inside the power supply port 102;

[0029] The back of the chassis cover 2 is fixedly connected with an alarm device 3, and the alarm device 3 is powered by a power supply port 102;

[0030] The alarm device 3 includes a power supply plug 301, on which two electrode sheets 302 are mounted to overlap the inside of the power supply port 102 for power supply, and a connecting wire 303 is led out of the electrode sheet 302, and an electromagnetic switch 304 is mounted at the end of the connecting wire 303, and an alarm 305 is connected to the electromagnetic switch 304. When the electromagnetic switch 304 is powered on, the alarm 305 is adsorbed to cut off the power, and when the electromagnetic switch 304 is powered off, the alarm 305 is powered on and emits an alarm sound.

[0031] Through the above technical scheme, a power supply port 102 is set inside the chassis body 1 to be connected to a power supply installed inside the chassis body 1, and a power supply plug 301 is set on the back of the chassis cover 2 and plugged into the power supply port 102 to power the electromagnetic switch 304, so that the power supply of the alarm 305 is disconnected. When the chassis cover 2 is opened, the electromagnetic switch 304 is powered off and then closed under the action of metal elasticity, so that the alarm 305 emits an alarm sound through electricity, thereby achieving the effect of sounding an alarm when the chassis cover is opened, thereby improving the safety of components inside the computer chassis.

[0032] Specifically, a lock buckle 101 is fixedly connected inside the chassis body 1, and a latch hole 201 is opened on the chassis cover 2. The lock buckle 101 and the latch hole 201 cooperate with each other to further fix the chassis cover 2 through a padlock.

[0033] Through the above technical solution, a lock buckle 101 is provided on the chassis body 1 and a latch hole 201 is opened on the chassis cover 2 for fixing a padlock, thereby further fixing the chassis cover 2 to avoid accidental opening of the chassis cover 2 and preliminarily preventing the devices inside the chassis body 1 from being stolen.

[0034] Specifically, a vent 202 is provided on the chassis cover 2 , and the vent 202 is close to the alarm 305 .

[0035] Through the above technical solution, a vent 202 is opened on the chassis cover 2, and the vent 202 and the alarm 305 are close to each other. During the use of the computer chassis, the vent 202 can assist in the heat dissipation inside the computer chassis. When the alarm 305 sounds an alarm, the sound is transmitted outward through the vent 202, thereby improving the sound transmission effect of the alarm 305 and achieving the effect of assisting heat dissipation and increasing the alarm volume.

[0036] Specifically, a groove is provided on the power plug 301 , the electrode sheet 302 is located inside the groove, and the electrode sheet 302 is elastic.

[0037] Through the above technical solution, a groove is set on the power plug 301, so that the power plug 301 is limited by the groove and the inside of the power port 102, and the electrode sheet 302 is elastic, the purpose of which is to improve the stability of the contact between the electrode sheet 302 and the copper sheet inside the power port 102.

[0038] Specifically, the electromagnetic switch 304 includes a protective shell 3041, an electromagnet 3042 and a button battery 3044 are installed inside the protective shell 3041, an elastic metal sheet 3043 is installed between the electromagnet 3042 and the button battery 3044, the elastic metal sheet 3043 is made of iron, the electromagnet 3042 is connected to the power supply plug 301, and the elastic metal sheet 3043 and the button battery 3044 are respectively connected to the two poles of the alarm 305.

[0039] Through the above technical solution, the protective shell 3041 is used to protect the components inside it, and the protective shell 3041 has a cover that can be opened. When the electromagnet 3042 inside the protective shell 3041 is energized, it generates magnetism to adsorb the elastic metal sheet 3043, so that the elastic metal sheet 3043 is separated from the top of the button battery 3044, so that the button battery 3044 interrupts the power supply to the alarm 305. When the electromagnet 3042 is powered off and loses its magnetism, the elastic metal sheet 3043 falls and overlaps the button battery 3044 to supply power to the alarm 305, so that the alarm 305 emits an alarm sound.

[0040] During maintenance, the alarm of the alarm 305 can be interrupted by opening the cover on the protective shell 3041 and taking out the button battery 3044. However, people who are not familiar with this structure cannot quickly disconnect the button battery 3044 to interrupt the alarm of the alarm 305.

[0041] Specifically, the interior of the electromagnet 3042 is an electromagnetic coil, the elastic metal sheet 3043 is overlapped on the top of the button battery 3044, and the top of the elastic metal sheet 3043 is fixedly connected with an iron metal block.

[0042] Through the above technical solution, the electromagnetic coil will instantly generate magnetic attraction after being energized, so that the end of the elastic metal sheet 3043 can be effectively adsorbed, and the iron metal block is set on the top of the elastic metal sheet 3043. The purpose is as follows: first, to enhance the adsorption strength between the electromagnet 3042 and the elastic metal sheet 3043. Second, it is used to provide weight to the elastic metal sheet 3043. After the electromagnet 3042 loses its magnetism, it can accelerate the falling speed of the elastic metal sheet 3043 and reduce the rebound of the elastic metal sheet 3043, so as to achieve the effect of quickly energizing the alarm 305 to alarm.

[0043] Specifically, the protective shell 3041 is made of insulating material, and a gap is left between the protective shell 3041 and the power plug 301 .

[0044] Through the above technical solution, the protective shell 3041 is provided with insulating material, so as to avoid arcing electricity when it is too close to the mainboard and cause the mainboard to be broken down. The gap between the protective shell 3041 and the power plug 301 is used to avoid obstruction when the power plug 301 is plugged into the power port 102.

[0045] When in use, the power supply port 102 is provided inside the chassis body 1 to connect with the power source installed inside the chassis body 1, and the power supply plug 301 is provided on the back of the chassis cover 2 to be plugged into the power supply port 102 to supply power to the electromagnetic switch 304, so that the power supply of the alarm 305 is disconnected. When the chassis cover 2 is opened, the electromagnetic switch 304 is powered off and then closed under the action of metal elasticity, so that the alarm 305 emits an alarm sound through electricity, thereby achieving the effect of sounding an alarm when the chassis cover is opened, thereby improving the safety of the components inside the computer chassis;

[0046] By opening a vent 202 on the chassis cover 2 and placing the vent 202 and the alarm 305 close to each other, during the use of the computer chassis, the vent 202 can assist in dissipating heat inside the computer chassis. When the alarm 305 sounds an alarm, the sound is transmitted outward through the vent 202, thereby improving the sound transmission effect of the alarm 305 and achieving the effect of assisting heat dissipation and increasing the alarm volume.

[0047] It should be noted that although specific embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these specific embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
