Description

Anti-theft computer case

Technical Field

The invention relates to the field of computer cases, in particular to an anti-theft computer case.

Background

The computer case is usually a cuboid and comprises a front panel, a rear panel, a left panel, a right panel, an upper panel and a lower panel, wherein a power switch key and a front USB interface are arranged on the front panel; power interfaces, video interfaces, network interfaces, etc. are typically on the back panel; after the left panel is opened, the components such as the memory, the display card, the mainboard and the like which are arranged in the case can be disassembled.

In daily life, in public places where computers are concentrated, such as internet bars, schools or enterprise computer rooms, and the like, because most computers do not adopt anti-theft measures, devices inside the computers are often stolen. Because the computer memory bank is directly inserted into the memory bank slot of the mainboard, the left end and the right end are fixed only through the movable clamp, and the memory bank can be easily taken down by pulling the clamp with bare hands, the memory bank is the most easily stolen element in the computer, and the memory bank price rises greatly in two years, so that the probability of the memory bank being stolen is increased.

Aiming at the safety problem of computers in public places, the most common anti-theft scheme at present is to add a mechanical anti-theft device to a computer case. However, the mechanical anti-theft device cannot be monitored in real time in general, and has a time delay property in response to an event, resulting in low safety.

To solve the above problems, chinese patent publication No. CN105159418B discloses an anti-theft computer case based on a smart phone, which includes: the system comprises a computer case, a pressure sensor, a gravity acceleration sensor, a gyroscope sensor, a wireless communication module, a microprocessor and a smart phone; the pressure sensor is used for sensing stress information of the left baffle and the right baffle of the computer case; the gravity acceleration sensor is used for sensing vertical position information of the left baffle and the right baffle of the computer case; the gyroscope sensor is used for sensing the angle position information of the left baffle and the right baffle of the computer case; the microprocessor is used for judging whether the computer case is disassembled or not and sending alarm information through the wireless communication module when the computer case is judged to be disassembled; the intelligent mobile phone is used for receiving the alarm information sent by the wireless communication module.

According to the scheme, the stress information and the motion information of the left baffle and the right baffle of the computer case are sensed through the pressure sensor, the gravity acceleration sensor and the gyroscope sensor which are arranged on the left baffle and the right baffle of the computer case, so that whether the computer case is maliciously forcibly dismantled or not is judged; if so, the related information is sent to the intelligent mobile phone of the manager through the wireless communication module, so that the manager can judge which computer has problems in time and take corresponding measures.

According to the scheme, the computer case can be monitored and alarmed in real time, and timeliness is good. However, in an internet bar or a computer room, electronic equipment is more, an electromagnetic environment develops, communication between a wireless communication module and a mobile phone is easily interfered, and an alarm cannot be given or is not given in time, so that how to realize the memory bank theft prevention of a computer case under the condition that network communication is not needed is a problem to be solved.

wherein, the first button seat, the second button seat and the hydraulic pipe are filled with oil.

Basic scheme principle and effect:

1. the first switch is arranged outside the clamp for fixing the memory bank, when a person pulls the clamp to take down the memory bank, the buzzer is triggered to alarm, and the purpose of anti-theft alarm is achieved;

2. the mainboard of the computer can also generate heat after long-term operation, particularly the south bridge and the north bridge on the mainboard generate relatively large heat, but generally no heat dissipation measure is taken, after the fin plate is installed, the heat of the mainboard is transferred to the heat dissipation fins of the fin plate, compared with the back of the mainboard, the heat dissipation fins have larger contact area with the air and can fully exchange heat with the air, thereby the heat dissipation is faster, and the heat dissipation of the mainboard is facilitated;

3. the radiating fins have negative charges, and dust floating in the case can be adsorbed on the radiating fins due to electrification, so that the dust in the case can be collected, the excessive dust is prevented from being attached to each element of the mainboard, and faults such as poor contact and the like of a certain element on the mainboard are avoided.

Furthermore, the radiating fins are elastic sheets, and the distance between the outer ends of the radiating fins and the right panel is smaller than the diameter of the metal ball.

When the metal ball falls downwards, the distance between the outer end of the radiating fin and the right panel is smaller than the diameter of the metal ball, the metal ball can be in contact with the outer end of the radiating fin, the radiating fin is elastically deformed under the downward pressure of the metal ball, and after the metal ball continuously falls and is separated from the radiating fin, the radiating fin vibrates back under the action of elastic force, so that dust adsorbed on the radiating fin can be shaken off.

Furthermore, a groove is arranged right below the contact piece, and the distance from the bottom of the groove to the contact piece is smaller than the diameter of the metal ball.

After the metal ball dropped the recess, metal ball upper end and heat radiation fins and contact offset, metal ball lower extreme and circumference were supported, it also can not make the metal ball remove to rock the quick-witted case, the computer lasts the switch-on, buzzer lasts the warning, if want to let buzzer stop to report to the police, need unpack the right panel apart, take out the metal ball again, and this time is longer, even the thief wants through this kind of mode cancellation alarm, also can discover because the alarm makes a sound for a long time, it is effectual to prevent burglary.

Furthermore, a silica gel pad is arranged between the back surface of the main board and the back surface of the fin plate.

The silica gel pad is insulating, can prevent the influence of the static of fin board to the mainboard, and simultaneously, the silica gel pad heat conductivity is good, and the heat of mainboard can pass to the fin board fast through the silica gel pad on.

Further, the hydraulic pipe is a metal hose.

Compared with a plastic hose, the metal hose has high surface hardness, and can prevent a thief from easily shearing the hose. The positions of main board memory slots on the market are not uniform, and the position of the first switch needs to be determined according to the positions of the memory slots. If sell the quick-witted case of giving customer's own equipment, uncertain customer can choose which kind of mainboard for use, so uncertain first switch need install in what place, but metal collapsible tube can buckle, when first switch mounted position changed, does not influence being connected between first switch and the second switch, so adopt metal collapsible tube can adapt to most mainboards.

Furthermore, the first switch is provided with a plurality of connectors, and one end of the hydraulic pipe is provided with a plurality of connectors.

When inserting many DRAM on the memory slot of mainboard, a plurality of first switches can be connected to the hydraulic pressure pipe, no matter which DRAM takes off, all can trigger bee calling organ, and it is effectual to prevent burglary.
