Description

Technical Field

[0001] The present invention relates to the technical field of computer equipment, in particular to a computer hardware anti-theft device. Background Art

[0002] In the popular scene of e-sports hotels, high-configuration computer mechanical hardware has become a risk target for theft. Due to the frequent and complex personnel turnover in e-sports hotels, traditional anti-theft methods are difficult to deal with. Common mechanical hardware such as graphics cards and CPUs are of high value and are easily coveted by criminals. Some thieves are familiar with computer hardware disassembly and can quickly disassemble and take away.

[0003] A patent application with application number CN202320349510.4 discloses an anti-theft chassis for computer hardware, including a chassis shell and a chassis cover, a heat dissipation module and an interface module are installed on the surface of the chassis shell, an alarm module is installed on the surface of the chassis cover, and the alarm module includes a connecting line, and an alarm is connected at the center of the connecting line.

[0004] To sum up, since the interior of the e-sports hotel room is a private and relatively closed environment, thieves can easily interfere with the chassis through interference equipment, which will cause the alarm module inside the chassis to fail. When the thief forcibly destroys the chassis, the hardware inside the chassis will have no protection, which will cause damage to the computer hardware and may make it easy for the thief to disassemble the hardware inside the computer and take it away.

[0005] To this end, we propose a computer hardware anti-theft device. Summary of the invention

[0034] The protection mechanism 2 includes a connecting frame 205 slidably connected to the inner wall of the chassis protection shell 101, a protection panel 201 is fixedly connected to the outer wall of the connecting frame 205 away from the chassis protection shell 101, a handle 203 is fixedly connected to the top outer wall of the protection panel 201, a first protection lock 202 is arranged inside the handle 203, the first protection lock 202 is fixedly connected to the protection panel 201, and a second protection lock 204 is fixedly connected to the bottom inner wall of the protection panel 201.

After the computer hardware inside the chassis protective shell 101 is cooled and cooled, the hot air is discharged through the first heat dissipation hole 102. When the bottom of the chassis protective shell 101 is soaked in water, the airbag 104 drives the first sliding frame 103 to move upward, and the chassis protective shell 101 is reinforced and protected from the bottom, thereby preventing thieves from damaging the computer hardware from the external heat dissipation area.

[0038] Example 2: Please refer to Figure 4-Figure 8 On the basis of the first embodiment, the present invention provides a technical solution: the adjustment component 210 includes a second sliding frame 2101 slidably connected to the mounting rod 208, the inner wall of the second sliding frame 2101 is fixedly connected with a hydraulic rod 2104, the output end of the hydraulic rod 2104 is fixedly connected with a sliding rod 2109, the central axis of the hydraulic rod 2104 is fixedly connected with an adjustment hole 2105, the hydraulic rod 2104 can only be telescopically adjusted after an external hydraulic device of a specified model is inserted into the adjustment hole 2105, thereby preventing thieves from adjusting the hydraulic rod 2104, thereby improving the protection of computer hardware, the outer surface of the second sliding frame 2101 is provided with a third heat dissipation hole 2102, the number of the third heat dissipation holes 2102 is two, and the two third heat dissipation holes 2102 are symmetrically arranged with the central axis of the force block 2106 as the center, the inner wall of the second sliding frame 2101 is provided with a through hole 2103, and the outer wall of the second sliding frame 2101 is provided with a force block 2106.

One end of the first spring 2108 away from the force block 2106 is fixedly connected to the second sliding frame 2101. After the force block 2106 is squeezed, the force block 2106 pushes the first connecting rod 2107 toward one side of the mounting hole 209, so that the position of the second sliding frame 2101 can be fixed to prevent the second sliding frame 2101 from being moved. The frame 2101 moves after the hardware is installed, and the first spring 2108 is movably sleeved on the outer surface of the first connecting rod 2107. The first connecting rod 2107 is slidably connected to the mounting hole 209. When the computer hardware to be protected comes into contact with the force block 2106, the force block 2106 pushes the first connecting rod 2107 toward one side of the mounting hole 209, thereby fixing the second sliding frame 2101 on the mounting rod 208 to prevent the second sliding frame 2101 from moving along the mounting rod 208 and causing damage to the computer hardware.

[0040] The outer surface of the sliding rod 2109 is slidably connected to the through hole 2103, and a force plate 21010 is provided on the outer wall of the sliding rod 2109 close to the force block 2106.

The outer wall of the clamping plate 21015 on one side close to the rotating rod 21014 is fixedly connected to a third spring 21016. The third spring 21016 is used to adjust the contact angle between the clamping plate 21015 and the computer hardware, thereby increasing the contact area between the clamping plate 21015 and the computer hardware.

The inner wall of the arc rod 21017 away from the end of the second connecting block 21012 is rotatably connected to the rotating rod 21014.

[0043] The working principle of this embodiment is as follows: when the computer hardware needs to be reinforced and protected, after the force block 2106 is squeezed by the computer hardware, the force block 2106 pushes the first connecting rod 2107 toward one side of the mounting hole 209, thereby fixing the second sliding frame 2101 on the mounting rod 208 to prevent the second sliding frame 2101 from moving along the mounting rod 208, and the sliding rods 2109 on both sides are moved toward the side of the computer hardware through the hydraulic rod 2104. When the force plate 21010 comes into contact with the computer hardware, the force plate 21010 pushes the second connecting block 21012 to flip the rotating rod 21014 toward the side of the computer hardware, thereby clamping and fixing the computer hardware through the clamping plate 21015, thereby protecting and clamping the computer hardware, thereby increasing the difficulty for thieves to disassemble.
