Description

Technical Field

[0001] The invention relates to the technical field of information carrier destruction, in particular to a computer hard disk extrusion destruction device. Background Art

[0002] In this era of big data, the demand for hard disks for storing information is increasing. Hard disks contain sensitive information. Directly discarding or selling hard disks can easily lead to important information leakage. Therefore, simply clearing the files and data on the hard disk cannot completely delete the important information on the hard disk. The hard disk must be completely destroyed to ensure that the data on the hard disk cannot be read again. Therefore, hard disk destruction technology needs to continue to develop.

In addition, the technical solutions and technical features between the various embodiments can be combined with each other, but they must be based on the ability of ordinary technicians in the field to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0122] The embodiment of the present invention provides a computer hard disk crushing and destruction device, such as Figure 1-5 As shown, including:

[0123] A box body 1, wherein a silencer is arranged in the box body 1;

[0124] An extrusion and destruction component 2 is arranged in the housing 1 and is used for extruding and destroying the hard disk;

[0125] The driving device 3 is arranged in the box body 1 , and the driving device 3 is connected to the extrusion and destruction component 2 and is used to drive the extrusion and destruction component 2 .

[0126] Preferably, the silencing device comprises: silencing cotton arranged on the inner wall of the box body 1; the silencing device has the advantage of simple structure;

[0127] A first opening is provided at one side of the box body 1 , and a first sealing door 11 that can be opened and closed is provided at the first opening. The first sealing door 11 is provided for opening the box body 1 to clean out the destroyed hard disk in the box body 1 .

[0128] The working principle and beneficial effects of the above technical solution are:

[0129] The present invention destroys the computer hard disk by extrusion by setting an extrusion destruction component 2 (achieving the purpose of making data unreadable and unwritable after the hard disk is destroyed); and a silencer is set to reduce the noise of the entire device.

[0130] The invention solves the defects that a large shearing force is needed when directly shearing and crushing the hard disk, which increases the power of the motor and the wear of the cutter, and also generates large noise pollution.

[0131] Furthermore, the present invention adopts non-shearing destruction, thereby removing the cutter of the existing hard disk destruction machine and reducing the destruction cost.

[0132] In one embodiment, Figure 1-5As shown, the extrusion destruction component 2 includes:

[0133] A movable template 21 and a static template 22, wherein the movable template 21 is connected to the driving device 3 and driven by the driving device 3; preferably, a control panel 12 is provided on the box body, and control buttons (such as control buttons for controlling the start and stop of the driving device) are provided on the control panel 12, and the operation of the driving device can be controlled through the control panel.

[0134] A plurality of first extrusion blocks 211 are evenly arranged on one side of the movable platen 21 close to the static platen 22, and a plurality of second extrusion blocks 221 are evenly arranged on one side of the static platen 22 close to the movable platen 21, and the first extrusion blocks 211 and the second extrusion blocks 221 are arranged crosswise, and the hard disk is used to be placed between the first extrusion blocks 211 and the second extrusion blocks 221;

[0135] The sides of the first extrusion block 211 and the second extrusion block 221 are uniformly arranged with a plurality of cutting edges 23 (such as Figure 6-7 As shown, the first extrusion block 211 and the second extrusion block 221 are both quadrangular pyramids and are arranged crosswise;

[0136] A second opening is provided at the top of the box body between the moving template and the static template for placing a hard disk, and a second sealing door that can be opened and closed is provided at the second opening.

[0137] The working principle and beneficial effects of the above technical solution are as follows: the hard disk is placed between the dynamic template 21 (first extrusion block 211) and the static template 22 (second extrusion block 221) from the second opening, and the dynamic template 21 is pushed toward the static template 22 under the pushing action of the driving device 3, so that the gap between the first extrusion block 211 and the second extrusion block 221 becomes smaller and smaller, and the sharp front parts of the first extrusion block 211 and the second extrusion block 221 break the surface of the hard disk. During the extrusion process, the four cutting edges 23 of the first extrusion block 211 and the second extrusion block 221 tear the hard disk at the same time. Under the dual effects of extrusion and tearing, the hard disk forms a wavy deformation and many evenly distributed small holes, so that the information on the hard disk can no longer be read and written, thereby achieving the purpose of destruction.

[0138] In one embodiment, based on the previous embodiment, Figure 8-9 As shown, the angle between the cutting edge 23 and the vertical line where it is located ( Figure 8 The vertical line is a line perpendicular to the tail end face of the first extrusion block 211 or the second extrusion block 221 (i.e., the end face of the extrusion block connected to the dynamic template and the static template, which is the vertebral bottom of the conical structure), and the head of the first extrusion block 211 and the second extrusion block 221 are both provided with a pressure buffer platform 25. The area size of the buffer platform should protect the extrusion block and should not reduce the extrusion force too much.

[0139] The working principle and beneficial effects of the above technical solution are as follows: the above angle facilitates cutting and squeezing of the hard disk;

[0140] A buffer platform is provided at the head of the extrusion block to increase the service life of the extrusion block and avoid the fragility of the sharp extrusion block head.

[0141] In one embodiment, the driving device 3 is a hydraulic driving device 3, such as Figure 1-2 As shown, including:

[0142] The hydraulic station 31 and the hydraulic cylinder 32 are both arranged in the box body 1 . The hydraulic oil outlet of the hydraulic station 31 and the hydraulic oil inlet of the hydraulic cylinder 32 are connected through an oil pipe.

[0144] In the present application, the hydraulic station 31 is a small hydraulic station 31, such as a small ultra-high pressure hydraulic station 31;

[0145] The working principle and beneficial effects of the above technical solution are as follows: the hydraulic station 31 provides pressure hydraulic oil to the hydraulic cylinder 32 to drive the hydraulic cylinder 32 to extend and retract to drive the moving template 21 to move closer to or away from the feed template;

[0146] The hard disk is destroyed by hydraulic drive extrusion, thereby removing the high-power motor of the existing hard disk destruction machine, reducing the size of the whole machine and the demand for energy, and making it more applicable.
