Description

Technical Field

[0001] This application belongs to the field of data processing equipment technology, and in particular relates to a cutting mechanism and a hard disk destruction device including the mechanism. Background Technology

[0002] When highly confidential data is stored on hard drives, its physical destruction primarily involves demagnetization followed by mechanical shredding. The aforementioned cutting mechanism, and the hard drive destruction equipment including this mechanism, are used in the mechanical shredding stage.

[0003] Generally, hard drive destruction cutting equipment mainly consists of an operating table, a vertical power cylinder, a cutting blade, and supporting structures. The basic cutting principle and method of this equipment is as follows: the cutting blade is positioned horizontally, slightly protruding beyond the operating table, and the hard drive to be destroyed also partially protrudes beyond the operating table and is located below the cutting blade. The downward stroke of the vertical power cylinder then effectively cuts and severs the drive.

[0004] Afterwards, depending on the level of confidentiality, it can be determined whether further shredding is necessary, thus completing the entire hard drive destruction process and ensuring that confidential data is not leaked.

[0005] For example, Chinese utility model patent with authorization announcement number CN213054961U and authorization announcement date of April 27, 2021 discloses a hard disk cutting device, whose main structural components include: a worktable, an upper blade holder, a spring-loaded assembly, a pressure block, an upper blade, a drive mechanism, a hydraulic cylinder seat, a column, a lower blade, a hard disk, and a lower blade holder.

[0006] The advantages of the hard drive cutting device in this utility model patent are: the cutting device has a simple structure, which can improve the cutting efficiency of hard drives to be destroyed.

[0007] However, in actual use, this hard drive slicing device still has at least the following safety deficiencies, specifically including: First, the upper and lower blades are fully exposed when not in use, making them relatively easy to be accidentally touched or bumped, posing a safety hazard of easy cuts. Secondly, when a hard drive is being cut, the only fixing effect it receives is the elastic downward pressure provided by the clamping block, which is relatively insufficient. In particular, the remaining part of the hard drive after the cutting operation is prone to tilting, slipping out, or even popping up, which is also a significant safety hazard. Utility Model Content

[0008] This application provides a cutting mechanism, the technical problem of which is to make the cutting and destruction of hard drives safer and more efficient.

[0009] In addition, this application also provides a hard disk destruction device including the above-mentioned cutting mechanism.

[0010] The technical solution adopted by this application to solve the above problems is: a cutting mechanism, the structure of which includes a vertical power cylinder, a perforated operating table unit, a gantry unit disposed on the perforated operating table unit and used to install the vertical power cylinder, a vertical cutting blade unit sleeved on the gantry unit and connected to the vertical power cylinder, an inverted U-shaped frame unit inserted on the perforated operating table unit and located below the gantry unit and used to engage and fix the hard disk, and a membrane unit disposed on the inverted U-shaped frame unit and used to cover and protect the vertical cutting blade unit when it is in use.

[0011] A further preferred technical solution is that the perforated operating table unit includes an operating table horizontal plate with the gantry unit on its upper surface, and two mounting ports on the operating table horizontal plate for inserting the inverted U-shaped frame unit.

[0012] A further preferred technical solution is that the gantry unit includes an inverted U-shaped frame body disposed on the perforated operating table unit, and a limiting rod disposed on the inner top surface of the inverted U-shaped frame body for inserting the vertical cutting blade unit.

[0013] A further preferred technical solution is that the vertical cutting blade unit includes a perforated plate sleeved on the limiting rod, a vertical blade body disposed on the side of the perforated plate, and mounting bolts disposed on the vertical blade body and used to connect the perforated plate.

[0014] A further preferred technical solution is that the inverted U-shaped frame unit includes an inverted U-shaped plate that is plugged into the two mounting ports and used for pressing down to fix and side blocking to fix the hard drive.

[0015] A further preferred technical solution is that: the inverted U-shaped frame unit further includes a slot disposed on the horizontal plate of the inverted U-shaped plate and used to receive the membrane unit; the membrane unit includes a rectangular membrane with one end disposed in the slot and the other end used to cover and protect the vertical blade.

[0016] A further preferred technical solution is that the gantry unit also includes an observation port disposed on one of the vertical plates of the inverted U-shaped frame and used to observe the lateral movement dimension of the hard disk.

[0017] A further preferred technical solution is that: the vertical cutting blade unit further includes a countersunk hole disposed on the vertical blade body and used for setting the mounting bolt; the membrane body unit further includes an elastic retaining ring disposed on the rectangular membrane body and used for inserting and engaging the countersunk hole.

[0018] A hard disk destruction device including the cutting mechanism further includes a protruding plate disposed on the lower surface of the perforated operating table unit, and a shredder or a lower fixed blade body screwed onto the side of the protruding plate.

[0019] A further preferred technical solution includes a fastening bolt disposed on the side of the protruding plate, passing through the inverted U-shaped frame unit, and used to fix the vertical height of the inverted U-shaped frame unit.

[0020] The beneficial effects of this application include at least the following seven points.

[0021] First, when the cutting mechanism is in use, the membrane unit can be unfolded to cover the vertical cutting blade unit, which protects both the vertical cutting blade unit and the operator, thus making the entire cutting and destruction operation safer and more efficient.

[0022] Secondly, the inverted U-shaped frame unit can provide a stable downward pressure effect on the hard drive at the same time, as well as a comprehensive blocking effect on both sides, ensuring that the hard drive is stable during the cutting operation and that the remaining part of the hard drive is also stable after the cutting operation.

[0023] Third, the inverted U-shaped frame unit can fix various hard drives of different thicknesses and widths, making it relatively practical. It can also serve as an indicator of the end point of the downward stroke of the vertical cutting blade unit, preventing the vertical cutting blade unit from being damaged due to excessive downward movement.

[0024] Fourth, the gantry unit enables the vertical power cylinder to control the lifting and lowering of the vertical cutting blade unit, which is precise and efficient enough.

[0025] Fifth, the membrane unit has the dual advantages of not affecting the limiting effect of the inverted U-shaped frame unit on the hard drive when stored, and being fully fixed on the vertical cutting blade unit when unfolded for use.

[0026] Sixth, this hard drive destruction device has the advantages of easy collection of cut fragments, or faster and more thorough cutting action.

[0027] Seventh, this hard drive destruction device has the advantage of stability, as the height of the inverted U-shaped frame unit is not easily changed spontaneously after adjustment, making its downward pressing and fixing effect on the hard drive more stable. Attached Figure Description

[0041] The following description is merely a preferred embodiment of this application and is not intended to limit the scope of this application.

[0042] like Figures 1-11As shown, a cutting mechanism includes a vertical power cylinder, a perforated operating table unit 1, a gantry unit 2 mounted on the perforated operating table unit 1 for mounting the vertical power cylinder, a vertical cutting blade unit 3 sleeved on the gantry unit 2 and connected to the vertical power cylinder, an inverted U-shaped frame unit 4 inserted on the perforated operating table unit 1 and located below the gantry unit 2 for engaging and fixing a hard disk a, and a membrane unit 5 mounted on the inverted U-shaped frame unit 4 for covering and protecting the vertical cutting blade unit 3 when it is in use.

[0043] In this embodiment, the main body of the cutting mechanism is made of engineering plastic, aluminum alloy, or galvanized steel. The general method of using this cutting mechanism is as follows: First, based on the thickness of hard disk a, adjust the height of the inverted U-shaped frame unit 4 so that hard disk a can pass between the upper surface of the perforated operating table unit 1 and the inner top surface of the inverted U-shaped frame unit 4, and the inner top surface of the latter should be relatively close to the upper surface of hard disk a. This ensures that hard disk a is not easy to move out laterally when being cut, can generally only be slightly tilted, and is less likely to bounce up and fall, thus improving the safety of the cutting operation. Second, the hard drive a is inserted horizontally into the inverted U-shaped frame unit 4, and its upper part protrudes from the perforated operating table unit 1. This protruding part is the part that was cut off. Third, the vertical power cylinder is activated, causing the vertical cutting blade unit 3 to slowly descend until it cuts off the hard disk a; Fourth, if the remaining part of hard disk a on the perforated worktable unit 1 is too large, the third step above can be repeated until the size of the remaining part is qualified and the cutting operation is sufficient. Fifth, the remaining parts mentioned above are collected together with the cut-off parts, and the vertical cutting blade unit 3 is reset upwards, thus completing a complete hard drive cutting operation; Sixth, after all the hard drives in this batch have completed the cutting operation, the vertical cutting blade unit 3 is in a relatively high reset state, and the membrane unit 5 is pulled out from the inverted U-shaped frame unit 4 to cover the vertical cutting blade unit 3, thus completing the entire usage process of the cutting mechanism.

[0044] The vertical power cylinder is a hydraulic cylinder, which can provide relatively greater cutting strength compared to a pneumatic cylinder. The perforated operating table unit 1 is integrally formed or welded with the gantry unit 2, the vertical cutting blade unit 3 is sleeved with the gantry unit 2, the inverted U-shaped frame unit 4 is inserted into the perforated operating table unit 1, and the membrane unit 5 is folded and stored inside the inverted U-shaped frame unit 4 for later use.

[0045] Furthermore, after the height of the inverted U-shaped frame unit 4 is adjusted, it can be fixed by the friction between it and the perforated operating table unit 1, or by installing other fastening structures.

[0046] To put it another way, precisely because the remaining part of the cut hard disk a does not exert a completely vertical upward force on the inverted U-shaped frame unit 4, even if the frictional force is relatively small, it will not significantly affect the limiting and protection effect of the inverted U-shaped frame unit 4 on the hard disk a.

[0047] Finally, the vertical projection of the vertical cutting blade unit 3 is located outside the perforated operating table unit 1, so that even if the former is slightly excessively lowered, it is not easily damaged. The main body material of the membrane unit 5 is cloth or plastic, which is sufficient to fully cover the blade portion of the vertical cutting blade unit 3.

[0048] The perforated operating platform unit 1 includes an operating platform horizontal plate 101 with the gantry unit 2 on its upper surface, and two mounting ports 102 on the operating platform horizontal plate 101 for inserting the inverted U-shaped frame unit 4.

[0049] In this embodiment, the horizontal operating table 101 is rectangular in shape, with the vertical cutting blade unit 3 at one end and the loading end of the hard disk to be cut at the other end. The mounting port 102 is rectangular or circular in shape.

[0050] Nuts can also be installed on the side of the horizontal plate 101 of the operating table to extend into the mounting port 102 and clamp the inverted U-shaped frame unit 4 whose height has been adjusted.

[0051] In addition, a metal edging strip 103 is provided on the edge of the horizontal plate 101 of the operating table, which is located directly below the vertical cutting blade unit 3, to prevent the edge from being deformed or cracked by the hard disk a. The edging strip 103 can be replaced periodically to fully protect the edge.

[0052] The gantry unit 2 includes an inverted U-shaped frame 201 mounted on the perforated operating table unit 1, and a limiting rod 202 mounted on the inner top surface of the inverted U-shaped frame 201 for inserting the vertical cutting blade unit 3.

[0053] In this embodiment, the inverted U-shaped frame 201 and the limiting rods 202 are integrally formed, with two of the latter. The vertical power cylinder is located between the two limiting rods 202, and its cylinder body is disposed on the inner top surface of the inverted U-shaped frame 201. Its push plate is screwed to the vertical cutting blade unit 3. The maximum downward movement distance of the vertical cutting blade unit 3 must ensure that it does not detach from the limiting rods 202.

[0054] The vertical cutting blade unit 3 includes a perforated plate 301 sleeved on the limiting rod 202, a vertical blade body 302 disposed on the side of the perforated plate 301, and mounting bolts 303 disposed on the vertical blade body 302 and used to connect the perforated plate 301.

[0055] In this embodiment, the word "opening" on the perforated plate 301 refers to the fact that it has both a larger open hole for inserting the limiting rod 202 and a smaller screw hole for installing the hydraulic cylinder push plate.

[0056] The number of the perforated plates 301 is one or two. Even if there is only one, it can be achieved by, for example, attaching... Figure 3 Despite its generally C-shaped shape, it still achieves relatively high insertion stability with the limit rod 202.

[0057] On the other hand, the vertical blade 302 is rectangular in shape, with its cutting edge arranged horizontally for cutting the hard disk a downwards. There are 2-6 mounting bolts 303, which are horizontally mounted on the cutting surface of the vertical blade 302.

[0058] The inverted U-shaped frame unit 4 includes an inverted U-shaped plate 401 that is plugged into the two mounting ports 102 and used for pressing down to fix and side blocking to fix the hard disk a.

[0059] In this embodiment, the central horizontal plate of the inverted U-shaped plate 401 is used to block or directly adhere to the upper surface of the hard disk a, and its two side vertical plates are respectively used to insert into the two mounting ports 102, ensuring that the inverted U-shaped plate 401 can fully block and protect various hard disks with different thicknesses and widths, thereby improving the practicality of the cutting mechanism.

[0060] The inverted U-shaped frame unit 4 also includes a slot 402 disposed on the horizontal plate of the inverted U-shaped plate 401 and used to accommodate the membrane unit 5; the membrane unit 5 includes a rectangular membrane 501 with one end disposed in the slot 402 and the other end used to cover and protect the vertical blade 302.

[0061] In this embodiment, the slot 402 is disposed on the central horizontal plate of the inverted U-shaped plate 401. The long side of the rectangular membrane 501 is its unfolding and retracting direction. One of its wide sides is bonded to the slot 402, and the other wide side is used to attach to, cover and protect the exposed blade surface of the vertical blade 302, thereby ultimately protecting the blade position of the vertical blade 302.

[0062] The gantry unit 2 also includes an observation port 203 disposed on one of the vertical plates of the inverted U-shaped frame 201 and used to observe the lateral movement dimension of the hard disk a.

[0063] In this embodiment, the main function of the observation port 203 is: First, adjust the height of the inverted U-shaped plate 401 according to the thickness of hard drive a, so that the former can pass under the middle horizontal plate of the latter, and the vertical distance is as small as possible. Second, adjust the left and right positions of hard disk a so that it can pass under the inverted U-shaped plate 401, avoiding it from hitting the side vertical plate part of the latter.

[0064] The vertical cutting blade unit 3 further includes a countersunk hole 304 disposed on the vertical blade body 302 and used for mounting the mounting bolt 303; the membrane unit 5 further includes an elastic retaining ring 502 disposed on the rectangular membrane body 501 and used for inserting and engaging the countersunk hole 304.

[0065] In this embodiment, the main functions of the countersunk hole 304 include the following two: First, it causes the head of the mounting bolt 303 to retract inward, reducing the risk of it being accidentally hooked or bumped. Secondly, an elastic locking point is provided for the elastic fixing ring 502, so that the rectangular membrane 501, which is turned upward at this time, is not easy to fall downward, thus ensuring that the protective effect of the rectangular membrane 501 on the blade is continuously effective.

[0066] The mounting bolt 303 has a relatively small head size, thus providing sufficient insertion space for the elastic retaining ring 502. The elastic retaining ring 502 is made of ordinary rubber, and its outer ring surface engages with the annular surface of the countersunk hole 304 for self-fixation.

[0067] A hard disk destruction device including the above-mentioned cutting mechanism further includes a protruding plate 11 disposed on the lower surface of the perforated operating table unit 1, and a shredder 12 or a lower fixed blade body 13 screwed onto the side of the protruding plate 11.

[0068] In this embodiment, the protruding plate 11 is rectangular or cross-shaped, and is integrally formed or screwed to the horizontal plate 101 of the operating table. On the side directly below the vertical blade 302, there are screw holes for installing the shredder 12 or fixing the blade 13 below.

[0069] The shredder 12 is rectangular in shape, with its upper end lower than the upper surface of the horizontal operating table 101. The material, shape, and structure of the lower fixed blade 13 are the same as those of the vertical blade 302, and it can be relatively smaller in size. The blade of the lower fixed blade 13 faces upward, and its height is the same as or slightly higher than the upper surface of the horizontal operating table 101, thus supporting the lower surface of the hard disk a, making the cutting action of the vertical blade 302 on the hard disk a faster and more thorough.

[0070] It should be noted that when the lower fixed blade 13 is used, the number of rectangular films 501 can be two, which are also used to cover and protect the lower fixed blade 13. Alternatively, the number can be one, but it is forked at one end, which can also cover and protect the vertical blade 302 and the lower fixed blade 13 respectively. For details, please refer to the appendix. Figure 8 .

[0071] On the other hand, the vertical blade 302 and the end face of the horizontal plate 101 of the operating table already provide the horizontal space required for the installation of the lower fixed blade 13, so as to avoid the vertical blade 302 and the lower fixed blade 13 from colliding and damaging each other.

[0072] Finally, the waste bin 12 is installed on the protruding plate 11. When the hard drive destruction device is idle, the rectangular membrane 501 can also cover it, thus ensuring that the cutting powder is not easily scattered. The hard drive cutting section also has a certain degree of concealment and privacy, which is very practical. For details, please refer to the appendix. Figure 10 .

[0073] The structure of the hard drive destruction device also includes fastening bolts 14 that are disposed on the side of the protruding plate 11, pass through the inverted U-shaped frame unit 4, and are used to fix the vertical height of the inverted U-shaped frame unit 4.

[0074] In this embodiment, the fastening bolt 14 can be used in conjunction with a row of openings on the side vertical plate of the inverted U-shaped plate 401, so that the inverted U-shaped plate 401 can achieve a fixing effect that is adjustable in stages but has relatively high stability.

[0075] Furthermore, it is relatively easier to make threaded holes on the side of the protruding plate 11 than to make threaded holes on the horizontal plate 101 of the operating table, which is one of the advantages of the protruding plate 11.

[0076] The embodiments of this application have been described in detail above with reference to the accompanying drawings. However, this application is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various modifications can be made without departing from the spirit of this application. These are non-inventive modifications and are protected by patent law as long as they are within the scope of the claims of this application.
