Description

Technical Field

[0001] The utility model relates to a data storage safety protection system. Background Art

[0002] Solid-state drives are currently the mainstream data storage product. When used to store important data, even if the data has been deleted, it can still be recovered through data recovery technology. Only by completely destroying its storage components at the physical level can the security of the data be guaranteed. Summary of the invention

[0003] Therefore, in order to completely destroy the storage elements of the solid-state hard disk that has stored important data, the utility model optimizes and upgrades the existing solid-state hard disk structure and designs a data storage security protection system.

[0004] The technical solution adopted by the utility model is:

[0005] A data storage safety protection system comprises a shell, a circuit board, a grinding disc, a downward pressure spring, a transmission gear, a supporting grid, a driving gear, a clockwork spring, a pin, a cover and a bearing.

[0006] The shell is in a rectangular shape, with a circuit board installation cavity penetrating from front to back; a circular grinding cavity is provided downward near the front end on the top surface of the shell, and the grinding cavity is connected to the circuit board installation cavity; a circular bearing support shell is provided on the top surface of the shell at the rear end of the grinding cavity.

[0010] The sanding disc is a flat cylinder with a vertical central axis. A triangular prism is fixed at the top center of the sanding disc, and the horizontal cross-sectional profile of the triangular prism is an equilateral triangle. The bottom surface of the sanding disc rests on the top surface of the memory chip. The sanding disc is located in the center of the grinding cavity.

[0011] Furthermore, the sanding disc is formed by consolidating abrasives with relatively high hardness.

[0012] Furthermore, the outer diameter of the grinding disk is greater than the maximum diagonal length of the memory chip.

[0013] The transmission gear is a flat cylinder with a vertical central axis. A cylindrical transmission gear central column is fixed along the central axis of the transmission gear. The height of the transmission gear central column is greater than the thickness of the transmission gear. The top and bottom of the transmission gear central column extend out of the top and bottom sides of the transmission gear respectively. A triangular cavity is opened on the bottom surface of the transmission gear central column. The triangular cavity is downwardly mounted on the triangular column, and the horizontal cross-sectional profile of the triangular cavity is an equilateral triangle. Bearings are mounted on the top and bottom of the transmission gear central column.

[0014] The downward pressure spring is installed in the triangular cavity and is located between the top surface of the triangular column and the top surface of the triangular cavity.

[0015] Furthermore, the gap between the side surface of the triangular prism and the side surface of the triangular cavity is less than 0.05 mm.

[0016] The support grid is in the shape of a circular ring, fixed on the top surface of the shell, and located at the top of the grinding chamber; the central axis of the support grid is colinear with the central axis of the grinding chamber; a plurality of thin cylindrical spokes are fixed horizontally on the inner cylindrical surface of the support grid toward the central axis of the support grid, and a center ring is fixed to the inner ends of the spokes; the center ring is in the shape of a circular ring, and is located at the center of the support grid; the bearing set at the bottom of the central column of the transmission gear is embedded in the center ring.

[0017] The driving gear is a flat cylinder with a vertical central axis, and a flat cylindrical mainspring installation cavity is opened downward on the top surface of the driving gear; a cylindrical driving gear central column is fixed along the central axis of the driving gear, and the top and bottom of the driving gear central column extend out of the top and bottom sides of the driving gear respectively; a flat cylindrical step platform is fixed to the bottom end of the driving gear central column extending out of the top of the driving gear, and a mainspring inner end clamping hole is opened horizontally through the cylindrical surface of the step platform; bearings are installed on the top and bottom of the driving gear central column, and the bearing installed on the bottom of the driving gear central column is embedded in the bearing support shell; the driving gear is meshed with the transmission gear, and a driving gear limiting hole is opened horizontally on the outer vertical surface of the driving gear towards the central axis of the driving gear.

[0018] Furthermore, the outer diameter of the stepped platform is greater than the outer diameter of the central column of the driving gear.

[0019] The mainspring is installed in the mainspring installation cavity, the inner end of the mainspring is fixed with a thin cylindrical inner end plug, the outer end of the mainspring is fixed with a thin cylindrical outer end plug, and the inner end plug is inserted in the inner end clamping hole of the mainspring.

[0020] Furthermore, the central axis of the inner plug is horizontal, and the central axis of the outer plug is vertical.

[0021] A transmission cavity is formed at the bottom of the cover, and the cover is fixed to the top of the shell, and the mainspring, driving gear, transmission gear, supporting grid and frosting disk are encapsulated in the transmission cavity; a transmission bearing cavity is formed on the top surface of the transmission cavity, just above the central column of the transmission gear, and the bearing mounted on the top of the central column of the transmission gear is embedded in the transmission bearing cavity; a drive bearing cavity is formed on the top surface of the transmission cavity, just above the central column of the drive gear, and the bearing mounted on the top of the central column of the drive gear is embedded in the drive bearing cavity.

[0022] A spring outer end clamping hole is provided on the top surface of the cover near the rear end and penetrates downward, and the spring outer end plug is installed in the spring outer end clamping hole.

[0023] A cover insertion hole is horizontally opened forward on the rear end vertical surface of the cover, and the cover insertion hole is communicated with the transmission cavity.

[0024] The insertion pin is a thin cylinder with a horizontal central axis. The outer end of the insertion pin is provided with a sheet-shaped handle. The insertion pin passes through the cover insertion hole from the outside to the inside and is inserted into the limiting hole of the driving gear to limit the rotation of the driving gear.

[0025] The principle of the utility model is as follows: in the initial state, the mainspring is in a tightened state, and the pin limits the driving gear to prevent it from rotating freely. When important data is stored in the memory chip and the user needs to physically destroy the memory chip, the pin is pulled out, and the driving gear starts to rotate under the drive of the mainspring, and the driving gear drives the transmission gear to rotate, and the transmission gear drives the grinding disc to rotate. During the rotation process, the grinding disc is simultaneously subjected to the elastic force of the downward pressure spring, and continuously grinds the memory chip downward into powder.

[0026] The outer diameter of the driving gear is much larger than the outer diameter of the transmission gear. One rotation of the driving gear can drive the transmission gear to rotate multiple times. The energy stored in the tightened mainspring is sufficient to grind the storage chip into powder.

[0027] The utility model provides a data storage security protection system with the following advantages:

[0028] (1) The double-gear transmission structure is used to convert the elastic potential energy of the spring after it is tightened into kinetic energy, and the storage chip is eventually physically destroyed, which is practical and reliable.

[0029] (2) The storage chip is physically destroyed through elastic potential energy to prevent the leakage of important data and ensure the security of data storage. This is a novel idea.

[0030] Therefore, this data storage security protection system can completely destroy the storage elements of the solid-state hard disk that has stored important data, and optimize and upgrade the existing solid-state hard disk structure.

[0031] Other features and advantages of the present invention will be described in the following description or may be understood through implementation of the present invention. BRIEF DESCRIPTION OF THE DRAWINGS
