Abstract

The utility model discloses a storage medium destroyer, comprising a shell, a driving mechanism arranged in the shell and a couple of rollers which are driven to rotate by the driving mechanism. The rollers are accompanied with loopy gear teeth, the two rollers are arranged abreast, the gear teeth on the rollers are in malocclusion, and the nearest gear teeth of the two rollers are slightly overlapped and arranged. Inlets of storage medium are arranged on the corresponding positions of the middles of the two rollers accompanied with the gear teeth on the shell. The working principle of the utility model is that: a power supply is switched on, the two rollers accompanied with the gear teeth are driven to rotate oppositely by the driving mechanism, and thus the storage medium clamped and squeezed between the two rollers are grinded or cut off. The grinding of the utility model is thorough, other people are unable to recover the information of the storage medium and read the information on the extant storage medium, and the security is good.

Description

Mechanical type storage medium destroyer

Technical field

The utility model relates to a kind of device that is used to destroy the storage medium that stores various information, for example is used to destroy the device of the CD that stores various information, floppy disk, USB flash disk, IC-card, magnetic card etc.

Background technology

At present, people often adopt some data of storage or data such as CD, floppy disk, USB flash disk, IC-card, magnetic card.For units such as government department, army, high-tech department, finance, these information that are stored on the storage medium belong to classified information basically, can not arbitrarily abandon.When abandoning them, need a kind of means of destroying to destroy these information above medium, to guarantee national information safety.

Summary of the invention

In order to destroy the storage medium that stores various information, make other people can not recover, analyze the information that remains on the storage medium, the purpose of this utility model provides a kind of destroyer that is used to destroy the storage medium that stores various information.

For achieving the above object, the utility model is taked following design: a kind of mechanical type storage medium destroyer, and it is made of housing, the transmission mechanism and a pair of roller bearing by the transmission mechanism driven rotary that are fixed in the housing;

Described roller bearing is fixed in the housing, links to each other with transmission mechanism, and roller bearing is provided with teeth of enclosing; Two roller bearings are arranged side by side, and the centre distance between the roller bearing is slightly less than two roller bearing maximum radius sums, make the overlapping slightly setting of teeth nearest on two roller bearings; And, the interlaced interlock of teeth on two roller bearings;

On described housing, have the inlet of storage medium with described two corresponding sections, centre position that have a roller bearing of teeth.

In specific embodiment of the utility model,

Described transmission mechanism comprises motor, the reduction box that links to each other with motor output shaft, gear train; The described roller bearing that has teeth links to each other with gear train; Described motor rotates in opposite directions by reduction box, two roller bearings that have teeth of gear set drive.

Operation principle of the present utility model is: drive two roller bearings that have teeth by transmission mechanism and rotate in opposite directions; Thereby, the storage medium of pinching between two roller bearings pulverized or cut off.

The utility model has the advantages that: simple in structure, applied widely, can thoroughly destroy the information on the storage medium, security is good.

Since the utility model be have teeth by two and teeth between the roller bearing of mutual dislocation interlock rotate in opposite directions, the storage medium of pinching between two roller bearings pulverized or cut off, so, the utility model is big to the storage medium active force of pinching between two roller bearings, storage medium thoroughly can be pulverized or cut into a pile fragment; Other people can't be recovered, analyze the information that remains on the storage medium, so security is good.In addition, the utility model can be destroyed polytype storage medium, and is applied widely.

The specific embodiment

Destroy for the storage medium that will store various information, make other people can not read the information that remains on the storage medium, mentality of designing of the present utility model is with these storage mediums pulverizing or cuts into fragment, makes it and can't restore.

As shown in Figure 1 and Figure 2, the disclosed mechanical type storage medium of the utility model destroyer mainly is made of housing 1, the transmission mechanism 2 and a pair of roller bearing that has teeth 3 that is fixed in the housing 1 that are installed in the housing 1; Transmission mechanism 2 drives a pair of roller bearing 3 and rotates in opposite directions, thereby the storage medium 4 of pinching between a pair of roller bearing 3 pulverized or cut off.

As shown in the figure, described transmission mechanism 2 comprises a motor 21, a reduction box that links to each other with motor output shaft 22 and gear train 23; The roller bearing 3 that has teeth links to each other with gear train 23.After motor 21 is connected power supply, rotate by reduction box 22 driven gear groups 23, gear train 23 drives two roller bearings 3 and rotates in opposite directions.

As shown in Figure 3, Figure 4, be densely covered with teeth of enclosing 31 on the roller bearing 3.Roller bearing 3 can go out teeth 31 (as shown in Figure 3) by the direct car of lathe, also can emit 34 to be fixed on the axle 35 and to make the roller bearing 3 (as shown in Figure 4) that has teeth by axle sleeve 33, spiral shell the some gear pieces 32 that have teeth 31.

For with the pulverizing such as floppy disk of pinching between a pair of roller bearing 3, described a pair of roller bearing 3 is arranged side by side, and as Fig. 2, shown in Figure 5, the centre distance between the roller bearing 3 is slightly less than two roller bearing maximum radius sums, makes the overlapping slightly setting of teeth nearest on two roller bearings; And, make two teeth 31 interlaced interlocks on the roller bearing.

As Fig. 2, shown in Figure 5, operation principle of the present utility model is: connect power supply, make motor 21 rotations, motor 21 rotates by reduction box 22 driven gear groups 23, gear train 23 drives two roller bearings 3 and rotates in opposite directions, and the storage medium of pinching between two roller bearings 3 pulverized or cut off.

For this reason, the utility model has inlet 11 with the corresponding section, centre position of two roller bearings on housing 1, so that storage mediums such as disk, CD are inserted between two roller bearings in the housing.

In time remove totally in order to remain in powder in the teeth, as Fig. 6～shown in Figure 9, the utility model is fixed with a cleaning catch 5 below each roller bearing.Have several grooves 51 on the cleaning catch 5, the teeth 31 on the roller bearing 3 just are embedded in the groove 51 that cleans on the catch 5.

The utility model in housing, two roller bearings below also be provided with a container 12 that is used to deposit crushed material.For the ease of maintenance, the utility model is an open-type with the upper cover design of housing 1, and loam cake 13 can be opened along rotating shaft 14.

In the above-described embodiments, the utility model drives roller bearing 3 rotations by motor 21, reduction box 22 and gear train 23, certainly can also adopt alternate manner that two roller bearings are rotated in opposite directions, for example directly a pair of roller bearing is rotated in opposite directions, or two roller bearings are rotated in opposite directions by motor, belt, pulley by two motors.

The above is specific embodiment of the utility model and the know-why used, but protection domain of the present utility model is not limited thereto, and is any based on the equivalent transformation on the technical solutions of the utility model basis, all belongs within the utility model protection domain.
