Background
With the development of information technology, the information technology greatly facilitates the work and life of people, and in the field of information technology, information is spread by using data as carriers for storage.
In the big data era, data is often valuable as a carrier of information, so that numbering needs to be carried out according to needs. In the currently used data evidence storing and obtaining method based on the block chain, service data of a target service, which needs to be uplink-linked at a service node, is declared at each service node of a call link in a pre-calibration mode, so that in the processing process of the target service, the service data declared in an annotation mode can be automatically obtained at the corresponding service node and uploaded to the block chain for storage.
Most of the existing data storage evidence devices are cabinet-shaped, the required large space is used, the storage disc is replaced more inconveniently, and the dust is easy to fall into the device after long-time use, so that the data transmission efficiency is influenced.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a data deposit card device based on regional chain possesses less volume, is convenient for change and maintains the storage disc.
In order to achieve the above object, the utility model provides a following technical scheme: a data evidence storage device based on a regional chain comprises a rotary shell, a shell rotating shaft, a fixed shell and a data storage device. A shell rotating shaft is arranged on the central axis of the inner side of the rotating shell, and the other end of the shell rotating shaft is fixed on the outer side of the fixed shell; and a data storage device is fixed on the inner side of the fixed shell.
As a preferred technical solution of the present invention, the data storage device includes a main rotating shaft, a storage disk mounting bracket, a USB interface, a storage disk slot, and a storage disk; the main rotating shaft is fixed on the inner side axis of the fixed shell; the outer side of the main rotating shaft is fixed with a storage disc mounting rack through a bearing, the storage disc mounting rack can freely rotate on the main rotating shaft, the lower end of one side of the storage disc mounting rack is provided with a USB interface, and the middle parts of the six sides are provided with storage disc slots; the storage disk can be fixed on the storage disk mounting frame through the storage disk slot.
Compared with the prior art, the beneficial effects of the utility model are that: the data storage certificate equipment based on the area chain is small in size and convenient to place, the storage disc mounting frame can rotate freely, the data storage disc can be replaced conveniently, and data needing to be backed up can be easily positioned; the data evidence storage device based on the area chain can be conveniently connected with required equipment through the USB interface, and a data storage disc with a proper storage space can be used as required.

Detailed Description
Example 1
As shown in fig. 1 to 3, a data storage device based on a local chain includes a rotating housing 1, a housing rotating shaft 2, a fixed housing 3, and a data storage device 4. A shell rotating shaft 2 is arranged on the central axis of the inner side of the rotating shell 1, and the other end of the shell rotating shaft 2 is fixed on the outer side of the fixed shell 3; a data storage device 4 is fixed on the inner side of the fixed shell 3.
As a preferred technical solution of the present invention, the data storage device 4 includes a main rotating shaft 401, a storage disk mounting bracket 402, a USB interface 403, a storage disk slot 404, and a storage disk 405; the main rotating shaft 401 is fixed on the inner side axis of the fixed shell 3; a storage disk mounting rack 402 is fixed on the outer side of the main rotating shaft 401 through a bearing, the storage disk mounting rack 402 can freely rotate on the main rotating shaft 401, a USB interface 403 is arranged at the lower end of one surface of the storage disk mounting rack 402, and storage disk slots 404 are formed in the middle of six surfaces; the storage tray 405 may be fixed to the storage tray mounting frame 402 through the storage tray insertion slot 404.
The utility model discloses the theory of operation: the data evidence storage device based on the area chain is connected with required equipment through a USB interface, and data can be written into a preset storage disk and can also be read from the data stored in the storage disk in advance. When the storage disc is replaced, the storage disc mounting frame can be rotated, the required storage disc can be dismounted or mounted according to requirements, and the dismounted storage disc is further stored and backed up. When the data evidence device is deposited to normal use based on regional chain, rotatory shell rotates and blocks fixed shell breach position completely, can protect the storage disc of inside, uses for a long time and prevents that the dust from falling into wherein.
The utility model relates to a circuit connection is the conventional means that technical staff adopted in this field, and accessible limited number of tests obtains the technological inspiration, belongs to the widely used prior art.
