Special file box for file storage of public institutions

Abstract

The invention discloses a special file box for file storage of public institutions, relates to the technical field of file storage, and solves the problems that an existing file box does not have a convenient depressurization storage function, and depressurization cannot be provided for files through an auxiliary structure while the files are closed. The special file box for file storage of the public institutions comprises a main box body and a pulling plate, wherein the main box body is of a rectangular structure, and the top and the rear side of the main box body are of opening structures; an air inlet is formed in the middle of the top of the main box; and a main body of the pulling plate is of a rectangular plate structure, and the two sides of the pulling plate are wider than the two sides of the main box body. By arranging an air frame, a depressurization function is provided for the file box, the storage time of files can be prolonged through depressurization, and the files are prevented from being humid and corroded and are prevented from being in contact with the outside; and an air connecting device is unsealed through an air passing hole, the air frame communicates with the main box body, air in the main box body moves towards the interior of the air frame, the air pressure in the main box body is reduced by one third, and depressurization storage of the files is achieved.

Description

technical field [0001] The invention relates to the technical field of file storage, in particular to a special file box for file storage of public institutions. Background technique [0002] Archives refer to various forms of original records with preservation value directly formed by people in various social activities, especially when working in public institutions, the requirements for archives are relatively high, and it is necessary to use better-preserved records in the later verification Files generally require file boxes that can be stored for a long time.
