Composition of dense cabinets
The dense cabinet is mainly composed of tracks, bases, columns (plate type), shelves, hanging boards, side support plates, back support plates, top plates, dustproof plates, guard plates, door panels, transmission mechanisms, anti-dumping, shockproof, dustproof, rat-proof, brakes, buffers, catalog cards and transmission devices, and sealing devices
Formation: (1) The track includes a ground rail and a guide rail. (2) The frame body includes a column, a hanging board, a shelf, a separator rod, and a dust board. Column: the vertical column that supports the whole shelf; hanging board: placed between the shelf and the shelf, playing the role of supporting and fixing; shelf: the flat board for storing archival materials; separator: used to separate the middle of the materials stored on both sides to prevent chaos; dust plate: placed on the top of the shelf, mainly used to prevent dust.

The diameter of the spindle and bearing is φ20mm, the high-quality manganese steel material GB3882-87 of the 45# steel factory No. 5, the Z390504 outer spherical bearing with seat, and the short shaft pipe sleeve connection transmission, with reliable center straightness, the frame body moves smoothly, lightly and naturally. (4) Chassis: It is mainly used to support the base of the frame body. (5) sealing device: prevent damage caused by impact when the dense cabinet is closed, and at the same time can also reduce the noise generated by the impact when the frame body is opened and closed, and play the role of anti-collision, dust-proof, moisture-proof, noise-proof and rodent-proof; (6) panel: including the inner side panel, the outer side panel, and the door panel (7) the top plate: the top of the dense cabinet shelf, the top of each cabinet is equipped with a dust-proof device to prevent dust from falling into the top and bottom frame of the cabinet in the cabinet: each group of movable single-sided cabinet tops are equipped with an anti-falling device.
