Compact shelf with crank type door shafts

Abstract

The invention relates to a compact shelf with crank type door shafts. The compact shelf with the crank type door shafts comprises a cabinet body, two cabinet doors and a plurality of crank type door shafts, first shaft holes are formed on an upper crossbeam and a lower crossbeam of the cabinet body; rectangular crank grooves are formed on the top surface and the bottom surface of the cabinet doors; second shaft holes are formed on the bottom surfaces of the crank grooves; and one end of each crank type door shaft is inserted into the first shaft hole and the other end of each crank type door shaft is inserted into the second shaft hole. In the compact shelf with the crank type door shafts, the door shafts are designed into crank types; in the process of opening each cabinet door by 0 to 90 degrees, the cabinet door rotates by using one end, inserted into the crossbeam of the door frame, of the crank type door shaft as an axial center; and in the process of opening each cabinet door by90 to 180 degrees, the cabinet door rotates by using one end, inserted into the cabinet door, of the crank type door shaft as an axial center, so that complexity of the door shaft structure is not increased, opening angle of the cabinet door is enlarged, the problems that a file cabinet is damaged easily and people are injured when the cabinet doors are opened to 90 to 100 degrees are solved, andthe service life of the file cabinet is prolonged.

Description

technical field [0001] The invention belongs to the technical field of file management devices, in particular to a compact shelf equipped with a crank type door shaft. Background technique [0002] At present, most of the commonly used compact shelves are iron cabinets, which are mainly composed of a cubic cabinet body, at least one cabinet door installed at the front opening of the cabinet body, and installed between the upper and lower ends of one side of the cabinet door and the upper and lower beams of the cabinet door frame. Composed of multiple door shafts between. But there is following problem in this filing cabinet of prior art: because above-mentioned door shaft mostly is straight stick shaft, so cabinet door can only be outwardly opened to about 90~100 degrees, at this moment if continue to apply on the other side of cabinet door At this time, the force of opening outwards will take the vertical side of the door shaft as the fulcrum to form a moment, so that the ...

AI Technical Summary

Problems solved by technology

But there is following problem in this filing cabinet of prior art: because above-mentioned door shaft mostly is straight stick shaft, so cabinet door can only be outwardly opened to about 90~100 degrees, at this moment if continue to apply on the other side of cabinet door At this time, the force of opening outwards will take the vertical side of the door shaft as the fulcrum to form a moment, so that the force of opening the door will be magnified by 40 to 50 times and then added to the door shaft. The door frame beam of the shaft is damaged or even falls off due to excessive force

In addition, when the cabinet door is opened at 90-100 degrees, it is easy to collide and hurt people, so it is very unsafe.
