Description

Technical Field

[0001] The invention relates to the technical field of engineering drawing storage and archiving, and in particular to a paper engineering drawing storage cabinet. Background Art

[0002] Architectural engineering drawings are the technical basis and technical data for the construction of engineering projects. Architectural engineering drawings include scheme design drawings, various construction drawings and project completion drawings. Due to the different task requirements at each stage of engineering construction, the content, depth and method of expression of various drawings are also different. Scheme design drawings are mainly for soliciting opinions from construction units and for approval by relevant leading departments. Construction drawings are the basis for construction units to organize construction. Completion drawings are drawings drawn according to actual construction conditions after the completion of the project. The above drawings should still be kept as technical files after the project is completed so that they can be consulted at any time when needed.

[0003] Engineering drawings are generally large in area. If they are folded for storage, the creases produced at the folds will cause the corresponding positions of the drawings to be blurred, and the life of the drawings will also be affected. Therefore, drawings can generally only be unfolded for storage (such as the technical solution disclosed in the patent with application number 202222949822.7, which unfolds the drawings with a clip, clamps the top edge of the drawings, and then hangs and fixes them in the cabinet), but the unfolded storage method causes it to occupy a larger area, resulting in a smaller number of drawings that can be stored in the cabinet, and the unfolded drawings are hung by a clamp, and when the unfolded drawings are hung by a clamp, the staff will directly separate the clamp for hanging the drawings from the cabinet by touching the drawings when taking and placing the drawings, which will cause pulling between the drawings and the clamp, resulting in pulling at the connection between the drawings and the clamp, and there is a possibility of tearing the drawings; or they can be rolled and stored (such as the technical solution disclosed in the patent with application number 202120581419.6, which rolls the drawings into rolls or tubes and stores them in a drawing tube, and then stores them in the cabinet), and after being rolled into rolls or tubes and stored in the drawing tube, since the drawing tubes in the cabinet are relatively limited, the cabinet has a small amount of drawings to store, which leads to a very low storage efficiency of the cabinet. In addition, there are some structures of drawing storage cabinets on the market, such as the technical solution disclosed in the patent with application number 202121725788.4, which also fixes the drawings after winding them. However, in order to facilitate observation, the drawings of this technical solution can be unfolded at the same time when the drawer board is pulled out. However, in order to achieve this technical effect, each drawer board can only be used to store one drawing, which also leads to a small number of drawings that can be stored in the cabinet. Another technical problem is that the connection and fixing operation of the drawings and the related structures of the drawer boards is relatively complicated, and the drawings themselves need to be perforated before they can be stored and fixed, which is destructive to the drawings themselves.

[0004] With the development of urban construction, various engineering drawings are increasing. Therefore, how to provide a storage cabinet that can improve the storage efficiency of drawings and facilitate the placement and retrieval of drawings without affecting the drawings is a technical problem that technical personnel in this field need to solve urgently.

[0005] In addition, engineering drawings have certain requirements for the storage environment. If the drawings are stored in a low temperature and low humidity environment, the drawings will become brittle, and then the drawings will be easily cracked and damaged; if the drawings are stored in a high temperature and high humidity environment, the drawings will be damaged by insects. Therefore, the applicant also needs to solve this technical problem at the same time. Summary of the invention
