Description

Technical Field

[0001] The utility model relates to the technical field of drawing storage, in particular to a portable drawing storage tube for surveying and mapping geographic information. Background Art

[0002] Surveying and mapping refers to the determination, collection and drawing of the shape, size, spatial position and attributes of natural geographical elements or artificial facilities on the surface. Surveying and mapping drawings are divided into paper drawings and electronic drawings. When storing paper drawings, in order to avoid creases, the drawings are rolled up and stored. When conducting geographic information surveying and mapping, since it is necessary to move the geographic information surveying and mapping, a portable drawing storage device will be used.

[0003] In order to facilitate the storage of drawings during geographic information surveying and mapping, the prior art has made many improvements to the drawing storage device, such as the patent with the publication number CN220483921U, which discloses a portable storage cylinder for drawings for surveying and mapping geographic information. The utility model includes a cylinder, a top cover and two fixed plates. A limited hole is provided on the outer cylindrical surface of the middle part of the cylinder, a clamping block is provided in the middle of the bottom end of the top cover, and the clamping block is movably clamped on the inner wall of the top of the cylinder, a center rod is provided inside the cylinder, a sleeve is rotatably connected to the middle of the bottom end of the clamping block, and the sleeve is slidably sleeved on the outer cylindrical surface of the center rod, a handle is provided on one side of the cylinder, a ruler spring is provided on the outer cylindrical surface of the middle part of the sleeve, and a fixed plate is provided at one end of the ruler spring. The utility model opens a limited hole inside the cylinder so that the drawings can be pulled out and unfolded, which is convenient for one person to unfold and view the drawings. By setting a center rod inside the cylinder, and using the ruler spring, sleeve and fixed plate in combination, it is convenient to automatically store the unfolded drawings.

[0004] The above patent has obvious beneficial effects, but still has the following shortcomings in actual operation:

[0005] In the above-mentioned comparative documents, the drawings are inserted into the cylinder, and when the drawings need to be viewed, the drawings are pulled out through the limit hole position. However, in the existing geographic information surveying and mapping, there are a large number of drawings, and most of the drawings are rolled into a roll and stored inside the cylinder. When the number of drawings is too large, the outer diameter of the rolled drawings must be larger than the inner diameter of the cylinder. It is troublesome for surveying and mapping personnel to insert the rolled drawings into the cylinder, and the drawings may be damaged. In addition, the sizes of existing drawings are different. When the length of the rolled drawings is less than the length of the cylinder, the rolled drawings are scattered in the cylinder, and the drawings are against the inner wall of the cylinder. It is troublesome to take out the drawings in the cylinder. Therefore, this field is in urgent need of improvement in the portable storage cylinder for drawings for surveying and mapping geographic information, so as to solve the defects of the prior art.
