Description

Technical Field

[0001] The utility model relates to the technical field of hand-painted boards, in particular to a multifunctional hand-painted board for field measured profiles. Background Art

[0002] Field measured profile is a basic survey method in geological work. Field measurements are carried out in a certain direction in the field, and the data is obtained through calculation and the measured profile is drawn. Generally, field measured profiles are used to understand the thickness of the strata, geological structure and rock characteristics in the survey area. When measuring profiles, workers need to complete sketches in the field, which requires the use of a drawing board.

[0003] However, most people now use the most basic drawing board. Under the influence of complex geological conditions in the field, it is difficult for draftsmen to find a suitable place to fix or place the drawing board, which often affects work efficiency. Secondly, using the most basic drawing board requires fixing the drawings on the board with tools such as transparent tape, which not only reduces the effective use area of ​​the drawings but also damages the drawings.

[0004] In order to solve the above problems, a multifunctional outdoor sketching stand with announcement number CN220298206U is provided, which includes a bottom supporting plate body, and long strip placing frames are symmetrically arranged on both sides of the bottom supporting plate body, one end of the long strip placing frame is rotatably provided with an external tube body, the upper side of the external tube body is provided with a long strip notch, the lower side of the external tube body is provided with an auxiliary sliding long strip through hole, the inner sliding of the external tube body is provided with a sliding tube body, an L-shaped sliding strip is arranged on the sliding tube body, and an auxiliary connecting strip is arranged between the shorter parts of the L-shaped sliding strips on both sides; a sliding block is arranged at the lower part of the sliding tube body, and the sliding block and the auxiliary sliding long strip through hole are slidably matched; a friction gasket is arranged on the long strip placing frame for fixing the external tube body.

[0005] Although the utility model can place the drawing board on the symmetrically arranged L-shaped sliding bars, the long placement frame can only be kept level on the horizontal plane. However, under the complex terrain conditions in the field, it is not necessarily possible to find a nearly horizontal open space to place the sketching stand. It is not flexible enough and is not completely suitable for the drawing of measured profiles in the field, and has a small scope of application. Utility Model Content
