An oil painting stand with multi-directional telescopic adjustment

technical field

The invention relates to the technical field of painting stands, in particular to an oil painting painting stand with multi-directional telescopic adjustment.

Background technique

An easel is a shelf used to place a drawing board when painting. At present, fine arts majors include oil painting, calligraphy, traditional Chinese painting, sketching, etc. The materials required for each direction are different, especially the supporting shelves required for operation are very different. Oil painting requires a tall shelf that can support the picture frame. The shelf allows a certain adjustment space to adapt to the change of the size of the picture frame; calligraphy and traditional Chinese painting require a relatively large horizontal desktop to complete the operation; when sketching, the drawing board needs to be tilted at a certain angle, and the area of the drawing board is limited. Need to also design a kind of painting frame for satisfying such requirement

For example, the patent No. CN201320070906.1 discloses a multifunctional painting easel. The invention solves the technical problem that the easel has a single function. The upper part of the left outrigger and the right outrigger of the easel of the present invention are fixedly connected by the upper cross brace, and the lower part of the left outrigger and the right outrigger is fixedly connected by the lower cross brace; The top is fixed on the upper cross brace by a hinge, and there is a long hole in the upper part of the supporting leg. One end of the supporting bar is hinged with the upper part of the column, and the other end of the supporting bar is fixed in the long hole of the supporting leg by bolts. Set through holes, the supporting plate is fixed in several through holes of the column through bolts, the drawing board support rod is fixed on the supporting plate through bolts, the right outrigger is connected with the bucket fixing device through a telescopic rod, and the middle part of the left outrigger is provided with a paintbrush placement plate. Several jacks are evenly distributed on the paintbrush placement board. The invention is used for painting.

In the existing easels, the two main support rods on the front side are usually supported in a figure-eight shape, which occupies a large area, and the bottom support plate of the skateboard is mostly a fixed cross-bracing type, which cannot be rotated and contracted, resulting in a large idle volume of the easel. It is inconvenient to store and transfer. In addition, the upper and lower splints of the drawing board are mostly installed with split bodies. When adjusting the height of the drawing board, the upper and lower splints need to be loosened and disassembled sequentially.
