Easel for art teaching

Abstract

The invention discloses an easel for art teaching. The easel comprises a telescopic frame mounted on a base, wherein a mounting frame is fixedly mounted at the upper end of the telescopic frame; a drawing board is rotationally connected to the upper end of the mounting frame; a mounting rod I is rotationally connected to the mounting frame; a connecting rod is in threaded connection with the mounting rod I; a mounting rod II is rotationally connected to the upper end of the connecting rod; and the upper end of the mounting rod II is rotationally connected to the drawing board. The easel has the advantages that the angle adjustment operation of the drawing board is simple and convenient, and the fixing operation is automatically realized after adjustment, so that the angle of the drawing board is prevented from being changed in the drawing process; and the distance between the drawing board and a drawer can be adjusted by applying an acting force to the telescopic frame by hands, and the telescopic frame cannot move under the action of a balancing weight after the acting force applied to the telescopic frame is removed, so that the position of the drawing board cannot be changed inthe drawing process.

Description

technical field [0001] The invention relates to an easel, in particular to an easel for art teaching. Background technique [0002] After searching, the authorized invention patent document with the patent number CN106274255B discloses an easel for art teaching, which includes a drawing board, a first telescopic rod and a bottom plate. , a mirror is fixedly installed on both sides of the drawing board. [0003] There are also the following two weak points in the above-mentioned teaching easel: [0004] 1. There is a rotating connection between the drawing board and the first telescopic rod, but there is no added support and fixing structure between the two. When turning a certain angle to paint, a little force can make the drawing board rotate, which leads to painting failure . [0005] 2. By pulling the first telescopic rod back and forth with the handle, the second telescopic rod can be extended or retracted, so as to determine the distance between the person and the dr...

AI Technical Summary

Problems solved by technology

[0004] 1. There is a rotating connection between the drawing board and the first telescopic rod, but there is no added support and fixing structure between the two. When turning a certain angle to paint, a little force can make the drawing board rotate, which leads to painting failure

[0005] 2. By pulling the first telescopic rod back and forth with the handle, the second telescopic rod can be extended or retracted, so as to determine the distance between the person and the drawing board, but there is no fixed structure after the movement, and in order to make the pulling easier , install universal wheels at the lower end of the first telescopic rod, but this way makes it easier to retract the first telescopic rod into the second telescopic rod during the painting process
