Student drawing board and bracket with universal rotating adjusting capacity

Abstract

The invention relates to the technical field of teaching aids for students, in particular to a student drawing board and bracket with the ability to adjust the universal rotation. There is a groove inside the side of the base, one end of the weight plate is embedded in the groove, and a weight is installed on the upper end. , the sleeve is installed on the base, the vertical rod is provided with a sliding tube, the top is provided with a hinge shaft, and the back of the drawing board is provided with two cross bars. The damping shaft on the sliding cylinder is connected by two struts, and the struts are hinged through the hinge shaft. The end of the Y-shaped bracket connected to the cross bar and the end of the strut are equipped with plug joints, and the hinge shaft is equipped with Fastening bolts are provided on the tightener, the sleeve and the sliding cylinder. The structure design of the present invention is reasonable, and adopts telescopic support structure to install brackets and poles, and the drawing board is installed on the brackets and poles. Through the combined connection structure of hinge shaft, damping shaft and plug joint, it can realize freedom in any height, direction and angle. Adjustment, simple operation, stable and reliable, suitable for students to use.

Description

technical field [0001] The invention relates to the technical field of student teaching aids, in particular to a student drawing board and a bracket with universal rotation adjustment capability. Background technique [0002] Drawing board is a kind of drawing tool used by draftsmen to paste drawing paper and successfully complete drawing operations. It is a teaching tool used in the field of art creation and engineering drawing. It has the characteristics of simplicity, efficiency and practicality in drawing. However, the current drawing board tables are generally fixed desktops, or have a certain inclination angle, and the angle of the desktop board and the rotating desktop cannot be adjusted according to actual needs, which affects the drawing efficiency. [0003] The announcement number is CN204930785U, which is a kind of universal rotating drawing board table. The angle adjustment and rotation functions of the table board are realized by the column sleeve arranged on th...

Problems solved by technology

However, judging from the structure of the embodiment, it is unrealistic for the brake and the spherical rotary joint to fix the column sleeve and the drawing board through static friction. The inclination angle can form far beyond the static friction between ordinary materials, its structure is very easy to overturn, and the inclination angle range of the drawing board is severely limited
