Description

telescopic drawing table

technical field

The utility model relates to a telescopic drawing table, in particular to a telescopic, lifting and folding drawing table. the

Background technique

With the development of the economy and the continuous improvement of production levels, the machinery industry has higher and higher requirements for mechanical professionals. Not only should they have a solid theoretical foundation, but they also need to have skilled technical application capabilities and strong innovation capabilities. Therefore, innovative practice teaching is a key link in the process of talent training, and an important platform for integrating theory with practice and cultivating students' innovative consciousness and practical ability. the

As an auxiliary tool commonly used in the teaching of machinery, art, architecture and garden drawing, the drawing table is frequently used in the teaching of related majors in related universities. At present, the design of the drawing table still stays at the stage of traditional fixed-point drawing, which cannot meet the different usage requirements of various drawers. The drawing desks in the market can be divided into traditional drawing desks, desktop drawing desks and lift-adjustable drawing desks. The market prices of these kinds of drawing tables range from several hundred to several thousand yuan depending on the materials used and the performance of the table itself. In terms of performance, these types of drawing tables have their own advantages and disadvantages. The traditional drafting table is a bulky and bulky drafting stand with a single function. The height of the table body is fixed, which cannot meet the comfort scale requirements of different heights of the drawers. For example, the utility model whose authorized announcement number is CN203493075U belongs to this category. The advantage of the desktop drawing table is that it has a simple and generous appearance and is easy to carry. However, the drawing board itself needs to be attached to the support of the desktop to play the role of drawing, and the effect of the separated support is not stable enough, which only solves the most basic requirements of drawing. For example, the utility model whose authorized announcement number is CN201958147U belongs to this category. At present, the drawing table with the most comprehensive functions is the lifting adjustable drawing table. The biggest problem is that its horizontal and vertical dimensions cannot be adjusted, and the requirements for different types of drawing boards cannot be conveniently placed according to the needs of actual teaching. For example, the utility model whose authorization announcement number is CN202233865U belongs to this category. the
