Embodiment

[0024] A mechanical drawing table whose height and slope can be adjusted continuously, its structure is as follows figure 1 As shown, it includes a desktop 1, an upper bracket 2 connected to the bottom of the desktop 1, and a lower bracket 3 supported on the ground. The desktop is provided with a movable end, and also includes a height adjustment component and a slope adjustment component.

[0025] The height adjustment assembly includes a connecting rod 4, a height adjustment motor 5, a height adjustment screw 6 and a rotating thrust member. The connecting rod 4 is two symmetrical X-shaped connecting rods connecting the upper bracket 2 and the lower bracket 3. The adjustment motor 5 drives the rotary thrust piece through the height adjustment screw 6. The rotary thrust piece includes a left-handed thrust piece 7 and a right-handed thrust piece 8 arranged in parallel to each other. Pushing the middle out gradually straightens the folded link to adjust the height. The height a...

Abstract

The invention relates to a mechanical drawing desk with continuously adjustable height and slope. The mechanical drawing desk comprises a desktop, an upper support connected below the desktop and a lower support supported on the ground; a moving end is arranged at the desktop; the mechanical drawing desk also comprises a height regulating assembly and a slope regulating assembly; the height regulating assembly comprises a connection rod, a height regulating motor, a height regulating lead screw and rotary thrust parts; the slope regulating assembly comprises a threaded seamless pipe, a slope regulating lead screw and a slope regulating motor which are connected to the moving end of the desktop in sequence. Compared with the prior art, the mechanical drawing desk with the continuously adjustable height and slope has the advantages of high pressure bearing capacity, stable usage, capability of conveniently continuously adjusting height and slope and the like.

Description

technical field [0001] The invention belongs to the technical field of teaching stationery, and in particular relates to a mechanical drawing table whose height and slope can be continuously adjusted. Background technique [0002] There are electric and non-electric types of liftable tables currently on the market, and there are many kinds of materials. Electric desks are generally driven by high-voltage 220v, which is not suitable for classrooms and has limited load-bearing. Most of the non-electric tables do not need a motor or a compressor. It is very labor-intensive to adjust the mechanical device, hydraulic rod, and air rod by manpower, and more often the height is adjusted through a limited number of gears, and the adjustment ability is limited. And whether it is electric or non-electric, the slope cannot be adjusted. [0003] The Chinese patent application number 201020217322.9 discloses a height-adjustable table, including a table top and table legs. The table legs...
