Problems solved by technology

[0002] Drawing equipment is a device used to assist designers in drawing drawings. In order to facilitate drawing personnel to draw, the equipment adopts an adjustable angle to adjust the board surface. At the same time, in order to facilitate design in different venues, most of them use portable drawing equipment. However, when mathematically modeling the construction scope at the construction site, due to the sand and gravel on the ground of the construction site, there will be a layer of gravel in the middle of the support of the drawing equipment on the cement floor of the construction site, making it difficult for the drawing equipment to come into direct contact with the cement floor. During the drawing process, the drawing equipment is easy to move, which brings inconvenience to the drawing process, and at the same time, it is easy to cause the drawing equipment to fall, reducing the drawing efficiency

Embodiment 1

[0028] as attached figure 1 to attach Figure 5 Shown:

[0029] The invention provides a drawing device for mathematical modeling, the structure of which includes a support frame 1, a drawing board 2, and an illumination lamp 3, the upper end of the support frame 1 is screwed to the lower side of the illumination lamp 3, and the lower side of the drawing board 2 The middle part of the support frame 1 is movable and engaged. The support frame 1 includes a support leg 11, a cross frame 12, and a fixing clip 13. The middle part of the support leg 11 is movably engaged with the rear side of the cross frame 12. The upper end of the leg 11 is an interference fit.

[0030] Wherein, the support leg 11 includes a contact head 111, a connecting block 112, and a telescopic rod 113, the upper end of the contact head 111 is axially connected to the lower end of the telescopic rod 113, and the connecting block 112 is nested and connected with the outer middle part of the telescopic rod 11...

Abstract

The invention discloses a drawing device for mathematical modeling. The structure includes a support frame, a drawing board, and an illumination lamp. The upper end of the support frame is threadedly connected with the lower side of the illumination lamp. Including supporting legs, cross frames, and fixing clips, they are placed on the concrete floor through the supporting frame, and then squeezed by the suction cup fixed by the fixed block. Under the pull, the internal pressure is formed, the equipment is adsorbed and fixed on the ground, the fixing ability of the equipment is improved, and the equipment is prevented from moving. After the threaded rod is under pressure, it moves downward to squeeze the rotator. The threaded torsion of the rod rotates, and the throwing arm is thrown out through inertia to clean the gravel on the underside of the suction cup, remove the gravel on the ground, prevent the suction cup from contacting the gravel on the ground, and improve the gripping ability on the ground.
