[0026] Example

[0027] Reference Figure 1-Figure 3, which is an embodiment of the present invention, provides a drawing board for mechanical drawing, including: a drawing board body unit 100, a tilt angle adjustment unit 200 and a storage unit 300.

[0028] The drawing board unit 100 includes a drawing board 101 and a handle 102 fixedly arranged on the top of the drawing board 101;

[0029] Secondly, the tilt angle adjustment unit 200 includes a hollow cylinder 201 fixedly arranged on the back side of the drawing board 101 and a rotating rod 202 rotatably connected to the hollow cylinder 201. A reinforcing block 207 is fixedly arranged at the center of the hollow cylinder 201, and the rotating rod 202 passes through the reinforcing block 207 and is rotatably connected to the reinforcing block 207. The arrangement of the reinforcing block 207 improves the connection stability between the rotating rod 202 and the hollow cylinder 201. A support frame 203 is fixedly sleeved at both ends of the rotating rod 202. The support frame 203 is arranged in a U shape, and the width of the support frame 203 is one-half to two-thirds of the length of the drawing board 101. In this way, The supporting effect of the support frame 203 on the drawing board 101 is guaranteed. The two ends of the side wall of the hollow cylinder 201 are threadedly connected with symmetrically positioned adjustment bolts 204. Each adjustment bolt 204 is inserted into the hollow cylinder 201 and rotatably connected to a tightening cover 205. The tightening cover 205 is fixedly connected to the inner wall of the hollow cylinder 201 through a symmetrically positioned guide telescopic rod 206. The tightening cover 205 is arranged in an arc shape, and a grid-patterned silicone pad is fixedly provided on the inner wall of the tightening cover 205. The provision of the grid-patterned silicone pad increases the friction between the tightening cover 205 and the side wall of the rotating rod 202, thereby improving the pressing and positioning effect of the tightening cover 205 on the rotating rod 202;

[0030] Furthermore, the storage unit 300 is used to store tools and drawings used in the mechanical drawing process.

[0031] The storage unit 300 includes a drawing storage slot 301 and a tool storage slot 303 opened on one side of the drawing board 101. A plurality of evenly distributed winding rods 302 are fixedly installed in the drawing storage slot 301. A corresponding first rubber stopper 304 is provided at the opening of the drawing storage slot 301, and a second rubber stopper 305 is provided at the opening of the tool storage slot 303.

[0032] A plurality of evenly distributed telescopic columns 103 are fixedly provided at the front edge of the drawing board 101. A pressure plate 105 is fixedly provided at one end of the telescopic columns 103 away from the drawing board 101. A spring 104 is sleeved on the telescopic columns 103. The two ends of the spring 104 are fixedly connected to the pressure plate 105 and the drawing board 101 respectively. A rubber pad is fixedly provided on the side of the pressure plate 105 close to the drawing board 101.

[0033] During use, the rotating rod 202 drives the support frame 203 to rotate relative to the hollow cylinder 201, thereby adjusting the inclination angle of the drawing board 101. When the inclination angle of the drawing board 101 is adjusted, tighten the adjusting bolt 204. Under the guidance of the guide telescopic rod 206, the pressing cover 205 can press the rotating rod 202, thereby fixing the support frame 203. Then, a blank drawing is laid on the front of the drawing board 101, and the corresponding pressing plate 105 is loosened to press the edges and corners of the drawing in turn to achieve effective positioning of the drawing and avoid movement of the drawing during mechanical drawing. After drawing is completed, the drawn drawing can be wound on the corresponding winding rod 302 in turn, and the tools used in the drawing process can be placed in the tool storage cavity 303 to achieve storage of tools and drawings.

[0034] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, and all of these should be included in the scope of the claims of the present invention.
