Technical Field

[0001] The utility model relates to the technical field of drawing tools, in particular to a drawing device for design. Background Art

[0002] During the construction process, architects usually need to draw more drawings according to the specific conditions of the on-site construction in order to carry out subsequent construction. Then, in the process of the architect drawing the drawings by hand, a drawing board is needed to keep the drawings tilted so that the designer can draw better and faster.

[0003] At present, in the process of architectural design, architects still need to frequently refer to previously drawn drawings for comparative drawing. Due to the limited bearing area of ​​existing drawing boards, during the comparative drawing process, staff can only hold the previous drawings with one hand and draw with the other hand, which is inconvenient for architects to draw. Therefore, we propose a design drawing device to solve the above problem. Utility Model Content

DETAILED DESCRIPTION

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0022] Reference Figure 1-4A drawing device for design includes a drawing board 1. The lower side of the drawing board 1 is connected to a support plate 14 by a hinge. A limit frame 15 is hinged on the back of the drawing board 1. Positioning grooves that are compatible with the limit frame 15 are equidistantly provided inside the support plate 14. The limit frame 15 is set as a U-shaped structure. Since it is hinged to the drawing board 1 and multiple groups of positioning grooves are opened, the support angle of the drawing board 1 can be adjusted. This is a prior art and will not be described in detail here. A receiving groove 2 is opened inside the drawing board 1, and an extension plate 3 is inserted into the receiving groove 2. By opening the receiving groove 2, the extension plate 3 can be accommodated. By setting the extension plate 3, the previous drawing can be supported.

[0023] Further, see Figure 2 and Figure 3 It can be known that a fixing block 6 is connected to the outer side of the extension plate 3, and a guide rod 9 is inserted into the interior of the fixing block 6, and both ends of the guide rod 9 are connected to the inner wall of the extension plate 3, and the guide rod 9 is arranged as an L-shaped structure. When in use, the extension plate 3 in the pulling process can be guided by the mutual cooperation of the fixing block 6 and the guide rod 9. Since the guide rod 9 is arranged in an L-shape, the fixing block 6 can be limited to prevent the extension plate 3 from being completely pulled out from the inside of the accommodating groove 2, thereby preventing the extension plate 3 from falling from the inside of the accommodating groove 2 during the supporting process.

[0024] Further, see Figure 2 and Figure 3 It can be known that connecting rods 4 are distributed on the side of the drawing board 1, and the inner side of the connecting rods 4 is symmetrically connected to the limiting rods 5, the limiting rods 5 penetrate the inner wall of the drawing board 1 and extend into the extension plate 3, and the interior of the fixing block 6 is provided with limiting grooves adapted to the limiting rods 5. By setting two groups of limiting rods 5, the extension plate 3 that is pulled out and pushed in can be limited and fixed to prevent the extension plate 3 from moving easily during transportation or use.

[0025] Further, see Figure 1 and Figure 4 It can be known that the side wall of the extension plate 3 is connected to the pull plate 10, and a groove 11 is opened at the center position of the pull plate 10. Through the cooperation between the pull plate 10 and the groove 11, it is convenient for the staff to pull the extension plate 3, and the right side opening of the accommodating groove 2 can be sealed after use.

[0026] Further, see Figure 1 and Figure 2 It can be known that a pen slot 12 is provided inside the extension plate 3, and the pen slots 12 are horizontally and equidistantly distributed on the upper surface of the extension plate 3. The length of the pen slot 12 is always greater than the length of the paintbrush. By opening the pen slot 12, paintbrushes of various colors can be stored and transported together with the drawing board 1, so that the staff can directly use them when drawing.

[0027] Further, see Figure 4 It can be known that the inner wall of the pen slot 12 is symmetrically connected with a rubber plate 13, and the rubber plate 13 is set to an inclined structure. The rubber plate 13 is set with rubber material and the rubber plate 13 is inclined, so the fixing effect of the paintbrush can be improved.

[0028] Further, see Figure 3 It can be known that the inner side of the connecting rod 4 is connected to the linkage rod 8, the inner wall of the drawing board 1 is provided with a groove hole adapted to the linkage rod 8, and the inner wall of the groove hole is connected to a spring 7, and the other end of the spring 7 is fixedly connected to the linkage rod 8. Through the cooperation between the linkage rod 8 and the spring 7, the fixed block 6 can be moved to a position corresponding to the fixed block 6, and the limiting rod 5 can be automatically reset and engaged by the elastic force of the spring 7, and the tightness of the limiting rod 5 engaged in the fixed block 6 can be effectively ensured.

[0029] Working principle: When the utility model is in use, the staff can first place the device at a suitable position on the desktop, and then lift the receiving slot 2 to rotate it to a suitable angle, and then the support plate 14 hinged on the back of the receiving slot 2 can be engaged with the corresponding positioning slot inside the limiting frame 15 to achieve the limiting fixation of the receiving slot 2, and then the staff can use clips or thumbtacks to fix the drawings on the receiving slot 2 for drawing. When it is necessary to draw a comparison, the staff can first pull the connecting rod 4 to keep it away from the drawing board 1, so that the left limiting rod 5 can be pulled out from the inside of the fixing block 6 to release the limiting of the extension plate 3, and then the staff can By pulling the pull plate 10, the extension plate 3 can be drawn out from the interior of the accommodating groove 2. When the extension plate 3 is completely pulled out, the position of the fixing block 6 corresponds to the position of the right-side limiting rod 5. At this time, the staff can stop pulling the connecting rod 4, so that the limiting rod 5 is reset by the elastic force of the spring 7 and is engaged with the interior of the fixing block 6 to limit the extension plate 3. Then the staff can use tools such as clips or thumbtacks to fix the previous drawings on the extension plate 3 for support. After use, the staff can pull the connecting rod 4 again to store the extension plate 3 into the interior of the accommodating groove 2 for subsequent transportation. The above is the entire working principle of the utility model.
