[0032] See also Figure 1-4 The utility model provides a technical solution: a graphic design drawing device, comprising a first pressing plate 1 and a second pressing plate both of which are L-shaped structures, wherein the first pressing plate 1 and the second pressing plate are connected to form a rectangular frame structure for applying pressure to the edge of the drawing paper;

[0033] The second pressing plate includes a first straight plate 2 and a second straight plate 3. The bottom of the first straight plate 2 is rotatably connected to a first pressing roller 4, and the first pressing roller 4 protrudes from the bottom surface of the first straight plate 2. The bottom of the second straight plate 3 is rotatably connected to a second pressing roller 5, and the second pressing roller 5 protrudes from the bottom surface of the second straight plate 3.

[0034] The bottoms of the first pressing roller 4 and the second pressing roller 5 are located on the same plane as the bottom surface of the first pressing plate 1 .

[0035] The first pressing roller 4 and the second pressing roller 5 are rotatably mounted on the bottom of the first straight plate 2 and the second straight plate 3, respectively. The first pressing roller 4 and the second pressing roller 5 can be moved to rotate on the first pressing roller 4 and the second pressing roller 5, respectively. The first pressing roller 4 and the second pressing roller 5 protrude from the bottom surfaces of the first straight plate 2 and the second straight plate 3, respectively, and are located on the same plane as the bottom surface of the first pressing plate 1;

[0036] When in use, first lay the drawing paper on the table, and then place the rectangular frame structure composed of the first pressing plate 1 and the second pressing plate on the drawing paper. Since the first pressing roller 4, the second pressing roller 5 and the bottom surface of the first pressing plate 1 are located on the same plane, the first pressing roller 4, the second pressing roller 5 and the first pressing plate 1 will press the four sides of the drawing paper respectively, and fix the four sides of the drawing paper at one time. By moving the first pressing roller 4 and the second pressing roller 5, the bottom of the first pressing roller 4 or the second pressing roller 5 is rotated from the inner side of the rectangular frame to the outer side, that is, the adjacent two sides of the drawing paper can be squeezed and pushed outward, and the part of the drawing paper located in the rectangular frame is pulled to keep it flat. After being pulled and fixed, the first pressing roller 4 and the second pressing roller 5 will remain in a relatively fixed state under the action of the gravity of the rectangular frame, which can keep the drawing paper in a tensioned state to a certain extent.

[0037] In order to increase the friction between the first pressing roller 4 and the second pressing roller 5 and the drawing paper, the first pressing roller 4 and the second pressing roller 5 can both be made of rubber material.

[0038] In this embodiment, a first mounting groove for mounting the first pressing roller 4 is formed on the first straight plate 2. A first rotating shaft 6 runs through the first straight plate 2 along its length. The first rotating shaft 6 is rotatably connected to the first straight plate 2. The first pressing roller 4 is sleeved on the first rotating shaft 6.

[0039] A second mounting groove for mounting the second pressing roller 5 is provided on the second straight plate 3 . A second rotating shaft 7 passes through the second straight plate 3 along its length. The second rotating shaft 7 is rotatably connected to the second straight plate 3 , and the second pressing roller 5 is sleeved on the second rotating shaft 7 .

[0040] The first mounting groove and the second mounting groove serve as mounting and accommodating spaces for the first pressure roller 4 and the second pressure roller 5 respectively. The first rotating shaft 6 and the second rotating shaft 7 serve as supporting structures for the first pressure roller 4 and the second pressure roller 5 respectively, and can also serve as force transmission structures, that is, by rotating the first rotating shaft 6 or the second rotating shaft 7, the first pressure roller 4 or the second pressure roller 5 can also be driven to rotate.

[0041] In this embodiment, one end of the first rotating shaft 6 extends out of the first straight plate 2 and is connected to the first knob 8 ; one end of the second rotating shaft 7 extends out of the second straight plate 3 and is connected to the second knob 9 .

[0042] The first knob 8 and the second knob 9 will serve as force-applying parts respectively. The operator can act on the first knob 8 or the second knob 9 with bare hands or using tools such as wrenches to drive the first rotating shaft 6 or the second rotating shaft 7 to rotate, and ultimately push the first pressing roller 4 or the second pressing roller 5 to rotate.

[0043] In this embodiment, a plurality of grooves 10 are formed on the wheel surfaces of the first pressing roller 4 and the second pressing roller 5 . The grooves 10 are spirally extended along the axial direction of the first pressing roller 4 or the second pressing roller 5 .

[0044] By providing the spiral groove 10 , the friction between the first pressing roller 4 or the second pressing roller 5 and the drawing paper can be effectively increased, which is beneficial for pulling the drawing paper.

[0045] In this embodiment, a plurality of the first pressing rollers 4 and the second pressing rollers 5 are provided, and the cross sections of the first rotating shaft 6 and the second rotating shaft 7 are both regular polygons;

[0046] The first pressure roller 4 includes an outer roller body 12 and an inner roller body 11. The outer roller body 12 and the inner roller body 11 are coaxially arranged. A mounting hole is axially passed through the middle of the inner roller body 11. The cross-sectional shape of the mounting hole is the same as the cross-sectional shape of the first rotating shaft 6 or the second rotating shaft 7. The outer roller body 12 is sleeved on the outside of the inner roller body 11.

[0047] The inner roller body 11 cooperates with the first rotating shaft 6 or the second rotating shaft 7 through the mounting hole. The cross-sections of the mounting hole and the first rotating shaft 6 or the second rotating shaft 7 are both regular polygonal structures, so the inner roller body 11 maintains a synchronous rotation state with the first rotating shaft 6 or the second rotating shaft 7; the inner roller body 11 and the outer roller body 12 are sleeved, and the two can rotate synchronously under the action of friction, or the inner roller body 11 can rotate alone when the outer roller body 12 is obstructed.

[0048] In this embodiment, a flexible gasket 13 is connected to the bottom surface of the first pressing plate 1 , and the flexible gasket 13 protrudes from the bottom surface of the first pressing plate 1 .

[0049] The flexible gasket 13 can effectively increase the friction between the bottom surface of the first pressing plate 1 and the drawing paper, thereby improving the squeezing and fixing effect of the first pressing plate 1 on the drawing paper. That is, the flexible gasket 13 serves as a structural extension of the first pressing plate 1, and its bottom surface is located on the same plane as the bottom surfaces of the first pressing roller 4 and the second pressing roller 5;

[0050] The flexible gasket 13 can be made of flexible silicone, which has a fine texture and can reduce pressure damage to the drawing paper.

[0051] In this embodiment, a third mounting groove for mounting a flexible gasket 13 is formed on the bottom surface of the first pressing plate 1 .

[0052] The flexible gasket 13 is installed in a slotted manner, which can effectively improve the strength of the connection structure between the flexible gasket 13 and the first pressing plate 1 and improve the stability of the overall structure.

[0053] In this embodiment, a connecting plate 14 recessed into the rectangular frame is provided between opposite ends of the first straight plate 2 and the second straight plate 3 .

[0054] The opposite ends of the first straight plate 2 and the second straight plate 3 are formed into an inwardly concave shape through the connecting plate 14, and the inwardly concave space can be used as a accommodating space for the first knob 8 and the second knob 9. The first rotating shaft 6 and the second rotating shaft 7 respectively extend into the concave space and are connected to the first knob 8 and the second knob 9 respectively.

[0055] In this embodiment, a hand support plate 15 is further included. Both ends of the hand support plate 15 are provided with hook portions 16, and the hand support plate 15 is mounted on two opposite sides of the rectangular frame through the hook portions 16. The bottom surface height of the hand support plate 15 is higher than the bottom surface height of the first pressure plate 1.

[0056] The hand support plate 15 can be used as a place for the draftsman's hands. Since the bottom surface of the hand support plate 15 is higher than the bottom surface of the first pressing plate 1, it can support the draftsman's hands to prevent the draftsman's hands from contacting the drawing paper, thereby preventing the drawn pattern groove 10 from being damaged due to hand contact;

[0057] At the same time, the hand support plate 15 can also slide on the rectangular frame through the hook portion 16, so that the position of the hand support plate 15 can be adjusted according to the drawing position.

[0058] In this embodiment, a flexible cushion layer 17 is laid on the top surface of the hand support plate 15 .

[0059] The flexible cushion layer 17 may be a cloth pad, which can reduce the pressure on the draftsman's hands and has a breathable effect to improve comfort.

[0060] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model and are not limiting. Although the utility model is described in detail with reference to the preferred embodiments, ordinary technicians in this field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
