Description

Technical Field

[0001] This utility model relates to the field of painting accessories, and more specifically, it relates to a paper holder. Background Technology

[0002] Paintings are very common in people's lives. By recording the scenes before their eyes through painting, people's spiritual lives can be greatly enriched. In the process of creating or displaying paintings, it is often necessary to fix the paper to make it flat for display and painting. Therefore, a paper holder is needed to fix the paper. Existing paper holders generally consist of a frame and a flat plate. The flat plate is set on the frame, and the paper is clamped to the flat plate with spring clips to fix it, or it is pasted to the flat plate with tape. When the area of ​​the paper is larger than the area of ​​the flat plate, the edge of the paper needs to be bent, and then the paper and the flat plate are clamped by spring clips to fix the paper to the flat plate. When the area of ​​the paper is smaller than the area of ​​the flat plate, spring clips cannot be used, and tape must be used. Using tape will damage the edge of the paper, making it inconvenient to use the holder and not convenient to fix the paper according to the needs of different papers. At the same time, the existing frame structure is a fixed frame structure, which makes it inconvenient to change the height, angle, etc. of the flat plate according to the needs of painting or display, thus affecting the creation and display of paintings.

After the height adjustment is completed, the bolt is inserted into the positioning hole to fix the position of the support rod, thus completing the height adjustment of the plate and facilitating the use of the entire fixing frame.

[0019] 3. This utility model, by setting a rotating connection between the rotating disk and the support rod, allows the plate and rotating disk to rotate when the angle of the plate is changed through the rotational cooperation of the second rotating column and the second rotating hole, thereby changing the tilt angle of the plate. The position of the plate is fixed by the damping between the second rotating column and the second rotating hole. When the drawing paper is rotated, the plate is driven to rotate through the cooperation of the first rotating column and the first rotating hole, thereby rotating the drawing paper and the plate to facilitate drawing. After the plate has rotated, the locking block set at the upper end of the rotating disk is rotated to screw the locking block into the limiting hole, thereby fixing the position of the plate and completing the rotation of the plate.

[0030] The fixed structure includes a movable frame 7, a pressure plate 8, and a spring 9. Multiple sets of fixed structures are provided. An elastic sheet 10 is fixedly provided at the rear end of the plate 5. Multiple elastic sheets 10 are provided. A notch 11 is provided on the plate 5. The notch 11 and the rotating disk 4 cooperate with each other and are rotatably connected.

[0031] In this embodiment, the main structure of the entire fixing frame is composed of the base 1, sleeve 2, support rod 3, rotating disk 4 and plate 5, which facilitates the adjustment of the fixing frame.

[0032] More specifically, the drawing paper is fixed to the flat plate 5 by a fixing structure, which makes it easier to fix the drawing paper.

[0033] Please see Figures 1-5 As one method for fixing the drawing paper: the movable frame 7 is provided with a first threaded rod 12 and a first sliding rod 13, and multiple first sliding rods 13 are provided. The extension block 6 is provided with a first through hole 14 that mates with the first threaded rod 12 and the first sliding rod 13. Multiple springs 9 are provided. The pressure plate 8 is provided with a second threaded rod 15 and a second sliding rod 16. The first threaded rod 12 is rotatably connected to the movable frame 7 via a bearing. Both the first threaded rod 12 and the first sliding rod 13 pass through the first through hole 14. The first threaded rod 12 is threadedly connected to the first through hole 14. The first sliding rod 13 is threadedly connected to the first through hole 14. The holes 14 are slidably connected. The movable frame 7 is provided with a second through hole 17 that cooperates with the second threaded rod 15 and the second slide rod 16. The second threaded rod 15 and the second slide rod 16 both pass through the second through hole 17. The spring 9 is disposed between the pressure plate 8 and the movable frame 7. The spring 9 is sleeved and installed on the second slide rod 16. The second threaded rod 15 is rotatably connected to the pressure plate 8 through a bearing. The second threaded rod 15 is threadedly connected to the movable frame 7. The second slide rod 16 is slidably connected to the movable frame 7. Both ends of the second slide rod 16 are provided with threads. One end of the second threaded rod 15 is threadedly connected to the pressure plate 8.

[0034] Specifically, when fixing drawing paper of different sizes, the two first threaded rods 12 are rotated respectively. Through the threaded connection between the first threaded rods 12 and the extension block 6, the rotation of the first threaded rods 12 causes the two movable frames 7 to move closer or further apart. Thus, according to the width of the drawing paper, the two movable frames 7 are moved to the edge of the drawing paper. The second threaded rod 15 at the upper end of the pressure plate 8 is rotated. Through the threaded connection between the second threaded rod 15 and the movable frame 7, the pressure plate 8 is driven to descend, thereby pressing the edge of the drawing paper tightly by the pressure plate 8, thus completing the fixing of the drawing paper.

[0035] Please refer to Figure 1-5 As one method of adjusting the entire fixed frame: a first rotating column 18 is provided on the rotating disk 4, a first rotating hole 19 is provided on the plate 5, the first rotating column 18 and the first rotating hole 19 are rotatably connected by a bearing, a limit hole 20 is provided on the plate 5, and multiple limit holes 20 are provided, a locking block 21 is provided on the rotating disk 4, and threads are provided on both the limit hole 20 and the locking block 21, a connecting block 22 is fixedly provided at the lower end of the rotating disk 4, a second rotating column 23 is provided at both ends of the connecting block 22, a second rotating hole 24 is provided at the upper end of the support rod 3, the second rotating column 23 is rotatably connected to the second rotating hole 24, a positioning hole 25 is provided on both the support rod 3 and the sleeve 2, multiple positioning holes 25 are provided on the support rod 3, threads are provided in the positioning holes 25, and bolts are used to connect the positioning holes 25 on the support rod 3 and the positioning holes 25 on the sleeve 2;

[0036] Specifically, when changing the height of the plate 5, the support rod 3 is pulled out of the sleeve 2, and the extension length of the support rod 3 is adjusted by matching the different positioning holes 25 on the support rod 3 with the positioning holes 25 on the sleeve 2, so that the plate 5 reaches the required height. After the height adjustment is completed, the bolt is inserted into the positioning hole 25 to fix the position of the support rod 3, thus completing the height adjustment of the plate 5. When changing the angle of the plate 5, the plate 5 and the rotating disk 4 are rotated by the rotational cooperation of the second rotating column 23 and the second rotating hole 24, thus changing the tilt angle of the plate 5. The position of the plate 5 is fixed by the damping between the second rotating column 23 and the second rotating hole 24. When rotating the drawing paper, the plate 5 is rotated by the cooperation of the first rotating column 18 and the first rotating hole 19, thereby rotating the drawing paper and the plate 5 to facilitate drawing. After the plate 5 has rotated, the locking block 21 set at the upper end of the rotating disk 4 is rotated and screwed into the limiting hole 20 to fix the position of the plate 5, thus completing the rotation of the plate 5.

[0037] In summary, when using it as a whole:

[0038] When fixing drawing paper of different sizes, the two first threaded rods 12 are rotated respectively. Through the threaded connection between the first threaded rods 12 and the extension block 6, the rotation of the first threaded rods 12 causes the two moving frames 7 to move closer or further apart. Thus, according to the width of the drawing paper, the two moving frames 7 are moved to the edge of the drawing paper. The second threaded rod 15 at the upper end of the pressure plate 8 is rotated. Through the threaded connection between the second threaded rod 15 and the moving frame 7, the pressure plate 8 is driven to descend, thereby pressing the edge of the drawing paper tightly by the pressure plate 8, thus completing the fixing of the drawing paper.

[0039] When the angle of the plate 5 is changed, the plate 5 and the rotating disk 4 are rotated through the rotational cooperation of the second rotating column 23 and the second rotating hole 24, changing the tilt angle of the plate 5. The position of the plate 5 is fixed by the damping between the second rotating column 23 and the second rotating hole 24. When the drawing paper is rotated, the plate 5 is driven to rotate through the cooperation of the first rotating column 18 and the first rotating hole 19, thereby rotating the drawing paper and the plate 5, which facilitates drawing. After the plate 5 has rotated, the locking block 21 set at the upper end of the rotating disk 4 is rotated and screwed into the limiting hole 20 to fix the position of the plate 5, thus completing the rotation of the plate 5.

[0040] When changing the height of the plate 5, the support rod 3 is pulled out of the sleeve 2, and the extension length of the support rod 3 is adjusted by matching the different positioning holes 25 on the support rod 3 with the positioning holes 25 opened on the sleeve 2, so that the plate 5 reaches the required height. After the height adjustment is completed, the bolt is inserted into the positioning hole 25 to fix the position of the support rod 3, thus completing the height adjustment of the plate 5.

[0041] Of all the solutions mentioned above, those involving the connection between two components can be selected according to the actual situation, such as welding, bolt and nut connection, bolt or screw connection, or other known connection methods, which will not be elaborated here. For all the fixed connections mentioned above, welding is preferred. Although embodiments of this utility model have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of this utility model. The scope of this utility model is defined by the appended claims and their equivalents.
