Description

Technical Field

[0001] This utility model relates to the field of art paper winding technology, specifically to a convenient art paper winding device. Background Technology

[0002] Fine arts refers to art forms that occupy a certain two-dimensional space and are visually appealing. It generally includes painting, sculpture, design, and architecture. Some modern scholars also include calligraphy and photography within fine arts. Painting is a type of fine arts that cultivates aesthetic appreciation and refines one's sentiments. Technically, painting involves using a surface as a support and then adding color on top of it. Art paper is an essential tool used in the painting process.

[0003] Currently, in practical use, art paper has a large flat area, so a winding device is needed to wind and store it. Some existing art paper winding devices do not have the function of adjusting the length, and different art papers have different widths. Therefore, art paper winding devices can only wind up art paper that is shorter than their own length, resulting in low applicability of art paper winding devices. Utility Model Content

[0004] The purpose of this invention is to provide a convenient art paper winding device to address the aforementioned shortcomings in the technology.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a convenient art paper winding device, comprising:

An annular groove is provided at the end of the take-up rod near the rotating ring. The two annular sliders are respectively located inside the two annular grooves.

[0007] Two adjusting rods are respectively located inside two winding rods. A bidirectional threaded rod is fixedly provided in the middle of the rotating ring. Each of the two adjusting rods has a threaded groove at one end near the bidirectional threaded rod. Both ends of the bidirectional threaded rod extend into the two threaded grooves and are connected to the threaded grooves by threads.

[0008] Preferably, two limiting sliders are integrally connected to the outer side of the end of the adjusting rod near the rotating ring, and two limiting grooves are opened on the inner wall of the winding rod. The two limiting sliders are respectively located inside the two limiting grooves to facilitate the limiting and guiding of the adjusting rod.

[0009] Preferably, the cross-sections of the annular slider and the annular groove are T-shaped.

[0010] Preferably, the end of the adjusting rod away from the rotating ring is provided with an end limiting block, and an annular limiting groove is provided on the inner side of the end limiting block to facilitate limiting the end of the rolled-up art paper.

[0011] Preferably, the inner diameter of the annular limiting groove is the same as the outer diameter of the winding rod, which facilitates the entry of the end of the wound art paper into the annular limiting groove.

[0012] Preferably, a fixing rod is fixedly provided at the end of the adjusting rod away from the rotating ring, one end of the fixing rod passes through the middle of the end limiting block, and a connecting plate is fixedly provided at one end of the fixing rod to facilitate the position adjustment of the end limiting block.

[0025] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0026] This utility model provides, for example Figures 1 to 6 A convenient art paper winding device is shown, comprising:

[0027] Two take-up rods 1 are provided, and a rotating ring 2 is provided between the two take-up rods 1. An annular slider 6 is fixed at both ends of the rotating ring 2. An annular groove 7 is provided at one end of the take-up rod 1 near the rotating ring 2. The two annular sliders 6 are respectively provided inside the two annular grooves 7. The cross-section of the annular sliders 6 and the annular grooves 7 is T-shaped.

[0028] Two adjusting rods 3 are respectively located inside the two winding rods 1. A bidirectional threaded rod 4 is fixedly provided in the middle of the rotating ring 2. Each of the two adjusting rods 3 has a threaded groove 5 at one end near the bidirectional threaded rod 4. Both ends of the bidirectional threaded rod 4 extend into the two threaded grooves 5 and are connected to the threaded grooves 5 by threads. Two limiting sliders 8 are integrally connected to the outside of the adjusting rod 3 near the rotating ring 2. Two limiting grooves 9 are provided on the inner wall of the winding rod 1. The two limiting sliders 8 are respectively located inside the two limiting grooves 9.

[0029] An end limit block 10 is provided at the end of the adjusting rod 3 away from the rotating ring 2. An annular limit groove 11 is provided on the inner side of the end limit block 10. The inner diameter of the annular limit groove 11 is the same as the outer diameter of the winding rod 1. A fixing rod 12 is fixedly provided at the end of the adjusting rod 3 away from the rotating ring 2. One end of the fixing rod 12 passes through the middle of the end limit block 10. A connecting plate 13 is fixedly provided at one end of the fixing rod 12. A spring 14 is sleeved on the outer end of the fixing rod 12. The two ends of the spring 14 are fixedly connected to the inner side of the connecting plate 13 and the outer side of the end limit block 10, respectively.

[0030] Hold the two take-up rods 1 by hand and rotate the rotating ring 2. The rotating ring 2 drives the double-threaded rod 4 to rotate. Since the double-threaded rod 4 and the threaded groove 5 are connected by threads, the two adjusting rods 3 extend to both sides as the double-threaded rod 4 rotates. This allows you to adjust the total length of the two take-up rods 1 and the adjusting rods 3. When the total length of the two take-up rods 1 and the adjusting rods 3 is suitable for the width of the art paper, stop rotating the rotating ring 2.

[0031] Pull the two end limiting blocks 10 to both sides. The two end limiting blocks 10 will move outward along the fixed rod 12 and compress the spring 14. At this time, attach one end of the art paper to the outer end of the two winding rods 1, so that the two ends of the art paper along the width are located inside the two end limiting blocks 10 respectively. After the art paper is wound up to the outer end of the winding rod 1 and the adjusting rod 3, release the end limiting blocks 10. The end limiting blocks 10 move towards the end of the art paper under the elastic force of the spring 14. At this time, the end of the art paper after being wound up will enter the interior of the annular limiting groove 11. In this way, the two annular limiting grooves 11 will limit the two ends of the art paper after being wound up.

[0032] This invention adjusts the position of the two adjusting rods 3 inside the winding rod 1 by rotating the rotating ring 2, thereby adjusting the total length of the two winding rods 1 and the two adjusting rods 3. This makes it suitable for winding and organizing art paper of different widths, resulting in high applicability. The end limiting blocks 10 and the annular limiting grooves 11 at both ends can limit the ends of the wound art paper, effectively improving the winding and organizing efficiency. This embodiment specifically solves the problem in the prior art where, due to the large flat area of ​​art paper, a winding device is needed to wind and store it. Some existing art paper winding devices do not have the function of adjusting the length, and since different art papers have different widths, the art paper winding device can only wind art paper shorter than its own length, resulting in low applicability of the art paper winding device.

[0033] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
