Technical Field

[0001] This utility model relates to the field of drawing rewinding, and in particular to a novel drawing rewinding device. Background Technology

[0002] An existing patent (publication number: CN220222827U) proposes a drawing rewinding device, belonging to the field of drawing rewinding technology. It includes a support base plate, a movable pressing device, a rewinding roller, a drawing fixing component, a limiting sleeve, a rotating shaft, a rotating motor, a controller, and a right mounting plate. The top of the support base plate has a groove, and the movable pressing device is installed through and mounted on one side of the support base plate. The movable pressing device is located inside the groove. However, this device can only rewind the drawing when in use and cannot unfold the drawing for display. Summary of the Invention

[0003] This utility model addresses the aforementioned shortcomings of the existing technology by providing a novel paper rolling device with a folding structure that can both roll up the paper and allow the paper to be unfolded and displayed by rotating the opening device.

[0004] The objective of this utility model is achieved through the following technical solution:

[0005] A novel drawing rewinding device includes a long folding plate, an end folding plate, a positioning shaft, a horizontal fixing plate, a positioning slide post, a telescopic sleeve, drawing side rods, drawing paper, a limiting slider, and a telescopic insertion rod. The long folding plate and the end folding plate are fitted together, and the long folding plate and the end folding plate are in opposite directions. The long folding plate is connected to the end folding plate through the positioning shaft. The side of the positioning shaft is connected to the horizontal fixing plate, which is fitted together with the long folding plate. The horizontal fixing plate has a strip-shaped sliding hole. The side of the telescopic sleeve is connected to the positioning slide post, which is adapted to the strip-shaped sliding hole. The positioning slide post is inserted into the strip-shaped sliding hole and slides within the strip-shaped sliding hole. The telescopic sleeve is connected to the drawing side rod, which has a rectangular magnetic block on its side. The rectangular magnetic block is connected to the telescopic sleeve. The drawing paper is symmetrically arranged on both sides of the telescopic sleeve.

[0006] The telescopic rod is adapted to the telescopic sleeve. The telescopic rod is inserted into the telescopic sleeve and slides inside the telescopic sleeve. The telescopic rod is symmetrically arranged at the upper and lower ends of the telescopic sleeve. The telescopic sleeve has a strip-shaped limiting hole. The telescopic rod is connected to a limiting slider. The limiting slider is adapted to the strip-shaped limiting hole. The limiting slider is inserted into the strip-shaped limiting hole and slides inside the strip-shaped limiting hole.

[0007] The telescopic rod is connected to a circular baffle on its side. The circular baffle has a side plate with an inner hole. The end folding plate is connected to a second connecting shaft. The second connecting shaft is adapted to the inner hole of the side plate. The second connecting shaft is inserted into the inner hole of the side plate and rotates within the inner hole of the side plate. Beneficial effects

[0008] 1. In this utility model, the long folding plate and the end folding plate are connected by a positioning shaft, allowing the long folding plate and the end folding plate to rotate around the positioning shaft. The strip-shaped limiting hole and the upper and lower symmetrical telescopic rods form a double-headed telescopic rod. The positioning sliding pin passes through the strip-shaped sliding hole and connects to the telescopic sleeve, so that the telescopic sleeve is installed on the side of the horizontal fixed plate and can slide horizontally along the horizontal fixed plate. The two ends of the drawing paper are installed on the telescopic sleeve by rectangular magnetic blocks, so that the drawing paper unfolds or folds with the movement of a set of telescopic sleeves. The horizontal fixed plate keeps the height of the telescopic sleeves consistent, preventing the vertical misalignment of a set of telescopic sleeves from causing wrinkles in the drawing paper when the drawing is rolled up, thus ensuring the flatness of the drawing paper.

[0009] 2. In this utility model, a limiting slider passes through a strip-shaped limiting hole to connect to a telescopic rod. The limiting slider prevents the telescopic rod from sliding out of the telescopic sleeve when the drawing is rolled up, ensuring the connection between the telescopic rod and the telescopic sleeve. A first connecting shaft passes through the inner hole of the side plate to connect to a long folding rotating plate, and a second connecting shaft passes through the inner hole of the side plate to connect to an end folding rotating plate. This allows the upper and lower ends of the telescopic rod to be connected to the shafts of the long folding rotating plate and the end folding rotating plate, respectively. The connection between the long folding rotating plate and the end folding rotating plate and the telescopic rod allows the components to interact with each other, keeping a set of telescopic sleeves parallel. The long folding rotating plate and the end folding rotating plate rotate simultaneously to form a foldable structure. When in use, the drawing paper can be unfolded and rolled up by rotating the long folding rotating plate and the end folding rotating plate. When the device is folded, the symmetrical drawing side rods roll up the drawing paper. After rolling, the rectangular magnetic block adheres to the telescopic sleeve to store the drawing paper.

The positioning slide post 06 is connected to the side of the telescopic sleeve 07, and the positioning slide post 06 is adapted to the strip-shaped sliding hole 05 and inserted into the strip-shaped hole 05. The sliding hole 05 and the positioning sliding post 06 slide within the strip-shaped sliding hole 05. The positioning sliding post 06 passes through the strip-shaped sliding hole 05 and connects to the telescopic sleeve 07, so that the telescopic sleeve 07 is installed on the side of the horizontal fixed plate 04 and can slide horizontally along the horizontal fixed plate 04. The horizontal fixed plate 04 keeps the height of the telescopic sleeve 07 consistent, preventing the vertical misalignment of a set of telescopic sleeves 07 from causing wrinkles in the drawing paper 09 when the drawing is rolled up, thus ensuring the flatness of the drawing paper 09. The telescopic sleeve 07 is connected to the drawing side rod 08. The drawing side rod 08 has a rectangular magnetic block 18 on its side, which is connected to the telescopic sleeve 07. The drawing paper 09 is symmetrically arranged on both sides of the telescopic sleeve 07. The two ends of the drawing paper 09 are installed on the telescopic sleeve 07 through the rectangular magnetic blocks 18, so that the drawing paper 09 unfolds or folds with the movement between a set of telescopic sleeves 07.

[0018] Example 2:

[0019] The telescopic rod 12 described in this utility model is adapted to the telescopic sleeve 07. The telescopic rod 12 is inserted into the telescopic sleeve 07 and slides within the telescopic sleeve 07. The telescopic rod 12 is symmetrically arranged at both the upper and lower ends of the telescopic sleeve 07. The strip-shaped limiting hole 11 and the symmetrically arranged telescopic rod 12 form a double-headed telescopic rod. The telescopic sleeve 07 has a strip-shaped limiting hole 11. The telescopic rod 12 is connected to a limiting slider 10. The limiting slider 10 is adapted to the strip-shaped limiting hole 11 and is inserted into the strip-shaped limiting hole 11. The limiting slider 10 slides within the strip-shaped limiting hole 11. When the drawing is rolled up, the limiting slider 10 prevents the telescopic rod 12 from sliding out of the telescopic sleeve 07, ensuring the connection between the telescopic rod 12 and the telescopic sleeve 07.
