Description

Technical Field

[0001] This utility model relates to the field of painting tools technology, and in particular to a folding easel with a rotatable drawing board. Background Technology

[0002] When painting outdoors, artists need to carry easels and canvases. Traditional Chinese paintings use a lot of ink, and absorbent cloths or paper are placed underneath the paper to absorb the ink. For ease of transport, folding easels are commonly used. However, existing folding easels suffer from problems such as an unreasonable folding structure, bulky canvases that are inconvenient to carry, the inability to rotate the canvas when unfolded, and the inability to change the canvas's orientation, causing inconvenience to users. For example, patent CN220374178U provides an adjustable folding easel, but the canvas can only be supported vertically and cannot rotate. Patent CN217013141U provides a portable carrying case-style folding easel, but the canvas can only be folded and cannot rotate, making it inconvenient to use. Therefore, a new folding easel is needed to solve these problems. Summary of the Invention

[0003] The technical problem solved by this utility model is to provide a folding easel with a rotatable canvas. This easel has the advantages of the canvas being able to rotate to change direction, the ability to quickly switch between horizontal and vertical formats, simple folding, and easy portability.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A folding easel with a rotatable drawing board, characterized in that it includes a frame, a folding cover plate mounted on the upper surface of the frame, a rotating support frame mounted on the folding cover plate, and a rollable magnetic felt board; the folding cover plate includes a front support plate and a rear support frame, the rear support frame including a central horizontal bar and two side uprights at both ends, the rear ends of the side uprights having multiple support ends; the front side of the front support plate is hinged to the upper front side of the frame using a pin, and the rear side is hinged to the horizontal bar of the rear support frame; multiple support holes are provided on the end faces of both sides of the frame; the rear end of the front support plate tilts upward and flips, and the rear ends of the two side uprights of the rear support frame tilt downward and to the side, providing support. The end is inserted into the support hole, so that the front support plate and the rear support frame form an inverted V-shaped support frame on the upper part of the box frame; the rotating support frame includes a rotating plate and two folding steel frames. The middle part of the rotating plate is connected to the front support plate through a rotating support shaft. The rotating plate can rotate around the rotating support shaft on the front support plate; the two ends of the rotating plate are provided with steel frame slots. The folding steel frames are installed on the rotating plate using the steel frame slots; the folding steel frames unfold to both sides and are parallel to the rotating plate to form an unfolded rotating support frame. The curled magnetic felt plate is unfolded and fixed on the rotating support frame. The folding steel frames can be stacked together with the rotating plate after being folded inward; the bottom of the box frame is provided with folding support legs.

[0006] Furthermore, the interior of the box frame is divided into upper and lower layers by a partition. The folding support legs can be folded and placed at the bottom of the box frame, while the upper layer of the box frame serves as a storage space. The box frame is equipped with handles on the side.

[0007] Furthermore, the inner side of the steel frame slot of the rotating plate is provided with an anti-falling plate, and the two ends of the folding steel frame are provided with fixing columns.

[0008] Furthermore, the rollable magnetic felt board includes a roller shutter layer, an iron sheet layer, and a felt cloth layer. The roller shutter layer is woven from long rods and ropes. The long rods can be bamboo, wood, plastic, or metal. The iron sheet layer is a single flexible rollable iron sheet or a strip of iron sheet attached to the long rod of the roller shutter layer. The rollable magnetic felt board has metal clamps at both ends that connect to the folding steel frame. The metal clamps have hanging holes that connect to the fixing posts of the folding steel frame.

[0009] This utility model has the following beneficial effects:

[0010] This invention utilizes a front support plate and a rear support frame to form an inverted V-shaped support frame on the upper part of the box frame. The folding structure is reasonable, allowing for quick unfolding and stable support after unfolding, making operation simple and fast. The rotating support frame is connected to the front support plate via a rotating support shaft. The rotating plate can rotate around the rotating support shaft on the front support plate, thereby driving the rotating support frame and the rollable magnetic felt board to rotate, allowing for quick switching between horizontal and vertical canvases. The rollable magnetic felt board, after unfolding, is fixed to the rotating support frame. The rotating support frame supports the long rod of the roller blind layer, allowing the rollable magnetic felt board to form a flat canvas. The iron sheet layer can attract magnets to secure the drawing paper, and the felt cloth layer can absorb excess ink during painting. When not in use, the rollable magnetic felt board can be quickly rolled up for storage, reducing the size and weight of the canvas and making it easy to carry. Attached Figure Description

The support plate is tilted downwards, with the support end 4-1 inserted into the support hole, forming an inverted V-shaped support frame on the upper part of the box frame with the front support plate and the rear support frame. The rotating support frame includes a rotating plate 7 and two folding steel frames 8. The middle part of the rotating plate is connected to the front support plate through a rotating support shaft 9, and the rotating plate can rotate around the rotating support shaft on the front support plate. The rotating plate has steel frame slots 10 at both ends, and the folding steel frames 8 are installed on the rotating plate 7 using the steel frame slots 10. The folding steel frames 8 unfold to both sides and are parallel to the rotating plate to form an unfolded rotating support frame. The curled magnetic felt plate 2 is unfolded and fixed on the rotating support frame. The folding steel frames 8 can be stacked together with the rotating plate 7 after being folded inwards. The rotating plate 7 has an anti-falling bracket 6 on the inner side of the steel frame slot 10. The folding steel frames have fixing posts 14 at both ends. After the folding steel frame 8 is unfolded to both sides, the anti-falling bracket 6 limits the folding steel frame 8 to prevent it from falling off. When the folding steel frame 8 is folded inward, the anti-falling bracket no longer limits the folding steel frame 8, and the folding steel frame 8 can be removed from the rotating plate after retracting inward. The bottom of the box frame 1 is provided with folding support legs 11. The interior of the box frame 1 is divided into upper and lower layers by a partition 12. The folding support legs can be folded and placed in the bottom layer of the box frame, and the upper layer of the box frame serves as storage space. The side of the box frame is provided with a handle 13. The rollable magnetic felt board includes a roller shutter layer 2-1, an iron sheet layer 2-2, and a felt cloth layer 2-3. The roller shutter layer is woven from long rods and ropes. The long rods can be bamboo, wood, plastic, or metal.
