Technical Field

[0001] The invention relates to the technical field of art easels, in particular to an art easel that can be used by multiple people at the same time. Background Art

[0002] In the process of art students' learning, in order to exercise and improve their observation, expression and creativity, and better understand and express the artistic elements of nature and life, the school usually leads students to sketch outdoors. Since the number of students led by the school is generally large, each student usually brings an art easel to the sketching site. Since art sketching usually goes to relatively far places, such as scenic spots, it takes several consecutive days;

[0003] Art easels are usually made of wood or metal, which is relatively heavy. Each person needs to bear the weight of the easel in addition to the weight of their own belongings, which increases the complexity of going to the sketching site. It is not only inconvenient to carry, but also the space at the sketching site is limited. Each student will take up a certain amount of space if they bring an easel, which limits the space at the sketching site, causing crowding, obstruction of other art students' vision, and insufficient space in the transportation vehicle they take.

[0004] At the same time, in order to reduce the number of painting tools and equipment required, save costs and reduce waste of materials and the environment.

[0005] Based on this, the present invention designs an art easel that can be used by multiple people at the same time to solve the above problems. Summary of the invention

[0024] 3. By placing the device vertically on the ground and twisting the rotating block, the rotating block drives the spiral rod to rotate, and the thread on the spiral rod drives the first spiral sleeve to move downward. After the first spiral sleeve moves downward, it drives the fixed frame to gradually change from an inclined state to a horizontal state, and pushes the three brackets apart from a closed state to form a triangle, which can be used to stabilize the device. The stability principle of the triangle is utilized, and a stable effect can be achieved by using less structure. BRIEF DESCRIPTION OF THE DRAWINGS

[0035] During operation: the device is placed vertically on the ground, and the rotating block 3 is twisted. The rotating block 3 drives the spiral rod 1 to rotate, and the thread on the spiral rod 1 drives the first spiral sleeve 7 to move downward. After the first spiral sleeve 7 moves downward, the first spiral sleeve 7 drives the fixed frame 8 to gradually change from an inclined state to a horizontal state, and the three brackets 5 are pushed outward from a closed state to form a triangle, which can be used to stabilize the device. The stability principle of the triangle is utilized, and a stable effect can be achieved by utilizing less structure.

[0036] As a further solution of the present invention, the multi-person easel assembly includes a second spiral sleeve 11, the second spiral sleeve 11 is threadedly connected to the spiral rod 11, and the thread in the second spiral sleeve 11 is opposite to the thread in the first spiral sleeve 7;

[0037] Three first connecting frames 13 are distributed in a circumferential array on the second threaded sleeve 11, each of the first connecting frames 13 is hinged to the outer side of the second threaded sleeve 11, and the middle of the first connecting frame 13 is rotatably connected to the second connecting frame 12;

[0038] The first connecting frame 13 is rotatably connected to one end away from the second threaded sleeve 11 with a first slider 17, and both sides of the slider 17 are fixedly connected to first sliding rods 18, and each of the first sliding rods 18 is fixedly connected to a fixed plate 14, and the lower end of each of the fixed plates (14) is slidably connected to a second sliding rod 23, and the second sliding rods 23 are commonly connected to a second slider 22, and the second slider 22 is hinged to the lower end of the second connecting frame 12, and the upper end of the second connecting frame 12 is hinged to a limiting cylinder 10, and the limiting cylinder 10 is fixedly connected to the lower end of the fixed block 2;

[0041] The lower end of the first connecting rod 15 and the upper end of the second hinge rod 16 are rotatably connected to the fixing plate 14 .

[0042] During operation: while the spiral rod 1 rotates, since the threads of the first spiral sleeve 7 and the second spiral sleeve 11 are opposite, the second spiral sleeve 11 moves upward. When the second spiral sleeve 11 moves upward, the second spiral sleeve 11 can push the fixing plate 14 outward through the first connecting frame 13 and the second connecting frame 12 to unfold. When the first connecting frame 13 and the second connecting frame 12 push the fixing plate 14 outward, the ends of the first connecting frame 13 and the second connecting frame 12 slide on the fixing plate 14 through the first sliding block 17, and the angle between the first connecting frame 13 and the second connecting frame 12 becomes smaller, thereby driving The angle between the first hinge rod 15 and the second hinge rod 16 becomes smaller, and the two first hinge rods 15 and the second hinge rods 16 are close to each other to push the fixed plate 14 outward along the first sliding rod 18 to expand, thereby increasing the area of ​​the fixed plate 14, so that the art students can place the drawing board more stably, and then the user can sit in front of the corresponding fixed plate 14, and the bottom of the drawing board is placed on the limiting groove 19. Since the fixed plates 14 are located on three sides, three students can use it at the same time.

At the same time, three users share one easel, which can promote communication and cooperation among students, enable them to observe and learn from each other, jointly solve problems in the painting process, and promote each other's artistic growth and improvement of skills.

[0045] As a further solution of the present invention, the lower end of the first spiral rod 7 is fixedly connected with a rotating block 6. During operation, if different angles of fixation are required, the rotating block 6 can be manually rotated to change the opening and closing angles of the three brackets 5.

[0046] As a further solution of the present invention, a placement groove is provided on the rotating block 3, which can be used to place a painting brush during operation.

[0047] As a further solution of the present invention, the lower end of the spiral rod 1 can be set to be conical, which facilitates the spiral rod 1 to rotate and be fixed to the ground during operation.

[0050] Working principle: Place the device vertically on the ground and twist the rotating block 3. The rotating block 3 drives the spiral rod 1 to rotate. The thread on the spiral rod 1 drives the first spiral sleeve 7 to move downward. After the first spiral sleeve 7 moves downward, the first spiral sleeve 7 drives the fixed frame 8 to gradually change from an inclined state to a horizontal state. The three brackets 5 are pushed outward from a closed state to form a triangle, which can be used to stabilize the device. The stability principle of the triangle is utilized and a stable effect can be achieved with less structure.

[0051] When the spiral rod 1 rotates, since the threads of the first spiral sleeve 7 and the second spiral sleeve 11 are opposite, the second spiral sleeve 11 moves upward. When the second spiral sleeve 11 moves upward, the second spiral sleeve 11 can push the fixing plate 14 outward through the first connecting frame 13 and the second connecting frame 12 to expand. When the first connecting frame 13 and the second connecting frame 12 push the fixing plate 14 outward, the ends of the first connecting frame 13 and the second connecting frame 12 slide on the fixing plate 14 through the first sliding block 17, and the angle between the first connecting frame 13 and the second connecting frame 12 becomes smaller, thereby driving the first connecting frame 13 and the second connecting frame 12 to move upward. The angle between the hinge rod 15 and the second hinge rod 16 becomes smaller, and the two first hinge rods 15 and the second hinge rods 16 are moved closer to each other to push the fixed plate 14 outward along the first sliding rod 18 to expand, thereby increasing the area of ​​the fixed plate 14, so that the art students can place the drawing board more stably. Then the user can sit in front of the corresponding fixed plate 14, and the bottom of the drawing board is placed on the limiting groove 19. Since the fixed plates 14 are located on three sides, three students can use it at the same time. Since art students need to sketch and paint everywhere, the device occupies a small space, has a simple structure, a low cost, and is easy to carry.

[0052] The problem that the art easel is relatively heavy and bulky and each person needs to bear the weight of the art easel in addition to the weight of his or her own belongings, which increases the complexity of going to the sketching location.

[0053] It also saves costs and reduces waste of materials and the environment. At the same time, three users share one easel, which can promote communication and cooperation among students, enable them to observe and learn from each other, jointly solve problems in the painting process, and promote each other's artistic growth and improvement of skills.

[0054] The lower end of the first spiral rod 7 is fixedly connected with a rotating block 6. During operation, if different angles of fixation are required, the rotating block 6 can be manually rotated to change the opening and closing angles of the three brackets 5.
