Description

Technical Field

[0001] The present application relates to the technical field of art easels, and in particular to a multifunctional easel device capable of adjusting painting angles and lighting. Background Art

[0002] The art drawing easel device is an indispensable tool in artistic creation, which is mainly composed of a fixed bracket and a drawing board tiltedly placed on the fixed bracket.

[0003] Most existing easel devices are usually designed with a fixed drawing board angle, which means that users cannot adjust the drawing board's tilt angle according to their personal painting habits, work requirements or physical comfort. This fixedness greatly limits the practicality and adaptability of the easel, making it difficult for users of different heights, sitting postures or painting styles to obtain the best painting experience.

[0004] In order to solve this problem, some easel devices that can adjust the angle of the drawing board have appeared on the market. These new easels have achieved flexible adjustment of the angle of the drawing board by introducing complex adjustment structures. However, these adjustment structures are often designed too complicated, which not only increases the manufacturing cost, but also makes the operation cumbersome and unintuitive. Users may need to spend extra time and energy to familiarize themselves with and master the adjustment method when using it, thereby reducing the efficiency and fun of painting.

[0005] Therefore, the present application provides a multifunctional easel device capable of adjusting drawing angle and lighting to solve the above problems. Summary of the invention

[0006] The present application provides a multifunctional easel device capable of adjusting drawing angle and lighting, aiming to solve the problems in the prior art that the angle adjustment structure of the drawing board of the existing easel device is too complicated and cumbersome, and the user needs to adjust the angle of the drawing board back and forth to adapt to his or her best angle during the adjustment process.

[0007] To achieve the above-mentioned purpose, the present application provides the following technical solutions: a multifunctional easel device capable of adjusting painting angle and lighting, comprising a support leg, a support rod arranged on the support leg, a drawing board arranged on one end of the support rod away from the support leg, and an adjustment structure 1 arranged on the support rod for adjusting the circular angle of the drawing board in a side-view plane;

[0008] In order to facilitate lighting the drawing board: it also includes a lighting structure arranged on the drawing board; the addition of the lighting structure enables the user to clearly see the content on the drawing board in a dimly lit environment, which greatly improves the efficiency and quality of painting.

[0009] In order to facilitate the circular angle adjustment of the drawing board in the side plane: the adjustment structure 1 includes a sphere fixedly connected to one end of the support rod away from the support leg, a ball sleeve rotatably mounted on the sphere and connected to the drawing board, a driving screw rotatably inserted in the support rod, a threaded sleeve plate mounted on the driving screw and extending to the outside of the support rod, a hinged plate hinged between the threaded sleeve plate and the ball sleeve, and a driving member for driving the driving screw to rotate. When adjusting the angle of the drawing board, the driving screw is first driven to rotate by the driving member. Since the threaded sleeve plate is mounted on the driving screw, when the driving screw rotates, the threaded sleeve plate will move up and down along the driving screw. During the movement of the threaded sleeve plate, the ball sleeve is driven to rotate on the sphere through the hinged plate. Since the ball sleeve is connected to the drawing board, the rotation of the ball sleeve will be transmitted to the drawing board, thereby changing the tilt angle of the drawing board. In this way, the tilt angle of the drawing board can be conveniently adjusted to meet the needs of different users.

[0010] Preferably, in order to facilitate the guiding of the threaded sleeve during the up and down movement and prevent the threaded sleeve from rotating in the circumferential direction, a vertical groove is provided on the support rod for the threaded sleeve to be lifted and lowered. The design of the vertical groove enables the threaded sleeve to maintain a stable motion trajectory during the lifting process, avoiding adjustment errors caused by shaking or rotation, thereby improving the accuracy of the drawing board angle adjustment.

[0011] Preferably, in order to reduce the wear between the driving screw and the support rod: bearings are provided between the two ends of the driving screw and the support rod. The addition of bearings effectively reduces the friction and wear between the driving screw and the support rod.

Through the mutual cooperation of the sliding rod, the U-shaped rod and the spring, the clamping structure can ensure that the drawing paper remains flat and stable during the painting process, avoiding the problem of affecting the painting effect due to shaking or displacement.

[0016] Preferably, in order to reduce the wear of the drawing paper by the U-shaped rod: a roller is rotatably mounted on the U-shaped rod. The addition of the roller effectively reduces the direct contact area between the U-shaped rod and the drawing paper, thereby reducing the wear of the drawing paper. This is of great significance for protecting precious drawing paper and extending its service life.

[0031] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0032] This embodiment provides a multifunctional easel device capable of adjusting the painting angle and lighting. Figure 1-6 As shown, the easel device comprises a supporting leg 1, a supporting rod 2 arranged on the supporting leg 1, a drawing board 3 arranged on one end of the supporting rod 2 away from the supporting leg 1, and an adjusting structure 4 arranged on the supporting rod 2 for adjusting the circular angle of the drawing board 3 in a side plane;

[0033] In order to facilitate the circular angle adjustment of the drawing board 3 in the side plane: the adjustment structure 14 includes a sphere 41 fixedly connected to the end of the support rod 2 away from the support leg 1, a ball sleeve 42 rotatably mounted on the sphere 41 and connected to the drawing board 3, a driving screw 43 rotatably inserted in the support rod 2, a threaded sleeve 44 mounted on the driving screw 43 and extending to the outside of the support rod 2, a hinged plate 45 hinged between the threaded sleeve 44 and the ball sleeve 42, and a driving member 46 for driving the driving screw 43 to rotate. Through the design of the adjustment structure 14, the circular angle adjustment of the drawing board 3 in the side plane is realized, so that the inclination angle of the drawing board 3 can be more in line with the needs of the user, and it is convenient for different groups. The easel device of the present application has a simple structure, is easy to operate, and is easy to promote and use. When adjusting the angle of the drawing board 3, the driving screw 43 is first driven to rotate by the driving member 46. Since the threaded sleeve 44 is sleeved on the driving screw 43, when the driving screw 43 rotates, the threaded sleeve 44 will move up and down along the driving screw 43. During the movement of the threaded sleeve 44, the ball sleeve 42 is driven to rotate on the sphere 41 through the hinge plate 45. Since the ball sleeve 42 is connected to the drawing board 3, the rotation of the ball sleeve 42 will be transmitted to the drawing board 3, thereby changing the inclination angle of the drawing board 3. When the driving screw 43 rotates clockwise, the threaded sleeve 44 rises, and the angle between the drawing board 3 and the support rod 2 is increased through the lever action of the hinge plate 45; conversely, when the driving screw 43 rotates counterclockwise, the threaded sleeve 44 descends, and the angle between the drawing board 3 and the support rod 2 is reduced. In this way, the inclination angle of the drawing board 3 can be easily adjusted to meet the needs of different users.

[0034] Specifically, in order to facilitate the guiding of the threaded sleeve 44 in the process of moving up and down, and to prevent the threaded sleeve 44 from rotating in the circumferential direction: a vertical slot 21 is provided on the support rod 2 for the lifting and lowering of the threaded sleeve 44. The design of the vertical slot 21 enables the threaded sleeve 44 to maintain a stable motion trajectory during the lifting process, avoiding the adjustment error caused by shaking or rotation, thereby improving the accuracy of the angle adjustment of the drawing board 3. The guiding and anti-rotation effect of the vertical slot 21 on the threaded sleeve 44 effectively enhances the stability of the adjustment structure, making it difficult for the drawing board 3 to shake or tilt during the adjustment process, thereby improving the stability of the entire easel device. Due to the guiding effect of the vertical slot 21, the user does not need to pay too much attention to the motion trajectory of the threaded sleeve 44 when adjusting the angle of the drawing board 3. The tilt angle adjustment of the drawing board 3 can be achieved by driving the driving screw 43 to rotate through the driving member 46, thereby simplifying the operation process and improving the use efficiency. When adjusting the angle of the drawing board 3, the user drives the driving screw 43 to rotate through the driving member 46. The threaded sleeve 44 is driven by the driving screw 43 to move up and down along the vertical groove 21. Due to the guiding and anti-rotation effect of the vertical groove 21 on the threaded sleeve 44, the threaded sleeve 44 can maintain stable and accurate movement up and down. At the same time, the threaded sleeve 44 drives the ball sleeve 42 to rotate on the ball 41 through the hinge plate 45, thereby changing the tilt angle of the drawing board 3.

[0035] Specifically, in order to reduce the wear between the driving screw 43 and the support rod 2: bearings 431 are provided between the two ends of the driving screw 43 and the support rod 2. The addition of the bearings 431 effectively reduces the friction and wear between the driving screw 43 and the support rod 2. This not only prolongs the service life of the driving screw 43 and the support rod 2, but also reduces the noise and vibration caused by wear, thereby improving the stability and reliability of the entire easel device.

[0036] Specifically, in order to facilitate the manual adjustment of the rotation of the driving screw 43: the driving member 46 includes a first bevel gear 461 rotatably arranged in the support rod 2 and fixedly connected to the shaft of the driving screw 43, a second bevel gear 462 rotatably arranged in the support rod 2 and meshingly connected to the first bevel gear 461, a driving rod 463 rotatably plugged into the support rod 2 and fixedly connected to the shaft of the second bevel gear 462, and a handwheel 464 fixedly connected to the end of the driving rod 463 away from the second bevel gear 462. Through the design of the handwheel 464, the user can intuitively adjust the inclination angle of the drawing board 3 by rotating the hand without the aid of other tools, and the operation is simple and quick. The driving member 46 adopts a bevel gear transmission inside, so that the entire adjustment mechanism has a compact structure, occupies a small space, and ensures the stability and reliability of the transmission. Due to the cooperation between the driving screw 43 and the threaded sleeve 44, and the precise control of the driving rod 463 by the handwheel 464, the inclination angle of the drawing board 3 can be adjusted in a wide range, which can meet the painting needs of different users. When adjusting the tilt angle of the drawing board 3, the user drives the driving rod 463 to rotate by rotating the hand wheel 464. The rotation of the driving rod 463 drives the second bevel gear 462 to rotate synchronously. Since the second bevel gear 462 is meshed and connected with the first bevel gear 461, the rotation of the second bevel gear 462 will be transmitted to the first bevel gear 461, but the rotation direction is opposite. The rotation of the first bevel gear 461 drives the driving screw 43 to rotate. When the hand wheel 464 drives the driving rod 463 and the second bevel gear 462 to rotate clockwise, the second bevel gear 462 drives the first bevel gear 461 to rotate counterclockwise, thereby causing the driving screw 43 to rotate counterclockwise. Since the threaded sleeve 44 and the driving screw 43 are threaded, the threaded sleeve 44 will descend along the support rod 2 under the rotation of the driving screw 43, thereby reducing the angle between the drawing board 3 and the support rod 2. On the contrary, when the hand wheel 464 drives the driving rod 463 and the second bevel gear 462 to rotate counterclockwise, the second bevel gear 462 drives the first bevel gear 461 to rotate clockwise, thereby rotating the driving screw 43 clockwise. At this time, the threaded sleeve 44 will rise along the support rod 2 under the rotation of the driving screw 43, thereby increasing the angle between the drawing board 3 and the support rod 2.

[0037] Specifically, in order to improve the support stability of the device: three support legs 1 are provided, and the three support legs 1 are fixedly connected in a circular array to the end of the support rod 2 away from the drawing board 3. The three support legs 1 are arranged in a circular array to form a stable triangular support structure, which greatly improves the support stability of the device. The stable support structure allows users to focus more on creation during the painting process without worrying about the stability and safety of the device. At the same time, the overall structure of the device is compact and reasonable, occupies a small area, is easy to carry and move, and provides users with a more convenient use experience.

[0038] In order to facilitate the lighting of the drawing board 3: it also includes a lighting structure 5 arranged on the drawing board 3; the lighting structure 5 includes a U-shaped card plate 51 clamped on the drawing board 3, a flexible lamp pole 52 fixedly connected to the end of the U-shaped card plate 51 away from the support rod 2, a lighting lamp 53 fixedly connected to the end of the flexible lamp pole 52 away from the U-shaped card plate 51, and a first screw 54 threadedly plugged into the U-shaped card plate 51 and in conflict with the drawing board 3. Among them, the flexible lamp pole 52 is made of highly elastic and corrosion-resistant alloy material, which can be freely bent and adjusted according to actual needs to ensure that the lighting lamp 53 can accurately illuminate every detail on the drawing board 3. The addition of the lighting structure 5 makes it unnecessary to equip additional lighting equipment when painting in an environment with insufficient light, reducing the cost of use and improving the painting experience. The addition of the lighting structure 5 enables users to clearly see the content on the drawing board 3 even in a dark environment, greatly improving the efficiency and quality of painting. Through the cooperation of the U-shaped card plate 51 and the first screw 54, the user can install the lighting structure 5 on any side position of the drawing board 3 according to actual needs, further improving the flexibility and effect of lighting. The lighting lamp 53 uses a high-brightness, low-energy LED light source, which not only provides sufficient lighting, but also reduces energy consumption and heat generation, which is in line with the energy-saving and environmental protection concept of modern society. In dim light conditions, align the card slot of the U-shaped card plate 51 with the edge of the drawing board 3 and gently snap it in. According to the thickness of the drawing board 3, rotate the first screw 54 so that it is in close contact with the drawing board 3 to achieve a stable installation of the lighting structure 5. According to actual needs, adjust the bending angle of the flexible lamp pole 52 so that the lighting lamp 53 can accurately illuminate the content on the drawing board 3. Turn on the switch of the lighting lamp 53, adjust the brightness as needed, and start painting.

[0039] In order to facilitate the fixing of the drawing paper on the drawing board 3: the drawing board 3 is symmetrically fixed with a clamping structure 6 for clamping and fixing the top and bottom of the drawing paper respectively, and the clamping structure 6 includes a slide bar 61 symmetrically inserted on the drawing board 3, a U-shaped rod 62 fixedly connected between the two slide bars 61 for clamping and fixing the drawing paper, a baffle 63 fixedly connected to the end of the slide bar 61 away from the U-shaped rod 62, and a spring 64 slidably sleeved on the slide bar 61 between the corresponding baffle 63 and the drawing board 3. The addition of the clamping structure 6 allows the user to easily fix the drawing paper on the drawing board 3 without using other tools such as tape and clips, greatly improving the efficiency and convenience of painting. Through the mutual cooperation of the slide bar 61, the U-shaped rod 62 and the spring 64, the clamping structure 6 can ensure that the drawing paper remains flat and stable during the painting process, avoiding the problem of affecting the painting effect due to shaking or displacement. When using the clamping structure 6 to fix the drawing paper, the drawing paper is laid flat on the drawing board 3 to ensure that it is in the correct position. In the process of adjusting the position of the slide bar 61, the spring 64 will provide a thrust toward the drawing board 3, so that the U-shaped bar 62 can tightly clamp the drawing paper. After the U-shaped bar 62 clamps the drawing paper, the baffle 63 will limit the further sliding of the slide bar 61, thereby ensuring the stability and reliability of the clamping structure 6.

[0040] Furthermore, in order to reduce the wear of the drawing paper by the U-shaped rod 62: a roller 621 is rotatably mounted on the U-shaped rod 62. The addition of the roller 621 effectively reduces the direct contact area between the U-shaped rod 62 and the drawing paper, thereby reducing the degree of wear on the drawing paper. This is of great significance for protecting precious drawing paper and extending its service life. The rotational mounting method of the roller 621 allows the user to more conveniently operate when adjusting the position of the drawing paper or replacing the drawing paper. This not only improves the convenience of drawing, but also reduces the user's operating difficulty and labor intensity.

[0041] In order to facilitate the circular angle adjustment of the drawing board 3 in the main viewing plane: the end of the drawing board 3 close to the support rod 2 is provided with an adjustment structure 2 7 for adjusting the circular angle of the drawing board 3 in the main viewing plane, and the adjustment structure 2 7 includes a fixed ring 71 that is rotatably sleeved on the ball sleeve 42 and fixedly connected to the drawing board 3, a second screw 72 that is threadedly inserted on the fixed ring 71 and conflicts with the ball sleeve 42, and a plum blossom plate 73 that is fixedly connected to the end of the second screw 72 away from the fixed ring 71. The addition of the adjustment structure 2 7 enables the drawing board 3 to easily achieve 360-degree angle adjustment without dead angles. Users can adjust the drawing board 3 to any desired angle according to actual needs, so as to meet different painting needs and creative postures. Through the close conflict between the second screw 72 and the ball sleeve 42, the adjustment structure 2 7 can ensure the stability and reliability of the drawing board 3 during the adjustment process. Even when adjusted to the extreme angle, the drawing board 3 can remain stable and not shake, providing a stable painting platform for the user. The design of the plum blossom plate 73 enables the user to operate more conveniently when adjusting the angle of the drawing board 3. The user only needs to gently rotate the plum blossom plate 73 to quickly adjust and lock the angle of the drawing board 3, which greatly improves the convenience and efficiency of painting. When using the adjustment structure 27 to adjust the angle of the drawing board 3, rotate the plum blossom plate 73 counterclockwise to drive the second screw 72 to rotate and gradually move away from the ball sleeve 42. At this time, the fixed ring 71 and the drawing board 3 will no longer be subjected to the thrust of the second screw 72 and can rotate freely around the ball sleeve 42. Hold the drawing board 3 and adjust its angle to a suitable position as needed. During the adjustment process, the user can gently shake the drawing board 3 to check whether it is stable and does not shake. When the angle of the drawing board 3 is adjusted, rotate the plum blossom plate 73 counterclockwise again to drive the second screw 72 to gradually approach the ball sleeve 42 and generate thrust. When one end of the second screw 72 is in close contact with the ball sleeve 42, the fixed ring 71 and the drawing board 3 will be firmly fixed on the ball sleeve 42 to complete the angle locking.

[0042] Furthermore, in order to facilitate the support of the end of the second screw 72 away from the fixing ring 71: the second screw 72 is rotatably mounted with a support plate 721 fixedly connected to the drawing board 3. The addition of the support plate 721 provides a stable support for the second screw 72, making the adjustment structure 27 more stable and reliable in overall structure. Through the rotational mounting design of the support plate 721 and the second screw 72, the user can save effort and be more convenient when adjusting the angle of the drawing board 3. This design not only reduces the user's operating difficulty and labor intensity, but also improves the efficiency and comfort of painting.

[0043] The above is only a preferred specific implementation manner of the present application, but the protection scope of the present application is not limited thereto. Any technician familiar with the technical field can make equivalent substitutions or changes according to the technical solution and concept of the present application within the technical scope disclosed in the present application, which should be covered by the protection scope of the present application.
