Description

Technical Field

[0001] This utility model relates to the field of easel technology, and in particular to an art-designed folding easel. Background Technology

[0002] An easel typically consists of a stand, a canvas clip, and an adjustment mechanism. The stand, usually made of metal or wood, possesses sufficient strength and stability to support canvases of varying sizes and weights. The canvas clip secures the canvas and can be adjusted to fit the canvas's thickness, ensuring it doesn't wobble during painting. The adjustment mechanism allows the painter to adjust the canvas's height and tilt angle according to their height, posture, or painting needs. For example, when painting watercolors, the canvas may need to be tilted at an angle to allow for better paint flow; while when painting oils, the canvas may need to be adjusted to a more vertical position for detailed work. Easels come in a wide variety of types, from portable easels suitable for outdoor sketching—lightweight, easy to fold and carry—to professional studio easels with more robust structures and comprehensive functions, meeting the needs of painters for extended, intensive painting sessions in the studio.

[0003] Existing patent CN111568047A discloses an outdoor art design easel fixing device, including an easel body and an adjustment base. The bottom of the adjustment base is symmetrically provided with a mounting frame, and a moving mechanism is provided inside the mounting frame. One side of the adjustment base is provided with an angle groove, and an angle mechanism is provided inside the angle groove. The other side is provided with a support column. When the prior art starts the angle motor, a first bevel gear rotates. The first bevel gear meshes with a second bevel gear. When the second bevel gear rotates, the angle shaft rotates. An angle block is threadedly connected to the angle shaft. The angle block can move on the angle shaft, driving the angle rod to move, thereby facilitating the adjustment of the tilt angle of the mounting plate.

[0004] However, existing easels do not have a folding function. They are fine for use in fixed indoor locations, but when it is necessary to move them outdoors for painting, their large size makes them difficult to carry quickly and conveniently to the outdoor environment, thus limiting the scope of painting activities. Utility Model Content

[0005] The purpose of this utility model is to provide an art design folding easel, which aims to solve the technical problem that existing easels do not have a folding function. They are acceptable for use in fixed indoor locations, but when it is necessary to move them outdoors for painting, their large size makes them difficult to carry quickly and conveniently to the outdoor environment, thus limiting the expansion of painting activities.

[0006] To achieve the above objectives, this utility model employs an art design folding easel, comprising a rear support and a front support. The rear support is equipped with a support rod, on which two driven gears are mounted. Two support blocks are positioned above the front support, and a rotating rod is rotatably connected between the two support blocks via a bearing. The rotating rod is equipped with two driving gears, and a worm gear is mounted at one end of the rotating rod. A mounting box is located on one side of the front support, with the worm gear extending into the mounting box. A worm is rotatably mounted within the mounting box, meshing with the worm gear and positioned below it. The rear support is hinged to the front support via the support rod and is located inside the front support. The two driving gears mesh with their corresponding driven gears and are positioned above them.

[0007] A protective cover is fitted between the driving gear and the driven gear. The support rod and the rotating rod both pass through both sides of the protective cover, and the protective cover between the two driving gears and the two driven gears is connected by a support rod.

[0008] Multiple anti-slip pads are provided under both the rear bracket and the front bracket.

[0009] The art design folding easel also includes two supporting components, which are fixedly connected to the front support and symmetrically arranged on the front end face of the front support.

[0010] The lifting assembly includes a fixing block and a lifting block. The fixing block has a locking threaded groove, and a locking screw is threaded into the locking threaded groove. The lifting block has a pressing threaded groove, and a pressing screw is threaded into the pressing threaded groove. A convex block is provided below the lifting block. The front end face of the front bracket has two convex grooves. The fixing block is fixedly connected to the lifting block and is located on the lower end face of the lifting block. The lifting block is slidably connected to the front bracket through the convex block and is located on the front end face of the front bracket. The convex block is located in the corresponding convex groove. The locking screw abuts against the front bracket and is located at the inner bottom of the corresponding convex groove.

[0011] This utility model discloses an art design folding easel, comprising a rear support and a front support. The rear support has a support rod with two driven gears. The front support has two support blocks on its upper surface, and a rotating rod rotatably connects the two support blocks via bearings. The rotating rod has two driving gears and a worm gear at one end. A mounting box is located on one side of the front support, and a worm gear rotatably connects within the mounting box. In this design, the rear support is hinged to the front support via the support rod and is located inside the front support. This hinged structure allows the easel to fold, changing its shape. By reducing its size and making it easy to carry, the worm gear and worm wheel achieve self-locking of the driving gear and the driven gear, thereby preventing changes in the adjusted angle. At the same time, it can be quickly and conveniently carried to the outdoor environment, overcoming the problem that the large size of existing easels limits the expansion of painting activities. This method solves the technical problem that existing easels do not have a folding function, are suitable for use in fixed indoor locations, but are difficult to carry quickly and conveniently to the outdoor environment when painting needs to be moved, thus limiting the expansion of painting activities.

Detailed Implementation

[0021] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0022] Please see Figures 1 to 7 This utility model provides an art design folding easel, including a rear support 1 and a front support 2. The rear support 1 is provided with a support rod 3, and the support rod 3 is provided with two driven gears 4. The front support 2 has two support blocks 5 above it, and a rotating rod 6 is rotatably connected between the two support blocks 5 via a bearing. The rotating rod 6 is provided with two driving gears 7, and a worm gear 8 is provided at one end of the rotating rod 6. A mounting box 9 is provided on one side of the front support 2, and the worm gear 8 extends into the mounting box 9. A worm 10 is rotatably installed inside the mounting box 9, meshing with the worm gear 8 and located below the worm gear 8. The rear support 1 is hinged to the front support 2 via the support rod 3 and is located inside the front support 2. The two driving gears 7 respectively mesh with the corresponding driven gears 4 and are located above the driven gears 4.

[0023] In this embodiment, the rear support 1 is hinged to the front support 2 via the support rod 3 and is located inside the front support 2. This hinge structure allows the easel to be easily folded, greatly reducing its size and making it easy to carry and store. At the same time, the driving gear 7 on the rotating rod 6 meshes with the driven gear 4 on the support rod 3. In conjunction with the worm gear 8 and the worm 10 structure, the angle between the front support 2 and the rear support 1 can be easily adjusted to meet the needs of different painting postures and scenarios, thereby improving the practicality and applicability of the easel.

[0024] Furthermore, a protective cover 11 is fitted between the driving gear 7 and the driven gear 4, and the support rod 3 and the rotating rod 6 both pass through both sides of the protective cover 11. The protective cover 11 between the two driving gears 7 and the two driven gears 4 is connected by a support rod 12.

[0025] In this embodiment, the protective cover 11 provides good protection. It prevents dust and debris from entering the gear meshing part, avoids wear or damage to the gear due to external contamination, extends the service life of the gear, and thus ensures the stability and reliability of the easel's angle adjustment function, improving the overall quality of the easel. At the same time, since the protective cover 11 is sleeved on the driving gear 7 and the driven gear 4, it does not rotate with the rotating rod 6 and the support rod 3.

[0026] Furthermore, multiple anti-slip pads 13 are provided below both the rear bracket 1 and the front bracket 2.

[0027] In this embodiment, the anti-slip pads 13 effectively prevent the easel from sliding or tipping over, providing the painter with a stable and safe painting platform.

[0028] Furthermore, the art design folding easel also includes two supporting components, which are respectively fixedly connected to the front support 2 and symmetrically arranged on the front end face of the front support 2.

[0029] Further, the lifting assembly includes a fixing block 14 and a lifting block 15. The fixing block 14 has a locking threaded groove 16, and a locking screw 17 is provided in the internal thread of the locking threaded groove 16. The lifting block 15 has a pressing threaded groove 18, and a pressing screw 19 is provided in the internal thread of the pressing threaded groove 18. A convex block 20 is provided below the lifting block 15. The front end face of the front bracket 2 has two convex grooves 21. The fixing block 14 is fixedly connected to the lifting block 15 and is located on the lower end face of the lifting block 15. The lifting block 15 is slidably connected to the front bracket 2 through the convex block 20 and is located on the front end face of the front bracket 2. The convex block 20 is located in the corresponding convex groove 21. The locking screw 17 abuts against the front bracket 2 and is located at the inner bottom of the corresponding convex groove 21.

[0030] In this embodiment, the lifting block 15 is slidably connected to the front support 2 via the convex block 20. This structure allows the lifting block 15 to slide flexibly on the front end face of the front support 2, making it convenient to adjust the lifting position according to the size and shape of the drawing tool. The locking screw 17 abuts against the bottom of the convex groove 21. The locking screw 17 is provided in the locking thread groove 16, which can firmly fix the position of the lifting block 15 and ensure that the lifting assembly will not slide arbitrarily during the drawing process. The clamping screw 19 is provided in the clamping thread groove 18, which can further fix the drawing tool placed on the lifting assembly, preventing the drawing tool from shaking or falling during the drawing process, and improving the stability and safety of the easel for supporting the drawing tool.

[0031] When using this utility model, first unfold the rear bracket 1 and the front bracket 2, then rotate the worm gear 10 inside the mounting box 9 clockwise. The worm gear 10 drives the worm wheel 8 to rotate, which in turn causes the rotating rod 6 to rotate. The driving gear 7 on the rotating rod 6 rotates accordingly. The driving gear 7 meshes with the driven gear 4, thereby adjusting the angle between the front bracket 2 and the rear bracket 1. The worm gear 10 and the worm wheel 8 ensure that the adjusted angle does not change, thus meeting the needs of different drawing postures and scenes. Then, slide the convex block 20 in the convex groove 21 on the front end face of the front bracket 2 to adjust it to a suitable position. Finally, tighten the lock in the locking thread groove 16. Tighten screw 17 so that it abuts against the front bracket 2, fixing the position of the lifting block 15. Then place the painting tool on the lifting block 15 and tighten the clamping screw 19 in the clamping thread groove 18 to further fix the painting tool. Painting can then begin. After painting is finished, control the worm gear 10 to rotate counterclockwise to fold the rear bracket 1 and the front bracket 2 together, reducing the volume and making it easier to carry and store. This method solves the technical problem that existing easels do not have a folding function. They are acceptable for use in fixed indoor locations, but when it is necessary to move them to the outdoors for painting, their large size makes it difficult to carry them quickly and conveniently to the outdoor environment, thus limiting the expansion of painting activities.

[0032] The above-disclosed embodiments are merely preferred embodiments of the present utility model and should not be construed as limiting the scope of the present utility model. Those skilled in the art can understand that implementing all or part of the above-described embodiments and making equivalent changes in accordance with the claims of the present utility model are still within the scope of the utility model.
