Description

Technical Field

[0001] The utility model relates to the technical field of creative easels, and more specifically, to an auxiliary easel for literary and artistic creation. Background Art

[0002] With the development of the times and the advancement of technology, watercolor painting has gradually faded out of people's sight. People have begun to accept more forms of art such as cartoons and simple drawings. Also, because watercolor painting is difficult to create, difficult to grasp, and once mistakes are made, it must be recreated, people only have an appreciative attitude towards the completed watercolor paintings, which is very detrimental to the development and inheritance of the art of watercolor painting.

[0003] Existing easels are mainly composed of a supporting structure and a drawing board. The supporting structure is mostly foldable, and the drawing board is mostly detachable, which makes them particularly portable when used outdoors. However, in fact, strong winds are often encountered outdoors, and most existing easels are triangular supports. The easel triangle is mostly placed directly on the ground and lacks a fixed structure. When strong winds come, it is easy to cause the slide to tip over, resulting in painting failure. Therefore, it needs to be improved. Utility Model Content

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0021] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0022] Such as Figures 1 to 4As shown in the figure, the utility model provides an auxiliary easel for literary creation, which includes two main brackets 1 on the left and right. Two upper and lower support rod frames 2 are connected to the back of the two main brackets 1. A secondary bracket 3 is movably connected to the back of the support rod frame 2, and a locking mechanism 4 is connected to the lower end of the secondary bracket 3; on the front of the two main brackets 1, a support block 5 is fixedly connected, and a drawing board 6 is placed on the front of the two main brackets 1 and on top of the two support blocks 5;

[0023] The locking mechanism 4 includes a positioning insertion rod 41 fixedly connected to the bottom of the secondary bracket 3. The lower end of the positioning insertion rod 41 is conical. A control component 42 is arranged at the upper end of the positioning insertion rod 41. A sealing cavity 45 is formed inside the positioning insertion rod 41 and is located inside the control component 42. A positioning convex part 43 is sleeved inside the positioning insertion rod 41 and is located below the control component 42. The outer surface of the positioning convex part 43 is smoothly connected to the outer surface of the positioning insertion rod 41. A through hole 44 is formed inside the positioning insertion rod 41 and is located inside the positioning convex part 43 and communicates with the bottom of the sealing cavity 45. The side of the through hole 44 communicates with the inside of the positioning convex part 43; the outer surface of the positioning convex part 43 is smooth, and the cross section of the positioning convex part 43 is uneven; due to the setting of the positioning insertion rod 41, it is convenient for the user to connect and fix the lower end of the positioning convex part 43 to the ground, effectively reducing the probability of the sliding frame tipping over when strong winds come. And because the outer surface of the positioning convex part 43 is uneven after expansion, the connection resistance with the soil can be increased, effectively reducing the probability of the positioning insertion rod 41 shaking and being pulled out, thus effectively improving the stability of the sliding frame.

[0024] Among them, the main bracket 1 includes a bracket body 11 connected to both ends of the support rod frame 2. A positioning groove 12 and a positioning hole 14 are formed on the back of the bracket body 11. A limiting groove 13 and a limiting hole 15 are formed inside the bracket body 11 and are located in front of the positioning groove 12 and the positioning hole 14 respectively. The limiting groove 13 communicates with the positioning groove 12, and the limiting hole 15 communicates with the positioning hole 14. The inner diameters of the limiting groove 13 and the limiting hole 15 are respectively larger than the inner diameters of the positioning groove 12 and the positioning hole 14; due to the setting of the positioning groove 12, etc., the first support rod 21 can slide along the back of the bracket body 11, so as to achieve the effect of supporting the two bracket bodies 11 and facilitating folding. And the setting of the second support rod 22 will neither affect the folding and storage of the two first support rods 21, nor is it convenient for the support of the secondary bracket 3. Moreover, the secondary bracket 3 can provide good support for the two first support rods 21 through the second support rod 22, avoiding the situation that the two bracket bodies 11 approach each other due to their reverse swing, thus effectively improving the stability of the sliding frame after unfolding.

[0025] Among them, the support rod frame 2 includes a first support rod 21 connected to the back of the bracket body 11. One end of the first support rod 21 is connected to the positioning hole 14 and the limiting hole 15 through a cam, and the other end of the first support rod 21 is connected to the positioning groove 12 and the limiting groove 13 through a cam.

[0026] Wherein, convex shafts are connected to the facing surfaces of the two first support rods 21. A second support rod 22 is further arranged between the two first support rods 21. The two ends of the second support rod 22 are movably sleeved on the upper and lower convex shafts. A hinge block 23 is connected to the back of the second support rod 22. The upper end of the auxiliary support 3 is hinged to the hinge block 23.

[0027] Wherein, the control assembly 42 includes an adjusting ring 421 threadedly sleeved on the outer surface of the positioning plug 41. A linkage ring 422 sleeved on the outside of the positioning plug 41 is arranged at the top of the adjusting ring 421. A rotating clamping ring is movably sleeved at the bottom of the linkage ring 422. The bottom of the rotating clamping ring is fixedly connected to the top of the adjusting ring 421. Due to the arrangement of the rotating clamping ring, it is ensured that when the adjusting ring 421 moves up and down along the outside of the positioning plug 41, the linkage ring 422 can be driven to move up and down, and when the adjusting ring 421 rotates, the linkage ring 422 will not be driven to rotate.

[0028] Wherein, a linkage shaft 423 located inside the linkage ring 422 is movably sleeved inside the sealing cavity 45. A connecting rod 425 is fixedly connected to the bottom of the linkage shaft 423. A piston 426 is fixedly connected to the bottom of the connecting rod 425. The piston 426 is sealingly sleeved inside the sealing cavity 45. Due to the arrangement of the connecting rod 425, the linkage shaft 423 can drive the piston 426 to move up and down, and it can be ensured that the connecting rod 425 is always located below the sliding groove 46.

[0029] Wherein, a plurality of sliding grooves 46 which are evenly distributed and located between the linkage ring 422 and the linkage shaft 423 and above the piston 426 are formed on the outer surface of the positioning plug 41. A linkage slider 424 is slidably clamped inside the sliding groove 46. One side of the linkage slider 424 penetrates through the sliding groove 46 and extends to the outside of the positioning plug 41 and is fixedly connected to the inside of the linkage ring 422. The other side of the linkage slider 424 penetrates through the sliding groove 46 and extends to the inside of the sealing cavity 45 and is fixedly connected to the outer surface of the linkage shaft 423.

[0030] The working principle and usage process of the present utility model:

[0031] Pulling the two bracket bodies 11 can expand them and enable the two first support rods 21 to support the two bracket bodies 11 in cooperation with the positioning grooves 12, positioning holes 14, etc. Then, the second support rod 22 is sleeved on the convex block between the two first support rods 21. At this time, the two bracket bodies 11 move away from each other, and the support blocks 5 on their fronts can support the drawing board 6.

[0032] Then expand the auxiliary support 3 so that its lower end and the lower ends of the two support bodies 11 are respectively located at the three vertices of a triangle. Then insert the lower end of the positioning insertion rod 41 into the ground. Then rotate the adjusting ring 421 so that it moves downward under the cooperation of the thread on the surface of the positioning insertion rod 41. Furthermore, driven by the cooperation of the rotating clamping ring and the limitation of the chute 46 and the linkage slider 424, the linkage ring 422 moves downward. Then, the piston 426 can be pushed through the linkage shaft 423 and the connecting rod 425 so that it moves downward along the inner wall of the sealing cavity 45. Thus, the air in the sealing cavity 45 can be pressed into the inside of the positioning convex part 43 through the through hole 44, causing the positioning convex part 43 to expand and expand outwards;

[0033] Since the upper and lower thicknesses of the positioning convex part 43 are different, the expansion efficiency under the same pressure is also different. Therefore, the outer surface of the expanded and expanded positioning convex part 43 can be uneven, so that its abutment with the surrounding soil is more stable, effectively avoiding the situation that the locking mechanism 4 is pulled out due to the shaking of the sliding frame.
