[0024] In order to make the purpose, technical scheme and advantages of the embodiments of the present application clearer, the technical scheme in the embodiments of the present application is clearly and completely described below. Obviously, the described embodiments are 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 also fall within the scope of protection of the present application.

[0025] like Figure 1-Figure 3 As shown, a color adjustment auxiliary device for art teaching disclosed in the present application includes a vertically arranged mounting base plate 1, a plurality of color disks 2 are arranged on the front side of the mounting base plate 1, the plurality of color disks 2 are arranged in a line on the front side of the mounting base plate 1, and a plurality of fan-shaped color areas 3 are evenly divided on the side of each color disk 2 away from the mounting base plate 1; an indication mark 4 is respectively provided on the mounting base plate 1 directly below the plurality of color disks 2; the plurality of color disks 2 are respectively mounted on the mounting base plate 1 through a rotating unit 5, a linkage assembly 6 is provided on the back side of the mounting base plate 1, and the plurality of rotating units 5 are all connected to the linkage assembly 6; when one of the color disks 2 rotates, the other color disks 2 can be rotated synchronously through the linkage assembly 6.

[0026] In the above embodiments, color matching is often required when painting, and some basic colors are arranged and combined and mixed together in different proportions to form various colors, so as to draw rich paintings. However, in the process of painting, beginners of painting often need to frequently refer to color cards to find out which colors they need to make up, and then find out the basic colors from the toolbox to mix and match them. A painting often requires applying multiple colors. If beginners of painting frequently repeat the above operations, the efficiency of painting will be greatly reduced. Especially in the teaching process, it is easy to lag behind the teacher in one step, which will cause the following steps to be unable to keep up, which can easily affect the confidence of beginners in learning painting.

[0027] The present application is provided with a plurality of color disks 2 on the front side of the mounting substrate 1, wherein the colors distributed on each fan-shaped color area 3 on the color disk 2 at one end are the colors that the painter generally needs to mix during the painting process. For the convenience of understanding, the color disk 2 is referred to as the main color disk 2, and the remaining color disks 2 are referred to as sub-color disks 2. Different colors are also marked in each fan-shaped color area 3 on these sub-color disks 2, and each fan-shaped color area 3 on these sub-color disks 2 corresponds one by one to the multiple fan-shaped color areas 3 on the main color disk 2. Since the rotating units 5 on all the color disks 2 are connected to the same linkage component 6, when the main color disk 2 is rotated, the other sub-color disks 2 can be rotated synchronously through the linkage component 6. When a beginner wants to use a color that needs to be mixed during the painting process, he can find the fan-shaped color area 3 where the color is located on the main color disc 2, and then rotate the main color disc 2 so that the rotating fan-shaped color area 3 on the main color disc 2 is facing the indicator mark 4 below. At this time, the remaining sub-color discs 2 will rotate synchronously, and the colors on the fan-shaped color areas 3 facing the respective indicator marks 4 below are exactly the basic colors that constitute the color required by the painter. Next, the painter only needs to take out the corresponding pigment according to the color of the fan-shaped color area 3 corresponding to the respective indicator marks 4 below on each sub-color disc 2, and then mix them according to the proportion. In this way, when the beginner needs a color during the painting process, he only needs to quickly rotate the main color disc 2 to align the required color with the indicator mark 4 below, and then select the pigment according to the color on the fan-shaped color area 3 of each sub-color disc 2 facing the upper part of the indicator mark 4 for mixing. The operation is convenient and fast, and the time for mixing colors during the painting process of the painting beginner can be effectively shortened, thereby avoiding the beginner from not being able to keep up with the teacher's teaching rhythm and affecting his interest in learning painting.

[0028] During actual teaching, teachers and students can use the color mixing auxiliary device together. When the teacher is teaching the color selection of paintings on the podium, he can demonstrate through the color mixing auxiliary device. The demonstration process is the same as above. This makes it more vivid for students to understand, and it is also convenient for students to quickly imitate the teacher on their own color mixing auxiliary devices, thereby improving the efficiency and quality of teaching and learning.

[0029] Furthermore, if Figure 1-Figure 3 As shown, there are three color discs 2 , wherein two adjacent color discs 2 are provided with pigment bins 7 on the side close to the mounting substrate 1 , and an anti-slip ring 8 is provided on the outer fixed sleeve of the other color disc 2 .

[0030] In the above embodiments, for beginners of painting, most of the colors they use for color matching are some basic colors, which are mostly mixed from two colors, such as pink is mixed from red and white, orange is mixed from red and yellow, and green is mixed from yellow and blue. Some complex colors are difficult for beginners of painting, and they are usually learned only after they have mastered the mixing of basic colors. For example, the further expansion of some basic color systems, such as the yellow-gray in the gray system, is obtained by mixing flesh color, lemon yellow, white and sky blue in proportion. This color is obviously more complex and not suitable for beginners. Therefore, the present application sets the number of color discs 2 to three, one of which is located at the edge as the main color disc 2, and the other two adjacent color discs 2 are sub-color discs 2. The multiple sector-shaped color areas 3 on the main color disc 2 are respectively marked with some basic colors that need to be mixed and are often used by beginners of painting, and the sector-shaped color areas 3 of the other two sub-color discs 2 are respectively marked with basic colors that can be used to mix the colors at the corresponding positions on the main color disc 2. In order to make it easier for painting beginners to identify which is the sub-color disk 2 and which is the main color disk 2, a "+" sign can be set in the area between two sub-color disks 2 on the mounting substrate 1, and a "=" sign can be set in the area between the main color disk 2 and an adjacent sub-color disk 2.

[0031] After a beginner in painting moves the fan-shaped color area 3 of the desired color on the main color disc 2 to the top of the corresponding indicator mark 4, the basic colors of the color on the two sub-color discs 2 can be automatically aligned with the indicator marks 4 below them. If a beginner in painting wants to continue to adjust the color, he or she needs to find the pigment corresponding to the corresponding basic color on the sub-color disc 2 in the tool box or stationery bag. The process of finding will also increase the time for the painter to paint. The pigment bin 7 is placed on the back of the two sub-color discs 2, which can facilitate the painter to quickly find the desired pigment and complete the color adjustment operation. The anti-slip dial ring 8 arranged on the outside of the main color disc 2 facilitates the painter to quickly and accurately adjust the main color disc 2 to rotate the desired color to the indicator mark 4.

[0032] Furthermore, if Figure 3 As shown, the rotating unit 5 includes a bearing 51 mounted on the mounting substrate 1, a fixed sleeve 52 is penetrated through the inner ring of the bearing 51 and the two are fixedly connected, a rotating shaft 53 is fixedly inserted into the inner side of the fixed sleeve 52, one end of the rotating shaft 53 is fixedly connected to the side of the color disc 2 close to the mounting substrate 1 through a flange 54, and the other end of the rotating shaft 53 is connected to the linkage assembly 6.

[0033] In the above embodiments, a through mounting hole is provided at a position corresponding to each color disk 2 on the mounting substrate 1 of the present application, and the bearings 51 in each rotating unit 5 are fixedly installed in each mounting hole. The rotatable inner ring of the bearing 51 is connected to the fixed sleeve 52, and the rotating shaft 53 is fixedly inserted in the fixed sleeve 52. One end of the rotating shaft 53 is firmly connected to the corresponding color disk 2 through the flange 54, so that when the painter rotates the color disk 2, the rotation process can be sufficiently labor-saving and smooth.

[0034] Furthermore, if Figure 3 As shown, the linkage assembly 6 includes a transmission shaft 61, on which a plurality of brackets 62 are rotatably sleeved, and the plurality of brackets 62 are fixedly connected to the rear side of the mounting substrate 1; the transmission shaft 61 is fixedly sleeved with a plurality of first bevel teeth 63 equal in number to the color disc 2, and each first bevel tooth 63 is meshed with a second bevel tooth 64 on a side close to the mounting substrate 1, and the plurality of second bevel teeth 64 are respectively fixedly connected to the ends of the plurality of rotating shafts 53 away from the color disc 2.

[0035] In the above embodiment, the transmission shaft 61 is movably mounted on the rear side of the mounting base 1 through the bracket 62. The bracket 62 can not only provide the necessary supporting force for the transmission shaft 61 through the mounting base 1 but also ensure that the transmission shaft 61 can rotate freely around its own axis. The rotating shaft 53 behind each color disk 2 is connected with a second bevel tooth 64, and each first bevel tooth 63 is respectively meshed with multiple first bevel teeth 63 on the transmission shaft 61 one by one. In this way, when one of the color disks 2 rotates, the second bevel tooth 64 on its rear side can rotate with the transmission shaft 61 through the corresponding first bevel tooth 63, and the remaining first bevel teeth 63 on the transmission shaft 61 will also rotate accordingly. The corresponding second bevel teeth 64 matching the remaining first bevel teeth 63 will also rotate synchronously with the corresponding color disk 2, thereby achieving the effect of synchronous rotation of all color disks 2, effectively improving the convenience of the use process of this application.

[0036] Furthermore, if Figure 1 and Figure 2 As shown, the paint bin 7 includes a mounting base 71 fixedly mounted on the corresponding color disc 2 near the mounting substrate 1, and the mounting base 71 is evenly provided with a plurality of through threaded holes 72 along the circumferential direction, and the positions of the plurality of threaded holes 72 in the circumferential direction of the mounting base 71 correspond one by one to the positions of the fan-shaped color areas 3 on the color disc 2, and a paint bottle 73 is provided in each through threaded hole 72 and the two are threadedly connected.

[0037] In the above embodiment, the number of threaded holes 72 on the mounting base 71 is equal to the number of sector-shaped color areas 3 on the corresponding color disc 2. A paint bottle 73 is installed in each threaded hole 72. Each paint bottle 73 contains paint of the same color as the corresponding sector-shaped color area 3 on the color disc 2. When the painter finds the required color on the color disc 2, he can directly take out the corresponding paint bottle 73 at the corresponding position in the mounting base 71 on the back of the color disc 2. The color of the paint in the paint bottle 73 is the basic color required for the painter to mix the required color, which can further improve the painter's painting efficiency.

[0038] Furthermore, if Figure 1 and Figure 4 As shown, a front protective shell 9 which can be freely opened downward is provided on the front side of the mounting substrate 1, and when the front protective shell 9 is opened, its front panel is coplanar with the lower end of the mounting substrate 1; a rear protective shell 10 is provided on the upper half of the rear side of the mounting substrate 1, and the rear protective shell 10 covers the outer side of the linkage assembly 6.

[0039] In the above embodiment, the depth of the front protective shell 9 of the present application is sufficient to protect the plurality of color disks 2 when it is buckled on the mounting substrate 1. In addition, after the front protective shell 9 is opened (i.e., the front panel of the front protective shell 9 and the mounting substrate 1 form a 90° angle), the front panel of the front protective shell 9 and the lower end of the mounting substrate 1 are coplanar (the state after opening can be referred to Figure 1 ), so that the interior of the front protective shell 9 after opening can form a flat area, and the painter can use it to place the palette or other painting tools to avoid contaminating the desktop when mixing colors directly on the desktop. The rear protective shell 10 set on the rear side of the mounting base 1 of the present application plays a good protective role for the linkage component 6 to prevent it from being affected by the external environment.

[0040] Furthermore, if Figure 1 and Figure 4 As shown, when the front protective shell 9 is closed upward on the mounting substrate 1 , the top of the front protective shell 9 and the top of the rear protective shell 10 can be detachably fixed by means of the buckle 11 .

[0041] In the above embodiment, when the front protective shell 9 of the present application is buckled on the mounting substrate 1, it is fixed to the rear protective shell 10 by the buckle 11, so that the front protective shell 9 can be stably covered outside the plurality of color disks 2 to provide them with dust-proof protection, and it is also convenient to store the color adjustment auxiliary tool. Since the front protective shell 9 and the rear protective shell 10 are connected by the buckle 11, it is also quick and convenient to open the front protective shell 9 in subsequent use.

[0042] Furthermore, if Figure 1 As shown, an adjustable support frame 12 is movably mounted on the rear side of the mounting base plate 1 below the rear protective shell 10 .

[0043] In the above embodiments, whether it is a teacher or a student using the color adjustment auxiliary device of the present application during the painting process, the entire mounting substrate 1 can be propped up by the adjustable support frame 12. When the teacher uses it, it is convenient to show the students the selection of colors on the mounting substrate 1 on the podium, and the students do not need to lower their heads when using it, and can follow the teacher to complete the color selection, which makes it easier for students to keep up with the teacher's pace when learning painting courses.

[0044] Furthermore, if Figure 1 As shown, a handle 13 is installed on the top of the front protective shell 9 close to the mounting base plate 1.

[0045] In the above embodiment, the handle 13 provided on the front protective shell 9 in the above manner is convenient for teachers or students to take away the color adjustment auxiliary device of the present application after using it.

[0046] The implementation principle of this embodiment is: no matter whether it is a teacher or a student, when using the color adjustment auxiliary device of this application, first open the buckle 11 between the front protective shell 9 and the rear protective shell 10, then open the front protective shell 9, and open the adjustable support frame 12 under the rear protective shell 10 to start painting.

[0047] When a student who is just learning to paint or a teacher needs to teach painting to a student, they can directly rotate the color disc 2 with the anti-skid dial ring 8 to make the fan-shaped color area 3 of the color disc 2 with the desired color face the indicator mark 4 below. Since the color disc 2 will rotate with the rotating shaft 53 behind it, the rotating shaft 53 will rotate with the corresponding first bevel gear 63 on the transmission shaft 61 through the second bevel gear 64 connected thereto, and the first bevel gear 63 will rotate with the other first bevel gears 63 after driving the transmission shaft 61 to rotate, so that the second bevel gears 64 corresponding to the other first bevel gears 63 will rotate with the color disc 2 with the anti-skid dial ring 8 connected thereto, and the colors on the fan-shaped color areas 3 facing the indicator marks 4 below them when the color disc 2 with the anti-skid dial stops are the basic colors that constitute the colors required by the painter. At this time, the beginner painting student takes the paint bottle 73 of the corresponding basic color from the back of each corresponding color disk 2, and mixes the color according to the proportion on the palette to obtain the desired color, which effectively improves the effect of the teacher teaching painting and the efficiency of the students learning painting.

[0048] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit it. Although the present application has been described in detail with reference to the aforementioned embodiments, ordinary technicians in the field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present application.
