[0032] The specific arrangement and function of the rotating device 3 and the unwinding device will be described in detail below.
[0033] like Figure 2 and Figure 3 as well as Figure 4As shown, the rotating device 3 includes a rotating frame 301, which is rotatably connected to the central rod 1, and a plurality of circular holes 302 are opened on the surface of the central rod 1. The surface of the rotating frame 301 is slidably connected with an insertion rod 306, and the insertion rod 306 is slidably connected with the circular hole 302. The surface of the insertion rod 306 is sleeved with a spring 307, and the two ends of the spring 307 are respectively fixedly connected to the insertion rod 306 and the rotating frame 301. The surface of the rotating frame 301 is fixedly connected with a rotating disk 303, and the surface of the rotating frame 301 is fixedly connected with a placement plate 305, which can be When the teacher needs to show drawings to students at different angles, he can contact the limit of the rotating frame 301, and then rotate the rotating frame 301 through the rotating disk 303 to realize the rotation of the placement plate 305 and the drawings, which can facilitate students at different angles to observe and learn, and improve the convenience of drawing display. The surface of the rotating frame 301 is rotatably connected with four rotating beads 310, and the four rotating beads 310 are all slidably connected to the surface of the central rod 1. When the rotating disk 303 is rotated, the rotating beads 310 on the surface of the rotating frame 301 will rotate with the central rod 1. 1 contact, can improve the smoothness of the rotation of the rotating frame 301 as much as possible, so as to facilitate the smooth rotation of the rotating device 3, the surface of the plug rod 306 is rotatably connected with the rotating rod 308, the surface of the rotating frame 301 is provided with a circular groove 309, the rotating rod 308 is slidably connected with the circular groove 309, the plug rod 306 is pulled upward, so that the plug rod 306 is separated from the inside of the circular hole 302, at this time the rotating frame 301 is separated from the limit, and the rotating rod 308 can be further rotated to insert the rotating rod 308 into the inside of the circular groove 309, at this time The insertion rod 306 can be further limited so that the insertion rod 306 will not be reset downward by the action of the spring 307, and the rotating frame 301 can rotate well. The surface of the rotating disk 303 is glued with a plurality of anti-skid sleeves 304, and the plurality of anti-skid sleeves 304 are all made of rubber. The plurality of anti-skid sleeves 304 are arranged in a circular array on the surface of the rotating disk 303. Since the anti-skid sleeves 304 are made of rubber, the friction between the teacher's hand can be increased, which can facilitate the teacher to rotate and adjust, and thus can give a good display to students at different angles.
[0034] like Figure 1 and Figure 5 as well as Figure 6As shown, the unwinding device 4 includes a placement rack 41, the placement rack 41 is fixedly connected to the surface of the placement plate 305, the surface of the placement rack 41 is rotatably connected with a rotating shaft 42, the inner wall of the placement rack 41 is glued with a rubber ring 43, the rotating shaft 42 is rotatably connected to the rubber ring 43, and the surface of the rotating shaft 42 is fixedly connected with a drawing paper 44. When students need to draw, the drawing paper 44 is unrolled through the rotating shaft 42, which further enables students to draw, facilitates students' painting work, does not need to manually change paper, increases the convenience of painting work, and is more convenient and labor-saving to use. The side wall of the placement plate 305 is fixedly connected with an extension plate 45, and the extension plate The surface of 45 is slidably connected with a sliding block 46, and the sliding block 46 is slidably connected to the placement plate 305. The surface of the sliding block 46 is fixedly connected with a blade 47. After the painting is completed, the sliding block 46 can be slid to the blade 47 to quickly cut the drawing paper 44, and the painted drawing paper 44 can be separated, thereby increasing the practicality of the unwinding device 4. The surface of the placement plate 305 is fixedly connected with a limiting plate 48, and the limiting plate 48 is made of elastic material. The limiting plate 48 is in a "V" shape. Since the limiting plate 48 is made of elastic material, it can press the drawing paper 44, and the drawing paper 44 will not move when the students are painting, thereby facilitating the painting.
[0035] Working principle: When the teacher is presenting the drawings, the drawings can be placed on the surface of the placement board 305, and then the students can observe the drawings. When the angle needs to be rotated to present the drawings to different students, the teacher can pull the insertion rod 306 upward to disengage the insertion rod 306 from the circular hole 302. At this time, the rotating frame 301 is out of the limit position, and the rotating rod 308 can be further rotated to insert the rotating rod 308 into the circular groove 309. At this time, the insertion rod 306 can be further limited so that the insertion rod 306 will not be reset downward by the action of the spring 307. The rotating frame 301 can rotate very well, and then the teacher can rotate the rotating frame 301 through the rotating disk 303, so as to drive the drawings placed on the placement plate 305 to rotate. The surface of the rotating disk 303 is glued with an anti-skid cover 304. Since the anti-skid cover 304 is made of rubber, it can increase the friction between the teacher's hand, which can facilitate the teacher to adjust the rotation, and thus can make a good display for students at different angles. When the rotating disk 303 is rotated, the rotating beads 310 on the surface of the rotating frame 301 will contact the central rod 1, which can maximize the rotation. The smoothness of the rotation of the rotating frame 301 facilitates the smooth rotation of the rotating device 3. When the position of the rotating frame 301 needs to be limited, the insertion rod 306 is pulled upward again to make the rotating rod 308 disengage from the inside of the circular groove 309, and then the insertion rod 306 is inserted into the inside of the circular hole 302 under the action of the spring 307. At this time, the rotating frame 301 can be limited, and the placement plate 305 will not rotate. Due to the addition of the spring 307, the insertion rod 306 can be quickly inserted into the circular hole 302 when it is in a vertical position with the circular hole 302. The interior of the rotating frame 301 is realized to achieve stable limiting of the rotating frame 301, and at the same time, the spring 307 drives the insertion rod 306 to move to the position of the circular hole 302, so that the insertion rod 306 is not easy to separate from the circular hole 302, thereby improving the stability of the limiting of the insertion rod 306. By setting a rotating device, when the teacher needs to display drawings to students at different angles, he can contact the limit of the rotating frame 301, and then rotate the rotating frame 301 by rotating the rotating disk 303 to realize the rotation of the placement plate 305 and the drawings, which can facilitate students at different angles to observe and learn, and improve the convenience of displaying drawings.
[0036] When students need to use drawings for drawing, they can pull the drawings, and the pulling force can drive the shaft 42 to rotate, so as to realize the unwinding of the drawing paper 44. Since the contact position between the shaft 42 and the placement frame 41 is the rubber ring 43, the rubber ring 43 will increase the friction between the shaft 42 and the placement frame 41, so that the shaft 42 will not rotate without force. After the drawing paper 44 is unrolled, the drawing paper 44 can be placed in the middle of the limiting plate 48 and the placement plate 305. Since the limiting plate 48 is made of elastic material, it can press the drawing paper 44, so that the drawing paper 44 will not move when the students are drawing, which is convenient. During the painting process, after the painting is completed, the student can slide the sliding block 46, and further drive the blade 47 to cut the drawing paper 44 through the sliding block 46, and can cut the painted part from the entire drawing paper 44, and then take it out. When it is necessary to paint, the drawing paper 44 can be unrolled again without manual replacement. By setting the unwinding device 4, the drawing paper 44 can be unrolled through the rotating shaft 42 when the student needs to paint, and the student can further paint, which facilitates the student's painting work. There is no need to manually change the paper, which increases the convenience of painting work and is more convenient and labor-saving to use.
