DETAILED DESCRIPTION

[0035] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0036] Example: Figure 1 and Figure 2As shown, a teaching display board that is easy to store includes a bottom plate 1, which can be moved as a whole with a universal wheel 2 at the bottom. When it reaches a suitable position, the internal brake pad can be stepped on to brake it. The counterweight block 10 placed above the bottom plate 1 is used to increase the center of the bottom to improve the stability of the whole during use. The support rod 5 is used to support the display board 6. The multiple groups of mounting holes 7 are used to install physics teaching equipment on the display board 6, so that students can understand physics knowledge more specifically. At the same time, physics theoretical knowledge and principle knowledge of physics teaching equipment can be written on the display board 6 for students to master, and the physics teaching equipment at one end can be used to support the display board 6. In order to improve the teaching effect, when there is a lot of content, the teaching staff can pull the sub-board 9 to both sides, and the multiple groups of rollers 12 at the bottom of the sub-board 9 will move in the roller groove 14 at the lower inner side of the display board 6. At the same time, the slider 11 on the top of the sub-board 9 moves simultaneously in the slide groove 13 at the upper inner side of the display board 6 as it is pulled, so as to pull out the sub-board 9 and ensure its movement stability. After being pulled to a suitable distance, the limiting plate 23 at the end of the sub-board 9 is used to limit the sub-board 9 to prevent the sub-board 9 from sliding out completely. Then the teaching staff can write the content on the sub-board 9, thereby increasing the display area. The tray 8 is used to place items needed for teaching.

[0037] like Figure 1 , Figure 3 and Figure 4 As shown, when the teaching display board is used up, the personnel can first lift the display board 6 upwards, and the multiple groups of plug boards 17 on the back of the display board 6 will simultaneously disengage from the slots 16 in the connecting plate 15, so as to separate the support rod 5 from the display board 6, and then rotate the knob 22 on the surface of the movable ring counterclockwise to cancel the fixation of the movable ring 19. Since the top of the connecting rod 20 is hinged to the movable ring 19 through a hinge, and the bottom is hinged to the fixed ring 18 through a hinge, the personnel can then push the support rod 5 inwards at the same time, so that the two groups of support rods 5 are close to each other along with the universal wheels 2 at the bottom of the bottom plate 1. At the same time, the movable ring 19 will slide upward on the support rod 5 along with the hinge, and the two groups of connecting rods 20 will follow the movable ring through the middle rotating shaft 21. After the folded state, the two groups of positioning rods 3 on the right side of the left bottom plate 1 will enter the two groups of positioning holes 4 on the left side of the right bottom plate 1, and then rotate the knob 22 on the surface of the movable ring 19 clockwise to maintain the firmness after folding, thereby reducing the space occupied when placed.

[0038] Working principle: First, after moving the whole to a suitable position, multiple groups of mounting holes 7 are used to mount physics teaching equipment on the display board 6, so that students can understand physics knowledge more specifically. At the same time, physics theory knowledge and principle knowledge of physics teaching equipment can be written on the display board 6 for students to master, and the physics teaching equipment at one end can be used to improve the teaching effect. When there is a lot of content, the teaching staff can pull the sub-board 9 to both sides, and the multiple groups of rollers 12 at the bottom of the sub-board 9 will move in the roller groove 14 at the lower inner side of the display board 6. At the same time, the slider 11 at the top of the sub-board 9 moves simultaneously in the slide groove 13 at the upper inner side of the display board 6 as it is pulled, so as to pull out the sub-board 9 and ensure its movement stability. , after being pulled to a suitable distance, the limiting plate 23 at the end of the sub-plate 9 is used for limiting processing to prevent the sub-plate 9 from completely sliding out, and then the teaching staff can write the content on the sub-plate 9, thereby increasing the display area. When the whole is idle, the display board 6 can be lifted up first, so that the plug-in board 17 on the back of the display board 6 is disengaged from the slot 16. After taking out the display board 6, the knob 22 is loosened to release the locking state of the movable ring 19, and then the support rod 5 is pressed inwardly at the same time, so that the two sets of connecting rods 20 press the movable ring 19 upward along the rotating shaft 21 therebetween, so that the movable ring 19 moves upward on the support rod. After reaching the appropriate position, the positioning rod 3 is connected to the positioning hole 4 to complete the storage of the whole, thereby reducing the space occupied when idle.

[0039] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art may still modify the technical solutions described in the aforementioned embodiments, or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention shall be included in the protection scope of the present invention.
