[0006] The above-mentioned patents still have the following shortcomings in practice:

[0007] When the aforementioned patent is used for teaching, the liquid inside the water tank can be injected into the inner cavity of the transparent water pipe by a water pump, and the economic data can be displayed by the height of the water droplets. Although this can achieve the purpose of demonstration and teaching, a water pump needs to be installed after each water pipe, which greatly increases the operating cost and makes the device less practical. Utility Model Content

[0008] The main purpose of this invention is to provide a chart teaching device for industrial economics that can effectively solve the problem that chart teaching devices cannot be raised or lowered.

[0009] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0027] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0028] like Figure 1 , Figure 2 and Figure 3 As shown, a chart teaching device for industrial economics includes a base 1, a lifting device 2 fixedly connected to the upper middle part of the base 1, a fixed block 6 fixedly connected to the upper part of the lifting device 2, a push rod 4 fixedly connected to the rear end of the fixed block 6, a rotating device 7 rotatably connected to the front middle part of the fixed block 6, a display board 3 fixedly connected to the front of the rotating device 7, a coloring board 8 installed at the front middle part of the display board 3, and a chart teaching mechanism 5 fixedly connected to the upper end of the display board 3.

[0029] The base 1 of this device is fixedly connected to four corners of its lower end with self-locking casters, which can move the device.

[0030] In the above process, the device is moved to the teaching position by push rod 4, and then the device is fixed by self-locking casters.

[0031] In the above, after the device is fixed in place, the display board 3 can be raised or lowered by rotating the lifting device 2, so that the height of the display board 3 can ensure that each student can clearly see the content on the chart teaching mechanism 5 without having to look up or down for a long time, thereby reducing the pressure on the neck and back. When demonstration teaching is required, the chart teaching mechanism 5 can be twisted to display the information through water, and then the information can be displayed more clearly through the coloring board 8.

[0032] As described above, after the demonstration is completed, the water on the chart teaching device 5 needs to be returned to its original position so that the device can be used for the next teaching demonstration. At this time, simply rotate the display board 3. The display board 3 rotates at the front end of the fixed block 6 through the rotating device 7. After rotating the display board 3 to 180 degrees, the rotating device 7 fixes the display board 3, and then the water is returned to its original position so that the device can be used for the next teaching demonstration.

[0033] As described above, the coloring panel 8 can make the information displayed on the chart teaching institution 5 clearer, because water is colorless and transparent, and the coloring panel 8 can make the information about water on the chart teaching institution 5 clearer.

[0034] Furthermore, in order to achieve the purpose of lifting and lowering the display panel 3 using the rotating lifting device 2, refer to... Figure 4 The lifting device 2 includes a support shell 21, which is fixedly connected to the middle of the upper end of the base 1. A threaded rod 22 is threadedly connected to the middle of the support shell 21. A sliding shell 23 is slidably connected to the outer ring inside the support shell 21. A bevel gear set 25 is fixedly connected to the bottom wall of the inner cavity of the sliding shell 23. A rocker arm 24 is fixedly connected to the input end of the bevel gear set 25.

[0035] The upper part of the outer surface of the threaded rod 22 is fixedly connected to the output end of the bevel gear set 25.

[0036] In the above process, by rotating the rocker arm 24, the input end of the bevel gear set 25 is rotated. When the output end of the bevel gear set 25 rotates, power is transmitted to its output end, causing it to rotate. The output end of the bevel gear set 25 then drives the threaded rod 22 to rotate. When the threaded rod 22 rotates, it continues to move upward through its threaded connection with the support shell 21. When the threaded rod 22 moves upward, it drives the sliding shell 23 to move upward as well. The sliding shell 23 then drives the fixed block 6 to move upward. When the fixed block 6 moves upward, it drives the display plate 3 to move upward through the rotating device 7, thereby achieving the purpose of adjusting the height of the display plate 3.

[0037] Furthermore, in order to achieve the purpose of fixing the display panel 3 after it is rotated by the rotating device 7, refer to... Figure 5The rotating device 7 includes a rotating ring 71 and two telescopic shells 72. The rotating ring 71 is rotatably connected to the middle of the front end of the fixed block 6. Arc-shaped grooves 75 are provided on the upper and lower sides of the rear part of the outer surface of the rotating ring 71. The two telescopic shells 72 are symmetrically fixedly connected to the middle of the upper and lower front end of the fixed block 6. Friction rods 74 are slidably connected to the inner cavity of the two telescopic shells 72. A telescopic spring 73 is fixedly connected between the wall of the two telescopic shells 72 that is far apart from each other and the end of the two friction rods 74 that is far apart from each other.

[0038] The friction rod 74 located on one side is in contact with the arc-shaped groove 75 on the same side.

[0039] In the above description, when the display panel 3 is rotated, it rotates on the fixed block 6 via the rotating ring 71. When the rotating ring 71 rotates, it will drive the arc groove 75 to rotate as well. At this time, the tension generated by the rotating ring 71 will drive the two friction rods 74 to continue to move away from each other and squeeze the telescopic spring 73 to generate pressure. When the display panel 3 rotates 180 degrees via the rotating ring 71, the arc groove 75 located at the lower part will rotate to the upper part. At this time, the telescopic spring 73 will release the pressure and push the two friction rods 74 to move closer to each other, so that the friction rods 74 re-fit the arc groove 75, thereby achieving the purpose of fixing.

[0040] In the above, after the display board 3 rotates 180 degrees, the water used for display on the display board 3 will flow back to its original position, allowing the display board 3 to be used for the next teaching demonstration.

[0041] Furthermore, in order to enable the teaching institution 5 to continue presenting the teaching through the coloring palette 8, see [reference needed]. Figure 6 The chart teaching unit 5 includes a T-shaped frame 56, which is fixedly connected to the upper end of the display board 3. A water cylinder 51 is fixedly connected to the middle of the upper end of the T-shaped frame 56. A water outlet pipe 52 is fixedly connected to the water outlet of the water cylinder 51. Several connecting pipes 53 are fixedly connected to the front of the outer surface of the water outlet pipe 52. A valve 54 is fixedly connected to the water outlet of each of the several connecting pipes 53. A transparent pipe 55 is fixedly connected to the water outlet of each of the several valves 54. The rear end of the several transparent pipes 55 is fixedly connected to the front end of the coloring board 8.

[0042] In the above, when it is necessary to continue the teaching demonstration, the valve 54 installed on the transparent tube 55 to be displayed can be rotated to make the valve 54 an unfolding device. Then, the water in the water tank 51 flows into the corresponding transparent tube 55 through the water outlet pipe 52 and the open valve 54. Under the action of the color plate 8, the transparent tube 55 acts as a bar graph. When the water enters the transparent tube 55 and reaches the required height, the valve 54 can be closed to prevent the water in the water tank 51 from flowing into the transparent tube 55.

[0043] In the above, by controlling several valves 54, water in the water cylinder 51 flows into different transparent tubes 55, thereby making the transparent tubes 55 appear as a bar graph for demonstration and teaching.

[0044] As described above, after the demonstration is completed, the water in the transparent tube 55 can be returned to the water cylinder 51 for the next demonstration and teaching. At this time, the display board 3 needs to be rotated 180 degrees first, and then the valves 54 are opened in sequence. At this time, the water will flow back into the water cylinder 51 through the connecting pipe 53 and the outlet pipe 52 due to gravity. After the water in the transparent tube 55 has completely returned, the valves 54 are closed in sequence, and then the display board 3 is rotated back to its original position.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
