[0029] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0030] Please refer to Figures 1 - 7 , the present invention provides a technical solution: a teaching demonstration device for financial risk management, including a teaching demonstration board 1, a support column 2 is installed at the bottom end of the teaching demonstration board 1, and a placing base 201 is fixedly installed at the bottom end of the support column 2. A first fixing block 202 is inserted into the support column 2, and a first resisting spring 203 is installed inside the support column 2;

[0031] A second fixing block 204 is inserted into the support column 2, a second resisting spring 205 is installed inside the support column 2, a limiting pressure plate 206 is installed on the surface of the support column 2, an extension plate 3 is installed on the surface of the placing base 201, and a mounting rod 301 is fixedly installed inside the placing base 201.

[0032] Through the above technical solution, after the placing base 201 and the extension plate 3 are placed horizontally, the extension plate 3 is pressed by the limiting pressure plate 206 for limiting. In this way, after the placing base 201 and the extension plate 3 are placed horizontally on the ground, the overall size of the base can be extended, thereby increasing the overall contact area between the base and the ground.

[0033] On the right side of the front of the teaching demonstration board 1 in this example, a smoothing component 4 is installed. On the right side of the front of the teaching demonstration board 1, a clamping component 5 is fixedly installed. Inside the teaching demonstration board 1, a limiting frame 6 is installed. On the left side of the front of the teaching demonstration board 1, a cleaning component 7 is installed. At the top of the teaching demonstration board 1, a driving motor 8 is installed.

[0034] On the left side of the front of the teaching demonstration board 1, a display screen 101 is installed. At the bottom of the teaching demonstration board 1, two groups of connecting frames 102 are provided. The bottom ends of the connecting frames 102 are fixedly connected to the top ends of the support columns 2.

[0035] Through the above technical solution, the teaching demonstration board 1 and the support column 2 can be fixedly connected through the connecting frame 102, so that the teaching demonstration board 1 can be supported for use.

[0036] The first fixing block 202 and the second fixing block 204 are both inserted through the surface of the support column 2. Circular clamping grooves adapted to the sizes of the first fixing block 202 and the second fixing block 204 are formed on the surface of the limiting pressure plate 206. A limiting groove adapted to the size of the extension plate 3 is formed on the surface of the placing base 201. The extension plate 3 is hingedly installed on the surface of the placing base 201 through the mounting rod 301.

[0037] Through the above technical solution, the position of the limiting pressure plate 206 can be fixed by the clamping of the first fixing block 202 and the second fixing block 204. When the extension plate 3 is installed on the surface of the placing base 201 by a hinged manner, the extension plate 3 can rotate around the mounting rod 301 as the center. In this way, the placing base 201 and the extension plate 3 can be placed horizontally, so that the overall size of the base is extended.

[0038] Sliding frames 401 are fixedly installed at both ends of the smoothing component 4. A pull rod 402 is inserted inside the smoothing component 4, and a return spring 403 is installed on the surface of the pull rod 402. One end of the pull rod 402 is fixedly installed with a smoothing scraper 404. An adjusting knob 501 is inserted inside the clamping component 5, and a fixed clamping block 502 is installed at one end of the adjusting knob 501.

[0039] Two groups of limiting sliding grooves are formed on the front of the teaching demonstration board 1. The sliding frames 401 are inserted into the limiting sliding grooves formed on the front of the teaching demonstration board 1. The pull rod 402 is inserted through the inside of the smoothing component 4, and the pull rod 402 can slide inside the smoothing component 4. The back surface of the smoothing scraper 404 can be attached to the front of the teaching demonstration board 1 by the push of the return spring 403.

[0040] Through the above technical solution, the top of the example graphic can be clamped and fixed by the fixing clamp block 502. After pulling the pull rod 402 and then releasing it, the smoothing squeegee 404 is made to fit on the surface of the graphic. Sliding the smoothing assembly 4 downward can move the smoothing squeegee 404 downward, so that the surface of the graphic can be smoothed by the smoothing squeegee 404, thus keeping the graphic flat and not affecting the viewing of the trainees.

[0041] A transmission screw rod 601 is installed inside the limit frame 6, a driving gear 602 is fixedly installed on the surface of the limit frame 6, a lifting slider 603 is installed on the surface of the transmission screw rod 601, and a connecting slider 604 is fixedly installed on the front surface of the lifting slider 603. A lifting support platform 605 is fixedly installed on the front surface of the connecting slider 604. The cleaning assembly 7 is installed at the top of the lifting support platform 605, and a cleaning agent adding port 701 is installed at the top of the cleaning assembly 7. A cleaning agent delivery pipe 702 is installed at the bottom of the cleaning assembly 7, and a cleaning sponge 703 is installed at one end of the cleaning agent delivery pipe 702.

[0042] The bottom end of the transmission screw rod 601 is installed inside the bottom end of the limit frame 6 through a bearing seat. A screw hole adapted to the size of the transmission screw rod 601 is provided inside the lifting slider 603. The cleaning agent delivery pipe 702 is inserted through the inside of the lifting support platform 605. The back surface of the cleaning sponge 703 is attached to the front surface of the display screen 101.

[0043] An output gear 801 is fixedly installed on the output shaft of the driving motor 8. A transmission rod 802 is installed at the top of the teaching demonstration board 1, and a first transmission gear 803 is fixedly installed on the surface of the transmission rod 802. Second transmission gears 804 are fixedly installed at both ends of the transmission rod 802. A protective shell is provided on the surface of the driving motor 8. The surfaces of the output gear 801 and the first transmission gear 803 are meshed with each other, and the surfaces of the driving gear 602 and the second transmission gear 804 are meshed with each other.

[0044] Through the above technical solution, when the driving motor 8 rotates, it can drive the two groups of transmission screw rods 601 to rotate together. In this way, the rotation of the transmission screw rod 601 can make the lifting slider 603 slide on its surface, and the sliding of the lifting slider 603 can make the lifting support platform 605 lift and lower. When the lifting support platform 605 descends, the cleaning assembly 7 will descend, and at the same time, the cleaning sponge 703 will slide down while being attached to the surface of the display screen 101. As the cleaning sponge 703 slides down, a small amount of cleaning agent can be squeezed out, and the surface of the display screen 101 can be automatically cleaned as the cleaning sponge 703 slides down.

[0045] Working principle: According to Figures 1 - 7As shown in the figure, first, press the first fixing block 202 to move the limit pressing plate 206 upward. When the limit pressing plate 206 no longer blocks the extension plate 3, the extension plate 3 can be rotated around the mounting rod 301, so that the placing base 201 and the extension plate 3 can be placed horizontally. After the extension plate 3 is placed on the ground, press the limit pressing plate 206 downward. The bottom end of the limit pressing plate 206 can press the top end of the extension plate 3, and the limit pressing plate 206 can be limited by the clamping of the second fixing block 204. By placing the placing base 201 and the extension plate 3 horizontally, the overall size of the base can be extended by using the extension plate 3. In this way, when the device is placed and used, the stability of the device during placement and use can be effectively improved by increasing the overall area of the base. And after the device is used, the extension plate 3 can be retracted, and the base of the device can be reduced for storage;

[0046] According to Figures 1 - 7 As shown in the figure, place the example picture and text to be hung on the right side of the front of the teaching demonstration board 1. Rotate the adjustment knob 501 to move the fixing clamp 502, and use the fixing clamp 502 to clamp the top end of the picture and text. Then pull the pull rod 402 to make the picture and text pass through between the teaching demonstration board 1 and the smoothing scraper 404. After releasing the smoothing scraper 404, the back surface of the smoothing scraper 404 can be attached to the surface of the picture and text by the resistance of the return spring 403. Then pull the smoothing component 4 downward. As the smoothing component 4 is pulled downward, the smoothing scraper 404 can move downward while being attached to the surface of the picture and text. Since the smoothing scraper 404 is attached to the surface of the picture and text under the elastic force of the return spring 403, the wrinkles on the surface of the picture and text can be scraped flat as the smoothing scraper 404 moves downward, so that the surface of the hung picture and text remains flat, and thus the students' viewing of the picture and text will not be affected by the wrinkles;

[0047] According to Figures 1 - 7As shown, when dust adheres to the surface of the display screen 101 and affects clarity, the rotation of the drive motor 8 can cause the output gear 801 to rotate. As the output gear 801 rotates, the first transmission gear 803 can be rotated. When the first transmission gear 803 rotates, it drives the transmission rod 802 to rotate, and at the same time, the second transmission gear 804 can be rotated. In this way, the rotation of the second transmission gear 804 can drive the drive gear 602 to rotate, so that the two transmission screws 601 can rotate together. When the transmission screws 601 rotate, the lifting slider 603 slides on its surface, and the lifting platform 605 can be slid downward in this way. When the lifting platform 605 slides downward, the cleaning assembly 7 will also move downward accordingly, and the cleaning sponge 703 will slide downward while adhering to the surface of the display screen 101. Since the back of the cleaning sponge 703 adheres to the surface of the display screen 101, a small amount of cleaning agent can be squeezed out when the cleaning sponge 703 slides downward. As the cleaning sponge 703 slides downward, it can cooperate with the cleaning agent to automatically clean the surface of the display screen 101, so that the surface of the display screen 101 is clearly displayed.

[0048] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
