[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0020] like Figures 1 to 10 As shown, the present invention provides a convex lens imaging experimental device, including a slide rail 1, an optical bench 9, a convex lens 10 and a light screen 11, and also includes: Slide rail 2 2 is arranged on one side of slide rail 1 and connected to slide rail 1 through a hinge chain; A protection mechanism 3, which is arranged inside the slide rail 2; Among them, the protection mechanism 3 includes a sealing plate 301 fixedly connected to the top of the slide rail 1, a protection shell 302 is rotatably connected to one side of the slide rail 2, a connecting shaft 303 located inside the slide rail 2 is fixedly installed on one side of the protection shell 302, a slide groove 304 is opened on the surface of the connecting shaft 303, a sliding shell 306 is slidably sleeved on the surface of the slide groove 304, the sliding shell 306 is elastically connected to the slide rail 2 by a spring 305, and the inside of the sliding shell 306 is rollingly connected to a ball 307 located inside the slide groove 304.

[0021] The above solution is adopted: when the experiment is completed and the operator needs to move the optical bench 9, the convex lens 10 and the optical screen 11 to one side of the protective shell 302, the slide rail 1 and the slide rail 2 can be pressed. Figure 1 The sliding housing 306 is folded in the direction of the arrow. During the folding process, the surface of the slide rail 1 will contact the surface of the sealing rod 308, and push the sealing rod 308 to contract into the inside of the slide rail 2 to squeeze the air inside the slide rail 2. As the gas is compressed, the sliding housing 306 is pushed to move. When the sliding housing 306 moves, the spring 1 305 will be stretched, and the moving sliding housing 306 will drive the ball 307 to roll inside the slide groove 304. The ball 307 will roll along the inner wall of the slide groove 304 and drive the connecting shaft 303 to rotate. The connecting shaft 303 will drive the protective housing 302 to move. Figure 2 Rotate ninety degrees in the direction of the arrow so that the optical bench 9, convex lens 10 and light screen 11 enter the interior of the protective shell 302. The protective shell 302 cooperates with the sealing plate 301 to protect the optical bench 9, convex lens 10 and light screen 11, avoiding damage to the optical bench 9, convex lens 10 and light screen 11 during transportation.

[0022] like Figure 1 , Figure 6 and Figure 7 As shown, it also includes: a support mechanism 4, which is respectively arranged at one end of the slide rail 1 and the slide rail 2; The supporting mechanism 4 includes a supporting seat 402 fixedly connected to one end of the slide rail 1 and the slide rail 2, the interior of the slide rail 1 and the slide rail 2 are both slidably connected with an extrusion plate 401, and the interior of the slide rail 1 and the slide rail 2 is provided with a groove connected to the supporting seat 402, the interior of the two supporting seats 402 are both slidably connected with two mounting rods 404, the two mounting rods 404 are elastically connected to the supporting seats 402 by springs 2 403 respectively, and the bottom ends of the two mounting rods 404 are rotatably connected with a contact plate 405 located outside the supporting seat 402.

[0023] The above scheme is adopted: through the design of the supporting mechanism 4, when the device needs to be used, the slide rail 1 and the slide rail 2 2 can be unfolded, and in the process of unfolding, the two extrusion plates 401 will contact each other and will be respectively retracted into the inside of the slide rail 1 1 and the slide rail 2 2 through extrusion, and the retracted extrusion plates 401 will squeeze the air of the slide rail 1 1 and the slide rail 2 2, and the squeezed air will enter the inside of the supporting seat 402, and will push the mounting rod 404 and the contact plate 405 to descend, and the surface of the contact plate 405 will contact the desktop of the desk to increase the stability of the experiment, and when encountering a desk with a display screen, one end of the desk will be a recessed inclined groove for installing the display screen, and the descending contact plate 405 will contact the inclined surface and will press Figure 5In the direction of the arrow, it rotates along the inclined surface, so that the contact plate 405 can fit the entire inclined surface, and then the mounting rod 404 can enable the contact plate 405 to support the entire device, avoiding the floating phenomenon at the end of the device close to the inclined surface. After the device is fully unfolded, a candle can be placed on the top of the light fixture base 9, and then the candle light will be projected onto the surface of the light screen 11 through the convex lens 10, thereby completing the experimental process, and finally by unfolding the slide rail 1 and the slide rail 2 2, the contact plate 405 can increase the stability of the experiment, and when there is a lectern with an inclined groove, the contact plate 405 will rotate to fit the inclined surface, avoiding the floating phenomenon at the end of the device close to the inclined surface.

[0024] like Figure 6 , Figure 7 and Figure 8 As shown, it also includes: a fixing mechanism 5, which is arranged inside the support seat 402; The fixing mechanism 5 includes a sliding rod 501 slidably connected to the inside of the support seat 402, a contact block 502 is fixedly installed on one end of the sliding rod 501 close to the mounting rod 404, and a rotating rod 503 is rotatably connected to the inside of the sliding rod 501 away from the mounting rod 404. A fixing hole 504 is opened on the surface of the rotating rod 503, and a limit block 505 located inside the fixing hole 504 is fixedly installed inside the two support seats 402.

[0025] The above scheme is adopted: through the design of the fixing mechanism 5, in the process of the mounting rod 404 and the contact plate 405 supporting the entire device, the rotating rod 503 can be pushed to move inside the support seat 402. When the rotating rod 503 moves, the limit block 505 will slide inside the fixing hole 504, and then the rotating rod 503 will push the sliding rod 501 and the contact block 502 to contact the surface of the mounting rod 404. After the contact, the rotating rod 503 continues to be pushed to squeeze the contact block 502. Since the contact block 502 is made of rubber material, the contact block 502 will be deformed by squeezing, and then it can be tightly fitted to the surface of the mounting rod 404. Then the rotating rod 503 can be rotated. Since the fixing hole 504 is an L-shaped design, during the rotation process, the limit block 505 can limit the rotating rod 503, and then through the friction between the mounting rod 404 and the contact block 502, the contact block 502 limits the mounting rod 404, thereby increasing the stability of the support of the contact plate 405 and the mounting rod 404.

[0026] like Figure 2 and Fig. 9 As shown, it also includes: a connecting component 6, which is arranged on one side of the slide rail 1 and the slide rail 2; The connecting assembly 6 includes a metal plate 601 and a mounting plate 602 which are respectively fixedly connected to one side of the slide rail 1 and the slide rail 2 2 , and a neodymium magnet 603 is fixedly installed inside the mounting plate 602 .

[0027] The above solution is adopted: through the design of the connecting component 6, after the slide rail 1 and the slide rail 2 are fully unfolded, the neodymium magnet 603 will contact the surface of the metal plate 601, and then the neodymium magnet 603 can be adsorbed on the surface of the metal plate 601, so that the slide rail 1 and the slide rail 2 can be fixed, avoiding the slide rail 1 and the slide rail 2 from folding during the experiment.

[0028] like Figure 3 and Figure 4 As shown, the slide rail 2 and the sealing rod 308 are elastically connected via springs 3 7 . There are two springs 3 7 , and they are designed to be laterally symmetrical about the center of the sealing rod 308 .

[0029] The above scheme is adopted: through the design of spring three 7, when the sealing rod 308 is retracted into the inside of the slide rail two 2, the spring three 7 will be stretched, and when the slide rail one 1 and the slide rail two 2 are fully unfolded, the stretched spring three 7 will recover and push the sealing rod 308 to reset, and the stretched spring one 305 will reset, and then the protective shell 302 will rotate in the opposite direction, thereby moving away from the optical seat 9, the convex lens 10 and the light screen 11, and then the operator can conduct experimental tests.

[0030] like Figure 5 As shown, the slide rail 1 and the slide rail 2 are elastically connected to the extrusion plate 401 via a spring 48, and the opposite side of the extrusion plate 401 is designed with rounded corners.

[0031] The above scheme is adopted: through the design of spring four 8, when the extrusion plate 401 is retracted into the inside of slide rail one 1 and slide rail two 2, the spring four 8 will be stretched, and when slide rail one 1 and slide rail two 2 are folded, the spring four 8 will push the extrusion plate 401 to move, and the mounting rod 404 will move up, so as to facilitate the operator to fold slide rail one 1 and slide rail two 2, and the opposite side of the extrusion plate 401 is designed with rounded corners, thereby reducing the resistance between the two extrusion plates 401 and facilitating the extrusion plate 401 to retract into the inside of slide rail one 1 and slide rail two 2.

[0032] like Figure 4 , Figure 6 and Figure 7 As shown, the slide groove 304 is of curved design, the surface of the ball 307 is of smooth design, and the surface of the ball 307 fully fits the inner wall of the slide groove 304, and the slide rod 501 is of arc design and has a rough surface design.

[0033] The above scheme is adopted: through the design of the slide groove 304, since the slide groove 304 is a curved design, and the surface of the ball 307 fits with the inner wall of the slide groove 304, when the ball 307 moves, it will move along the curved angle of the slide groove 304, and when it moves, it will drive the connecting shaft 303 to rotate, and the ball 307 is smooth in design, thereby increasing the smoothness of its rolling, and through the design of the slide rod 501, since the slide rod 501 is an arc design, it can fully fit with the surface of the mounting rod 404, and the mounting rod 404 is rough in design, which can increase the friction between the mounting rods 404 and ensure the stability of the fixing of the mounting rod 404.

[0034] like Figure 7 and Figure 8 As shown, one end of the rotating rod 503 extends to the outside of the supporting seat 402 and is fixedly mounted with a diamond block. The contact plate 405 is made of rubber material and has a symmetrical design.

[0035] The above scheme is adopted: through the design of the rotating rod 503, since a diamond block is provided on one side of the rotating rod 503, the operator can hold the diamond block for operation, and the diamond block is hexagonal in design, which makes it convenient for the operator to push and rotate the rotating rod 503. Through the design of the contact plate 405, since the contact plate 405 is made of rubber material, the desktop can be protected to avoid scratches on the desktop during the support process.

[0036] The working principle and use process of the present invention: First, when the operator needs to use it, he needs to unfold the slide rail 1 and the slide rail 2, and the two extrusion plates 401 will contact each other, and will shrink to the inside of the slide rail 1 and the slide rail 2 to squeeze the air inside the slide rail 1 and the slide rail 2, and the squeezed air will push the installation rod 404 and the contact plate 405 down, and the contact plate 405 will contact the desktop of the lecture table, so as to support the device, and when encountering a table with a concave inclined surface, the descending contact plate 405 will rotate along the inclined surface, so that the contact plate 405 fits the entire inclined surface, and the contact plate 405 is made of rubber material, which can protect the desktop, and then the installation rod 404 and the contact plate 405 can also prevent the end of the device close to the inclined surface from floating; After the support is completed, the diamond block can be pushed to make the rotating rod 503 drive the sliding rod 501 and the contact block 502 to contact the surface of the mounting rod 404. After the contact, the rotating rod 503 is continued to be pushed to squeeze the contact block 502, so that the contact block 502 will be deformed so that it can fit tightly against the surface of the mounting rod 404. The rotating rod 503 can be rotated, and the limit block 505 can limit the rotating rod 503. Then, through the friction between the mounting rod 404 and the contact block 502, the contact block 502 can limit the mounting rod 404, thereby increasing the stability of the support of the contact plate 405 and the mounting rod 404. When fully unfolded, the connecting assembly 6 can fix the slide rail 1 and the slide rail 2. Then, the candle can be placed inside the light fixture 9, and the candle light will pass through the convex lens 10 and be projected on the surface of the light screen 11. Then the operator can record and observe the experimental data. After the experiment is completed, the optical bench 9, the convex lens 10 and the light screen 11 can be pushed to one side of the protective shell 302. At this time, the slide rail 1 and the slide rail 2 can be pressed Figure 1 The surface of the slide rail 1 will contact the surface of the sealing rod 308, and push the sealing rod 308 to retract into the inside of the slide rail 22 to squeeze the air inside the slide rail 22, and the spring 37 will be stretched, and the squeezed air will push the sliding shell 306 and the ball 307 to move, and the ball 307 will roll inside the slide groove 304, and the ball 307 will roll along the inner wall of the slide groove 304, and will drive the connecting shaft 303 to rotate, and the connecting shaft 303 will drive the protective shell 302 to move. Figure 2 Rotate ninety degrees in the direction of the arrow so that the optical bench 9, convex lens 10 and light screen 11 enter the interior of the protective shell 302. The protective shell 302 cooperates with the sealing plate 301 to protect the optical bench 9, convex lens 10 and light screen 11. Then the operator can move them and finally complete the operation process.
