[0022] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0023] 1. In the present invention, by pushing the optical bench, convex lens and light screen to one side of the protective shell, then folding the slide rail one and the slide rail two, the surface of the slide rail one will contact the surface of the sealing rod, and the sealing rod will be pushed to contract into the slide rail two, squeezing the air inside the slide rail two.

[0037] 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 of 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.

[0038] As Figures 1 to 10 shown, the present invention provides an experimental device for convex lens imaging, including a first slide rail 1, an optical bench 9, a convex lens 10 and a light screen 11, and further includes:

[0039] A second slide rail 2, which is arranged on one side of the first slide rail 1 and is connected to the first slide rail 1 through a hinge chain;

[0040] A protection mechanism 3 is arranged inside the second slide rail 2;

[0041] Among them, the protection mechanism 3 includes a sealing plate 301 fixedly connected to the top end of the first slide rail 1. One side of the second slide rail 2 is rotatably connected with a protective shell 302. One side of the protective shell 302 is fixedly installed with a connecting shaft 303 located inside the second slide rail 2. A chute 304 is formed on the surface of the connecting shaft 303. A sliding shell 306 is slidably sleeved on the surface of the chute 304. The sliding shell 306 is elastically connected to the second slide rail 2 through a first spring 305. A ball 307 located inside the chute 304 is rotatably connected inside the sliding shell 306.

[0042] With the above solution: When the operator finishes the experiment and needs to carry it, 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 first slide rail 1 and the second slide rail 2 can be folded in the direction of the arrow. During the folding process, the surface of the first slide rail 1 will contact the surface of the sealing rod 308 and push the sealing rod 308 to contract into the second slide rail 2 to squeeze the air inside the second slide rail 2. As the gas is compressed, it will push the sliding shell 306 to move. When the sliding shell 306 moves, the first spring 305 will be stretched. The moving sliding shell 306 will drive the ball 307 to roll inside the chute 304. The ball 307 will roll along the inner wall of the chute 304 and drive the connecting shaft 303 to rotate. The connecting shaft 303 will drive the protective shell 302 to rotate Figure 1 ninety degrees in the direction of the arrow, so that the optical bench 9, the convex lens 10 and the light screen 11 enter the protective shell 302. Through the mutual cooperation between the protective shell 302 and the sealing plate 301, the optical bench 9, the convex lens 10 and the light screen 11 will be protected to avoid damage to the optical bench 9, the convex lens 10 and the light screen 11 during the handling process. Figure 2 As shown in

[0043] such as Figure 1 , Figure 6 and Figure 7 shown, it further includes: a support mechanism 4, which is respectively arranged at one end of the first slide rail 1 and the second slide rail 2;

[0044] The support mechanism 4 includes support seats 402 fixedly connected to one end of the first slide rail 1 and the second slide rail 2. Pressure plates 401 are slidably connected inside the first slide rail 1 and the second slide rail 2. Grooves communicating with the support seats 402 are formed inside the first slide rail 1 and the second slide rail 2. Two mounting rods 404 are slidably connected inside each of the two support seats 402. The two mounting rods 404 and the support seats 402 are elastically connected through second springs 403 respectively. The bottom ends of the two mounting rods 404 are rotatably connected with contact plates 405 located outside the support seats 402.

[0045] Adopting the above scheme: Through the design of the support mechanism 4, when the device needs to be used, the first slide rail 1 and the second slide rail 2 can be unfolded. During the unfolding process, the two pressing plates 401 will come into contact, and through extrusion, they will respectively contract into the interior of the first slide rail 1 and the second slide rail 2. The contracted pressing plates 401 will squeeze the air in the first slide rail 1 and the second slide rail 2, and the squeezed air will enter the interior of the support base 402, and will push the mounting rod 404 and the contact plate 405 downward. The surface of the contact plate 405 will contact the desktop of the lecture desk, increasing the stability of the experiment. When encountering a lecture desk with a display screen, it will cause one end of the lecture desk to be a concave chute for installing the display screen. The descending contact plate 405 will contact the inclined surface and will rotate along the inclined surface in the direction of the arrow, so that the contact plate 405 can fit the entire inclined surface. Furthermore, the mounting rod 404 can enable the contact plate 405 to support the entire device, avoiding the phenomenon of floating at the end of the device close to the inclined surface. After the device is fully unfolded, the candle can be placed on the top of the optical bench 9. Then, the light of the candle will be projected onto the surface of the light screen 11 through the convex lens 10, thereby completing the experimental process. Finally, by unfolding the first slide rail 1 and the second slide rail 2, the contact plate 405 can increase the stability of the experiment, and when there is a lecture desk with an inclined surface groove, the contact plate 405 will rotate to fit the inclined surface, avoiding the phenomenon of floating at the end of the device close to the inclined surface. Figure 5 As shown in FIGS. Figure 5 , ,

[0046] , Figure 6 , Figure 7 , Figure 8 , it further includes: a fixing mechanism 5, which is arranged inside the support base 402;

[0046] As Figure 6 , Figure 7 and Figure 8 shown, it further includes: a fixing mechanism 5, which is arranged inside the support base 402;

[0047] The fixing mechanism 5 includes a slide rod 501 slidably connected inside the support base 402. A contact block 502 is fixedly installed at one end of the slide rod 501 close to the mounting rod 404. A rotating rod 503 is rotatably connected inside the end of the slide rod 501 far from the mounting rod 404. A fixing hole 504 is formed on the surface of the rotating rod 503. Limit blocks 505 fixedly installed inside the two support bases 402 are located inside the fixing hole 504.

[0048] Adopting the above solution: Through the design of the fixing mechanism 5, during the support of the entire device by the mounting rod 404 and the contact plate 405, the rotating rod 503 can be pushed to move inside the support base 402. When the rotating rod 503 moves, the limiting 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, continue to push the rotating rod 503 to squeeze the contact block 502. Since the contact block 502 is made of rubber material, the contact block 502 will deform through extrusion, and thus can tightly fit the surface of the mounting rod 404. Then, the rotating rod 503 can be rotated. Since the fixing hole 504 is designed in an L shape, during the rotation process, the limiting block 505 can limit the rotating rod 503, and then through the friction force between the mounting rod 404 and the contact block 502, the contact block 502 can limit the mounting rod 404, increasing the stability of the support of the contact plate 405 and the mounting rod 404.

[0049] As Figure 2 and Figure 9 shown, it further includes: a connection component 6, which is arranged on one side of the slide rail 1 and the slide rail 2;

[0050] The connection component 6 includes a metal plate 601 and a mounting plate 602 that are respectively fixedly connected to one side of the slide rail 1 and the slide rail 2, and a neodymium magnet 603 is fixedly installed inside the mounting plate 602.

[0051] Adopting the above solution: Through the design of the connection 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 thus the neodymium magnet 603 can be adsorbed on the surface of the metal plate 601, thereby being able to fix the slide rail 1 and the slide rail 2, avoiding the folding phenomenon of the slide rail 1 and the slide rail 2 during the experiment.

[0052] As Figure 3 and Figure 4 shown, the slide rail 2 and the sealing rod 308 are elastically connected by a third spring 7. The number of the third springs 7 is two, and they are symmetrically designed horizontally with respect to the center of the sealing rod 308.

[0053] Adopting the above solution: Through the design of the third spring 7, when the sealing rod 308 retracts into the slide rail 2, the third spring 7 will be stretched. When the slide rail 1 and the slide rail 2 are fully unfolded, the stretched third spring 7 will recover, and will push the sealing rod 308 to reset, and the stretched first spring 305 will reset. Then, the protective shell 302 will rotate in the reverse direction, thus moving away from the optical bench 9, the convex lens 10, and the light screen 11. Then, the operator can conduct experimental tests.

[0054] As Figure 5As shown, the first slide rail 1 and the second slide rail 2 are elastically connected to the extrusion plate 401 through the fourth spring 8, and the opposite sides of the extrusion plate 401 are designed with rounded corners.

[0055] Adopting the above solution: through the design of the fourth spring 8, when the extrusion plate 401 retracts into the first slide rail 1 and the second slide rail 2, the fourth spring 8 will be stretched. When folding the first slide rail 1 and the second slide rail 2, the fourth spring 8 will push the extrusion plate 401 to move, and the mounting rod 404 will move upward, thus facilitating the operator to fold the first slide rail 1 and the second slide rail 2. Moreover, the opposite sides of the extrusion plate 401 are designed with rounded corners, which can reduce the resistance between the two extrusion plates 401 and facilitate the extrusion plate 401 to retract into the first slide rail 1 and the second slide rail 2.

[0056] As Figure 4 、 Figure 6 and Figure 7 shown, the chute 304 is designed to be curved, the surface of the ball 307 is designed to be smooth, and the surface of the ball 307 fully fits the inner wall of the chute 304. The slide rod 501 is designed to be arc-shaped and has a rough surface.

[0057] Adopting the above solution: through the design of the chute 304, since the chute 304 is designed to be curved and the surface of the ball 307 fits the inner wall of the chute 304, when the ball 307 moves, it will move along the curved angle of the chute 304. When moving, it will drive the connecting shaft 303 to rotate. Moreover, the ball 307 is designed to be smooth, which increases the smoothness of its rolling. Through the design of the slide rod 501, since the slide rod 501 is designed to be arc-shaped, it can fully fit the surface of the mounting rod 404. And the mounting rod 404 is designed to be rough, which can increase the friction between the mounting rods 404 and ensure the stability of the fixation of the mounting rod 404.

[0058] As Figure 7 and Figure 8 shown, one end of the rotating rod 503 extends to the outside of the support base 402 and is fixedly installed with a rhombic block. The contact plate 405 is made of rubber material and is symmetrically designed.

[0059] Adopting the above solution: through the design of the rotating rod 503, since a rhombic block is provided on one side of the rotating rod 503, the operator can hold the rhombic block for operation. And the rhombic block is designed to be hexagonal, which facilitates 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, it can protect the tabletop and prevent scratches on the tabletop during the support process.

[0060] The working principle and usage process of the present invention:

[0061] First, when the operator needs to use it, the slide rail 1 and the slide rail 2 need to be unfolded. The two pressing plates 401 will come into contact with each other and will respectively contract into the slide rail 1 and the slide rail 2 to squeeze the air inside the slide rail 1 and the slide rail 2. The squeezed air will push the mounting rod 404 and the contact plate 405 downward, and the contact plate 405 will contact the desktop of the lectern, thereby supporting the device. When encountering a table with a sloped depression, the descending contact plate 405 will rotate along the slope, so that the contact plate 405 fits the entire slope. And the contact plate 405 is made of rubber material, which can protect the desktop. Then the mounting rod 404 and the contact plate 405 can also prevent the phenomenon of floating at one end of the device close to the slope;

[0062] After the support is completed, the diamond block can be pushed to drive the slide bar 501 and the contact block 502 to contact the surface of the mounting rod 404 by the rotating rod 503. After the contact, continue to push the rotating rod 503 to squeeze the contact block 502, so that the contact block 502 will deform and can tightly fit the surface of the mounting rod 404. The rotating rod 503 can be rotated, and the limiting 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 limits the mounting rod 404, increasing the stability of the support of the contact plate 405 and the mounting rod 404. When fully unfolded, the connecting component 6 can fix the slide rail 1 and the slide rail 2. Then the candle can be placed inside the optical bench 9, and then the light of the candle will pass through the convex lens 10 and be projected onto the surface of the light screen 11. Then the operator can record and observe the experimental data;

[0063] 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 folded Figure 1 in the direction of the arrow. 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 slide rail 2 to squeeze the air inside the slide rail 2, and the spring three 7 will be stretched. The squeezed air will push the sliding shell 306 and the ball 307 to move. The ball 307 rolls inside the chute 304. The ball 307 will roll along the inner wall of the chute 304 and will drive the connecting shaft 303 to rotate. The connecting shaft 303 will drive the protective shell 302 to Figure 2 rotate ninety degrees in the direction of the arrow, so that the optical bench 9, the convex lens 10 and the light screen 11 enter the protective shell 302. Through the mutual cooperation between the protective shell 302 and the sealing plate 301, the optical bench 9, the convex lens 10 and the light screen 11 will be protected. Then the operator can carry it, and finally complete the operation process.
