The user cannot actively change the distance between the laser pen and the demonstration lens to explore the effect of the distance variable on the light path. Moreover, students can only observe the single light path phenomenon at a fixed distance and cannot understand the influence of distance on the light path by comparing the light path differences at different distances. Therefore, a physical optical circuit demonstration device is proposed. Summary of the Invention

[0019] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to 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. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0020] Please refer to Figure 1-7 , a physical optical path demonstration device, including a housing 1, a regulator 2, and two lens holders 3. Two slots 4 are opened on the right side of the housing 1, and laser pen bodies 5 are arranged inside both of the two slots 4.

[0021] The laser pen bodies 5 are provided in two, corresponding to the two lens holders 3 respectively. When the lens holders 3 are moved to different positions by starting the motor 202 in the regulator 2, the optical path differences at different distances can be compared to understand the influence of distance on the optical path.

[0022] The regulator 2 includes an installation box 201. The installation box 201 is fixedly installed inside the housing 1. A motor 202 is fixedly installed inside the installation box 201. A gear 203 is fixedly installed at the output shaft of the motor 202. Tooth plates 204 are meshed with both the top and bottom of the gear 203. Connecting plates 205 are fixedly installed at the opposite ends of the two tooth plates 204.

[0023] The installation box 201 is fixedly installed inside the housing 1 and is the installation carrier for other components of the regulator 2. The openings adapted to the connecting plates 205 opened at the top and bottom facilitate the left and right movement of the connecting plates 205 driven by the motor 202. The gear 203 is fixedly connected to the output shaft of the motor 202. When the motor 202 is started, the gear 203 rotates accordingly. Since the top and bottom of the gear 203 are both meshed with the tooth plates 204, when the gear 203 rotates, the tooth plates 204 will perform linear motion along the slide bars 206 on the front inner wall and the rear inner wall of the installation box 201. The slide bars 206 are adapted to the chutes 207 opened on the opposite sides of the tooth plates 204, playing a guiding role to ensure the stability of the tooth plates 204 during movement, avoiding the deviation of the tooth plates 204 during movement, ensuring that the two lens holders 3 can move towards or away from each other smoothly. The connecting plates 205 fixedly installed at the opposite ends of the two tooth plates 204 are used to connect the lens holders 3, transmitting the linear motion of the tooth plates 204 to the lens holders 3, realizing the adjustment of the positions of the lens holders 3, so that the lenses fixed in the two lens holders 3 can move in opposite directions and be in different positions.

[0024] Each of the two lens holders 3 includes a plate body 301. Plate bodies 301 are fixedly installed on the opposite sides of the two connecting plates 205. An installation cavity 302 is formed in the middle of the plate body 301. A fixed annular plate 303 is fixedly installed inside the plate body 301. An active annular plate 304 is rotatably installed inside the fixed annular plate 303. An adjusting rod 305 is slidably installed inside the fixed annular plate 303. A limiting rod 306 is fixedly installed on one side of the adjusting rod 305. An arc-shaped groove 307 adapted to the limiting rod 306 is formed on one side of the active annular plate 304. An adjusting block 308 is fixedly installed at one end of the adjusting rod 305. A limiting component 309 is arranged on one side of the plate body 301.

[0025] The function of the lens holder 3 is to fix different lenses. Place the lens inside the installation cavity 302. Through the rotation of the active annular plate 304 and the sliding cooperation between the limiting rod 306 and the arc-shaped groove 307, the adjusting rod 305 can move inwards or outwards inside the fixed annular plate 303, thereby realizing the fixation of the lens, which facilitates the installation and fixation of different demonstration lenses on the plate body 301.

[0026] The limiting component 309 plays a role in limiting the active annular plate 304, so that the lens is stably fixed in the installation cavity 302. When it is necessary to adjust the angle of the active annular plate 304, pull the pull rod 32 to make the clamping block 33 disengage from the convex block 35. At this time, the active annular plate 304 can rotate freely. After the adjustment is completed, release the pull rod 32. Under the action of the first spring 34, the clamping block 33 re-clamps the convex block 35 to fix the active annular plate 304 at the current angle.

[0027] The installation component 6 plays a role in fixing the laser pen main body 5. The second spring 601 is fixedly installed on the inner top wall of the groove body 4. The pressing plate 602 fixedly installed at its bottom can apply a downward pressure to the laser pen main body 5 placed in the groove body 4 under the elastic force of the second spring 601, ensuring that the laser pen main body 5 is stably fixed in the groove body 4, avoiding the shaking of the laser pen main body 5 during the demonstration process, ensuring the stability of the laser beam. The anti-slip pad 603 increases the friction with the laser pen main body 5, further improving the stability of the laser pen main body 5 in the groove body 4 and preventing the laser pen main body 5 from sliding during placement or demonstration.

[0028] Working principle: When in use, place the lens to be demonstrated into the installation cavity 302 of the plate body 301. First, hold the rod body. The rod body drives the movable annular plate 304 to rotate through the arc-shaped connection port 36. The movable annular plate 304 drives the arc-shaped groove 307 to rotate, so that the limit rod 306 slides in the arc-shaped groove 307, and then drives the adjusting rod 305 to move inward and fix the lens through the adjusting block 308. Then release the pull rod 32 on the bracket 31. The expansion of the first spring 34 drives the block 33 to return to its original position and latch onto the convex block 35 to complete the fixation of the lens. Then start the motor 202. Under the cooperation of the gear 203 and the two toothed plates 204, drive the two lens holders 3 to move and adjust the distance between the two lenses and the corresponding laser pen body 5.

[0029] In summary, for this physical optical circuit demonstration device, two laser pen bodies 5 and the corresponding lens holders 3 are provided. Inside the adjuster 2, the motor 202 drives the gear 203 to rotate. The gear 203 drives the engaged toothed plate 204 to perform a linear motion. The toothed plate 204 is connected to the plate body 301 in the lens holder 3 through the connecting plate 205. In this way, the lenses in the two lens holders 3 can be moved to different positions. Students can clearly see that after the distance between the lenses at different positions and the laser pen body 5 changes, the optical path of the light emitted by the laser pen body 5 passing through the lens is also different. Through this intuitive comparison, students can better understand the influence of distance on the optical path and make the originally abstract physical knowledge easier to master.

[0030] Furthermore, by setting the lens holder 3, various lenses placed in the installation cavity 302 can be fixed. In addition, the limit component 309 can fix the movable annular plate 304 to ensure that the lens is stably placed in the installation cavity 302. This design enables teachers and students to conveniently and quickly install and fix different types of lenses during experiments, meeting the needs of various optical experiment demonstrations.
