[0002] A lens is an optical element made of a transparent material whose surface is part of a sphere. Optical lenses are made according to the laws of light refraction. An optical lens is a refracting mirror, and its refracting surface is a spherical transparent body.
[0003] However, existing lens support devices have significant limitations in practical applications. When adjusting the height and angle, their adjustment range and accuracy often fail to meet the stringent requirements of complex experiments or special usage scenarios. The adjustment procedures of some devices are cumbersome, requiring the use of special tools or multiple steps for debugging, which greatly affects work efficiency. Furthermore, existing support devices cannot dampen vibrations when fixing lenses, causing even slight vibrations or external interference to cause lens displacement, seriously threatening the reliability of experimental data and application effects. Utility Model Content
[0004] The purpose of this invention is to provide an adjustable optical lens support device to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution:
[0006] An adjustable optical lens support device includes a support base, a support rod on the support base, a height adjustment mechanism between the support rod and the support base, a position rotation mechanism on the height adjustment mechanism, the position rotation mechanism being rotatably connected to the support rod, a mounting frame on the top of the position rotation mechanism, an angle adjustment mechanism on the mounting frame, the angle adjustment mechanism being rotatably connected to the mounting frame, and a support fixing mechanism for fixing the lens on the angle adjustment mechanism.
[0007] In a further technical solution, the height adjustment mechanism includes a height adjustment rod and a pin rod. The support rod is provided with a insertion hole, and the height adjustment rod is provided with a plurality of equally spaced insertion holes. The height adjustment rod is inserted into the support rod, and the pin rod is inserted into the corresponding insertion hole through the insertion hole.
[0008] A further technical solution is provided, wherein the position rotation mechanism includes a rotating gear disk, a top disk, a bottom disk, a spring, a rotating cylinder, and a rotating shaft. The height adjustment rod has a circular mounting cavity inside. The rotating gear disk is located at the top of the circular mounting cavity. The spring is located between the top disk and the bottom disk. The rotating shaft is connected to the bottom of the rotating cylinder. The top disk is connected to the rotating shaft. The top of the top disk has two locking blocks. The bottom disk has a ring that is rotatably connected to the bottom of the circular mounting cavity.
[0009] In a further technical solution, handles are provided on both side walls of the mounting frame.
[0010] In a further technical solution, the angle adjustment mechanism includes a rotating frame, two screws, and two wing nuts. The rotating frame is rotatably connected to the mounting frame. Arc grooves are provided on both side walls of the mounting frame. The two screws are symmetrically arranged on the rotating frame, and the screws extend outward through the arc grooves. The wing nuts are threadedly connected to the screws.
[0011] In a further technical solution, the supporting and fixing mechanism includes two fixing components, the bottom of the rotating frame is an arc-shaped structure, the arc-shaped structure is provided with a protective pad, and the rotating frame is provided with two sliding grooves;
[0012] The two fixing components are slidably connected in two slide grooves respectively. Each fixing component includes a sliding block, an adjusting screw, a fixing screw, a fixing arc plate, and a sliding rod. The fixing screw is vertically rotatably connected in the slide groove, and the top of the fixing screw extends to the top of the rotating frame. The sliding block is slidably connected in the slide groove and threadedly connected to the fixing screw. The adjusting screw is horizontally threadedly connected to the sliding block.

The adjusting screw is provided with a turntable, and the fixing arc plate is provided with a rubber pad.
[0013] The beneficial effects of this utility model are:
[0014] Firstly, when adjusting the position of the lens by rotation, pressing down on the handle causes the rotating shaft to move downward within the height adjustment rod. This causes the top disc to compress the spring, which in turn compresses the bottom disc. The downward movement of the top disc disengages the two locking blocks from the bottom of the rotating gear. Then, rotating the two handles causes the rotating shaft to rotate on the height adjustment rod. At this time, the bottom disc rotates at the bottom of the circular mounting cavity via the ring. After the position adjustment is complete, releasing the two handles allows the rotating shaft to move upward on the height adjustment rod, engaging the two locking blocks within the rotating gear, thus fixing the top disc on the rotating gear and fixing the lens position. Rotating the lens allows for flexible changes to the light propagation path and adjustments to the imaging direction and position.
[0015] Secondly, when adjusting the height of the lens during experiments, this invention allows for adjustment by pulling out the pin and moving the height adjustment rod up or down within the support rod. Once the height is determined, the pin can be inserted into the insertion hole to fix the height adjustment rod within the support rod. By adjusting the lens height, the focal point and parallelism of the light can be precisely controlled, ensuring the light propagates according to the experimental design requirements and yielding accurate experimental results. For example, in a convex lens imaging experiment, adjusting the lens height allows the image to be clearly projected onto a specific position on the screen, facilitating the measurement of image distance and object distance, and the study of imaging principles.

[0023] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.
[0024] Please refer to Figure 1-5 As shown; this utility model provides a technical solution for an adjustable optical lens support device: an adjustable optical lens support device includes a support base 1, a support rod 11 on the support base 1, a height adjustment mechanism 2 between the support rod 11 and the support base 1, a position rotation mechanism 3 on the height adjustment mechanism 2, the position rotation mechanism 3 being rotatably connected to the support rod 11, a mounting frame 4 on the top of the position rotation mechanism 3, an angle adjustment mechanism 5 on the mounting frame 4, the angle adjustment mechanism 5 being rotatably connected to the mounting frame 4, and a support fixing mechanism 6 for fixing the lens on the angle adjustment mechanism 5.
[0025] In this embodiment, refer to Figure 3 As shown, the height adjustment mechanism 2 includes a height adjustment rod 21 and a pin rod 22. The support rod 11 is provided with a insertion hole 23, and the height adjustment rod 21 is provided with a plurality of equally spaced insertion holes 24. The height adjustment rod 21 is inserted into the support rod 11, and the pin rod 22 is inserted into the corresponding insertion hole 24 through the insertion hole 23.
[0026] During the experiment, when adjusting the height of the lens, the pin 22 is pulled outward, and the height adjustment rod 21 is moved up or down within the support rod 11 to adjust the lens height. Once the height is determined, the pin 22 can be inserted into the insertion holes 24 and 23, thus fixing the height adjustment rod 21 within the support rod 11. By adjusting the lens height, the focal point and parallelism of the light can be precisely controlled, ensuring that the light propagates according to the experimental design requirements, thereby obtaining accurate experimental results. For example, in a convex lens imaging experiment, adjusting the lens height allows the image to be clearly projected at a specific position on the screen, facilitating the measurement of image distance and object distance, and the study of imaging laws.
[0027] In this embodiment, refer to Figure 4 As shown, the position rotation mechanism 3 includes a rotating gear 31, a top disc 32, a bottom disc 33, a spring 34, a rotating cylinder 35, and a rotating shaft 36. The height adjustment rod 21 has a circular mounting cavity 25 inside. The rotating gear 31 is located at the top of the circular mounting cavity 25. The spring 34 is located between the top disc 32 and the bottom disc 33. The rotating shaft 36 is connected to the bottom of the rotating cylinder 35. The top disc 32 is connected to the rotating shaft 36. The top of the top disc 32 has two locking blocks 37. The bottom disc 33 has a ring 38 that is rotatably connected to the bottom of the circular mounting cavity 25. Handles 41 are provided on both side walls of the mounting frame 4.
[0028] When adjusting the position of the lens by rotating it, pressing down on the handle 41 will cause the rotating shaft 36 to move downward within the height adjustment rod 21, thereby causing the top disc 32 to compress the spring 34, which in turn compresses the bottom disc 33. The downward movement of the top disc 32 will cause the two locking blocks 37 to disengage from the bottom of the rotating gear disc 31. Then, by rotating the two handles 41, the rotating shaft 36 will rotate on the height adjustment rod 21. At this time, the bottom disc 33 will rotate at the bottom of the circular mounting cavity 25 via the ring 38. After the position adjustment is completed, the two handles 41 can be released, causing the position of the rotating shaft 36 to move upward on the height adjustment rod 21, so that the positions of the two locking blocks 37 are engaged within the rotating gear disc 31, thereby fixing the position of the top disc 32 on the rotating gear disc 31 and thus fixing the position of the lens.
[0029] By rotating a lens, light can be incident and emitted at different angles, thus creating diverse optical paths in an optical system. For example, in experiments that require guiding light to a specific location or precisely coordinating it with other optical components, a rotating lens can flexibly change the direction of the light, achieving complex optical path layouts.
[0030] In imaging experiments, rotating lenses can change the orientation and position of an image. For example, in imaging systems such as microscopes or telescopes, it is sometimes necessary to rotate the image of an object to a specific angle for observation or measurement; this can be easily achieved by rotating lenses. Furthermore, for experiments requiring precise positioning of the image in a specific area, rotating lenses can also fine-tune the image's position.
[0031] In this embodiment, refer to Figure 5As shown, the angle adjustment mechanism 5 includes a rotating frame 51, two screws 52 and two wing nuts 53. The rotating frame 51 is rotatably connected to the mounting frame 4. Arc grooves 42 are provided on both side walls of the mounting frame 4. The two screws 52 are symmetrically arranged on the rotating frame 51 and extend outward through the arc grooves 42. The wing nuts 53 are threadedly connected to the screws 52.
[0032] During the experiment, when adjusting the lens angle, the two wing nuts 53 are rotated to loosen the rotating frame 51, allowing it to rotate within the two arc-shaped grooves 42 via the two screws 52. After adjusting the lens to the appropriate position, the two wing nuts 53 are rotated to fix the rotating frame 51 onto the mounting frame 4. During the experiment, the lens angle can be adjusted, precisely changing the refraction path of light to propagate in the expected direction. For example, in optical imaging experiments, accurately adjusting the lens angle allows light to be focused precisely at a specific position on the imaging plane, forming a clear and accurate image, which is helpful in studying imaging laws and characteristics.
[0033] In this embodiment, refer to Figure 5 As shown, the supporting and fixing mechanism 6 includes two fixing members 60. The bottom of the rotating frame 51 has an arc-shaped structure, and a protective pad 67 is provided on the arc-shaped structure. The rotating frame 51 has two sliding grooves 43. The two fixing members 60 are slidably connected in the two sliding grooves 43 respectively. Each fixing member 60 includes a sliding block 61, an adjusting screw 62, a fixing screw 63, a fixing arc plate 64, and a sliding rod 65. The fixing screw 63 is vertically rotatably connected in the sliding groove 43 and is fixed. The top of the fixed screw 63 extends above the rotating frame 51. The sliding block 61 is slidably connected within the sliding groove 43 and threadedly connected to the fixed screw 63. The adjusting screw 62 is horizontally threadedly connected to the sliding block 61. The fixed arc plate 64 is rotatably connected to the fixed screw 63. The sliding rod 65 is slidably connected to the sliding block 61 and connected to the fixed arc plate 64. The adjusting screw 62 is equipped with a turntable 66, and the fixed arc plate 64 is equipped with a rubber pad. The rubber pad protects the lens.
[0034] When fixing the lens, after placing the lens on the protective pad 67, the height of the fixing arc plate 64 can be adjusted according to the different lens sizes. At this time, the fixing screw 63 can be rotated to drive the sliding block 61 to move up and down in the slide groove 43, thereby adjusting the position of the fixing arc plate 64 to a position that matches the height of the lens. This allows the fixing arc plate 64 to be adjusted according to the different lens sizes when fixing the lens, so as to better fit and fix the lens.
[0035] Rotating the turntable 66 will cause the adjusting screw 62 to rotate on the sliding block 61, thereby causing the fixed arc plate 64 to move horizontally on the sliding block 61 via the sliding rod 65. This moves the position of the arc plate to the side of the lens, fixing the position of the lens and preventing it from shifting during experiments or use, which would affect the accuracy of the experiment.
