[0002] An optical lens is an optical element made of a transparent material whose surface is part of a sphere. Optical lenses of different sizes are usually used in physical candle lens imaging experiments.
[0003] Publication number CN214771480U discloses a clamping device applicable to optical lenses of different sizes. This clamping device not only increases the anti-tipping function of the base, but also reduces the probability of tipping or displacement due to external force during use. The device achieves clamping operation through two sets of V-shaped clamping plates and electric push rods. However, it is not convenient to move the entire device after it is installed, so it is impossible to perform simple fine-tuning operations on the device during the experiment, which may affect the final experimental results. Utility Model Content

[0010] Preferably, the support rod has multiple sets of adjustment holes, and the knob matches the adjustment holes;
[0011] This allows experimenters to easily adjust the extension length of the support rod, thereby adjusting the overall height of the device.

[0015] Used to guide the slider, thereby enabling it to move linearly along a set trajectory.
[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0027] Reference Figure 1-5This utility model provides an embodiment of a clamping device for holding optical lenses of different sizes, including a support assembly 1 and a clamping assembly 2 installed on the upper end of the support assembly 1. The support assembly 1 includes a base 11, with a fixing pin 12 provided on the upper end of the base 11. The outer surface of the fixing pin 12 is also provided with multiple sets of protrusions to increase the friction between the hand and the fixing pin 12, thereby facilitating the removal of the fixing pin 12. A clamping member 13 is slidably connected inside the base 11. An elastic pad is also installed on the inner surface of the clamping member 13. The elastic pad increases the clamping range of the clamping member 13 by compression deformation, and also provides simple protection for the experimental table to prevent scratches. The fixing pin 12 fixes the clamping member 13. A sleeve 14 is fixedly connected to the upper surface of the base 11. A knob 15 is installed on the upper end of the sleeve 14. A support rod 16 is slidably connected inside the sleeve 14. The knob 15 limits the support rod 16. The height of the support frame 21 can be adjusted according to the experimental needs to ensure the normal operation of the experiment.
[0028] The clamping assembly 2 includes a support frame 21, which is fixedly installed on the top of the support rod 16. The support frame 21 has a mounting groove 22, in which a lead screw 23 is rotatably installed, driving the slider 24 to move, thereby adjusting the position of the clamped optical lens. One end of the lead screw 23 passes through the support frame 21 and extends to its outer side. The outer surface of the lead screw 23 is threadedly connected to the slider 24. The upper surface of the slider 24 is fixedly connected to a clamping frame 25, and the clamping frame 25 is threadedly connected to a clamping post 26, which works with the clamping frame 25 to clamp optical lenses of different thicknesses.
[0029] An anti-slip pad 111 is fixedly connected to the bottom surface of the base 11. The anti-slip pad 111 is made of elastic material, which increases the friction between the base 11 and the experimental table while preventing the base 11 from directly contacting the experimental table and thus avoiding damage to the surface of the experimental table. The clamping member 13 has multiple sets of through holes 131, and the fixing pin 12 matches the through holes 131 to lock the clamping member 13, thus facilitating the installation of the entire device on experimental tables of different sizes. The support rod 16 has multiple sets of adjustment holes 161, and the knob 15 matches the adjustment holes 161 to facilitate the adjustment of the overall height of the entire device, thereby adapting to different heights. In the optical lens experiment, a limiting hole 211 is provided on the support frame 21. One end of the lead screw 23 is fixedly connected to a turntable 231. A pin 232 is provided on the turntable 231. One end of the pin 232 passes through the turntable 231 and is inserted into the limiting hole 211 to lock the lead screw 23 and prevent it from rotating during the experiment, thus affecting the final experimental results. A guide rod 212 is provided inside the support frame 21. There are two sets of guide rods 212. The lead screw 23 is located between the two sets of guide rods 212. The slider 24 is slidably mounted on the guide rod 212 to guide the slider 24 and make it move according to the set motion trajectory.
[0030] Working principle: First, pull out the fixing pin 12 and then pull out the clamping part 13. The experimental table is clamped by the two sets of clamping parts 13. Then, it is fixed by the fixing pin 12, so that the whole device is installed on the experimental table to prevent it from accidentally tipping over during the experiment. Then, turn the knob 15 to adjust the extension length of the support rod 16, so that the whole device is adjusted to a suitable experimental height. After everything is ready, install the optical adjustment on the clamping frame 25. Then, turn the clamping column 26 to clamp the optical lens. The contact surfaces between the clamping frame 25 and the clamping column 26 and the optical lens are all equipped with pads to protect the optical lens. Then, remove the pin 232 and turn the lead screw 23 to adjust the slider 24 to make it horizontally displaced, so that the optical lens is adjusted to a suitable position and can work normally to ensure the normal conduct of the experiment.
[0031] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
