[0014] Compared with the prior art, the utility model provides an optical lens for a microscope, which has the following

[0015] Beneficial effects:

[0016] 1. The lens replacement becomes more convenient and quick by setting components such as the lens block, the plug rod, the lens slot, and the through hole. The lens can be firmly fixed in place after replacement by setting the clamping cover, the spring, and the clamping groove, without shaking or falling off. This can effectively improve the stability and safety of the lens. The lens frame is made of hard rubber, which can effectively protect the periphery of the lens and avoid damage during the replacement process. This protective measure can extend the service life of the lens and reduce maintenance costs. The upper clamping groove, the lower clamping groove, the L clamping block, and the L clamping groove make the clamping cover have a certain friction when fixed on the lens, and it is not easy to detach, thereby ensuring the firmness of the lens fixation. The entire lens replacement process is simple and clear through the setting of components such as the rotating block and the L clamping block, thereby improving the operating efficiency of lens replacement. The setting of this structure allows users to complete the replacement of the lens by simply following certain steps without complicated tools or professional skills, which is more convenient and quick. At the same time, it also improves the stability and protection of the lens, providing users with a better use experience and the function of protecting the lens.

[0017] 2. The spring can effectively fix the lens block connected to the plug rod by lifting the sliding piece, ensuring that the lens will not loosen or fall off during use. This design ensures the stability of the lens and improves the safety of use. The sliding piece slides in the sliding groove through the slider, ensuring that the sliding piece can maintain smooth movement without tilting or getting stuck during the compression or rebound of the spring. The sliding groove limits the height of the slider and the sliding piece to prevent the sliding piece from detaching from the plug rod when the spring rebounds, ensuring the stability and reliability of the entire structure. The setting of this structure not only ensures the fixing stability and smooth movement of the lens, but also enhances the safety and reliability of the structure through the height limitation function.

DETAILED DESCRIPTION

[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] The utility model provides Figure 1-6 An optical lens for a microscope shown includes a lens 4 and a connecting end 1 arranged at the bottom of the lens 4;

[0027] A plurality of threads 2 are arranged on the outer side of the connection end 1, an adjusting knob 3 is arranged on the lens 4, and a lens 6 is arranged inside the lens 4;

[0028] A clamping cover 7 is provided on the lens 4, a pair of rotating blocks 5 are provided on the outer side of the clamping cover 7, a pair of L clamping blocks 12 are provided at the bottom of the clamping cover 7, an upper clamping groove 13 is provided at the bottom of the clamping cover 7, a lens frame 11 is provided on the outer side of the lens 6, lens clamping blocks 10 are respectively provided on both sides of the lens frame 11, and a through hole 9 is provided on the lens clamping block 10, a lower clamping groove 8 is provided on the lens 4, a pair of L clamping grooves 14 are provided on the lower clamping groove 8, lens clamping grooves 15 are respectively provided on both sides of the lower clamping groove 8, an insertion rod 16 is provided inside the lens clamping groove 15, and a spring 18 is provided on the insertion rod 16.

[0029] In this embodiment, the optical lens for the microscope mainly includes two parts: an objective lens and an eyepiece. The objective lens is a lens 6 placed under the microscope, which is mainly responsible for magnifying the details of the observed object. The focal length of the objective lens is short, so that the light converges to a focus after passing through the objective lens to form an enlarged real image. The eyepiece is a lens placed above the microscope, which is mainly responsible for further magnifying the real image produced by the objective lens. The focal length of the eyepiece is long, so that the observer can see a larger virtual image. Through the synergistic effect of the objective lens and the eyepiece, the microscope can magnify the details of the observed object, so that people can observe tiny structures that are invisible to the naked eye. The method of using the optical lens for the microscope is as follows: first, the lens 4 is fixedly installed on the microscope through the connector 1 and the thread 2, and then the object on the microscope stage can be observed in conjunction with the eyepiece above, and the focal length of the lens 6 can be adjusted by rotating the adjustment knob 3 during observation, thereby obtaining a clearer image for better observation.

[0030] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the rotating block 5 is integrally connected with the clamping cover 7, the L clamping block 12 is integrally connected with the clamping cover 7, the side of the L clamping block 12 is L-shaped, the L clamping block 12 can be clamped with the L clamping groove 14, the upper clamping groove 13 can be clamped with the lens frame 11, the lens frame 11 is made of a harder rubber material, the lens frame 11 is fixedly connected with the lens 6, the lens clamping block 10 is integrally connected with the lens frame 11, the insertion rod 16 is fixedly connected with the lens 4, the lens clamping block 10 can be clamped with the lens clamping groove 15, the insertion rod 16 can be plugged with the through hole 9, and the lower clamping groove 8 can be clamped with the lens frame 11.

[0031] Preferably, through the arrangement of the lens block 10, the insertion rod 16, the lens slot 15, the through hole 9 and the lens frame 11, the lens 6 can be clamped with the lens slot 15 through the lens blocks 10 on both sides, and the insertion rod 16 is inserted into the through hole 9, and the lens frame 11 can be preliminarily fixed through the insertion rod 16. Through the arrangement of the clamping cover 7, the spring 18, the upper clamping groove 13, the lower clamping groove 8, the rotating block 5, the L clamping block 12 and the L clamping groove 14, the clamping cover 7 is placed above the lens frame 11, and the L clamping block 12 is aligned with the L clamping groove 14, and then the clamping cover 7 is pressed downward, and the clamping cover 7 can push the lens frame 11 downward through the upper clamping groove 13 and compress the spring 18. When the L clamping block 12 is completely pushed to the bottom of the L clamping groove 14, the rotating block 5 is rotated. The rotating block 5 can drive the clamping cover 7 and the L clamping block 12 at the bottom to rotate. The rotation of the L clamping block 12 inside the L clamping groove 14 can make the L clamping block 12 clamped at the bottom of the L clamping groove 14, thereby fixing the clamping cover 7 on the lens 4. At this time, the upper clamping groove 13 and the lower clamping groove 8 clamp the lens outer frame 11. At the same time, the spring 18 will support the lens clamping blocks 10 on both sides to stabilize the lens 6. The raised lens outer frames 11 will also push up the clamping cover 7, increasing the friction between the L clamping block 12 at the bottom of the clamping cover 7 and the L clamping groove 14, so that the clamping cover 7 will not easily fall off the lens 4. The arrangement of this structure makes the replacement of the lens 6 more convenient and quick. At the same time, since the lens outer frame 11 is made of hard rubber material, the periphery of the lens 6 can be protected to prevent the lens 6 from being damaged during replacement.

[0032] like Figure 5 and Figure 6 As shown, a sliding sheet 17 is provided on the insertion rod 16, and the sliding sheet 17 is sleeved with the insertion rod 16. Four sliding blocks 20 are provided on the inner side of the sliding sheet 17, and the sliding blocks 20 are integrally connected with the sliding sheet 17. Four sliding grooves 19 are provided on the outer side of the insertion rod 16, and the sliding blocks 20 can be engaged with the sliding grooves 19. The spring 18 is sleeved with the insertion rod 16, and the spring 18 is provided at the bottom of the sliding sheet 17. The connecting end 1 is integrally connected with the lens 4, and the adjusting knob 3 is movably connected with the lens 4, and the adjusting knob 3 can rotate on the lens 4.

[0033] Preferably, through the arrangement of the slide groove 19, the slider 20 and the sliding sheet 17, the spring 18 can fix the lens block 10 connected to the insertion rod 16 by pushing up the sliding sheet 17, and the sliding sheet 17 can slide in the slide groove 19 through the slider 20, so that the sliding sheet 17 will not tilt or get stuck during the compression or rebound of the spring 18, thereby ensuring the stability of the sliding sheet 17. At the same time, the slide groove 19 can limit the height of the slider 20 and the sliding sheet 17 to prevent the spring 18 from rebounding and causing the sliding sheet 17 to disengage from the insertion rod 16.

[0034] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
