Abstract
Description
Technical Field
[0001] This utility model relates to the field of microscope technology, and in particular to a rotating lifting structure and a microscope using the same. Background Technology
[0002] The microscope is a core tool for humankind to explore the microscopic world. Since its invention in the 17th century, it has evolved from an early single-lens instrument into a precision device that integrates multiple disciplines, continuously driving breakthroughs in fields such as life sciences and materials science.
[0003] The main types are divided into two categories: one is optical microscopes, which use visible light as a light source and magnify through a combination of lenses. Common bright-field microscopes are suitable for observing high-contrast samples. The other is electron microscopes, which use electron beams instead of visible light and achieve resolution at the atomic level (0.1 nanometers). Among them, transmission electron microscopes (TEM) can observe the internal structure of samples, and scanning electron microscopes (SEM) can generate three-dimensional images of the surface and are mostly used for nanomaterial analysis.
[0004] Handheld microscopes represent an important branch of portable technology. Their small size allows for on-site testing. Equipped with a built-in LED light source and CMOS sensor, they can perform real-time imaging, take photos and videos, and transmit data via USB or WiFi. With a wide range of applications and ease of use, they can be used in teaching settings, freeing microscopic exploration from the limitations of the laboratory and offering greater flexibility.
[0005] When using a microscope, it is generally necessary to have the function of adjusting the position of the internal microscope tube to achieve focal length adjustment. However, the existing structure has significant defects. First, the smoothness of the lifting and adjusting process is insufficient, which is prone to jamming, abnormal noise, and even sudden changes in focal length due to uneven resistance during adjustment, affecting the clarity of observation. Second, the dust protection performance is poor during adjustment. During lifting and rotation, dust in the outside air can easily enter the mechanism through the gaps and may fall onto the surface of the stage or optical lens, contaminating the sample and interfering with the image quality. Frequent disassembly and cleaning are required, increasing maintenance costs and equipment wear and tear.
[0006] Therefore, it is necessary to propose a new technical solution to address the above problems. Utility Model Content
[0007] To overcome the shortcomings mentioned above, this utility model aims to provide a technical solution that can solve the above problems.
[0008] To achieve the above objectives, this utility model provides the following technical solution: a rotating lifting structure, including a lens barrel, a lens barrel fixing component, and a capping cylinder.
[0009] The lens barrel is assembled inside the lens barrel fixing component, allowing it to move vertically. The end of the lens barrel is provided with rotating rods extending to both sides of the lens barrel fixing component. The inside of the capping cylinder is provided with a threaded track, and the rotating rods are embedded in the threaded track.
[0010] As a further embodiment of this utility model: the lens barrel fixing component has a lifting channel inside, and the lens barrel guide is fitted into the lifting channel; The lens barrel fixing component has movable long slots on both sides that are connected to the lifting channel, and the rotating rod passes through the movable long slots and is embedded in the threaded trajectory.
[0011] As a further embodiment of this invention, the width of the movable long groove is the same as the diameter of the rotating rod.
[0012] As a further embodiment of this utility model: the inner wall of the lens barrel is provided with mounting threads.
[0013] As a further embodiment of this utility model: the inner walls of the openings at both ends of the capping cylinder are provided with sleeve grooves.
[0014] This utility model also proposes a microscope, which includes the above-described rotating lifting structure, including a power control component, a transition chamber, and a lens assembly screwed into the inside of the microscope tube. The power control component is provided with a protective shell that connects to the capping cylinder, and the transition chamber is provided with a cover that connects to the capping cylinder.
[0015] As a further embodiment of the present invention: the power control component includes a main control board disposed inside the protective housing, and the main control board is provided with a data interface and a power switch that are exposed through the surface of the protective housing; The protective shell has a first fitting ring at one end, which is connected to the sleeve groove on one side of the capping cylinder.
[0016] As a further embodiment of this utility model: a viewfinder is provided at the front end of the transition chamber, and mounting and fixing shafts extending to both sides of the outside of the transition chamber are provided at both ends of the viewfinder. The front end of the transition chamber is equipped with a sealing cover; The compartment cover has a second fitting ring on one side, which is connected to the sleeve groove on one side of the capping cylinder.
[0017] Compared with the prior art, the beneficial effects of this technical solution are as follows: the microscope tube is assembled into the microscope tube fixing component, and the rotating rods at both ends of the microscope tube extend to the outside. Then, the microscope tube fixing component is installed into the screw cap tube, and the rotating rods are embedded in the threaded track inside the screw cap tube. When the screw cap tube is installed in the microscope, the inside of the microscope tube is used to install the lens assembly. By rotating the screw cap tube, the rotating rods, in cooperation with the threaded track, drive the microscope tube to move up and down, thereby adjusting the focus. The adjustment process is smooth and without jamming. At the same time, during this adjustment process, the microscope tube fixing component always covers the inside of the microscope tube, thereby preventing the entry of external dust and avoiding contamination of the lens assembly and the observed sample.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0022] Please see Figure 1-6 A rotating lifting structure includes a lens barrel 1, a lens barrel fixing component 2, and a capping cylinder 3.
[0023] The lens barrel 1 is assembled inside the lens barrel fixing component 2, which can be raised and lowered. The lens barrel 1 has rotating rods 11 extending to both sides of the lens barrel fixing member 2 at both ends, and the screw cap cylinder 3 has a threaded track 31 inside, with the rotating rods 11 embedded in the threaded track 31.
[0024] Specifically, the microscope tube 1 is assembled into the microscope tube fixing component 2, and the rotating rods 11 at both ends of the microscope tube 1 extend to the outside. Then, the microscope tube fixing component 2 is installed into the screw cap tube 3, and the rotating rods 11 are embedded in the threaded track 31 inside the screw cap tube 3. When the screw cap tube 3 is installed in the microscope, the inside of the microscope tube 1 is used to install the lens assembly 6. By rotating the screw cap tube 3, the rotating rods 11, in cooperation with the threaded track 31, drive the microscope tube 1 to move up and down, thereby adjusting the focus. The adjustment process is smooth and without jamming. At the same time, during this adjustment process, the microscope tube fixing component 2 always covers the inside of the microscope tube 1, thereby preventing the entry of external dust and avoiding contamination of the lens assembly 6 and the observed sample.
[0025] Based on the above embodiments, it is further proposed that the lens barrel fixing component 2 has a lifting channel 21 inside, and the lens barrel 1 is guided and fitted in the lifting channel 21; The lens barrel fixing component 2 has movable long slots 22 on both sides that are connected to the lifting channel 21. The rotating rod 11 passes through the movable long slots 22 and is embedded in the threaded track 31.
[0026] Specifically, the diameter of the microscope tube 1 is the same as the diameter of the lifting channel 21, so that the microscope tube 1 is guided and matched with the lifting channel 21, so that the microscope tube 1 maintains the stability of its axial position during the lifting movement and avoids shaking that would affect the observation of the sample. The movable long slots 22 on both sides of the lens barrel fixing component 2 limit the rotation rod 11, preventing the rotation rod 11 from rotating. Thus, when the capping cylinder 3 is rotated, the rotation rod 11 is restricted by the movable long slots 22, so that as the capping cylinder 3 rotates, the rotation rod 11 drives the lens barrel 1 to move up and down.
[0027] Based on the above embodiments, it is further proposed that the width of the movable long groove 22 is consistent with the diameter of the rotating rod 11; this can restrict the rotating rod 11, reduce the shaking of the rotating rod 11 other than the lifting and lowering movement when the capping cylinder 3 rotates, and thus further improve the smoothness of the lifting and lowering movement of the lens barrel 1.
[0028] Based on the above embodiments, it is further proposed that the inner wall of the lens barrel 1 is provided with mounting threads 12; the mounting threads 12 are used for mounting and fixing the lens assembly 6.
[0029] Based on the above embodiments, it is further proposed that the inner walls of the openings at both ends of the capping cylinder 3 are provided with socket grooves 32, which are used to dock with the protective shell 7 and the compartment cover 8, so that the capping cylinder 3 can be rotatably installed and fixed in the power control component 4 and the transition compartment 5.
[0030] Based on the above-mentioned rotating and lifting structure, this utility model also provides a microscope, which includes a rotating and lifting structure of any one of the above-mentioned claims, and also includes a power control component 4, a transition chamber 5, and a lens assembly 6 screwed into the inside of the microscope tube 1. The power control assembly 4 is provided with a protective shell 7 that docks with the capping cylinder 3, and the transition chamber 5 is provided with a chamber cover 8 that docks with the capping cylinder 3.
[0031] Specifically, the power control component 4 is connected to the capping cylinder 3 via the external protective housing 7, and the transition chamber 5 is connected to the capping cylinder 3 via the chamber cover 8 at one end. The protective housing 7 and the chamber cover 8 are respectively fixedly connected to both ends of the microscope tube fixing component 2. The specific connection method is bolt fastening (not shown in the figure), thereby installing the rotating lifting structure in the microscope and keeping the capping cylinder 3 rotatably installed.
[0032] Preferably, the power control component 4 includes a main control board 41 disposed inside the protective housing 7, and the main control board 41 is provided with a data interface 42, a power switch 43 and a power supply 44 that are exposed through the surface of the protective housing 7. The protective shell 7 has a first fitting ring 71 at one end, which is connected to the sleeve groove 32 on one side of the capping cylinder 3.
[0033] Specifically, the power supply 44 inside the protective casing 7 is used to power the main control board 41, and the data interface 42 is used for data transmission connection; the power control component 4 also includes an image sensor (not shown in the figure) electrically connected to the main control board 41. The image sensor converts the light signal of the image of the lens assembly 6 into an electrical signal and transmits it to the external display device through the data line. The specific principle is common knowledge known to those skilled in the art and will not be elaborated here. The protective housing 7 is connected to the sleeve groove 32 on one side of the capping cylinder 3 via the first fitting ring 71. Then the protective housing 7 is fixed to the lens barrel fixing member 2 by bolts, so that the capping cylinder 3 is rotatably connected to the protective housing 7.
[0034] Preferably, a viewfinder 51 is provided at the front end of the transition chamber 5, and mounting and fixing shafts 52 extending to the outside of the transition chamber 5 are provided at both ends of the viewfinder 51; when observing the sample, the sample can be placed on the sample stage, and then the user can align the viewfinder 51 with the sample, and the mounting and fixing shafts 52 can be fixed on the observation stage (not shown in the figure) to ensure the stability of the microscope during the observation process. The front end of the transition chamber 5 is provided with a sealing cover 53. The sealing cover 53 can seal the front end of the transition chamber 5 when not in use to prevent external dust and impurities from entering. The compartment cover 8 is provided with a second fitting ring 81 on one side, which is connected to the sleeve groove 32 on one side of the capping cylinder 3. The compartment cover 8 is connected to the sleeve groove 32 on one side of the capping cylinder 3 through the second fitting ring 81, and then the second fitting ring 81 is fixed to the lens barrel fixing member 2 by bolts, so that the capping cylinder 3 is rotatably connected to the second fitting ring 81.
[0035] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
