Description

Technical Field

[0001] This utility model relates to the field of optical analysis instruments, specifically a rotatable optical microscope solid sample holder. Background Technology

[0002] An optical microscope is an essential tool for observing and studying the microscopic world. It utilizes optical principles and lens systems to magnify samples at the microscopic scale, enabling us to observe the structure and features of cells, tissues, and other tiny objects. With continuous technological advancements, optical microscopes have continuously improved their resolution, magnification, and imaging speed, bringing significant progress to research in various fields. Optical microscopes have broad application prospects in biomedicine, materials science, geology, and environmental science, making further contributions to unraveling the mysteries of the microscopic world.

[0003] In existing optical microscopes, solid sample holders generally employ a fixed structural design, often providing only a single placement plane and lacking the flexibility to adjust the sample's angle. This makes operation extremely inconvenient when observing the microscopic features of samples from different sides or angles. Researchers typically need to manually flip or move the sample, which not only easily causes sample displacement, affecting the continuity and accuracy of observation, but also, for some small and fragile samples, frequent manual manipulation may damage them, reducing experimental efficiency and success rate.

[0004] While some patents exist for adjustable-angle sample holders, these holders generally suffer from complex structures, cumbersome operation, and high costs, requiring users to possess certain professional knowledge and skills to operate them proficiently. Furthermore, the high cost limits their widespread adoption in ordinary laboratories and educational institutions, hindering their promotion and popularization. Utility Model Content

[0005] This invention provides a rotatable optical microscope solid sample holder, aiming to solve the technical problems of complex structure, cumbersome operation, and high cost that are common in adjustable angle sample holders.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A rotatable optical microscope solid sample holder includes: a base, an annular sample stage supported on the base, a light-transmitting sheet fixing ring at the center of the annular sample stage, a groove in the inner ring of the light-transmitting sheet fixing ring, a light-transmitting sheet embedded in the groove, and multiple fixing holes evenly distributed around the outer ring, each fixing hole including a fixing section and an adjusting section, the inner wall of the fixing section being threaded and the inner wall of the adjusting section being smooth; at least two through holes circumferentially arranged on the side of the annular sample stage, each through hole containing an adjusting bolt, the ends of the multiple adjusting bolts matching the fixing holes of the light-transmitting sheet fixing ring; and a slide holder fixed to the upper surface of the light-transmitting sheet fixing ring.

[0008] Preferably, the upper surface of the base is provided with a mounting hole, and an upwardly extending support rod is threaded into the mounting hole. The top of the support rod is threadedly connected to the bottom of the annular sample stage.

[0009] Preferably, the base is an annular base with an inner diameter of 6cm, an outer diameter of 6.5cm, and a height of 1cm.

[0010] Preferably, the contact surface between the slide holder and the light-transmitting sheet is provided with anti-slip texture.

[0011] Preferably, the base is made of ABS material.

[0012] Preferably, the light-transmitting sheet is made of quartz.

[0013] Preferably, the slide holder is made of silicone.

[0014] Preferably, if the number of perforations is four, the angle between two adjacent perforations is 90 degrees.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] Traditionally, microscopes require manual rotation or movement of the sample to change the viewing angle. This invention allows for multi-angle observation and analysis of the sample directly by adjusting the angle of the lens fixing ring. This avoids sample position shifts caused by manual rotation or movement, which can affect the continuity and accuracy of observation. Furthermore, it prevents damage to small and fragile samples caused by frequent manual operation, improving experimental efficiency and success rate. This invention also features a simple structure, convenient operation, low cost, and improved adjustment flexibility and stability. It is suitable for multi-angle observation and analysis of various solid samples, possessing high practicality and promotional value. Attached Figure Description

[0021] A preferred embodiment of the present invention will now be described in conjunction with the accompanying drawings, providing a clear and complete description of the technical solution in this preferred embodiment.

[0022] A rotatable optical microscope solid sample holder includes: a base 1, an annular sample stage 2 supported on the base 1, a light-transmitting plate fixing ring 3 at the center of the annular sample stage 2, a groove in the inner ring of the light-transmitting plate fixing ring 3, a light-transmitting plate 4 embedded in the groove, and multiple fixing holes 31 evenly distributed around the outer ring, each fixing hole 31 including a fixing section 311 and an adjusting section 312, the inner wall of the fixing section 311 being threaded, and the inner wall of the adjusting section 312 being smooth; at least two through holes 21 oppositely arranged through the annular sample stage 2 are circumferentially opened on the side of the annular sample stage 2, and an adjusting bolt 5 is inserted into each through hole 21, the ends of the multiple adjusting bolts 5 matching the fixing holes 31 of the light-transmitting plate fixing ring 3; a slide holder 6 is fixed on the upper surface of the light-transmitting plate fixing ring 3.

[0023] This invention, through the above design, involves fixing the sample onto a glass slide, then securing the slide to the light-transmitting plate 4 using a slide holder 6. Rotating any two opposing adjusting bolts 5 so that their ends are positioned within the adjusting section 312 of the fixing hole 31 pre-fixes the light-transmitting plate fixing ring 3. Then, rotating the light-transmitting plate fixing ring 3 to the desired angle, and adjusting to the appropriate observation angle, tightens the two adjusting bolts 5, whose ends are within the adjusting section 312, to the fixing section 311. The microscope is then adjusted to begin observation. After testing one angle, if it is necessary to observe the structure of other surfaces, the two opposing adjusting bolts 5 can be loosened so that their ends are outside the fixing hole 31. The light-transmitting plate fixing ring 3 is then rotated, and the two opposing adjusting bolts 5 are reconnected to the fixing hole 31 for further testing. This invention ensures sample stability, avoids sample position shifts, guarantees the continuity and accuracy of observation, and avoids damage to small and fragile samples caused by frequent manual operations, greatly improving experimental efficiency and success rate.

[0025] Through the above design, the support rod 7 is made of stainless steel and has threads at both the top and bottom ends to connect the base and the annular sample stage 2.

[0026] Specifically, the base 1 is an annular seat with an inner diameter of 6cm, an outer diameter of 6.5cm, and a height of 1cm.

[0027] Specifically, the contact surface between the glass slide holder 6 and the light-transmitting sheet 4 is provided with anti-slip texture.

[0028] Through the above design, the slide holder 6 is made of silicone and is fixed to the light-transmitting slide fixing ring 3 with screws. The contact surface between the slide holder 6 and the light-transmitting slide 4 is provided with anti-slip texture to prevent the sample from sliding during the angle adjustment process and affecting the observation.

[0029] Specifically, the base 1 is made of ABS material.

[0030] Specifically, the light-transmitting sheet 4 is made of quartz.

[0031] Specifically, if the number of perforations is four, the angle between two adjacent perforations is 90 degrees.

[0032] Through the above design, the perforations 21 are evenly distributed on the outer ring of the annular sample stage 2, making the adjustment bolt 5 more stable when it passes through the perforations 21 to clamp the light-transmitting sheet fixing ring 3.

[0033] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
