Description

Technical Field

[0001] This application relates to the field of optical microscopy technology, and more particularly to an optical microscope sample observation stage. Background Technology

[0002] An optical microscope is an optical instrument that uses optical principles to magnify and image tiny objects that are indistinguishable to the human eye, allowing people to extract information about their fine structures. The optical microscope stage is an important component of an optical microscope. It is used to place and fix the sample to be observed. When using an optical microscope, the sample needs to be placed on the stage and fixed with clips or other fixing devices to ensure that the sample does not move during the observation process. This is quite common in daily life.

[0003] Existing technologies, such as the utility model patent with publication number CN219778031U, disclose a microscope stage. This patent includes a microscope support and a microscope stage. A focusing stage is positioned above the microscope support, and a trinocular observation tube is positioned above the focusing stage. An optical tube is positioned on one side of the trinocular observation tube, and an image sensor is positioned above the optical tube. An objective lens turret is positioned directly below the trinocular observation tube, and an objective lens is positioned below the objective lens turret. An eyepiece is positioned on one side of the trinocular observation tube, and the microscope stage is positioned below the objective lens using a snap-fit ​​mechanism. The microscope stage includes a fixing rod, an illumination lamp, a bearing, a slide, a sliding groove, a heating coil, a guide groove, a rotating shaft, and a rubber pad. This device provides a light source through the illumination lamp. Compared to traditional optical microscopes, this device does not require adjustment of the mirror position, and the light intensity can be adjusted via the illumination lamp, thus facilitating observation of substances on the slide.

[0004] In daily use, it has been found that when operating an optical microscope, the limited surface space of the typical microscope stage makes it inconvenient to press and fix large observation slides, thus hindering the effective operation of the optical microscope. Utility Model Content

[0005] One of the technical problems this application aims to solve is that, during the operation of an optical microscope, due to the limited surface space of a typical microscope observation stage, it is inconvenient to squeeze and fix large observation sample slides, thus making it impossible to effectively operate the optical microscope.

[0006] To solve the above-mentioned technical problems, embodiments of this application provide an optical microscope sample observation stage, including: a base, and an observation stage mounted on the upper surface of the base;

[0007] The telescope arm is located on one side of the base surface, and the bottom end of the telescope arm is fixedly connected to the surface of the base.

[0008] The converter objective lens module is located on the upper surface of the telescope arm;

[0009] A reflector is installed on the base surface at a position corresponding to the observation platform.

[0010] The adjustment mechanism is located on the observation stage surface near the telescope arm; and

[0011] A positioning mechanism is located on one side of the observation platform;

[0012] The adjustment mechanism includes a support plate, the lower surface of which abuts against the surface of the observation platform. Slide plates are fixedly connected to both sides of the lower surface of the support plate. Slide grooves are formed on both sides of the surface of the observation platform, with the inner walls of the grooves slidably connected to the surfaces of the slide plates. The slide plates have a "T"-shaped cross-section. Mounting columns are fixedly connected to both sides of the surface of the observation platform. Limiting rings are movably connected to the arc surfaces of the mounting columns, with semi-circular cross-sections. Limiting grooves are formed on the side walls of the support plate corresponding to the positions of the limiting rings, with the inner walls of the grooves engaging with the surfaces of the limiting rings. The positioning mechanism includes a positioning frame, with sliding holes on the side walls of the positioning frame. An insert block is slidably connected to the inner wall of the sliding hole, with an I-shaped cross-section. A moving rod slides through the inner wall of the insert block, with one end of the moving rod fixedly connected to a mounting plate. A sliding rod is fixedly connected to the upper surface of the mounting plate, with a pressure plate slidably connected to the arc surface of the sliding rod. A tension spring is fitted onto the arc surface of the sliding rod, with both ends of the tension spring fixedly connected to the surfaces of the sliding rod and the pressure plate, respectively.

[0013] In some embodiments, the adjustment mechanism further includes a positioning block, the surface of which is fixedly connected to the arc surface of the mounting column, and the inner wall of the limiting ring is provided with a positioning groove, the inner wall of which is slidably connected to the surface of the positioning block.

[0014] In some embodiments, two connecting grooves are provided on the side of the support plate away from the mounting column, and connecting blocks are inserted into the inner walls of both connecting grooves. An auxiliary groove is provided on the side wall of the observation platform corresponding to the position of the connecting block. The inner wall of the auxiliary groove is inserted into the surface of the connecting block. A protective ring is sleeved on the bottom arc surface of the connecting block, and a fixed shaft is threaded to the bottom arc surface of the connecting block.

[0015] In some embodiments, a protective sleeve is fixedly connected to the arc surface of the limiting ring away from the bearing plate, and the protective sleeve is a rubber sleeve.

[0016] In some embodiments, the positioning mechanism further includes a pressing plate, the surface of which is fixedly connected to the side of the moving rod away from the mounting plate. The pressing plate has a tapered cross-section and a friction pad is fixedly connected to the tapered surface of the pressing plate. A plurality of locking blocks are fixedly connected to the inner wall of the positioning frame. The locking blocks have a pointed conical cross-section and their surfaces engage with the surface of the pressing plate.

[0017] In some embodiments, a spring is fitted onto the arcuate surface of the moving rod, and the two ends of the spring are fixedly connected to the insert block and the extrusion plate, respectively.

[0018] In some embodiments, a pull ring is rotatably connected to one side surface of the mounting plate, and the cross-sectional dimensions of the pull ring are adapted to the cross-sectional dimensions of the mounting plate.

[0019] The above technical solution makes it more convenient to operate and use optical microscopes. Since the traditional microscope stage has limited space and is only suitable for observing small samples, the adjustment mechanism set on the observation stage surface can effectively increase the size of the stage surface, so as to accommodate the placement and observation of a whole UTG glass product. This helps to break through the space limitations of the traditional stage. At the same time, the positioning mechanism installed on one side of the observation stage surface can be used for auxiliary operation, which makes it easy to squeeze and limit the observation sample glass slide.

[0040] Positioning mechanism 7 is located on one side of observation platform 5.

[0041] The specific setup and function of the adjustment mechanism 6 and the positioning mechanism 7 will be explained in detail below.

[0042] Reference Figure 3 and Figure 4As shown in this embodiment: the adjustment mechanism 6 includes a support plate 601, the lower surface of which abuts against the surface of the observation platform 5. The support plate 601 can increase the area of ​​the original observation platform 5. Slide plates 602 are fixedly connected to both sides of the lower surface of the support plate 601. The sliding between the slide plates 602 and the slide grooves 603 can limit the position of the support plate 601. Slide grooves 603 are provided on both sides of the surface of the observation platform 5. The inner wall of the slide grooves 603 is slidably connected to the surface of the slide plates 602. The cross-section of the slide plates 602 is "T" shaped to prevent the slide plates 602 from detaching from the slide grooves 603. The observation platform 5 has mounting posts 604 fixedly connected to both sides of its surface. The mounting posts 604 can move and limit the position of the limiting ring 606. The arc surface of the mounting post 604 is movably connected to the limiting ring 606. The limiting ring 606 can engage with the limiting groove 605 opened on the side wall of the support plate 601. The limiting ring 606 has a semi-circular cross-section. The side wall of the support plate 601 has a limiting groove 605 corresponding to the position of the limiting ring 606. The inner wall of the limiting groove 605 engages with the surface of the limiting ring 606. The adjustment mechanism 6 also includes a positioning block 609. The surface of the positioning block 609 is in contact with the mounting post 606. The arc surface of column 604 is fixedly connected, and the insertion between positioning block 609 and positioning groove 607 can lock and fix the position of limiting ring 606 to prevent displacement. The inner wall of limiting ring 606 has positioning groove 607, and the inner wall of positioning groove 607 is slidably connected to the surface of positioning block 609. Two connecting grooves 610 are opened on the side of bearing plate 601 away from mounting column 604. Connecting blocks 611 are inserted into the inner walls of both connecting grooves 610. An auxiliary groove 612 is opened on the side wall of observation platform 5 corresponding to the position of connecting block 611. The auxiliary groove 612 and the connecting groove 610 are connected to the connecting blocks. 611 is snapped in place. The inner wall of the auxiliary groove 612 is inserted into the surface of the connecting block 611. A protective ring 613 is fitted on the bottom arc surface of the connecting block 611. The protective ring 613 can prevent the fixing shaft 614 from loosening and falling off. The bottom arc surface of the connecting block 611 is threadedly connected to the fixing shaft 614. The fixing shaft 614 can press and fix the position of the connecting block 611. A protective sleeve 608 is fixedly connected to the arc surface of the limiting ring 606 away from the bearing plate 601. The protective sleeve 608 can better rotate the limiting ring 606. The protective sleeve 608 is a rubber sleeve.

[0043] Reference Figure 5As shown, in this embodiment: the positioning mechanism 7 includes a positioning frame 701, a sliding hole 703 is provided on the side wall of the positioning frame 701, an insert block 709 is slidably connected to the inner wall of the sliding hole 703, the insert block 709 can slide along the sliding hole 703, the cross-section of the insert block 709 is I-shaped, a moving rod 706 slidably passes through the inner wall of the insert block 709, the moving rod 706 can fix and limit the mounting plate 704, one end of the moving rod 706 is fixedly connected to the mounting plate 704, the mounting plate 704 can... To fix the position of the pressure plate 712, a slide rod 710 is fixedly connected to the upper surface of the mounting plate 704. The slide rod 710 can slide and limit the pressure plate 712. The pressure plate 712 is slidably connected to the arc surface of the slide rod 710. A tension spring 711 is sleeved on the arc surface of the slide rod 710. The compressive force generated by the tension spring 711 can compress and fix the pressure plate 712. The two ends of the tension spring 711 are fixedly connected to the surfaces of the slide rod 710 and the pressure plate 712, respectively. The positioning mechanism 7 also includes a pressing plate 705. The pressure plate 705 can engage and fix the locking block 702 to prevent the moving rod 706 from shifting position. The surface of the pressure plate 705 is fixedly connected to the side of the moving rod 706 away from the mounting plate 704. The cross-section of the pressure plate 705 is conical, and a friction pad 708 is fixedly connected to the conical surface of the pressure plate 705. Several locking blocks 702 are fixedly connected to the inner wall of the positioning frame 701. The locking blocks 702 facilitate engagement with the pressure plate 705. The cross-section of the locking blocks 702 is pointed and conical. The surface of the moving rod 706 is engaged with the surface of the extrusion plate 705. The arc surface of the moving rod 706 is fitted with a spring 707. The tensile force generated by the spring 707 can stretch and fix the position of the moving rod 706. The two ends of the spring 707 are fixedly connected to the insert block 709 and the extrusion plate 705 respectively. A pull ring is rotatably connected to one side surface of the mounting plate 704. The pull ring can easily stretch and move the positions of the moving rod 706 and the mounting plate 704. The cross-sectional dimensions of the pull ring are adapted to the cross-sectional dimensions of the mounting plate 704.

[0044] During the operation of an optical microscope, the observation stage 5 is usually small, making it inconvenient to place and observe large observation slides. In this case, the adjustment mechanism 6 can be used to increase the area of ​​the observation stage 5. First, the fixing plate is inserted into the groove 603 on the surface of the observation stage 5 using the sliding plate 602 on its lower surface. Then, the limiting ring 606 on the arc surface of the mounting post 604 on the surface of the observation stage 5 is rotated to engage with the limiting groove 605 on the side wall of the support plate 601. At this point, the entire support plate 601 is fixed to the surface of the observation stage 5. Next, the connecting block 611 is inserted into the connecting groove 610 on the other side of the support plate 601 and the auxiliary groove 612 on the side wall of the observation stage 5, and simultaneously pressed and fixed using the fixing shaft 614. At this point, the entire support plate 601 is fixed to the surface of the observation stage 5, preventing any positional shift.

[0045] When the observation sample slide is placed on the surface of the support plate 601, in order to facilitate the compression and fixation of the observation sample slide, the positioning mechanism 7 is used for auxiliary operation. First, the inlay block 709 on the side wall of the positioning frame 701 is pulled, so that the inlay block 709 slides along the sliding hole 703. At the same time, the moving rod 706 on the surface of the inlay block 709 is stretched, which will drive the entire mounting plate 704 to move. This facilitates the horizontal movement of the pressure piece 712 sliding on the surface of the upper sliding rod 710 of the mounting plate 704. After reaching the designated position, the compression plate 705 fixed at one end of the moving rod 706 is engaged and fixed with the locking block 702 fixed on the inner wall of the positioning frame 701, so as to effectively adjust and fix the position of the pressure piece 712.
