[0001] This utility model relates to the field of laser scanning confocal microscopy technology, and in particular to a sample tilt angle adjustment mechanism for laser scanning confocal microscopy. Background Technology

[0002] Laser scanning confocal microscopes use a laser beam as a light source. The laser beam passes through an illumination pinhole, is reflected by a beam splitter to the objective lens, and is focused on the sample to scan every point on the focal plane of the specimen.

[0003] Regarding the above and existing related technologies, the inventors believe that the following defects often exist: the existing sample tilt angle adjustment mechanism cannot adjust the tilt angle of the sample as needed during use, resulting in poor sample observation and affecting the accuracy of the experiment. Utility Model Content

[0004] The technical problem to be solved by this invention is that the existing sample tilt angle adjustment mechanism cannot adjust the tilt angle of the sample as needed, resulting in poor sample observation and affecting the accuracy of the experiment. To address this, we propose a sample tilt angle adjustment mechanism for a laser scanning confocal microscope.

[0005] To achieve the above objectives, this application adopts the following technical solution: a sample tilt angle adjustment mechanism for a laser scanning confocal microscope, comprising a base plate: a microscope body is fixedly connected to the top of the base plate, two fixed plates are fixedly connected to the top of the base plate, a movable block is rotatably connected to the internal shaft of the fixed plate, a connecting block is fixedly connected to the top of the movable block, a U-shaped block is installed on the top of the connecting block, a placement plate is fixedly connected to the top of the U-shaped block, a plurality of insertion holes are opened on one side of the connecting block, an insertion hole is opened on one side of the fixed plate, an insertion rod is slidably connected inside the insertion hole, and a pull block is fixedly connected to one side of the insertion rod.

[0006] Preferably, a return spring is fixedly connected to one side of the pull block, and one side of the return spring is fixedly connected to one side of the fixed plate.

[0007] Preferably, the surface of the plug rod is slidably connected to the inside of the plug hole, and the outer diameter of the plug rod is adapted to the inner diameter of the plug hole.

[0008] Preferably, an arc-shaped guide groove is provided on one side of the movable block, and an arc-shaped guide block is fixedly connected to the other side of the fixed plate. The interior of the arc-shaped guide groove is slidably connected to the surface of the arc-shaped guide block.

[0009] Preferably, the U-shaped block has slots on both sides, the connecting block has openings on both sides, a storage spring is fixedly connected inside the opening, and a locking block is fixedly connected to one side of the storage spring.

[0010] Preferably, both ends of the groove cavity are provided with sliding grooves, and both ends of the block are fixedly connected with sliders.

[0011] The technical effects and advantages of this utility model are as follows:

[0012] In this invention, the operator pulls a lever, which causes the insertion rod to slide inside the insertion hole. The insertion rod moves out of the insertion hole, releasing the fixing of the connecting block. At this point, rotating the connecting block causes the movable block to rotate inside the fixed plate. The movable block then rotates the placement plate, which in turn rotates the sample, thus adjusting the sample's tilt angle. After adjustment, moving the lever inserts the insertion rod into the insertion hole, fixing the connecting block in place. This completes the adjustment of the sample's tilt angle, facilitating observation of the sample at different tilt angles and increasing its practicality. Attached Figure Description

[0020] It is readily understood that, based on the technical solution of this utility model, those skilled in the art can propose various interchangeable structural methods and implementation methods without changing the essential spirit of this utility model. Therefore, the following specific embodiments and accompanying drawings are merely exemplary descriptions of the technical solution of this utility model, and should not be regarded as the entirety of this utility model or as a limitation or restriction on the technical solution of this utility model.

[0021] Reference Figures 1-4 As shown, this utility model provides a technical solution: a sample tilt angle adjustment mechanism for a laser scanning confocal microscope, comprising a base plate 1; a microscope body 2 is fixedly connected to the top of the base plate 1; two fixed plates 3 are fixedly connected to the top of the base plate 1; a movable block 4 is rotatably connected to the internal shaft of the fixed plate 3; a connecting block 5 is fixedly connected to the top of the movable block 4; a U-shaped block 6 is installed on the top of the connecting block 5; a placement plate 7 is fixedly connected to the top of the U-shaped block 6; multiple insertion holes 8 are opened on one side of the connecting block 5; an insertion hole 9 is opened on one side of the fixed plate 3; an insertion rod 10 is slidably connected inside the insertion hole 9; and a pull block is fixedly connected to one side of the insertion rod 10. 11. By pulling the pull block 11, the staff can cause the insertion rod 10 to slide inside the insertion hole 9. The insertion rod 10 moves out of the insertion hole 8, releasing the fixation of the connecting block 5. At this time, the connecting block 5 is rotated, which causes the movable block 4 to rotate inside the fixed plate 3. The movable block 4 causes the placement plate 7 to rotate, and the placement plate 7 causes the sample to rotate, thus achieving the purpose of adjusting the tilt angle of the sample. After the adjustment is completed, the pull block 11 is moved to lock the insertion rod 10 into the insertion hole 8, fixing the connecting block 5. This completes the adjustment of the tilt angle of the sample, making it easier for the staff to observe the sample at different tilt angles and increasing its practicality.

[0022] Reference Figure 3 As shown in this embodiment: a return spring 12 is fixedly connected to one side of the pull block 11, and one side of the return spring 12 is fixedly connected to one side of the fixing plate 3. With the setting of the return spring 12, after the fixing of the connecting block 5 is released, the elastic force of the return spring 12 can push the pull block 11 to reset, and the pull block 11 drives the plug rod 10 to reset, which facilitates the fixing of the connecting block 5 next time. There is no need for the staff to manually move the plug rod 10 to reset, which increases convenience.

[0023] Reference Figure 2 and Figure 3As shown in this embodiment: the surface of the plug rod 10 is slidably connected to the inside of the plug hole 8, and the outer diameter of the plug rod 10 is adapted to the inner diameter of the plug hole 8. Through the sliding connection design between the plug rod 10 and the plug hole 8, the stability of the plug rod 10 moving inside the plug hole 8 is ensured. At the same time, the matching of the outer diameter of the plug rod 10 with the inner diameter of the plug hole 8 further improves the smoothness and tightness of the plug rod 10 moving inside the plug hole 8, avoiding the situation of the plug rod 10 shaking or getting stuck inside the plug hole 8, thereby ensuring the stability and reliability of the connection block 5.

[0024] Reference Figure 2 and Figure 3 As shown in this embodiment: an arc-shaped guide groove 13 is provided on one side of the movable block 4, and an arc-shaped guide block 14 is fixedly connected to the other side of the fixed plate 3. The interior of the arc-shaped guide groove 13 is slidably connected to the surface of the arc-shaped guide block 14. The arc-shaped guide block 14 slides smoothly in the arc-shaped guide groove 13, providing precise guidance for the movement of the movable block 4 and ensuring that the sample stage remains stable and accurate when the tilt angle is adjusted.

[0025] Reference Figure 5 As shown in this embodiment: slots 16 are provided on both sides of the U-shaped block 6, and slots 17 are provided on both sides of the connecting block 5. A storage spring 18 is fixedly connected inside the slot 17, and a locking block 19 is fixedly connected to one side of the storage spring 18. By pressing the locking block 19, the locking block 19 is moved to retract into the slot 17, thereby releasing the fixed relationship between the connecting block 5 and the U-shaped block 6. This allows the shelf 7 to be disassembled relative to the connecting block 5, making the replacement and maintenance of the shelf 7 more convenient and improving the flexibility and maintainability of the equipment.

[0026] Reference Figure 5 As shown in this embodiment: both ends of the inner cavity of the slot 17 are provided with sliding grooves 20, and both ends of the locking block 19 are fixedly connected with sliders 21. The sliders 21 slide smoothly inside the sliding grooves 20, which limits the movement of the locking block 19 and prevents the locking block 19 from deviating during the movement. This ensures that the locking block 19 can be stably driven to move, thereby making the connection between the connecting block 5 and the U-shaped block 6 more stable to be released or established, improving the stability and reliability of the equipment.

[0027] Working principle: By pulling the pull block 11, the operator causes the insertion rod 10 to slide inside the insertion hole 9, moving it out of the insertion hole 8 and releasing the fixing of the connecting block 5. At this point, rotating the connecting block 5 causes the movable block 4 to rotate inside the fixed plate 3, which in turn rotates the placement plate 7, which in turn rotates the sample, thus adjusting the sample tilt angle. After adjustment, moving the pull block 11 inserts the insertion rod 10 into the insertion hole 8, fixing the connecting block 5, thereby completing the sample tilt adjustment. The adjustable tilt angle facilitates observation of samples at different tilt angles, increasing practicality. The reset spring 12, after releasing the fixing of the connecting block 5, pushes the pull block 11 back to its original position, which in turn resets the insertion rod 10. This facilitates the next fixing of the connecting block 5 without requiring manual movement of the insertion rod 10, increasing convenience. The sliding connection design between the insertion rod 10 and the insertion hole 8 ensures the stability of the insertion rod 10's movement within the insertion hole 8. Furthermore, the outer diameter of the insertion rod 10 is consistent with... The inner diameter of the insertion hole 8 is matched, further improving the smoothness and tightness of the movement of the insertion rod 10 inside the insertion hole 8, avoiding the insertion rod 10 from shaking or getting stuck inside the insertion hole 8, thus ensuring the stability and reliability of the connecting block 5. The arc-shaped guide block 14 slides smoothly in the arc-shaped guide groove 13, providing precise guidance for the movement of the movable block 4, ensuring that the sample stage remains stable and accurate when adjusting the tilt angle. By pressing the locking block 19, the locking block 19 is moved to retract into the groove 17, so that the connecting block 5 and the U-shaped block 6 are connected. The fixed relationship between the two is released, allowing the shelf 7 to be disassembled relative to the connecting block 5. This makes the replacement and maintenance of the shelf 7 more convenient, improving the flexibility and maintainability of the equipment. The slider 21 slides smoothly inside the slide groove 20, limiting the movement of the locking block 19 and preventing the locking block 19 from deviating during movement. This ensures that the locking block 19 can be stably driven to move, thereby making the connection between the connecting block 5 and the U-shaped block 6 more stable to be released or established, improving the stability and reliability of the equipment.

[0028] The technical scope of this utility model is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the protection scope of this utility model.
