Description

Technical Field

[0001] This utility model belongs to the field of fluorescence microscopy technology, and in particular relates to a fluorescence microscope light shield structure. Background Technology

[0002] A fluorescence microscope uses ultraviolet light as a light source to illuminate the object being examined, causing it to emit fluorescence. The shape and location of the object are then observed under the microscope.

[0003] Existing inverted fluorescence microscopes typically require a light shield to block the light source, facilitating observation and reducing its impact. This light shield is usually mounted on the observation stand as a filter to filter the light. However, when loading and unloading objects, the filter often obstructs the view, making operation difficult. This requires removing the filter, loading / unloading the object, and then reinstalling the filter, increasing the number of steps and making the process cumbersome. Therefore, we propose a new light shield structure for fluorescence microscopes. Utility Model Content

[0004] The purpose of this invention is to provide a fluorescence microscope light shield structure. Specifically, after the filter is installed, when loading or unloading is required, the filter is pulled upwards to a suitable height. Then, the handle is turned clockwise. At this time, the internal threaded moving block, through the connecting frame, drives the arc-shaped clamping block towards the vertical rod and clamps it in place. The filter is thus fixed, facilitating loading and unloading operations without requiring filter disassembly, reducing operational steps and increasing efficiency. Furthermore, the U-shaped filter can filter more light sources, improving the light-shielding effect. This solves the problem that when loading or unloading objects, the filter usually blocks the view, making operation difficult and requiring filter disassembly, object loading / unloading, and then filter reinstallation, thus increasing operational steps.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model relates to a fluorescence microscope light shield structure, including an observation stage. A positioning bracket is fixedly connected to the top of the observation stage. A light shielding component is provided above the observation stage. The light shielding component includes a filter, which is U-shaped. A fixing component is provided on the back left side of the filter. The fixing component includes a fixing block fixedly connected to the back of the filter. Two vertical rods are fixedly connected to the rear of the top of the observation stage. A rotating hole and a square sliding groove are opened inside the fixing block. A threaded rod is rotatably connected to the rotating hole on the fixing block. An internally threaded moving block is threadedly connected to the outer surface of the threaded rod. A handle is fixedly connected to the left side of the threaded rod. A connecting frame is fixedly connected to the front of the internally threaded moving block. An arc-shaped clamping block is fixedly connected to one end of the front of the connecting frame.

[0007] Furthermore, two limiting rings are fixedly connected to the outer surface of the threaded rod. The two limiting rings are distributed on the left and right sides of the fixing block. The left side of the connecting frame passes through the fixing block and extends to the outside. The connecting frame slides and limits the connection with the square groove on the fixing block. The arc-shaped clamp is arc-shaped.

[0008] Furthermore, a rubber pad is fixedly connected to the bottom of the filter cover, and the bottom of the rubber pad contacts the top of the observation platform. Circular grooves are provided on both the left and right sides of the filter cover.

[0009] Furthermore, both vertical rods are provided with disassembly components on their outer sides. Each disassembly component includes a docking block. A connecting block is fixedly connected to the side of the docking block near the filter cover, and a slider is fixedly connected to the side of the connecting block away from the docking block. A storage groove is provided on the side of the docking block near the filter cover, and a threaded knob is threadedly connected inside the storage groove. A clamp is fixedly connected to the side of the threaded knob near the filter cover.

[0010] Furthermore, a docking groove is formed on the corresponding side of the docking block and the slider, the docking groove is inserted into the top of the filter cover, a sliding hole is opened inside the slider, the slider slides and limits the vertical rod through the sliding hole, the outer side of the clamping plate is adapted to the inner wall of the storage groove, the clamping plate is positioned and cooperates with the circular groove, and the bottom of the connecting block contacts the top of the filter cover.

[0011] This utility model has the following beneficial effects:

[0012] 1. This utility model features a fixed component. Specifically, after the filter is installed, when loading or unloading is required, the filter is pulled upwards to a suitable height. Then, the handle is turned clockwise. At this time, the internal thread moving block will drive the arc-shaped clamping block to approach and clamp the filter at the vertical position through the connecting frame. The filter is thus fixed, which facilitates loading and unloading operations without disassembling the filter, reducing operation steps and increasing efficiency. In addition, the U-shaped filter can filter more light sources and improve the light-blocking effect.

[0013] 2. This utility model features a disassembly assembly. Specifically, the operator moves the clamping plate into the storage slot by turning the threaded knob counterclockwise. At this time, the clamping plate leaves the circular slot, thereby releasing the filter cover from its fixation. Then, the connecting block is pulled upward, moving the slider together to release the filter cover's limit, allowing the filter cover to be pulled out and disassembled for replacement. This method is simple and convenient to operate, facilitating subsequent maintenance and other work.

[0014] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

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 scope of protection of the present utility model.

[0025] Please see Figures 1-6 As shown, this utility model is a fluorescent microscope light shield structure, including an observation stage 1. A positioning bracket 2 is fixedly connected to the top of the observation stage 1. A light shielding component 11 is provided above the observation stage 1. The light shielding component 11 includes a filter 111, which is U-shaped. A fixing component 13 is provided on the back left side of the filter 111. The fixing component 13 includes a fixing block 131 fixedly connected to the back of the filter 111. Two vertical rods 12 are fixedly connected to the rear of the top of the observation stage 1. The fixing block 131 has a rotating hole and a square sliding groove inside. A threaded rod 132 is rotatably connected to the rotating hole on the fixing block 131. An internal threaded moving block 133 is threadedly connected to the outer surface of the threaded rod 132. A handle 322 is fixedly connected to the left side of the threaded rod 132. A connecting frame 134 is fixedly connected to the front of the internal threaded moving block 133. An arc-shaped clamping block 135 is fixedly connected to one end of the front of the connecting frame 134.

[0026] Two limiting rings 321 are fixedly connected to the outer surface of the threaded rod 132. The two limiting rings 321 are distributed on the left and right sides of the fixing block 131. The left side of the connecting frame 134 passes through the fixing block 131 and extends to the outside. The connecting frame 134 slides and limits the connection with the square groove on the fixing block 131. The arc-shaped clamping block 135 is arc-shaped.

[0027] A rubber pad 112 is fixedly connected to the bottom of the filter cover 111. The bottom of the rubber pad 112 contacts the top of the observation table 1. Circular grooves 113 are provided on the left and right sides of the filter cover 111.

[0028] Both vertical rods 12 are equipped with disassembly components 14 on their outer sides. The disassembly components 14 include a docking block 141. A connecting block 142 is fixedly connected to the side of the docking block 141 near the filter cover 111. A slider 143 is fixedly connected to the side of the connecting block 142 away from the docking block 141. A storage groove 145 is opened on the side of the docking block 141 near the filter cover 111. A threaded knob 144 is threadedly connected inside the storage groove 145. A clamp 441 is fixedly connected to the side of the threaded knob 144 near the filter cover 111.

[0029] A docking groove is formed on the corresponding side of the docking block 141 and the slider 143. The docking groove is inserted into the top of the filter cover 111. A sliding hole is opened inside the slider 143. The slider 143 slides and limits the vertical rod 12 through the sliding hole. The outer side of the clamping plate 441 is adapted to the inner wall of the storage groove 145. The clamping plate 441 is positioned and engaged with the circular groove 113. The bottom of the connecting block 142 contacts the top of the filter cover 111.

[0030] One specific application of this embodiment is:

[0031] In use, place the filter 111 on the observation table 1. Push and pull the slider 143 as needed to move it to the top position of the filter 111, where it engages with the mating block 141. Then, turn the threaded knob 144 clockwise to move the clamping plate 441 and adjust the position of the filter 111 so that the clamping plate 441 smoothly enters the circular groove 113, thereby clamping and fixing the filter 111. After the slider 143 and the mating block 141 are engaged with the filter 111, the connecting block 1... The bottom of 42 contacts the top of the filter 111, positioning it and ensuring it is horizontal after installation. The other side of the filter 111 is then fixed in the same way to complete the installation. When loading or unloading on the observation table 1, pull the filter 111 upwards. This will cause the slider 143 to slide on the vertical rod 12, moving the filter 111 to the top. Once the desired height is reached, turn the handle 322 clockwise. This will cause the internal thread moving block 133 to... The filter 111 moves along the threaded rod 132 and, through the connecting frame 134, moves the arc-shaped clamping block 135 closer to the vertical rod 12. Since the connecting frame 134 slides within the fixed block 131, the arc-shaped clamping block 135 moves linearly. When the arc-shaped clamping block 135 contacts the surface of the vertical rod 12, it clamps and fixes the filter 111 at a high position, allowing workers to load and unload materials without obstruction, making loading and unloading more convenient and efficient. When observation is required after loading, turn the handle 322 counterclockwise. Move the arc-shaped clamp 135 away from the vertical rod 12 to release the fixation of the filter cover 111. Then pull the filter cover 111 down. Stop when the rubber pad 112 at the bottom of the filter cover 111 contacts the top of the observation table 1. At this time, the filter cover 111 filters the light source and plays a role in blocking light, making it more convenient for staff to observe. The rubber pad 112 is set to protect the filter cover 111 and the observation table 1 from being scratched. The filter cover 111 is U-shaped, which can filter more light sources and improve the light blocking effect.

[0032] When the filter 111 needs to be replaced, the operator turns the threaded knob 144 counterclockwise to move the clamp 441 into the storage slot 145 for storage, thereby releasing the filter 111 from the fixation. Then, the docking block 141 is pulled upward, moving together with the slider 143 to release the limit of the filter 111, so that the filter 111 can be pulled out and disassembled for replacement.
