Align the components, then insert the fixing plate 14 onto the guide rail 12. When one side of the fixing plate 14 contacts the baffle 13, the fixing assembly will fix the staining assembly onto the top of the inspection box 1. Then, place multiple sets of slides on the surface of the carrier plate 16 and push each set of slides into a set of locking teeth 17 to lock the slides onto the carrier plate 16. Then, perform the staining operation on the slides. When staining slides of different sizes, the spacing between the locking teeth 17 on different staining assemblies is different. By replacing the staining assembly on the inspection box 1 with one of the corresponding size to the slide, the above structure, which includes the inspection box 1, extension frame 11, guide rail 12, baffle 13, and staining assembly, allows for the simultaneous fixing of multiple sets of slides, thereby improving the operational efficiency during staining. At the same time, the different spacing between the locking teeth 17 on multiple sets of staining assemblies, and the sliding fit between the staining assembly and the inspection box 1, can adapt to the staining of slides of different sizes, thereby improving the applicability of the overall device.
[0026] like Figure 2As shown, the collection assembly includes a guide tray 2; the guide tray 2 is fixed to the inner wall of the inspection box 1; a drain outlet 21 is provided in the middle of the guide tray 2; the guide tray 2 has an inclined structure; a drawer box 22 is slidably installed inside the inspection box 1; a silicone pad 23 is provided on the top of the drawer box 22; during operation, after the slides are stained, they need to be rinsed. At this time, the operator rotates the fixing plate 14 to an inclined state by rotating the assembly, and then uses a rinsing bottle to rinse the slides. The wastewater generated at this time flows downward into the guide tray 2, and then the wastewater flows towards the drain outlet 21 along the inclination of the drain outlet 21. The wastewater is collected in the lower drawer 22. After collection, the drawer 22 is removed from the inspection box 1, the collected wastewater is poured out, and then the drawer 22 is inserted back into the inspection box 1. At this time, the silicone pad 23 on the top of the drawer 22 contacts the inspection box 1, and the drawer 22 is fixed in the inspection box 1 by friction. With the above structure, the guide plate 2, the drain outlet 21, the drawer 22 and the silicone pad 23 are set to facilitate the collection and removal of wastewater generated after rinsing. At the same time, the inclined structure of the drain outlet 21 can guide the wastewater and reduce the residue of wastewater on the guide plate 2.
[0027] like Figure 2 As shown, the storage assembly includes a storage box 3; the storage box 3 is fixed to the side wall of the test box 1; multiple partitions 31 are installed inside the storage box 3; during operation, reagent bottles, rinsing bottles and other containers are placed in the areas separated by the partitions 31 inside the storage box 3. Through the above structure, the storage box 3 and the partitions 31 are set up, and the storage box 3 can be divided into multiple areas by the partitions 31, so as to facilitate the classification and placement of reagent bottles, rinsing bottles and other containers for easy access by users.
[0028] like Figures 3 to 5As shown, the rotating assembly includes a rotating shaft 4; the rotating shaft 4 is rotatably connected to a fixed plate 14; the carrying plate 16 is fixedly connected to the rotating shaft 4; a sliding sleeve 41 is slidably connected to the rotating shaft 4; a spring 42 is fixedly connected to both the sliding sleeve 41 and the rotating shaft 4; two sets of slots 43 are provided inside the sliding sleeve 41; a set of horizontal limiting strips 44 are fixedly connected to the side wall of the rotating shaft 4; a set of oblique limiting strips 45 are fixedly connected to the side wall of the fixed plate 14; a horizontal positioning plate 46 and an oblique positioning plate 45 are fixedly connected to the inner side wall of the fixed plate 14. Plate 47; During operation, when rinsing the glass slide, the fixed plate 14 can be rotated to an inclined state. At this time, by pulling the sliding sleeve 41 outward and compressing the spring 42, a set of slots 43 will be engaged with the horizontal limiting strip 44. Then, rotating the sliding sleeve 41 will drive the rotating shaft 4 and the fixed plate 14 to rotate. When the fixed plate 14 contacts the inclined positioning plate 47, the horizontal limiting strip 44 and the inclined limiting strip 45 will be aligned. At this time, the sliding sleeve 41 will be released, and under the rebound of the spring 42, the sliding sleeve 41 will move to one side of the fixed plate 14, and the set of slots 43 will be engaged with the horizontal limiting strip 44. The groove 43 is engaged within the inclined limiting strip 45, thus securing the sliding sleeve 41 to the rotating shaft 4 and the fixing plate 14. After rinsing, the sliding sleeve 41 is pulled again, and the spring 42 is compressed, causing a set of grooves 43 to disengage from the inclined limiting strip 45. Then, the sliding sleeve 41 is reversed, causing the rotating shaft 4 and the fixing plate 14 to reverse. When the fixing plate 14 contacts the horizontal positioning plate 46, the fixing plate 14 is in a horizontal state. Then, the sliding sleeve 41 is released, and under the rebound of the spring 42, the sliding sleeve 41 moves towards the fixing plate 14, causing another set of grooves 43 to engage. The sliding sleeve 41 and the fixed plate 14 can be fixed in place by the inclined limiting strip 45. Through the above structure, the rotating shaft 4, sliding sleeve 41, spring 42, slot 43, horizontal limiting strip 44, and inclined limiting strip 45 are set up. Together with the horizontal positioning plate 46 and the inclined positioning plate 47, it is convenient to make the fixed plate 14 tilted when rinsing the glass slide, so that the sewage can flow downward during rinsing. When tilted, the position of the fixed plate 14 is locked, which can reduce the inconvenience of the operator having to hold it with their hand all the time.
[0029] like Figure 2 and Figure 4 As shown, the fixing assembly includes a first magnet 5 and a second magnet 51; the first magnet 5 is installed on the top of the inspection box 1; the second magnet 51 is installed on the bottom of the fixing plate 14; during operation, when the fixing plate 14 slides on the guide rail 12, the first magnet 5 and the second magnet 51 are attracted to each other. When the fixing plate 14 contacts the baffle 13, the first magnet 5 and the second magnet 51 are attracted together, which can fix the position of the fixing plate 14. Through the above structure, the first magnet 5 and the second magnet 51 are set to facilitate the fixing and disassembly of the fixing plate 14 on the guide rail 12, thereby improving the convenience when changing the dyeing assembly.
[0030] like Figure 3As shown, the carrier plate 16 has a plurality of drainage holes 6; the plurality of drainage holes 6 are evenly distributed on the carrier plate 16; during operation, some of the wastewater generated when rinsing the glass slide will fall from the drainage holes 6. Through the above structure, the provision of multiple drainage holes 6 can reduce the residual wastewater on the fixing plate 14.
[0031] like Figure 5 As shown, a silicone sleeve 7 is installed on the outside of the sliding sleeve 41; the silicone sleeve 7 is provided with anti-slip texture; during operation, when the operator rotates the sliding sleeve 41, his hand will come into contact with the silicone sleeve 7. Through the above structure, the silicone sleeve 7 can increase the friction between the operator's hand and the sliding sleeve 41, thereby improving the stability when rotating the sliding sleeve 41.
[0032] Working principle: Align the slide 15 with the guide rail 12, then insert the fixing plate 14 into the guide rail 12. When one side of the fixing plate 14 contacts the baffle 13, the fixing assembly will fix the staining assembly on the top of the test box 1. Then, place multiple sets of slides on the surface of the carrier plate 16 and push each set of slides into a set of retaining teeth 17 to secure the slides on the carrier plate 16. Then, perform the staining operation on the slides. When staining slides of different sizes, the spacing between the retaining teeth 17 on different staining assemblies is different. This can be achieved by replacing the staining assembly on the test box 1 with one of the corresponding sizes for the slides. After staining, the slides need to be rinsed. At this time, the operator rotates the fixing plate 14 to tilt by rotating the assembly. The slide is then rinsed using a rinsing bottle. The resulting wastewater flows downwards into the guide tray 2, then flows along the slope of the drain outlet 21 and is collected in the lower drawer 22. After collection, the drawer 22 is removed from the test box 1, the collected wastewater is poured out, and then the drawer 22 is inserted back into the test box 1. At this point, the silicone pad 23 on top of the drawer 22 contacts the test box 1, and friction secures the drawer 22 within the test box 1. Reagent bottles, rinsing bottles, and other containers are placed in the areas separated by the partition 31 within the storage box 3. When rinsing the slide, the fixing plate 14 can be rotated to an inclined state. This can be achieved by pulling the sliding sleeve outwards. 41 and compress the spring 42. At this time, a set of slots 43 are engaged in the horizontal limiting strip 44. Then, rotate the sliding sleeve 41 to drive the rotating shaft 4 and the fixed plate 14 to rotate. When the fixed plate 14 contacts the inclined positioning plate 47, the horizontal limiting strip 44 and the inclined limiting strip 45 are aligned. At this time, release the sliding sleeve 41 and, under the rebound of the spring 42, move the sliding sleeve 41 to one side of the fixed plate 14, and let a set of slots 43 be engaged in the inclined limiting strip 45, thus fixing the sliding sleeve 41, the rotating shaft 4, and the fixed plate 14. After rinsing, pull the sliding sleeve 41 again and compress the spring 42 to disengage the set of slots 43 from the inclined limiting strip 45. Then, reverse the sliding sleeve 41 to drive the rotating shaft 4 and the fixed plate 14 to reverse. When the fixed plate 14 contacts the inclined positioning plate 47, the horizontal limiting strip 44 and the inclined limiting strip 45 are aligned. When the fixed plate 14 is in contact with the horizontal positioning plate 46, it is in a horizontal state. Then, the sliding sleeve 41 is released and driven to move towards the fixed plate 14 under the action of the spring 42, and another set of slots 43 is locked in the inclined limit strip 45, so that the position of the sliding sleeve 41 and the fixed plate 14 can be fixed. When the fixed plate 14 slides on the guide rail 12, the first magnet 5 and the second magnet 51 are attracted to each other. When the fixed plate 14 contacts the baffle 13, the first magnet 5 and the second magnet 51 are attracted together, which can fix the position of the fixed plate 14. When rinsing the glass slide, some of the sewage generated will fall from the drain hole 6. When the operator rotates the sliding sleeve 41, his / her hand will come into contact with the silicone sleeve 7.
