The design, consisting of a lower shell, upper shell, U-shaped plate, cylinder, and vertical rod, allows the cylinder to pull the U-shaped plate vertically downwards under the limit of the vertical rod during the staining process. This allows the upper shell to be fitted over the top outside of the lower shell, providing dust protection during staining. Furthermore, the drive motor, transmission rod, square-hole tube, electric rod, and lifting plate enable the drive motor to rotate the mesh cylinder, moving it to the through slot. This facilitates the removal of animal tissue sections from the mesh cylinder, reducing the contact area between the inside and outside of the staining machine and further improving dust protection. Additionally, the four mesh cylinders and staining cylinders allow for simultaneous staining of different types of animal tissue sections, as well as staining the same type of tissue sections with different colors, making the staining machine more versatile and practical.

[0012] 2. Through the arrangement of the mesh plate, T-shaped square post, first blind hole, first T-shaped rod, and second spring, after the animal tissue slice is placed into the inner cavity of the mesh tube, the cover plate is rotated to the top of the mesh tube. Then, the first T-shaped rod is pulled out of the inner cavity of the first blind hole, causing the T-shaped square post to drive the mesh plate to move vertically downward. This presses down on the animal tissue slice placed in the inner cavity of the mesh tube. When the mesh tube is immersed in the inner cavity of the staining tube, the animal tissue slice is completely immersed in the staining solution in the staining tube by pressing down on it. This allows for the injection of an appropriate amount of staining solution according to the staining needs, avoiding waste, and effectively ensuring the staining effect. Attached Figure Description

[0019] Please see Figures 1 to 5 The present invention provides the following technical solution:

[0020] An animal tissue section staining machine includes a base 1, a lower shell 2 fixedly connected to the top of the base 1, and an upper shell 3 sleeved on the outer side of the top of the lower shell 2. A U-shaped plate 4 is sleeved and fixedly attached to the outer wall of the upper shell 3.

The lifting plate 11 is equipped with a bearing, and the inner cavity of the bearing is rotatably connected to a square hole tube 12. The other end of each L-shaped rod 9 is fixedly connected to the outer wall of the square hole tube 12. The inner cavity of the square hole tube 12 is slidably penetrated by a matching transmission square rod 13. A drive motor 14 is provided at the top middle position of the upper housing 3, and the power end of the transmission square rod 13 is fixedly connected to the power output end of the drive motor 14. Each mesh cylinder 8 is equipped with a sealing mechanism at the top.

[0021] The sealing mechanism includes a cover plate 20, which is fitted onto the top of the mesh cylinder 8. A fixing post 21 is fixedly connected to the outside of the mesh cylinder 8, and a cylindrical cavity is formed on the fixing post 21. A round block 22 is rotatably connected to the inner cavity of the cylindrical cavity, and a square groove 24 is formed at the bottom of the round block 22. A through hole communicating with the inner cavity of the cylindrical cavity is formed at the center of the top of the fixing post 21. A connecting rod 23 is fixedly connected to the top of the cover plate 20, and the other end of the connecting rod 23 passes through the inner cavity of the through hole and is fixedly connected to the round block 22. A square cavity is formed near the bottom of the fixing post 21, and through holes are formed on both the upper and lower sides of the square cavity. A sliding connection is formed to the inner cavity of the square cavity. A matching limiting block 25 is provided, and a limiting square rod 26 is fixedly fixed through the limiting block 25. The top end of the limiting square rod 26 passes through the top perforated cavity and is inserted into the cavity of the square groove 24. The bottom end of the limiting square rod 26 passes through the bottom perforated cavity and is fixedly connected to a pull rod 27. A first spring 28 is sleeved on the outside of the limiting square rod 26, and the two ends of the first spring 28 are fixedly connected to the limiting block 25 and the bottom of the square cavity, respectively. When the staff puts the animal tissue slice into the cavity of the mesh tube 8, by rotating the cover plate 20 and bringing it close to the mesh tube 8, the cover plate 20 can be placed on the top of the mesh tube 8, thereby preventing the animal tissue slice from floating out of the mesh tube 8.

[0022] The bottom of the cover plate 20 has a circular groove 29, and the inner cavity of the circular groove 29 has a mesh plate 30 that is adapted to it. The top center of the cover plate 20 has a square hole, and the inner cavity of the square hole has a T-shaped square post 31 that is adapted to it. The bottom end of the T-shaped square post 31 is fixedly connected to the mesh plate 30. Several first blind holes 32 are equidistantly opened on the inner side of the T-shaped square post 31. The top of the cover plate 20 is fixedly connected to a fixing plate near the inner side, and a first T-shaped rod 33 slides through the fixing plate. The longest end of the first T-shaped rod 33 is inserted into the inner cavity of the adjacent first blind hole 32. A second spring 34 is sleeved on the outer wall of the first T-shaped rod 33, and the two ends of the second spring 34 are fixedly connected to the fixing plate and the first T-shaped rod 33 respectively. The mesh plate 30 is pressed down by the T-shaped square post 31 and the position of the animal tissue slice in the inner cavity of the mesh tube 8 is restricted, so that the animal tissue slice is completely immersed in the staining solution.

[0023] A through groove 15 is provided on the front side of the lower housing 2, and a sealing plate 16 is attached to the front side of the through groove 15. The sealing plate 16 and the lower housing 2 are slidably connected. A second T-shaped rod 17 is slidably passed through the sealing plate 16 near the bottom. A third spring 18 is sleeved on the outer wall of the second T-shaped rod 17, and the two ends of the third spring 18 are fixedly connected to the sealing plate 16 and the second T-shaped rod 17 respectively. A second blind hole 19 is provided on the front side of the lower housing 2, and the longest end of the second T-shaped rod 17 is inserted into the inner cavity of the second blind hole 19.

[0024] Limiting holes are provided near the four corners of the U-shaped plate 4, and vertical rods 6 that are adapted to it slide through the inner cavity of the limiting holes. The bottom end of each vertical rod 6 is fixedly connected to the base 1, which can vertically limit the upper shell 3 during the reciprocating lifting and lowering process, thereby improving the stability of the upper shell 3 in lifting and lowering movement.

[0025] Working Principle: In use, the following steps are taken: First, the cylinder 5 is activated to push the rotary plate 4 vertically upward, causing the upper housing 3 to detach from the top of the lower housing 2, thus opening the lower housing 2. The operator then injects the designated staining solution into the staining cylinder 7 and places the corresponding animal tissue slice into the mesh cylinder 8. The cover plate 20 is rotated and placed on top of the mesh cylinder 8. By inserting the top of the limiting square rod 26 into the inner cavity of the square groove 24, the round block 22 is locked, preventing the cover plate 20 from rotating. Furthermore, the height of the mesh plate 30 can be adjusted according to the staining solution level in the staining cylinder 7. By pulling the first T-shaped rod 33 out of the inner cavity of the first blind hole 32 and pushing the T-shaped square column 31 downward, the mesh plate 30 is moved downward, thus limiting the maximum floating height of the animal tissue slice in the mesh cylinder 8. Then, the cylinder 5 is activated to pull the upper housing 3 upward... After resetting, the electric lever 10 is activated to push the lifting plate 11 vertically downward, which in turn moves the square-hole tube 12 downward. The downward movement of the square-hole tube 12 can drive the mesh cylinder 8 downward through the L-shaped rod 9 and immerse it into the designated staining cylinder 7, thereby completely immersing the animal tissue slices in the staining solution. After staining is completed, the electric lever 10 can be activated to pull the lifting plate 11 upward to reset. Then, the second T-shaped rod 17 is pulled out of the inner cavity of the second blind hole 19, and the sealing plate 16 is pushed downward to open the through groove 15. The drive motor 14 is activated to drive the transmission square rod 13 to rotate. The rotation of the transmission square rod 13 drives the square-hole tube 12 to rotate, and the L-shaped rod 9 drives the mesh cylinder 8 to rotate to the through groove 15, thereby sequentially collecting the animal tissue slices from each mesh cylinder 8, reducing the contact area between the inside of the lower shell 2 and the outside world, and improving the dust prevention effect throughout the staining process.
