[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. 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 protection scope of the present utility model.

[0022] like Figures 1 to 4 As shown, the present invention provides an ELISA plate cleaning device for laboratory testing, comprising a body 1; The top of the body 1 is provided with a tray 2, and a microporous plate 3 is placed inside the tray 2. The front side of the tray 2 is open. Hinges 4 are fixedly connected to both sides of the bottom of the tray 2. A sealing frame 5 is hinged to the side of the hinge 4 away from the tray 2. The back of the sealing frame 5 is attached to the front side of the tray 2 to form a top recessed platform for placing the microporous plate 3.

[0023] refer to Figure 2 A limiting plate 6 located at the bottom of the tray 2 is fixedly connected to the surface of the body 1. Guide rods 7 are fixedly connected to both ends of the limiting plate 6. A support plate 8 is slidably connected to the surface of the guide rods 7. The support plate 8 can slide on the surface of the guide rods 7 and squeeze the sealing frame 5 to flip and close when it is moved to the bottom of the sealing frame 5.

[0024] As a technical optimization of this utility model, the sliding support mechanism composed of the limiting plate 6, the guide rod 7 and the support plate 8 realizes the mechanical control of the opening and closing state of the sealing frame 5. When the support plate 8 slides along the guide rod 7 to the bottom of the sealing frame 5, it acts as a mechanical stop, pressing upward and fixing the sealing frame 5 to keep it in a reliable closed state.

[0025] refer to Figure 4 Both sides of the tray 2 are fixedly connected to connecting blocks 9 located on both sides of the sealing frame 5. A shaft 10 is inserted into the inner side of the connecting block 9. Movable blocks 11 are fixedly connected to both sides of the surface of the shaft 10. A cover plate 12 located on the top of the tray 2 is fixedly connected to the side of the movable block 11 away from the shaft 10.

[0026] As a technical optimization of this utility model, the top cover plate 12 opening and closing mechanism, which consists of connecting block 9, shaft 10, movable block 11 and cover plate 12, can cover the top of the tray 2 during cleaning, effectively preventing dust from contaminating the cleaned microporous plate 3 or preventing cleaning liquid aerosol from splashing out, thus improving the hygiene and safety performance of the device.

[0027] refer to Figure 4 Both sides of the shaft 10 are fixedly connected with spring plates 13, and both sides of the front of the support plate 8 are fixedly connected with brackets 14. A force-bearing rod 15 is fixedly connected to the side of the bracket 14 away from the support plate 8. The side of the spring plate 13 away from the shaft 10 extends to the back of the force-bearing rod 15 and contacts the force-bearing rod 15. The spring plate 13 can push the force-bearing rod 15 forward when it rotates with the shaft 10.

[0028] As a technical optimization of this utility model, by setting up a spring plate 13, the interaction between the spring plate 13, the pressure rod 16 and the force rod 15 is used to accurately convert the forward and backward linear motion of the support plate 8 into the forward and reverse rotational motion of the shaft 10, thereby controlling the opening and closing of the cover plate 12.

[0029] refer to Figure 4Both sides of the shaft 10 are fixedly connected to pressure rods 16 located inside the spring plate 13. The side of the pressure rod 16 away from the shaft 10 can squeeze the force rod 15 and make it move backward when the shaft 10 rotates.

[0030] As a technical optimization of this utility model, by setting up the pressure rod 16, the force of opening the cover plate 12 can be used to push the force rod 15 to move backward, further saving the operation steps of setting up additional drive equipment.

[0031] refer to Figure 4 Both sides of the front of the limiting plate 6 are provided with compression springs 17 sleeved on the surface of the guide rod 7. The side of the compression spring 17 away from the limiting plate 6 contacts the back of the support plate 8, and the compression spring 17 is elastic.

[0032] As a technical optimization of this utility model, by setting the compression spring 17, the support plate 8 can be supported, and the support plate 8 can have the effect of elastic reset.

[0033] The working principle and usage process of this utility model are as follows: After cleaning, the user pushes the support plate 8 backward, causing it to slide on the guide rod 7 and compress the compression spring 17. The support plate 8 moves backward so that it no longer supports the sealing frame 5 located on the front side of the tray 2. The sealing frame 5 then flips open forward and downward through the bottom hinge 4, exposing the loading and unloading port on the front side of the tray 2. At the same time, the support plate 8 moves backward, driving the force rod 15 to move through the bracket 14 on its front side. This interacts with the spring plate 13 and the pressure rod 16 fixed on the shaft 10, driving the shaft 10 to rotate. The movable block 11 drives the top cover 12 to open upwards. At this time, the top and front of the microporous plate 3 are unobstructed, and the user can easily take the plate directly from the front without tilting the entire tray 2, which greatly improves efficiency. After the new microporous plate 3 is placed in, the support plate 8 is pushed forward. Under the restoring force of the compression spring 17, the support plate 8 moves forward and first squeezes the sealing frame 5 to close it. Then, through the cooperation of the force rod 15 and the pressure rod 16, the drive shaft 10 is rotated in the opposite direction, so that the cover 12 is closed and the device returns to the closed state ready for cleaning.

[0034] In summary, this ELISA plate cleaning device transforms the front of the tray 2 from a traditional fixed and closed structure into a movable door structure through the sealing frame 5 hinged by the hinge 4. During cleaning, the sealing frame 5 closes, forming a sealed space with the tray 2 to ensure a stable cleaning process and prevent liquid splashing. When discharging, the sealing frame 5 can be flipped forward and downward to expose a pick-up and drop-off port.
