[0032] Example

[0033] like Figure 1 As shown, the present invention provides a test tube rack for immunological testing, comprising a rack body 1 comprising two sets of symmetrically arranged side panels 11. Two sets of first clamping plates 12 are fixedly connected between the two sets of side panels 11. Both sets of first clamping plates 12 are provided with multiple sets of first placement holes 13 positioned in corresponding positions. Below the multiple sets of first clamping plates 12 is a set of second clamping plates 14, fixedly connected between the two sets of side panels 11. Multiple sets of second placement holes 15 are provided on the second clamping plates 14. The diameter of the first placement holes 13 is larger than the diameter of the second placement holes 15. When placed, test tubes pass through the bottom of the first placement holes 13 and are positioned within the second placement holes 15, ensuring stable test tube placement.

[0034] For further information, see Figure 2The placement rack also includes two sets of adsorption mechanisms 2 fixedly mounted on both sides of the placement rack body 1. The adsorption mechanism 2 includes a vacuum box 21 fixed to the side of the side plate 11 away from the first clamping plate 12. The vacuum box 21 is hollow and has three sets of suction cups 22 at the bottom. When the pressure in the vacuum box 21 decreases, the suction cups 22 are sucked onto the table surface, thereby fixing the position of the placement rack body 1. Two sets of suction cylinders 23 are fixedly connected to the top of the vacuum box 21. The suction cylinders 23 are connected to the inside of the vacuum box 21. A piston 24 is slidably connected to the suction cylinder 23. When the piston 24 slides upward, the pressure in the vacuum box 21 is reduced, thereby achieving adsorption and fixation of the suction cups 22. A pull rod 25 is fixedly connected to the top of the piston 24. The tops of the two sets of pull rods 25 are fixedly connected to a synchronization plate 26. When the synchronization plate 26 moves upward, it drives the piston 24 to move synchronously through the pull rod 25.

[0035] Furthermore, Figure 3 As shown, the placement rack includes a negative pressure generating mechanism 3 disposed above the adsorption mechanism 2. The negative pressure generating mechanism 3 is used to adsorb the suction cup 22 onto the table surface. The negative pressure generating mechanism 3 includes a connecting plate 31 fixedly connected to the top of the synchronization plate 26. When the connecting plate 31 moves, the synchronization plate 26 is driven to move synchronously. A fixing rod 32 is fixedly connected to the side of the connecting plate 31 near the side plate 11. When the fixing rod 32 moves, the connecting plate 31 moves synchronously. The end of the fixing rod 32 away from the connecting plate 31 is fixedly connected to a limit plate 33. Limit blocks 34 are provided on both sides of the limit plate 33. The limit plate 33 is slidably connected between two sets of limit blocks 34. The limit blocks 34 are fixedly connected to the side of the side plate 11 away from the first clamping plate 12. The limit blocks 34 are L-shaped structures. The limit plate 33 slides smoothly under the limiting action of the limit blocks 34, thereby ensuring smooth movement of the limit plate 33. Two sets of positioning posts 35 are symmetrically arranged on either side of the connecting plate 31. These two sets of positioning posts 35 are fixedly connected to the side of the side plate 11 away from the first clamping plate 12, and the positioning posts 35 are fixed in position. A rotating plate 36 is rotatably connected to the positioning posts 35, and the rotating plate 36 rotates around the positioning posts 35. A sliding groove 37 is defined on the rotating plate 36, and the fixed rod 32 is slidably connected to the sliding groove 37. When the rotating plate 36 rotates, the fixed rod 32 slides in the sliding groove 37, simultaneously moving the fixed rod 32 up and down. A pressure plate 38 is mounted on the side of each set of rotating plates 36 away from the side plate 11, so that pressing down on the pressure plate 38 can cause the rotating plates 36 to deflect.

[0036] Specifically, the placement rack includes a limiting assembly 4 installed on the side of the placement rack body 1, and the limiting assembly 4 is used to maintain the adsorption state of the suction cup 22. The limiting assembly 4 includes two groups of fixed plates 41 fixedly connected to the side of the side plate 11 away from the first clamping plate 12. The fixed plates 41 are arranged in the shape of a regular quadrangular prism. The two groups of fixed plates 41 are slidably connected to limiting columns 42. The limiting columns 42 move smoothly under the limiting action of the fixed plates 41. The end of the limiting column 42 close to the connecting plate 31 is inclined, and the side of the connecting plate 31 close to the limiting column 42 is provided with an oblique groove 43. After the connecting plate 31 moves upward, one end of the limiting column 42 is stuck in the oblique groove 43 to prevent the connecting plate 31 from falling, thereby ensuring the negative pressure state in the vacuum box 21 and ensuring the stable adsorption of the suction cup 22. A limit ring 44 is provided between the two sets of fixed plates 41. The limit ring 44 is fixedly connected to the outer ring of the limit post 42. A first spring 45 is provided between the two sets of fixed plates 41. The first spring 45 is mounted on the side of the limit ring 44 away from the connecting plate 31 and is sleeved on the outer ring of the limit post 42. The first spring 45 is used to release the elastic force to drive the limit post 42 to snap into the inclined groove 43. A reset plate 46 is fixedly connected to the end of the limit post 42 away from the connecting plate 31 to facilitate the synchronous movement of the limit post 42, so that when the reset plate 46 is pushed, the limit post 42 is moved away from the connecting plate 31.

[0037] Finally, the placement rack includes a pressure relief assembly 5 mounted on the negative pressure generating mechanism 3. The pressure relief assembly 5 is used to reset the suction cup 22. The pressure relief assembly 5 includes a mounting plate 51 fixedly connected to the top of the connecting plate 31, which is used to increase the contact area of the second spring 54. A shaft 52 is fixedly connected to the top of the mounting plate 51, and the shaft 52 moves synchronously with the connecting plate 31. A positioning block 53 is slidably connected to the shaft 52. The positioning block 53 is fixedly connected to the side of the side plate 11 away from the first clamping plate 12. A second spring 54 is provided between the mounting plate 51 and the positioning block 53. The second spring 54 is used to release the elastic force to move the connecting plate 31 downward, facilitating the movement of the placement rack body 1 after the suction cup 22 is released. The second spring 54 is sleeved on the outer ring of the shaft 52. A limit plate 55 is fixedly connected to the top of the shaft 52 for limiting the position to prevent the connecting plate 31 from being too low, causing the chute 43 to be too far away from the limit post 42, thereby causing excessive negative pressure in the vacuum box 21.

[0038] In this embodiment, when in use, the placement rack body 1 is placed on a table, with both hands placed on either side of the placement rack body 1, while simultaneously pressing downward on the four sets of pressure plates 38. The pressure plates 38 then cause the rotating plate 36 to deflect, while the rotating plate 36 simultaneously causes the fixed rod 32 to move upward, and the fixed rod 32 slides within the slide slot 37. The connecting plate 31 then simultaneously moves upward, compressing the second spring 54. As the connecting plate 31 moves upward, the chute 43 moves to the position of the retaining post 42. The first spring 45 releases its elastic force, causing the retaining post 42 to become lodged within the chute 43, thereby preventing the connecting plate 31 from falling downward. As the connecting plate 31 moves upward, the piston 24 is driven upward within the suction cylinder 23 via the synchronizing plate 26 and the pull rod 25, thereby reducing the pressure within the vacuum chamber 21. The suction cup 22 then contacts the table surface and adheres to it, securing the placement rack body 1 to the table surface. When the test tube operation is completed during the inspection process and the placement rack body 1 needs to be moved, the reset plate 46 is moved so that the reset plate 46 drives the limit column 42 away from the connecting plate 31, so that the second spring 54 releases the elastic force to drive the connecting plate 31 to move downward, thereby increasing the pressure in the vacuum box 21 and the suction cup 22 is no longer adsorbed on the table, making it easier to pick up the placement rack body 1.

[0039] The above specific embodiment is only an optional embodiment of the present invention. Based on the technical solution of the present invention and the relevant inspiration of the above embodiment, those skilled in the art can make various alternative improvements and combinations to the above specific embodiment.
