[0004] To achieve the above purpose, this application provides a test tube rack for inspection, including a test tube rack structure. On both sides above the test tube rack structure, two sealing cylinders are connected. The two sealing cylinders are communicated with a limiting structure. A piston is arranged inside the sealing cylinder. A toothed plate is fixed to the bottom end of the piston. The bottom ends of the two toothed plates are fixed to the same connecting layer. Two suction cups are arranged below the connecting layer;

[0005] The toothed plate meshes with a gear. A rotating structure is connected to the gear. The two rotating structures are connected to a handle. The handle has two states through the rotating structure;

A plurality of test tube openings are provided on the top plate, and the test tube openings correspond to the tube supports.

[0010] As a further improvement of the above technical solution: a guide sleeve is fixedly connected to the support rod, and the toothed plate slides in the guide sleeve.

[0011] As a further improvement of the above technical solution: the limiting structure includes an air delivery pipe, both ends of the air delivery pipe are communicated with the upper part of the sealing cylinder respectively, and a plurality of air bags are also communicated with the ports of the air delivery pipe, and the air bags are correspondingly fixed at the test tube mouths.

[0028] Embodiment 1

[0029] As Figure 1-7 shown, a test tube rack is provided, which includes a test tube rack structure 2. The test tube rack structure 2 includes a bottom plate 21. Above the bottom plate 21, a plurality of tube supports 22 are fixedly connected. The bottom of the test tube can be supported by the tube supports 22, and the bottom of the test tube can also be limited. Above the bottom plate 21, four support rods 23 are also fixed. The tops of the four support rods 23 are fixed with a top plate 24. The support rods 23 connect the top plate 24 and the bottom plate 21, so as to increase the distance between the top plate 24 and the bottom plate 21 to meet the height for test tube storage. A plurality of test tube openings 25 are provided on the top plate 24, and the test tube openings 25 correspond to the tube supports 22. On both sides above the test tube rack structure 2, two sealing cylinders 1 are connected. The two sealing cylinders 1 are communicated with a limiting structure 3. The limiting structure 3 includes an air delivery pipe 32, which can be used to deliver air. The two ends of the air delivery pipe 32 are respectively communicated with the upper part of the sealing cylinder 1. A plurality of air bags 31 are also communicated with the ports of the air delivery pipe 32. The air bags 31 are correspondingly fixed in the test tube openings 25. Through the test tube openings 25, it is ensured that the test tube passes through and reaches the tube support 22. And due to the annular setting of the test tube openings 25, the air bags 31 are adapted to the test tube openings 25. Then, after the air bags 31 expand, they can enclose the outer periphery of the test tube. A piston 7 is provided inside the sealing cylinder 1. A toothed plate 11 is fixed to the bottom end of the piston 7. A guide sleeve 5 is fixedly connected to the support rod 23. The toothed plate 11 can be guided by the guide sleeve 5 to keep the toothed plate 11 moving smoothly up and down. The toothed plate 11 slides in the guide sleeve 5.

[0030] Among them, the air bag 31 is a continuous annular ring. The air bag 31 can be made of rubber and has an inflation space inside. The outer wall of the air bag 31 expands outward following the filling of the inflation space.

[0031] The toothed plate 11 meshes with the gear 8. A rotating structure 6 is connected to the gear 8. The two rotating structures 6 are connected to the handle 4. The handle 4 includes a connecting rod 41. Both ends of the connecting rod 41 are fixedly connected with connecting plates 42. Using the connecting rod 41 as the force application point facilitates operation. Moreover, when the two connecting rods 41 are combined, they can be held by hand to maintain force balance and facilitate the transfer of test tubes. The two connecting plates 42 are respectively fixed to the two rotating shafts 61. The rotating structure 6 includes a rotating shaft 61. The rotating shaft 61 is rotatably installed on the fixing plate 63 through a bearing 62. The rotating shaft 61 can rotate smoothly relying on the bearing 62, enabling the gear 8 to rotate smoothly and transmit power with the toothed plate 11. The fixing plate 63 is fixed to one side of the top plate 24. The gear 8 is fixed to the rotating shaft 61. A limiting sleeve 9 is fixed to one side of the fixing plate 63. Two elastic balls 10 are fixed to one end of the rotating shaft 61. Due to the elasticity of the elastic balls 10, when the rotating shaft 61 rotates, it can drive the elastic balls 10 to deform and break out of the limiting sleeve 9, and the elastic balls 10 can be snapped into the limiting sleeve 9 through the restoration of deformation, thereby locking the angle of the rotating shaft 61. One of the elastic balls 10 is engaged in the limiting sleeve 9, and the handle 4 has two states through the rotating structure 6;

[0032] When the handle 4 is turned upwards to the first placement state, the two handles 4 can be held together by hand, and the gear 8 meshes with the toothed plate 11 to control the upward movement of the piston 7, so that the piston 7 presses the gas into the limiting structure 3 to limit the test tube. The bottoms of the two toothed plates 11 are fixed with the same connecting layer 13. The connecting layer 13 can play a role in reinforcement and improve the stability of the bottom support. Two suction cups 12 are arranged below the connecting layer 13. By adsorbing on the desktop through the suction cups 12, the test tube rack can be fixed.

[0033] In this embodiment: By turning the handle 4 upwards, the handle 4 drives the gear 8 to transmit power with the toothed plate 11 through the rotating shaft 61, and the toothed plate 11 drives the piston 7 to move upwards. The piston 7 inputs the gas into the air bags 31 through the air pipes 32 respectively, and the inflation of the air bags 31 can play a role in positioning the test tube, thereby reducing the shaking of the test tube and improving the stability of the test tube.

[0034] Embodiment 2

[0035] On the basis of Embodiment 1, as Figure 4 shown, when the handle 4 is turned downwards to the second placement state, the gear 8 meshes with the toothed plate 11 and moves downwards, and the suction cups 12 can be smoothly pressed down to adsorb on the desktop.

[0036] In this embodiment: By turning the handle 4 downwards, the gear 8 meshes with the toothed plate 11 to drive the connection layer 13 to move downwards, and the gas inside the suction cups 12 is pressed out and adsorbed on the desktop, thereby positioning the test tube rack structure 2 and improving the stability of the test tube rack structure 2.

[0037] The working principle of the utility model is as follows: when moving the test tube, the handle 4 is flipped upward, the handle 4 drives the rotating shaft 61 to rotate, the rotating shaft 61 drives the gear 8 and the toothed plate 11 to transmit, so that the toothed plate 11 moves upward, the toothed plate 11 drives the suction cup 12 to leave the table through the connecting layer 13, and the toothed plate 11 pushes the piston 7 upward, so that the piston 7 presses the internal gas of the sealing tube 1 into the air bag 31 through the air delivery pipe 32, so that the air bag 31 expands and fits tightly against the periphery of the test tube, so that the test tube can be positioned, and at this time, the two handles 4 can be combined to perform hand-held transfer operations.

[0038] The above description is only a preferred embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present application should be included in the protection scope of the present application.
