[0025] Example 1

[0026] See also Figures 1 to 4 The utility model provides a cell culture test tube placement tray, comprising a bottom plate 1, four corners of the upper surface of the bottom plate 1 are respectively fixed with a vertical rod 2, and a placement plate 3 is fixedly arranged on the vertical rod 2;

[0027] A plurality of through-going receiving holes 4 are provided on the plate body of the placing plate 3, and a plurality of groups of clamps 5 are provided on the lower surface of the placing plate 3, and each clamp 5 corresponds to one of the receiving holes 4;

[0028] A plurality of limiting holes 6 are formed on the body of the bottom plate 1 , and each limiting hole 6 is coaxial with one of the accommodating holes 4 .

[0029] Each set of clamps 5 includes a mounting plate 7 fixedly mounted on the placement plate 3, and a through hole is formed in the middle of the mounting plate 7, and the through hole corresponds to the receiving hole 4;

[0030] Two clamping arms 8 are rotatably arranged on the plate body of the mounting plate 7, and the two clamping arms 8 are symmetrically arranged on both sides of the through hole.

[0031] A transfer rod 9 is fixedly disposed on one side of each clamping arm 8 , and movable ends of the two transfer rods 9 are connected by a connecting rod 10 .

[0032] One of the transfer rods 9 faces the mounting plate 7, and the other transfer rod 9 faces away from the mounting plate 7. The two transfer rods 9 are parallel. Under the action of the transfer rod 9 and the connecting rod 10, the two clamping arms 8 can clamp and release the test tube. Under the action of the clamping arms 8, the test tube can be placed coaxially with the accommodating hole 4. At the same time, the clamping arms 8 can adapt to test tubes of different thicknesses, so that when the device is in use, it can be compatible with test tubes of various specifications and sizes, so that the device has universal performance and there is no need to set special tools according to test tubes of different sizes.

[0033] A clamping groove 11 is respectively formed at the movable end of each clamping arm 8 , and the two clamping grooves 11 are arranged opposite to each other.

[0034] The clamping groove 11 can increase the contact area between the clamping arm 8 and the test tube. At the same time, under the action of the clamping groove 11, the test tube and the accommodating hole 4 can be placed coaxially, thereby improving the stability of the test tube when placed.

[0035] A torsion spring is provided at the connection between one of the clamping arms 8 and the mounting plate 7 .

[0036] The torsion spring can ensure that the clamp arm 8 always maintains a clamping state, can adapt to test tubes of different thicknesses, and improve the versatility of the device when used.

[0037] A plurality of straight rods 12 are slidably arranged on the lower surface of the placement plate 3, and the two ends of the straight rods 12 are fixedly connected by fixing rods 13;

[0038] Furthermore, a spring is provided between one of the fixing rods 13 and the placement plate 3, and the spring can keep the straight rod 12 in a reset state when not in use, and will not affect the use of the holder;

[0039] Each straight rod 12 is located on one side of a row of clamps 5;

[0040] A plurality of protrusions 14 are fixedly disposed on each straight rod 12. Each protrusion 14 corresponds to one group of clamps 5. The protrusion 14 corresponds to an upward transfer rod 9. When the straight rod 12 moves horizontally, the protrusion 14 can push one of the transfer rods 9 to rotate.

[0041] When the utility model is used, when the user needs to take the test tube, the user can push the fixed rod 13 on the left side of the device, and the fixed rod 13 drives the straight rod 12 to move horizontally. When the straight rod 12 moves, the cam on the straight rod 12 can push the transfer rod 9 to rotate a certain angle. When the transfer rod 9 rotates, it drives the two clamping arms 8 to rotate respectively, so that the clamping arms 8 can loosen the test tube, which is convenient for the user to take the test tube;

[0042] When the user places the test tube, he only needs to insert the test tube into different accommodating holes 4. When the test tube moves downward, it collides with the two clamping arms 8 until the test tube is inserted into the limiting hole 6. Under the action of the two clamping arms 8, when the test tube is placed, the axis of the test tube and the axis of the accommodating hole 4 can be kept in an overlapping state, so that the test tube can be kept in a vertical placement state at all times to prevent the liquid in the test tube from pouring out.

[0043] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
