Referring to fig. 1 to 3, a test tube holding device according to an embodiment of the present utility model includes: the device comprises a fixing frame 10, a clamping assembly 20 and a detection assembly 30, wherein a plurality of containing holes 11 are formed in the upper end of the fixing frame 10, and the containing holes 11 are sequentially arranged; the clamping assembly 20 is arranged at the upper end of the fixing frame 10, the clamping assembly 20 comprises a plurality of limiting blocks 21 and a plurality of sliding blocks 22, the limiting blocks 21 are fixedly arranged on the fixing frame 10, the sliding blocks 22 are slidably arranged on the fixing frame 10, profiling concave parts 23 are arranged on the limiting blocks 21 and the sliding blocks 22, the limiting blocks 21 and the sliding blocks 22 are oppositely arranged, and the profiling concave parts 23 define accommodating holes 11; the detecting assembly 30 is disposed in the fixing frame 10 below the accommodating hole 11, and the detecting assembly 30 is used for detecting whether a sample exists in the test tube.

Specifically, the sliding block 22 of the rear side keeps a certain distance from the fixed stopper 21 in the initial state, facilitating the insertion of the test tube. When the test tube is put down, the sliding block 22 slides forward, and the test tube is clamped in the profiling concave parts 23 of the two blocks in cooperation with the front limiting block 21. It will be appreciated that the test tube initially placed in the accommodating hole 11 cannot fall completely, so that the test tube is fixed at the position of the accommodating hole 11, the clamping assembly 20 can push the test tube into the accommodating hole 11 firstly through the sliding block 22 and the limiting block 21, then clamp the test tube in the accommodating hole 11, the cup separating device is convenient for opening the cover of the test tube, and after the test tube is moved to the position of the accommodating hole 11, the clamping assembly 20 can release the test tube, so that the detecting device below the accommodating hole 11 can detect whether a sample exists in the test tube, and the cup separating device is prevented from empty sampling.

Referring to fig. 1 to 3, in some embodiments of the present utility model, further, the clamping assembly 20 further includes a slidable pushing block 24, where the pushing block 24 slides on the fixing frame 10, and the sliding may be pushed by a cylinder or a screw drive, and may even be a rack and pinion drive, and the pushing form may not be limited. The pushing block 24 includes a plurality of limiting grooves 241, and each sliding block 22 is slidably disposed in each limiting groove 241, so that when the pushing block 24 is moved forward, each sliding block 22 can be pushed to move forward, so as to form a clamping action, and further, the test tube can be pushed to move and simultaneously be clamped by the limiting block 21.

Further, the pushing block 24 is connected with the sliding block 22 through an elastic member 25, the elastic member 25 may be a spring or an elastic rubber member, etc., the elastic member 25 is disposed between the pushing block 24 and the sliding block 22, one end of the elastic member 25 is connected to the bottom of the limiting slot 241, and the other end of the elastic member 25 is connected to the sliding block 22. It is conceivable that when the push block 24 is moved backwards, the slide block 22 can be pulled backwards by the elastic member 25, which releases the test tube and at the same time allows the insertion of the next batch of test tubes. In addition, the buffer action of the elastic piece 25 can also be utilized to reduce the impact of the sliding block 22 on the test tube and protect the test tube.

The pressure sensor 31 is provided in the mount 10; the tray 32 is disposed at the upper end of the pressure sensor 31, and the upper end surface of the tray 32 is flush with the upper end surface of the mount 10. When the clamping assembly 20 pushes the test tube into the position of the accommodating hole 11, namely above the tray 32, and then the clamping assembly 20 loosens the test tube, the weight of the test tube can be detected by the pressure sensor 31 at the lower end of the tray 32, and whether a sample exists in the test tube can be known by comparing the detected weight with the weight of an empty test tube. It should be noted that, the detecting component 30 may also be an optical detecting component 30, and an optical sensor is disposed at the bottom of the test tube to collect the color of the sample in the test tube, and also to infer whether the sample exists in the test tube.

In some embodiments of the present utility model, the shape of the tray 32 conforms to the shape of the receiving hole 11. The shape of the tray 32 is consistent with the shape of the accommodating hole 11, so that the tray 32 can be prevented from being subjected to uneven force of the test tube, and error detection can be prevented. Further, the contour of the profiling concave portion 23 is arc-shaped, so that the test tube can be clamped conveniently, and the accommodating hole 11 is a round hole, so that the tray 32 can be provided as a round hole.
