[0030] Preferably, in this embodiment, a transverse cover plate 10 is provided on the top of the box body 1, and a stabilizing device 11 is provided on the bottom left side of the transverse cover plate 10. The stabilizing device 11 includes a stabilizing block 111, a rotation control block 112, and a rotation positioning plate 113. The stabilizing block 111 is fixed on the bottom left side of the transverse cover plate 10, and the top of the rotation control block 112 is rotatably installed inside the box body 1. The rotation positioning plate 113 is fixed on the right side of the rotation control block 112, and the bottom right side of the stabilizing block 111 is located inside the rotation area of ​​the rotation positioning plate 113. The transverse cover plate 10 can be provided to protect the top of the test tube, and the stabilizing device 11 can improve the stability of the transverse cover plate 10 when the entire box body 1 shakes, so as to prevent the transverse cover plate 10 from detaching from the box body 1 and causing damage to the top of the test tube, and when the box body 1 is in a stable state, the transverse cover plate 10 can also be relatively easily pulled out.

[0031] Preferably, in this embodiment, the stabilizing block 111 is made of iron, and the left side of the stabilizing block 111 is magnetically connected to the auxiliary positioning magnetic block 12, and the positioning magnetic block 12 is fixed inside the box body 1. By providing the iron stabilizing block 111 and the auxiliary positioning magnetic block 12, the horizontal cover plate 10 can be auxiliaryly fixed to improve the stability of the horizontal cover plate 10, without manually fixing the position of the horizontal cover plate 10.

[0032] Preferably, in this embodiment, a buffer cavity 101 is provided on the left side of the transverse cover plate 10, an elastic buffer plate 102 is fixed to the inner wall of the buffer cavity 101, and the left side of the elastic buffer plate 102 is in conflict with the limit plate 103, and the limit plate 103 is fixed inside the box body 1. By providing the elastic buffer plate 102 and the limit plate 103, not only can the transverse cover plate 10 be prevented from colliding with the box body 1 when inserted into the box body 1 to generate a large noise, but also the collision force between the stabilizing block 111 and the positioning magnetic block 12 can be prevented from being too large, resulting in the demagnetization of the positioning magnetic block 12, thereby improving the service life of the positioning magnetic block 12.

[0033] Working principle: insert the test tube into the placement socket 31 and make the bottom of the test tube contact with the top of the placement pad 4. At this time, the test tube is located between the two clamping blocks 41, and the two soft squeezing blocks 412 will generate squeezing thrust on the side of the test tube. When the box 1 is transported by a vehicle, if the vehicle is traveling on a bumpy road, the speed of the vehicle and the box 1 will change, and the counterweight block 51 will shake under the action of inertia. At this time, the counterweight block 51 drives the push block 5 to rotate, and the push block 5 will squeeze the elastic sheet 411. The elastic sheet 411 is deformed and the center pushes the soft squeezing block 412 to move toward the test tube, thereby auxiliary clamping and fixing the side of the test tube. When the test tube needs to be taken out from the box 1, since the box 1 is in a stable state, the elastic sheet 411 is not subject to the squeezing thrust of the push block 5. At this time, the elastic squeezing force between the test tube and the soft squeezing block 412 is small, and it can be taken out manually more easily. When the box body 1 moves inside the car, the buffer device 6 on the side of the box body 1 will collide with the buffer device 6 in other boxes 1. At this time, the movable buffer block 62 will move toward the box body 1 and squeeze the buffer spring piece 63. The deformation of the buffer spring piece 63 will also drive the secondary buffer piece 631 to deform. At this time, the elastic force of the buffer spring piece 63 and the secondary buffer piece 631 can buffer the movement of the movable buffer block 62, thereby preventing the box body 1 from colliding with other boxes 1 and being damaged; the deformation of the buffer spring piece 63 will drive the drive plate 632 to move, and the two drive plates 632 are far away One end of the buffer spring 63 will move at the top and bottom of the matching plate 633 respectively, and the driving plate 632 will collide with multiple rubber blocks 634. The vibration generated by the collision will be transmitted to the movable buffer block 62 through the matching plate 633 and the secondary buffer sheet 631. Since the overall temperature of the box body 1 is relatively low, when the box body 1 is stored in an area with high humidity, a certain amount of water droplets will be generated on the surface of the movable buffer block 62. The vibration of the movable buffer block 62 will cause the water droplets on the surface of the movable buffer block 62 to drip. The dripping water droplets will fall to the top of the introduction plate 622, and move to the soft guide plate 9 through the introduction port 621 under the guiding action of the introduction plate 622. Under the guiding action of the soft guide plate 9, the water flow will enter the water storage device 7 through the water inlet groove 8 for storage. During the shaking process of the water storage device 7, the stored water in the water storage device 7 will splash and act on the bottom of the anti-backflow baffle 71, thereby preventing the stored water from splashing out. When taking out the test tube, it is necessary to first pull out the transverse cover plate 10 to the right, which can protect the top of the test tube. After putting in the test tube, push the transverse cover plate 10 to the left until the stabilizing block 111 is magnetically adsorbed with the positioning magnetic block 12. In this process, the limit plate 103 will contact the elastic buffer plate 102 and the elastic buffer plate 102 will deform. The elastic force of the elastic buffer plate 102 will slow down the transverse cover plate 10 to prevent the transverse cover plate 10 from moving too fast. When the vehicle and the box 1 accelerate suddenly, the transverse cover plate 10 The inertia of the cover plate 10 pulls the transverse cover plate 10 to the right, and at the same time, the inertia of the rotating control block 112 will also cause the rotating control block 112 to rotate counterclockwise. At this time, the rotating control block 112 drives the rotating positioning plate 113 to rotate so that the end point of the rotating positioning plate 113 contacts the right side of the stabilizing block 111. At this time, the blocking effect of the rotating positioning plate 113 on the stabilizing block 111 can produce a blocking effect on the transverse cover plate 10, so as to improve the stability of the transverse cover plate 10 and prevent the transverse cover plate 10 from moving out of the box body 1.

[0034] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
