[0021] The following detailed, non-limiting description of the present invention, in conjunction with preferred embodiments and accompanying drawings, is provided. Obviously, the described embodiments are merely some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0022] Please see Figures 1-7 The present invention provides a technical solution: an adjustable rotating test tube rack, including a base 1, a support rod 2 fixedly connected to the top of the base 1, three sets of top plates 3 fixedly connected to the outer surface of the top of the support rod 2, a connecting sleeve 4 slidably connected to the outside of the support rod 2, three sets of first support plates 5 fixedly connected to the outside of the connecting sleeve 4, a first test tube groove 6 opened inside each of the three sets of first support plates 5, a cavity 7 opened inside the support rod 2, a rotating shaft 8 connected to the cavity 7 through a bearing, a gear 9 fixedly connected to the outer surface of the rotating shaft 8 inside the cavity 7, and a gear ring 10 fixedly connected to the inner wall of the connecting sleeve 4, the gear ring 10 meshing with the gear 9;

[0023] When the first support plate 5 is needed, the rotating shaft 8 is turned manually. The rotating shaft 8 can drive the gear 9 fixedly connected to the outside to rotate. The gear ring 10, which meshes with the gear 9, drives the connecting sleeve 4 to rotate synchronously, so that the first support plate 5 can be rotated to a suitable position for easy placement of test tubes.

[0024] When the test tube rack needs to be stored, rotate the shaft 8 again so that the shaft 8 can drive the externally fixed gear 9 to rotate. The gear ring 10, which meshes with the gear 9, drives the connecting sleeve 4 to rotate synchronously, so that the first support plate 5 rotates to the bottom of the top plate 3, and the first support plate 5 can be stored.

[0025] A limiting groove 11 is formed on the outer surface of the support rod 2, and a limiting block 12 is slidably connected inside the limiting groove 11. The limiting block 12 is fixedly connected to the inside of the connecting sleeve 4.

[0026] When the connecting sleeve 4 rotates, the limiting block 12, which is fixedly connected to the inner wall of the connecting sleeve 4, can move along the limiting groove 11 to ensure that the connecting sleeve 4 is more stable when rotating.

[0027] A mounting plate 23 is fixedly connected to the top of the rotating shaft 8. A locking rod 14 is slidably connected inside the mounting plate 23. A locking groove 13 is opened on the top of the support rod 2, and the locking rod 14 is slidably connected to the locking groove 13.

[0028] When the rotating shaft 8 needs to rotate, pull the locking rod 14 upward to separate the locking rod 14 from the locking groove 13, so that the rotating shaft 8 can rotate. When the rotating shaft 8 rotates to the appropriate position, the locking rod 14 is slidably connected to the mounting plate 23, and the bottom of the locking rod 14 is slidably connected to the locking groove 13, thereby fixing the position of the rotating shaft 8 and preventing the rotating shaft 8 from rotating on its own.

[0029] Each of the three sets of first support plates 5 has a sliding groove 15 inside. A second support plate 16 is slidably connected inside the sliding groove 15. A second test tube groove 17 is opened inside the second support plate 16. A fixing groove 18 is opened on the side of the second support plate 16 near the sliding groove 15. A rotating rod 19 is rotatably connected inside the fixing groove 18. A connecting plate 20 is fixedly connected to the end of the rotating rod 19 away from the fixing groove 18. A torsion spring 21 is fixedly connected between the connecting plate 20 and the fixing groove 18. A positioning groove 22 is opened at the bottom of the second support plate 16.

[0030] When the first test tube slot 6 in the first support plate 5 cannot hold the extra test tubes, the connecting plate 20 is rotated. The connecting plate 20 drives the torsion spring 21 to rotate, causing the connecting plate 20 to separate from the second support plate 16. The second support plate 16 is pulled, causing it to move along the slide groove 15. When the second support plate 16 moves to a certain position, the elastic force of the torsion spring 21 can drive the connecting plate 20 to reset, so that the connecting plate 20 is engaged with the positioning groove 22, which can fix the connecting plate 20. The remaining test tubes can be placed in the second test tube slot 17 in the second support plate 16.

[0031] Working principle: When the first support plate 5 needs to be used or its position adjusted, the rotating shaft 8 is rotated manually. The rotation of the rotating shaft 8 will drive the externally fixed gear 9 to rotate. Since the gear 9 is meshed with the gear ring 10, the gear ring 10 will drive the connecting sleeve 4 to rotate synchronously. When the connecting sleeve 4 rotates, the limiting block 12, which is fixedly connected to the inner wall of the connecting sleeve 4, will move along the limiting groove 11 to ensure that the connecting sleeve 4 is more stable when rotating, so that the first support plate 5 can be rotated to a suitable position. After the rotation is completed, the locking rod 14 can be inserted into the locking groove 13 to fix the position of the rotating shaft 8 and prevent the first support plate 5 from rotating arbitrarily. When the first test tube groove 6 in the first support plate 5 cannot hold extra test tubes, the connecting plate 20 is rotated. The connecting plate 20 drives the torsion spring 21 to rotate, so that the connecting plate 20 is separated from the second support plate 16. At this point, pull the second support plate 16, and the second support plate 16 will move along the slide groove 15 until the second support plate 16 is fully unfolded. The second test tube groove 17 inside can then be used to place the remaining test tubes. When the second support plate 16 is no longer needed, push the second support plate 16 back into the slide groove 15, release the connecting plate 20, and the elastic force of the torsion spring 21 will cause the connecting plate 20 to return to the state of being in contact with the second support plate 16, thus completing the storage.
