Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Example:

[0028] Please refer to the following: Figure 1-5 ,

[0029] A novel test tube rack includes a placement plate 1 and a vertically placed partition 2, rollers 4 for rotating and placing test tubes, and multiple rotating shafts 3 for support.

[0030] Two partitions 2 are integrally formed on the top of the placement plate 1, and multiple rotating shafts 3 are rotatably arranged inside the two partitions 2. The multiple rotating shafts 3 are fixed to the roller 4 in pairs.

[0031] Multiple turntables 6 for rotation and multiple limiting rotating plates 5;

[0032] Multiple turntables 6 are fixedly connected to the left ends of multiple left-side rotating shafts 3, and multiple rotating plates 5 are fixedly connected to the right ends of right-side rotating shafts 3.

[0033] Multiple limiting grooves 7, and four limiting grooves 7 are provided on the outer wall of multiple rotating plates 5, and the edges of the multiple limiting grooves 7 are arranged in an arc shape;

[0034] Multiple damping structures, including a U-shaped frame 8, a spring 9, and a limiting rod 17;

[0035] Multiple placement holes 15 and multiple placement holes 2 16;

[0036] Multiple placement holes 15 and multiple placement holes 2 16 are provided on the inner side of multiple rollers 4, and the diameter of the multiple placement holes 15 is larger than the diameter of the placement holes 2 16.

[0037] Specifically, in actual use, when it is necessary to place test tubes, the test tubes are directly passed through the placement hole 15 or placement hole 16 and then contact the groove 11 inside the pad 10 to fix the test tubes. When it is necessary to place test tubes of different diameters and sizes, the turntable 6 is rotated, which will drive the rotating shaft 3 to rotate. The rotating shaft 3 will drive the roller 4 to rotate. After the rotating shaft 3 rotates 90 degrees, the placement holes 15 and 16 on the rotating roller 4 can change their positions, so that the roller 4 can place test tubes of different sizes to achieve the effect of placing test tubes of different sizes.

[0038] When it is necessary to clean the pad 10, move the handle 12. The handle 12 will drive the pad 10 to move, the magnet plate 13 on the pad 10 will move away from the iron plate 14, and then the pad 10 will move out of the interior of the placement plate 1, so as to remove the pad 10. This can make it easier to clean the pad 10 and the groove 11.

[0039] In the embodiment: multiple U-shaped frames 8 are fixedly welded to the top outer wall of the placement plate 1, and multiple springs 9 are fixedly installed on the outer wall of the placement plate 1. Limiting rods 17 are fixedly installed on the side of the multiple springs 9 away from the placement plate 1.

[0040] Specifically, multiple U-shaped frames 8 are provided on the placement plate 1, and multiple springs 9 are fixedly installed on the outer wall of the placement plate 1. The springs 9 are connected to the limiting rod 17, which can support the movement of the limiting rod 17 and achieve the effect of fixing the rotating plate 5.

[0041] In the embodiment: the outer walls of the multiple limiting rods 17 are slidably connected to the interior of the multiple U-shaped frames 8 respectively, the top ends of the multiple limiting rods 17 are arranged in an arc shape, and the multiple limiting rods 17 are inserted into the interior of the multiple limiting grooves 7.

[0042] Specifically, the limiting rod 17 is slidably connected to the U-shaped frame 8, which can limit the movement direction of the limiting rod 17. The top of the limiting rod 17 is arc-shaped, which can facilitate the limiting rod 17 to extend into the limiting groove 7 to limit the rotation of the rotating plate 5.

[0043] In the embodiment: a pad 10 is slidably connected to the inner side of the placement plate 1, a plurality of grooves 11 are provided on the top of the pad 10, a handle 12 is fixedly installed on the outer wall of the pad 10, a magnet plate 13 is fixedly installed on the side of the pad 10 away from the handle 12, and an iron sheet 14 is fixedly installed on the outer side of the placement plate 1.

[0044] Specifically, a pad 10 is slidably connected to the inner side of the placement plate 1 to support and fix the test tube. The groove 11 on the pad 10 is used to assist in fixing the bottom of the test tube. The handle 12 on the outer wall of the pad 10 is used to facilitate the removal of the pad 10. The magnetic plate 13 and the iron sheet 14 are attracted together to achieve the effect of temporarily fixing the pad 10.

[0045] In the embodiment: the side of the iron sheet 14 near the pad 10 is attracted and connected to the magnet plate 13, and the multiple placement holes 15 are respectively arranged in correspondence with the multiple grooves 11;

[0046] Specifically, the side of the iron sheet 14 closest to the pad 10 is attracted to the magnet plate 13, which can temporarily fix the pad 10 inside the placement plate 1, and make the placement hole 15 and the groove 11 correspond to each other to fix the bottom of the test tube.

[0047] Working principle: When test tubes need to be placed, they are directly passed through placement hole 15 or placement hole 16 to fix them in place. When test tubes of different diameters and sizes need to be placed, the rotating turntable 6 drives the rotating shaft 3 to rotate, which in turn drives the roller 4 to rotate. After the rotating shaft 3 rotates 90 degrees, the placement holes 15 and 16 on the rotating roller 4 can change their positions, allowing the roller 4 to hold test tubes of different sizes. Compared with related technologies, the novel test tube holder provided by this utility model has the following beneficial effects: it can achieve the effect of placing test tubes of different sizes.

[0048] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
