[0012] Preferably, the diameter of the plug is larger than the outer diameter of the largest annular sealing strip.

[0013] Compared with the prior art, the utility model has the following beneficial effects:

[0014] In the test tube bottle stopper assembly, the annular sealing strip design on the outer wall of the stopper not only enhances the friction between the stopper and the test tube mouth, ensuring good sealing, but also facilitates the installation and removal of the test tube stopper, reducing the risk of damage to the test tube stopper during operation. It is particularly worth mentioning that the test tube stopper part adopts a design of connecting multiple plugs with different diameters end to end. This gradual design further enhances the adaptability of the test tube stopper to different test tube calibers.

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] The utility model provides a test tube bottle stopper component, such as Figure 1-Figure 3 As shown, it includes a test tube 1, the end of the test tube 1 is installed with a large-sized sealing plug 2 or a small-sized sealing plug 3, the large-sized sealing plug 2 includes a plug head 21, the outer wall of the plug head 21 is installed with a plurality of annular convex strips 22, one end of the plug head 21 is installed with a test tube plug 23, the test tube plug 23 includes a plurality of plug rods 231 with different diameters, the plug rods 231 are connected end to end in order from large to small in diameter, and an annular sealing strip 232 is installed on the outer side of the end of each plug rod 231, and the outer diameter of the annular sealing strip 232 becomes smaller in sequence to adapt to the connection of different test tube mouth sizes.

[0022] In this embodiment, the large-sized sealing plug 2 has the same structure as the small-sized sealing plug 3. The diameter of the large-sized sealing plug 2 is larger than that of the small-sized sealing plug 3. The large-sized sealing plug 2 is convenient for connecting to the joint of the sorting machine. The small-sized sealing plug 3 does not need to be adapted to the sorting machine and can be used for manual sorting.

[0023] Specifically, a sorting machine interface 24 is provided at one end of the plug 21 away from the test tube plug 23, so as to facilitate connection with a connector of the sorting machine.

[0024] Furthermore, the annular convex strips 22 are arranged at equal intervals, a safety cap is arranged outside the plug 21, and the outer edge of the annular convex strips 22 fits with the inner wall of the safety cap to ensure sealing.

[0025] Furthermore, a reinforcing support plate 25 is installed on the outer side of the plug column 231 near one end of the plug head 21. The reinforcing support plates 25 are arranged in a circular shape with equal intervals on the outer wall of the plug column 231 to support one side of the plug head 21 and ensure the stability of the plug head 21.

[0026] Furthermore, an outer wall of the reinforcing support plate 25 away from the plug 231 is provided with an inclined edge.

[0027] Furthermore, the number of the annular sealing strips 232 is four or more, and is adapted to at least four or more test tubes 1 with different tube opening diameters.

[0028] Furthermore, the diameter of the plug 21 is larger than the outer diameter of the largest annular ridge 22 . This design ensures that the plug 21 can be firmly installed at the mouth of the test tube without causing installation difficulties or instability due to the excessively large diameter of the annular ridge 22 .

[0029] When the test tube bottle plug assembly of the utility model is used, firstly, a plug 21 of appropriate size (large-size sealing plug 2 or small-size sealing plug 3) is selected according to whether it is suitable for the needs of the sorting machine. Since the large-size sealing plug 2 and the small-size sealing plug 3 have the same structure but different diameters, the selection process is simple and flexible. Next, align the selected plug 21 with the mouth of the test tube and gently push it in. Since the outer wall of the plug 21 is provided with a plurality of annular ridges 22, these ridges increase the friction with the inner wall of the mouth of the test tube, so that the plug 21 can be firmly installed on the mouth of the test tube. At the same time, the diameter of the plug 21 is larger than the outer diameter of the largest annular ridge 22, which ensures the stability and sealing of the installation.

[0030] At the other end of the plug, the test tube plug 23 is adapted to the inner diameter of the test tube mouth through a plurality of plugs 231 of different diameters. These plugs 231 are connected end to end in descending order of diameter, and an annular sealing strip 232 is installed on the outer side of the end of each plug 231. This design enables the test tube plug 23 to fit tightly against the inner wall of the test tube mouth, and provides a good sealing effect regardless of how the diameter of the test tube mouth changes.

[0031] When the test tube plug needs to be removed, it can be removed by gently pulling it out. Due to the unique design of the plug head 21 and the test tube plug 23, the installation and removal process becomes simple and will not damage the test tube plug 23 or the test tube mouth.

[0032] In addition, a sorting machine interface 24 is provided at one end of the large-sized sealing plug 2 away from the test tube plug, so that the test tube bottle plug assembly can be used in conjunction with a sorting machine to achieve automated capping and sorting, greatly improving work efficiency.

[0033] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only preferred examples of the utility model and are not used to limit the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected. The scope of protection of the utility model is defined by the attached claims and their equivalents.
