[0017] Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0018] Example: Please refer to Figs. 1-3A test tube for food testing includes a test tube body 1, a sealing stirring structure installed at the upper end of the test tube body 1, and a fixed support structure fitted at the lower end of the test tube body 1.

[0019] The sealed stirring structure includes: a sealing cover 2, a mounting plate 3, a sealing bearing 4, a stirring shaft 5, an annular chute 6, an annular slide rail 7, an operating cover 8, and a transmission assembly;

[0020] The sealing cap 2 is fitted onto the outer side of the upper end of the test tube body 1. The mounting plate 3 is fixedly installed inside the sealing cap 2. The sealing bearing 4 is embedded in the center of the mounting plate 3. The top end of the stirring shaft 5 moves through the sealing bearing 4. The annular groove 6 is installed on the upper end of the sealing cap 2. The annular slide rail 7 is fitted onto the outer side of the annular groove 6. The operating cover 8 is fixedly fitted onto the outer side of the annular slide rail 7. The transmission component is installed inside the operating cover 8 and connected to the top end of the stirring shaft 5.

[0021] When storing food test samples, staff first place the sample into the test tube body 1, then place the sealing cap 2 on top of the test tube body 1. The test tube body 1 is sealed by the mounting plate 3 and the sealing bearing 4, achieving the purpose of sealed storage of the sample. The test tube body 1 is then placed on the top of the fixed support structure for independent support, or it can be fixed by a test tube rack. When it is necessary to mix the sample in the test tube body 1, the staff turns the operating cap 8 on the top of the sealing cap 2. With the cooperation of the annular slide rail 7 and the annular slide groove 6, the operating cap 8 rotates on the top of the sealing cap 2, and cooperates with the transmission component to drive the stirring shaft 5 to rotate in the sealing bearing 4. The stirring shaft 5 thoroughly mixes the sample in the test tube body 1.

[0022] In the specific implementation process, the transmission components include: internal gear ring 9, bearing housing 10, mounting shaft 11, transmission gear 12, and stirring gear 13;

[0023] The internal gear ring 9 is fixedly installed on the inner wall of the operating cover 8, the bearing seat 10 is installed on the upper end of the mounting plate 3, the bottom end of the mounting shaft 11 is movably embedded in the bearing seat 10, the transmission gear 12 is fixedly installed on the upper end of the mounting shaft 11 and meshes with one side of the internal gear ring 9, and the stirring gear 13 is fixedly installed on the upper end of the stirring shaft 5 and meshes with the transmission gear 12.

[0024] When mixing the sample in the test tube body 1, the operating cover 8 rotates on the upper end of the sealing cover 2, and the internal gear ring 9 located in the operating cover 8 rotates accordingly. Under the meshing action of the internal gear ring 9 and the transmission gear 12 at the upper end of the mounting shaft 11, the transmission gear 12 and the mounting shaft 11 are driven to rotate in the bearing seat 10. Under the meshing action of the transmission gear 12 and the stirring gear 13, the stirring gear 13 and the stirring shaft 5 are driven to rotate. The number of teeth of the transmission gear 12 is greater than that of the stirring gear 13, so the rotation speed of the stirring gear 13 and the stirring shaft 5 can be effectively increased to ensure the mixing effect of the sample.

[0025] In the specific implementation process, the fixed support structure includes: support frame 14, mounting shell 15 and magnetic block 16;

[0026] The support frame 14 is movably mounted on the outer side of the lower end of the test tube body 1, the mounting shell 15 is fixedly mounted on the lower end of the support frame 14, and the magnetic block 16 is fixedly mounted on the inner wall of the mounting shell 15.

[0027] When the test tube body 1 is placed independently, the staff will embed the test tube body 1 into the support frame 14. The installation shell 15 cooperates with the support frame 14 to provide stable support for the test tube body 1. The magnetic block 16 inside the installation shell 15 can be used to attach and fix the installation shell 15 to the upper end of the metal table, further increasing the stability of the test tube body 1.

[0028] In the specific implementation process, the outer side of the operating cover 8 is machined with anti-slip protrusions 17.

[0029] In the specific implementation process, a magnetic label plate 18 is installed on the top of the operating cover 8.

[0030] The anti-slip protrusions 17 effectively increase the friction on the outside of the operating cover 8, ensuring the rotation effect of the operating cover 8. At the same time, the magnetic label plate 18 can mark the sample inside the test tube body 1 for easy retrieval by personnel.

[0031] 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.
