[0027] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0028] Embodiment 1:

[0029] Please refer to Figures 1-5 , the present invention provides a technical solution: a culture medium test tube, including a test tube body 1 and a sealing structure 2, wherein the sealing structure 2 is installed at the upper end of the test tube body 1, an annular seat 11 is arranged at the end of the upper port of the test tube body 1, a baffle component 3 is arranged inside the test tube body 1, the sealing structure 2 includes a first pipe orifice 21, an outer ring 22, and a cover ring 23. The first pipe orifice 21 is fixed on the upper end surface of the annular seat 11. A plurality of limiting rings 211 are sequentially arranged on the outer wall of the first pipe orifice 21 from top to bottom. The outer ring 22 is detachably installed on the outer wall of the first pipe orifice 21. A connecting piece 24 is directly arranged between the outer wall of the upper port of the outer ring 22 and the cover ring 23. A cylindrical frame 231 is arranged at the center of the circle inside the cover ring 23. A detachable sealing plug 25 is arranged outside the cylindrical frame 231. A plurality of elastic cards 251 are evenly arranged in a ring at the lower end of the sealing plug 25. The annular elastic cards 251 clamp the sealing plug 25 outside the cylindrical frame 231.

[0030] Specifically, in this embodiment, by improving the sealing structure 2 of the existing test tube, the test tube can be opened with one hand, which is convenient for operation.

[0031] As Figure 3 shown: A plurality of outwards turned-up tooth pieces 221 are arranged at the upper port of the outer ring 22. The plurality of tooth pieces 221 surround the upper port of the outer ring 22 with the vertical center line of the outer ring 22 as the center of the circle. This design can connect the upper cover ring 23.

[0032] A plurality of tooth grooves 232 are evenly arranged in a ring on the conical surface of the upper port of the cover ring 23, and the tooth piece 221 can be stuck in the tooth groove 232. This design can stably clamp the cover ring 23.

[0033] As Figure 4 shown: An indented moving groove 233 is provided on the outer wall of the cover ring 23. By placing the thumb in the moving groove 233, the cover ring 23 can be opened.

[0034] As Figure 2 shown: The blocking component 3 includes a vertical plate 31 in the shape of a right triangle. A baffle 32 is provided on the left inclined surface of the vertical plate 31, and an arc plate 33 is provided on the upper end surface of the baffle 32. This design can conveniently observe whether the bacteria produce gas.

[0035] Each part of the blocking component 3 is integrally formed.

[0036] The specific working principle of this embodiment is as follows: When using this device, place the thumb in the moving groove 233 of the cover ring 23 and then move it outwards to open the cover ring 23 (as the cover ring 23 is opened, the tooth piece 221 of the outer ring 22 will disengage from the tooth groove 232 of the cover ring 23). After opening, inject the bacterial liquid into the test tube body 1;

[0037] After injecting the bacteria, observe the inside of the test tube body 1. When the bacteria produce gas, the gas will generate a hollow empty area at the space blocked by the baffle 32. By observing whether there is an empty area in this area, it can be determined whether the bacteria produce gas.

[0038] Embodiment 2:

[0039] Please refer to Figures 6-8 , the difference between this embodiment and Embodiment 1 is that: The sealing structure 2 includes a second pipe orifice 26 and a sealing cover 27. The sealing cover 27 can block the port of the second pipe orifice 26. An annular ring 261 is provided on the inner wall of the upper port of the second pipe orifice 26. A clamping ring 262 is provided on the upper end surface of the annular ring 261. A first ring groove 263 and a snap ring 264 are provided on the outer wall of the clamping ring 262. The snap ring 264 is located at the lower side position of the first ring groove 263. A rubber sealing ring 2631 is provided in the first ring groove 263. This design can stably connect the upper sealing cover 27.

[0040] A snap ring 271 is provided at the lower end of the sealing cover 27. Second annular grooves 272 and clamping grooves 273 are respectively provided on the inner wall of the snap ring 271. The clamping groove 273 is located below the second annular groove 272, and the clamping ring 264 can be clamped by the clamping groove 273. The design of the sealing cover 27 can firmly block the test tube body 1 and prevent leakage.

[0041] The inner wall of the lower port of the snap ring 271 is designed as a conical surface.

[0042] The specific working principle of this embodiment is as follows: Grasp the sealing cover 27 and pull it outwards (as the sealing cover 27 is pulled out, the snap ring 271 will deform slightly, the clamping ring 264 will disengage from the clamping groove 273, and the rubber sealing ring 2631 will also deform due to extrusion). After pulling out, the bacterial liquid can be filled. After filling, the sealing cover 27 can be inserted into the second pipe orifice 26. After insertion, the clamping ring 264 will be clamped in the clamping groove 273, and at the same time, the rubber sealing ring 2631 will also deform to improve the sealing performance and prevent the bacterial liquid from leaking.

[0043] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
