Description

Technical Field

[0001] The utility model belongs to the field of sampling tubes, and in particular relates to a sampling tube. Background Art

[0002] A set of sampling and transport centrifuge tubes for sampling viruses such as influenza virus and hand, foot and mouth virus among microbial sampling and transport tubes, also known as specimen transport tubes, has now become a commercial product.

[0003] When the sampling tube is in use, it is placed directly in the bottle after sampling. Since the sampling rod is long, when the sampling tube vibrates greatly, the end of the sampling rod swings more widely, which makes it easier to throw out the test solution, or the sampling head contacts the bottle wall, causing the test solution to be contaminated, thereby resulting in inaccurate testing. Utility Model Content

[0004] The utility model aims at the deficiencies of the prior art and provides a sampling tube.

[0005] In order to achieve the above-mentioned purpose, the utility model provides the following technical solution: a sampling tube, comprising a bottle body, characterized in that: a bottle cap is detachably mounted on the bottle body, and a stabilizing component is mounted in the bottle cap;

[0006] The stabilizing component includes an outer cover screwed on the bottle body, a rotating shaft is rotatably connected at the center of the outer cover, a sampling rod is fixed to one side of the rotating shaft, a threaded groove is provided on the outer circumference of the sampling rod, a stabilizing block is sleeved on the outer circumference of the sampling rod, and the stabilizing block cooperates with the threaded groove.

[0007] Optionally, the top of the bottle body is provided with an external thread to cooperate with the outer cover, the interior of the bottle body is hollow, and at least two slide rails are provided on the inner wall of the bottle body.

[0008] Optionally, a plurality of anti-slip grooves are provided on the outer circumference of the outer cover, and an auxiliary cover is fixed to the side of the rotating shaft away from the sampling rod. The auxiliary cover is above the outer cover and has a diameter smaller than that of the outer cover.

[0009] Optionally, a sampling head is provided on a side of the sampling rod away from the rotating shaft, and at least two notches are provided on an outer peripheral side of the stabilizing block, and the notches cooperate with the slide rail.

[0010] Optionally, there is damping between the rotating shaft and the outer cover.

[0011] In summary, compared with the prior art, the present invention has the following beneficial effects:

[0012] 1. Due to the setting of the stabilizing component, the stabilizing block can be moved close to the sampling head by rotating the sampling rod to prevent the sampling rod from causing a large swing of the sampling head due to a large vibration, thereby causing the sampled test solution to be thrown onto the bottle wall, or the sampling head to contact the bottle wall due to a large swing amplitude, causing the test solution to be contaminated.

[0016] In order to enable those skilled in the art to better understand the solution of the present invention, the technical solution in the embodiment of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiment of the present invention.

[0017] As shown in Figure 1-2, a sampling tube includes a bottle body 10, on which a bottle cap is detachably installed, and a stabilizing component is installed in the bottle cap, and the stabilizing component includes an outer cover 11 screwed on the bottle body 10, and a rotating shaft 13 is rotatably connected at the center of the outer cover 11, and there is damping between the rotating shaft 13 and the outer cover 11 to prevent the auxiliary cover 12 from rotating at will, and a sampling rod 14 is fixed on one side of the rotating shaft 13, and a threaded groove is provided on the outer peripheral side of the sampling rod 14, and a stabilizing block 16 is sleeved on the outer peripheral side of the sampling rod 14, and the stabilizing block 16 cooperates with the threaded groove, and a plurality of anti-slip grooves are provided on the outer peripheral side of the outer cover 11, and an auxiliary cover 12 is fixed on the side of the rotating shaft 13 away from the sampling rod 14, and the auxiliary cover 12 is above the outer cover 11, and its diameter is smaller than the diameter of the outer cover 11.

[0018] The top of the bottle body 10 is provided with an external thread, which cooperates with the outer cover 11. The interior of the bottle body 10 is hollow, and at least two slide rails 17 are provided on the inner wall of the bottle body 10. A sampling head 15 is provided on the side of the sampling rod 14 away from the rotating axis 13. At least two notches are provided on the outer peripheral side of the stabilizing block 16, and the notches cooperate with the slide rails 17.

[0019] During use, after sampling is completed using the sampling rod 14 and the sampling head 15, the outer cover 11 can be screwed on, and then the auxiliary cover 12 is screwed to drive the sampling rod 14 to rotate through the rotating shaft 13, so that the stabilizing block 16 moves to the side away from the outer cover 11 until the stabilizing block 16 approaches the sampling head 15. The stabilizing block 16 can be fixed to prevent large vibrations from causing the sampling rod 14 to drive the sampling head 15 to swing greatly, thereby causing the sampled test solution to be thrown onto the bottle wall, or the sampling head 15 to contact the bottle wall due to the large swing amplitude, causing the test solution to be contaminated.

[0020] Obviously, the described embodiments are only a part of the embodiments of the utility model, not all of them. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the utility model.
