[0029] Embodiment 1:

[0030] Please refer specifically to Figure 1A high-performance double-sealed storage tube comprises: a tube body 1, a cover body 2, a middle ring 3 and a sampling rod 4. The tube body 1 is a hollow tube with one end open and the other end sealed; the cover body 2 is arranged at the open end of the tube body 1, and a first sealing member 21 is arranged on the inner top wall of the cover body 2. When the cover body 2 is completely covered on the tube body 1, the first sealing member 21 will contact and fit with the opening of the tube body 1, thereby sealing the tube body 1; the middle ring 3 is arranged inside the tube body 1, and the outer wall of the middle ring 3 is tightly fitted with the inner wall of the tube body 1 to form a seal, and a hollow tube 31 is arranged in the middle ring 3; one end of the sampling rod 4 is connected to the cover body 2, and the other end passes through the hollow tube 31 and is located in the tube body 1. Two second sealing members 41 are arranged on the outer wall of the sampling rod 4, and the second sealing members 41 are tightly fitted with the inner wall of the hollow tube 31 to form a seal.

[0031] The first sealing member 21 is a rubber sealing pad, which is adhered to the inner top wall of the cover body 2; the second sealing member 41 is a rubber sealing ring, which is sleeved on the outer wall of the sampling rod 4. The first sealing member 21 and the second sealing member 41 form a double sealing structure, that is, a sealing structure is set between the tube body 1 and the cover body 2, and between the middle ring 3 and the sampling rod 4, which greatly improves the sealing performance of the storage tube and can store samples for a long time.

[0032] Please refer to Figure 1 and 2 A connecting piece 22 is provided on the inner top wall of the cover body 2, and the connecting piece 22 is integrally injection-molded with the cover body 2. A connecting head 42 is provided at one end of the sampling rod 4, and the connecting head 42 is a cross structure. The connecting head 42 is snapped into the connecting piece 22 to form a tight fit, that is, the sampling rod 4 can be fixedly connected to the cover body 2 through this structure, and the sampling rod 4 can be taken and placed by disassembling the cover body 2.

[0033] Please refer to Figure 3 A plurality of convex ribs 23 are arranged on the outer wall of the cover body 2 at equal intervals and vertically distributed. The convex ribs 23 increase the friction between the hand and the cover body 2, making it easier for the user to open the cover body 2 for sampling.

[0034] Please refer to Figure 1 An external thread is provided on the outer wall of the tube body 1, and an internal thread is provided on the inner wall of the cover body 2. The internal thread on the cover body 2 is matched with the external thread on the tube body 1. The cover body 2 and the tube body 1 are connected together through the cooperation between the threads. The threaded connection has the advantages of easy installation, convenient disassembly, and simple operation.

[0035] Please refer to Figure 2 The sampling rod 4 is provided with a groove 43 surrounding the sampling rod 4 . The number of the grooves 43 is the same as the number of the second sealing members 41 , both of which are two. The second sealing members 41 are provided in the grooves 43 .

[0036] Please refer to Figure 1 and 3The outer shape of the tube body 1 is a structure that is small at the top and large at the bottom, and the inner cavity of the tube body 1 is a structure that is large at the top and small at the bottom. The design of the inner cavity that is large at the top and small at the bottom makes it easier for the middle ring 3 to be stuck in the inner cavity of the tube body 1.

[0037] Preferably, the tube body 1 is a transparent structure, and the tube body 1 is made of high-transparency general-grade polystyrene material, which ensures the convenience of observation.

[0038] Embodiment 2:

[0039] Please refer to Figure 1 and 2 This embodiment is a further improvement of the embodiment 1. A storage cover 5 is added on the basis of the embodiment 1. The storage cover 5 is arranged inside the tube body 1. A storage cavity 6 is formed between the storage cover 5 and the tube body 1. A desiccant is stored in the storage cavity 6. A plurality of small through holes 51 are opened on the storage cover 5. A step 11 is arranged inside the tube body 1. The storage cover 5 is arranged on the step, that is, the storage cover 5 is snapped on the step 11.

[0040] The desiccant can adsorb and dry the inside of the tube body 1, and the storage cover 5 separates the sampling rod 4 and the desiccant, adopting a contactless drying design, so that the sample can be stored for a long time.

[0041] The utility model is a high-performance double-sealed storage tube, and its working principle is explained in conjunction with the accompanying drawings:

[0042] When sampling is required, the sampling rod 4 is taken out from the tube body 1 by rotating the cover body 2, and the sampling rod 4 is used to sample. After sampling, the cover body 2 and the sampling rod 4 are reinstalled into the tube body 1. When the cover body 2 is assembled, the first sealing member 21 will contact and fit with the opening of the tube body 1 to form a seal, and the second sealing member 41 will fit closely with the inner wall of the hollow tube 31 to form a seal. The double seal and the desiccant can ensure the sealing and drying of the inside of the tube body 1, and the sample can be stored for a long time.

[0043] The above shows and describes the basic principle and main features of the utility model and the 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 for explaining the principle of 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 claimed by the utility model is defined by the attached claims and their equivalents.
