Description

Technical Field

[0001] This utility model relates to the field of water quality testing technology, and in particular to a sample storage device. Background Technology

[0002] Water is the source of life. Humans cannot live without water in their daily lives and production activities. The quality of drinking water is closely related to human health. Water quality testing uses storage devices to store water samples.

[0003] For example, Chinese utility model patent (CN215743541U) discloses a sample storage device for water quality testing, which states: "By setting a first movable block, a first movable hook and a scale bar, the first movable hook can be inserted into the first movable block first, so that the first movable hook and the first movable block can be installed together, so that the scale bar can be used normally, and it is convenient to observe the values ​​intuitively during subsequent testing."

[0004] However, the above-mentioned device lacks a cooling structure when used by staff. The water sample in the test tube will rise in temperature due to heat transfer from the hand, which will make the water sample prone to bacterial growth and affect water quality testing. Therefore, this application proposes a sample storage device. Utility Model Content

[0005] Based on this, it is necessary to provide a sample storage device to address the aforementioned technical problems. Through the overall structural design, the first cap can be easily screwed onto the upper end of the tube to seal the sample storage tank, thus facilitating the insertion of ice sticks into the low-temperature tank. The second cap is then placed on the top of the tube to seal the low-temperature tank, thereby cooling the inside of the tube. Combined with heat-insulating glass and heat-insulating cotton, the rate of heat exchange between the inside of the tube and the outside is reduced, making the cooling effect inside the tube more lasting.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0007] A sample storage device used for water quality testing;

[0008] The device includes a tube body, a low-temperature tank at the center of the tube body, a sample storage tank inside the tube body and outside the low-temperature tank, and multiple observation windows evenly distributed inside the tube body and outside the sample storage tank. Each observation window has an inner side fitted with heat-insulating glass, which is fixed to the tube body. A first cap is provided at the upper end of the tube body. A second external thread and a first external thread are respectively provided at the upper end of the tube body and outside the low-temperature tank and the sample storage tank. A first internal thread and a second internal thread are respectively provided on the inner side of the first cap. The first internal thread and the first external thread, and the second internal thread and the second external thread are threadedly connected. A second cap is also provided at the upper end of the tube body and above the first cap.

[0009] In a preferred embodiment of the sample storage device provided by this utility model, a first fastening ring is fixed on the outer side of the tube and at the lower end of the first external thread, and a second fastening ring is fixed on the inner side of the tube and at the lower end of the second external thread. The bottom end of the first cap is respectively attached to the first fastening ring and the second fastening ring.

[0010] In a preferred embodiment of the sample storage device provided by this utility model, the second cover is symmetrically threaded with hand-tightening bolts inside, and the ends of the two hand-tightening bolts that are close to each other extend into the tube body and are slidably connected to the tube body. The bottom end of the second cover is fitted with the first cover.

[0011] In a preferred embodiment of the sample storage device provided by this utility model, a sealing ring is fixed at the top of the tube and at the upper end of the two hand-tightening bolts. The hand-tightening bolts are located inside the second cover and fit against the second cover.

[0012] In a preferred embodiment of the sample storage device provided by this utility model, heat insulation cotton is fixed on the outside of the tube body and between every two heat insulation glasses.

[0013] In a preferred embodiment of the sample storage device provided by this utility model, a sampling seat is fixed inside the upper end of the first cover and between the first internal thread and the second internal thread. A sampling hole is opened at the center of the sampling seat. A rubber plug is provided on the upper end of the sampling seat. A rubber rope is fixedly connected between the outer side of the sampling seat and the outer side of the rubber plug.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] The sample storage device provided by this utility model, through its overall structural design, allows the first cap to be easily tightened onto the upper end of the tube body after water samples are poured into the sample storage tank. This is achieved by using the threaded connection between the first internal thread and the first external thread, and between the second internal thread and the second external thread, along with the support of the first and second fastening rings, thus sealing the sample storage tank. This facilitates the insertion of ice pops into the low-temperature tank. Then, the second cap is placed on the top of the tube body, which not only seals the low-temperature tank but also presses the first cap to make it more secure, thereby cooling the inside of the tube body.

[0016] The use of insulated glass and insulation cotton reduces the rate of heat exchange between the inside of the pipe and the outside, making the cooling effect inside the pipe more lasting. At the same time, the insulated glass and insulation cotton make it easier for staff to grip the pipe, effectively reducing heat transfer and further enhancing the insulation effect. This effectively inhibits bacterial growth and ensures the accuracy of water quality testing. Attached Figure Description
