Description

Technical Field

[0001] This utility model relates to the field of drug detection and sampling technology, specifically a leak-proof drug detection sampling device. Background Technology

[0002] Hair testing in drug detection has advantages such as convenient sampling, long traceability, rapid and accurate testing, convenient storage and good stability, and wide applicability. These advantages make hair testing a promising application in the field of drug detection and of great practical value.

[0003] Patent document CN215115407U discloses a sampling device for drug detection. The device includes a support, a first blade, a second blade, and a first motor. A retention component is cylindrical and mounted on the support. One end of the retention component is open, and the other end is closed. The closed end has a through-hole that allows gas to pass through while blocking hair. The open end of the retention component faces the side of the second blade that is opposite to the first blade. The projection of the upper end of the second blade onto a first plane falls within the projection of the retention component onto the first plane, which is perpendicular to the central axis of the retention component. A gas delivery unit is mounted on the support and is used to extract gas from the retention component. This device offers advantages such as automated collection. However, this patent has the following problems in practical use:

[0004] This sampling device collects hair by setting a retention component on one side of an electric hair clipper. However, during use, hair residue can easily remain between the electric hair clipper and the retention component, causing hair mixing and affecting the sampling results. Furthermore, hair is prone to scattering during transfer and is difficult to seal immediately, leading to hair replacement. This makes the sampling device inconvenient to use and thus impractical for drug detection.

[0005] Therefore, a leak-proof sampling device for drug detection is proposed to address the problems mentioned above. Utility Model Content

Furthermore, there is no need to transfer the hair, making the use of the drug detection and sampling device more convenient and faster. Therefore, the practicality of this leak-proof drug detection sampling device is enhanced.

[0030] Among them, a sampling knife 7 is slidably connected to the other side of the bottom end of the sample storage box 1, and a slot 8 is opened on one side of the sampling knife 7. A pressing block 9 is fixedly connected to one end of the sampling knife 7, and a limiting rod 10 is fixedly connected to one side of the pressing block 9. A return spring 23 is sleeved on the outer side of the limiting rod 10. A locking tooth 11 is fixedly connected to the inner side of the top end of the sample storage box 1, and an external thread 12 is opened on the outer side of the top end of the sample storage box 1. The outer side of the limiting rod 10 is slidably connected to the side of the bottom end of the sample storage box 1 near the sampling knife 7, and one side of the pressing block 9 overlaps with the outer side of the sample storage box 1. The two ends of the return spring 23 are fixedly connected to the pressing block 9 and the sample storage box 1 respectively. Figures 1-4 As shown, by setting a limiting rod 10 and a return spring 23 on one side of the sampling knife 7, it is easy to reset the sampling knife 7 and make it easier and faster to cut hair. By setting the locking teeth 11 and the external thread 12, it is easy to enhance the locking between the sealing cap 13 and the sample storage box 1, thus making the practicality of the leak-proof drug detection sampling device stronger.

[0031] The sample storage box 1 has a sealing cap 13 attached to its top, and an internal thread 14 is provided in the middle of the bottom surface of the sealing cap 13. A locking block 16 is fixedly connected to one side of the inner wall of the sealing cap 13, and an adjusting block 17 is fixedly connected to one side of the bottom end of the locking block 16. An adjusting groove 18 is provided at the upper end of the adjusting block 17, and a connecting rod 19 is fixedly connected to the top of the adjusting groove 18.

Therefore, the practicality of this leak-proof drug detection sampling device is enhanced.

[0032] Working principle: When using this leak-proof drug detection sampling device, firstly, insert the sealing cap 13 into the middle of the sample storage box 1 near the locking teeth 11 through the locking block 16, and then rotate the sealing cap 13 to connect the sealing cap 13 with the external thread 12 on the outside of the sample storage box 1 through the internal thread 14.

[0033] Next, place the sample box 1 near the side of the pressing block 9 and the side near the hair, and move the sampling knife 7 towards the clamping rod 5 by pressing it to cut the hair. After sampling, press the pressing block 9 to push the limiting rod 10 to retract on the return spring 23, and push the sampling knife 7 to move the clamping rod 5 towards the outside of the compression springs 4 on both sides of the positioning rod 3 in the middle of the relief groove 2. This allows the clamping rod 5 to engage with the middle of the slot 8 on one side of the sampling knife 7 through the locking block 6, thus completing the sampling of the drug test substance.

[0034] Finally, when removing the hair, the aluminum foil layer 22 is opened to expose the slot 21, and the tool is inserted into the slot 21. The rotating block 20 is rotated in the rotating groove 15.

The adjustment block 17 drives the locking block 16 to retract, and the locking block 16 separates from the locking tooth 11. The sealing cap 13 can then be separated from the sample box 1 by rotating the sealing cap 13.
