Description

Technical Field

[0001] This utility model relates to the field of hair detection technology, specifically to a hair detection drug extraction device. Background Technology

[0002] Hair analysis for drug use is a highly practical and widely applicable method that has gained popularity in forensic departments in recent years. Drug components or metabolites in a drug user's body are used in the synthesis of tissue components during hair growth. By using an extraction detection device to identify the components of hair, it is possible to quickly determine whether a suspect has used drugs. The extraction device for drugs in hair, as described in authorization announcement number CN215065598U, involves placing the extraction device in a grinder for shaking and extraction. After the hair sample is ground into powder and fully contacted with the extraction liquid, the drug components in the hair dissolve into the extraction liquid. Five to ten drops of the extraction liquid are then dropped into the circular hole of the detection area of ​​a colloidal gold drug detection kit, and the results can be observed after standing for 3 to 5 minutes. However, the existing technology still has the following drawbacks:

[0003] 1. The grinding effect of existing technologies is generally poor, requiring a long period of oscillation to meet the detection requirements, which affects the detection efficiency;

[0004] 2. Existing technology requires manual tightening of the cap for sealing, which is time-consuming and labor-intensive, and the sealing effect is also affected by the amount of manual labor. Utility Model Content

The mounting components 7 include: a locking block 71, a guide groove 72, two telescopic rods 73, and two fixing balls 74. The locking block 71 is fixedly connected to the lower end of the cover plate 4. The guide groove 72 is located on the upper side of the connecting plate 3. The two telescopic rods 73 are fixedly connected to the guide groove 72 through guide holes formed in the inner wall of the guide groove 72. Springs are fitted onto the telescopic rods 73. The two fixing balls 74 are used in conjunction with the locking block 71 and are respectively connected to the two telescopic rods 73. The fixed connection is achieved by abutting the side wall of the locking block 71 with the fixed ball 74. The front and rear ends of the spring are fixedly connected to the fixed ball 74 and the telescopic rod 73 respectively. By bringing the cover plate 4 close to and pressing it against the connecting plate 3, the locking block 71 is inserted between the two fixed balls 74. Under the action of the telescopic rod 9 and the spring, the fixed ball 74 will be pushed and pressed against the side wall of the locking block 71 to fix it, thereby achieving quick fixation of the cover plate 4 and ensuring the sealing effect. When disassembling, the cover plate 4 can be pulled up, which is convenient, quick and saves time and effort.
