Description

Technical Field

[0001] This utility model relates to the field of hair inspection technology, specifically a pretreatment device for hair inspection. Background Technology

[0002] DNA extraction from hair samples is a crucial technique in forensic, genetic, and biomedical research. Before hair testing, hair polishing equipment is usually used to polish the hair. However, some existing hair polishing equipment requires manual fixing of sample tubes. For example, the hair polishing equipment with publication number CN221124000U includes a body, a mounting component, and a display component. The top of the body has a mounting frame, and one side of the mounting frame has a limiting frame. The limiting frame has a stop bar connected to it via a rotating shaft, and the bottom of the other end of the stop bar has a fixing buckle A. The other side of the mounting frame has a fixing frame, and the fixing frame has a fixing buckle B. Pulling the fixing buckle B outward exposes the notch at the top of the fixing buckle B. At this time, the spring returns, causing the stop bar to lift. The test tube can then be inserted into the limiting hole of the mounting frame. After the test tube is installed, the stop bar is rotated, and the fixing buckle A is used to squeeze the fixing buckle B, forcing the fixing buckle A into the fixing buckle B. Although multiple sample tubes can be fixed at the same time, after the staff manually fixes the test tubes, the device cap still needs to be fastened, which affects the operating efficiency and is inconvenient to use.

[0003] While existing technologies may already offer solutions to the aforementioned problems, this case aims to provide an alternative or replacement technical solution. Summary of the Invention

[0017] Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0018] Example: Those skilled in the art shall connect all electrical components and their compatible power supplies in this case with wires, and select appropriate controllers according to actual conditions to meet control requirements. The specific connection and control sequence shall refer to the working principle described below, in which the electrical components are connected in sequence. The detailed connection methods are well-known in the art. The following mainly introduces the working principle and process, without explaining the electrical control.

[0019] Please see Figure 1-3 In order to solve the problem that although some hair grinding equipment can fix multiple sample tubes at the same time, after the staff manually fixes the test tubes, the device still needs to be closed, which affects the operation efficiency and is inconvenient to use, this technical solution is designed. The detailed technical solution is as follows.

[0020] A pretreatment device for hair inspection includes a body 1, a control panel 2 on the body 1, an operating space on the body 1, a cover 3 on the body 1 corresponding to the operating space, a power structure on the operating space, a pressing structure above the power structure, and the pressing structure is located on the cover 3.

[0021] It should be noted that the structure and working principle of the main body 1, control panel 2, and cover 3 can be referenced from the Shanghai Yetuo CBMF-06 portable hair polishing instrument. It is important to emphasize that the main body 1 and cover 3 have a locking function, which is existing technology and will not be elaborated upon here. The power structure and pressing structure are used to clamp the sample tube, which is the sample tube used in existing technology, containing polishing balls, hair samples, and lysis solution. This is also existing technology and will not be elaborated upon here. The control panel 2 has a built-in microcontroller, which can be programmed to control the device by writing control programs. This is also existing technology and will not be elaborated upon here.

[0022] Specifically, the power structure includes a rotating seat 4, which is movably inserted into the inner bottom surface of the operating space. A slot 5 is installed on the rotating seat 4, and an clearance opening is provided in the center of the slot 5. Multiple guide slots 6 are installed in a circular array on the inner bottom surface of the slot 5. A slider 7 is movably installed on each guide slot 6. A placement plate 8 is installed on the slider 7. Multiple first spring columns 9 are provided between the placement plate 8 and the slot 5. A rotation drive assembly is provided on the slot 5, and a lifting drive assembly is movably attached to the lower wall of the placement plate 8.

[0023] It should be noted that the placement tray 8 is used to insert sample tubes. Preferably, the placement tray 8 has multiple slots, and each slot is equipped with an anti-slip rubber sleeve 22. The sample tubes are inserted into the slots. The anti-slip rubber sleeve 22 is used to increase the friction between the slots and the sample tubes, and at the same time prevents the slots and sample tubes from wearing each other.

[0024] Specifically, the pressing structure includes multiple second spring pillars 10, which are installed on the inner top surface of the cover 3. One end of each second spring pillar 10 is provided with a mounting plate 11, and a support rod 12 is installed on the lower wall of the mounting plate 11. The support rod 12 is coaxially installed with the rotating seat sleeve 4, and a rotating pressure plate 13 is movably fitted onto one end of the support rod 12.

[0025] It should be noted that after the sample tube is placed on the slot 5, the cover 3 is fastened and installed on the machine body 1. The rotating pressure plate 13 presses against the top of the sample tube. At this time, the multiple second spring columns 10 and the multiple first spring columns 9 are in a semi-compressed state, with still room for expansion and contraction. This allows multiple sample tubes to be fixed at the same time, improving operating efficiency and making it convenient to use. The operator operates the control panel 2 to make the device perform grinding work, that is, the lifting drive component and the rotating drive component work.

[0026] Specifically, the lifting drive assembly includes two support frames 14, which are installed on the inner bottom surface of the operating space. The two support frames 14 are movably inserted through the clearance opening. A rotating rod 15 is movably inserted into the two support frames 14. A ball 16 is fixedly fitted on the rotating rod 15 between the two support frames 14. The ball 16 and the rotating rod 15 are eccentrically installed. The ball 16 is movably attached to the lower wall of the placement plate 8. A first motor 17 is installed at one end of the rotating rod 15.

[0027] It should be noted that when the lifting drive assembly is working, the first motor 17 starts, driving the rotating rod 15 and the ball 16 to rotate. Since the ball 16 and the rotating rod 15 are eccentrically installed, when the ball 16 rotates to the highest point of its circular motion, the ball 16 will push the placement plate 8 to move upward. The placement plate 8 drives the slider 7 to move in the guide groove 6. The slider 7 and the guide groove 6 play the role of guiding and supporting the placement plate 8. At this time, the first spring column 9 extends and the second spring column 10 is compressed. When the ball 16 rotates to the lowest point, due to the elasticity of the first spring column 9, the placement plate 8 will fall downward. The placement plate 8 and the sample test tube on it thus achieve the up and down vibration action.

[0028] Specifically, the rotation drive assembly includes a mounting sleeve 18, which is coaxially mounted on the lower wall of the slot seat 5 with the rotating seat sleeve 4. An external gear ring 19 is fitted on the outer wall of the mounting sleeve 18, and a gear 20 meshes on the external gear ring 19. A second motor 21 is mounted on the gear 20.

[0029] It should be noted that while the lifting drive assembly is working, the rotation drive assembly is also working, that is, the second motor 21 is working, driving the gear 20 to rotate. Since the gear 20 meshes with the outer gear ring 19, the rotation of the gear 20 will drive the outer gear ring 19 and the mounting sleeve 18, rotating seat sleeve 4 and slot seat 5 coaxial with it to rotate together. The rotation of the slot seat 5 will drive the placement tray 8 and the sample tube inserted on it to rotate together. The rotating pressure plate 13 rotates at one end of the support rod 12 along with the rotation of the test tube. Under the simultaneous action of the lifting drive assembly and the rotation drive assembly, the sample tube not only realizes the up and down vibration action, but also performs rotational motion. This compound motion mode can more effectively promote the mixing and collision of the grinding balls in the hair sample and lysis solution, thereby accelerating the grinding and lysis process of the hair sample.

[0030] As a preferred and further option, a first stabilizing frame 23 is provided between the first motor 17 and the support frame 14 for fixed installation between the first motor 17 and the support frame 14.

[0031] As a preferred and further option, a second stabilizing bracket 24 is provided between the second motor 21 and the operating space for fixed installation between the second motor 21 and the operating space.

[0032] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
