[0014] In order to achieve grip control, further, a button is fixedly installed on one side of the handle, and the button is electrically connected to the integrated control board of the handle. A battery is fixedly installed inside the handle, and the integrated control board of the handle is also electrically connected to the motor and the battery respectively.

[0015] In order to achieve the change in the outer diameter of the driven wheel and thus adapt to collection belts of different thicknesses, further, the driven wheel includes a rotating tube, which is rotatably installed inside the casing, and a plurality of slides are slidably installed on the outside of the rotating tube through a first spring, and the outer part of each slide is fixedly connected to a contact plate, and the contact plate is arranged in an arc shape, and a plurality of the contact plates form a cylinder for contact transmission of the transmission belt, and a cone cylinder is slidably installed inside the rotating tube, and the inner sides of the plurality of slides are in contact with the outer wall of the cone cylinder, and the cone cylinder is driven to perform an ejection action.

[0016] In order to achieve rapid adjustment of the outer diameter of the driven wheel, the detection device is further provided with an adjustment component, which includes an elastic support member, a slider connected to the output end of the elastic support member, the slider is slidably installed in the inner wall of the casing, and a first screw rod is rotatably installed inside the slider, one side of the first screw rod is externally screwed to the cone cylinder, and one end of the first screw rod passes through the casing and is fixedly connected to a knob.

[0017] The cam is secured to the chassis and is provided with a first gear which is secured to the chassis and is in a condition whereby the first gear is engaged with the first gear and the second gear is engaged with the first gear.

[0020] 1. The biopharmaceutical detection equipment rod is inserted into the sampling and pressing track of the sampling and pressing assembly. The head of the collection belt is firmly connected to the sampling and pressing assembly to ensure its accurate position. The sampling and pressing assembly drives the collection belt to move along the pressing track.

[0022] 3. The rod of the biopharmaceutical detection equipment, when the first belt body and the second belt body are pressed together, the thick magnetic strip will be inserted into the installation slot of the first belt body, forming a magnetic connection with the thin magnetic strip, which ensures that the two belt bodies can be firmly connected when pressed together, avoiding separation or misalignment during use. A placement slot is provided at the rear of the casing, which is specifically used to store the collection belt. At the same time, the guide slot provides effective guiding support for the transmission of the collection belt. The design of the placement slot and the guide slot helps to ensure the smooth movement of the collection belt during operation, reduce friction and resistance, and facilitate the user to place the collection belt. Continuous multiple sampling can be performed without frequent opening of the cover like traditional devices. The outside of the first belt body and the second belt body is provided with a sampling slot. When the two belt bodies are pressed together, the two sampling slots are combined into a cavity for storing collected samples. The design of the cavity effectively improves the accuracy and convenience of sampling, while ensuring the sealing of the sample during storage.

DETAILED DESCRIPTION

[0038] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0039] In the description of the present invention, it is necessary to understand that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship are based on the orientation or position relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0040] Example:

[0041] Reference Figure 1-Figure 11 A biopharmaceutical detection device includes a housing 1, characterized in that a sampling pressing component 4 with a pressing track is fixedly installed on the housing 1, and a collecting belt 5 is inserted inside the pressing track of the sampling pressing component 4, wherein the head of the sampling bag is pulled by the sampling pressing component 4 and transmitted inside the pressing track of the sampling pressing component 4, wherein when the head of the housing 1 is inserted into the sampling liquid, the two collecting belts 5 are driven by the pressing component to perform a pressing and collecting action.

[0042] In the above-mentioned biopharmaceutical detection device, first, the collection belt 5 is inserted into the pressing track of the sampling pressing component 4, and the head of the collection belt 5 is firmly connected to the sampling pressing component 4 to ensure that its position is accurate. The sampling pressing component 4 drives the collection belt 5 to move along the pressing track. When the collection belt 5 reaches the end of the track, the pressing component will drive the two belt bodies of the collection belt 5 to accurately fit and press, thereby completing the quantitative collection and sealed storage of the sample. After the pressing is completed, the collection belt 5 is safely brought back under the control of the pressing component, and the collected sample is kept in a light-proof and sealed state in the sampling slot 503 for subsequent detection.

[0043] The movement of the collection belt 5 is precisely controlled by the pressing track and the sampling pressing assembly 4 to ensure that the collection belt 5 is always in the correct position during pressing, eliminating the possibility of misalignment, and fundamentally improving the integrity and accuracy of sampling.

[0044] In this embodiment, the head of the housing 1 is provided with an opening, and the sampling and pressing assembly 4 includes a driving wheel 401, and two driving wheels 401 are provided, and the two driving wheels 401 are rotatably installed inside the housing 1. In order to realize the transmission of the first belt body 501 and the second belt body 502, each driving wheel 401 is respectively connected to a driven wheel 404 through a transmission belt 402, and a plurality of slots 403 are equidistantly opened on the outside of the transmission belt 402. The collection belt 5 includes a first belt body 501 and a second belt body 502, and the first belt body 501 and the second belt body 502 have the same structure. The first belt body 501 and the second belt body 502 are fixedly connected with a plug plate 507 at the head, and the plug plate 507 is movably inserted into the slot 403. In order to realize the guided pressing of the first belt body 501 and the second belt body 502, further, the two transmission belts 402 are formed with a pressing track, and the outside of the two transmission belts 402 cooperates with the inner wall of the housing 1 to form a transmission track for guidance.

[0045] Inside the housing 1, two transmission belts 402 form a pressing track for controlling the guiding pressing of the first belt body 501 and the second belt body 502 during the transmission process. The outer parts of the two transmission belts 402 also cooperate with the inner wall of the housing 1 to form a stable transmission track, ensuring that the collection belt 5 always maintains an accurate direction and position during the transmission process without offset or sliding, thereby achieving accurate guidance and stable transmission. When the driving wheel 401 and the driven wheel 404 drive the transmission belt 402 to rotate, the first belt body 501 and the second belt body 502 plugged into the transmission belt 402 move along the pressing track and guide to the opening of the head of the housing 1. At this position, the guide track allows the first belt body 501 and the second belt body 502 to fit and press accurately, ensuring that the liquid samples in the grooves of the first belt body 501 and the second belt body 502 can be quantitatively collected and sealed. After the pressing and sampling is completed, the transmission belt 402 continues to move, and the pressed first belt body 501 and the second belt body 502 are transmitted backwards, and discharged from the rear part of the housing 1 along the transmission track. The exit is released by side sliding, and the collection belt 5 can be separated from the transmission belt 402, completing the whole sampling process.

[0046] In order to further realize electric drive, a handle 2 is fixedly installed at the lower part of the housing 1, a motor 6 is fixedly installed inside the handle 2, a first gear 8 is fixedly connected to the output end of the motor 6, the first gear 8 is meshedly connected to the second gear 9, the first gear 8 and the second gear 9 pass through the lower part of the housing 1 and are fixedly connected to the two driving wheels 401. In order to realize grip control, a button 3 is further fixedly installed on one side of the handle 2, the button 3 is electrically connected to the integrated control board of the handle 2, a battery is fixedly installed inside the handle 2, and the integrated control board of the handle 2 is also electrically connected to the motor 6 and the battery respectively.

[0047] In order to facilitate operation and control, a control button 3 is installed on one side of the handle 2. The button 3 is electrically connected to the motor 6 through the integrated control panel. The user can start or stop the motor 6 by pressing the button 3 to control the rotation of the drive wheel 401. At the same time, the handle 2 is equipped with a battery, which provides power to the motor 6 through the integrated control panel to ensure the portability and independence of the device, and is convenient for use in an environment without an external power supply. After the motor 6 is started, it drives the first gear 8 to rotate, and the first gear 8 drives the second gear 9 to rotate by engaging the transmission belt 402. The first gear 8 and the second gear 9 pass through the lower part of the housing 1 respectively and are fixedly connected to the two drive wheels 401, thereby realizing the synchronous rotation of the drive wheels 401 and providing power for the operation of the transmission belt 402.

[0048] In order to realize the change of the outer diameter of the driven wheel 404 and thus adapt to the collection belt 5 of different thicknesses, the driven wheel 404 further includes a rotating tube 4041, which is rotatably installed inside the casing 1, and a plurality of slides 4042 are slidably installed on the outside of the rotating tube 4041 through first springs 4044, and the outer part of each slide 4042 is fixedly connected with a contact plate 4043, and the contact plate 4043 is arranged in an arc shape. A plurality of contact plates 4043 form a cylinder for contact transmission of the transmission belt 402, and a cone cylinder 4045 is slidably installed inside the rotating tube 4041, and the inner sides of a plurality of slides 4042 are in contact with the outer wall of the cone cylinder 4045, and the cone cylinder 4045 is driven to perform an ejection action. In order to realize the rapid adjustment of the outer diameter of the driven wheel 404, the detection device is further provided with an adjustment component 7, which includes an elastic support member 704, and the output end of the elastic support member 704 is connected to a slider 703, the slider 703 is slidably installed in the inner wall of the casing 1, and a first screw rod 702 is rotatably installed inside the slider 703, one side of the first screw rod 702 is externally screwed to the cone cylinder 4045, and one end of the first screw rod 702 passes through the casing 1 and is fixedly connected to a knob 701.

[0049] In order to adjust the outer diameter of the driven wheel 404, the cone 4045 will perform an ejection action during the adjustment process. When the cone 4045 is pushed outward, the slide plate 4042 in contact with it is also pushed outward, thereby increasing the outer diameter of the driven wheel 404. After the cone 4045 is ejected to a suitable position, each slide plate 4042 is kept at a new outer diameter position to adjust the outer diameter of the driven wheel 404, thereby adapting to thicker and thinner collection belts 5. On the contrary, when the cone 4045 retracts, the slide plate 4042 returns to its original position under the action of the first spring 4044, reducing the outer diameter to adapt to thicker collection belts 5.

[0050] The user can rotate the knob 701 outside the housing 1 to drive the first screw 702 to rotate, thereby driving the cone 4045 to slide back and forth in the rotating tube 4041. The change in the moving position of the cone 4045 causes the slide plate 4042 to be pushed to different degrees, thereby adjusting the outer diameter of the driven wheel 404.

[0051] In order to achieve adaptive position change of the driven wheel 404 after the outer diameter of the driven wheel 404 is adjusted, and to avoid the problem of the transmission belt 402 being too short, further, the elastic support member 704 includes a fixed plate 7041, the fixed plate 7041 is fixed inside the housing 1, the middle part of the fixed plate 7041 is arranged, a first sliding plate 7043 is slidably installed inside the fixed plate 7041, one end of the first sliding plate 7043 is fixedly connected to a sliding rod 7042, one end of the sliding rod 7042 passes through the fixed plate 7041 and is fixedly connected to the slider 703, and the fixed plate 7041 is also slidably installed inside A second sliding plate 7045 is installed, and a second spring 7044 is fixedly connected between the second sliding plate 7045 and the first sliding plate 7043. A second screw rod 7046 is also rotatably installed inside the fixed plate 7041. The second screw rod 7046 is externally screwed to the second sliding plate 7045, and one end of the second screw rod 7046 passes through the casing 1 and is fixedly connected to a third gear 7047. The third gear 7047 is meshingly connected to a fourth gear 7048. The fourth gear 7048 is rotatably installed on the casing 1, and one side of the fourth gear 7048 extends to the outside through the casing 1.

[0052] When the outer diameter adjustment of the driven wheel 404 causes the tension of the transmission belt 402 to change, the buffering force of the second spring 7044 causes the slider 703 to automatically adjust its position, thereby maintaining the tension of the transmission belt 402 stable and preventing the transmission belt 402 from becoming loose or tight due to length changes.

[0053] The user can rotate the fourth gear 7048 outside the housing 1, thereby driving the second screw 7046 to rotate through the gear transmission belt 402. This rotation action will push the second sliding plate 7045 to slide along the fixed plate 7041, change the initial tension of the second spring 7044, ensure smooth transmission, and further improve the adaptability and reliability of the device.

[0054] In order to realize the magnetic connection between the first belt body 501 and the second belt body 502, further, the first belt body 501 and the second belt body 502 are respectively provided with installation grooves, a thin magnetic strip 504 is fixedly installed inside the installation groove of the first belt body 501, and a thick magnetic strip 505 is fixedly installed inside the installation groove of the second belt body 502. When the first belt body 501 and the second belt body 502 are pressed together, the thick magnetic strip 505 is inserted into the installation groove of the first belt body 501 and is magnetically connected to the thin magnetic strip 504. A placement groove 101 for placing the collection belt 5 and a guide groove 102 for guiding the collection belt 5 are provided at the rear of the casing 1. A sampling groove 503 is also provided on the outside of the first belt body 501 and the second belt body 502. After the first belt body 501 and the second belt body 502 are pressed together, the sampling grooves 503 of the first belt body 501 and the second belt body 502 are formed with a cavity for storing samples.

[0055] During operation, when the first belt body 501 and the second belt body 502 are pressed together, the thick magnetic strip 505 will be inserted into the installation slot of the first belt body 501, forming a magnetic connection with the thin magnetic strip 504. This design ensures that the two belt bodies can be firmly connected when pressed together, avoiding separation or misalignment during use.

[0056] The rear part of the housing 1 is provided with a placement slot 101, which is specially used to store the collection tape 5. At the same time, the guide slot 102 provides effective guide support for the transmission of the collection tape 5. The design of the placement slot 101 and the guide slot 102 helps to ensure the smooth movement of the collection tape 5 during operation, reducing friction and resistance. It is also convenient for the user to place the collection tape 5, and continuous multiple sampling can be performed without frequently opening the cover like traditional devices.

[0057] The first belt body 501 and the second belt body 502 are provided with a sampling groove 503 on their exteriors. When the two belt bodies are pressed together, the two sampling grooves 503 are combined into a cavity for storing collected samples. The design of the cavity effectively improves the accuracy and convenience of sampling, while ensuring the sealing of the samples during storage.

[0058] In the present invention, the collection belt 5 is inserted into the pressing track of the sampling pressing assembly 4, and the head of the collection belt 5 is firmly connected to the sampling pressing assembly 4 to ensure that its position is accurate. The sampling pressing assembly 4 drives the collection belt 5 to move along the pressing track. When the collection belt 5 reaches the end of the track, the pressing assembly drives the two belt bodies of the collection belt 5 to accurately fit and press, thereby completing the quantitative collection and sealed storage of the sample. After the pressing is completed, the collection belt 5 is safely brought back under the control of the pressing assembly, and the collected sample is kept in a light-proof and sealed state in the sampling slot 503 for subsequent detection.
