The clamping plate can rotate, and the circular plate can then be clamped and fixed, improving the user's work efficiency. Furthermore, the telescopic column, limiting column, and spring allow the user to insert the telescopic column into the upper end of the limiting column and adjust it according to their needs.

[0004] However, existing pharmaceutical low-temperature sampling anti-contamination clamps are difficult to maintain stability during sampling and cannot effectively prevent samples from coming into contact with the external environment, making samples susceptible to contamination during the sampling process. Utility Model Content

[0005] This invention provides a pharmaceutical low-temperature sampling anti-contamination clamp, which has the advantages of being easy to maintain stability during sampling and effectively preventing the sample from contacting the external environment. This solves the problem that existing pharmaceutical low-temperature sampling anti-contamination clamps are difficult to maintain stability during sampling and cannot effectively prevent the sample from contacting the external environment, resulting in the sample being easily contaminated during the sampling process.

[0006] To facilitate stable sampling and effectively prevent sample contact with the external environment, this utility model provides the following technical solution: a pharmaceutical low-temperature sampling anti-contamination clamp, comprising a protective sleeve and a sliding sleeve disposed inside the protective sleeve, wherein a fixed frame is fixedly connected to one side of the sliding sleeve, and further comprising: a telescopic cylinder disposed on one side of the fixed frame, wherein a clamping assembly is fixedly connected to one end of the telescopic cylinder, the clamping assembly comprising a push block, a bent rod, a rotating seat and a clamping plate; a positioning assembly disposed at one end of the protective sleeve, wherein the positioning assembly comprises a fixed sleeve and a positioning rod, wherein a positioning ring is inserted into one end of the positioning rod; an outer tube is sleeved inside the positioning ring, and a sealing assembly is slidably connected to the top of the outer tube and the protective sleeve, wherein the sealing assembly comprises a baffle and a handle.

[0007] As a preferred embodiment of the present invention, the clamping assembly includes a push block fixedly connected to one end of a telescopic cylinder. Two sets of bent rods are rotatably connected inside the push block. One end of each bent rod is rotatably connected to a rotating seat, and one end of the rotating seat is fixedly connected to a clamping piece.

[0008] As a preferred embodiment of this utility model, the positioning component includes a fixed sleeve disposed at one end of the protective sleeve, and four sets of positioning rods are fixedly connected to one side of the fixed sleeve.

[0014] Compared with the prior art, this utility model provides a pharmaceutical low-temperature sampling anti-contamination clamp, which has the following beneficial effects: This pharmaceutical low-temperature sampling anti-contamination clamp, through the design of its clamping components, works by aligning the protective sleeve with the outer connecting pipe on the pharmaceutical container and inserting it. Then, a hydraulic push rod is activated, pushing the sliding sleeve inside the protective sleeve and extending it into the pharmaceutical container. This activates a telescopic cylinder, which pushes a push block. The two ends of the bent rod then rotate on the push block and a rotating seat, respectively. Since the fixed block remains in place, the rotating seat drives the clamping plates to hold the pharmaceutical sample bottle, preventing the bottle from shaking or slipping during sampling. This ensures the accuracy of the sampling position and depth, while reducing manual intervention and lowering the risk of contamination.

[0015] This pharmaceutical low-temperature sampling anti-contamination clamp, through the design of a protective sleeve, positioning components, and sealing components, allows for smooth docking of the protective sleeve and outer tube by inserting the positioning rod into the insertion hole on the positioning ring during use. Then, by pulling the baffle with the handle, the protective sleeve and outer tube are connected for sampling. After sampling, the baffle is reinserted to seal the connection, thereby significantly reducing the risk of external contamination. It also simplifies the docking process and reduces operation time, making it suitable for scenarios with stringent requirements for sample purity, such as biopharmaceuticals and sterile preparations.

[0021] In this embodiment, during use, the protective sleeve 1 is inserted into the outer connecting pipe 8 on the pharmaceutical container, and then the hydraulic push rod 11 is activated to push the sliding sleeve 2 to slide inside the protective sleeve 1 and penetrate into the pharmaceutical container. Then the telescopic cylinder 4 is activated, which pushes the push block 501. Then the two ends of the bent rod 502 rotate on the push block 501 and the rotating seat 503 respectively. Since the position of the fixed block 10 remains unchanged, the rotating seat 503 drives the clamping plate 504 to clamp the pharmaceutical sample bottle.

[0022] Specifically, the positioning component 6 includes a fixed sleeve 601 disposed at one end of the protective sleeve 1, and four sets of positioning rods 602 are fixedly connected to one side of the fixed sleeve 601.

[0023] In this embodiment, during use, the positioning rod 602 is inserted into the insertion hole on the positioning ring 7 to ensure a smooth connection between the protective sleeve 1 and the outer pipe 8.

[0024] Specifically, the enclosure component 9 includes a baffle 901 slidably connected to the top of the protective sleeve 1, and a handle 902 is fixedly connected to the top surface of the baffle 901.

[0025] In this embodiment, the baffle 901 is pulled by the handle 902 to make the protective sleeve 1 and the outer pipe 8 connected and to carry out the sampling operation. After the sampling is completed, the baffle 901 is reinserted and sealed.

[0026] Specifically, a fixing block 10 is rotatably connected to one end of the rotating seat 503, and the fixing block 10 is fixedly connected to the inner wall of the fixing frame 3.

[0027] In this embodiment, the rotating seat 503 is connected to the inner wall of the fixed frame 3 through the fixed block 10 to form a stable rotation fulcrum; the rigid connection of the fixed block 10 enhances the torsional resistance of the overall structure and is suitable for high-frequency operation in low-temperature environments.

[0028] Specifically, a hydraulic push rod 11 is fixedly connected to one side of the sliding sleeve 2, and the hydraulic push rod 11 is sleeved on one end of the protective sleeve 1.

[0029] In this embodiment, the hydraulic push rod 11 is linked with the sliding sleeve 2 to provide a smooth axial thrust.

[0030] Specifically, the top surface of the protective sleeve 1 is fixedly connected to a handle 12, and the top of both the outer pipe 8 and the protective sleeve 1 are provided with a sliding groove that matches the baffle 901.

[0031] In this embodiment, the handle 12 facilitates the manual operation of the protective sleeve 1 to move or rotate, while the slide groove ensures smooth linear sliding of the baffle 901, enabling rapid opening and closing of the channel and preventing external contaminants from entering during sampling.

[0032] Specifically, the surface of the protective sleeve 1 is provided with a controller 13, and the surface of the positioning ring 7 is provided with an insertion hole that is compatible with the positioning rod 602.

[0033] In this embodiment, the controller 13 is integrated into the surface of the protective sleeve 1. It can programmably control the coordinated action of the telescopic cylinder 4 and the hydraulic push rod 11 to improve the level of automation. The precise matching of the positioning rod 602 with the insertion hole enables rapid positioning and ensures the sealed connection between the outer pipe 8 and the protective sleeve 1.

[0034] The working principle and usage process of this utility model are as follows: In use, the protective sleeve 1 is inserted into the outer tube 8 on the pharmaceutical container. Then, the hydraulic push rod 11 is activated to push the sliding sleeve 2 to slide inside the protective sleeve 1 and penetrate into the pharmaceutical container. Then, the telescopic cylinder 4 is activated, which pushes the push block 501. Then, the two ends of the bent rod 502 rotate on the push block 501 and the rotating seat 503 respectively. Since the position of the fixed block 10 remains unchanged, the rotating seat 503 drives the clamping plate 504 to clamp the pharmaceutical sample bottle. In use, the positioning rod 602 is inserted into the insertion hole on the positioning ring 7 to make the protective sleeve 1 and the outer tube 8 smoothly connected. Then, the baffle 901 is pulled by the handle 902 to make the protective sleeve 1 and the outer tube 8 connected and to carry out the sampling operation. After the sampling is completed, the baffle 901 is reinserted to close the container.

[0035] In summary, this pharmaceutical low-temperature sampling anti-contamination clamp, through the setting of clamping component 5, prevents the bottle from shaking or slipping during sampling, ensuring the accuracy of sampling position and depth, while reducing manual intervention and lowering the risk of contamination. Through the setting of protective sleeve 1, positioning component 6 and sealing component 9, it achieves the effect of significantly reducing the risk of external contamination, while simplifying the docking process and reducing operation time. It is suitable for scenarios with strict requirements for sample purity, such as biopharmaceuticals and sterile preparations.
