[0022] See also Figures 1-4 , the utility model provides a technical solution:

[0023] A convenient sampling device for a sample retention scale comprises a fixed plate 1 fixedly connected to the sample retention scale, with several equally spaced sample retention boxes 2 fixedly mounted on the outer wall of the fixed plate 1. An L-shaped support frame 3 is fixedly connected to the fixed plate 1, with an extension rod 4 slidably mounted below the L-shaped support frame 3. A first electric telescopic rod 5 is slidably mounted at the bottom of the extension rod 4, with a clamping mechanism 7 fixedly mounted on the end of the piston rod of the first electric telescopic rod 5. A disinfection box 6 is fixedly mounted near the bottom of the circumferential outer wall of the first telescopic rod, with an ultraviolet light panel 61 fixedly mounted on each of the four inner walls of the disinfection box 6. A retractable sealing plate 60 is provided near the bottom of the disinfection box 6. When the piston rod of the electric telescopic rod is retracted to its shortest position, the clamping mechanism 7 is located within the disinfection box 6. The device is fixedly connected to the sample retention scale via the fixed plate 1, with equally spaced sample retention boxes 2 provided on the fixed plate 1 for storing samples. The device also includes an L-shaped support frame 3, with an extension rod 4 slidably mounted below it. A first electric telescopic rod 5 is slidably mounted at the bottom of the extension rod 4. A clamping mechanism 7 is fixed to the end of the piston rod of the first electric telescopic rod 5 for clamping the sample. A disinfection box 6 is also fixed to the outer wall of the first electric telescopic rod 5 near the bottom. The disinfection box 6 houses an ultraviolet light panel 61 for disinfecting the clamping mechanism 7, and a removable sealing plate 60 is installed at the bottom of the disinfection box 6. When the piston rod of the electric telescopic rod is retracted to its shortest position, the clamping mechanism 7 is located within the disinfection box 6, enabling immediate disinfection after sampling and improving the hygienic safety of the sampling process.

[0024] As a preferred embodiment of the present invention, a sample chamber is provided in each sample box 2, and a cover 20 is provided above each sample chamber. Such a design can protect the sample from external contamination and facilitate the storage and access of the sample.

[0025] As a preferred embodiment of this embodiment, the clamping mechanism 7 includes a U-shaped plate 70 that secures the bottom of the first electric telescopic rod 5. Two clamping plates 72 are slidably mounted within the U-shaped plate 70. Two second electric telescopic rods 71 are symmetrically fixedly mounted on the inner wall of the U-shaped plate 70. The two clamping plates 72 are respectively fixedly connected to the piston rods of the two second electric telescopic rods 71. The second electric telescopic rods 71 pass through the clamping plates 72 located on the same side as them. The clamping mechanism 7 includes the U-shaped plate 70, the clamping plates 72, and the second electric telescopic rod 71. The second electric telescopic rod 71 drives the clamping plates 72 to move, achieving stable clamping and release of the sample, improving the accuracy and efficiency of sampling.

[0026] As a preferred embodiment of this embodiment, a first screw rod 31 is rotatably mounted within the L-shaped support frame 3. A first drive block 32 is threadedly connected to the first screw rod 31 and is slidably connected to the inner wall of the top of the L-shaped support frame 3. The extension rod 4 is fixedly connected to the first drive block 32. A first motor 30 is mounted on the outer wall of the L-shaped support frame 3 with an output shaft coaxially fixed to the first screw rod 31. The first motor 30 drives the first screw rod 31 to rotate, causing the first drive block 32 to drive the extension rod 4 to slide on the support frame, thereby adjusting the horizontal position of the extension rod 4, and further adjusting the horizontal position of the clamping mechanism 7 so that it can align with different sample boxes 2.

[0027] As a preferred embodiment of this embodiment, a second screw rod 41 is rotatably mounted within the extension rod 4. A second drive block 40 is threadedly connected to the second screw rod 41 and is slidably connected to the inner wall of the top of the extension rod 4. The first electric telescopic rod 5 is fixed to the bottom of the second drive block 40. A second motor 42 is mounted on the extension rod 4 with an output shaft coaxially fixed to the second screw rod 41. The second screw rod 41 and the second drive block 40 are rotatably mounted within the extension rod 4. The second motor 42 drives the second screw rod 41 to rotate, causing the second drive block 40 to drive the first electric telescopic rod 5 to slide on the extension rod 4, thereby achieving position adjustment of the clamping mechanism 7, allowing it to more accurately approach or move away from the sample box 2.

[0028] As a preferred embodiment of the present invention, when the piston rod of the first electric telescopic rod 5 is extended to its longest position, the clamping mechanism 7 is close to the top of the sample box 2. This design enables the clamping mechanism 7 to conveniently place the sample into the sample box 2.

[0029] As a preferred embodiment of the present invention, a reflector is fixedly mounted on the top of the sealing plate 60. Such a design can utilize the reflector to reflect the light of the ultraviolet lamp panel 61, thereby enhancing the disinfection effect and ensuring that the clamping mechanism 7 is fully and evenly disinfected in the disinfection box 6.

[0030] When using the convenient sampling device for a sample retention scale, the device is first fixedly connected to the sample retention scale via a fixed plate 1 to ensure the stability of the device. The fixed plate 1 is provided with evenly spaced sample boxes 2 for storing samples. Each sample box 2 has a sample retention chamber, and a cover 20 is provided above each sample retention chamber to protect the sample from external contamination and facilitate sample storage and access.

[0031] When sampling is required, the first motor 30 is controlled to drive the first screw rod 31 to rotate, so that the first drive block 32 slides on the L-shaped support frame 3, thereby driving the outrigger rod 4 to move horizontally, and adjusting the horizontal position of the clamping mechanism 7. Then, the second motor 42 is controlled to drive the second screw rod 41 to rotate, so that the second drive block 40 slides on the outrigger rod 4, thereby driving the first electric telescopic rod 5 to move, and adjusting the position of the clamping mechanism 7 so that it is closer to the sample box 2 more accurately.

[0032] Once the clamping mechanism 7 is properly positioned, the piston rod of the first electric telescopic rod 5 is extended, allowing the clamping mechanism 7 to approach the raw material on the sample retention scale. The clamping mechanism 7 comprises a U-shaped plate 70, a clamping plate 72, and a second electric telescopic rod 71. The clamping plate 72 is driven and moved by the second electric telescopic rod 71 to achieve stable clamping of the sample. After clamping the sample, the piston rod of the first electric telescopic rod 5 is retracted, allowing the clamping mechanism 7 to carry the sample retention box 2. The box lid 20 is then opened, allowing the sample to be placed into the sample retention chamber.

[0033] After sampling is completed, when the piston rod of the first electric telescopic rod 5 is retracted to its shortest position, the clamping mechanism 7 is located within the disinfection box 6. At this point, the ultraviolet light panel 61 can be activated to disinfect the clamping mechanism 7 to ensure the hygienic safety of the sampling process. The clamping mechanism 7 should be cleaned before being placed in the disinfection box 6. A removable sealing plate 60 is provided at the bottom of the disinfection box 6. A reflector is fixedly mounted on the top of the sealing plate 60. This reflector can be used to reflect the light from the ultraviolet light panel 61, enhancing the disinfection effect and ensuring that the clamping mechanism 7 is fully and evenly disinfected within the disinfection box 6.

[0034] In summary, the convenient sampling device for a sample retention scale of the utility model realizes a convenient, accurate and hygienic sampling operation of samples through a precise mechanical structure and an intelligent control method.
