Technical Field

[0001] This utility model belongs to the field of sampling devices, specifically, it relates to a quantitative sampling device for freeze-dried powder. Background Technology

[0002] Freeze-dried powder is a sterile powder injection made by freezing liquid medicine into a solid state under sterile conditions and then sublimating and drying the water under vacuum.

[0003] Chinese patent CN220473040U discloses a quantitative sampling device for probiotic freeze-dried powder. By installing a threaded rod on the surface of the sampling cylinder, and cooperating with a rotating device and a threaded cylinder, a sliding device and a U-shaped connecting frame and a sliding groove, the moving plate inside the sampling cylinder can be moved. By aligning the moving plate with the scale line, quantitative sampling of freeze-dried powder can be performed, which improves the convenience and practicality of the device.

[0004] However, with the aforementioned probiotic freeze-dried powder quantitative sampling device, when the sampling device enters the freeze-dried powder pile, the sampling port of the sampling device is generally relatively small, and since freeze-dried powder is a powder, it is easy to accumulate at the sampling port, affecting the sampling efficiency.

[0005] In view of this, this utility model is hereby proposed. Utility Model Content

Detailed Implementation

[0025] The present invention will now be described in further detail with reference to the accompanying drawings.

[0026] Please see Figure 1-3 As shown, this embodiment provides a quantitative sampling device for freeze-dried powder, including a transparent sampling barrel 1. The transparent sampling barrel 1 has a scale on its side. A limiting block 2 is slidably fitted inside the transparent sampling barrel 1. A threaded rod 3 that is threadedly fitted to the bottom of the limiting block 2 is rotatably fitted to the transparent sampling barrel 1. A protrusion 4 is provided on one side of the transparent sampling barrel 1. A groove 5 that extends into the protrusion 4 is provided on the inner wall of the transparent sampling barrel 1. A transmission rod 6 that passes through the limiting block 2 is rotatably fitted on the bottom surface of the inner wall of the transparent sampling barrel 1. A driving mechanism 7 for driving the transmission rod 6 to rotate is provided on the side of the protrusion 4. A sampling port 8 is connected to the upper side of the transparent sampling barrel 1. A plurality of oblique strips 9 are arranged circumferentially at one end of the transmission rod 6 that extends out of the transparent sampling barrel 1 and the sampling port 8.

[0027] By rotating the threaded rod 3, the limiting block 2 is driven to slide inside the transparent sampling bucket 1. The position of the limiting block 2 can be adjusted by the scale on the transparent sampling bucket 1 to facilitate the adjustment of the sampling amount of the transparent sampling bucket 1 and achieve quantitative sampling. The transparent sampling bucket 1 is inserted into the freeze-dried powder pile through the handle 13. Then, the drive mechanism 7 drives the transmission rod 6 and the inclined bar 9 to rotate. The freeze-dried powder is guided into the sampling port 8 through the bottom surface of the inclined bar 9 to improve the sampling efficiency.

[0028] Please see Figure 2 As shown, in this embodiment, the height of the upper side and bottom surface of the inclined bar 9 gradually decreases from one end to the other. The driving mechanism 7 includes a driving rod 701 rotatably fitted in the groove 5, two synchronous pulleys 702 respectively fixedly sleeved on the driving rod 701 and the transmission rod 6, a synchronous belt 703 transmissionally fitted between the two synchronous pulleys 702, and a first handwheel 704 fixed at one end of the driving rod 701 that extends out of the groove 5, which facilitates the rotation of the first handwheel 704. The first handwheel 704 drives the transmission rod 6 and the inclined bar 9 to rotate through the driving rod 701, the synchronous pulleys 702, and the synchronous belt 703.

[0029] Please see Figure 2-3As shown, in this embodiment, the bottom end of the transparent sampling barrel 1 is rotatably fitted with a second handwheel 10, and the threaded rod 3 is threadedly fitted into the second handwheel 10. The side of the threaded rod 3 is provided with a notch 11, and the cross-section of the notch 11 is a crescent-shaped structure. The bottom end of the second handwheel 10 is provided with a crescent-shaped hole 12, and one end of the threaded rod 3 is slidably fitted into the crescent-shaped hole 12. A bearing is embedded in the bottom end of the transparent sampling barrel 1, and the upper end of the second handwheel 10 is provided with an annular protrusion, which is fixed in the bearing. This facilitates the rotation of the threaded rod 3 by rotating the second handwheel 10, thereby causing the limiting block 2 to slide within the transparent sampling barrel 1. The bearing improves the stability of the rotation of the second handwheel 10.

[0030] Please see Figure 1-2 As shown, in this embodiment, the height of the top surface of the inner wall of the transparent sampling barrel 1 gradually decreases from the end near the sampling port 8 to the end away from the sampling port 8. This facilitates the adaptation of the cone-shaped structure formed after the freeze-dried powder enters the transparent sampling barrel 1 through the sampling port 8, thereby improving the adhesion rate between the freeze-dried powder and the inner wall of the transparent sampling barrel 1 and improving the sampling accuracy of the transparent sampling barrel 1. The upper part of the limiting block 2 has a frustum-shaped structure, and the lower part of the limiting block 2 has a disc-shaped structure, which facilitates the upper part of the limiting block 2 to adhere to the top surface of the inner wall of the transparent sampling barrel 1.

[0031] Please see Figure 1-2 As shown, the transparent sampling bucket 1 in this embodiment is provided with a handle 13 on the upper side. The handle 13 is provided with an outward flange on the upper side, which makes it easy to control the movement of the transparent sampling bucket 1 through the handle 13. By setting the outward flange, it is easier to reduce the probability of the user's hand slipping off the handle 13.

[0032] Working principle: Rotating the second handwheel 10 drives the threaded rod 3 to rotate, causing the limiting block 2 to slide inside the transparent sampling bucket 1. The position of the limiting block 2 can be adjusted by the scale on the transparent sampling bucket 1 to facilitate the adjustment of the sampling amount of the transparent sampling bucket 1 and achieve quantitative sampling. The transparent sampling bucket 1 is inserted into the freeze-dried powder pile through the handle 13. Then, the first handwheel 704 is rotated. The first handwheel 704 drives the transmission rod 6 and the inclined bar 9 to rotate through the drive rod 701, the synchronous wheel 702, and the synchronous belt 703. The freeze-dried powder is guided into the sampling port 8 through the bottom surface of the inclined bar 9 to improve the sampling efficiency.
