DETAILED DESCRIPTION

[0021] The technical solution of the utility model will be clearly and completely described below through specific implementation methods.

[0022] The directional words "front" and "rear" in the present invention are only used for the drawings in the present invention, and are not intended to limit the device of the present invention in actual use. In actual use, the orientation of a fixing device for ampoule filling is determined by the actual orientation.

[0023] The utility model provides a fixing device for ampoule filling, comprising a fixing plate 1 and a movable frame 2 with an inverted U-shaped cross section arranged in front of the fixing plate, wherein a plurality of Y-shaped fixing members 3 are evenly penetrated through the movable frame. Figure 1 As shown, the front end surface of the fixing plate is uniformly provided with several arc-shaped protrusions 4, and the adjacent arc-shaped protrusions form a rear concave curved groove 5 corresponding to the fixing piece. A fixing structure is provided in the movable frame corresponding to each fixing piece, and the diverging part of the fixing piece is a diverging part 6, which is arranged close to the curved groove, and the ampoule bottle is placed in the space formed between the curved groove and fixed. The rest of the fixing piece except the diverging part passes through the movable frame and the fixing structure, and the fixing structure fixes the fixing piece; it also includes a movable adjustment mechanism, which is connected to the movable frame 2, and the movable adjustment mechanism is used to move the movable frame 2 as a whole.

[0024] The fixing structure of the utility model includes a fixing block 7 and a spring 8. Figure 2 and 3 As shown, the fixed block is placed in the movable frame close to the curved groove, the spring is placed away from the curved groove, the fixing piece passes through the fixed block and the spring, and the two ends of the spring contact the fixed block and the inner side of the movable frame respectively; a bolt 10 is provided on the top of the fixed block, the bolt is connected to the fixing block bolt, and the fixing piece is squeezed in the direction of the fixing piece, that is, the fixing piece is squeezed and fixed.

[0025] Preferably, the contact between the two ends of the spring 8 of the utility model and the fixed block 7 and the movable frame 2 is surface contact, that is, the two ends of the spring are annular spring ends 11. When the fixing member is subjected to force, the annular spring ends contact the fixed block and the movable frame, and the surface contact can increase the friction force compared to the point contact, making it less likely to swing or move when squeezed, thereby increasing the stability of the fixing member 3.

[0026] Preferably, the utility model also includes a pad 12. After the fixed block and the spring are provided, there is a gap between the fixed block and the spring and the top of the movable frame (the top during actual use). The gap will increase the possibility of movement of the fixed block and the spring. The pad 12 is arranged at the top of the movable frame, and its thickness is such that the surface close to the fixed block contacts the fixed block and the spring. This arrangement reduces the movable space of the spring and the fixed block and enhances the stability of the fixing.

[0027] The forked portion 6 of the fixing member of the utility model is arc-shaped, and the two forked ends are curved surfaces, which can cooperate with the curved groove to adapt to fixing ampoules of different specifications, while reducing friction with the curved groove surface, and preventing friction debris from entering the drug solution and affecting the quality of the drug.

The telescopic device is connected to one end of the connecting rod 14. The connecting rod 14 and the movable frame 2 are arranged in parallel. The bottoms of the two connecting parts 15 are fixed on the connecting rod, and the tops are detachably connected to one end of the corresponding connecting plates 16. The other ends of the connecting plates 16 are fixed on the end surface of the movable frame 2 away from the curved groove.

[0029] Preferably, the detachable connection between the connecting member 15 and the connecting plate 16 is as follows: Figure 4 As shown, a bolt 10 is provided on the connecting plate, and a rectangular adjustment hole 17 is provided on the connecting plate. The bolt passes through the adjustment hole downward and is connected to the connecting piece bolt. The inner diameter of the adjustment hole is larger than the outer diameter of the vertical part of the bolt. The bolt and the connecting piece bolt are connected so that the bolt can move downward to squeeze the connecting plate to fix it. This setting is convenient for disassembling the movable frame, inspecting and maintaining it, and it is also convenient for adjusting the distance between the movable frame and the curved groove to adapt to ampoules of different specifications.

[0030] When the utility model is used, a fixing device for filling ampoules is used to adjust the distance between the movable frame and the curved groove according to the specifications of the ampoules to be filled through the detachable connection of the connecting piece and the connecting plate. After the adjustment, the bolts on the connecting block and the fixing block are ensured to be stable, and the connecting rod is moved forward through the telescopic device to drive the movable frame forward, and the ampoule to be filled is placed in the corresponding curved groove position, and then the connecting rod and its movable frame are moved backward as a whole through the telescopic device so that the diverging part of the fixing piece fixes the ampoule, and then filling is performed. The telescopic distance of the telescopic device corresponds to ampoules of different specifications, ensuring that the fixing piece fixes the ampoule but does not crush the ampoule.
