[0042] The following will, with reference to the accompanying drawings, elaborate on some embodiments of the present utility model. Without conflict, the following embodiments and the features in the embodiments can be combined with each other.

[0043] Referring to Figure 3 and Figure 4 , this embodiment provides a filling needle assembly for ampoules, including a filling frame 100, a filling needle 200, and a clamping member 300; a vertically arranged through hole 110 is provided on the filling frame 100; a clamping groove 211 is provided on the filling needle 200; the clamping member 300 has a connecting portion 310 and an elastic clamping portion 320, the connecting portion 310 is fixedly connected to the filling frame 100, the elastic clamping portion 320 is arranged close to the orifice of the through hole 110, when the filling needle 200 is placed in the through hole 110, the elastic clamping portion 320 is configured to be clamped with the clamping groove 211, so that the filling needle 200 can be fixed in the through hole 110 and has a tendency to slide upward along the through hole 110.

[0044] In the filling needle assembly of this embodiment, during specific use, the filling needle 200 needs to be placed in the vertically arranged through hole 110 on the filling frame 100. Among them, the clamping member 300 has a connecting portion 310 and an elastic clamping portion 320, and the connecting portion 310 is fixedly connected to the filling frame 100, so the installation of the clamping member 300 can be realized. On the basis of the installation of the clamping member 300, the elastic clamping portion 320 is arranged close to the orifice of the through hole 110. Therefore, in the use state, the elastic clamping portion 320 can be clamped with the clamping groove 211, so that the filling needle 200 is fixed in the through hole 110. Since the filling needle 200 has a tendency to slide upward along the through hole 110 under the clamping action of the elastic clamping portion 320, during the production process, when the medicine bottle is misaligned or buckled, the external force generated can cause the elastic clamping portion 320 to slide out of the clamping groove 211, so that the filling needle 200 moves upward along the through hole 110, which can reduce the impact force on the filling needle 200. Therefore, needle breakage, needle bending, and needle blockage (glass fragments) can be fundamentally avoided, and the structure is simple without dead corners, easy to clean and high-temperature sterilize, greatly improving the product quality and output.

[0045] In an embodiment of the present application, the connecting portion 310 is arranged on the first side wall of the filling frame 100 and is fixed relative to it; the elastic clamping portion 320 abuts against or protrudes above the top surface of the filling frame 100, and at least partially extends to the upper orifice edge of the through hole 110. Such a setting can facilitate the installation of the clamping member 300. During installation, the clamping member 300 can be placed at the corresponding position and then installed and fixed.

[0046] In this embodiment, referring to Figure 4, the elastic clamping portion 320 is configured to have an elastic bent open-loop structure, and the connecting portion 310 is configured to have a toroidal structure. This structure is simple and easy to install.

[0047] Combined with Figure 3 and Figure 4 , a fixing hole (not shown in the drawings) is provided on the first side wall of the filling rack 100; a fastener 400 is passed through between the connecting portion 310 and the fixing hole, and the fastener 400 is screwed into the fixing hole so that the connecting portion 310 is clamped between the first side wall of the filling rack 100 and the fastener 400, thereby realizing the installation and fixation of the positioning member 300.

[0048] In this embodiment, the fastener 400 can be a fastening screw.

[0049] Referring to Figure 5 , the filling needle 200 includes a main pipe section 210, a rubber tube joint 220 communicating with the upper part of the main pipe section 210, and a needle tube 230 communicating with the lower end of the main pipe section 210; a positioning groove 211 is provided on the main pipe section 210.

[0050] Exemplarily, the positioning groove 211 is configured as an annular groove provided on the peripheral wall of the filling needle 200.

[0051] Specifically, there is a clearance fit between the main pipe section 210 and the through hole 110. The through hole 110 is 20 microns larger than the main pipe section 210. The main pipe section 210 can slide up and down freely within the through hole 110; the filling needle 200 is inserted into the through hole 110 and is clamped into the positioning groove 211 by the elastic clamping portion 320 of the positioning member 300 and fixed on the filling needle rack; the elastic force of the positioning member 300 can not only fix the filling needle 200 on the filling rack 100 for normal operation, but also pop out of the positioning groove 211 when an external force is applied, allowing the filling needle 200 to slide upward, reducing the impact on the filling needle 200, and achieving the purpose of protecting the filling needle 200 and solving the problem of broken bottles.

[0052] In this embodiment, a side opening (not shown in the drawings) is provided on the second side wall. The side opening is perpendicular to and communicates with the through hole 110, so that the filling needle 200 can slide out from the side opening, facilitating the disassembly and assembly of the filling needle 200.

[0053] Referring to Figure 3 , a plurality of through holes 110 are provided, and the plurality of through holes 110 are arranged at intervals along the length direction of the filling rack 100; each through hole 110 corresponds to a positioning member 300. With this arrangement, multiple reagent bottles can be filled at one time, improving the filling efficiency.

[0054] This embodiment also provides a filling device, including the aforementioned filling needle assembly for vials, to achieve automatic filling, save manpower, and further improve the filling efficiency.

[0055] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present invention.
