Description

Technical Field

[0001] The utility model belongs to the technical field of medicine production, and in particular relates to a quick-disassembled and repeatedly positioned needle filling seat. Background Art

[0002] The existing ampoule filling machine needle rack has a gap of only 1mm between the needle and the bottle wall, which is easy to get stuck on the wall and affect the wire drawing effect. In order to adapt to the position requirements of the ampoule bottle, a single needle is designed to be adjustable. The needle is made into a single adjustable structure, which solves the problem of the needle installation position, but faces a new problem: the number of disassembly and installation is large, which makes the work efficiency very low.

[0003] In addition, the filling needle is tightened with a cylindrical screw. Since the filling needle and the needle holder are originally a clearance fit, the filling needle and the needle holder mounting hole are actually in line contact through the screw tightening, the positioning is inaccurate, the filling needle is tilted, the position repeatability is poor, and the positioning is poor after the filling needle is removed and reinstalled. There are also methods of using PEEK needle holders to make notches and filling needle clamps. The needle holder and the filling needle are interference fits, and the positioning is better, but there is a problem. The processing is not very good at controlling the interference amount. The processing interference amount is small, the filling needle is too loose, and it is easy to move. Especially for the hard tube connection of CIPSIP, it is not suitable, the interference amount is high, and the clamping is inconvenient. Summary of the invention

[0004] The utility model aims to provide a quick-disassembled and repeatedly positioned injection needle holder to solve the problems of low working efficiency and inconvenient clamping in the prior art.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a quick-detachable and repositionable needle filling seat, comprising a bracket and a needle holder assembly mounted on the bracket;

[0006] The needle holder assembly consists of a needle seat plate, multiple needle holders, an injection needle and a fastening screw; one end of the multiple needle holders is fixed on the needle seat plate, and the other end is penetrated from top to bottom with a socket for the injection needle to be inserted, and a threaded hole connected to the socket is opened at the end of the needle holder close to the socket, and the injection needle is inserted into the socket and fastened by the fastening screw; a positioning block is provided at the end of the needle seat plate away from the injection needle, and the positioning block matches the positioning seat set on the bracket.

[0007] Furthermore, the bracket includes a bottom plate, a vertical plate fixed on the bottom plate, and a connecting plate arranged on the vertical plate. The connecting plate is parallel to the bottom plate and is provided with a connecting hole.

[0008] Furthermore, the bracket is an L-structure, and its bottom plate is a rectangular structure.

[0009] Furthermore, the positioning seat is composed of a base and a positioning groove opened on the base, and the positioning block is inserted into the positioning groove.

[0010] Furthermore, the number of the needle holder assembly installed on the bracket is at least one.

[0011] Furthermore, the number of positioning seats arranged on the bracket is at least two.

[0012] Furthermore, the number of positioning blocks arranged on the needle seat plate is at least two.

[0013] Furthermore, the positioning block is in the shape of an isosceles triangle, and the positioning groove matching it is also in the shape of an isosceles triangle.

[0014] Furthermore, the socket is in a square shape, and the upper portion of the filling needle that is matched with the socket is also in a square shape.

[0015] Beneficial effects: The utility model modularly assembles the needle seat plate, the needle holder and the filling needle into a needle holder assembly, thereby realizing quick disassembly and quick replacement of the filling needle and improving assembly efficiency; by providing a square filling needle and a corresponding square socket, the filling needle can be prevented from moving, and clamping is convenient.
