Detailed Description
The following describes embodiments of the present invention in detail with reference to the drawings, which are implemented on the premise of the technical solution of the present invention, and detailed embodiments and specific operation procedures are provided, but the scope of the present invention is not limited to the following embodiments.
As shown in figures 1-2, the needle tube mounting position inspection tool for chemiluminescence immune instrument comprises
The plug-in component 1 is movably clamped in a limiting hole of the reaction disc, the central axis of the plug-in component 1 is superposed with the central axis of the limiting hole, and the plug-in component 1 is provided with a connecting surface; and
the positioning piece 2 is horizontally arranged on the connecting surface, and the positioning piece 2 is provided with an upper positioning surface;
a positioning hole 3 which is arranged on the upper positioning surface, the diameter of the positioning hole is 1.4mm +/-0.1 mm, and the depth of the positioning hole is 2.0 mm; the positioning hole 3 and the limiting hole are eccentrically arranged, and the central distance between the positioning hole 3 and the limiting hole is 1.5mm +/-0.1 mm;
the length of the positioning piece 2 is greater than that of the limiting hole, so that the positioning piece 2 is clamped on the upper surface of the reaction disc, and the positioning piece 2 is prevented from falling off from the limiting hole.
