Detailed Description
In order to make the technical means, the creation characteristics, the achievement purposes and the effects of the utility model easy to understand, the utility model is further described with the specific drawings.
Referring to fig. 1 and 2, a safety cap for disposable vacuum blood collection tube, includes cap body 1, and cap body 1 is the open hollow tubular structure in inside of both sides from top to bottom, is equipped with the annular strengthening rib 11 in round upper portion on the upper portion inner wall of cap body 1, is equipped with the annular strengthening rib 12 in round middle part on the middle part inner wall of cap body 1. The cap body 1 is a plastic cap made of plastic material. The upper annular reinforcing rib 11 and the middle annular reinforcing rib 12 are both made of plastic materials. The cap body 1, the upper annular bead 11 and the middle annular bead 12 are preferably formed integrally. The cap body 1, the upper annular reinforcing rib 11 and the middle annular reinforcing rib 12 can be manufactured integrally by adopting the existing injection molding process.
Still be equipped with at least a round of intra-annular wall strengthening rib 13 on the inner wall of cap body, intra-annular wall strengthening rib 13 is located middle part annular strengthening rib 12 below, and the smooth transition of intra-annular wall strengthening rib 13 and the inner wall junction of cap body 1. Preferably, the ring inner wall reinforcing ribs 13 are two circles, and the two circles of ring inner wall reinforcing ribs 13 are respectively arranged at preset distances from top to bottom. The protruding length of the upper ring inner wall reinforcing rib 13 is smaller than that of the lower ring inner wall reinforcing rib 13. When the cap body 1 is made of plastic, the inner wall reinforcing ribs 13 are also made of plastic and are integrally formed with the cap body 1.
