FIG. 2 is a partial sectional view of the nucleic acid test tube with easy handling according to this embodiment.
Detailed Description
The nucleic acid test tube of the present invention will be further described with reference to FIGS. 1 to 2.
A nucleic acid test tube convenient to operate comprises a collection tube 1 and a spiral cover 2 assembled on the collection tube 1, and is characterized in that: the screw cap 2 comprises a connecting sleeve 23 and a flip cap 21. The side wall of the nozzle of the collecting pipe 1 is provided with an external thread, the inner wall of the connecting sleeve 23 is provided with an internal thread, and the connecting sleeve 23 is assembled on the nozzle of the collecting pipe 1 through a thread structure. The upper end of the connecting sleeve 23 is formed with a ring plate 232 extending towards the center of the connecting sleeve 23, the center of the ring plate 232 is provided with an upper tube body 234 extending upwards, and the central hole of the upper tube body 234 is used for placing a nucleic acid swab into the collection tube 1. The flip cover 21 is connected to the connecting sleeve 23 by a connecting piece 22, and the connecting piece 22 is a flexible sheet, so that the flip cover 21 can be flipped with respect to the connecting sleeve 23. On the inner wall of the flip cover 21 there is an outer sealing sleeve 213 and an inner sealing sleeve 212 which can enter the upper tube body 234 to seal the upper tube body 234. When the flip cover 21 is turned upwards and covered on the connecting sleeve 23, the inner sealing sleeve 212 is inserted into the upper tube 234 to achieve the sealing effect.
Specifically, have interior step 2342 on the inner wall of upper pipe body 234, this interior step 2342's step face down, have on the lateral wall of interior seal cover 212 with interior step 2342 complex location rib 2121. After the inner sealing sleeve 212 enters the upper pipe body 234, the positioning rib can be clamped and limited on the step surface of the inner step 2342 so as to play a positioning effect on the flip cover 21 and avoid the problem that the inner sealing sleeve 212 is accidentally separated from the upper pipe body 234.
The inner wall of the upper pipe 234 is inclined 2341. That is, an inclined section is provided on the inner wall of the upper end of the upper tube 234, and the diameter of the inclined section is gradually reduced from top to bottom. Under this structure can play the extrusion effect to the interior seal cover 212 that stretches into upper tube body 234 to promote sealed effect.
