Abstract

The invention relates to a sealing cover which comprises a sealing cover body and a nozzle sealing hole formed in the sealing cover body and provided with a blind end. An annular sealing groove is formed in the periphery of the nozzle sealing hole, and an annular sealing boss extending into the groove is arranged on the side wall of the annular sealing groove. The sealing cover is good in sealingperformance and not prone to falling off.

Description

technical field [0001] The invention relates to a sealing device for a reagent box nozzle, in particular to a sealing cover. Background technique [0002] Kits are common experimental supplies in laboratories and are used to store reaction reagents. For the liquid reagent, the reagent box is provided with a liquid outlet to discharge it from the liquid storage tank in the reagent box. The liquid outlet of the kit is usually communicated with a tubular structure and a nozzle is arranged so as to control the liquid discharge. When the kit is storing liquid reagents, the nozzle is sealed by the sealing cap. The conventional sealing cap adopts a threaded design, and the sealing performance is not good. Unable to discharge fluid. Contents of the invention [0003] The object of the present invention is to provide a sealing cover with good sealing performance and not easy to fall off. [0004] The present invention adopts following technical scheme: [0005] A sealing cover...
