A SAFETY PLUG FOR A CONTAINER GENERATING HIGH PRESSURE FLUID

摘要

A safety plug for a container generating high pressure fluid comprises a locking body(3) and a safety cap(6), and a return element (7) mounted between the locking body and the safety cap. The locking body includes a locking mechanism(4) which is screwed airtightly into a hole of the container, and a buckle mechanism(5) which assembles with the locking mechanism. The buckle mechanism has a assembly tube(51) and a buckle ring(52) projecting from external peripheral surface of the assembly tube. When the cap body of the safety cap is pressed down and engage with the buckle ring, the cap boby(61) can rotate relative to the container togeth with the locking mechanism and releases from the hole. By the simple design that the buckle mechanism can snap on the safety cap and placement of the the return element, the safety plug may be manufactured and assembled more simply.
