Abstract

The invention discloses a flush-resistant pneumatic quick-change connector and an air entraining plug in matched use thereof, wherein the flush-resistant pneumatic quick-change connector comprises an air inlet connecting sleeve, an air inlet seal ring, a seal check ring, a valve core, a slide sleeve spring, a disassembly slide sleeve, a locking steel ball, a protective shaft sleeve, an inner slide sleeve with a shoulder, an air outlet seal ring, an inner sleeve spring, a valve core spring, a radial sleeve and a positioning ball. The three main parts, namely the air inlet connecting sleeve, the valve core and a mobile slide sleeve, have the advantages of simple structure and good machining process; the machining can be finished by adopting a conventional low-cost mechanical machining method; the structure of the air entraining plug is extremely simple, and the machining cost is low; the flush-resistant pneumatic quick-change connector and the air entraining plug are in matched use, have the quick-change function and can prevent the flush phenomenon from occurring when the air entraining plug is detached; and all the functions of the safety pneumatic quick-change connector in the Chinese patent CN201152427Y can be realized, and the cost is 30-50% lower than that of the safety pneumatic quick-change connector.
