Abstract
A quick coupler structure includes a male and a female coupler. The male coupler internally receives a fixed valve core surrounded by a spring and a connecting tube for connecting to a coupling platform at an upper part of the female coupler. The connecting tube is externally provided with sealing members to enhance airtight connection with the male coupler. The coupling platform defines a central thru-hole with a movable valve received therein to normally close it. When the fixed valve core is caused to expose from the connecting tube, it pushes the movable valve out of the central thru-hole to open the latter, allowing the male and the female coupler to communicate with each other. The sealing member won't be turned or loosened by a shearing force when the male and the female coupler are assembled or disassembled, giving the quick coupler structure upgraded air-tightness, pressure resistance and coupling reliability.
