  • Patent number: 10082233
    Abstract: A hose quick coupling used to connect and buckle a nozzle includes a hose coupling main body and at least one buckle device. The buckle device includes a buckle handle pivotally connected to the hose coupling main body, an engaging pin movably disposed in the buckle handle, and a locking piece pivoted to the inner side of the buckle handle. When the engaging pin is biased by an elastic member, the upper end of the engaging pin extends out of the buckle handle and engages with the side wall of the hose coupling main body so that the buckle handle cannot be turned. Conversely, when the engaging pin is pulled to retract into the buckle handle, the engaging pin is disengaged and the buckle handle can be turned so that the nozzle can disengage from the hose coupling main body.

  • Patent number: 10001237
    Abstract: An anti-loosening buckle mounted at the hose connector body of a hose connector for locking an adapter mouthpiece includes a locking lever, a stop device, an interlocking member, and a position-limiting member. The locking lever is pivotally connected to the hose connector body and has a cam portion and an operating grip respectively disposed at two opposite ends. The stop device is slidably coupled to the operating grip. The interlocking member is coupled between the stop device and the hose connector body. The position-limiting member is mounted at the operating grip. When the locking lever is in the locking position, the bottom side of the stop device is abutted against the position-limiting member to lock the locking lever. When the position-limiting member is pulled away from the stop device, the locking lever is released from the constraint and can be freely biased.
