Anti-loosening buckle and hose connector using same
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.
