The invention discloses a water tank injection quick connector structure which comprises a connecting short pipe, a connecting female head and a connecting male head, and the connecting male head and the connecting female head form a quick connector structure. A circle of clamping groove is formed in the periphery of the connecting female head, and a female head seal is arranged on the inner periphery of the clamping groove; a clamping head matched with the clamping groove is arranged on the periphery of the connecting male head, and a male head seal is arranged on the inner periphery of the connecting male head; the female head sealing ring is provided with an expansion part, the expansion part expands outwards in the radial direction after pressure water is filled, the lock pin structure corresponds to the expansion part in position, an action part in the lock pin structure is driven by the expansion part to stretch out of the outer wall of the female head sealing part in the radial direction, and an inner concave groove is formed in the inner wall of the clamping head. The expansion part is arranged on the side face of the female head sealing ring, and the lock pin structure is pushed to move through radial expansion movement of the expansion part after water filling, so that the connecting female head and the connecting male head are locked, and irrelevant personnel are prevented from dismantling a water supply pipe in the pipeline water passing process.
本发明公开了一种水舱注入快速接头的结构,包括连接短管、连接母头、连接公头,连接公头与连接母头组成快速接头结构;连接母头的外周设有一圈卡接槽,卡接槽内周设有母头密封;连接公头外周设有与卡接槽相配合的卡接头,连接公头内周设有公头密封;母头密封圈上设有膨胀部,压力水充入后膨胀部沿径向向外侧膨胀,锁销结构与膨胀部位置相对应,锁销结构内的动作部件受膨胀部的驱动沿径向伸出母头密封部的外壁,卡接头内壁设有内陷槽。本发明在母头密封圈侧面设置有膨胀部,利用充水后膨胀部的径向扩张移动推动锁销结构移动,从而将连接母头与连接公头实现锁定,从而避免在管路通水的过程中无关人员拆除供水管。
