Abstract
The utility model relates to the technical field of water guns, in particular to an inner straight flute and outer spiral flute water gun head installation structure, and aims at solving the problems that an existing water gun is too complex in installation structure of a gun head, troublesome, time-consuming and low-efficiency in loading marbles, toilsome in rotating a sleeve tube and hard in manufacturing water outlet holes in the gun head. An inner sleeve tube is disposed between the gun head and a rotating sleeve tube, and a straight flue on the inner sleeve tube is matched with a spiral flute on the rotatable sleeve tube. The rotatable sleeve tube is rotated to drive a deflector bar and then drive the gun head to do linear movement back and forth so as to adjust water outlet modes. The installation structure of the gun head of a water gun is simpler than that of a previous structure, does not need loading the marbles and improves production efficiency. The rotating sleeve tube only plays rotating and driving roles without bearing interior huge water pressure and rotation of the rotating sleeve tube is easier. The water outlet holes on the gun head are surrounding radial through holes along the circumference. Compared with axial through holes in a previous structure disposed in a limited round table-face of the gun head, the radial through holes are simpler and easier to machine.
