摘要 |
PROBLEM TO BE SOLVED: To enable switching to low water pressure and low water quantity for daily use in watering, and to easily and simply connect a fire extinguishing nozzle of the present invention with other fire hose without need for disconnecting the nozzle from a tip of a fire hose in the case where the length of the fire hose is not enough for fire fighting.SOLUTION: A fire extinguishing nozzle includes: an inner cylinder 1; an outer cylinder 2 threadedly engaged with an outer circumference of a tip of the inner cylinder 1 so as to be rotatable and movable in a front-back direction, the outer cylinder having a valve part 2a formed on an inner circumference of the tip; a spindle 4 provided inward of the tip of the inner cylinder 1, the spindle having a deflector 3 at the tip that abuts and separates from the valve part 2a of the outer cylinder 2; and a cylindrical metal receiving tool 5 that is fitted to an outer circumference of a base portion of the inner cylinder 1 and that is connected to a tip of a fire hose A. By moving the outer cylinder 2 frontward and backward, the fire extinguishing nozzle can switch between opening state and stopping state of water flows or jet-type or shower-type of water flows. The fire extinguishing nozzle also includes a flow adjustment mechanism 6 and a male-type metal tool 8 that is detachably connectable.SELECTED DRAWING: Figure 2 |
