BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fire extinguishing nozzle, and more particularly, to a fire extinguishing nozzle capable of increasing water injection pressure in a process of transferring water from a fire hose to a water distribution pipe and discharging the water.

A fire extinguisher is a device attached to the front of a fire hose to easily spray water delivered from a fire hose of a fire truck to the point where the fire occurred.

Such a nozzle is usually formed of a metal material of a rigid material so as to flexibly respond to the pressure of water sprayed from the fire hose and to achieve the use thereof.

In order to more easily spray the water delivered from the fire hose to the point where the fire occurs, the above-mentioned nozzle may be configured to easily adjust the direction of spraying water, or various types of nozzle Is provided.

For example, in the conventional nozzle for fire fighting, there has been proposed a configuration in which water discharged through a nozzle can be easily discharged in the form of a direct spray or a spray, as in the document (1) There has been proposed a structure which can prevent the nozzle from being damaged while facilitating its use.

However, the conventional fire fighting nozzles have a similar structure for easily discharging the water delivered from the fire hose, which increases the pressure of the water passing through the inside of the nozzle and is difficult to discharge easily. There has been a problem that it is difficult to easily apply and improve due to the complicated configuration.

In particular, the purpose of adjusting the shape and direction of the water discharged through the nozzle was easy, but there was a difficult problem in increasing the pressure of the water discharged through the nozzle without complicated construction.
