The present invention relates to a fire extinguisher which is formed inside a body part of a fire extinguisher gun to form a plurality of through holes in a diaphragm to which a deflector is coupled so that turbulence is not generated when the fire extinguishing water passes through the through- 1 to 3, the body 50 includes a body 100 having a substantially cylindrical shape and provided with a deflector 120 on the inner side thereof, And a cover unit 200 installed to move forward and backward.

In more detail, the body 100 includes a body member 110 formed in a cylindrical shape and having a flow path formed therein, a diaphragm 112 formed at an inner central portion of the body member 110, A plurality of through holes 112a are formed in the diaphragm 112 so that the water for fire fighting can pass through.

At this time, when the fire-fighting water passes through the partition plate 112 through the through-hole 112a formed in the partition plate 112, the flow of the water for fire fighting is arranged inside the body member 110, so that turbulence is not generated, As shown in Fig.

A deflector 120 is coupled to the inner side of the body member 110 so that the fire extinguishing water can be diffused. The deflector 120 is coupled to the coupling hole 112b formed at the center of the diaphragm 112, And a disk 124 which is provided in front of the coupling shaft 122 and is located at the front end of the body member 110. The water 124 is diffused by the disk 124. [

Here, the inner circumferential surface of the body member 110 is narrowed toward the front and then expanded so that the water is dispersed at the front end of the body member 110.

The cover unit 200 is coupled to the outer side of the body unit 100 such that the cover unit 200 is moved forward and backward from the outer side of the body unit 100. The cover unit 200 is formed in a cylindrical shape, A cover ring 210 coupled to the front outside of the cover member 210 and a cover ring 220 coupled to the front of the cover member 210; And a handle 240 coupled to the outer side of the covering 230 by a fastening member 242.

At this time, the cover member 210 is coupled to the front of the body member 110, and the protection ring 220 is coupled to the outside of the cover member 210 to protect the fire- It is made of elastic material.

The cover ring 230 is coupled to a rear portion of the cover member 210 to prevent the protection ring 220 from being detached.

In addition, a plurality of protrusions 216 are formed in front of the cover member 210 to form a fine water film when the fire-fighting water is radiated, so that the fire can be suppressed more effectively.

That is, according to the firebox 50 constructed as described above, even when the water for fire exiting the inside of the body member 110 is diffused outward by the flow path formed inside the body member 110 and the disk 124 4, so that a wide range of fire can be suppressed.

A spiral guide groove 114 is formed on the outer circumferential surface of the body member 110 and a guide pin 212 is provided on the cover member 210 to be positioned in the guide groove 114.

The guide pin 212 provided on the cover member 210 is inserted into the guide groove portion 114 of the body member 110. Thus, So that the cover part 200 moves toward the front of the body part 100. As shown in FIG.

5, a cylindrical auxiliary passage is formed in front of the body part 100 by the inner circumferential surface of the cover part 200, so that the water-repelling water flows along the inner peripheral surface of the cover part 200 in the straight- So that the spraying method can be changed.

At this time, a plurality of fixing grooves 116 are formed in the longitudinal direction on the outer circumferential surface of the body member 110. A ball plunger 214 is coupled to the cover member 210 to be positioned in the fixing groove 116, So that the position of the cover part 200 moved to the second position can be fixed.

That is, when the guide pin 212 is moved along the guide groove portion 114 of the body member 110 by holding the handle 240 and rotating the cover portion 200, A ball (not shown) resiliently supported by a spring (not shown) is detached from the fixed groove portion 116 where it is initially positioned and is slid along the outer circumferential surface of the body member 110 to fix the cover portion 200 at a predetermined position The ball (not shown) of the ball plunger 214 is positioned in the fixing groove portion 116 located in front of the body member 110 to fix the cover portion 200 at a predetermined position of the body portion 100 It is possible to prevent the cover portion 200 from moving backward due to the water pressure of the water to be sprayed.

Meanwhile, a nut part 300 to which a fire hose 10 is connected is coupled to the rear of the body part 100 to supply water for fire fighting.

The operation of the fire extinguisher window 50 according to the above construction will be described as follows.

First, the fire hose 10 is connected to the rear end of the body part 100 using the nut part 300, and the water for fire fighting is supplied.

In addition, by the flow path formed inside the body member 110 and the disk 124 of the deflector 120, the fire-fighting water is radiated outwardly to be radiated, thereby suppressing a wide range of fire.

Next, the cover part 200 is moved forward to form an auxiliary flow path in front of the body part 100, so that the fire fighting water can be straightened to change the injection method.

The guide pin 212 is moved along the guide groove portion 114 of the body member 110 by rotating the cover portion 200 while holding the handle 240 provided in the cover portion 200, The ball plunger 214 mounted on the body member 110 moves along the outer circumferential surface of the body member 110 and the ball plunger 214 is moved in a direction The cover portion 200 is fixed to the front of the body portion 100 and the auxiliary flow path is formed in front of the body portion 100. Thus, .

According to the fire fighting nozzle 50 of the present invention, a plurality of through holes 112a are formed in the partition plate 112, which is formed inside the body part 100 of the fire fighting nozzle 50 and to which the deflector 120 is coupled. The turbulence is not generated when the water for fire fighting water passes through the through hole 112a of the partition plate 112 so that the fire fighting water can be sprayed smoothly and the guide groove 115 is formed on the outer peripheral surface of the body member 110 of the body part 100, A guide pin 212 corresponding to the guide groove 114 is fixed to the cover member 210 of the cover part 200 coupled to the outside of the body part 100, The ball plunger 214 corresponding to the groove portion 116 is provided so that the cover portion 200 can be moved forward and backward from the outside of the body portion 100 so that the spraying method of spinning or direct spraying can be selectively controlled Respectively.
