In FIG. 5, reference numeral 120b denotes a screw hole 174 formed at an upper portion of the tannery bolt 121 and the second coupling member 170 coupled to the screw hole 120a at the center of the compression plate 120. When engaging, it is a through hole in which the locking jig is inserted to prevent the compression plate 120 from turning.

Next, the operation and effects of the sprinkler head according to the embodiment of the present invention configured as described above will be described.

First, when a fire occurs in a state in which the sprinkler head 100 of the present invention is connected to a pipe (not shown) for supplying a fire extinguishing solution installed on the ceiling, the heat generated by the fire is first to third. It is rapidly absorbed by the heat sensing plates 191, 192, 193.

In other words, circular grooves 191b, 192b, and 193b are formed in the first to third heat sensing plates 191, 192, and 193 so as to quickly absorb heat by increasing the surface area. The periphery of the through hole 191a formed at the center thereof protrudes upward to maintain a predetermined distance from the second heat sensing plate 192, and the third heat sensing plate 193 can absorb heat rapidly and Since the periphery of the through hole 193a formed at the center thereof protrudes downward to maintain a predetermined distance from the second heat sensing plate 192, the first to third heat sensing plates 191, 192, and 193 are fired. The heat generated can be absorbed quickly.

As such, the heat absorbed by the first to third heat sensing plates 191, 192, and 193 may be formed of a composite material disposed between the third heat sensing plate 193 and the guide plate 130. Since no heat is transferred to the guide plate 130, the first to third heat sensing plates 191, 192, and 193 are rapidly heated to a high temperature, such as a melting temperature of the fuse 180, for example, 72 ° C. or The fuse 180 is melted by heating rapidly to a temperature of 105 ° C.

Accordingly, the first to third heat sensing plates 191, 192, and 193, the heat blocking ring 200, and the guide plate 130 fitted to the outer circumferential surface of the second coupling member 170 are along the second coupling member 170. It is pushed downward by the height of the fuse 180 melted.

As such, the first to third heat sensing plates 191, 192, 193, the thermal barrier ring 200, and the guide plate 130 are lowered by the height of the fuse 180 melted along the second coupling member 170. When it is pushed down, the compression plate 120 and the guide plate 130 is widened so that the stainless ball 120 is pushed into the receiving groove 124 formed in the lower portion of the compression plate 120.

Accordingly, the cone is disposed between the inner lower portion of the circular flange 164 of the first coupling member 160 and the support ring 144 of the extinguishing solution reflecting member 140 to push the extinguishing solution reflecting member 140 downward. The extinguishing solution reflective member 140 is pushed downward by the force of the spring 150.

At the same time, the tannery bolt 121, which is in contact with the lower part of the holder 142 of the extinguishing solution reflective member 140, is pushed downward by the holder 142, and the tannery bolt 121 and the compression plate ( 120, the stainless ball 120, the guide plate 130, the heat shield ring 200, the first to third heat sensing plates (191, 192, 193) and the second coupling means 170 is the cylindrical body 110 Since the support ring 144 of the extinguishing solution reflecting member 140 is caught on the circular flange 118 formed inside the lower portion of the cylindrical body 110, the first coupling member Fire extinguishing solution, for example, through the introduction pipe 162 of the 160, the extinguishing water is dropped in the concave groove 142b recessed recessed portion of the holder 142 of the extinguishing solution reflecting member 140 in a 360 degree direction It is ejected while being reflected, and also work with each other on the edge of the main body 141 of the fire extinguishing solution reflecting member 140 To the lower portion of the sprinkler head of the present invention it will be digested by the collision re-eve (141b) erected toward a gap caused by Obituaries upper also to rapidly extinguish the fire away.

In addition, if a fire does not occur, upper and lower surfaces of the spring washer 143 fitted on the holder 142 of the extinguishing solution reflective member 140 are covered with Teflon, so that the second coupling member 170 is The spring washer 143 coated with Teflon by the support force pushed up from the lower portion of the holder 142 of the digestion solution reflecting member 140 to the upper portion according to tightening is the first coupling member 160 Since the lower part of the inlet pipe is sealed, the extinguishing water does not leak.

Therefore, the sprinkler head of the present invention is installed on the ceiling of the room to quickly detect the heat generated in the event of a fire, and when a certain temperature at the time of fire, the fuse is melted to eject the fire extinguishing solution or powder for fire In addition to suppressing the fire early, it is possible to prevent the spread of fire, and the structure is simple, easy to assemble, and to reduce the manufacturing cost.

In the above description, although illustrated and described with reference to specific embodiments, the present invention is not limited to this, for example, by those of ordinary skill in the art without departing from the concept of the present invention Of course, the design can be changed in various ways.

As described above, according to the sprinkler head of the present invention, it is installed on the ceiling of the room to quickly detect the heat generated in the event of a fire, and when the temperature reaches a certain temperature at the time of the fire, the fuse melts and the extinguishing solution or the extinguishing powder It is possible to prevent the spread of the fire by ejecting, and the structure is simple, easy to assemble, and has an excellent effect of reducing the manufacturing cost.
