Therefore, they should not be construed as limitations on this utility model.

[0028] like Figures 1-6 As shown, this utility model provides a technical solution: a highly reliable concealed fire sprinkler head, including a shell 1, a concealment component 2, a sprinkler component 3, etc. The sprinkler head can be concealed by the cooperation of the concealment component 2 and the sprinkler component 3, and the glass bottle can be easily replaced. It can be used for fire extinguishing operations. The concealment component 2 is set at the bottom of the shell 1, and the sprinkler component 3 is set inside the shell 1.

[0029] like Figure 1-6As shown in the embodiment of this application, multiple fixing cylinders 202 are located on the inner side of the bottom end of the outer shell 1. Fixing posts 204 are provided on the inner wall of the fixing cylinders 202. A fixing ring 209 is provided on the outer wall of the middle part of the fixing post 204. An annular groove adapted to the fixing ring 209 is provided on the inner wall of the fixing cylinders 202. A vertical plate 206 is provided at the bottom end of the fixing cylinders 202. The vertical plate 206 penetrates the vertical groove 207 on the chassis 201 to the circular groove 208. Multiple water-dividing grooves 203 are provided on the upper surface of the chassis 201. Multiple heat-conducting rods 205 are provided at the top end of the chassis 201. Limiting plates 210 are provided on both sides of the heat-conducting rods 205. One side of the limiting plate 210 is located on the inner wall of the outer shell 1, and one end of the heat-conducting rod 205 is located on the outer wall of the glass tube 304. Specifically, when performing concealed operation on the splash plate 301, it is necessary to use... To support the chassis 201, a fixing post 204 is fixedly installed on the inner side of the bottom end of the outer shell 1, and a fixing ring 209 is set on the fixing post 204 to limit the fixing cylinder 202. When installing the chassis 201, the vertical plate 206 passes through the vertical groove 207 on the chassis 201, so that the chassis 201 contacts the bottom end of the outer shell 1. Then, the vertical plate 206 is rotated in the circular groove 208. The vertical plate 206 is rotated so that the vertical plate 206 is perpendicular to the vertical groove 207, so that the chassis 201 can be fixed on the outer shell 1. When a fire occurs, the melting point of the vertical plate 206 is reached first. When the vertical plate 206 is melted, the chassis 201 falls off, thereby losing support for the splash plate 301. Then the glass tube 304 breaks, and fire water is sprayed out to extinguish the fire.

[0030] like Figure 1-6 As shown in the embodiment of this application, a water distribution groove 203 is provided on the chassis 201, thereby allowing the splash plate 301 to be replaced by the chassis 201. The movable rod 305 is fixed to the chassis 201, and a heat-conducting rod 205 is provided on the chassis 201. The melting point of the vertical plate 206 is set slightly higher than that of the glass tube 304. When the chassis 201 is heated, heat is transferred to the glass tube 304 via the heat-conducting rod 205, thereby causing the glass tube 304 to... When the glass tube 304 breaks, the vertical plate 206 on the chassis 201 begins to melt gradually. At this time, some fire water has already flowed out from the water distribution channel 203. When the melting point of the vertical plate 206 is reached, the chassis 201 falls, and the water spraying area of ​​the fire water will be further expanded. This avoids the need to conduct heat to the glass tube 304 when the melting point of the vertical plate 206 is lower than that of the glass tube 304, ensuring that fire extinguishing operations can be carried out the moment the chassis 201 falls off.

[0031] like Figure 1-6As shown in the embodiment of this application, a fixing block 102 is provided at the top center of the outer shell 1, a threaded pipe 101 is provided on the inner wall of the fixing block 102, and a support seat 103 is provided at the bottom of the fixing block 102. Specifically, by setting the threaded pipe 101 to cooperate with the water inlet pipe, fire water will enter the threaded pipe 101 through the water inlet pipe. The fixing block 102 is fixedly connected to the threaded pipe 101 to provide an installation environment for the threaded pipe 101. The outer wall of the fixing block 102 is provided with the outer shell 1, and the support seat 103 at the bottom of the fixing block 102 is used to provide support for the outer shell 1. The support seat 103 has a round hole adapted to the threaded pipe 101. The support seat 103 is used to provide an installation environment for the piston 303. The piston 303 is used to intercept the fire water and control the switch of the fire water.

[0032] like Figure 1-6 As shown in the embodiment of this application, a piston 303 is located inside the bottom end of the support base 103. A glass tube 304 is provided at the bottom end of the piston 303. A load-bearing rod 308 is provided at the bottom end of the glass tube 304. A splash plate 301 is provided on the outer wall of the load-bearing rod 308. Multiple supports 302 are provided at the bottom end of the support base 103. The other end of the supports 302 is connected by an annular sleeve 307. The annular sleeve 307 is provided on the outer wall of the load-bearing rod 308. A movable rod 305 is provided inside the supports 302. A spring 306 is provided on the outer wall of the movable rod 305. Specifically, when the ambient temperature rises, the glass tube 304... The heat-sensitive liquid inside the glass tube 304 will expand. Once the temperature reaches a certain limit, the expansion of the heat-sensitive liquid will cause the glass tube 304 to burst, thereby opening the piston 303. Finally, the fire-fighting water in the pressure tube will gush out. When the columnar water flows onto the splash plate 301, the water will splash in all directions to extinguish the fire. It is worth mentioning that the color of the glass tube 304 containing the heat-sensitive liquid is not fixed. Different colors indicate different types of liquids, and their expansion critical points are also different. In daily life, we can install glass tubes 304 of different colors according to the needs of the environment.

[0033] like Figure 1-6As shown in the embodiment of this application, a load-bearing rod 308 is provided at the bottom of the glass tube 304 to support the glass tube 304. The load-bearing rod 308 and the splash plate 301 can be movably connected. Under the action of the base plate 201, the splash plate 301 holds the glass tube 304 against it, thereby fixing it. When the glass tube 304 needs to be replaced, the base plate 201 is removed, and the splash plate 301 will be ejected a certain distance under the action of the spring 306. When the glass tube 304 is fixed, the spring 306 is in a compressed state. When the splash plate 301 falls, the movable rod 305 will move synchronously. The top of the movable rod 305 is provided with a protrusion to limit the displacement distance of the splash plate 301. The bracket 302 is fixed on the support base 103 to provide an installation environment for the movable rod 305. The load-bearing rod 308 has a structure that is narrow at the bottom and wide at the top. The splash plate 301 is on The round hole is adapted to the narrow part of the load-bearing rod 308, while the annular sleeve 307 is adapted to the wide part of the load-bearing rod 308. In the event of a fire, when the splash plate 301 falls under the action of the spring 306, the splash plate 301 will drive the load-bearing rod 308 to fall, and the wide part of the load-bearing rod 308 will be stuck inside the splash plate 301. At this time, the glass tube 304 is in an active state. Therefore, the glass tube 304 does not need to reach its melting point to fall synchronously under the action of the load-bearing rod 308, thereby losing control of the piston 303. The fire water will flow down and fall on the splash plate 301 to extinguish the fire. If there is concern about the lack of sensitivity to fire, the melting point of the vertical plate 206 can be set to be the same as that of the glass tube 304. In this way, when the vertical plate 206 melts and causes the base plate 201 to fall, the glass tube 304 can be misaligned, thereby extinguishing the fire, and it is also convenient to replace the glass tube 304.

[0034] like Figure 1-6 As shown in the embodiment of this application, the load-bearing rod 308 and the splash plate 301 can be configured as a threaded connection. In this state, the protrusion at the top of the movable rod 305 at the top of the splash plate 301 is in contact with the bracket 302. When the base 201 falls due to the melting of the vertical plate 206, the splash plate 301 will not fall. At this time, the melting point of the vertical plate 206 is lower than that of the glass tube 304. After the vertical plate 206 melts, it will begin to break the glass tube 304. When the melting point of the glass tube 304 is reached, the glass tube 304 will... When the piston 303 breaks, it loses its support, and the fire water will flow down and fall onto the splash plate 301 for dispersion, thereby extinguishing the fire. When the glass tube 304 needs to be replaced, the threaded part of the load-bearing rod 308 can be disengaged from the splash plate 301 by turning the load-bearing rod 308. Then the load-bearing rod 308 will fall down, thereby releasing the support for the glass tube 304, and the glass tube 304 can be replaced. Under this connection, the movable rod 305 will not move, and the length of the movable rod 305 is just right for the distance from the splash plate 301 to the bracket 302.

[0035] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended embodiments and their equivalents.
