Example 2: based on the technical scheme of the embodiment 1: the decorative cover 5 may also be composed of a single decorative sheet 53 meltable when being heated, notches 51 movably connected with the back-type supporting frames 4 are respectively arranged on two side edges of the decorative sheet 53, the other end of each back-type supporting frame 4 penetrates through the notch 51 of the decorative sheet 53, and the melting point of the single decorative sheet 53 meltable when being heated is: 68. and the temperature is 93-93 ℃.
The basic principle of the utility model is as follows:
1. the installation process of the flush type fire-fighting sprinkler comprises the following steps: as shown in figure 1, the state is the initial state of each element, the fire sprinkler is firstly placed upside down for assembly during installation, and the condition that the opening and positioning structure is unstable and can fall off at any time to influence the assembly is avoided. When the shower head is placed upside down, the shower plug 3 blocks the water outlet 84 of the water inlet pipe 81 under the action of the guide rod 36. And due to the gravity, the sealing element 33 on the spray plug 3 is attached to the end face of the water outlet 84 of the water inlet pipe 81, at this time, an internal hexagonal wrench is used to extend into the internal hexagonal groove 23 of the screw 22 from the middle through hole 52 of the decorative plate 53 to rotate the screw 22, the screw 22 supports the sealing element 33 on the attached end face of the water inlet pipe 81 more tightly through a splash plate 35 but is not yet locked, because the positioning plate 2 cannot rotate in the inner cavity 66 of the fire nozzle 6 due to the fastening of the back-type support frame 4 on the positioning plate 2 and the fastening groove 63 on the inner cavity 66 of the fire nozzle 6, the rotation of the screw 22 will make the positioning plate 2 slide in the direction away from the spray plug 3 along the inner cavity 66 of the fire nozzle 6, the positioning plate 2 will support the first support rod 41 on the back-type support frame 4 through the first mounting groove 21 on the positioning plate 2 so that the first support rod 41 is in an inclined state due to the rotation, the rotation of the back-type support frame 4 will make the decorative plate 4 support rod 41 on the back-type support frame 4 support rod in an inclined state along with the opening of the decorative plate 53, and the decorative plate 53 will not affect the connection of the second decorative plate structure of the decorative plate 53 and the second support rod 42, so that the decorative plate 53 and the decorative plate 4 are connected to the second decorative plate 42. According to the principle of force action and reaction force, the reaction force from the decorative sheet 53 and the buckling groove 63 on the inner wall of the fire fighting nozzle 6 transmits force to act on the screw rod 22 through the back type supporting frame 4 and the positioning plate 2, so that the screw rod 22 can better lock and seal the sealing element 33 on the water outlet 84 of the water inlet pipe 81 through the water splashing plate 35 and the spraying plug 3, finally, the fire fighting sprinkler is inverted and then is installed with an external water pipe through the threaded connector 82 of the water inlet pipe 81 of the fire fighting nozzle 6, and finally, the state shown in fig. 2 is formed.
2. The fire extinguishing principle of the flush type fire-fighting sprinkler is as follows: after the installation is completed, when a fire occurs in a house and the decoration cover 5 is fused to a melting point or the two decoration sheets 53 are separated due to melting of a fusible welding point on the decoration cover 5, the back support frame 4 supporting the decoration cover 5 and the positioning plate 2 abutting against the back support frame 4 both fall due to instability, the shower plug 3 slides downward due to self weight and water pressure from the water inlet pipe 81, the guide rods 36 arranged on both sides of the shower tray 35 also slide downward until the limit blocks 38 arranged on the upper end of the guide rods 36 contact with the upper end surface 68 of the polygonal limit boss 61, the plug 3 and the shower tray 35 stop sliding downward, and water from the water inlet pipe 81 impacts the shower tray 35 to increase the spray area of the water, thereby achieving a better fire extinguishing effect.
Having shown and described the basic principles and essential features of the invention and its advantages, it will be understood by those skilled in the art that the present invention is not limited by the embodiments described above, which are merely illustrative of the principles of the invention, but is susceptible to various changes and modifications without departing from the spirit and scope of the invention, all of which are intended to be covered by the appended claims and their equivalents.
