[0026] Embodiment 1

[0027] An automatic sprinkler head of a fire extinguishing system includes a frame body 1. One end of the frame body 1 is communicated with a water guide pipe 2. Threads are provided on the water guide pipe 2 for connecting with external devices. And a notch is provided on the outer side of the end of the water guide pipe 2 close to the frame body 1, which can be clamped with external devices to enhance the connection stability between the water guide pipe 2 and external devices. A splash plate 3 is provided at the other end of the frame body 1. The splash plate 3 is used to disperse the water flow transmitted by the water guide pipe 2. A support plate 4 is arranged inside the frame body 1. The support plate 4 can also play a role in dispersing the water flow transmitted by the water guide pipe 2. The support plate 4 is arranged between the water guide pipe 2 and the splash plate 3. The support plate 4 can be fixedly installed on the frame body 1 by welding. The surface of the support plate 4 has mounting holes 41. A seal 5 is provided at the opening where the water guide pipe 2 is communicated with the frame body 1. The seal 5 is used to block the water flow transmitted by the water guide pipe 2. A glass ball 6 is arranged between the seal 5 and the support plate 4. The glass ball 6 is used to support the seal 5 so that the seal 5 can block the water flow transmitted by the water guide pipe 2. When a fire breaks out, the glass ball 6 breaks, and the seal 5 loses the support of the glass ball 6. The water flow will wash the seal 5 away from the water outlet of the water guide pipe 2, so that water spraying for fire extinguishing can be carried out. One end of the glass ball 6 abuts against one end of the seal 5, and the other end of the glass ball 6 is embedded in the mounting hole 41. An adjusting member 7 is arranged on the surface of the support plate 4 away from the glass ball 6. One end of the adjusting member 7 is embedded in the mounting hole 41 and abuts against one end of the glass ball 6. Threads are provided on the surface of the side of the mounting hole 41 close to the adjusting member 7, and threads are provided on the surface of the adjusting member 7. The adjusting member 7 is threadedly connected with the mounting hole 41. The tightness of the abutment between the glass ball 6 and the seal 5 can be adjusted by screwing the adjusting member 7, so that the seal 5 can seal the water outlet of the water guide pipe 2 to prevent water leakage. At least one through hole 42 is provided on the surface of the support plate 4. The water flow can flow to the splash plate 3 through the through hole 42. By providing the support plate 4 and the adjusting member 7, the adjusting member 7 can control the glass ball 6 to quickly adjust the sealing degree between the seal 5 and the water guide pipe 2, and the support plate 4 can also play a role in water dispersion, improving the fire extinguishing efficiency. By providing the glass ball 6, when the air near the sprinkler head reaches a certain temperature, the glass ball 6 will break, so that the seal 5 loses support, and the water guide pipe 2 can spray water to extinguish the fire, achieving the purpose of automatic water spraying and fire extinguishing of the sprinkler head.

[0028] In this embodiment, a sealing ring 11 is arranged between the top of the frame body 1 and the seal 5. The sealing ring 11 is used to improve the sealing effect of the seal 5, so that the water guide pipe 2 will not leak water, improving the user experience. The sealing ring 11 can be a rubber ring.

[0029] In this embodiment, a recessed portion 12 is provided at the top of the frame body 1. The sealing ring 11 is arranged in the recessed portion 12. By providing the recessed portion 12, the sealing ring 11 is not easy to move, improving the sealing effect.

[0030] In this embodiment, an elastic member 13 is provided between the top of the frame body 1 and the seal member 5. The elastic member 13 is used to increase the detachment speed of the seal member 5 from the frame body 1, enabling the water conduit 2 to discharge water quickly, thereby improving the fire extinguishing efficiency. The elastic member 13 can be a spring.

[0031] In this embodiment, a groove 14 is provided at the top of the frame body 1. One end of the elastic member 13 is disposed in the groove 14, and the other end of the elastic member 13 abuts against the side surface of the seal member 5. By providing the groove 14, the position of the elastic member 13 is not likely to shift, so that the seal member 5 can be quickly ejected from the water outlet of the water conduit 2, enabling the water conduit 2 to discharge water quickly and improving the fire extinguishing efficiency.

[0032] In this embodiment, a sealing body 51 is provided at one end of the seal member 5 facing the water conduit 2. The end of the sealing body 51 away from the seal member 5 is embedded in the water conduit 2, and part of the side surface of the sealing body 51 abuts against the side surface of the water outlet of the water conduit 2. By providing the sealing body 51, the sealing effect of the seal member 5 can be improved.

[0033] In this embodiment, a fixing groove 52 is provided at one end of the seal member 5 facing the support plate 4. The end of the glass ball 6 away from the support plate 4 is embedded in the fixing groove 52. By providing the fixing groove 52, the end of the glass ball 6 in contact with the seal member 5 is not likely to shift, thus preventing the glass ball 6 from abnormally detaching from the seal member 5.

[0034] Embodiment 2

[0035] The difference between this embodiment and Embodiment 1 is that a protective layer 31 is provided on the surface of the splash plate 3. The protective layer 31 is used to prevent the splash plate 3 from being corroded and improve the service life of the splash plate 3. The protective layer 31 can be a paint layer or a galvanized layer.

[0036] In this embodiment, a water baffle 32 is provided on the side of the splash plate 3. The water baffle 32 is used to adjust the water flow direction. The water baffle 32 can be provided on the side close to the wall, so that the water flow will not spray towards the wall side, thereby maximizing the utilization of the water flow and improving the fire extinguishing efficiency.

[0037] In this embodiment, a fixing body 15 is provided at the top of the frame body 1. The side surface of the fixing body 15 abuts against the side surface of the seal member 5. By providing the fixing body 15, the seal member 5 is not likely to shift, improving the sealing effect of the seal member 5.

[0038] The other structures of this embodiment are the same as those of Embodiment 1 and will not be elaborated here.

[0039] Obviously, the utility model includes a frame body. One end of the frame body is communicated with a water guide pipe, and a water splashing plate is arranged at the other end of the frame body. A support plate is arranged inside the frame body, and the support plate is arranged between the water guide pipe and the water splashing plate. The surface of the support plate has mounting holes. A seal is arranged at the opening where the water guide pipe is communicated with the frame body. A glass ball is arranged between the seal and the support plate. One end of the glass ball abuts against one end of the seal, and the other end of the glass ball is embedded in the mounting hole. An adjusting member is arranged on the side of the support plate away from the glass ball. One end of the adjusting member is embedded in the mounting hole and abuts against one end of the glass ball. The surface of the support plate has at least one through hole. By arranging the support plate and the adjusting member, the utility model can control the glass ball through the adjusting member to quickly adjust the sealing degree between the seal and the water guide pipe, and the support plate can also play a role in water dispersion, improving the fire extinguishing efficiency.
