[0027] The spiral tube 11 is connected to the fire water supply pipeline and is provided with an internal thread. The outer wall of the spiral tube 11 is integrally formed with a hexagonal seat 18 for easy installation or removal.

[0028] The spiral tube 11 and the sealing tube 12 are both hollow structures, interconnected, and are welded or integrally formed; preferably, integrally formed.

[0029] The first sealing ring 24, the convex stopper 31 and the sealing tube 12 are connected in an integrally formed manner.

[0030] After the first sealing plug 22, the first spring 28 and the first guide rod 20 are installed inside the sealing tube 12, the first chassis 26 is finally fixedly installed. The first chassis 26 and the tube wall can be fixed by welding; or a notch can be opened on the tube wall outside the first chassis 26, and a limit clamp or a clamping plate can be used to achieve detachable fixation.

[0031] The first guide rod 20 slides back and forth in the first chassis 26, and the second guide rod 21 slides back and forth in the second chassis 27. The connection is achieved by setting a smooth surface or a sealed linear bearing.

[0032] The outer diameter of the first sealing plug 22 is smaller than the inner diameter of the sealing tube 12. When the first sealing plug 22 is separated from the first sealing ring 24, water flows through the gap between the first sealing plug 22 and the inner wall of the sealing tube 12 to form a passage. A through hole is provided on the first chassis 26, and the water flow inside the first sealing plug 22 is connected to the fire water supply.

[0033] After the second sealing plug 23, the second spring 29 and the second guide rod 21 are installed inside the water pipe 13, the second chassis 27 is finally fixedly installed. The second chassis 27 and the pipe wall can be fixed by welding; or a notch can be opened on the pipe wall outside the second chassis 27, and a limit clamp or a clamping plate can be used to achieve detachable fixation.

[0034] A distance is maintained between the second chassis 27 and the bottom plate of the water pipe 13, which is beneficial for the second guide rod 21 to slide and extend.

[0035] The outer diameter of the second sealing plug 23 is smaller than the inner diameter of the water pipe 13. When the second sealing plug 23 is separated from the second sealing ring 25, water flows through the gap between the second sealing plug 23 and the inner wall of the water pipe 13 to form a passage. A through hole is provided on the second bottom plate 27. When the heat-sensitive glass rod 15 is broken, the water flow inside the second sealing plug 23 is connected to the outside of the pipe body.

[0036] The edge of the water guide plate 14 extends upward to form a flange 19, which is tilted outward and has several slots at intervals. The water guide plate 14 has several air holes. When a fire occurs below the fire sprinkler, the temperature rises, and the hot air rises, which can quickly pass through the air holes and contact the thermosensitive glass rod 15, so that the thermosensitive glass rod 15 quickly senses the high temperature and quickly breaks to spray water to extinguish the fire, thereby improving the response speed of the fire sprinkler.

[0037] A flange 19 is arranged on the edge of the water guide plate 14 so as to be tilted upwards, and a plurality of slots are provided on the flange 19 at intervals. When fire-fighting water hits the water guide plate 14 from top to bottom, the water flow will spread upwards along with the tilted flange of the water guide plate 14, thereby increasing the coverage area of ​​the spread water flow and enhancing the fire-fighting effect.

[0038] The pressure ring 32 is arranged on the inner wall of the limiting ring 17, and the pressure ring 32 and the limiting ring 17 are integrally formed. When installed, the inner wall of the limiting ring 17 is close to the outer wall of the convex stop 31, and the inner wall of the pressure ring 32 is close to the outer wall of the water pipe 13. A third spring 30 is installed between the convex stop 31 and the pressure ring 32. A clamping ring 35 is installed on the outer periphery of the end of the water pipe 13 close to the limiting ring 17. The clamping ring 35 limits the sliding of the limiting ring 17 to prevent it from detaching from the water pipe 13 body.

[0039] The end surface of the pressing ring 32 relative to the clamping bead 34 is arranged in a slope shape, which is conducive to the pressing ring 32 to quickly squeeze the clamping bead 34 during the spring return process, so that the clamping bead 34 is located below the pressing ring 32.

[0040] Under normal conditions, the inner wall of the pressure ring 32 abuts against the clamping bead 34 , squeezing the clamping bead 34 to move toward the center of the tube body, and the portion of the clamping bead 34 that passes through the wall hole 33 is located inside the sealing tube 12 .

[0041] When the movable nozzle 39 and the sealing tube 12 are in a separated state, due to the action force of the spring, the first sealing plug 22 and the first sealing ring 24 are in a sealed state, and the second sealing plug 23 and the second sealing ring 25 are in a sealed state.

[0042] Working principle of this utility model:

[0043] When the movable nozzle 39 is docked with the sealing tube 12, it is necessary to hold the limit ring 17 and compress it toward the direction of the spiral tube 11. The pressure ring 32 moves with the displacement, so that the pressure ring 32 is away from the wall hole 33, and the extrusion restriction of the pressure ring 32 on the card bead 34 is released. At the same time, one end of the water pipe 13 of the movable nozzle 39 is inserted into the sealing tube 12, so that the blind hole 37 on the outer wall of the water pipe 13 corresponds to the position of the card bead 34, and the limit ring 17 is loosened. The third spring 30 is reset to make the pressure ring 32 move to the same radial direction of the wall hole 33, and the pressure ring 32 squeezes the card bead 34, so that the card bead 34 falls into the blind hole 37 on the outer wall of the water pipe 13, thereby fixing the movable nozzle 39.

[0044] During the above docking process, the opposite ends of the first guide rod 20 and the second guide rod 21 abut against each other and are displaced. The first guide rod 20 and the first sealing plug 22 move toward the direction of the spiral tube 11, and the first sealing plug 22 is separated from the first sealing ring 24; the second guide rod 21 and the second sealing plug 23 move toward the direction of the guide hole 36, and the second sealing plug 23 is separated from the second sealing ring 25; at this time, a connecting passage is formed inside the sealing tube 12 and the water pipe 13, and a seal is formed between the outer wall of the water pipe 13 and the inner wall of the sealing tube 12 through the sealing ring 38 to cut off the water flow.

[0045] When the movable nozzle 39 is separated from the sealing tube 12, the limit ring 17 is held and compressed and moved toward the direction of the spiral tube 11. The pressure ring 32 moves with the displacement, so that the pressure ring 32 moves away from the wall hole 33, and the squeezing restriction of the pressure ring 32 on the card bead 34 is released. The movable nozzle 39 is pulled out, and the card bead 34 is separated from the blind hole 37, and the restriction on the water pipe 13 is released. The limit ring 17 is loosened, and the limit ring 17 is reset under the action of the third spring 30, so that the pressure ring 32 is located in the same radial direction of the wall hole 33.

[0046] During the above separation process, the abutting first guide rod 20 and the second guide rod 21 are quickly separated, and the first spring 28 and the second spring 29 are quickly reset, so that the first sealing plug 22 and the first sealing ring 24 are closely matched, and the second sealing plug 23 and the second sealing ring 25 are closely matched, the water flow is disconnected, and the fire water output port is sealed in time.

[0047] The utility model uses the above embodiments to illustrate the technical concept of the utility model, but the utility model is not limited to the above embodiments, that is, it does not mean that the utility model must rely on the above embodiments to be implemented. Those skilled in the art should understand that the relevant improvements to the utility model fall within the protection scope and disclosure scope of the utility model.
