Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] like Figures 1 to 4 As shown, the present invention provides a fire extinguishing spraying device, including a spray head 1, and a connecting pipe 2 is provided on the rear side of the spray head 1;

[0027] A baffle 3 is fixedly connected to the front of the connecting pipe 2. A connecting sleeve 4 is fixedly connected to the front side of the baffle 3. The front side of the connecting sleeve 4 extends into the interior of the spray head 1 and contacts the inner wall of the spray head 1. A slot 5 is provided on both sides of the spray head 1. A sleeve 6 is movably connected to the interior of the slot 5 through a pin. The end of the sleeve 6 away from the slot 5 extends to the rear side of the baffle 3 and contacts the surface of the baffle 3. A limiting ring 7 is fitted on the surface of the spray head 1. The inner side of the limiting ring 7 contacts the surface of the sleeve 6. A support ring 8 located in front of the limiting ring 7 is fixedly connected to the surface of the spray head 1. Multiple support rods 9 are fixedly connected to the rear side of the support ring 8. The rear side of the support rods 9 passes through to the rear side of the limiting ring 7 and is slidably connected to the limiting ring 7. A rebounder 10 is fitted on the surface of the support rods 9. The rear side of the rebounder 10 is fixedly connected to the front side of the limiting ring 7. The front side of the rebounder 10 is fixedly connected to the rear side of the support ring 8.

[0028] refer to Figure 4 A transmission box 11 is fixedly connected to the top of the spray head 1. A moving block 12 is slidably connected to the rear side of the inner wall of the transmission box 11. Limiting grooves 13 are opened on both sides of the inner wall of the moving block 12. A connecting plate 14 is fixedly connected to the top of the moving block 12. The top of the connecting plate 14 extends through to the top of the transmission box 11 and is fixedly connected to a pull rod 15. The end of the pull rod 15 away from the connecting plate 14 is fixedly connected to the top of the limiting ring 7. Two push plates 16 are slidably connected to both sides inside the transmission box 11. A limiting block 17 is fixedly connected to the outer side of the push plate 16. The limiting block 17 is used in conjunction with the limiting groove 13. A pressing block 18 located in front of the limiting block 17 is fixedly connected to the outer side of the push plate 16. The outer side of the pressing block 18 extends through to the outside of the transmission box 11.

[0029] As a technical optimization of this utility model, by setting up a transmission box 11, a moving block 12, a limiting groove 13, a connecting plate 14, a pull rod 15, a push plate 16, a limiting block 17, and a pressing block 18, the limiting ring 7 can be pulled back and limited, thus avoiding the phenomenon of automatic rebound of the limiting ring 7.

[0030] refer to Figure 4Pull plates 19 are fixedly connected to both sides of the movable block 12. The outer side of the pull plate 19 extends through to the outside of the transmission box 11 and is slidably connected to the inner wall of the transmission box 11.

[0031] As a technical optimization of this utility model, by setting the pull plate 19, it is easier for the user to pull the moving block 12, thereby improving the user's comfort.

[0032] refer to Figure 4 The transmission box 11 has two guide rods 20 fixedly connected horizontally inside. The guide rods 20 pass through the push plate 16 and are slidably connected to the push plate 16.

[0033] As a technical optimization of this utility model, by setting the guide rod 20, the push plate 16 can be guided, thereby improving the stability of the push plate 16 when moving.

[0034] refer to Figure 4 A return spring 21 is sleeved on the surface of the guide rod 20, and both sides of the return spring 21 are fixedly connected to the side opposite to the push plate 16.

[0035] As a technical optimization of this utility model, by setting a reset spring 21, the push plate 16 can be moved outward automatically, which improves the stability of the push plate 16 during movement.

[0036] refer to Figure 2 A sealing gasket 22 is fixedly connected to the front side of the connecting sleeve 4, and the front of the sealing gasket 22 contacts the inner wall of the spray head 1.

[0037] As a technical optimization of this utility model, by setting a sealing gasket 22, the inner wall of the connecting sleeve 4 and the spray head 1 can be made to contact more tightly, preventing water from leaking out from the gap between the connecting sleeve 4 and the spray head 1.

[0038] refer to Figure 3 A friction pad 23 is fixedly connected to the front side of the inner wall of the sleeve 6, and the front side of the friction pad 23 contacts the rear side of the baffle 3.

[0039] As a technical optimization of this utility model, by setting the friction pad 23, the ferrule 6 can be pressed against the surface of the baffle 3, thereby increasing the contact area between the ferrule 6 and the baffle 3.

[0040] refer to Figure 3 A fixing block 24 is fixedly connected to the rear side of the support rod 9, and the front side of the fixing block 24 contacts the rear side of the limiting ring 7.

[0041] As a technical optimization of this utility model, by setting the fixing block 24, the limiting ring 7 can be limited to prevent the limiting ring 7 from detaching from the support rod 9.

[0042] refer to Figure 2 Multiple mounting blocks 25 are fixedly connected to the surface of the connecting sleeve 4. The end of the mounting block 25 away from the connecting sleeve 4 extends into the interior of the spray head 1 and slides in connection with the inner wall of the spray head 1.

[0043] As a technical optimization of this utility model, by setting the installation block 25, the connecting sleeve 4 can be limited, thus preventing the connecting sleeve 4 from rotating inside the spray head 1.

[0044] refer to Figure 4 An anti-slip groove 26 is provided on the outer side of the pressing block 18, and the anti-slip groove 26 is used in conjunction with the pressing block.

[0045] As a technical optimization of this utility model, by setting the anti-slip groove 26, it is easier for the user to press the pressing block 18, thus improving the user's comfort.

[0046] The working principle and usage process of this utility model are as follows: When in use, first press the pressing block 18 inward. The pressing block 18 drives the push plate 16 and the limiting block 17 to move inward. After moving to the extreme position, the moving block 12 is pulled forward by the pull plate 19. The moving block 12 drives the connecting plate 14 and the pull rod 15 to move forward. The pull rod 15 drives the limiting ring 7 to move forward, so that the limiting ring 7 is away from the sleeve 6. After moving to the extreme position, the moving block 12 is fitted onto the surface of the limiting block 17. After the fitting is completed, release the pressing block 18, so that the push plate 16 springs back outward, so that the limiting block 17 is completely inserted into the interior of the moving block 12 to limit the moving block 12. After the limiting is completed, flip the sleeve 6 forward. After flipping it into place, insert the connecting sleeve 4 into the interior of the spray head 1 to connect the spray head 1 with the connecting pipe 2. After the connection is completed, reverse the above operation so that the sleeve 6 limits and fixes the connecting pipe 2 on the surface of the baffle 3.

[0047] In summary, this fire-fighting sprinkler system, through the inclusion of a support ring 8, support rod 9, limiting ring 7, clamp 6, and baffle 3, enables the initial connection between the connecting pipe 2 and the sprinkler head 1, preventing the sprinkler head 1 from becoming loose during use. The inclusion of a transmission box 11, moving block 12, connecting plate 14, and pull rod 15 facilitates the forward movement of the limiting ring 7, preventing slippage when the user directly pulls it. The inclusion of a push plate 16, limiting block 17, and pressing block 18 limits the movement block 12, preventing it from automatically resetting. This system offers the advantage of efficient installation and fixation, addressing a design flaw in the sprinkler head – its rotating snap-fit ​​method for fixing it inside the water outlet pipe. This structure, in practical use, can easily cause the sprinkler head to detach if the user accidentally touches or rotates it, leading to sprinkler failure and significantly reducing the practicality and reliability of the sprinkler head.
