In order to protect people's lives and property when a fire occurs, it is necessary to quickly detect and extinguish the fire. Therefore, fire sprinkler heads are usually used to spray water to quickly extinguish the fire, thereby reducing property damage and protecting people's lives.

[0003] However, traditional fire sprinkler heads are difficult to disassemble and use conveniently in actual use, which limits their application. Furthermore, the heat-sensitive glass tubes may be damaged during use, and different applications require different solutions. Traditional sprinkler heads are also difficult to replace easily, making them inconvenient and ineffective in use. Utility Model Content

[0004] The purpose of this invention is to provide a fire sprinkler head for rapid fire extinguishing, in order to solve the shortcomings of existing rapid fire sprinkler heads that are inconvenient to disassemble and replace the heat-sensitive glass tubes.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a fire sprinkler head for rapid fire extinguishing, including a wall and a water outlet;

[0006] A water outlet is provided at the bottom of the wall, a sprinkler head body is provided at the bottom of the wall, and a disassembly structure is provided at the top of the sprinkler head body;

[0007] The disassembly and assembly structure includes a snap-fit ​​groove, an internal groove, an inclined block, and a return spring. The snap-fit ​​groove is located on the top of the main body of the spray head, the internal groove is located inside the walls on both sides of the water outlet, and an inclined block is provided inside the internal groove. A return spring is fixed on one side of each inclined block.

[0008] A flow divider is provided below the main body of the spray head, and a fire extinguishing structure is provided at the top of the flow divider.

[0009] Preferably, the snap-fit ​​grooves are symmetrically distributed on both sides of the top of the spray head body, and the top of the spray head body is located inside the water outlet.

[0010] Preferably, the built-in grooves are symmetrically distributed inside the walls on both sides of the water outlet, and the side of the reset spring away from the inclined block is fixedly connected to one side inside the built-in groove.

[0011] Preferably, the inclined block is disposed inside the snap-fit ​​groove, and the inclined block and the spray head body form a snap-fit ​​structure through the snap-fit ​​groove.

[0012] Preferably, the fire extinguishing structure includes a threaded hole, a heat-sensitive glass tube, a threaded post, and a water plug. The threaded hole is opened at the top of the diversion plate, the heat-sensitive glass tube is disposed above the diversion plate, the bottom end of the heat-sensitive glass tube is fixed with a threaded post, and a water plug is disposed above the heat-sensitive glass tube.

[0015] The fire sprinkler head for rapid fire extinguishing provided by this utility model has the following advantages:

[0016] By incorporating a disassembly and assembly structure, the sprinkler head body is positioned during installation and use through a locking mechanism formed by the snap-fit ​​groove and the inclined block. During disassembly, the sprinkler head body is further squeezed into the water outlet, causing the inclined block to be squeezed and move into the interior groove. This facilitates the rotation of the sprinkler head body, moving the snap-fit ​​groove away from the inclined block and making it easier to remove the sprinkler head body. This achieves the purpose of facilitating the disassembly, assembly, and maintenance of the sprinkler head body.

[0017] By incorporating a fire extinguishing structure, the diversion plate is installed to the bottom of the sprinkler head body via a threaded connection, and the heat-sensitive glass tube is installed into the threaded hole via a threaded post. This pushes the water plug into the interior of the sprinkler head body, preventing water from flowing out. When the indoor temperature reaches a specified height, the liquid inside the heat-sensitive glass tube expands, causing it to rupture and allowing water to flow out easily. This achieves the purpose of facilitating automatic and rapid fire extinguishing and making it easy to disassemble and replace the heat-sensitive glass tube. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. 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.

[0025] Please see Figures 1-5 The present invention provides a fire sprinkler head for rapid fire extinguishing, comprising a wall 1 and a water outlet 2.

[0026] Reference Figure 2 and Figure 3 As shown, a water outlet 2 is provided at the bottom of the wall 1, and a sprinkler head body 3 is provided below the wall 1. A disassembly and assembly structure 4 is provided at the top of the sprinkler head body 3. The disassembly and assembly structure 4 includes a snap-fit ​​groove 401, an internal groove 402, an inclined block 403, and a return spring 404. The snap-fit ​​groove 401 is provided at the top of the sprinkler head body 3, and the internal groove 402 is provided inside the wall 1 on both sides of the water outlet 2. An inclined block 403 is provided inside the internal groove 402, and one side of the inclined block 403 is fixed. There is a return spring 404, and the snap-fit ​​groove 401 is symmetrically distributed on both sides of the top of the spray head body 3. The top of the spray head body 3 is located inside the water outlet 2. The built-in groove 402 is symmetrically distributed inside the walls 1 on both sides of the water outlet 2.
