Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
[0022] Please see Figures 1 to 4This utility model provides a technical solution: a fire sprinkler head installation structure, including a sprinkler head body 1 and a connector 2. The lower end of the connector 2 has two slots 3. Two connecting blocks 4 are fixed to the outer side of the sprinkler head body 1. A sealing ring 5 abuts against the upper end of the sprinkler head body 1, with the top surface of the sealing ring 5 abutting against the inner top of the connector 2. A rotating ring 6 is provided on the lower outer side of the connector 2. Two connecting block clearance grooves 17 are provided on the inner side of the rotating ring 6. Two protrusions 7 are fixed to the top surface of the rotating ring 6, and inclined surfaces 8 are provided on opposite sides of the two protrusions 7. Two limiting grooves 9 are provided on the outer circumference of the rotating ring 6, and slots 10 are provided on the inner side of each of the two limiting grooves 9. The inner sides of the two limiting grooves 9 are also slidably connected to... The limiting block 11 has a mounting groove 12 on its top surface and a retaining spring 13 embedded in the inner side of the mounting groove 12. The outer side of the rotating ring 6 is also provided with a toothed groove 14. The lower outer side of the connector 2 is also fixed with a support. A gear 15 is rotatably connected to one side of the support. A handle 16 is also fixed to the outer side of the gear 15. The outer sides of the two connecting blocks 4 are respectively inserted into the inner side of the two slots 3. The top surfaces of the two protrusions 7 are respectively abutted against the lower ends of the two connecting blocks 4. One side of each of the two limiting blocks 11 is fixedly connected to the outer side of the connector 2. The outer side of the retaining spring 13 is engaged with the inner side of the retaining groove 10. The outer side of the gear 15 is meshed with the inner side of the toothed groove 14. The connecting block 4 is located inside the connecting block clearance groove 17.
[0023] When installing the sprinkler head body 1, insert the connecting block 4 on the sprinkler head body 1 into the slot 3 on the connector 2 and place the sealing ring 5 between them. Then, turn the handle 16. The handle 16 drives the rotating ring 6 to rotate through the gear 15. During this process, the protrusion 7 on the rotating ring 6 contacts the connecting block 4 on the sprinkler head body 1, and the inclined surface 8 on the protrusion 7 slides against the lower end of the connecting block 4, thereby gradually pushing the connecting block 4 and the sprinkler head body 1 upward. This causes the sprinkler head body 1 to apply pressure to the sealing ring 5, thus sealing the sprinkler head body 1 and the connector 2. When the connecting block... 4. When the inclined surface 8 contacts the top surface of the protrusion 7, the contact surface is flat, which prevents slippage between the two. At the same time, the retaining spring 13 on the limiting block 11 is engaged and fixed with the retaining groove 10 on the rotating ring 6, which serves to fix the rotating ring 6. Through the above process, the sprinkler head body 1 can be installed quickly. At the same time, the connection stability is no less than that of the threaded connection method, thus solving the problem that the installation and disassembly process is more complicated due to the use of threaded and water pipe installation. According to national standards, fire sprinkler systems should be tested by water discharge once every quarter, which increases the inconvenience of maintenance.
[0024] The specific usage and function of this embodiment: When installing the sprinkler head body 1, the connecting block 4 on the sprinkler head body 1 is inserted into the slot 3 on the connector 2, and a sealing ring 5 is placed between them. Then, the handle 16 is rotated, and the handle 16 drives the rotating ring 6 to rotate through the gear 15. During this process, the protrusion 7 on the rotating ring 6 contacts the connecting block 4 on the sprinkler head body 1, and the inclined surface 8 on the protrusion 7 slides against the lower end of the connecting block 4, thereby gradually pushing the connecting block 4 and the sprinkler head body 1 to move upward, so that the sprinkler head body 1 applies pressure to the sealing ring 5, which plays the role of sealing the sprinkler head body 1 and the connector 2. When the connecting block 4 contacts the top surface of the protrusion 7 through the inclined surface 8, since the contact surface is flat, slippage between the two is prevented. At the same time, the retaining spring 13 on the limiting block 11 is engaged and fixed with the retaining groove 10 on the rotating ring 6, which plays the role of fixing the rotating ring 6. Through the above process, the sprinkler head body 1 can be installed quickly, and the connection stability is no less than that of the threaded connection method.
[0025] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
