Description

Technical Field

[0001] The utility model relates to the technical field of fire sprinkler heads, in particular to a fire sprinkler head which is easy to operate and adjust. Background Art

[0002] Fire sprinkler is a kind of sprinkler that is activated automatically under the action of heat within a predetermined temperature range, or activated by a control device according to a fire signal, and sprinkles water to extinguish fire according to the designed sprinkler shape and flow rate. It is part of the sprinkler system. In the fire extinguishing system, the fire sprinkler is one of the main devices and is generally installed in shopping malls, supermarkets, and hotels.

[0003] For example, the Chinese utility model provides a patent number of "a fire sprinkler that is easy to operate and adjust" CN202121477221.X, which includes a fire sprinkler body, a mounting head is provided at the upper end of the fire sprinkler body, a fixed base is provided at the top of the mounting head, a through groove is provided on the fixed base, and a card slot is provided on the surface of the through groove. By pressing the pressure rod, the spring is compressed, and the card block moves back to the inside of the cavity, and then the mounting head on the fire sprinkler body is plugged into the through groove of the fixed base, and the pressure rod is released. Due to the elastic deformation of the spring, the card block is connected to the card slot, thereby realizing the installation and fixation of the fire sprinkler;

[0004] Although the above document solves the problem that traditional fire sprinkler heads are prone to tilting when screwing, are not installed firmly, and during long-term use, rust may occur between the external threads of the fire sprinkler heads and the internal threads of the fixed base, which may cause the fire sprinkler heads to get stuck with the fixed base and make it inconvenient to disassemble and assemble the fire sprinkler heads, there is still the disadvantage that the spray angle cannot be adjusted, and the fire extinguishing effect of the fixed spray area is not good. For this reason, a fire sprinkler head that is easy to operate and adjust is introduced here. Utility Model Content
