[0026] Nozzle base 1 is provided with multiple connecting ports, so setting, makes integrated piercing fire sprinkler connect with adjacent integrated piercing fire sprinkler by pipeline, forms series system, and user can expand according to use demand.When integrated piercing fire sprinkler needs independent use, keep one connecting port to connect fire extinguishing system pipeline by quick connector, and the rest connecting port can be closed using plug, improve the flexibility of use.

[0027] It needs to be explained that the number of connecting port can be designed as two or more according to use demand, to meet different fire extinguishing demand.And the position of connecting port can be set on any side wall of nozzle base 1 according to use demand.

[0028] The quick connector can rotate 360 degrees relative to the connecting port to connect the pipeline of the fire extinguishing system in multiple directions, thereby providing more options for connecting the pipeline.

[0029] By integrating the piercing assembly in the nozzle base 1, the overall structure is compact, the integration degree is high, the design is reasonable, the overall stability and sealing are improved, and the problems such as leakage are effectively avoided. The nozzle base 1 adopts a flat structure, and the moving direction of the top rod 4 is parallel to the first side wall 11, so that the overall height and thickness are compressed, which is beneficial to reduce the space occupation of the integrated piercing fire nozzle, and makes the installation and maintenance operation more convenient, facilitates the laying of pipelines and lines, has good flexibility, and is especially suitable for narrow or complex environments such as energy storage cabinets, and provides good fire extinguishing effect.
