The fire interface of the utility model has good sealing and stability. Although the product improves the sealing effect, the traditional fire interface method has many shortcomings in actual operation. The connection process is cumbersome and requires manual operation of multiple parts, which is time-consuming and prone to misoperation. In addition, the stability and sealing of the connection are poor, and it is easy to leak or fall off under the action of high-pressure water flow, affecting the fire extinguishing effect. Firefighters need to spend more time and energy to complete the connection in an emergency, delaying the rescue time, which may cause the fire to spread and greater property losses. Traditional methods reduce fire extinguishing efficiency and operational safety. Utility Model Content
