Description

Technical Field

[0001] The utility model relates to the field of fire-fighting equipment, in particular to a multifunctional quick connection and sealing device for a fire hydrant. Background Art

[0002] The working principle of a fire hydrant hose connector mainly involves two aspects: connection and sealing;

[0003] In terms of connection, a fire hydrant hose connector usually adopts methods such as threaded connection, clamp connection or quick connector connection, etc. Threaded connection is achieved by rotating the connector to match its threads with those of the fire hydrant and the hose. Clamp connection is to fasten the hose to the fire hydrant through a clamp. Quick connector connection is to achieve quick connection and disassembly through specific mechanisms such as buckles and pins.

[0004] In terms of sealing, a sealing gasket or sealing structure is usually provided inside the connector to ensure the sealing performance of the connection and prevent water leakage. The sealing gasket can effectively fill the gap between the connector and the fire hydrant and the hose to prevent water flow from leaking.

[0005] Taking the threaded connection method of a fire hydrant hose connector as an example, in an emergency, it is necessary to hold the joint of the two water pipes and fix them by rotating and screwing, which directly increases the installation time of the fire hose. The threaded connection method has poor sealing performance and is prone to water leakage at the connection. Content of the Utility Model

At the same time, a communication cylinder is fixedly arranged on the left surface of the installation table, and a receiving surface is arranged on the right surface of the installation table. A receiving groove and a locking groove are opened on the surface of the receiving surface. The connecting seat includes a docking table, and the end of the docking table is fixedly connected to an outer sealing frame. At the same time, a docking surface is arranged inside the outer sealing frame, and a locking block is fixedly installed on the surface of the docking surface. A sealing ring strip is fixedly arranged outside the docking surface.

[0008] Preferably, a sealing gasket is fixedly arranged on the outer surface of the installation table, and the sealing gasket is annular. At the same time, the sealing gasket covers the outer surface of the installation table and is sealed through the sealing gasket.
