The present invention relates to a multipurpose spanner for marine fire hose couplings.

In general, a ship fire hose coupling is a portable foam applicator that discharges a mixture of foam fire extinguishing agent and seawater, and a connection part of a fire hose, or a connection part connecting a fire hose to a fire hose and a hydrant valve. It is a connector that is fastened to both ends or one end of the fire hose for the purpose.

As shown in FIG. 1, the ship spanner coupling for ship extinguishing hose has a dedicated spanner having various shapes and sizes according to national standards.

1A illustrates a JIS coupling spanner 71 according to a Japanese industrial standard (JIS).

The JIS coupling spanner 71 is divided into 40 A, 50 A, and 65 A standards according to the size of the coupling.

1 (C) shows a spanner 72 for DIN and NS coupling according to a German standard (DIN: Deutsche Industrie-Normen) and a Norwegian standard (NS: Norsk Standard).

The DIN and NS coupling spanner 72 is also divided into 1-1 / 2 ", 2", 2-1 / 2 ", and 3" standards according to the size of the coupling.

1 (B) shows an ANSI coupling spanner 73 according to the American National Standards Institute (ANSI), which is also 1-1 according to the size of the coupling. / 2 ", 2", 2-1 / 2 ", 3" standard is used divided into.

In the meantime, as described above, the spanners for fire hose couplings of ships have used dedicated spanners of different structures and sizes according to the coupling shape and size of each country.

Specifically, a company that manufactures and supplies ship fire hoses and spanners has provided customers with dedicated spanners that meet the specifications of fire hose couplings in different countries.

However, due to various reasons such as ordering error and unrecognized design change, a spanner that does not fit the fire hose coupling installed in the ship is provided, or even the same coupling must be provided with a spanner that fits different sizes of coupling. Problems such as frequent confusion occurred in supply and management.

Therefore, even if the size or size of the fire hose coupling is different, it is necessary to supply a common spanner that can easily tighten or loosen the coupling with one spanner.

On the other hand, as a technology related to the spanner, the 'fire hose clamp spanner' (Korean Utility Model Publication No. 1992-0007168) that has been applied to tighten or loosen the coupling of various standards using a pulley has been applied.
