Background technology
Metal arc plasma cutters is widely used in fire-fighting and special duty team rescue occasion, is one of requisite instrument in modern fire-fighting and rescue, orcible entry work, is also one of strong " weapon " in special duty team rescue work.Because metal arc etc. is from obtaining high temperature (over Fahrenheit 10 after the metal arc plasma combustion rod burning of cutter, 000 degree), make the cutting speed of metal arc plasma cutters express, can allow fireman within the extremely short time, break rapidly the facilities such as window, door, lock and guard rail, save or fire-fighting work.The burning " strength " of metal arc plasma combustion rod makes the cutting speed of metal arc plasma cutters considerably beyond any fluid pressure type break-in tool, and the operation sound of metal arc plasma cutters is little, can coordinate the special requirement of special duty team when carrying out special duty.
When metal arc plasma combustion rod is used for cutting operation, by a hand-held gun head, fix and be connected with firing circuit with gas piping, particularity due to metal burning rod operating condition, on existing market, be not exclusively used in the connector of connection metal rod and hand-held gun head, affected efficiency and the security of operation.
Utility model content
The weak point that the utility model exists for fear of prior art, provides a kind of connector that is exclusively used in connection metal rod and hand-held gun head, and this connector is simple in structure, fixed, easy to use, safe.
The utility model technical solution problem adopts following technical scheme:
Rifle head connector for metal burning rod, its design feature is, described connector consists of the first connector expansion head and the second connector;
Described first connector one end is internal thread connecting portion one, and for connecting hand-held gun head, the other end is external screw thread connecting portion, and the end of described external screw thread connecting portion is provided with cavity volume;
Described expansion head comprises base portion and is connected to the expanded joint portion being comprised of a plurality of elastic expansion sheets on base portion, and the cavity volume matched in clearance of described base portion and the first connector is provided with expanded joint seam between described elastic expansion sheet;
Described second connector one end is provided with internal thread connecting portion two, and the other end is provided with the inner chamber with expansion head expanded joint portion expanded joint;
Between described the first connector, expansion head and the second connector, be provided with the air flue of perforation.
The utility model design feature is also:
Described elastic expansion sheet consists of cylinder cardinal extremity and round platform front end; Described cylinder cardinal extremity consists of the staged cylinder increasing to top body diameter ladder from bottom.
The outer wall of described the first connector is provided with pair of parallel face.
The interior cavity outer wall of described the second connector is provided with notched rotating disc.
Described the first connector and the second connector adopt the aluminum alloy material of lightweight, and described expansion head adopts copper alloy material.
Compared with the prior art, the utility model beneficial effect is embodied in:
The utility model is the connector that is exclusively used in connection metal rod and hand-held gun head, and this connector is simple in structure, fixed, easy to use, safe.
