DETAILED DESCRIPTION
[0018] The male head 5 is arranged at one end of the fire hose body 1, one side of the inside of the female head 6 can be inserted into the male head 5, the other side of the inside of the female head 6 is provided with a valve nut 4 for connection with the fire valve, the male head and the female head are connected with an interface connection 3, the interface connection 3 is provided with a groove 34, the groove 34 is provided with a steel ball 32 for limiting the sliding of the male head 5, the gap between the female head 6 and the male head 5 is provided with a steel ball 32 for limiting the sliding of the male head 5, after the male head 5 is inserted into the female head 6, the steel ball 32 is limited by the limiting sleeve 2 and the male head 5 at the groove 34, realizing the self-locking function after the fire hose is connected to the valve; the limiting sleeve 2 is nested in the upper end of the female head 6, the gap between the limiting sleeve 2 and the female head 6 and the right side of the steel ball 32 are provided with a connecting spring 33, the sleeve can slide to compress the spring, so that the male head 5 can be inserted inward and the steel ball 32 can slide into the groove of the male head 5; the gap between the limiting sleeve and the female head 6 and the left side of the steel ball 32 are provided with a sleeve limiting ring 31 for limiting the sliding of the limiting sleeve 2, preventing the limiting sleeve 2 from sliding outward too much to cause the steel ball 32 to pop out. The inside of the female head 6 is provided with a female head connecting piece 8 for fixed connection, the inside of the male head 5 is provided with a male head connecting piece 7 for fixed connection.
[0019] Working principle: when the fire hose is connected to the fire valve, the male head connecting piece is connected to the female head connecting piece through magnetic material adsorption, and the female head connecting piece is pushed and fixed to the female head fixing block through the female head spring, at this time the male head fixing piece also pushes the male head connecting piece to the male head spring in a tight state; at this time, under the pressure of the male head shell, the steel ball will retract into the groove, and the sliding sleeve will make the connecting spring relax until the sleeve is limited by the sleeve limiting ring, at this time the steel ball is limited by the limiting sleeve and the male head in the groove, realizing the self-locking function after the fire hose is connected to the valve, and the connection is stable and not easy to loosen.
[0020] At this time, the pressure-resistant material of the shell of the male head connecting piece and the female head connecting piece can prevent the high-pressure water flow from the fire valve from damaging the connecting piece and causing the interface to be unstable.
[0021] When the fire hose needs to be disconnected from the valve, the limiting sleeve is pushed to compress the connecting spring, at this time the gap between the sleeve and the female head will make the steel ball no longer be limited; at this time the fire hose is pulled out, the steel ball will reset to the gap between the female head, at this time the male head connecting piece and the female head connecting piece are loose, without the use of tools, the disconnection of the fire hose interface can be conveniently realized.
[0022] Furthermore, it should be understood that although the specification is described in terms of embodiments, not every embodiment includes every feature or implementation described herein. The specification can include implicit combinations of explicitly mentioned features and / or implicit combinations of implicitly mentioned features. Such combinations are also expressly included within the scope of the specification and an embodiment.
