Description

Belt-pressing type water-converting belt joint Technical Field The utility model belongs to the technical field of fire-fighting connectors, and particularly relates to a belt-pressure type water-converting belt connector. Background In the fields of fire protection, hydraulic engineering, industrial water delivery and the like, the quick connection and reliable sealing of the water hose interface are key links for guaranteeing the efficient and safe operation. When traditional hosepipe interface is connected under the state of being under the area pressure, there is because of the hydraulic pressure impact leads to the interface to be difficult to aim at, sealed not tight even unable problem of connecting, very easily causes water waste and water pressure loss, seriously influences emergency rescue or engineering operation progress. In addition, traditional hosepipe interface goes out water control and relies on single manual operation mostly, and manual stagnant water reaction is slow under emergency, goes out water the opportunity and is difficult to accurate accuse, probably misses key operating time, and operation intensity is big, is unfavorable for long-time operation. With the continuous improvement of the requirements of the industry on the operation efficiency and the safety, a novel water hose interface capable of overcoming the defects is needed. Disclosure of utility model The utility model aims to provide a belt-pressure type water hose connector which is simple in structure, reasonable in design and convenient to use, and a linkage and pressure locking structure is additionally arranged in the fire hose connector, so that the belt-pressure connection of the water hose connector can be realized, emergency water stop can be realized by matching with a ball valve structure, the water hose connection time can be greatly shortened, fire water can be timely delivered to a fire scene, the fire extinguishing efficiency is effectively improved, and the disaster loss is reduced. The water valve hinge switch device comprises a female head and a male head, wherein the male head is matched and clamped with a clamp spring at the inner side of a front port of the female head through a clamping groove of a port, so that the female head and the male head are fixedly spliced, the female head consists of a middle cavity and a tail valve pipe, an L-shaped track sliding groove is formed in the upper end of the middle cavity, a water valve hinge switch piece I is movably clamped in a transverse track of the L-shaped track groove, a water valve hinge switch piece II is movably clamped in a longitudinal track of the L-shaped track groove, a rotating gear is respectively meshed with an upper rack at the front end of the water valve hinge switch piece I and an outer gear at the upper end of the water valve hinge switch piece II, linkage of the water valve hinge switch piece I and the water valve hinge switch piece II is achieved, a baffle embedding groove is formed in the lower end of the middle cavity, a vertically distributed water valve baffle is connected to the left side of the baffle embedding groove through a spring shaft, and the inner side of the water valve baffle is clamped with the water valve hinge switch piece II, so that limiting of the baffle is achieved. Preferably, the tail valve pipe is internally clamped with a ball valve, and the upper end and the lower end of the ball valve are connected with an external manual control handle. Preferably, the inside of the reserved groove in the middle of the first water valve hinge switch piece and the second water valve hinge switch piece is respectively connected with a slide rail wheel.
