Abstract

The utility model relates to a quick coupling for hoses, which is presented for providing a coupling for hoses and has the advantages of simple structure, easy operation and good performance. The coupling for hoses is composed of a coupling body and a screw nut. The left end of the coupling body is provided with an inserting column with a central through hole. A blind cavity and a ring wall are formed on the periphery of the inserting column. The outer surface of the end part of the ring wall is composed of a conical surface and forms a jaw clamp with a dentate inner clamping surface and a strip-shaped groove. The periphery of the ring wall is provided with outer threads. The screw nut is provided with a central through hole with an expanding hole with threads. The central through hole can allow the small end of the conical surface of the ring wall of the coupling body to pass through. The right end of the coupling body is composed of a universal coupling seat which is interpenetrated with the central through hole on the left end of the coupling body.

Description

Flexible pipe rapid pipe joint

The utility model belongs to the quick-acting type pipe joint that is used for flexible pipe, particularly a kind of flexible pipe rapid pipe joint.

When connecting flexible pipe, normally a end that earlier will special joint is sleeved on the flexible pipe, adopts the method for lock ring that special fit is fixedly mounted on the flexible pipe again, with the other end of special fit flexible pipe is connected with other parts more at last.This hose coupling, not only make, cumbersome in the use, and very easily leak in the joint of flexible pipe and special fit.

The purpose of this utility model provides a kind of simple in structure, easy to use, flexible pipe rapid pipe joint that usability is good.

The utility model is made up of fittings body and nut, the left end of fittings body is the hose coupling seat, which is provided with the inserting pin of band central through bore, at blind circlewise chamber of inserting pin peripheral shape and ring wall, the outer surface of ring wall end is conical surface, and constitute evenly spaced clamp jaw and strip slot, and the internal surface of clamp jaw end is the dentation clamp face, the periphery of ring wall is provided with outside thread; Nut is provided with the central through bore of threaded reaming, and the screw thread reaming is meshed with outside thread on the fittings body ring wall, and central through bore can allow the microcephaly of fittings body ring wall conical surface end to pass through on it; The universal joint seat that the right-hand member of fittings body connects for the left end central through bore.

Because the utility model is made up of fittings body and nut, the left end of fittings body is the hose coupling seat, which is provided with the inserting pin of band central through bore, at blind circlewise chamber of inserting pin peripheral shape and ring wall, the outer surface of ring wall end is conical surface, and constitute evenly spaced clamp jaw and strip slot, and the internal surface of clamp jaw end is the dentation clamp face, the periphery of ring wall is provided with outside thread; Nut is provided with the central through bore of threaded reaming, and the screw thread reaming is meshed with outside thread on the fittings body ring wall, and central through bore can allow the microcephaly of fittings body ring wall conical surface end to pass through on it; The right-hand member of fittings body is the universal joint seat that connects with the left end central through bore; During use, flexible pipe is inserted on the inserting pin of fittings body left end, and the blind chamber of the ring-type that is positioned at fittings body, fastening nut, the microcephaly of central through bore along the conical surface of fittings body ring wall conical surface end from fittings body ring wall conical surface end on the nut moved to major part, so that clamp jaw tightens, thereby make flexible pipe under the dentation clamp face chucking power effect of clamp jaw, closely be fixed on the inserting pin; The universal joint seat of right-hand member is connected with general pipe, not only simple in structure, easy to use, and can not leak, usability is good, thereby reaches the purpose of this utility model.
