Buckling and pressing type hose connecting device

Abstract

The invention discloses a buckling and pressing type hose connecting device. The hose connecting device comprises a nut and a main body; the main body comprises a sleeve and an inner core; the inner core is an inner core rod penetrating through a conical through hole in the axial direction; the sleeve is a U-shaped sleeve; the sleeve and the inner core are integrally cast; annular insection is arranged on the inner wall of the sleeve; threads are arranged on the outer wall of one end of the inner core; an annular bevel gear is arranged on the outer wall of the other end of the inner core; thenut is connected to the end, provided with the threads, of the inner core; an O-shaped sealing element I is arranged between the nut and the inner core; an O-shaped sealing element II is arranged between the sleeve and the inner core; and the included angle between the conical surface of the conical through hole of the inner core and the axis of the inner core is 30 degrees. The hose connecting device is a connector which is integrally cast, in the casting process, some deviation of materials cannot be generated, the phenomena of uneven hardness and the like during heat treatment can be further avoided, the precision of the connector can be improved, deformation of the sleeve can be avoided, and the overall sealing performance can be improved.

Description

technical field [0001] The invention relates to the technical field of connecting fittings for pipe fittings, in particular to a crimping type hose connecting device. Background technique [0002] Ordinary joints generally include a core and a jacket. After the production is completed, the core and the jacket are two independent parts. After people buy this kind of joint, if they want to buckle and connect it with a rubber hose, they often need to perform the following operations. First Put the jacket on the rubber hose, then insert the core into the rubber hose, and finally use special equipment to buckle the jacket, relying on the deformation of the jacket to finally make the rubber hose and the joint crimped together. Although this kind of joint has been widely used, it is not difficult to see from the above operation process that the crimping connection with the rubber hose is more troublesome; because it is a split joint, the accuracy is low, which will cause inconsiste...

Problems solved by technology

[0004] Purpose of the invention: In view of the defects and insufficiencies of the prior art, solve the problem that the crimping operation of split joints and rubber hoses is relatively complicated and has low precision, which will cause inconsistent crimping force on the jacket, easy deformation, and thus reduce the sealing performance. After many practice improvements, the applicant designed a buckle-type hose connection device
