Abstract

The invention discloses a fast inserting type disengaging-preventing and binding-free hose coupling which comprises a male opening, a female opening, two matched ports, a movable clamping ring, spring gaskets and a locking block. The matched ports are connected with the male opening and the female opening respectively. The male opening and the female opening are provided with outer threads matched with the matched ports. The matched ports are internally provided with inner threads matched with the male opening and the female opening. Corresponding grooves are formed in the male opening, the female opening and the two matched ports. The spring gaskets are installed on the grooves. The movable clamping ring is installed on the male opening. The locking block is installed in the female opening. The connection between the disengaging-preventing and binding-free hose coupling with a hose must meet the requirements for disengaging preventing and pickling preventing; the hose coupling is easy to demount; and the phenomenon that the part, at the hose coupling, of the hose is damaged, and consequently use of the whole hose is affected is avoided. If the part, at the coupling, of the hose is damaged, the coupling can be demounted rapidly, the damaged part of the hose is cut off, the coupling can recover to be used after being installed, and the whole process of replacing the hose is short in time and convenient to conduct.

Description

Push-in anticreep exempts to prick hose coupling

Technical field

The present invention relates to a kind of push-in anticreep to exempt to prick hose coupling.

Background technique

In prior art, with the develop rapidly of society, the fire rescue task that fire-fighting party faces is also day by day complicated; Fire-extinguisher water hose is the requirement in fire attack, especially putting out a fire to save life and property in large-sized fire process, the usage quantity of water-band is more, when carrying out fire rescue, need lay polydisc water-band, at this moment the connection of water-band is particularly important, joint should make hydraulic pressure be guaranteed, also need the connection of interface fastening and quick detachable, in this context, design a fast anticreep of inserting and exempt to prick hose coupling.

Summary of the invention

The object of this invention is to provide one and can either ensure hydraulic pressure, the connection of interface also can be made fastening and easily detachable quick anticreep exempt from prick hose coupling.

The technological scheme that the present invention is adopted for achieving the above object is: a kind of push-in anticreep exempts to prick hose coupling, comprise public mouth, female mouth, two mating interfaces, movable snap ring, compression spring and locking block, mating interface is connected with male mouth and female mouth respectively, described male mouth and female mouth are provided with the outside thread matched with mating interface, be provided with in described mating interface and public mouth, the internal thread that female mouth matches, described public mouth, female mouth and two mating interfaces are provided with mutually corresponding groove, compression spring install mating interface on groove, movable snap ring is arranged on public mouth.

Connection between described male mouth and female mouth adopts push-in structure.

Described movable snap ring inside has the second groove.

Described public mouth is provided with the protruding block corresponding with the second groove of movable snap ring inside, and protruding block inside is provided with spring and clamping block.

Described public mouth and mating interface adopt two kinds of Placements, and one is threaded, and utilize thread pitch to compress water-band; Another kind utilizes socket head screw to hold out against built-in compression spring, compressed the Placement of water-band by compression spring.

A kind of push-in anticreep of the present invention exempts to prick hose coupling, and the anticreep is connected with water-band, to exempt from bundle effective; The cooperation between the projection of movable snap ring and public mouth is utilized to meet anticreep; Utilize the twice between mating interface and hose coupling to connect operation to ensure to exempt to prick; And connection between water-band and interface is quick detachable, the use of the whole water-band of impact after avoiding hose coupling place water-band to damage; Jointing water-band is damaged, by interface rapid removal, breakage spot water-band can be dismissed, and can recover to use after installation, and the whole process time changing water-band is short and convenient.
