A kind of hose coupling structure

Technical field

The utility model relates to the accessory field of sanitaryware, and special and a kind of hose coupling structure that is applied to extraction-type tap is relevant.

Background technique

Extraction-type tap is connected with supply channel by flexible pipe, in use, by extraction head when leading fixed base is pulled out, the joint that connects extraction head and flexible pipe can be exposed, as shown in Figure 1, conventionally joint is to consist of spherojoint 1 ' and pipe box 2 ', one end of spherojoint 1 ' is fixed on flexible pipe 3 ' end by pipe box 2 ' riveted joint, needs due to packaging technology, on pipe box 2 ', have the vestige of riveting, therefore when extraction head is drawn out to use, the upper rough riveting vestige of joint pipe box 2 ' comes out, extremely inharmonious with leading overall appearance, affect attractive in appearance, and pipe box 2 ' has some setbacks when above riveting vestige also can cause extracting head reset, use uncomfortable.

Model utility content

For above-mentioned deficiency, the utility model provides a kind of hose coupling structure, by structural improvement, makes joint and flexible pipe riveting position without impression, reaches flat appearance, object attractive in appearance.

For reaching above-mentioned purpose, the technical solution of the utility model is: a kind of hose coupling structure, riveted joint is fixed on the end of flexible pipe, this joint by taking over, spherojoint, riveting sleeve and outer tube sleeve form, this is taken over as in hollow tube insertion flexible pipe, hollow portion forms the hole of water flowing, spherojoint protrudes outside flexible pipe and takes over combination, the middle part of spherojoint is provided with the hole of water flowing, front end moulding one bulb, riveting sleeve is enclosed within on the flexible pipe of adapter place flexible pipe and adapter is riveted together, and outer tube sleeve is nested with in the outside of riveting sleeve riveting sleeve is covered.

Described spherojoint protrudes outside flexible pipe one-body molded with adapter.

Described spherojoint protrudes and is threaded with adapter flexible pipe outside, and the end protrusion of this adapter is outside flexible pipe, and this end is provided with outside thread, and the aperture inwall of this spherojoint rear end is provided with and the internal thread of taking over outside thread and mating.

Described spherojoint protrudes and is threaded with adapter outside flexible pipe, the end of this adapter protrudes outside flexible pipe, this end is provided with outside thread, and the aperture inwall of this spherojoint rear end is provided with and the internal thread of taking over outside thread and mating, and the one-body molded rear end at spherojoint of outer tube sleeve.

The outer wall of described adapter is provided with anti-skidding convex tendon.

The spacing shoulder block of rear end moulding one of described spherojoint.

Adopt said structure, because the utility model is set up an outer tube sleeve in the outside of riveting sleeve, utilize butt joint outward appearance in outer tube sleeve to carry out seamless processing, while making joint be drawn out with extraction-type tap, can see smooth smooth appearance, make product appearance elegant in appearance, more competitive, and contribute to the smooth and easy reset of extraction-type tap to get back on leading fixed base.
