Abstract

The utility model discloses a water pipe joint which is composed of an inner joint and a conical thread sleeve which are mutually connected through threads. An interpenetrated water hole is arranged at the middle part of the inner joint, a thread hole is arranged at the upper end of the inner joint, a threaded section part is arranged in the middle of the inner joint, a conical bushing which is connected with a water pipe is arranged at the lower end of the inner joint. A circular bushing with inner threads is arranged at the upper end of the conical thread sleeve, and a gap which accommodates the thickness of the water pipe wall is left between a conical part of the conical thread sleeve and the conical bushing of the inner joint. The water pipe joint has simple connection method; when being installed, the conical bushing of the inner joint is inserted into a plastic water pipe easily, and the conical thread sleeve arranged at the outer ring of the joint is only needed to be screwed to be fixedly locked by hand; after connection, the water pipe joint does not have water leakage and ventilation.

Description

Water pipe adapter

Technical field

The utility model relates to and is used for joint that plastics hose and water tap or water pipe are linked together.

Background technique

Existing water pipe adapter is of a great variety, as Chinese patent CN200520049933.6 disclosed " a kind of water pipe adapter ", Chinese patent CN200620028311.X disclosed " a kind of water pipe adapter " and for example, though these joints have certain using effect, but structure is comparatively complicated, leakage phenomenon takes place in operation inconvenience easily.

The model utility content

At the deficiency that prior art exists, the utility model aims to provide the water pipe adapter of a kind of simple in structure, easy operating and stable performance.

The technical solution adopted in the utility model is:

A kind of water pipe adapter, this joint is by forming by interconnective spigot of screw thread and taper swivel nut, the middle part of described spigot is provided with the water hole of perforation, the upper end is a screw mouth, the centre is the thread section part, the lower end is for connecting the taper of water pipe, and the upper end of taper swivel nut is the circular casing that has internal thread, leaves the gap that holds the water pipe wall thickness between the tapering part of lower end and the taper of spigot.

Be provided with the barrel portion of one section inside indentation of diameter between the thread section part of described spigot and the taper.

Have the multiple tracks annular ridge on the taper of described spigot.

Described fin surface is also tapered.

The utility model marching method is simple, earlier the taper of spigot is easily inserted plastic water pipe during installation after, only with hand screws the taper swivel nut of joint outer ring, can not seep water after the connection securely with its locking, airtight.

Embodiment

Below in conjunction with accompanying drawing the utility model is described in further detail.

Description of reference numerals is as follows:

11---spigot 12---taper swivel nut

13---water hole 14---screw mouth

15---thread section part 16---taper

17---barrel portion 18---annular ridge

19---plastic water pipe

Shown in Fig. 1～4, this water pipe adapter is by forming by interconnective spigot 11 of screw thread and taper swivel nut 12, the middle part of spigot 11 is provided with the water hole 13 of perforation, the upper end is for connecting the screw mouth 14 of water tap or water pipe, the centre is a thread section part 15, the lower end is for connecting the taper 16 of water pipe, be provided with the barrel portion 17 of one section inside indentation of diameter between thread section part 15 and the taper 16, have multiple tracks annular ridge 18 on the taper 16, the surface of fin 18 is also tapered, the upper end of taper swivel nut 12 is the circular casing that has internal thread, leaves the gap that holds the water pipe wall thickness between the tapering part of lower end and the taper of spigot 16.

Shown in Fig. 5,6, during installation, earlier plastic water pipe 19 is passed from taper swivel nut 12, taper 16 with spigot inserts plastic water pipe 19 then, with the tight taper swivel nut 12 of hand-screw, by taper swivel nut 12 plastic water pipe 19 is pressed on the taper 16, the position of taper swivel nut 12 is more by last again, and the gap between the taper 16 is more little, and it is firm more that plastic water pipe 19 is locked.

The utility model is not limited to above-mentioned preferred forms, and anyone can draw other various forms of products under enlightenment of the present invention.Though but on its shape or structure, do any variation, every identical with the utility model or akin technological scheme is all within its protection domain.
