Abstract

The utility model discloses a water pipe joint which is composed of an inner joint and a cylindrical 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 section of smooth inner wall is left in the region below inner threads of the cylindrical thread sleeve, and a gap which accommodates the thickness of the water pipe wall is left between the section of smooth inner wall and the conical bushing of the inner joint. The water pipe joint has simple connection method, the cylindrical thread sleeve is first screwed to the threaded section part of the inner joint, and then, after the conical bushing of the inner joint is easily inserted into a plastic water pipe, the cylindrical thread sleeve arranged at the outer ring of the joint is only needed to be screwed in a reverse way to be fixedly locked. 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 " kind 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 cylindrical 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 cylindrical swivel nut screw thread zone down within it leaves one section smooth inwall, and forms the gap that holds the water pipe wall thickness between the taper of spigot.
Be provided with one section cylindrical body between the thread section part of described spigot and the taper.
Be provided with one section cylindrical body between the thread section part of described spigot and the screw mouth.
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 cylindrical swivel nut is threaded to the thread section part of spigot during installation, after again the taper of spigot easily being inserted plastic water pipe, only with hand oppositely screws the cylindrical 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:
The cylindrical swivel nut of 11---spigots 12---
13---water hole 14---screw mouth
15---thread section part 16---taper
17---cylindrical body 18---annular ridge
19---inwall 20---plastic water pipe
Shown in Fig. 1~4, this water pipe adapter is by forming by interconnective spigot 11 of screw thread and cylindrical 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 one section cylindrical body 17 between thread section part 15 and the taper 16, also be provided with one section cylindrical body 17 between thread section part 15 and the screw mouth 14, have multiple tracks annular ridge 18 on the taper 16, the fin surface is also tapered, cylindrical swivel nut 12 screw thread zone down within it leaves one section smooth inwall 19, and forms the gap that holds the water pipe wall thickness between the taper of spigot.
Shown in Fig. 5,6, during installation, earlier cylindrical swivel nut 12 is threaded to the thread section part of spigot, again behind the taper 16 light insertion plastic water pipes 20 with spigot, only with hand oppositely screws the cylindrical swivel nut 12 of joint outer ring, can plastic water pipe 20 be pressed on the taper 16 by cylindrical swivel nut 12, and the position of cylindrical swivel nut 12 is more by following, and the gap between the taper 16 is more little, and it is firm more that plastic water pipe 20 is locked.
Second kind of spigot as shown in Figure 7, the taper 16 of this spigot 11 is the two-segment type structure, combine by two cones, its diameter terminad dwindles gradually, and what so not only can be connected with water pipe is more firm, but also helps shortening the length of taper, thereby saving Manufacturing material, reduce cost, all the other structures and first kind of spigot are basic identical, just repeat no more here.
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.
