The easy-to-connect type water tap

Technical field

The utility model relates to water tap, especially the water tap of water outlet band water pipe adapter.

Background technique

One end of existing water tap is connected with intake pipe, the other end is a water outlet, socket flexible pipe on water outlet can cause current the place that needs, as water receiving, bath or the like, flexible pipe in the past all is to be socketed on the water outlet of water tap by self the power of tightening, firm inadequately, come off easily, if use the iron wire banding, not easy to operate again and dismounting, the structure of other link is too complicated again.

The model utility content

At the deficiency that prior art exists, the utility model aims to provide a kind of easy-to-connect type water tap.Have water pipe adapter on the water outlet of this water tap, can realize quick connection, and simple in structure, easy operating, be connected firmly.

The technical solution adopted in the utility model is:

A kind of easy-to-connect type water tap, its water outlet is provided with split type spigot and swivel nut, described spigot middle part is the water hole that connects, the upper end is connected with the water outlet internal thread by outside thread, the lower end is for inserting the taper of water pipe, swivel nut is connected with the outside thread of water outlet by internal thread, its screw thread down inwall and the taper of spigot between form the annular space of tightening water pipe.

Between the thread section part of described spigot and the taper is one section barrel portion.

Described cylinder part is arranged with concavo-convex lines.

The taper of described spigot has a joint or a more piece conical surface.

Have one or multi-channel annular ridge on the taper of described spigot.

Described fin surface is also tapered.

The lower end diameter of described swivel nut is offered internal thread greater than the upper end and by conical surface transition on the inwall of upper end, and the lower end has smooth inwall.

The utility model connecting means is simple, earlier cylindrical swivel nut is threaded to the thread section part of water outlet, again plastic water pipe is easily inserted on the taper of spigot, only with hand oppositely screws cylindrical swivel nut then, can be securely with its locking, do not seep water after the connection, airtight, be applicable to various water taps such as ceramic valve core, ball valve core, cock spool.

Embodiment

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

Description of reference numerals is as follows:

1---water outlet 2---spigot

3---cylindrical swivel nut 4,4 '---outside thread

5---taper 6---cylindrical body

The concavo-convex lines of 7---water pipes 8---

As Fig. 1, shown in 2, the water outlet 1 of this water tap is provided with split type spigot 2 and cylindrical swivel nut 3, the middle part of spigot 2 is the water holes that connect, the upper end is connected with the water outlet internal thread by outside thread 4, the lower end is for inserting the taper 5 of water pipe, it between outside thread 4 and the taper 5 one section cylindrical body 6, have concavo-convex lines 8 on it, taper 5 has a joint or a more piece conical surface, as shown in Figure 4, the lower end diameter of swivel nut 3 is greater than the upper end and pass through conical surface transition, offer internal thread on the inwall of upper end, the lower end has the outside thread 4 of the cylindrical swivel nut 3 of smooth inwall by internal thread and water outlet 1 ' be connected, its screw thread down smooth inner wall and the taper 5 of spigot between form the annular space of tightening water pipe 7.

As shown in Figure 3, when being connected with water pipe, earlier cylindrical swivel nut 3 is threaded to the thread section part of water outlet 1, after again plastic water pipe 7 easily being inserted the taper 5 of spigot, only with hand oppositely screws cylindrical swivel nut 3, can plastic water pipe 7 be tightened on taper 5 by cylindrical swivel nut 3, and the position of cylindrical swivel nut 3 is more by following, and the gap between the taper 5 is more little, and it is firm more that plastic water pipe 7 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.For example have the multiple tracks annular ridge on the taper of spigot, the fin surface is also tapered, and perhaps water tap adopts various spools such as ceramic valve core, ball valve core, cock spool.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.
