The utility model is characterized in that an inner pipe sleeve is arranged in the water outlet pipe, the upper port point of the inner pipe sleeve is provided with a round ball, and the lower port point of the water outlet pipe is also provided with an outer pipe sleeve. The outer pipe sleeve is provided with a top rod at the inner part of the water outlet pipe, the upper end of the top rod is contacted with the round ball, water pressure is used by the round ball to close the water pipes. The utility model has the advantages of simple structure, practicality, high durability, fluent drainage, long service life, tight water pipe closing and no water leakage phenomena.

Description

A kind of improved water tap

The utility model belongs to the water tap field, particularly a kind of water supply pipe control tap.

Water supply pipe is very big with the application quantity of water tap, the used water tap of now general family all is the water tap of worm structure basically, utilize the water plugging piece extruding to live the purpose that water outlet realizes closing outlet pipe, the water tap of this structure is owing to be to utilize screw thread to close outlet pipe by force, the not tight phenomenon of water will appear closing in long-term use, and working life is short.Novel water tap has also appearred now, as notification number is the durable water tap of CN1143723, application number is 95109899, relate to a kind of water tap of forming by intake pipe, outlet pipe, valve body and wafer switch, between intake pipe and outlet pipe, form a valve chamber cavity, there is a valve body to block the upper end-hole of outlet conduit in the cavity, a wafer switch is arranged in the outlet conduit under the valve body, thereby the rotary wafer switch can be opened water pipe from the upper end-hole of outlet conduit with the valve body top, can effectively avoid leaking or closing the phenomenon that does not live water pipe.But structure is comparatively complicated, the phenomenon that simultaneously long-term use still can occur fitting badly.

The purpose of this utility model is to provide a kind of durable in use, water pipe to close tight improved water tap.

The utility model is achieved in that

A kind of improved water tap mainly is made up of intake pipe and outlet pipe, it is characterized in that: be provided with an interior pipe box in the outlet pipe, the upper end-hole place of pipe box is mounted with a sealing ball in this; Also be provided with an outer tube sleeve that can move up and down along lower end mouth outside the lower end mouth of outlet pipe, this outer tube sleeve is provided with a push rod in outlet pipe inside, and the upper end portion of this push rod contacts with above-mentioned ball.

After the utility model adopts above structure simple in structure, practical owing to utilize the pressure of water to use ball to close water pipe, have durable in use, draining is smooth, the effect of long service life, water pipe is closed tightly, water leakage phenomenon can not occur.

Accompanying drawing is a kind of structural representation of the present utility model;

Below in conjunction with accompanying drawing embodiment of the present utility model is elaborated.

In the accompanying drawing, 1 is that intake pipe, 2 is that outlet pipe, 3 is that ball, 4 is that interior pipe box, 5 is that outer tube sleeve, 6 is that push rod, 7 is a sleeve pipe.

As shown in drawings, the utility model is a kind of improved water tap, mainly is made up of intake pipe 1 and outlet pipe 2, is 90 ° of angles between intake pipe 1 and the outlet pipe 2, is provided with the installation screw thread in the port of intake pipe 1.Be provided with an interior pipe box 4 in the outlet pipe 2, pipe box 4 is to screw on the inwall of outlet pipe 2 from the mouth of pipe by worm structure in this; Should in the upper end-hole place of pipe box 4 be designed to V-structure, be mounted with a ball 3 in the port of this V-type, the diameter of this ball 3 is greater than the diameter of interior pipe box 4, make this ball 3 can seal the port of pipe box 4 in this and can not fall in the pipe box 4.Also be provided with an outer tube sleeve 5 that can move up and down along lower end mouth at the lower end mouth place of outlet pipe 2, this outer tube sleeve 5 is provided with a push rod 6 in outlet pipe 2 inside, and the upper end portion of this push rod 6 contacts with above-mentioned ball 3.

The upper end portion of pipe box 4 screws in the outlet pipe 2 in above-mentioned, and outlet pipe 2 is stretched out in the underpart.In being spun on by worm structure, above-mentioned outer tube sleeve 5 on the outer wall of pipe box 4 underparts, in this outer tube sleeve 5, also is fixed with a cross bar that is connected with push rod 6; In the pipe box 4, the upper end directly withstood on the ball 3 in push rod 6 stretched into.Also be provided with ball 3 limit stoper on 2 tube walls of the outlet pipe above the ball 3, this limit stoper is a pin that is packed on outlet pipe 2 inwalls.

For increasing practicability, in the outside of outlet pipe 2 sleeve pipe 7 is installed also, outlet pipe 2, interior pipe box 4 and outer tube sleeve 5 are enclosed in the sleeve pipe 7.

During use, rotate outer tube sleeve 5, outer tube sleeve 5 drives push rod 6 and moves up, and push rod 6 is jack-up ball 3 upwards, makes ball 3 and interior pipe box 4 upper end-hole places reserve the space, can realize discharging water.When closing, backward rotation outer tube sleeve 5, push rod 6 descends, ball 3 by self gravity and the pressure seal of water live in the upper end-hole of pipe box 4, realize closing the purpose of water pipe.Hydraulic pressure is big more, and sealing is tight more between ball 3 and the interior pipe box 4.
