Abstract

The utility model relates to a dustproof inner plug with a flexible plastic water supply and drainage pipe, which can effectively solve the problems that an outer plug of a pipe occupies a large space, and falls off the mouth of the pipe easily, and the dust and dirt enter easily; the technical scheme for solving the problems is as follows: the inner plug comprises a dustproof pipe cap and an expansion supporting arm, wherein the expansion supporting arm consists of four independent leaves and is two rings of different circular ribs in size, and the expansion supporting arm is connected with the dustproof pipe cap through a plastic short section. The dustproof inner plug has good fastening performance, convenient disassembly and small occupied space, and is an innovation of plugs for pipes.

Description

A kind of plastics supplying drainage with stretchability prevents dust and uses interior plug

One, technical field

The utility model relates to the plastic tube plug, and particularly a kind of plastics supplying drainage with stretchability prevents dust and uses interior plug.

Two, background technique

The outer stifled mode of the many employings of current pipe stopper, plug is connected on the mouth of pipe of pipeline, the mouth of pipe is blocked, when many tubing are deposited in together with this, institute takes up space bigger, when the pipe end blocking binding is tight, come off from the mouth of pipe easily, when tubing exposes for a long time, easily advance dust and foul, easy cleaning not during installation influences the use of tubing, thus the improvement of tubing plug and innovate imperative.

Three, model utility content

At above-mentioned situation, for overcoming existing technological deficiency, the purpose of the utility model just provides that a kind of plastics supplying drainage with stretchability is dustproof uses interior plug, be used for internal diameter but the tubing of different wall, effectively solving the outer plug of tubing takes up space greatly, come off from the mouth of pipe easily, easily advance the problem of dust and booty, the technological scheme of its solution is: comprise dustproof pipe cap and expansion support arm, the expansion support arm is made up of four separate lobe leaves, with two circles circular muscle not of uniform size, the expansion support arm links together by plastics pipe nipple and dustproof pipe cap on it.The utility model tightness is good, convenient disassembly, takes up room for a short time, is tubing with the innovation on the plug.

Four, description of drawings

Fig. 1 is a plan view of the present utility model.

Fig. 2 is a side view of the present utility model.

Five, embodiment

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

Provide by Fig. 1 Fig. 2, the utility model includes dustproof pipe cap 1 and expansion support arm 2, expansion support arm 2 is made up of four separate lobe leaves, and with two circles circular muscle 3 not of uniform size, expansion support arm 2 links together by plastics pipe nipple 5 and dustproof pipe cap 1 on it.

In order to mount and dismount conveniently, said dustproof pipe cap 1 is circular, and there are two steps 4 in its top portion, push-and-pull position when mounting and dismounting for interior plug, lift by two steps that are provided with on the dustproof pipe cap, make finger that two direct force bearing points be arranged, simple and convenient during installation.

Said circular muscle 3 and expansion support arm 2 make it firmly shutoff tubing mouth when mounted according to the size adjustment of tube wall thickness, difficult drop-off, and tightness is good, uses widely, and it is little to take up space, and has significant social and economic benefit.
