Description

Flexible garden hose assembly

Technical field

This utility model relates to a kind of for the garden hose assembly for conveying water such as garden plant.

Background technology

Traditional garden hose is generally stored inside in spool, and with the risk that elimination is snarled when not using, therefore this volume is taken out the expense of adding and carries the complexity of water to garden plant.GB2490276 patent application document provides the instruction of the solution of the problems referred to above, flexible pipe therein includes a pair circular concentric pipe interconnected at respective end, one of them circular concentric pipe is elastic interior pipe, for delivering water into garden plant, another circular concentric pipe is flexible but inelastic outer tube, for limiting the amplitude of interior pipe expanded radially.Owing to interior pipe is elastic, therefore it can extend in the longitudinal direction, thus when interior pipe is in non-expansion state, interior pipe is likely to be significantly shorter than outer tube.Thus, when not carrying water to garden, compared with traditional flexible pipe corresponding to outer tube total length, the space that above-mentioned interior pipe takies is corresponding less, and so, outer tube is pulled to the length under interior pipe unswollen state by interior pipe.Thus, utilize above-mentioned configuration, when not in use, the less length of the size that himself is pulled under the non-expansion state corresponding to interior pipe by garden hoses naturally, and such as by current limiter (being such as connected to the hose free end hand-held water jet for irrigating plant) inwardly pipe conveying water time, only just it is rendered as the total length of outer tube.When flexible pipe is in unexpanded storage state, it is this that to be arranged in compactness aspect highly effective, but it is also more complicated structure simultaneously, additionally also has potential safety hazard, this is because: it is known that flexible but inelastic outer tube may rupture, flexible inner tube can expand at breaking part subsequently, until interior rostrum so bursts, explosively on the person of garden and/or use flexible pipe, discharge a large amount of water.

Utility model content

This utility model is solved the technical problem that to be in that to provide a kind of firmer and easily fabricated garden hose assembly, and this assembly remains the following advantages of garden hose: when not in use, and its length is substantially punctured into the unexpanded length of elastomeric element.

nullThe technical solution of the utility model is: a kind of flexible garden hose assembly，Including essentially no elastic waterproof delivery hose，Its two ends are respectively with first、Second adapter connects，Described first adapter is for by described hose connection to water source，Described second adapter is for by described hose connection to discharge current limiter，Such as garden water sprinkler or aerosol apparatus，Described first、Second adapter includes a pair boring respectively，One boring is for being transported to described second adapter by water from described first adapter，Another boring is for holding the two ends of elastic filament，Described elastic filament is connected to described first、The opposite side of the second adapter，Thus in use，Under the effect of the pressure produced when water enters described flexible pipe and leaves described flexible pipe and any relevant water restriction device via described second adapter via described first adapter，Described flexible pipe can expand into its greatest length，And，After stopping conveying water，Described flexible pipe is substantially punctured into the length of unexpanded described elastic filament in its longitudinal direction.

For convenience's sake, enter water drilling hole described in and water outlet boring is circular but it also may be non-circular, for instance oval or crescent.

The beneficial effects of the utility model are: by above-mentioned structure, described elastic filament is fixed between described first, second adapter by boring, described boring, with to flow through the water (flow) direction holed into water drilling hole and water outlet parallel to each other but do not contact, is come thus being mutually isolated.This makes the manufacture of water tube hose assembly become easy, described water tube hose assembly also includes into water boring and water outlet boring, the diameter of the two enough waters garden and send the use of water, wherein elastic filament itself is anchored between described first, second adapter, each end of elastic filament extends through the accommodation boring only holding filament, described hold boring with enter water drilling hole and water outlet and hole parallel, and be folded into quoit and be fixed between water drilling hole and water outlet boring, described quoit has no effect on the current in each adapter by the first boring.Therefore, by by flexible pipe be reduced to corresponding to the length under elastic filament unswollen state and flexible pipe be used for such as garden water sprinkler or aerosol apparatus water current limiter send water function separately, can easy, be manufactured inexpensively the adapter that each firm and durable, profile are brief, described adapter does not need a pair circular concentric flexible pipe---and one of them is elastic, for carrying water, and another is stiff, it is used for preventing elastic circular concentric flexible pipe from bursting.

Detailed description of the invention

First, with reference to Fig. 1, inflatable garden hose assembly 1 includes flexibility but is substantially non-elastic waterproof hose 2, described flexible pipe 2 one end has public connector 3, for being connected to water source etc., the other end has female connectors 4, for being connected to the water current limiter that form is garden water sprinkler or aerosol apparatus.After hose 1 connects and water flows into whole flexible pipe 2, flexible pipe 2 extends, until the outside of flexible pipe 2 is completely smooth, now the length of flexible pipe 2 can be 6 to 7 times of length shown in Fig. 1.When not in use, the position of flexible pipe 2 is as it is shown in figure 1, this is because the elastic filament 5 connecting public connector 3 and female connectors 4 is arranged in flexible pipe 2.

As Figure 2-3, one end of elastic filament 5 extends through the filament of public connector 3 and holds boring 6, and public connector 3 includes water outlet boring 7.By crimped at diameter more than in the quoit 8 of boring 6, it is possible to prevent the end of filament 5 from departing from from boring 6.

The other end of filament 5 is fixed on female connectors 4 by another packing ring being arranged in above filament accommodation boring 6, and the other end of described filament 5 holds boring 6 extension along described filament, and the accommodation boring 6 of described filament is parallel with entering water drilling hole.

Should be appreciated that the manufacture of public connector 3 and female connectors 4 is relatively easy, because corresponding to, each diameter of the diameter of the unswollen state of filament 5 only needing a boring, just can adapter fix in position by quoit 8；Similarly, in order to introduce the water in flexible pipe 2 and allow water escape freely out flexible pipe 2, it is possible to be readily formed water inlet boring and the water outlet boring of the major axis being parallel to filament accommodation boring in public connector 3 and female connectors 4.Therefore, compared with the hose in GB2490276 patent application document, the hose structure of the present invention is simpler, although smooth not, but under non-working condition, remains able to be stored automatically in structure closely.
