Abstract

The utility model discloses an extensible hose with a valve. The extensible hose with the valve comprise a hose body (10). The hose body (10) comprises an outer tube (12) and an inner tube (14) contained in the outer tube (12). The outer tube (12) and the inner tube (14) are respectively provided with a first end and a second end, wherein the first end of the outer tube (12) and the first end of the inner tube (14) are connected with each other through a first coupling piece (18), and the second end of the outer tube (12) and the second end of the inner tube (14) are connected with each other through a second coupling piece (16). The valve (17) is arranged on the second coupling piece (16) arranged at the second ends. The valve (17) enables an inner cavity of the inner tube (14) to be communicated with or separated from the outside. When the extensible hose with the valve is used, an extra fluid flowing-stopping controller is not needed, and the extensible hose can control flowing and stopping of fluid (or liquid).

Description

The valvular Telescopic flexible pipe of tool

Technical field

The utility model relates to flexible pipe field, and especially, the utility model relates to the valvular Telescopic flexible pipe of tool.

Background technique

For delivering the flexible pipe of various fluids, be known in the art.Conventional garden hose is made by rubber or other resilient flexibility material of the thing such as the photochemical derivatization such as synthetic rubber, thermoplastic elastomer conventionally.The prominent question that conventional garden hose meets with relates to the storage of flexible pipe when not in use.Garden hose can be stored on hose reel, is positioned in reservoir vessel, or only stays on the ground.Although storage device is practical in some cases, Consumer can not use or not expect to adopt reservoir vessel in many cases.For example, Consumer may live in apartment or small-sized set apartment, and wishes to benefit from the garden hose for irrigating plant, automobile washing etc., but does not have the room for garden hose storage device.Flexible pipe may be stayed in the vehicle body of vehicle or volume is put in the corner of balcony, to make great efforts to take as far as possible little space.Another embodiment is the owner of ship, RV or aircraft, and they may wish flexible pipe to stay in vehicle.These places cannot be implemented for flexible pipe reservoir vessel.

There are many situations that flexible pipe is useful that store in as far as possible little space.If Consumer does not have for storing the device of flexible pipe, they must be positioned over flexible pipe on ground in the mode that does not make flexible pipe twine within Yu Shen as possible systematically.If it is improper to place, when flexible pipe is untied or launch, will be tending towards kinking.The common house-owner of frequent use flexible pipe meets with this problem conventionally, and wherein the inappropriate storage of flexible pipe can cause the generation kinking.Flexible pipe can be made for and there is thick sidewall and prevent from kinking and tolerating pressurization.Can also use fiber reinforcer, such as ribbon or after adding external coating, weave, all these have all increased the weight of flexible pipe.For this reason, provide lightweight, length is collapsible and the resistance to flexible pipe kinking is extremely useful.

This Telescopic flexible pipe using in prior art self can not be controlled the break-make of fluid conventionally.

Therefore, related domain is needed is such Telescopic flexible pipe: when it uses, do not need extra fluid on-off controller, himself can control the break-make of fluid (or liquid).

Model utility content

Technical problem to be solved in the utility model is to provide the valvular Telescopic flexible pipe of a kind of tool, and this Telescopic flexible pipe in use, does not need extra fluid on-off controller, and himself can control the break-make of fluid (or liquid).

The utility model solves the problems of the technologies described above adopted technological scheme: the valvular Telescopic flexible pipe of tool, comprises hose main body; The inner tube that described hose main body comprises outer tube and is contained in described outer tube inside; Described outer tube and described inner tube have first end together with being attached to by the first male part the second end together with being attached to by the second male part separately; And, on described second male part of described the second end, being provided with valve, described valve makes the internal cavity of described inner tube connect or isolation with extraneous.

Second male part at described the second end place comprises outside thread, stage casing, the sleeve setting gradually; On described stage casing, go back connecting tubular extension part; Described tubulose extension part has hollow inside, and extends to the inside of inner tube, outer tube and sleeve; Described inner tube, outer tube are fastened on tubulose extension part together with sleeve; Described valve is arranged on described stage casing.Wherein, described outside thread, stage casing and tubulose extension part can adopt metal-integral to form.

First male part at described first end place comprises arranging accepts described externally threaded internal thread part.

Described outer tube is formed by non-resilient sill, and described inner tube consists of resilient base material.Described non-resilient sill is the material that selects the group of free nylon, polyester or polypropylene composition.Described non-resilient sill through braiding, woollen yarn knitting or circumvolution so that there is roughly stiff length and girth.

Described resilient base material can be natural latex rubber, can also use other composite with the elastic characteristic that is similar to rubber.

In sum, compared with prior art, tool has the following advantages the utility model:

(1), the internal cavity that uses self end of the utility model Telescopic flexible pipe to arrange to make inner tube connects or the valve of isolation with extraneous, thereby make himself can control fluid break-make, facilitated the use of flexible pipe.

(2), the utility model structure reasonable in design, easy to use.

Embodiment

The following examples can make those skilled in the art's comprehend the utility model, but limit never in any form the utility model.

Embodiment one

As shown in Fig. 1,2 and 4, the valvular Telescopic flexible pipe of tool, comprises hose main body 10; The inner tube 14 that described hose main body 10 comprises outer tube 12 and is contained in described outer tube 12 inside.The first end of described outer tube 12 and described inner tube 14 forms together with being attached to by the first male part 18; Its second end is attached to together and is formed by the second male part 16.

On described second male part 16 of described the second end, be provided with valve 17, described valve 17 makes the internal cavity of described inner tube 14 connect or isolation with extraneous.

Fig. 2 and 3 shows the concrete setting of described valve 17.As shown in the figure, second male part 16 at described the second end place comprises outside thread 20, stage casing 22, the sleeve 26 setting gradually; On described stage casing 22, go back connecting tubular extension part 32; Described tubulose extension part 32 has hollow inside, and extends to the inside of inner tube 14, outer tube 12 and sleeve 26; Described inner tube 14, outer tube 12 are fastened on tubulose extension part 32 together with sleeve 26; Described valve 17 is arranged on described stage casing 22.
