Description

Irrigation plastic hose

Technical field

This utility model belongs to the technical field of agricultural irrigation equipment, is specifically related to a kind of irrigation plastic hose.

Background technology

Conventional plastic water band (particularly PE water band) is widely used in the irrigation system of agricultural planting.Conventional plastic water band is laid in behind plantation place, at scene of irrigating, water band tube wall must be punched (drilling through installing hole) by peasant household, and install water guide pipe fitting (such as leading directly to pipe fitting, tee pipe fitting) at position of mounting hole, in order to water is drawn from tee pipe fitting, distributes.

The structure of common traditional water guide pipe fitting and occupation mode are as shown in Figure 1.Water guide pipe fitting 30 is formed with annular groove 301, the point diameter of water guide pipe fitting 30 is slightly larger than the diameter of the installing hole 211 of tube wall 2, the front end of water guide pipe fitting 30 is formed with screw thread or tapering, during installation, the front end of water guide pipe fitting is by force by temporary transient for installing hole 211 distending, makes the tube wall edge of installing hole 211 fill in annular groove 301.But aforesaid way exists following not enough: when water band use every time complete need to regain time, whether water guide pipe fitting 30 pulls out and there is dilemma: if pulling out water guide pipe fitting, when then next time uses, it is necessary for inserting water guide pipe fitting by force, but the installing hole of plastic hose is actually difficult to bear and the most so tosses to and fro, the edge of installing hole splits during being easy to extract insertion back and forth twice 1 or damaged, so that being difficult to be formed to seal with the front end of water guide pipe fitting again coordinate；Otherwise but, if not pulling out water guide pipe fitting 30, then regain water band can not be rolled up, this is because, water guide pipe fitting 30 is owing to needing to realize certain function (be such as provided with shower nozzle, or need to realize fastening socket with water pipe), therefore the axial length of water guide pipe fitting needs longer (generally more than 5 cm), and its radius is little, it appears relatively loftier and the most flat, therefore in the case of with water guide pipe fitting, water band can not be regained and wound up.

Because the problems referred to above, applicant once proposed a kind of patent application irrigating use plastic hose on April 26th, 2014, Application No. 201420206774.5, its structure is as shown in Figure 2, connect plastic nut 11 installing hole 211 position of plastic hose tube wall 21 is fixing, and water guide pipe fitting is arranged on the screw 13 of plastic nut, realizes water guide；When plastic hose 21 use complete need regain time, water guide pipe fitting can be twisted away, the most remaining plastic nut 11 is stayed on plastic hose tube wall 21；The function of twist-on water guide pipe fitting only need to be played due to plastic nut, thus its axial length can be made to the shortest, and the diameter of plastic nut is big compared with the diameter of water guide pipe fitting front end, diameter plus plastic nut convex annular edge is the biggest, therefore plastic nut seems the most flat (with traditional water guide pipe fitting comparatively speaking), therefore plastic nut will not hinder plastic hose realization curling (winding), i.e. the water band with plastic nut to wind up.When plastic hose needs to use next time, only need unwinding and be screwed water guide pipe fitting, then can screw on plastic stopper without the position distributing water outlet.

But recently, applicant finds in practice, above-mentioned irrigation plastic hose is owing to being arranged on the convex annular of plastic nut edge in the tube chamber of plastic hose, therefore the cross section of plastic hose tube wall must need the overlapping part 24 that there are shown in Fig. 2, first plastic nut 11 to be passed the installing hole 211 of plastic hose tube wall before overlap joint, the most just couple together fixed for overlapping part 24, otherwise, if plastic hose tube wall not there are the overlapping part 24 that can open wide in advance, then the convex annular of plastic nut is along being fit in the tube chamber of plastic hose.Owing to above-mentioned irrigation plastic hose there are overlapping part 24, and easily there is the hidden danger of water leakage due to aging or bonding fastening in this overlapping part.

Utility model content

The purpose of this utility model is to overcome disadvantages mentioned above to provide a kind of irrigation plastic hose, and it can reclaim easily and wind, and plastic hose tube wall is not easy leakage.

Its purpose can be realized by below scheme: this irrigation plastic hose includes that the tube wall that plastic material makes, tube wall central part are formed as tube chamber；Tube wall offers multiple through hole, and each through hole correspondence is supporting is provided with a plastic nut, and the axial length of plastic nut is 0.7-2.0 centimetre, and plastic nut body center is formed with screw, and the screw of each plastic nut body is directed at corresponding tube wall through hole；Plastic nut integrated injection molding forms oriented surrounding and highlights the convex annular edge of extension, it is characterised in that: convex annular along being positioned at outside the tube chamber of plastic hose, the outer surface of tube wall welding or bonding of the lower surface on convex annular edge and plastic hose through hole marginal area；Plastic nut body also is located at outside the tube chamber of plastic hose.

It is preferred that the convex annular of plastic nut uses ultrasonic fusing along with plastic hose tube wall.

This utility model has the following advantages and effect:

One, this utility model is at the fixing plastic nut that connects of position of mounting hole of plastic hose tube wall, and water guide pipe fitting (such as Three-way Union, plastics bypass elbow, plastics straight coupling etc.) or sealing pipe fitting is arranged on plastic nut and realizes water guide or sealing；When plastic hose use complete need regain time, water guide pipe fitting or sealing pipe fitting can be twisted away, the most remaining plastic nut is stayed on plastic hose；The function of twist-on water guide pipe fitting only need to be played due to plastic nut, thus its axial length can be made to the shortest, and the diameter of plastic nut is big compared with the diameter of water guide pipe fitting front end, diameter plus plastic nut convex annular edge is the biggest, therefore plastic nut seems the most flat (with traditional water guide pipe fitting comparatively speaking), therefore plastic nut will not hinder plastic hose to realize winding, the i.e. water band with plastic nut can wind up (it is true that water band of the present utility model is dispatching from the factory and sales process just can be in reeling condition).When plastic hose needs to use next time, only need unwinding and be screwed water guide pipe fitting, then can screw on plastic stopper without the position distributing water outlet.

Two, owing to convex annular is along being positioned at outside the tube chamber of plastic hose, the outer surface of tube wall welding or bonding of the lower surface on convex annular edge and plastic hose through hole marginal area, therefore without requiring the tube wall head and the tail overlap joint of plastic hose in processing technology, mean can integrally extrude or be woven to one in the circumferential, because of without leaking because there is overlapping part.
