Cooperation of being full of is fixedly attached on the middle section of outer tube and adapter of plastic, and copper core includes insertion portion and the first flange, insertion section
Divide in insertion inner tube and by clamping the end of inner tube in-between, wherein first with the cooperation of the transition of adapter of plastic
Flange, the second flange and third flange are sequentially stacked, and nut is movably set on outer tube and has to be cooperated with third flange
The 4th flange extended radially inwardly.
Further, the end face of copper core is socketed with gasket.
Further, there are several ring-shaped steps on the outer surface of the insertion portion of copper core.
Further, the nut for the joint assembly connecting with shower is horn-like nut.
Further, the outer surface of horn-like nut is equipped with an annular groove, and the annular groove is anti-skidding for receiving one
Circle.
The utility model by adopting the above technical scheme, has the beneficial effect that the utility model assembling process is simple, subtracts
Low cost of labor, and without using pipe expander, mold loss is avoided, the cost of joint assembly is relatively low, connector
Partial resistance to pressure is higher, is not easy to disengage.
Detailed description of the invention
To further illustrate each embodiment, the utility model is provided with attached drawing.These attached drawings are in the utility model discloses
A part of appearance mainly to illustrate embodiment, and can cooperate the associated description of specification former come the running for explaining embodiment
Reason.Cooperation refers to these contents, and those of ordinary skill in the art will be understood that other possible embodiments and sheet are practical new
The advantages of type.Component in figure is not necessarily to scale, and similar component symbol is conventionally used to indicate similar component.
Fig. 1 is the schematic diagram of the Large Diameter Pipeline shower hose of the prior art；
Fig. 2 is the schematic diagram of the Large Diameter Pipeline shower hose of the utility model.
Specific embodiment
Now in conjunction with the drawings and specific embodiments, the present invention will be further described.
As shown in Fig. 2, a kind of Large Diameter Pipeline shower hose 1 includes inner tube 10, outer tube 20 and joint assembly 30, inner tube 1 is straight
The rubber tube that 11 millimeters of diameter, the double button pipes of the stainless steel that outer tube 2 is 16 millimeters of diameter.The joint assembly 30 include from inside to outside according to
Copper core 310, adapter of plastic 320, steel bushing 330 and the nut 340 of secondary arrangement.Copper core 310 includes insertion portion 311 and the first flange
312.The insertion portion 311 of copper core 310 is inserted into inner tube 10 by interference fit and passes through the transition with adapter of plastic 320
324 cooperations clamp the end of inner tube 10 in-between.Preferably, there are several rings on the outer surface of insertion portion 311
Shape step 3111, to prevent insertion portion 311 to be detached from from inner tube 10.In the shown embodiment, the end face of copper core is socketed with gasket
350, gasket 350 prevents from revealing for sealing.Certainly, gasket 350 is also possible to accessory, when Large Diameter Pipeline shower hose 1 is installed
It uses.
Adapter of plastic 320 includes threaded portion 321, middle section 322 and the second flange 323 of outer diameter from small to large.Its
In, the internal diameter of threaded portion 321 is smaller than the internal diameter of middle section 322 and has transition 324, i.e. threaded portion between the two
Divide between 321 inner wall and the inner wall of middle section 322 not forming a step instead of, forms an inclined-plane.322 He of middle section
The internal diameter of second flange 323 is identical.When threaded portion 321 and outer tube 20 are threadedly engaged, middle section 322 is outer with outer tube 20
Surface is substantially flush.
Steel bushing 330 includes main part 331 and third flange 332.Main part 331 is socketed in outer tube by interference fit
20 and adapter of plastic 320 middle section 322 on.When Large Diameter Pipeline shower hose assembles, the first flange 312, the second flange 323
It is sequentially stacked with third flange 332.Nut 340 is movably set on outer tube 20 and has the diameter cooperated with third flange 332
To the 4th flange 341 to extend internally.4th flange, 341 one side is for limiting, on the other hand for preventing from falling from outer tube 20
Out.In the shown embodiment, the nut 340 for the joint assembly connecting with shower is horn-like nut.Preferably, horn-like nut
340 outer surface is equipped with an annular groove 342, and the annular groove 342 is for receiving an antislip ring 343.
Now briefly explain the assembling process of the Large Diameter Pipeline shower hose of the utility model.Firstly, by 340 activity of nut
It is set on the outer tube 20 for having put on inner tube 10, is then set in steel bushing 330 on the end of outer tube 20, then by adapter of plastic
320 threaded portion 321 is screwed into outer tube 20, so that adapter of plastic 320 is combined together with outer tube 20 and steel bushing 330, finally
Copper core 310 is inserted into after inner tube 10 and is directly compressed copper core 310 with tube press machine.Entire assembling process is very simple, is not necessarily to
Using pipe expander, reduce cost of labor, and without using pipe expander, avoid mold loss, in addition, joint assembly at
