Abstract

The utility model discloses a shower flexible pipe, which comprises an inner metal layer, an outer metal layer and a base, wherein the inner metal layer and the outer metal layer are fixed on the base. The shower flexible pipe is characterized in that a certain spatial clearance is formed between the inner metal layer and the outer metal layer so as to form an annular space which is used for accommodating a metal flexible pipe; and the outer metal layer comprises a metal wire net sleeve. According to the shower flexible pipe provided by the utility model, the metal flexible pipe is assembled through utilizing the annular space formed by the inner metal layer and the outer metal layer, so that the assembling process is simplified, and the connection strength of an outer sleeve of the metal flexible pipe and the metal flexible pipe after assembling is improved, while the shower flexible pipe has the advantages of anti-fatigue and high and low temperature resistance, and further prolongs the service life thereof.

Description

A kind of shower hose

Technical field

The utility model relates to a kind of shower hose, belongs to cleaners and polishes accessory technical field.

Background technique

At present, in the used shower bath in bathroom, be connected flexible pipe between water supply installation and the shower nozzle by metallic hose and place the rubber hose in it to form.The hose coupling structure of existing technology comprises: copper plug, rubber hose, plastic whorl cover, metallic hose, overcoat, sealing gasket; One end of rubber hose is enclosed within copper connection part beyond the Great Wall; The plastic whorl cover is sleeved on the rubber hose, and its fore-end effect is that the connection part with rubber hose and copper plug compresses sealing, and its rear end part has screw thread; Adopt thread connecting mode with metallic hose; At last overcoat is enclosed within on metallic hose and the plastic whorl cover, sealing gasket is arranged on the front end position of copper plug, and whole flexible pipe is linked to each other with other match equipment by nut.There is following deficiency in said structure: when connecting metallic hose; Need at first to spin fixing with metallic hose the plastic whorl cover; Then overcoat is enclosed within metallic hose and plastic whorl puts; Its packaging technology is comparatively complicated, and join strength is not high, and fatigue strength reduction and sealing effect are not good after long-term the use.

Summary of the invention

Complicated for the packaging technology that solves the hose coupling between water supply installation and the shower nozzle, join strength is not high, the not high problem of endurance, sealing effect not; The utility model provides a kind of shower hose; Comprise metallic hose and metallic hose overcoat; Said metallic hose overcoat comprises: inner metal layer, outer metal layer and base, and said inner metal layer is fixed on base with outer metal layer, between said inner metal layer and the said outer metal layer certain spatial joint clearance is set; Form a kind of annular space, be used to put said metallic hose.

Preferably, said inner metal layer has and the corresponding spiral lamination of said metallic hose, and said metallic hose and said metallic hose overcoat spin.

Preferably, can extra additional pressure or industrial glue when said inner metal layer and said outer metal layer spin, said metallic hose is bonded together with said inner metal layer and outer metal layer respectively closely.

The beneficial effect of the utility model is: the metallic hose overcoat and the shower hose that relate in the utility model; Be to utilize the annular space that forms between inner metal layer and the outer metal layer to come the assembling metal flexible pipe; Make packaging technology simplify more, and metallic hose overcoat and the join strength anti-fatigue ability and the sealing effect of metallic hose after the assembling obviously strengthen.

Embodiment

Describe below in conjunction with the preferred embodiment of accompanying drawing, should be appreciated that preferred embodiment described herein only is used for explanation and explains this, and be not used in qualification the utility model the utility model.

Referring to shown in Figure 1; Hose coupling structure comprises copper plug 21, rubber hose 22, and rubber hose 22 is socketed on the connection part of copper plug 21, and this hose coupling also comprises metallic sheath 23; Directly be sleeved on the outside of rubber hose, be used for the joint of rubber hose 22 with the copper plug closely is connected.Wherein the aperture, two ends of metallic sheath is different, and the aperture of one of which end is greater than the external diameter of said rubber hose, and the aperture of the other end is then less than the external diameter of said rubber hose.Outside the said metallic sheath 23, a metallic hose overcoat 25 is set also, said metal-coating 25 directly is connected with metal-coating 24.

Fig. 2, Fig. 3 have illustrated the plan view and the rear view of present embodiment metallic hose overcoat respectively; As shown in the figure; Metallic hose overcoat 25 comprises two metal layers and base 253, and said two metal layers are respectively inner metal layer 252 and outer metal layer 251, and inner metal layer 252 is fixed on the base 253 with outer metal layer 251 1 ends; The diameter of base 253 is greater than the external diameter of outer metal layer 251; Have a through hole on the base 253, its aperture equates with the internal diameter of inner metal layer 252 basically, the gap of interval certain space between inner metal layer 252 and the outer metal layer 251; Form an annular space 254, this annular space 254 is used to put the pipe thickness that space length between metallic hose 24. inner metal layers 252 and the outer metal layer 251 is slightly larger than metallic hose.A through hole is set on the base 253, said through hole can so that metallic sheath 23 pass.Said inner metal layer 252 has and said metallic hose 24 corresponding spiral laminations, and said metallic hose 24 spins with said metallic hose overcoat 25.Can extra additional pressure or industrial glue when said inner metal layer 252 spins with said outer metal layer 251, said metallic hose 24 is bonded together with said inner metal layer 252 and outer metal layer 251 respectively closely.

Fig. 4 is the left view of metallic hose overcoat, and is as shown in the figure, and an end of inner metal layer 252 is separately fixed on the base 253 according to the outer order in back in the elder generation with an end of outer metal layer 251.As preferably, in the present embodiment, base 253 is by turn up bending and forming of inner metal layer 252, and an end of outer metal layer 251 is fixed on the base 253.But the generation type that it will be understood by those of skill in the art that base is not limited thereto, also can be independently and inner metal layer 252 form separately with the form of outer metal layer 251 with component.Inner metal layer 252 can be fixed on the base 253 with welding equijoin mode with outer metal layer 251.

Fig. 5 is the schematic representation after metallic hose overcoat and metallic hose connect; As shown in the figure; Metallic hose screws in by inner metal layer 252 and outer metal layer 251 and connects in the annular space 254 that forms; Then simultaneously to the inner metal layer 252 and outer metal layer 251 application of forces, make can clamp metallic hose after inner metal layer 252 and outer metal layer 251 interactions, metallic hose overcoat 25 and metallic hose 24 are combined closely.In the present embodiment,, also can come bonding metal hose overcoat 25 and metallic hose 24 by extra use glue for the join strength that makes metallic hose overcoat and metallic hose is bigger.
