Abstract

The utility model discloses a metal hose sleeve and a shower hose thereof, wherein the metal hose sleeve comprises an inner metal layer, an outer metal layer and a base; the inner metal layer and the outer metal layer are fixed on the base, wherein the inner metal layer is separated from the outer metal layer with a certain interval, thus forming an annular space, and the annular space is used for containing the metal hose. The metal hose sleeve utilizes the annular space formed between the inner metal layer and the outer metal layer to assemble the metal hoses, thus greatly simplifying the assembly process; and after assembly, the joint strength between the metal hose sleeve and the metal hoses is very high.

At present, in the used shower bath in bathroom, be connected flexible pipe between water supply installation and the shower head by metallic hose and place the rubber hose in it to form.Existing hose coupling structure as shown in Figure 1, its structure comprises: copper plug 11, rubber hose 12, plastic whorl cover 13, metallic hose 14, overcoat 15, sealing gasket 16, one end of rubber hose 12 entangles the joint on the copper plug 11, plastic whorl cover 13 is enclosed within on the rubber hose 12, its fore-end is used for the joint of rubber hose 12 and copper plug 11 is compressed sealing, its rear end part has screw thread, be connected with metallic hose 14, at last, overcoat 15 is enclosed within on metallic hose 14 and the plastic whorl cover 13, sealing gasket 16 is arranged on the front end of copper plug 11, and whole flexible pipe is linked to each other with water source or other devices by nut 17.

Adopt the deficiency of prior art constructions to be: when connecting metallic hose, need at first the plastic whorl cover to be spun with metallic hose, overcoat 15 is enclosed within on metallic hose 14 and the plastic whorl cover 13 then, and its packaging technology is comparatively complicated, and join strength is not high.

The model utility content

At the problems referred to above, the utility model provides a kind of metallic hose overcoat, comprise inner metal layer, outer metal layer and base, inner metal layer is fixed on the base with outer metal layer, the certain distance in interval between wherein said inner metal layer and the described outer metal layer, form an annular space, be used to hold metallic hose.

The present invention simultaneously also provides a kind of shower hose, comprises metallic hose, the metallic hose overcoat; The metallic hose overcoat further comprises inner metal layer, outer metal layer and base, inner metal layer is fixed on the base with outer metal layer, wherein, and the certain distance in interval between described inner metal layer and the described outer metal layer, form an annular space, be used to hold metallic hose.

Metallic hose overcoat and shower hose in the utility model, utilize between inner metal layer and the outer metal layer and to form annular space and come the assembling metal flexible pipe, make packaging technology simplify greatly, and the join strength of assembling back metallic hose overcoat and metallic hose strengthen greatly.

Description of drawings

Fig. 1 has illustrated the hose coupling structure figure of prior art;

Fig. 2 has illustrated hose coupling structure figure of the present utility model;

Fig. 3 A to Fig. 3 D has illustrated the structural representation of metallic hose overcoat;

Fig. 4 has illustrated the schematic representation that the metallic hose overcoat combines with metallic hose.

Embodiment

For making the purpose of this utility model, technological scheme and advantage clearer, below with reference to the accompanying drawing embodiment that develops simultaneously, the utility model is further described.

Referring to shown in Figure 2, hose coupling structure comprises copper plug 21, rubber hose 22, and rubber hose 22 is socketed on the joint of copper plug 21, and this hose coupling also comprises metallic sheath 23, be located immediately at rubber hose 22 outsides, be used for the joint of rubber hose 22 with the copper plug is tightly connected.Aperture, the two ends difference of metallic sheath 23 wherein, the aperture of one end be greater than the external diameter of described rubber hose, and the aperture of the other end is then less than the external diameter of described rubber hose.Outside metallic sheath 23, also be provided with metallic hose overcoat 25, this metallic hose overcoat 25 directly is connected with metallic hose 24.

Below with reference to Fig. 3 A to 3D the metallic hose overcoat is elaborated.

Fig. 3 A has illustrated the three-dimensional structure diagram of present embodiment metallic hose overcoat, as shown in the figure, metallic hose overcoat 25 comprises two metal layers and base 253, be respectively inner metal layer 252 and outer metal layer 251, inner metal layer 252 is fixed on the base 253 with an end of outer metal layer 251, the diameter of base 253 is greater than the external diameter of outer metal layer 251, has a perforate on the base 253, the internal diameter of its aperture and inner metal layer 252 about equally, the certain distance in interval between inner metal layer 252 and the outer metal layer 251, form an annular space 254, this annular space 254 is used to hold metallic hose 24.Distance between inner metal layer 252 and the outer metal layer 251 is slightly larger than the pipe thickness of metallic hose.

Fig. 3 B is the plan view of metallic hose overcoat 25, and as shown in the figure, inner metal layer 252 surrounds an annular space 254 with outer metal layer 251;

Fig. 3 C is the worm's eye view of metallic hose overcoat 25, as shown in the figure, has a perforate on the base 253, and this perforate can be so that metallic sheath 23 passes.

Fig. 3 D is the side view of metallic hose overcoat 25, and as shown in the figure, an end of inner metal layer 252 is separately fixed on the base 253 with an end of outer metal layer 251.Preferably, in the present embodiment, base 253 is outwards bent and is formed by inner metal layer 252, and an end of outer metal layer 252 is fixed on the chassis 253.But the generation type that it will be appreciated by those skilled in the art that base is not limited thereto, and also can be independent of inner metal layer 252, outer metal layer 251 and independent formation, and inner metal layer 251 is formed on the base 253 with the mode that outer metal layer 252 can weld.

Fig. 4 is the schematic representation that the metallic hose overcoat is connected with metallic hose, as shown in the figure, metallic hose inserts in the annular space that is formed by inner metal layer 252 and outer metal layer 251, then simultaneously to the inner metal layer 252 and outer metal layer 251 application of forces, make inner metal layer 252 and outer metal layer 251 can clamp metallic hose, metallic hose overcoat 25 closely is connected with metallic hose 24.In this enforcement, also can additionally use glue to come bonding metal hose overcoat 25 and metallic hose 24.

In order further to increase the join strength of metallic hose overcoat 25 and metallic hose 24, can on inner metal layer 252, spiral lamination be set, this spiral lamination is corresponding with metallic hose, when assembling, metallic hose is screwed in annular space 254 by this spiral lamination, also can make its join strength bigger additionally with pressurization or use glue.

According to the structure of present embodiment, the packaging technology of metallic hose overcoat and metallic hose is simplified greatly, and its join strength strengthens greatly simultaneously.
