Description
Technical field
The utility model relates to bathroom shower equipment, particularly a kind of hose coupling.
Background technique
At present, in the used shower bath in bathroom, be connected flexible pipe between water supply installation and the shower head by metal outer pipe 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, metal outer pipe 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 metal outer pipe 14, at last, overcoat 15 is enclosed within on metal outer pipe 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: because an end of rubber hose entangles the joint of copper plug, for better sealing, the diameter of general joint is greater than rubber hose 12, therefore when rubber hose 12 is enclosed within the joint of copper plug 11, the nozzle diameter of rubber hose is stretched and becomes big herein, make the rubber hose attenuation, leak because of friction or oxidation come off or break easily, cause the operating life of whole flexible pipe to shorten; Because it is the joint of copper plug is generally shorter herein, therefore insecure in addition with being connected of rubber hose, cause easily to come off, and if joint is done longly, difficulty comparatively in the time of assembling.
The model utility content
At the problems referred to above, the utility model provides a kind of hose coupling, comprises copper plug, rubber hose, and described copper plug includes a junction, and described rubber hose is socketed on the joint of described copper plug, and wherein, described hose coupling also comprises:
Metallic sheath is positioned at the described rubber hose outside, is used for the joint and the described rubber hose of described copper plug are compressed sealing.
In the utility model owing to used metallic sheath, can prevent effectively that rubber hose from occurring because of leaking of coming off or break and cause, also can significantly improve the join strength of copper plug joint and rubber hose, improved the stability and the operating life of whole flexible pipe, and this hose coupling also is convenient to assembling.
Description of drawings
Fig. 1 is the hose coupling structure figure of prior art;
Fig. 2 is hose coupling structure figure of the present utility model;
Fig. 3 A to Fig. 3 C is the assembling schematic representation of hose coupling.
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.
Wherein, preferred described rubber hose 22 is outer to be had netted or protective layer such as helical, and it can protect rubber hose, makes it be difficult for breaking or oxidation.
Can also be provided with plastic whorl cover and overcoat in the outside of metallic sheath 23, be used to connect metal outer pipe.Preferably, as shown in this embodiment, overcoat 25 is made the double-level-metal layer, the space between its double-level-metal cover holds metal outer pipe 24, and overcoat 25 and metal outer pipe 24 are by punching press or glue strong bonded together.
Sealing gasket 26 on the front end sleeve of copper plug 21, link to each other with water source or other devices by nut (not shown) or other connection parts.
The present invention is described in detail referring now to Fig. 3 A to Fig. 3 C.
At first, as shown in Figure 3A, metallic sheath 23 is enclosed within on the rubber hose 22, the wherein aperture of an end of metallic sheath 23 is slightly larger than the external diameter of rubber hose 22, therefore is easier to metallic sheath is enclosed within on the rubber hose 22; The aperture of metallic sheath 23 the other ends is less than the external diameter of rubber hose 22, so this end can withstand the end of rubber hose 22, and rubber hose is not exposed;
Secondly, shown in Fig. 3 B, the joint of copper plug 21 is inserted rubber hose 22, the internal diameter of the diameter of the joint of copper plug 21 and rubber hose 22 about equally, therefore be easier to the joint of copper plug is inserted rubber hose 22, and do not need the nozzle diameter of rubber hose is stretched change greatly, then use the mode of for example punching press, to the P that exerts pressure simultaneously around the metallic sheath, make the joint of copper plug 21 closely be connected with rubber hose 22.Preferably, the joint of copper plug 21 comprises a plurality of annular projections, can increase the frictional force between joint and the rubber hose and be connected tightness; Preferred, can do the length of the joint of copper plug 21 longer, its length can be greater than 1cm, because the internal diameter of the diameter of joint and rubber hose about equally, therefore in assembling, be easy to rubber hose is socketed on the copper plug joint, reduced the assembling difficulty, simultaneously, because the length of copper plug joint is longer, the length that it is connected with rubber hose can be increased, the intensity of connection can be increased like this.
At last, as Fig. 3 C, can put overcoat 25 in metallic sheath 23 outsides, overcoat 25 is connected with metal outer pipe 24; Sealing gasket 26 on the front end sleeve of copper plug; Last whole flexible pipe links to each other with water source or other devices by nut or other connection part.
The utility model is because of adopting metallic sheath, can be about equally with the diameter (concrete is the internal diameter of flexible pipe) of the diameter of the joint of copper plug and rubber hose, therefore the nozzle diameter of rubber hose need not be stretched and become big, rubber hose also can attenuation, the situation that the rubber hose that therefore can avoid this place comes off or breaks and leak because of friction or oxidation.
By for example stamping process, the joint of copper plug closely is connected with rubber hose simultaneously, can plays the effect that is difficult for the loss rubber hose in the time of strict seal again, and compact structure, mounting process is simple, and is easy to assembly, improves the operating life and the stability of whole flexible pipe.
In a word, the above is preferred embodiment of the present utility model only, is not to be used to limit protection scope of the present invention.Within the spirit and principles in the present invention all, any modification of being done, be equal to replacement, improvement etc., all should be included within protection scope of the present invention.
