Description
Technical field
The invention belongs to cleaners and polishes accessory technical field, especially relate to a kind of shower hose.
Background technique
At present, the structure of shower hose is made up of snakelike metal outer pipe and the interior pipe that is provided with in it, metal outer pipe is by plug scyewed joint in the plastics, establish fixing interior pipe of copper inner core in interior the plug, the pitch density that the metal of metal outer pipe saves between detaining is dredged (pitch value is about 5.4mm), and it is more shallow to detain pin (the common 0.8mm of being of fastening length) between adjacent metal saves and detains, the power that links closely is not strong, the pulling force and the torsion that can bear are less, plug scyewed joint in metal outer pipe and the plastics, and working life is shorter.
Summary of the invention
At the problems referred to above of prior art, the invention provides a kind of shower hose that can bear big pulling force and torsion and have resistance to bending.
For achieving the above object, the technical solution used in the present invention is as follows:
A kind of shower hose, the pipe joint that comprises metal outer pipe, interior pipe and two ends, metal outer pipe is fixedly sleeved outside interior pipe, it is characterized in that described metal outer pipe is coupled to each other by number of metal joint button forms, the pitch value of the adjacent metal joint button when contraction or stretching is set at 0.2~0.3 times of metal outer pipe diameter, the metal joint button left and right sides has in-flanges and flanging, by in-flanges and the mutual snapping of flanging, the in-flanges of mutual snapping and the length L of flanging are 0.08~0.09 times of metal outer pipe diameter between the metal joint button.
As preferably, the pitch value of adjacent metal joint button is set at 0.21 times of metal outer pipe diameter when shrinking, and the pitch value of adjacent metal joint button is set at 0.27 times of metal outer pipe diameter during stretching.The inventor finds to have more excellent tension torsional property.
As a kind of preferred enforcement, be 14mm with the diameter of metal outer pipe, above-mentioned pitch value is 3.8mm when stretching.
Further, the pipe joint at two ends comprises the tapered cap that is connected with gondola water faucet, the copper core that is used for pipe in the mount, plug and larynx cover in the steel, the other end is the hexagonal nuts that is connected with water tap, the copper core that is used for pipe in the mount, plug and larynx cover in the steel, plug and larynx cover compresses the inside and outside both sides of metal outer pipe respectively in the steel, inner tube portion shape and copper core are suitable, the copper core has annular convex shoulder, the tapered cap inwall has annular boss, hexagonal nuts has annular boss, plug is fixed between the annular boss of annular convex shoulder and tapered cap inwall with the internal expansion type punching press in the steel of one end, and plug is fixed between the annular boss of annular convex shoulder and hexagonal nuts inwall with the internal expansion type punching press in the steel of the other end.
As further optimization,, be provided with gasket seal in tapered cap and the hexagonal nuts for improving sealing to above mode of execution.
Compare with the prior art shower hose, shower hose of the present invention has following technique effect:
1. shower hose pitch value of the present invention shortens nearly 40% than prior art, the pitch value of the most common flexible pipe is about 5.4mm; The pitch value of shower hose of the present invention is 3.8mm), the metal outer pipe high density designs of shower hose of the present invention can be born more powerful pulling force, the tradition flexible pipe pulling force that can bear is general≤500N, can reach 1000N and shower hose of the present invention can bear pulling force, so the user have stronger independence and Security.
2. the metal outer pipe of shower hose of the present invention is two steel bushing punching presses by plug and larynx cover in the steel, and can bear bigger torsion: experiment shows that with traditional flexible pipe, the user applies certain collapsing force, and flexible pipe will be threaded off at once; And the torsion that uses shower hose of the present invention to bear is more than 2 times of traditional flexible pipe; Shower hose of the present invention has stronger resistance to bending, and the bending failure power that traditional flexible pipe can bear is≤300N, and the counter-bending collapsing force of this shower hose of the present invention can reach more than the 600N, has therefore further strengthened user's Security and reliability.

Embodiment
Embodiment 1,
Shown in accompanying drawing 1-4, shower hose of the present invention comprises the pipe joint at metal outer pipe 6, interior pipe 4 and two ends, and metal outer pipe is fixedly sleeved outside interior pipe 4. interior pipe 4 is a liquid chunnel.
Described metal outer pipe is coupled to each other by number of metal joint button and forms, and the diameter of present embodiment metal outer pipe is 14mm, and the pitch value of adjacent metal joint button is 3.8mm when stretching, and is 3mm when contraction state.
The metal joint button left and right sides has in-flanges and flanging, metal saves between the button by in-flanges and the mutual snapping of flanging, the in-flanges of snapping and the length L of flanging are 1.2mm mutually, see Fig. 5 and Fig. 6, the shower hose of prior art, the pitch value of its adjacent metal joint button is 5.4mm when stretching, and the in-flanges of snapping and the length L of flanging are 0.8mm mutually.
