Abstract

The utility model provides a high-pressure hose, belongs to the technical field of sanitary ware accessories, and solves the problems of short service life and the like in the conventional high-pressure hose. The high-pressure hose comprises a plastic inner pipe, wherein a braiding layer wraps the plastic inner pipe and is braided by using high-strength silk threads. The high-pressure hose has the advantages of convenience for connection and installation, long service life and the like.

Description

High pressure hose

Technical field

The utility model belongs to cleaners and polishes accessory technical field, relates to a kind of water inlet and outlet connection pipe fitting, particularly a kind of high pressure hose.

Background technique

At present, the high pressure hose on the market all is made up of plastic inner pipe and metal outer pipe, and in metal outer pipe was coated on plastic inner pipe tightly, metal outer pipe was metal bellows or is formed by steel band braiding.There are some shortcomings in this high pressure hose: 1, metal outer pipe is soft, in use not flexible inadequately, in use is not easy to be connected with the turnover water pipe layout; 2, the plastic inner pipe star variable in the bending part of metal outer pipe is big, the easy ageing fracture, and working life is short.

To above-mentioned problem, people have designed various high pressure hoses, and some has also applied for patent, and for example the Chinese patent documents and materials disclose a kind of shower hose [application number: 201120055822.1; Notice of authorization number: CN202032194U]; It comprises the pipe joint at metal outer pipe, interior pipe and two ends; Metal outer pipe is fixedly sleeved outside interior pipe; Metal outer pipe is coupled to each other by number of metal joint button and forms, and the pitch value of the adjacent metal joint button when contraction or stretching is set at 0.2 to 0.3 times of metal outer pipe diameter, and the metal joint is detained the left and right sides and had in-flanges and flanging; Through in-flanges and the mutual snapping of flanging, the in-flanges of mutual snapping and the length L of flanging are 0.08 to 0.09 times of metal outer pipe diameter between the metal joint button.

The tension of above-mentioned shower hose, antitorque and resistance to bending have obtained certain raising; But still exist metal outer pipe not flexible, in use be not easy to the problem that is connected with intake pipe; And the cost of metal outer pipe is higher in the above-mentioned patent; Also higher to making processing request, processing is inconvenience comparatively.

Summary of the invention

The purpose of the utility model is to the problems referred to above that exist in the existing technology, provides a kind of pliability good high pressure hose.

The purpose of the utility model can realize through following technical proposal: a kind of high pressure hose, comprise plastic inner pipe, and it is characterized in that the described plastic inner pipe outside is coated with braid, described braid is formed by high-strength silk thread braiding.

Braid is formed by the price high-strength silk thread braiding cheap than steel band in this high pressure hose, and low cost of manufacture is easy to process; High-strength in addition silk thread has good mechanical strength, and not easy-rupturing, so braid can bear the bigger pressure of plastic inner pipe, long service life; High-strength silk thread also has good pliability, guarantees that like this pliability of braid is good, and this high pressure hose can be arbitrarily crooked when being connected with turnover water pipe, connects arrangement convenience.

In above-mentioned high pressure hose, the described braid outside is coated with plastic outer tube.Plastic outer tube has the effect of protection braid, and in use plastic outer tube bears cutting of sharp object and draws, and braid can not cut off, and has prolonged the working life of this high pressure hose.

In above-mentioned high pressure hose, described plastic outer tube is the transparent plastic outer tube.In actual the manufacturing, high-strength silk thread is woven into various patterns attractive in appearance, and the transparent plastic outer tube can not block braid pattern attractive in appearance, conveniently selects the consumer to appreciate, buy.

In above-mentioned high pressure hose, described high-strength silk thread is high-tenacity terylene line or polyamide fibre line or nylon thread or flax fiber line.

Compared with prior art; The low cost of manufacture of this high pressure hose; The braid that is formed by high-strength silk thread braiding makes that the pliability of this high pressure hose is good, and connection is convenient, smooth surface; Can not injure hand, good mechanical strength of high-strength in addition silk thread and plastic outer tube have guaranteed that also this high pressure hose has long working life.

Description of drawings

Fig. 1 is that the structure of this high pressure hose is partly cutd open schematic representation.

Fig. 2 is the schematic cross-section of this high pressure hose.

Among the figure, 1, plastic inner pipe; 2, braid; 3, plastic outer tube.

Embodiment

Below be the specific embodiment of the utility model and combine accompanying drawing, the technological scheme of the utility model is done further to describe, but the utility model is not limited to these embodiments.

As depicted in figs. 1 and 2, this high pressure hose comprises plastic inner pipe 1, and plastic inner pipe 1 outside is coated with by high-strength silk thread braiding and forms braid 2, and braid 2 outsides also are coated with plastic outer tube 3.High-strength silk thread is high-tenacity terylene line or polyamide fibre line or nylon thread or flax fiber line; High-strength silk thread is the high-tenacity terylene line in the present embodiment; During actual the manufacturing; Be woven into the high-strength line of white polyester closely that waffle-like pattern is coated on plastic inner pipe 1 outside, can on the high-strength line of white polyester, work out out various patterns with the high-tenacity terylene line of other color more as required afterwards, plastic outer tube 3 is the transparent plastic outer tube; Plastic outer tube 3 can not block braid 2 pattern attractive in appearance like this, conveniently selects the consumer to appreciate, buy.

Braid 2 is formed by the price high-tenacity terylene line braiding cheap than steel band in this high pressure hose, and low cost of manufacture is easy to process; The high-tenacity terylene line has good mechanical strength in addition, and not easy-rupturing, so braid 2 can bear the bigger pressure of plastic inner pipe 1, long service life; The high-tenacity terylene line also has good pliability, guarantees that like this pliability of braid 2 is good, and this high pressure hose two ends are fixed with joint, and this high pressure hose can be arbitrarily crooked as required when being connected with turnover water pipe, connects arrangement convenience.Plastic outer tube 3 also has the effect of protection braid 2, and in use plastic outer tube 3 bears cutting of sharp object and draws, and braid 2 can not cut off, and has prolonged the working life of this high pressure hose.

Specific embodiment described herein only is that the utility model spirit is illustrated.The utility model person of ordinary skill in the field can make various modifications or replenishes or adopt similar mode to substitute described specific embodiment, but can't depart from the spirit of the utility model or surmount the defined scope of appended claims.

Although this paper has used terms such as plastic inner pipe 1, braid 2, plastic outer tube 3 morely, do not get rid of the possibility of using other term.Using these terms only is in order to describe and explain the essence of the utility model more easily; It all is contrary with the utility model spirit being construed to any additional restriction to them.
