The pipe is stretchable and uniform in structure and will not generate wrinkling angles when stretching or retracting. According to the technical scheme, the pipe is characterized by comprising a pipe body capable of stretching and retracting in the length direction, the pipe wall extends outwards integrally to form a plurality of flexible convex rings when the pipe body is in the natural retracting state, the pipe wall extends inwards integrally to form a plurality of flexible concave rings when the pipe body is in the natural retracting state, and the pipe body of the structure can deform uniformly; during retracting, the outer wall of the pipe is composed of outer walls of the multiple flexible convex rings, the inner wall of the pipe is composed of inner walls of the multiple flexible concave rings, and the shapes are uniform; due to the fact that no irregular wrinkles exist and no sharp wrinkle angles exist, materials inside and outside the pipe or skin will not be scratched; and during stretching, the pipe is in a similar pipe shape, in other words, the inner wall and the outer wall are of the micro wavy structures, the inner and outer wall stress of the pipe can be effectively buffered, the pipe has the good structural strength and can achieve uniform shape deformation, and the good application market is achieved.
Description
Technical field
The present invention relates to a kind of tubing, relate to a kind of tubing, tubing making method and flexible water pipe or rather.
Background technique
General length of pipe and thickness are all changeless, when gard watering, use cumbersome, because when the dried up source, place needing to water is distant, just needs to use longer water pipe, need manually to launch and pack up water pipe before and after using and deposit to facilitate, lose time, and heavy, easy tangled up and knotted, make troubles to staff, also have impact on working efficiency.
For this reason, human hair is had to understand a kind of flexible water pipe, a kind of novel telescopic water pipe as disclosed in the patent No. Chinese utility model patent " flexible water pipe " that is ZL201320634454.5 (notification number is CN203517045U), it is characterized in that: comprise pipe and high strength yarn knit outer in latex, it is outside that described high strength yarn knit outer is enclosed within pipe in latex, forms inside and outside double pipe structure.The advantage that prior art water pipe is compared is: the elasticity that make use of pipe in latex, makes to automatically prolong during water flowing, automatically shrinks, remove the time of artificial closed tube from, raise labour efficiency, and have the protection of knit outer, water pipe long service life when closing water source.
Existing flexible water pipe is double layer construction, and wherein, internal layer is the water pipe that elastic material (latex, TPE, TPU) is made, and skin is the fibre woven pipe of nature fold.During nature of harvesting and storing, the elasticity water pipe of internal layer shrinks, and drives that outer layer fiber woven tube is wrinkling to be reached shortening and harvest and store.During use, the water flowing of internal layer elasticity water pipe, pipe expansion under the pressure of water also drives outer braid pipe to stretch thereupon, and determine water pipe size by the final extended configuration of woven tube, the defect of this water pipe is, outer braid pipe plays restriction water pipe thickness length, and due to outer braid pipe be nature fold, sharper fold angle can be there is, internal layer elasticity water pipe can scratch when the water flowing of internal layer elasticity water pipe is extended by fold angle, by its be flexible water pipe bend time, and due to internal layer elasticity water pipe use due to water-filling after elongated, cause water wall thinning, internal layer elasticity water pipe is more easily damaged, namely after using certain hour, during internal layer elasticity water pipe uses, easily leakage is even ruptured.
Summary of the invention
The technical problem to be solved in the present invention is, provide a kind of scalable, even structure, does not produce the tubing at fold angle time flexible.
Technical solution of the present invention is, a kind of tubing with following structure is provided, comprise telescopic tubing main body along its length, under described tubing main body natural shrinking state, tube wall is integrally outward extended with some flexible bulge loops, and under described tubing main body natural shrinking state, tube wall has integrally extended internally some flexible scrobicular rings.
Preferably, described flexible bulge loop and flexible scrobicular ring are arranged along interval, tubing principal length direction and are connected by linkage section.
Preferably, the external diameter of described flexible bulge loop is 1.5-2.5 times of flexible scrobicular ring internal diameter.
After adopting above structure, tubing of the present invention compared with prior art, have the following advantages: be outward extended with some flexible bulge loops and some flexible scrobicular rings that extended internally by arranging, in other words, namely the tube wall on the longitudinal section under tubing main body natural shrinking state is provided with radial concavo-convex, for arrangement is wavy very closely, the tubing main body of this structure can homogeneous deformation, during contraction, outer pipe wall is made up of some flexible bulge loop outer walls, inwall is made up of some flexible scrobicular ring inwalls, linkage section folds mutually, namely shape approximation is the arc-shaped kick that even ring-type tubing inside and outside wall is provided with evenly arrangement, shape is even, owing to there is no irregular fold, and there is not sharp keen fold angle, the material inside and outside tubing or skin can not be scratched, the external diameter of described flexible bulge loop is 1.5-2.5 times of flexible scrobicular ring internal diameter, make it have larger extending amount, and attractive in appearance being convenient to is received and is gripped, during stretching, extension, tubing is approximately tubulose, namely there is small wavelike structure in inside and outside wall, can effectively cushion tubing inside and outside wall stressed, tubing is made to have good structural strength and the deformation of energy uniform shape, there is good application market, and by described warp, parallel is set to form an angle with hollow rope band medial axis, i.e. warp, parallel is all not parallel with hollow rope band or vertical, when arranging flexible inner tube in the hollow rope band of this structure, the braiding structure of this structure can disperse interior pipe water flowing to expand afterwards and the frictional force of hollow rope band, what make to stretch is more smooth and easy, interior pipe not easy to wear, and hydraulic pressure is higher, axis and the radial expansion of interior pipe are more, hollow rope band is tightened up, structure is tightr, barrier propterty is better, and when hollow rope band is connected with flexible inner tube two ends, when flexible inner tube is under pressure as water flowing, flexible inner tube radial outward expansion and axial elongation, make hollow rope band axial elongation and radially-inwardly tighten up, hollow rope band inwall and flexible inner tube outer wall are conflicted and mutually extrudes, coordinate closely, namely hollow rope band and flexible inner tube coordinate common restriction expansion telescopic extensions, make structural stability, not fragile, improve working life.
