が低い問題点を有していた。(Problems to be Solved by the Invention) However, in the conventional flexible fluororesin hoses, whether the outer peripheral surface is formed into a spiral shape or a bellows shape, these are all molded. If a mold was not used, the ridges and valleys would be cut out using a lathe to manufacture an expandable expansion joint, which would require a great deal of labor and time and be expensive. Not only that, but it also had the problem of low flexibility.

る。(Means for Solving the Problems) The present invention was developed as a result of research to solve the above problems. After fitting a large diameter (mountain diameter) retaining ring, heating the gap between the retaining rings, and only by heating processing, the hose can be removed. A flexible hose was successfully obtained by shrinking and deforming the outer periphery into a U-shaped longitudinal section.

Reference numeral 1 is a hose (cheap) molded from a heat-shrinkable fluororesin material, and hollow retaining rings 2.2 are first attached to the inner peripheral surface of the hose 1 at regular intervals. After opening and fixing, heat the outer circumferential surface of the hose between retaining rings 2.2 with heater A in sequence, and when each hose reaches its shrinkage temperature (approximately 120 degrees), the outer circumferential surface of the hose between retaining rings 2.2 As shown in FIG. 1, the retaining ring 2.3 has a U-shaped outer circumferential surface 3.3 that is inwardly recessed in a U-shaped longitudinal section.

Large objects can be easily manufactured by hand, and it is possible to handle various types of uniform products with different shapes.By selecting the material of the hose, the amount of depression on the outer circumferential surface of the U-shaped diameter can be adjusted to different sizes. You can easily create things with great flexibility and elasticity, and the heating time is only a few seconds! Since a U-shaped valley outer peripheral surface is formed, mass production is possible, and since no equipment is required, manufacturing is extremely easy, and the invention has the effect of significantly lowering product costs compared to molding and machining. It is.
