Embodiment Construction

[0028] According to the invention, the hose is specially designed and manufactured with a spiral appearance, and is characterized in that the hose can be stretched to be particularly long. This may also form a combination with one or more of the characteristics described below. According to the invention, a slight adjustment to the cross-sectional structure of this kind of hose can be manufactured into a spiral hose for a vacuum cleaner.

[0029] In order to make the hose more flexible, the bottom of each section of the concave and convex parts can be made longer, or they can be made thinner or thicker, and then a part of it is hidden in the middle during the manufacturing process. Like picture 1 to Figure 4 Embodied as. The bottom 2 parts of the No. 1 section where "this" is cast and pressed will be cooled and formed after being cast in this form (its shape is like Picture 12 Shown). During the casting process, a part of the bottom 2 will be bent to 180 degrees, and its cent...

Abstract

Disclosed is an elastic flexible pipe capable of flexible telescoping. One surface of the elastic pipe is provided with helical section structures (1, 11, 21) made of plastic materials. A series of components that are mutually connected, sheathed and grouped and helical component structures are fixed in a manner of welding. The section structure of the component is provided with at least one bottom part (2, 12) and at least one frame part (4, 14, 24). The frame part forms the protruding part of the flexible pipe with respect to the bottom part, and plays the role of stabilizing the flexible pipe as respected. Telescopic and unfolding parts (5, 15, 25) are formed by a series of structure components being mutually sheathed and grouped in arrangement and connected. With the arrangement of the telescopic and unfolding parts, the flexible pipe can be stretched and pulled under the function of axial pulling force, and the flexible pipe can be prolonged in length.

Description

Technical field [0001] The invention relates to a flexible flexible hose. Background technique [0002] For example, vacuum cleaners on the market use this flexible plastic spiral hose to suck dust from homes and buildings into the vacuum cleaner. These currently used spiral hoses are made of plastic, and have the characteristics of flexible bending and pressure resistance. (If a person stands on it, it can bounce back and the recovery is more than 95%). Its inner wall is smooth, During the use of the vacuum cleaner, it will not be stuck due to strong suction. [0003] These hoses are cast from cross-sectional structural components that are rolled into spiral series sets. This kind of profile meets and achieves the above-mentioned characteristics with its specific shape. This profile is first cooled and then rolled into a spiral shape with a special tool. During the winding of the spiral winding, a snap device that can be connected to each other is arranged and installed betwee...
