The utility model discloses utilize big camber arc crest wall so that the left side wall is rolled over right the lateral wall or is kept away from the right side wall, and then realize that pipe the folding of corrugated pipe draws in or extend, corrugated pipe's design ability when having improved the extension, in the preparation the utility model discloses a die sinking cost greatly reduced has saved the cost, has improved the yield.

Description

A kind of Telescopic corrugated pipe

Technical field

This utility model is related to a kind of plastic film capicitor of scalable sizing.

Background technology

Plastic film capicitor is a kind of purposes ventilation, aerofluxuss, drainage component widely, for super bath, aerarium, water It is even more a kind of than indispensable connection member for groove, washing machine and smoke extractor etc..The key character of plastic film capicitor is outside Under power, it is extending, shrink and bend, to meet the requirement of various occasions.

At present conventional corrugated tube arranges the flex point for being convex to inside on the wall of side wherein, its objective is to be used in outer masterpiece Under, side wall bends from flex point, so as to realizing extending or shrinking.But the die sinking for making this corrugated tube is relatively costly, thick Inflection portions on mould are carried out with retrofit, how in the die sinking cost for reducing corrugated tube, while protecting after processing The using effect of card corrugated tube becomes those skilled in the art's research emphasis.

Utility model content

For problems of the prior art, the purpose of this utility model is to provide a kind of telescopic corrugated flexible hose.

A kind of telescopic corrugated flexible hose of this utility model, it includes：Ripple type body, the body two ends have connection Portion, body is alternately connected to form continuous ripple type, institute successively by left side wall, arc crest wall, right side wall and arc-shaped wave valley wall State transition in smoothing junction, arc crest wall between left side wall, the arc crest wall, the right side wall and the arc-shaped wave valley wall Radius of curvature be more than 1mm, the linear section shape of right side wall or in outside body protrude arc, left side wall be in body evagination The arc for going out.

Further, the radius of curvature of the arc of the left side wall is 60-200mm.

Further, the radius of curvature of the arc of the right side wall is 60-200mm.

Further, radius of curvature of the radius of curvature of the arc of the right side wall more than the arc of the left side wall.

Further, the line of the right side wall two-end-point and the angle of the body axis are 45 °.

Further, the continuous angle with the body axis of the left side wall two-end-point is 50 ° -75 °.

Telescopic corrugated flexible hose of the present utility model has the beneficial effect that：Using deep camber arc crest wall so as to a left side Side wall is folded to right side wall or away from right side wall, and then realizes that the folding of pipe corrugated flexible hose is drawn in or extended；Improve elongation When corrugated flexible hose style-ability；It is that die sinking cost is substantially reduced this utility model is made, saves cost, improves finished product Rate.

Specific embodiment

Below in conjunction with the accompanying drawings, specific embodiment of the present utility model is elaborated.

Telescopic corrugated flexible hose shown in Fig. 1 and Fig. 2 includes：Ripple type body 1, the two ends of body 1 have connecting portion 2, Body 1 is folded and drawn in during the external force that is squeezed, and when external force is stretched, body 1 extends, and body 1 can bend random angle after elongation Degree.

Embodiment 1

Body 1 shown in Fig. 3 and Fig. 4（With reference to Fig. 1）By left side wall 11, arc crest wall 12, right side wall 13 and arc trough Wall 14 is alternately connected to form continuous ripple type, left side wall 11, arc crest wall 12, right side wall 13 and arc-shaped wave valley wall 14 successively Between transition in smoothing junction, the radius of curvature R 2 of arc crest wall 12 is 1.5mm, 13 linear sections of shapes of right side wall, left side wall 11 in the arc protruded outside body, and the radius of curvature R 1 of the arc is 80mm.The line of the two-end-point of right side wall 13 and the axis of body 1 Angle α be 45 °, the angle β of continuous and the line of body axle 1 of the two-end-point of left side wall 11 is 75 °.

Embodiment 2

Body 1 shown in Fig. 4 and Fig. 5（With reference to Fig. 1）By left side wall 11, arc crest wall 12, right side wall 13 and arc trough Wall 14 is alternately connected to form continuous ripple type, left side wall 11, arc crest wall 12, right side wall 13 and arc-shaped wave valley wall 14 successively Between transition in smoothing junction, the radius of curvature R 2 of arc crest wall 12 is 3mm, and right side wall 13, should in the arc protruded outside body The radius of curvature R 3 of arc is 200mm, and in the arc protruded outside body, the radius of curvature R 1 of the arc is 100mm to left side wall 11. The line of the two-end-point of right side wall 13 is 45 ° with the angle α of the axis of body 1, the continuous and line of body axle 1 of the two-end-point of left side wall 11 Angle β is 50 °.

This utility model using the arc crest wall 12 of deep camber so as to left side wall 11 be folded to right side wall 13 or away from Right side wall 13, and then realize that the folding of pipe corrugated flexible hose is drawn in or extended；The style-ability of corrugated flexible hose when improve elongation； It is that die sinking cost is substantially reduced this utility model is made, saves cost, improves yield rate.

Above-mentioned example is only intended to illustrate this utility model that embodiment of the present utility model is not limited to these examples, What those skilled in the art were made meets the various specific embodiments of this utility model thought all in guarantor of the present utility model Within the scope of shield.
