Abstract

The invention relates to a plastic tube bundle, which comprises an annular loop and an internal clamping component. The clamping component consists of two interlocked parts, wherein each interlocked part comprises a section of ratchet bar; the directions of the two sections of ratchet bars are opposite; two sections of protruding rings are parallel to the two ratchet bars respectively, a certain distance is kept between the two sections of protruding rings and the two ratchet bars, and the opposite ratchet bars can extend into the clearance thus produced; the ratchet bars are interlocked through a set of triangular tapped teeth; and the tooth tops on one section of ratchet bar are concentrated in the center of an external top end, and the tooth tops of the other section of ratchet bar are concentrated in the center of an internal top end.

Description

A kind of plastic tube bundle

Technical field

The present invention relates to a kind of tube bank, be made of plastics fully, more specifically, relate to the anchor clamps that use for flexible pipe.

Background technique

At present, the integral type plastic tube bundle generally all uses interlocking tooth bar and bulge loop.Its shortcoming is, for failure and other reasons, these tube bank meetings are because tilting action and breaking away from from flexible pipe in the unsuitable time, and this moment, the circumferential band part was twisted into helical, and tube bank is unclamped and can not be played fastening effect.

Summary of the invention

The objective of the invention is to overcome above-mentioned shortcoming, a kind of tube bank conveniently and solidly is provided.

A kind of plastic flexible pipe bundle, form by open-ended annular pipe collar and clamp assembly, above-mentioned group. part has been formed first and second interlocking members, and these parts comprise one section ratchet bar respectively, and two ratchet bars are reverse mutually, two bulge loops are parallel with two ratchet bars respectively, corresponding between two ratchet bars have a hole, and reverse ratchet bar can stretch into wherein, and above-mentioned ratchet bar is by the interlocking of pyrometric cone tooth, tooth top on one section ratchet bar converges at the outer tip end mid point, and the tooth top of another section ratchet bar converges at the inner tip mid point.

Above-mentioned interlocking pyrometric cone toothing can prevent that circumferential band from being twisted into helical; Circumferential band is fastened to device on the flexible pipe, because the taper configurations of circumferential band internal surface, is applied to additional pressure on the outer tangent line of flexible pipe greater than the lip-deep additional pressure of broad.

Foregoing has embodied advantage of the present invention and innovation.The present invention in many ways, method, structure, parts combination meter revealed the novel and unique of design.

Description of drawings

Accompanying drawing is a schematic representation of the present invention, wherein:

Fig. 1 is a schematic perspective view of the present invention;

Fig. 2 is the sectional view of Fig. 1 section line 2-2;

Fig. 3 is a front view of the present invention.

Embodiment

In order more specifically to set forth structure of the present invention and meaning, be described further below in conjunction with accompanying drawing:

Foregoing invention is a plastic tube bundle 10, combine by open-ended annular pipe collar 12 and clamp assembly 14, said modules has been formed first and second interlocking

members

16 and 18, these parts comprise

ratchet bar

20 and 22 respectively, two ratchet bars are reverse mutually, bulge loop 24 is parallel with ratchet bar respectively with 26, and certain spacing is arranged, produce

hole

28 and 30 thus, reverse ratchet bar can stretch into wherein, and above-mentioned ratchet bar is by

pyrometric cone tooth

32 and 34 interlockings, shown in sectional view, the tip edge of ratchet bar 22 38 converges towards outer tip end center 40 from the outer end, and the summit seamed edge 42 of ratchet bar 20 converges at inner tip center 44.

Interlocking

member

16 and 18 opposite end at pipe collar 12, and in the plane of rotation of pipe collar, cancel each other, its optimal view is as shown in Figure 3.Wherein parts 18 are more protruding a little than parts 16.

Parts

16 and 18 comprise

accessory

46 and 48 respectively, and ratchet bar 20 and bulge loop 24 are fixed on the parts 46, and ratchet bar 22 and bulge loop 26 are fixed on the parts 48 simultaneously.Towards surface 50 indentations in the pipe collar outside, when tube bank is in firm locked position shown in Figure 1 and a certain when uncaging between fixed position or the unlocked position shown in Figure 3, can make that to tighten operation convenient on the accessory.

When the clamp assembly interlocking, the most inboard bulge loop 24 and outermost bulge loop 26 are in the opposite direction.Bulge loop 24 and ratchet bar 20 form hole 28, and bulge loop 26 and ratchet bar 22 form hole 30.Hole is made up of adjacent ratchet bar and bulge loop, is used to place another section ratchet bar.

When pipe collar 12 was fastened on the flexible pipe, vertical center line 52 diameters of pipe collar internal surface 54 were less than outer rim in parallel 58.So see on cross section, above-mentioned internal surface shows light shade, and above center line 52 is projected in.When device was fastening as Fig. 1, flexible pipe was promptly firmly pinned.

When tube bank snaps into when the tightest, perhaps in order to prevent tension,

bulge loop

24 and 26 end 60 will be respectively near salient angles 62 and 64.The present invention can be applicable to the flexible pipe of various diameters, and when this tube bank was secured to the limit, the end of bulge loop can withstand above-mentioned salient angle.The situation bigger may occur restraining, thereby tube bank needs various size than flexible pipe.

Awl tooth

32 and 34 is ratchets, when its in plane of rotation of tube bank during interlocking, can be because of the return motion release.Unless deflection of having a mind to or broken ring, otherwise the tube bank that is fastened on the flexible pipe can not break away from.The release behavior of having a mind to is meant between 2

cover ratchets

32 and 34 carries out deflection or lateral deflection by force.This can become helical from annular with the shape of pipe collar 12.Ratchet 32 and 34 blocks mutually, makes tube bank locking.

Claims

1. plastic tube bundle, form by open-ended annular pipe collar and clamp assembly, it is characterized in that: said modules has been formed first and second interlocking members, these parts comprise one section ratchet bar respectively, two ratchet bars are reverse mutually, two bulge loops are parallel with two ratchet bars respectively, and certain spacing is arranged, produce corresponding hole thus, reverse ratchet bar can stretch into wherein, above-mentioned ratchet bar is by the interlocking of pyrometric cone tooth, and the tooth top on one section ratchet bar converges at the outer tip end mid point, and the tooth top of another section ratchet bar converges at the inner tip mid point.

2. plastic tube bundle as claimed in claim 1 is characterized in that: when the aforementioned tube banding was affixed on the flexible pipe, pipe collar internal surface longitudinal center linear diameter was less than outer rim in parallel.

3. plastic tube bundle as claimed in claim 1 is characterized in that: the taper configurations of circumferential band internal surface.
