Summary of the invention

The purpose of this utility model is to there are the problems referred to above for existing technology, it is proposed that A kind of compound pipeline complex pipeline strengthens joint, and this compound pipeline complex pipeline strengthens joint and has compound pipeline complex pipeline slow Shake effect, and stability in use is high.

The purpose of this utility model can be realized by following technical proposal: a kind of multiple tube Road strengthens joint, it is characterised in that include tubular body and metallic sheath, described On the periphery wall of body, circumference offers locating slot, and described metallic sheath fixed cover is located at locating slot In, and metallic sheath medial surface fits with locating slot bottom surface and compresses, the phase of described locating slot Circumference equal on two cell walls is offered cannelure, and the edge, two ends of described metallic sheath is stretched respectively Entering in cannelure, described body uses elastomeric material to make.

It is internal that this is inserted by the two ends of body respectively in the end of two compound pipeline complex pipelines needing docking Kong Zhong, metallic sheath clamping sleeve is located in the locating slot of body, it is possible to held tightly by body, i.e. Can be to two compound pipeline complex pipeline metal restriction location, compound pipeline complex pipeline is risen by the body of quality of rubber materials To bradyseism effect, improving compound pipeline complex pipeline service life, further, locating slot is to metal Set plays location, and metallic sheath has bigger width, and two annulars are inserted at its two ends respectively In groove, increase the constraint area to body, also be able to eliminate locating slot bottom surface and groove simultaneously The stress that corner between wall produces is concentrated, it is to avoid body in locating slot bottom surface and cell wall it Between corner occur fracture, improve stability in use.

In above-mentioned compound pipeline complex pipeline strengthens joint, a cell wall of described cannelure and location Groove bottom flushes, the two ends of described metallic sheath respectively with two cannelure tight fits.I.e. avoid There is fracture in body, increases the connective stability between metallic sheath and body simultaneously, increases The metallic sheath constraint stationkeeping ability to body.

In above-mentioned compound pipeline complex pipeline strengthens joint, it is some fixed that described metallic sheath offers Hole, position, the bottom surface of described locating slot is evenly equipped with some positioning convex, described positioning convex Grafting is positioned in hole, location.Positioning convex with location hole match, increase metallic sheath with Bed knife between body, it is to avoid metallic sheath occurs that the rotation of circumference channels bit.

In above-mentioned compound pipeline complex pipeline strengthens joint, described body is positioned at locating slot both ends The external diameter divided is tapered into outward by the inner.The i.e. elasticity at body two ends is relatively big, convenient The insertion of compound pipeline complex pipeline.

In above-mentioned compound pipeline complex pipeline strengthens joint, it is axial that described locating slot is positioned at body Middle part, and body is positioned at the width of the locating slot two end portions width less than locating slot.This The two ends of body are symmetrical arranged so that two compound pipeline complex pipelines are produced active force symmetrically, Improve the connective stability of compound pipeline complex pipeline.

In above-mentioned compound pipeline complex pipeline strengthens joint, the two ends outer edge circumference of described body There is arc angling.When compound pipeline complex pipeline inserts body endoporus, the arc at body edge falls Stability, it can be avoided that tear or crack occurs in body, is improved in angle.

Compared with prior art, this compound pipeline complex pipeline enhancing joint has the advantage that

1, inserted in body endoporus by the two ends of body respectively due to the end of compound pipeline complex pipeline, Metallic sheath clamping sleeve is located in the locating slot of body, it is possible to held tightly by body, i.e. can be right Two compound pipeline complex pipeline metal restriction location, compound pipeline complex pipeline is played bradyseism by the body of quality of rubber materials Effect, improves compound pipeline complex pipeline service life.

2, having bigger width due to metallic sheath, its two ends are inserted in two cannelures respectively, Increase the constraint area to body, also be able to eliminate between locating slot bottom surface and cell wall simultaneously Corner produce stress concentrate, it is to avoid body limit between locating slot bottom surface and cell wall There is fracture in angle, improves stability in use.

3, it is symmetrical arranged owing to locating slot is positioned at the two ends at the middle part that body is axial, i.e. body, Make two compound pipeline complex pipelines are produced active force symmetrically, improve the connection of compound pipeline complex pipeline Stability.

Detailed description of the invention

The following is specific embodiment of the utility model and combine accompanying drawing, to this utility model Technical scheme be further described, but this utility model is not limited to these embodiments.

As shown in Figure 1 and Figure 2, a kind of compound pipeline complex pipeline strengthens joint, including tubular Body 1 and metallic sheath 2, on the periphery wall of body 1, circumference offers locating slot 11, gold Belong to set 2 fixed covers to be located in locating slot 11, and metallic sheath 2 medial surface and locating slot 11 Bottom surface fits and compresses, and on relative two cell walls of locating slot 11, equal circumference offers cannelure 12, the edge, two ends of metallic sheath 2 is respectively protruding in cannelure 12, and body 1 uses rubber Material is made.The end of two compound pipeline complex pipelines needing docking is inserted by the two ends of body 1 respectively Entering in body 1 endoporus, metallic sheath 2 clamping sleeve is located in the locating slot 11 of body 1, energy Enough body 1 is held tightly, i.e. can be to two compound pipeline complex pipeline metal restrictions location, quality of rubber materials Body 1 compound pipeline complex pipeline is played bradyseism effect, improve compound pipeline complex pipeline service life, enter One step, metallic sheath 2 is played location by locating slot 11, and metallic sheath 2 has bigger Width, its two ends are inserted in two cannelures 12 respectively, increase the constraint area to body 1, It also is able to eliminate the stress collection of the corner generation between locating slot 11 bottom surface and cell wall simultaneously In, it is to avoid there is fracture in the body 1 corner between locating slot 11 bottom surface and cell wall, carries High stability in use.

Specifically, a cell wall of cannelure 12 flushes with locating slot 11 bottom surface, metal Set 2 two ends respectively with two cannelure 12 tight fits, i.e. avoid body 1 occur fracture, Increase the connective stability between metallic sheath 2 and body 1 simultaneously, increase metallic sheath 2 right The constraint stationkeeping ability of body 1.Hole, some location 21 is offered, location on metallic sheath 2 Being evenly equipped with some positioning convex 13 on the bottom surface of groove 11, positioning convex 13 grafting is positioned at In hole 21, location, positioning convex 13 matches with hole 21, location, increases metallic sheath 2 And the bed knife between body 1, it is to avoid metallic sheath 2 occurs that the rotation of circumference channels bit.This Body 1 is positioned at the external diameter of locating slot 11 two end portions and is tapered into outward by the inner, i.e. originally The elasticity at body 1 two ends is relatively big, facilitates the insertion of compound pipeline complex pipeline.Locating slot 11 is positioned at body 1 axial middle part, and body 1 is positioned at the width of locating slot 11 two end portions less than location The width of groove 11, the two ends of body 1 are symmetrical arranged so that produce two compound pipeline complex pipelines all The active force of even symmetry, improves the connective stability of compound pipeline complex pipeline.Outside the two ends of body 1 Edge circumference has arc angling, when compound pipeline complex pipeline inserts body 1 endoporus, and body 1 The arc angling at edge, it can be avoided that tear or crack occurs in body 1, improves stability.
