Abstract
The utility model discloses a be used for unsmooth fashioned heat shrinkage bush of dock pyrocondensation substrate, current heat shrinkage bush adopt the stylolite to sew up, the very inconvenient problem of operation. The utility model discloses a form circle pipy tubulose body (1) by the butt joint of pyrocondensation substrate, its characterized in that: one side of tubulose body (1) butt joint position department is provided with concave (2), the opposite side correspond position department then be provided with with concave (2) shape assorted male member (3), the pyrocondensation substrate is by constituting from interior hot -melt adhesive layer, polyolefin lining, fortifying fibre screen cloth layer and polyolefin superficial layer to setting up in order outward, the butt joint position department of tubulose body (1) both sides all is provided with one deck heat seal layer (4). The utility model has the advantages of sealed effect is showing, easy and simple to handle.
Description
Technical field
The utility model relates to a kind of heat-shrinkable T bush, and what be specifically related to is heat-shrinkable T bush for concave-convex-piece dock pyrocondensation substrate forming.
Background technique
Heat-shrinkable T bush is a kind of special polyolefin material thermal contraction casing tube, also has and is called EVA material, have the performances such as insulation, heatproof.It has soft flexible, is widely used in the insulation protection of various wire harness, solder joint, inductance, antirust, the corrosion protection of metal tube, rod.As the sealing for pipeline junctions such as petroleum pipeline, natural gas line and drainage pipes, anti-fluid is revealed from pipeline junction, causes the pollution to surrounding environment.Be used in wire terminal, can make it to tighten by heating, play insulation, the functions such as protection.Heat-shrinkable T bush is a kind of heat-shrinkage material; namely heat shrinks, and divides pvc heat-shrinkable T bush, pet heat-shrinkable T bush, IXPE heat-shrinkable T bush, 10KV high-voltage busbar can be divided into protect heat-shrinkable T bush, 35KV high-voltage busbar protection heat-shrinkable T bush, containing glue double wall heat Heat-Shrinkable Tubings and imitative wood grain heat-shrinkable T bush by material.
Heat-shrinkable T bush is overlapped by material contracting with heat to form, and material contracting with heat exists three-decker usually, two-layer material contracting with heat layer and one deck thermal synthesis layer.Easily shrink because material contracting with heat is heated when 2-4mm is thick, can tightly be attached on pipeline, thus in the using process of reality, after only heat-shrinkable T bush need being socketed in pipeline junction, heating makes heat-shrinkable T bush shrink being attached on pipeline tightly.But because heat-shrinkable T bush is all adopt stitching thread to sew up, it is very inconvenient to operate, and the area of contact of joint is too small, and the situation of cracking occurs easily to cause suture location place to occur, and then affects sealability.
Model utility content
The purpose of this utility model is that solving existing heat-shrinkable T bush is all adopt stitching thread to sew up, and operates very inconvenient problem, provides a kind of significant sealing affection and the heat-shrinkable T bush for concave-convex-piece dock pyrocondensation substrate forming easy and simple to handle.
For achieving the above object, the technical solution of the utility model is as follows:
For the heat-shrinkable T bush of concave-convex-piece dock pyrocondensation substrate forming, comprise and dock by pyrocondensation base material the tubular body forming circular tube shaped, the side at tubular body docking location place is provided with female members, and opposite side corresponding position is then provided with the male member with female members mating shapes; Described pyrocondensation base material is made up of the heat-fusing glue layer arranged in turn from the inside to the outside, polyolefin lining, reinforcing fiber scrim layer and polyolefin surfaces layer; The docking location place of described tubular body both sides is provided with one deck thermal synthesis layer.
The utility model adopts the mating reaction of female members and male member, effectively avoids existing heat-shrinkable T bush to adopt stitching thread to carry out the process sewed up, more convenient to operate.
Simultaneously this female members and male member setting, effectively increase the area of contact of joint, and then strengthen adhesive effect, reduce docking location place and occur that the situation of cracking occurs, ensure sealability.
In order to reach best sealing effect, the situation causing sealing effect not good due to condensation when avoiding heating occurs, and described female members is preferably set to trapezoidal, and the length inside this female members is greater than outside.
Preferred as one, described thermal synthesis layer is made up of hot melt adhesive material.
Further, described female members and male member are all one-body molded with tubular body.
Further, reinforcing fiber scrim layer is the reticular structure of working out with glass fibre and polyethylene, and polyethylene is warp, and glass fibre is parallel, and the distance between adjacent warp is 0.1-5mm, and the distance between adjacent parallel is 1-10mm.
The utility model compared with prior art, has the following advantages and beneficial effect:
1, the utility model adopts the mating reaction of female members and male member, effectively avoids existing heat-shrinkable T bush to adopt stitching thread to carry out the process sewed up, more convenient to operate;
2, in the utility model this female members and male member setting, effectively increase the area of contact of joint, and then strengthen adhesive effect, reduce docking location place and occur that the situation of cracking occurs, ensure sealability;
3, simple, the Be very effective of the utility model structure, is applicable to applying very much.
