Description
Technical field
The utility model relates to a kind of heat-shrinkable T bush, and what be specifically related to is the docking style heat-shrinkable T bush containing opening cell body.
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 heated the characteristic of easily shrinking, contraction due to outside heat-shrinkable T bush and inner side during heating is inconsistent, when making operation, easily there is error, and then the situation causing joint poorly sealed, pipeline is easy to corrode herein, fluid in pipeline is also easily revealed from here, causes the pollution of surrounding environment.
Model utility content
When the purpose of this utility model is to solve heating outside existing heat-shrinkable T bush and the contraction of inner side inconsistent, and then the situation causing joint poorly sealed, provides a kind of docking style heat-shrinkable T bush containing opening cell body of easy and simple to handle, Be very effective.
For achieving the above object, the technical solution of the utility model is as follows:
Containing the docking style heat-shrinkable T bush of opening cell body, comprise and dock by pyrocondensation base material the tubular body forming circular tube shaped, tubular body docking location place is provided with connection strap, and connection strap is fixed together by stitching thread and tubular body; The outer side wall of described tubular body is provided with opening cell body along axis, and the degree of depth of described opening cell body is 1/3 ~ 1/2 of tubular body thickness, and the width of opening cell body is less than 1/20 of tubular body girth.
By the setting of opening cell body, avoid the inner side and outer side caused during the pyrocondensation base material heating of tubular body to shrink inconsistent, and then affect installation precision, cause the situation that joint is poorly sealed.By above-mentioned setting, effectively reach while ensureing usability, convenient installation, improves installation precision.
As the setting of optimum, described opening cell body is three, is evenly distributed on the outer side wall of tubular body.By the selection of three opening cell bodies, the Performance Strength of opening cell body to tubular body effectively can be avoided to impact, effectively ensure the working life of tubular body.
Further, described sutural wire diameter is 0.1 ~ 0.8mm, and sutural stitch distance is 1 ~ 10mm.
Further again, described stitching thread is selected from cotton, polyolefin, nylon, terylene, polyamide fibre, polyvinyl, aramid fiber.
Further, also thermal synthesis layer is provided with between described lap segment.
Preferably, described connection strap comprises the matrix that the left and right sides all has thermal synthesis layer, and is arranged on the emulsion sheet of matrix top side, and the height of this matrix is identical with tubular body thickness.By the setting of this structure, while effectively ensureing sealability, ensure the aesthetics of outward appearance.
More preferably, described emulsion sheet bottom surface is also provided with thermal synthesis layer.By this setting, improve sealability further.
The utility model compared with prior art, has the following advantages and beneficial effect:
1, the utility model is by the setting of opening cell body, avoids the inner side and outer side caused during the pyrocondensation base material heating of tubular body to shrink inconsistent, and then affects installation precision, cause the situation that joint is poorly sealed.By above-mentioned setting, effectively reach while ensureing usability, convenient installation, improves installation precision;
2, the utility model is by the selection of three opening cell bodies, can effectively avoid the Performance Strength of opening cell body to tubular body to impact, and effectively ensures the working life of tubular body;
3, simple, the Be very effective of the utility model structure, is applicable to applying very much.
