Abstract
The utility model provides an overlapping rib structure used for a thermal shrinkable casing pipe. In the utility model, heat-shrinkable sheet material is utilized to be coiled and wrapped on a cylindrical filler strip with thermal stability, and after molding processing, the R-shaped rib is formed. When the thermal shrinkable casing pipe with the structure is adopted, a C-shaped metal clamping strip of the heat shrinkable casing pipe can be directly heated and can not slide out, and the sealing effect is favorable.
Description
The present invention relates to a kind of structure that heat-shrinking plastics sheet material longitudinal edge is shaped to " R " shape muscle.Utilize this structure that sheet material is made longitudinally packed type heat shrinkable sleeve, the sealing that its muscle portion can directly heat and tool is good.
The heat-shrinkable T bush that is used for communication cable joint is divided into vertical packet mode and circular pipe type.Common longitudinally packed type heat shrinkable sleeve is that thermal contraction sheet material two edges have " R " shape muscle 1 as shown in Figure 1, with " C type " metal card article 2 its pinning is just become tubular structure, is coated on heat shrink on the cable joint.Moulding when " R " shape muscle of this kind heat-shrinkable T bush is the plastic sheet extrusion molding is heated directly during construction that it can soften, and easily skidded off under " C " shape card article by the convergent force effect, so it can not directly heat.This just makes the PUR fusion that is coated with in this position insufficient, and the sealing at this place was easily lost efficacy.
The present invention proposes a kind of new " R " shape muscle structure, it has overcome the above-mentioned shortcoming of common " R " shape muscle, adopts the longitudinally packed type heat shrinkable sleeve sealing of this structure firm, is particularly suitable for the sealing of Inflate cable joint.
What the present invention adopted is following structure:
Fig. 2 is the thermal contraction sheet material, as common polyethylene pyrocondensation sheet material or strong fiber pyrocondensation sheet material, is coated with one deck hotmelt on the sheet material.
Fig. 3 is this " R " shape muscle structure after the moulding.It is to be surrounded on the cylindric filler bar 4 of a thermal stability by pyrocondensation sheet material 3 turnups, and through certain moulding process, makes it " R " type.
The available various engineering plastics of filler bar as nylon, polyester, Merlon, ABS etc. or metal material, are made as aluminium, copper, iron etc.
Fig. 4 becomes tubular structure after pinning at " C " shape metal card article.
When " R " of the present invention shape muscle structure was the heat-shrinkable T bush heat shrink, muscle portion directly was heated, and shrank thickening muscle thickening and swelled, with the inner turgor of " C " shape metal card article and self-locking, can under card article, not skid off, and form sealing behind the turgor, herein can air leakage failure.
Claims (2)
1, the overlap joint muscle is assured in a kind of novel thermal contraction, it is characterized by the sheet material turnup is paperwrapped on the filler bar to form " R " shape muscle bridging arrangement after moulding.
2, according to claim 1, the overlap joint muscle is assured in described thermal contraction, it is characterized by, and the filler bar that is somebody's turn to do " R " shape muscle is the cylindric material of thermal stability, and its material is nylon, fine aluminium, polyethylene.
