Abstract
The utility model discloses a heat-shrinkable sleeve pipe. The inner wall of the heat-shrinkable sleeve pipe is provided with at least one inner convex part protruding in an extrusion direction; the inner convex part is prismatic, and the cross section of the inner convex part is in a semi-circle shape or a semi-ellipse shape; and the heat-shrinkable sleeve pipe can be prepared from rubber, plastic, or a mixed material of rubber and plastic. When the heat-shrinkable sleeve pipe is positioned in an object to be protected, the inner convex part of the heat-shrinkable sleeve pipe props against the object to be protect to ensure that an airflow channel is reserved between the inner wall of the heat-shrinkable sleeve pipe and the object to be protected; the airflow channel can enable the heat-shrinkable sleeve pipe to exhaust air therein in time during shrinking due to heating so as to ensure that the inner wall of the heat-shrinkable sleeve pipe and the object to be protected can be bonded together, so that the suffocation phenomena of the heat-shrinkable sleeve pipe during shrinking due to heating can be avoided, thereby improving the shrinking efficiency and shrinking effect of the heat-shrinkable sleeve pipe.
Description
Technical field
The utility model relates to a kind of sleeve pipe, relates in particular to a kind of heat-shrinkable T bush.
Background technique
Heat-shrinkable T bush is widely used in the insulation protection of wire harness, solder joint, inductance, antirust, the corrosion protection of metal tube, rod etc.Heat-shrinkable T bush need overlap in use to object to be protected, and then heating is heat-shrinkable to above the object to be protected it to heat-shrinkable T bush.
Yet, when being heated, heat-shrinkable T bush can at this moment just can produce the phenomenon of feeling suffocated because the inequality of being heated causes the air between heat-shrinkable T bush and the object to be protected in time not discharged, reduced contraction efficient and the contractive effect of heat-shrinkable T bush.
The model utility content
Thereby being to provide a kind of, the purpose of this utility model can avoid that producing feels suffocated improves the heat-shrinkable T bush that it shrinks efficient and contractive effect when being heated.
For achieving the above object, the utility model provides a kind of heat-shrinkable T bush, and the internal face of described heat-shrinkable T bush has at least one edge and extrudes the interior protuberance that direction protrudes out.
Preferably, described interior protuberance is the rib shape, the cross section is semicircle shape or the cross section is the semiellipse shape.
Described heat-shrinkable T bush can be made by rubber, plastics or rubber-plastics material.
Preferably, the outer wall of heat-shrinkable T bush has at least one edge and extrudes the male part that direction outwards protrudes out.
As mentioned above; the internal face of the utility model heat-shrinkable T bush has at least one edge and extrudes the interior protuberance that direction protrudes out; when the thermal shrinkable sleeve pipe box when the object to be protected; the interior protuberance of heat-shrinkable T bush and object butt to be protected guarantee to have air-flow path between the inwall of heat-shrinkable T bush and the object to be protected; air-flow path can make heat-shrinkable T bush when being subjected to thermal shrinkage, the air in it in time discharged until heat-shrinkable T bush inwall and adhering object to be protected together; produce the phenomenon of feeling suffocated when this can be avoided heat-shrinkable T bush to be subjected to thermal shrinkage, thereby improve contraction efficient and the contractive effect of heat-shrinkable T bush.

Embodiment
By describing technology contents of the present utility model, structure characteristics in detail, realized purpose and effect, below in conjunction with mode of execution and cooperate that accompanying drawing is detailed to give explanation.
See also Fig. 1, it has disclosed the first embodiment of the utility model heat-shrinkable T bush 10, and the internal face of heat-shrinkable T bush 10 has some edges and extrudes the interior protuberance 12 that direction protrudes out.
Heat-shrinkable T bush 10 comprises sleeve body 11 and some interior protuberances 12.The outer wall that interior protuberance 12 is sleeve body 11 protrudes out formation along extruding direction, should be the rib shape by interior protuberance 12 in the present embodiment.
Heat-shrinkable T bush 10 can be made by rubber, or is made of plastics, or is made by the blending material of rubber and plastics, can also for the alloy of radiation-cross-linkable polyolefin and polymer thereof as the basal heat compression material.The blending material of rubber and plastics is defined as rubber-plastics material.Certainly, the manufactured materials of heat-shrinkable T bush 10 is not limited in this.
See also Fig. 2, Fig. 2 has disclosed a kind of extruder head 20 that uses when the utility model heat-shrinkable T bush 10 is produced, because the extruder head of heat-shrinkable T bush has been prior art, therefore, only introduce the part relevant with the utility model heat-shrinkable T bush 10, this extruder head 20 comprises mouthful mould 21 and core 22.Mouth mould 21 has mouthful nib 211.The outer wall of core 22 is provided with some grooves 221, and groove 221 is rib groove shape in the present embodiment.Core 22 is arranged in mouthful mould 21 and with mouth mould 21 and is formed with forming cavity 212.Core 22 is provided with airflow hole 221.
When extrusion, because core 22 has groove 221, heat-shrinkable T bush 10 can directly be extruded is formed with interior protuberance 12.
Heat-shrinkable T bush is to utilize " shape-memory " pyrocondensation principle, extrude flexible heat shrinkable sleeve (comprising in mono-layer tube, the pipe bimetallic tube with hot melt adhesive) with material contracting with heat (for example alloy of radiation-cross-linkable polyolefin and polymer thereof), form after, the expansion crosslinked through Co-60 γ-ray or high-energy electron beam irradiation.Be enclosed within on roller, rod, the handle class article and then heat with instruments such as heat gun or bluster rifles, the reduced that makes heat-shrinkable T bush utilizes the powerful contractile force of heat-shrinkable T bush then can bind round tightly on the surface of article such as being attached to roller, rod, handle class, electric wire interface to original 25～50%.
See also Fig. 3 and Fig. 4, it has disclosed the second embodiment of the utility model heat-shrinkable T bush 10 ', present embodiment and the first embodiment are similar, its difference is: the cross section of the interior protuberance 12 ' of heat-shrinkable T bush 10 ' is semicircle shape, the groove 221 ' of a kind of extruder head 20 ' that uses when accordingly, heat-shrinkable T bush 10 ' is produced is the half slot shape.
