Embodiment
Below in conjunction with embodiment and accompanying drawing, the present invention is described in further detail, but embodiments of the present invention are not limited thereto.
Embodiment 1
Refer to Fig. 1-3, the thermal shrinkable sleeve 100 shown in present pre-ferred embodiments, comprise sleeve body 10 and be fixed on the movable part 20 on described sleeve body 10 sidewall.
Described sleeve body 10 obtains for material contracting with heat, and the side of the contiguous described bend pipe 1 of described sleeve body 10 is provided with the first enhancing fiberglass layer 16 and the first heat-fusing glue layer 15 successively.The sidewall of described sleeve body 10 offers a matching hole 11, described matching hole 11 is corresponding with the inner side of bend pipe 1.In the present embodiment, described matching hole 11 can be square or circular.
In one end of described movable part 20 and described sleeve body 10, the position of contiguous described matching hole 11 is fixedly connected, and the matching form of the shape of described movable part 20 and described matching hole 11 closes, and can be covered in outside described matching hole 11.In the present embodiment, the shape of described movable part 20 is consistent with the shape of described matching hole 11.Described movable part 20 comprises the overlay segment 21 be covered on described matching hole 11 and the lap segment 22 being fixed in described overlay segment 21 surrounding, described lap segment 22 contacts with the sleeve body 10 around described matching hole 11, and described lap segment 22 is fixedly connected by fixed plate (not shown) and contiguous sleeve body 10.Described movable part 20 comprises the second heat-fusing glue layer 23, shrink wrap layer 24 and is located at second between described second heat-fusing glue layer 23 and described shrink wrap layer 24 and strengthens fiberglass layer 26, the contiguous described sleeve body 10 of described second heat-fusing glue layer 23 is arranged, and described second strengthens fiberglass layer 26 can bear larger external force for making described thermal shrinkable sleeve 100.
Consider the matching hole 11 that described sleeve body 10 is offered take up space larger, for ease of the discharge of the air in this space, ensure the sealing effect of thermal shrinkable sleeve 100, described sleeve body 10 also offers some exhaust ports 12, one end of described exhaust port 12 is connected with described matching hole 11, and the other end extends to one end end face of the contiguous described movable part 20 of described sleeve body 10.The side inwall of the contiguous described movable part 20 of described exhaust port 12 is provided with the 3rd heat-fusing glue layer 13, described 3rd heat-fusing glue layer 13 is circular arc away from the side of described movable part 20, makes described 3rd heat-fusing glue layer 13 more easily can fill up described exhaust port 13 when melted by heat.In the process of this thermal shrinkable sleeve 100 of heating, gas in described matching hole 11 can be discharged by this exhaust port 12, and the 3rd heat-fusing glue layer 13 can fill up described exhaust port 13 rapidly after melted by heat, so, can large quantity of air be discharged, the airtight quality of this thermal shrinkable sleeve 100 can be ensured again.
To sum up, described sleeve body 10, when sealed elbow 1, is placed on bend pipe 1 place by thermal shrinkable sleeve 100 of the present invention, and now, described movable part 20 is open mode relative to described sleeve body 10, by corresponding with the inner side of bend pipe 1 for described matching hole 11.Described movable part 20 is covered described matching hole 11 completely, and with fixed plate, described movable part 20 is fixed, because this movable part 20 is sheet structure, can well be coated on outside bend pipe 1, so, just can effectively avoid common commercially available heat-shrink tube owing to being easy to the phenomenon generation producing fold inside bend pipe 1 and then affect pipe bent position airtight quality.Utilize again the special construction of this exhaust port 12, be convenient to discharge air, ensure sealing corrosion effect.
As mentioned above, the present invention can be realized preferably.
The above; it is only preferred embodiment of the present invention; not any pro forma restriction is done to the present invention; according to technical spirit of the present invention; within the spirit and principles in the present invention; the any simple amendment that above embodiment is done, equivalently replace and improve, within the protection domain all still belonging to technical solution of the present invention.
