Embodiment
Below in conjunction with embodiment and accompanying drawing, the utility model is described in further detail, but mode of execution of the present utility model is not limited thereto.
Embodiment 1
Refer to Fig. 1-3, the thermal shrinkable sleeve 100 shown in the utility model preferred embodiment, 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 one first heat-fusing glue layer 15.The sidewall of described sleeve body 10 offers consistent cavity 11 and some containing grooves 13, and described through chamber 11 is corresponding with the inner side of bend pipe 1.In the present embodiment, described through chamber 11 can be square or circular.Arbitrary containing groove 13 comprises a diapire and opposing parallel two side, described diapire one end is crossing with the sidewall in described through chamber 11, the other end extends to the end face of contiguous described movable part 20 one end of described sleeve body 10, so, arbitrary containing groove 13 is connected with described through chamber 11, is convenient to coordinate described movable part 20.The diapire of described containing groove 13 is a cambered surface.
Described movable part 20 is sheet structure, comprises the second heat-fusing glue layer 23 and shrink wrap layer 24, and the contiguous described sleeve body 10 of described second heat-fusing glue layer 23 is arranged.In one end of described movable part 20 and described sleeve body 10, the position in contiguous described through chamber 11 is fixedly connected, and the matching form in the shape of described movable part 20 and described through chamber 11 closes, and can be covered in outside described through chamber 11.In the present embodiment, the shape of described movable part 20 is consistent with the shape in described through chamber 11.Described movable part 20 comprises the overlay segment 21 be covered on described through chamber 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 through chamber 11, and described lap segment 22 is fixedly connected by fixed plate (not shown) and contiguous sleeve body 10.The side of the contiguous described sleeve body 10 of described lap segment 22 has protruded out and described containing groove 13 hot melt adhesive projection 25 one to one, and arbitrary hot melt adhesive projection 25 is placed in corresponding containing groove 13.The end face of arbitrary hot melt adhesive projection 25 is the flat face of an inclination, so, one is formed for the exhaust passage 12 of Exhaust Gas between the end face of this hot melt adhesive projection 25 and the diapire of corresponding containing groove 13, be convenient to the discharge of the air in through chamber 11, ensure the sealing effect of thermal shrinkable sleeve 100, and the hot melt adhesive projection 25 of this side, exhaust passage 12 can fill up described exhaust passage 12 rapidly after melted by heat, so, can large quantity of air be discharged, the sealing corrosion effect of this thermal shrinkable sleeve 100 can be ensured again.
