Abstract
The utility model discloses a pyrocondensation sealing member suitable for return bend department, include the sleeve body and be fixed in the moving part on the sleeve body lateral wall, the sleeve body makes for pyrocondensation material, a mating holes has been seted up on the lateral wall of sleeve body, the mating holes is inboard corresponding with the return bend, the moving part is the sheet structure, and looks fixed connection is located to the position of neighbouring mating holes on the one end of moving part and the sleeve body, the moving part includes hot -melt adhesive layer and pyrocondensation layer, the neighbouring sleeve body of hot -melt adhesive layer sets up, the moving part is including covering overlay and rigid coupling in the overlay overlap joint section all around on the mating holes, the overlap joint section contacts with mating holes sleeve body on every side, a stationary blade is fixed in the outside of the sleeve body of overlap joint section and vicinity, make overlap joint section and sleeve body looks fixed connection. The pyrocondensation sealing member can effectively avoid ordinary commercially available pyrocondensation pipe because the easily inboard phenomenon emergence that produces the fold and then influence the sealed antiseptic effect of return bend department of return bend.
Description
Technical field
The utility model relates to heat-shrinkable product field, particularly, relates to a kind of pyrocondensation Sealing being applicable to pipe bent position.
Background technique
Heat-shrinkable product due to have excellent flame retardant property, insulating property, very soft flexible, shrinkage temperature is low, contraction is fast and be widely used in the connection of electric wire, wire end process, solder joint protection, wire harness mark, the insulation protection of resistance capacitance, metal bar or the sealing corrosion proof protection of tubing, the protection etc. of antenna.Under high-energy ray effect, linear polymeric material forms three-dimensional netted cross-linked structure.Macromolecular material after crosslinked mechanical strength, heatproof, chemically-resistant solvent, ageing-resistant etc. in obtain and greatly improve, particularly acid-and base-resisting performance is greatly improved.
But pyrocondensation Sealing commercially available at present, be generally the cylindrical-shaped structure of hollow, be applicable to straight tube class formation, when it is for being tightly connected of pipe bent position, inside bend pipe, place is easy to fold, thus make more air hang out between pyrocondensation Sealing and tube wall and be not easy to be discharged, affect the sealing corrosion effect of this pipe bent position.
Model utility content
Technical problem to be solved in the utility model is to provide a kind of pyrocondensation Sealing being applicable to pipe bent position, ensures the sealing corrosion effect of pipe bent position.
The technical scheme in the invention for solving the above technical problem is:
A kind of pyrocondensation Sealing being applicable to pipe bent position, comprise sleeve body and be fixed on the movable part on described sleeve body sidewall, described sleeve body is that material contracting with heat obtains, the sidewall of described sleeve body offers a matching hole, described matching hole is corresponding with the inner side of bend pipe, described movable part is sheet structure, and the position of contiguous described matching hole is fixedly connected in one end of described movable part and described sleeve body, described movable part comprises heat-fusing glue layer and shrink wrap layer, the contiguous described sleeve body of described heat-fusing glue layer is arranged, described movable part comprises the overlay segment be covered on described matching hole and the lap segment being fixed in described overlay segment surrounding, described lap segment contacts with the sleeve body around described matching hole, one fixed plate is fixed on the outside of described lap segment and contiguous sleeve body, described lap segment and described sleeve body are fixedly connected.
Further, described matching hole is square or circular.
Further, the shape of described movable part is consistent with the shape of described matching hole.
To sum up, the beneficial effects of the utility model are: pyrocondensation Sealing described in the utility model can effectively avoid common commercially available heat-shrink tube owing to being easy to the phenomenon generation of the sealing corrosion effect producing fold inside bend pipe and then affect pipe bent position.
Accompanying drawing explanation
Fig. 1 is the schematic diagram of the pyrocondensation Sealing shown in the utility model preferred embodiment when being placed on pipe bent position;
Fig. 2 is the structural representation of the pyrocondensation Sealing shown in the utility model preferred embodiment;
Mark and corresponding component title in accompanying drawing: bend pipe 1, pyrocondensation Sealing 100, sleeve body 10, movable part 20, matching hole 11, overlay segment 21, lap segment 22.
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. 1-2, the pyrocondensation Sealing 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 for material contracting with heat obtain.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 heat-fusing glue layer and shrink wrap layer, and the contiguous described sleeve body 10 of described heat-fusing glue layer is arranged.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, one fixed plate (not shown) is fixed on the outside of described lap segment 22 and contiguous sleeve body 10, and described lap segment 22 is fixedly connected with described sleeve body 10.
To sum up, described sleeve body 10, when sealed elbow 1, is placed on bend pipe 1 place by pyrocondensation Sealing 100 described in the utility model, 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 of the sealing corrosion effect producing fold inside bend pipe 1 and then affect pipe bent position.
As mentioned above, the utility model can be realized preferably.
The above; it is only preferred embodiment of the present utility model; not any pro forma restriction is done to the utility model; according to technical spirit of the present utility model; within spirit of the present utility model and principle; the any simple amendment that above embodiment is done, equivalently replace and improve, within the protection domain all still belonging to technical solutions of the utility model.
