Description

Technical Field

[0001] The utility model relates to the technical field of heat shrinkable sleeves, and in particular to an anti-UV self-exhausting heat shrinkable sleeve. Background Art

[0002] Heat shrink tubing is a specialized polyolefin tubing made with a high-quality, soft, cross-linked polyolefin outer layer and an inner layer of a low-melting-point, waterproof, and highly adhesive hot-melt adhesive. This material offers excellent insulation, corrosion protection, and abrasion resistance, making it suitable for insulating wires, cables, and wire terminals, as well as protecting metal pipes and rods from rust and corrosion. Heat shrink tubing shrinks upon application of heat, tightly wrapping around wires, cables, or metal surfaces to form a protective layer. This layer not only provides insulation and corrosion protection but also rapidly shrinks upon heating, conforming closely to the object being protected, enhancing its effectiveness.

[0003] Before shrinking, there is a large gap between the heat shrink tubing and the protected pipe. After shrinking, the volume of the heat shrink tubing will decrease rapidly, causing the gas that cannot be discharged to accumulate in the middle, and then form bubbles. The bubbles will affect the use effect of the heat shrink tubing. Utility Model Content

[0017] Compared with the prior art, the beneficial effects of the present invention are:

[0018] The utility model adopts the design of the exhaust groove, which can guide the gas remaining in the heat shrinkable sleeve body into the inner cavity of the inner cylinder during the shrinkage of the heat shrinkable sleeve body. The gas then passes through the through hole into the annular cavity, and is then discharged through the hollow attachment cover and the exhaust bin, thereby avoiding the problem of bubbles being easily formed in the heat shrinkable sleeve body during the shrinkage process, thereby ensuring the use effect of the heat shrinkable sleeve body.

[0025] As Figures 1-4 shown, the utility model provides a technical scheme: an anti-UV type self-exhaust heat shrinkable sleeve, including anti-UV type heat shrinkable sleeve 1, the middle part of anti-UV type heat shrinkable sleeve 1 is provided with middle exhaust mechanism 2, anti-UV type heat shrinkable sleeve 1 includes heat shrinkable sleeve main body 11, the inner wall of heat shrinkable sleeve main body 11 close to middle exhaust mechanism 2 is provided with exhaust groove 12, the outer wall of anti-UV type heat shrinkable sleeve 1 is coated with dark color coating 13, the outer wall of dark color coating 13 is coated with sunscreen coating 14, the inside of sunscreen coating 14 contains nano particles, the nano particles can reflect most of the infrared rays and ultraviolet rays in sunlight back, thereby reducing the direct irradiation of ultraviolet rays on heat shrinkable sleeve main body 11, the color of dark color coating 13 is dark, can absorb the ultraviolet rays passing through sunscreen coating 14, further prolongs the service life of heat shrinkable sleeve main body 11 when being exposed to outdoor, through the design of exhaust groove 12, can guide the gas remaining in the inside of heat shrinkable sleeve main body 11 into middle exhaust mechanism 2 in the process of heat shrinkable sleeve main body 11 shrinkage, then passes through middle exhaust mechanism 2 and is discharged, realizes the function of self-exhaust, and when heat shrinkable sleeve main body 11 continues to shrink, heat shrinkable sleeve main body 11 can produce deformation and extrude and fill exhaust groove 12, promote exhaust groove 12 to disappear, avoid the problem that the residual exhaust groove 12 can affect the protection effect of anti-UV type heat shrinkable sleeve 1 as a whole.

[0026] As one of the embodiments in the embodiment, as Figure 3 、 Figure 4As shown, the middle exhaust mechanism 2 includes a receiving ring 21, and the number of the receiving rings 21 is set to two. The two receiving rings 21 are fixedly connected to the middle of the heat shrinkable sleeve body 11. An outer cylinder 22 is fixedly installed between the adjacent sides of the two receiving rings 21, and an inner cylinder 23 is fixedly installed between the adjacent sides of the two receiving rings 21. An annular cavity 24 is formed between the inner wall of the outer cylinder 22 and the outer wall of the inner cylinder 23. A through hole 25 is opened on the inner wall of the inner cylinder 23, and a hollow attachment cover 26 is fixedly connected to the top of the outer cylinder 22. During the shrinkage of the heat shrinkable sleeve body 11, the gas inside the exhaust groove 12 will enter the inner cavity of the inner cylinder 23, and the gas will then pass through the through hole 25 into the annular cavity 24, and then pass through the hollow attachment cover 26 and the exhaust bin 27 to be discharged.

[0027] As an implementation method in this embodiment, Figure 3 、 Figure 4 As shown, the top of the hollow attachment cover 26 is fixedly connected to the exhaust bin 27, and an inner partition 271 is fixedly installed on the inner wall of the exhaust bin 27. A circular hole is opened on the top of the inner partition 271, and an inner support frame 272 is fixedly installed on the inner wall of the circular hole. A rubber block 273 is fixedly connected to the inner wall of the circular hole. The outer wall of the rubber block 273 is movably connected to the outer wall of the inner support frame 272. A movable cover 274 is movably connected to the top of the exhaust bin 27, and a rubber sleeve 275 is fixedly connected to the outer wall of the movable cover 274. The outer wall of the rubber sleeve 275 is movably connected to the inner wall of the exhaust bin 27. A reinforcement 276 is fixedly installed on the inner wall of the movable cover 274. When the shrink sleeve body 11 shrinks to exhaust, the gas will squeeze the rubber block 273 and be discharged from the gap between the inner support frame 272 and the rubber block 273. When the exhaust stops, the rubber block 273 will produce a reset deformation to seal the gap between the inner support frame 272 and the rubber block 273, thereby realizing the function of self-sealed exhaust and preventing external impurities from easily passing through the circular hole on the exhaust bin 27 and falling into the middle exhaust mechanism 2. After the shrinkage of the heat shrink sleeve body 11 is completed, the movable cover 274 is inserted into the exhaust bin 27. Through the design of the rubber sleeve 275, the connection between the movable cover 274 and the exhaust bin 27 can be sealed.

[0028] Working principle: When in use, the protected tube is inserted into the inner cavity of the heat shrinkable sleeve body 11, and then an external hot air blower is used to deliver hot air to the surface of the UV-resistant heat shrinkable sleeve 1 to cause the heat shrinkable sleeve body 11 to shrink. During the shrinkage of the heat shrinkable sleeve body 11, the gas remaining inside the heat shrinkable sleeve body 11 will enter the inner cavity of the inner cylinder 23 through the exhaust groove 12, and the gas will then pass through the through hole 25 into the annular cavity 24, and then be discharged through the hollow attachment cover 26 and the exhaust bin 27. After the shrinkage of the heat shrinkable sleeve body 11 is completed, the movable cover 274 is inserted into the exhaust bin 27 to seal the exhaust bin 27.

[0029] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit the same.
