[0002] A heat shrinkable tube is a special polyolefin material heat shrinkable sleeve, whose outer layer is made of high-quality soft cross-linked polyolefin material and the inner layer is made by hot melt adhesive composite processing. This kind of pipe has a large inner diameter under normal state and can be easily sleeved on various shaped objects such as cables, wires, connectors, pipe fittings, etc. When heated by an external heat source (such as a hot air gun, hot water, electric heating, etc.), the heat shrinkable tube will shrink according to a pre-set shrinkage ratio to form a closely fitting protective layer.

[0003] After retrieval, the utility model patent with the Chinese patent publication number CN218548101U discloses a heat shrinkable tube, which includes a heat shrinkable tube body and an expansion sleeve; the heat shrinkable tube body passes through the expansion sleeve, and both sides of the heat shrinkable tube body are folded over the expansion sleeve. This utility model can facilitate the staff to pass the wire harness through the heat shrinkable tube and improve work efficiency.

[0004] After retrieval, the above patent has dealt with the convenience of using the heat shrinkable tube, but this device fails to deal with the impact resistance of the heat shrinkable tube, so that when the heat shrinkable tube is subjected to external impact or extrusion, it may be more likely to deform or break, and cannot effectively protect internal components such as wires and cables.

Specific implementation manners

[0021] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments.

[0022] Referring to Figures 1-4 , a heat - shrinkable tube with an impact - resistant structure includes a heat - shrinkable tube 1. A protective sleeve 2 is arranged outside the heat - shrinkable tube 1. Heat - shrinkable members 8 are arranged at both ends of the protective sleeve 2. The inner wall of the heat - shrinkable member 8 is in contact with the side wall of the heat - shrinkable tube 1. A plurality of elastic members 4 are equidistantly arranged inside the side wall of the protective sleeve 2. A plurality of airbags 7 are arranged inside the side wall of the protective sleeve 2. The plurality of airbags 7 are respectively arranged between two adjacent elastic members 4. An anti - corrosion coating 9, a wear - resistant coating 10, an anti - slip coating 11, and an insulation coating 12 are respectively arranged on the outer side of the protective sleeve 2. The operator sleeved the heat - shrinkable tube 1 outside the object to be protected, and then used a hot air gun to heat it, so that the heat - shrinkable tube 1 shrinks to wrap and protect the object. After the heat - shrinkable tube 1 wraps and protects the object, the operator slides the protective sleeve 2 to the outside of the heat - shrinkable tube 1, and heats the two heat - shrinkable members 8 through a hot air gun, so that the heat - shrinkable members 8 shrink and fit tightly with the heat - shrinkable tube 1. When the object is impacted, through the cooperation between the plurality of elastic members 4 and the plurality of airbags 7, impact - resistant protection is provided for the heat - shrinkable tube and the components it wraps, avoiding damage to the object due to excessive impact. At the same time, through the arranged anti - corrosion coating 9, wear - resistant coating 10, anti - slip coating 11, and insulation coating 12, the comprehensive performance of the protective sleeve 2 is significantly improved.

[0023] A plurality of notches 3 are arranged inside the protective sleeve 2. The notches 3 are arranged in a ring shape. The elastic members 4 are arranged inside the notches 3. The notches 3 are used to position the elastic members 4 to prevent the elastic members 4 from sliding randomly inside the side wall of the protective sleeve 2.

[0024] The elastic members 4 are all arranged in a ring shape. A plurality of holes 5 penetrate through the side wall of the elastic member 4. The plurality of holes 5 are distributed in a circular array. By arranging a plurality of holes 5 on the side wall of the elastic member 4, the holes 5 can serve as stress release points to help the elastic member 4 better disperse and absorb energy when impacted.

[0025] Inside the protective sleeve 2, there are multiple positioning grooves 6. The positioning grooves 6 are circular. The airbag 7 is arranged inside the positioning grooves 6, and the airbag 7 is limited by the positioning grooves 6.

[0026] The anti-corrosion coating 9 is located on the outer side of the protective sleeve 2. The anti-corrosion coating 9 uses epoxy resin material. The wear-resistant coating 10 is located above the anti-corrosion coating 9. The wear-resistant coating 10 uses polyurethane material. The epoxy resin material has good corrosion resistance and adhesion, and can effectively resist the erosion of chemical substances. At the same time, the polyurethane material can withstand high-intensity friction and wear, and can maintain long-term durability even in harsh working environments.

[0027] The anti-slip coating 11 is located above the wear-resistant coating 10. The anti-slip coating 11 uses epoxy anti-slip paint. The insulating coating 12 is located above the anti-slip coating 11. The insulating coating 12 uses polytetrafluoroethylene material. The surface of the epoxy anti-slip paint is designed with anti-slip patterns or anti-slip agents added, which can significantly increase the friction coefficient and friction resistance. The polytetrafluoroethylene material has an extremely low dielectric constant and dielectric loss, which means it can still maintain stable insulating performance under high frequency and high voltage.

[0028] In this utility model, the operator sleevs the heat-shrinkable tube 1 outside the object to be protected, and then uses a hot air gun to heat it, so that the heat-shrinkable tube 1 shrinks to wrap and protect the object. After the heat-shrinkable tube 1 wraps and protects the object, the operator slides the protective sleeve 2 to the outside of the heat-shrinkable tube 1, and heats the two heat-shrinkable parts 8 with a hot air gun, so that the heat-shrinkable parts 8 shrink and fit tightly with the heat-shrinkable tube 1. When the object is impacted, through the cooperation between the multiple elastic parts 4 and the multiple airbags 7, anti-impact protection is provided for the heat-shrinkable tube and the components it wraps, avoiding damage to the object due to excessive impact. At the same time, through the multiple holes 5 arranged on the side wall of the elastic part 4, the holes 5 can be used as stress release points to help the elastic part 4 better disperse and absorb energy when being impacted.

[0029] By setting the anti-corrosion coating 9, the corrosion of the external medium to the protective sleeve 2 is prevented, and its service life is extended. By setting the wear-resistant coating 10, the wear resistance of the protective sleeve 2 is improved, and the wear caused by friction is reduced. At the same time, by setting the anti-slip coating 11, the friction coefficient of the surface of the protective sleeve 2 is increased, and slippage during use is prevented. Finally, by setting the insulating coating 12, electrical insulation performance is provided to ensure the safe operation of the equipment, thus significantly improving the comprehensive performance of the protective sleeve 2.

[0030] The above is only the preferred specific embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution and the inventive concept of the present utility model, makes equivalent substitutions or changes, and all should be covered within the protection scope of the present utility model.
