Description

Technical Field

[0001] This utility model relates to the field of heat shrink tubing technology, specifically a heat shrink tubing for power transmission lines with protective functions. Background Technology

[0002] Heat shrink tubing is a new type of environmentally friendly, halogen-free, flame-retardant tubing that provides insulation protection for wires, cables, and wire terminals. It is widely used for insulation protection of wire harnesses, solder joints, and inductors, as well as for rust and corrosion prevention of metal tubes and rods.

[0003] A Chinese patent with publication number CN219106584U discloses a heat shrink tubing with protective function. In use, the mounting slot and mounting strip are connected to facilitate the connection between the heat shrink tubing body and the connector and wire. The heat shrink tubing body protects the connection between the connector and the wire. The design of the heat shrink tubing body provides good protection for the connection. However, it is very susceptible to external damage, such as falling branches or impacts from sand and gravel, which can damage the heat shrink tubing body, thereby reducing its service life and increasing replacement costs. Utility Model Content

[0004] The purpose of this invention is to provide a heat shrink tubing for power transmission lines with protective functions. By using this device, the problem of heat shrink tubing failing to effectively protect itself, resulting in a reduced service life, is solved.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a heat shrinkable sleeve for power transmission lines with protective function, including a connecting component, a heat shrinkable sleeve body disposed on the outside of the connecting component, a self-protection mechanism disposed on the outside of the heat shrinkable sleeve body, four sets of sliding grooves opened on the outer surface of the heat shrinkable sleeve body, and four sets of self-protection mechanisms, all with identical structure and function. Each self-protection mechanism includes a slide rail, which matches and slides along the grooves. An arc-shaped rubber plate is fixedly installed on the outside of the slide rail. During installation, the slide rail is first inserted into the groove, and then a heating device such as a hot air gun is used to heat the heat shrinkable sleeve body to shrink it, thus quickly fixing the grooves and slide rails. Because there are four sets of self-protection mechanisms, the four arc-shaped rubber plates cooperate to fully wrap the outer surface of the heat shrinkable sleeve body, preventing direct contact with the outside environment and creating a barrier effect. The elastic material of the arc-shaped rubber plates achieves a buffering and energy absorption effect, thereby protecting the heat shrinkable sleeve body and extending its service life.

[0006] Preferably, the connecting assembly includes a first wire and a second wire. Insulating sleeves are fixedly installed on the outer sides of both the first wire and the second wire. The insulating sleeves are made of polyvinyl chloride (PVC) material. The insulating sleeves facilitate the initial protection of the first wire and the second wire. PVC material has good insulation properties, which can effectively improve the safety of the first wire and the second wire in use.

[0007] Preferably, a connecting sleeve is fixedly installed at the connection between the first wire and the second wire. The outer surface of the connecting sleeve is provided with multiple positioning grooves. Multiple positioning rings are fixedly installed inside the heat shrink tubing body. The multiple positioning rings correspond one-to-one with the multiple positioning grooves. The opening of the positioning grooves facilitates the quick connection and positioning of the heat shrink tubing body and the connecting sleeve through the positioning rings, and provides precise protection for the connection between the first wire and the second wire.

[0008] Preferably, sealing elements are fixedly installed on the inner sides of both ends of the heat shrink tubing body. The sealing elements include rubber rings, and springs are fixedly installed inside the rubber rings. The springs are installed inside the rubber rings, and the springs continuously generate an outward expansion force on the rubber rings, so that the rubber rings tightly fit the outer surface of the heat shrink tubing body and the connecting sleeve, which greatly improves its sealing performance and effectively prevents moisture from entering and affecting the normal use of wire one and wire two.

[0009] Preferably, an anti-oxidation layer is fixedly installed inside the heat shrink tubing body. The anti-oxidation layer greatly improves the lifespan of the heat shrink tubing body during outdoor use.

[0010] Preferably, the heat shrink tubing body is made of cross-linked polyolefin material, which has advantages such as insulation, corrosion resistance, and wear resistance, further improving the protective performance of the heat shrink tubing body.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] This utility model proposes an intelligent hot stamping and die-cutting machine feeding mechanism. During installation, the slide rail is first inserted into the slide groove, and then the heat shrink tubing body is heated and shrunk using a hot air gun or other heating equipment, which quickly fixes the slide groove and the slide rail. Because the self-protection mechanism is set with four sets, the four arc-shaped rubber plates cooperate to fully wrap the outer surface of the heat shrink tubing body, preventing direct contact with the outside world and forming a barrier effect. The elastic material of the arc-shaped rubber plates achieves a buffering and energy absorption effect, thereby protecting the heat shrink tubing body and extending its service life.
