Description

Technical Field

[0001] This utility model relates to the field of heat shrink tubing technology, and in particular to a heat shrink tubing with protective function. Background Technology

[0002] Heat shrink tubing is a functional tubular material with "heat shrinkage" properties. Its core is made of high molecular polymer as the base material and is processed by special technology. It can shrink rapidly when heated and fit tightly to the surface of the object being covered, thereby achieving functions such as insulation, sealing and protection. Heat shrink tubing is widely used in electronics, power, automotive, communications and other fields. It is mainly used for insulation protection of wires and cables, sealing and moisture-proofing of joints, identification of components and rust and corrosion prevention of metal parts.

[0003] When workers need to protect wires, they put heat shrink tubing over the wires and heat it so that the tubing shrinks and protects the wires. However, during use, the wires may bend inside the heat shrink tubing due to compression, which can cause the surface of the heat shrink tubing to crack. Utility Model Content

[0004] The purpose of this invention is to solve the problem of surface cracking in existing heat shrink tubing, and to propose a heat shrink tubing with protective function.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a heat shrink tubing with protective function, comprising a protective tube, wherein a wire is placed inside the protective tube, and a protective device is provided on the surface of the protective tube. The protective device includes connecting straps, two of which are fixedly connected to the surface of the protective tube. A first protective sleeve is fixedly connected to the surface of one of the connecting straps, and a rubber pad on the inner side of the first protective sleeve is fitted onto the surface of the protective tube. A second protective sleeve is fixedly connected to the surface of the other connecting strap, and a rubber pad on the inner side of the second protective sleeve is fitted onto the surface of the protective tube. A first support plate is fixedly connected to the surface of the first protective sleeve, and a second support plate is fixedly connected to the surface of the second protective sleeve. The first support plate is placed on the surface of the second support plate. A connecting assembly is provided on the surfaces of the first and second protective sleeves. The connecting assembly includes a threaded ring, which is threadedly connected to the surfaces of the first and second protective sleeves. The threaded ring is located outside the wire, and can cooperate with the first and second protective sleeves to tighten them.

[0006] Preferably, the surface of the first support plate is fixedly connected with an insert block, and the surface of the second support plate is provided with a storage opening. The insert block is inserted into the inside of the storage opening. The insert block can cooperate with the first support plate to achieve the purpose of fixing the insert block, and the second support plate can cooperate with the storage opening to achieve the purpose of storing the insert block.

[0007] Preferably, the surface of the first protective sleeve is provided with a limiting device, the limiting device including a first rubber sheet, the first rubber sheet being fixedly connected to a rubber pad on the inner side of the first protective sleeve, the first rubber sheet being placed on the surface of the wire, and the first rubber sheet being able to cooperate with the first protective sleeve to achieve the purpose of supporting the first rubber sheet.

[0008] Preferably, a second rubber sheet is fixedly connected to the rubber pad on the inner side of the second protective sleeve. The second rubber sheet is placed on the surface of the wire and is located below the first rubber sheet. The second rubber sheet can cooperate with the second protective sleeve to support the first rubber sheet.

[0009] Preferably, a metal ring is placed on the rubber pad inside the first protective sleeve and the rubber pad inside the second protective sleeve. The metal ring is located on one side of the wire, and the first and second protective sleeves can cooperate with the metal ring to support the metal ring.

[0010] Preferably, the surface of the metal ring is provided with a sleeve opening, which is fitted onto the surface of the first rubber sheet and the second rubber sheet. The sleeve opening and the metal ring can cooperate with the first rubber sheet and the second rubber sheet to restrict the sliding of the first protective sleeve and the second protective sleeve.

[0011] Compared with the prior art, the advantages and positive effects of this utility model are as follows: 1. In this utility model, by setting a protective device, when the worker needs to protect the heat shrink tubing, the worker puts the heat shrink tubing on the wire, pushes the first protective sleeve and the second protective sleeve closer together, the rubber pads on the inner sides of the first and second protective sleeves are put on the wire, the first protective sleeve pushes the first support plate, the first support plate pushes the insert block, the insert block is inserted into the receiving hole opened on the surface of the second support plate, and pushes the threaded ring to contact one end of the first and second protective sleeves. The worker rotates the threaded ring, and the threaded ring is threadedly connected to the surface of the first and second protective sleeves. By setting a protective device, the heat shrink tubing can be effectively protected from being squeezed, and the wire can bend inside the heat shrink tubing, which would lead to the problem of cracking on the surface of the heat shrink tubing.

[0012] 2. In this utility model, by setting a limiting device, when the worker needs to limit the first and second protective sleeves, the worker attaches the first and second rubber pads to the surface of the conductor. The worker pushes the pre-installed metal ring, and the inner opening of the metal ring fits onto the first and second rubber pads. The metal ring abuts against the rubber pads on the inner sides of the first and second protective sleeves. The worker uses a protective tool to squeeze the metal ring, causing the metal ring to deform and press the first and second rubber pads tightly. By setting a limiting device, the worker can effectively limit the first and second protective sleeves, preventing them from sliding on the conductor, thereby improving the stability of the protection device.
