[0002] Environmentally friendly protective sleeves for insulated cables are sheaths made of environmentally friendly materials used to wrap and protect insulated cables. Depending on the material and manufacturing process, they can be divided into various types, such as PVC insulating sleeves, heat-shrink sleeves, and nylon braided sleeves. When using these environmentally friendly protective sleeves, due to their relatively soft material, they can be installed on the outside of the cable using clips for easy installation. However, over time, they are prone to detachment due to aging and corrosion, leaving the cable exposed, which has certain drawbacks. Therefore, we have proposed an environmentally friendly protective sleeve for insulated cables. Utility Model Content

[0004] Therefore, the technical solution adopted by this utility model is as follows: an environmentally friendly protective sleeve for insulated cables, comprising a PVC outer layer, a flame-retardant adhesive layer, a PVC inner layer, a locking block, a fastening assembly, and a fastening plate. The PVC outer layer has a first locking groove and a second locking groove. An insertion hole is provided on the inner side of the first locking groove. The flame-retardant adhesive layer is provided on the inner side of the PVC outer layer. The PVC inner layer is provided on the inner side of the flame-retardant adhesive layer. The locking block is disposed on the PVC outer layer. The fastening assembly includes a stud disposed at the bottom of the locking block and passing through the insertion hole and a fastening knob threadedly connected to the stud. The fastening plate is inserted through the right side of the PVC outer layer.

[0005] Preferably, the outer side of the PVC outer layer is provided with a first flame-retardant coating layer, which is formed by spraying flame-retardant coating.

[0006] Preferably, the flame-retardant adhesive layer is formed by coating with flame-retardant adhesive.

[0007] Preferably, a second flame-retardant coating layer is provided on the inner side of the PVC inner sleeve layer, and the second flame-retardant coating layer is formed by spraying flame-retardant coating.

[0008] Preferably, there are several fastening components and fastening plates.

[0009] Preferably, a limiting block is provided at the top of the fastening plate, and the limiting block is inserted into the second slot of the PVC outer layer.

[0010] By adopting the above technical solution, the beneficial effects achieved by this utility model are as follows: By setting fastening components and fastening plates, this utility model can greatly improve the fixing effect without affecting the use of the environmentally friendly protective sleeve for insulated cables, avoiding the problem of the cable being exposed due to the clip falling off. At the same time, by setting a flame-retardant adhesive layer, the flame-retardant effect can be improved. In use, the user can align the clip with the first slot and snap it in. During the snapping process, the stud of the fastening component will pass through the insertion hole of the PVC outer layer. After passing through, the fastening knob is aligned with the stud and threaded to fix the clip, effectively preventing the problem of the cable being exposed due to the clip falling off the first slot. Then, the fastening plate can be inserted into the right side of the PVC outer layer until the limiting block is inserted into the second slot. After insertion, the right side of the PVC outer layer can be clamped by the fastening plate, which can prevent the clip from falling off the first slot. The fixing effect is excellent.
