Description

Technical Field

[0001] The utility model relates to the technical field of galvanized iron wires, in particular to anti-aging PVC galvanized iron wires. Background Art

[0002] Galvanized iron wire is divided into hot-dip galvanized wire and cold-dip galvanized wire (electro-galvanized wire). It is made of high-quality low-carbon steel and processed through drawing, pickling and rust removal, high-temperature annealing, hot-dip galvanizing and cooling. A PVC layer is installed on its surface to provide certain protection for the internal iron galvanized layer.

[0003] The utility model patent with authorization announcement number CN219527169U discloses an anti-aging PVC galvanized iron wire. The utility model includes multiple galvanized iron wire bodies, and the multiple galvanized iron wire bodies are intertwined. A friction pad is provided on the outside of the galvanized iron wire body, and a filling layer is filled inside the friction pad and between the multiple groups of galvanized iron wire bodies. An anti-corrosion layer is fixedly connected to the friction pad; by setting the friction pad and the filling layer, the galvanized iron wire body is limited and fixed with the cooperation of the friction pad and the filling layer, thereby ensuring the stability of the galvanized iron wire body inside the friction pad, avoiding the galvanized iron wire body from sliding inside the PVC protective cover during long-term use, and when the PVC protective cover is damaged, the friction pad and the filling layer can provide a certain protection to the internal galvanized iron wire body, preventing the iron zinc plating layer on the surface of the galvanized iron wire body from corroding and exposing the base iron wire, thereby ensuring the service life of the device and achieving anti-aging effect.

[0004] Although the above utility model can achieve the anti-aging effect, in actual use, if the galvanized iron wire is accidentally bent, it will cause the galvanized iron wire to be damaged, which will reduce the service life of the product. In view of this, we propose anti-aging PVC galvanized iron wire. Utility Model Content

[0025] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0026] See also Figure 1-Figure 4 , this embodiment provides a technical solution:

[0027] Anti-aging PVC galvanized iron wire includes a galvanized iron wire body 1, which is wrapped with a protective layer 2. The protective layer 2 includes an inner protective layer 21, an outer protective layer 22 arranged on the outside of the inner protective layer 21, a filler 24 filled in the inner protective layer 21, and a coating 23 applied to the outer surface of the outer protective layer 22. The inner protective layer 21 includes an inner rubber layer 211 wrapped around the outside of the galvanized iron wire body 1 and a braided layer 212 arranged on the outside of the inner rubber layer 211. Through the above-mentioned mechanism, the galvanized iron wire body 1 can be effectively prevented from excessive bending, which affects the service life of the galvanized iron wire.

[0028] Furthermore, the outer protective layer 22 includes an anti-corrosion layer 221, a PVC protective cover 222 sleeved on the outside of the anti-corrosion layer 221, and a buffer pad 223 sleeved on the outside of the PVC protective cover 222, and multiple protections are provided to extend the service life of the galvanized iron wire.

[0029] Furthermore, the galvanized iron wire body 1 is composed of multiple strands of galvanized iron wire bodies 1 twisted together, and the filler 24 is made of hemp rope to increase the roundness of the interior.

[0030] In this embodiment, the material used for the braided layer 212 is polypropylene. The braided layer 212 is tightly wound and fixed on the outside of the inner rubber layer 211 , so that the braided layer 212 can limit the bending of the galvanized iron wire body 1 .

[0031] In this embodiment, the coating 23 is made of a material that can reflect ultraviolet rays, that is, a heat-reflective coating, to reduce the impact of sunlight on the product.

[0032] In this embodiment, the anti-corrosion layer 221 is made of chloroprene rubber, and the buffer pad 223 is sealed and wrapped around the outside of the PVC protective cover 222 to prevent sunlight from passing through and irradiating the PVC protective cover 222 .

[0033] In this embodiment, the outer surface of the buffer pad 223 is roughened, ie, polished with sandpaper, to facilitate the adhesion of the coating 23 .

[0034] In this embodiment, the galvanized iron wire body 1 is wrapped with an inner rubber layer 211, a braided layer 212, an anti-corrosion layer 221, a PVC protective cover 222 and a buffer pad 223 from the inside to the outside. The outer surface of the buffer pad 223 is coated with a coating 23. The galvanized iron wire body 1 is protected by multiple protective layers to ensure that the galvanized iron wire body 1 can be used for a long time.

[0035] It is worth mentioning that the structure and working principle of the buffer pad 223 involved in this embodiment are technologies that have been disclosed in the prior art and will not be described in detail here.

[0036] During the specific use of the anti-aging PVC galvanized iron wire of this embodiment, when it is exposed to sunlight, the heat-reflective coating applied on the coating 23 will reduce the impact of sunlight on the service life of the galvanized iron wire body 1. When it is hit, the buffer pad 223 and the PVC protective cover 222 will reduce the impact of the impact on the service life of the galvanized iron wire body 1. The anti-corrosion layer 221 can prevent the environment from corroding the galvanized iron wire body 1, and the braided layer 212 can prevent the galvanized iron wire body 1 from being bent excessively, which may cause the galvanized iron wire body 1 to be unable to be used normally.

[0037] The above shows and describes the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely preferred examples of the present invention and are not intended to limit the present invention. Various changes and improvements may be made to the present invention without departing from the spirit and scope of the present invention, and such changes and improvements fall within the scope of the present invention.
