[0002] Cylindrical steel is a very common consumable in traditional industries. During production, the whole cylindrical steel is cut into cylindrical steel of a certain length by a cutting machine, and then quantitatively packed by a packing machine, bundling several cylindrical steels into a bundle for transportation. However, this method will cause friction between the cylindrical steels during transportation, resulting in scratches on the surface of the cylindrical steels, and there will be bumps during transportation. Due to inertia, the cylindrical steels will collide with each other, resulting in fine scratches on the cylindrical steels. Content of the Utility Model

[0019] Next, the technical solutions of the present utility model will be clearly and completely described in conjunction with the drawings. Obviously, the described embodiments are part of the embodiments of the present utility model, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without making creative efforts shall fall within the protection scope of the present utility model.

[0020] In the description of the present utility model, it should be noted that the orientation or positional relationship indicated by terms such as "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be construed as a limitation on the present utility model. In addition, the terms "first", "second", "third" are only used for descriptive purposes and cannot be construed as indicating or implying relative importance.

[0021] In the description of the present utility model, it should be noted that unless otherwise clearly specified and defined, the terms "installation", "connection", "coupling" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances. In addition, the technical features involved in different embodiments of the present utility model described below can be combined with each other as long as they do not conflict with each other.

[0022] A spiral protective sleeve for cylindrical steel, as Figures 1 to 5 shown, the spiral protective sleeve 1 is spirally formed by a plastic strip 2 around the axis center;

[0023] The top of the plastic strip 2 bulges upward, and a buffer and rebound groove 3 is opened at the bottom of the plastic strip 2.

[0024] In one embodiment, as Figures 1 to 6 shown, the shape of the buffer and rebound groove 3 is semi-circular.

[0025] In one embodiment, as Figures 1 to 6 shown, the plastic strip 2 includes: an upper friction layer 4, an outer buffer layer 5, a heat insulation and flame retardant layer 6, a fixing layer 7, and an inner anti-slip layer 8;

[0026] The upper friction layer 4, the outer buffer layer 5, the heat insulation and flame retardant layer 6, the fixing layer 7, and the inner anti-slip layer 8 are arranged from outside to inside.

[0027] In one embodiment, as Figures 1 to 6 shown, a plurality of treads are formed on the surface of the upper friction layer 4 to increase the friction between the spiral protective sleeves 1.

[0028] In one embodiment, as Figures 1 to 6 shown, the plastic strip 2 is made of PP material.

[0029] Working principle: The spiral protective sleeve 1 of the utility model is used for the protection of cylindrical steel. It can be assembled manually or by a winding machine. During transportation, the upper friction layer 4 can increase the friction force, thereby reducing the friction between the spiral protective sleeves 1, ensuring stability. At the same time, the outer buffer layer 5 can slightly relieve the pressure of the upper cylindrical steel on the lower cylindrical steel. The fixing layer 7 is used to increase the stress to protect the cylindrical steel and reduce the pressure. The heat-insulating and flame-retardant layer 6 prevents the heat generated by mutual friction during transportation. The inner anti-slip layer 8 can make the spiral protective sleeve 1 and the cylindrical steel stable and not easy to slip. It also has good plastic deformation and memory resilience effect.

[0030] Obviously, the above embodiments are merely examples given for clear illustration and not limitations on the implementation manners. For those of ordinary skill in the art, other different forms of changes or variations can be made based on the above description.
