[0016] The technical scheme in the embodiments of the utility model will be described clearly and completely below in combination with the drawings in the embodiments of the utility model, and apparently, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by the person skilled in the art without creative labor belong to the range of protection of the utility model.

[0017] Referring to Figs. 1-3The utility model provides a plastic winding composite cylinder, the cylinder includes first anticorrosive layer 4, first pressure bearing layer 2, structural layer 1, second pressure bearing layer 3 and second anticorrosive layer 5 in turn from inside to outside, the outer surface of first pressure bearing layer 2 and second pressure bearing layer 3 is staggered and wound with cord 6, and the first pressure bearing layer 2 and second pressure bearing layer 3 are provided with limiting assembly 7, limiting assembly 7 includes slide rod 71, the slide rod 71 is provided with clamping block 73, the clamping block 73 is clamped with limiting block 72, the limiting block 72 is slidably connected with annular plate 74, the annular plate 74 is connected with first pressure bearing layer 2 and second pressure bearing layer 3 through spring, and limiting block 72 is slidably connected with first pressure bearing layer 2 and second pressure bearing layer 3.

[0018] In some embodiments, the limiting block 72 is diamond-shaped. When the operator winds the cord 6 on the first pressure bearing layer 2 and the second pressure bearing layer 3 respectively, the diamond-shaped limiting block 72 allows the operator to stagger the cord 6 along the two sides of the limiting block 72, assisting the operator to wind the cord 6 evenly and neatly without disarray or cord 6 falling off. The operator can pull the limiting block 72 to make the limiting block 72 not be clamped with the clamping block 73, and then rotate the limiting block 72 by ninety degrees to change the wider two sides of the limiting block 72 to the narrower two sides. The spring of the annular plate 74 resets the limiting block 72, making the limiting block 72 be clamped with the clamping block 73, thereby adjusting the distance of the staggered winding of the cord 6.

[0019] In some embodiments, the first anticorrosive layer 4 and the second anticorrosive layer 5 are made of materials such as PP, PE and PPH. PPH is a polymer material, which not only has good toughness, high impact resistance, strong heat resistance, acid and alkali resistance and other physical and chemical properties, but also has the functions of heat-resistant water degradation and no internal stress cracking problem, and is extremely widely used; PP is a semi-crystalline thermoplastic plastic, which has high impact resistance, strong and tough mechanical properties, and resistance to a variety of organic solvents and acid and alkali corrosion, has excellent low-temperature resistance, good chemical stability, and can resist the corrosion of most acids and bases; PE is a thermoplastic resin made of ethylene polymer, which is odorless, nontoxic and has a waxy feel, has excellent low-temperature resistance, good chemical stability, can resist the corrosion of most acids and bases, is insoluble in general solvents at room temperature, has small water absorption and excellent electrical insulation. The above three materials, whether made of a single material or a mixture of multiple materials, have very good impact resistance and corrosion resistance, and improve the overall strength of the cylinder.

[0020] In some embodiments, the limiting block 72 is provided with a groove on the side. When winding the curtain wire 6, the operator can limit the curtain wire 6 through the groove on the side of the limiting block 72, so as to avoid the curtain wire 6 from sliding downward after being wound, causing the winding to be loose, and also guide the curtain wire 6, helping the operator to cross-wind the curtain wire 6, improving the winding efficiency and speeding up the work progress.

[0021] In some embodiments, the limiting block 72 on the first pressure bearing layer 2 is not on the same side as the limiting block 72 on the second pressure bearing layer 3, and each of the limiting blocks 72 on the first pressure bearing layer 2 and the second pressure bearing layer 3 is provided with two groups, and each group is provided with four. The two groups of limiting blocks 72 on the first pressure bearing layer 2 and the second pressure bearing layer 3 are not on the same side, and are respectively located in the four directions of the cylinder, which not only facilitates the operator to quickly wind the curtain wire 6, but also buffers the pressure of the four directions of the cylinder, improves the strength of the cylinder, and the two groups of limiting blocks 72 can help the operator to wind the curtain wire 6 on the first pressure bearing layer 2 more quickly, and improve the work rate of the operator.

[0022] The specific embodiment is only an explanation of the utility model, and is not a limitation of the utility model. Those skilled in the art can make modifications to the embodiment without creative contribution after reading the specification, but as long as it is within the scope of the claims of the utility model, it is protected by the patent law.
