Detailed Description

In order that those skilled in the art will better understand the present utility model, a detailed description of embodiments of the present utility model will be provided below, together with the accompanying drawings, wherein it is evident that the embodiments described are only some, but not all, of the embodiments of the present utility model. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.

Reference herein to "an embodiment" means that a particular feature, structure, or characteristic described in connection with the embodiment may be included in at least one embodiment of the utility model. The appearances of such phrases in various places in the specification are not necessarily all referring to the same embodiment, nor are separate or alternative embodiments mutually exclusive of other embodiments. Those of skill in the art will explicitly and implicitly appreciate that the embodiments described herein may be combined with other embodiments.

Referring to fig. 1-5, the present utility model provides a PVE-H composite structure wall-wrapped tube, comprising a base material 1, wherein the base material 1 is sequentially connected after being wrapped to form a hollow tubular structure. In this embodiment, the PVE refers to a composite of PVC and PE, and the H refers to high impact resistance and high loop stiffness.

Further, the base material 1 includes a motherboard 11, and a high rib group 12 disposed on the motherboard 11, wherein the motherboard 11 has a plate-like structure, the high rib group 12 is disposed on the upper surface of the motherboard 11, and the motherboard 11 has a certain length, and the motherboard 11 can be wound into a tubular structure by a winding device.

In a preferred embodiment, the number of the high rib groups 12 is three, including a first high rib 121 disposed in the center, and a second high rib 122 and a third high rib 123 disposed on two sides of the first high rib 121, where one ends of the second high rib 122 and the third high rib 123 are connected to the motherboard 11, and the other ends are connected to two sides of the first high rib 121, respectively, so as to form a hollow wave structure. Through setting up first high muscle 121, second high muscle 122 and third high muscle 123, after substrate 1 twines into tubular structure, on the one hand can effectively improve the ring rigidity of PVE-H composite construction wall winding pipe, on the other hand, PVE-H composite construction wall winding pipe's weight increase degree is relatively lower to transport in the convenience.

Referring to fig. 3 and 4, the height of the first rib 121 is greater than the heights of the second rib 122 and the third rib 123, and the first rib 121 is disposed on one side of the mold plate 11 near the second rib 122, i.e. one end of the second rib 122 is connected to the side of the motherboard 11, and a certain distance is provided between one end of the third rib 123 far from the first rib 121 and the side of the motherboard 11.
