UTILITY MODEL CONTENT
[0004] The utility model provides HDPE inner and outer double muscle reinforced pipe in view of the deficiency of prior art, and specific technical scheme is as follows:
[0005] HDPE inner and outer double muscle reinforced pipe, including HDPE material pipe body, the outside of HDPE material pipe body is arranged in multiple outer reinforcing rib assemblies along the axial direction, the inside of HDPE material pipe body is equipped with multiple inner reinforcing rib assemblies, the outer reinforcing rib includes one annular fixed reinforcing rib and multiple annular movable reinforcing ribs, multiple elastic members are connected between the annular fixed reinforcing rib and adjacent annular movable reinforcing rib and between every two adjacent annular movable reinforcing ribs, the annular movable reinforcing rib is slidingly connected on the outside of HDPE material pipe body, and the annular fixed reinforcing rib is fixedly connected on the outside of HDPE material pipe body.
[0006] As the improvement of the above technical scheme: the outside of HDPE material pipe body is provided with multiple T-shaped sliding grooves along the axial direction, multiple T-shaped sliding grooves are circularly arrayed on HDPE material pipe body, and the inside of annular movable reinforcing rib is slidingly connected with T-shaped sliding groove through sliding block.
[0007] As the improvement of the above technical scheme: the elastic member includes spring and telescopic sleeve rod, and the telescopic sleeve rod is inserted into the inside of spring.
[0008] As the improvement of the above technical scheme: the inner reinforcing rib is strip-shaped reinforcing rib, multiple strip-shaped reinforcing ribs are circularly arrayed on the inside of HDPE material pipe body, each strip-shaped reinforcing rib extends to the axial direction of HDPE material pipe body, and the annular movable reinforcing rib and annular fixed reinforcing rib are made of hard glass fiber reinforcing rib.
[0009] The beneficial effects of this utility model are:
[0010] When installing on a localized area of the HDPE pipe, the annular movable reinforcing rib in the nearby outer reinforcing rib assembly is moved towards the annular fixed reinforcing rib. This brings multiple annular movable reinforcing ribs closer together, reducing the space occupied by the other reinforcing rib assembly in this area. This allows for installation under certain conditions, such as bending, in this area. After installation, the annular movable reinforcing ribs are no longer under stress, and the elastic element resets them, thus resetting the outer reinforcing rib assembly and restoring the rigidity of the HDPE pipe. Therefore, this application can maintain the overall rigidity of the HDPE pipe while facilitating the installation and laying of various areas of the HDPE pipe. During installation, the pipe can be bent and adjusted to a certain extent to adapt to different installation environments and angles, increasing its practical performance.

[0014] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.
[0015] Example
[0016] Please refer to Figures 1-2 The HDPE double-reinforced pipe includes an HDPE pipe body 1. Multiple outer reinforcing ribs are arranged axially on the outer side of the HDPE pipe body 1, and multiple inner reinforcing ribs are provided on the inner side of the HDPE pipe body 1. The outer reinforcing ribs include a fixed annular reinforcing rib 3 and multiple movable annular reinforcing ribs 2. Multiple elastic elements 4 are connected between the fixed annular reinforcing rib 3 and the adjacent movable annular reinforcing ribs 2, as well as between any two adjacent movable annular reinforcing ribs 2. The movable annular reinforcing ribs 2 are slidably connected to the outer side of the HDPE pipe body 1, and the fixed annular reinforcing rib 3 is fixedly connected to the outer side of the HDPE pipe body 1. Specifically, there is a certain gap between adjacent outer reinforcing ribs to facilitate mutual operation.
[0017] In an optional embodiment: the outer side of the HDPE pipe body 1 is provided with a plurality of T-shaped grooves 100 along the axial direction. The plurality of T-shaped grooves 100 are arranged in a circular array on the HDPE pipe body 1. The inner side of the annular movable reinforcing rib 2 is slidably connected to the T-shaped grooves 100 through a slider, so that the annular movable reinforcing rib 2 can move axially and stably on the outer side of the HDPE pipe body 1.
[0018] In an optional embodiment, the elastic element includes a spring 41 and a telescopic rod 42, the telescopic rod 42 being inserted into the inner side of the spring 41. Specifically, the ends of both the spring 41 and the telescopic rod 42 are connected to the side of the annular movable reinforcing rib 2 or the annular fixed reinforcing rib 3.
[0019] In an optional embodiment: the inner reinforcing rib is a strip reinforcing rib 5, and multiple strip reinforcing ribs 5 are arranged in a circular array on the inner side of the HDPE material pipe body 1. Each strip reinforcing rib 5 extends axially towards the HDPE material pipe body 1. The strip reinforcing rib 5 is made of soft TPE thermoplastic elastomer, which can maintain the flexibility of the inner side of the reinforcing rib while reducing the deformation caused by external force. That is, the reinforcing rib can deform while maintaining a certain rigidity. The annular movable reinforcing rib 2 and the annular fixed reinforcing rib 3 are both made of rigid glass fiber reinforced rib GFRP, which is composed of alkali-free glass fiber and resin matrix. It has high tensile strength, light weight and good corrosion resistance, so that the overall strength of the outer side of the HDPE material pipe body 1 can be maintained by multiple annular movable reinforcing ribs 2 and annular fixed reinforcing ribs 3.
[0020] Specifically, during normal use, the elastic force of multiple elastic elements causes multiple annular movable reinforcing ribs 2 and annular fixed reinforcing ribs 3 to spread out from each other, so that multiple annular movable reinforcing ribs 2 and annular fixed reinforcing ribs 3 maintain the overall rigidity of the outer side of the HDPE material pipe body 1, and multiple strip reinforcing ribs 5 can maintain a certain rigidity inside the HDPE material pipe body 1.
[0021] When installing on a local area of the HDPE pipe body 1, the annular movable reinforcing rib 2 in the nearby outer reinforcing rib assembly is moved and pulled towards the annular fixed reinforcing rib 3, causing multiple annular movable reinforcing ribs 2 to move closer together. This reduces the space occupied by the other reinforcing rib assembly in this area, allowing for installation under certain conditions such as bending. After installation, the annular movable reinforcing rib 2 is no longer under stress, and the elastic element 4 resets it, thus resetting the outer reinforcing rib assembly and restoring the rigidity of the HDPE pipe body 1. Therefore, this application can maintain the overall rigidity of the HDPE pipe body 1 while facilitating the installation and laying of various areas of the HDPE pipe body 1. During the installation process, the pipe can be bent and adjusted to a certain extent to adapt to different installation environments and angles, increasing its practical performance.
[0022] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
