DETAILED DESCRIPTION

[0026] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0027] like Figures 1 to 5 As shown, an anti-extrusion hexagonal structure wall tube includes a tube body 1, a hexagonal frame 2, a first anti-extrusion mechanism and a second anti-extrusion mechanism; the tube body 1 is sleeved with the hexagonal frame 2, the first anti-extrusion mechanism is arranged at the top and bottom of the hexagonal frame 2, and the second anti-extrusion mechanism is arranged on both sides of the hexagonal frame 2 to support both sides of the tube body 1; the first anti-extrusion mechanism includes a first hinge seat 3, a connecting rod 42, a second hinge seat 41 and a first support plate 4, the first hinge seat 3 is arranged on the left and right sides of the top and bottom of the hexagonal frame 2, two second hinge seats 41 are arranged on the top of the first support plate 4, one end of the connecting rod 42 is hinged to the first hinge seat 3, and the other end is hinged to the second hinge seat 41; a first spring 43 is arranged between the connecting rods 42 on the left and right sides; the first support plate 4 supports the top and bottom of the tube body 1.

[0028] When the pipe body 1 is subjected to external upward and downward extrusion, the connecting rod 42 and the first spring 43 in the first anti-extrusion mechanism are used for buffering. The connecting rod 42 is connected between the hexagonal frame 2 and the first support plate 4 through the first hinge seat 3 and the second hinge seat 41. When the external pressure increases, the connecting rod 42 rotates, and the first spring 43 is compressed, absorbing and dispersing part of the extrusion force; the first support plate 4 directly supports the top and bottom of the pipe body 1 to prevent the pipe body 1 from being deformed or broken due to extrusion; at the same time, the second anti-extrusion mechanism supports both sides of the pipe body 1, enhancing the overall stability of the pipeline.

[0029] Through the design of the hexagonal frame 2 and the double anti-extrusion mechanism, the anti-extrusion ability of the pipeline is significantly improved, enabling it to maintain structural integrity and functional stability under harsh environmental conditions; the durability of the pipeline is enhanced, and the damage and maintenance costs caused by extrusion are reduced, thereby extending the service life of the pipeline; at the same time, it can be applied to a variety of different environments and application scenarios, such as underground pipelines, tunnel projects, etc.

[0030] The second anti-extrusion mechanism includes a second support plate 5, a guide column 6 and a second spring 62. The second support plates 5 are arranged on both sides of the tube body 1. The guide column 6 is arranged on the side of the second support plate 5 away from the tube body 1. One end of the guide column 6 is fixedly connected to the side wall of the second support plate 5, and the other end passes through the hexagonal frame 2, and the guide column 6 is slidably matched with the hexagonal frame 2. Mounting blocks 61 are arranged on the side walls on both sides of the inside of the hexagonal frame 2, and the guide column 6 passes through the mounting block 61. The second spring 62 is sleeved on the guide column 6, and the second spring 62 is located between the mounting block 61 and the second support plate 5; a limiting ring 63 is arranged on the side of the guide column 6 located outside the hexagonal frame 2; the limiting ring 63 is threadedly connected to the guide column 6.

[0031] When the pipe body 1 is squeezed laterally, the second support plate 5 is squeezed and moves along the direction of the guide pillar 6. At this time, the second spring 62 is compressed, absorbing and dispersing part of the squeezing force. As the squeezing force increases, the compression degree of the second spring 62 also increases, thereby providing greater support force to resist squeezing. When the squeezing force disappears or decreases, the second spring 62 returns to its original state, pushing the second support plate 5 back to its original position, and providing continuous support for the pipe body 1.

[0032] Through the design of the second support plate 5, the guide column 6 and the second spring 62, additional lateral support force is provided for the pipe body 1, which significantly improves the anti-extrusion ability of the pipe body 1; enhances the durability of the pipeline, reduces the damage and maintenance costs caused by extrusion, and thus extends the service life of the pipe body 1.

[0033] A first elastic pad 44 is disposed on the side wall of the first support plate 4 facing the pipe body 1 ; a second elastic pad 51 is disposed on the side wall of the second support plate 5 facing the pipe body 1 .

[0034] When the pipe body 1 is squeezed, the first elastic pad 44 and the second elastic pad 51 first absorb and disperse the squeezing force, reducing the pressure directly acting on the pipe body 1. The deformation and recovery process of the first elastic pad 44 and the second elastic pad 51 also consumes part of the energy of the squeezing force, further enhancing the anti-squeezing ability of the pipe body 1. At the same time, the hard contact between the pipe body 1 and the first support plate 4 and the second support plate 5 is reduced, reducing the noise and vibration caused by squeezing.

[0035] By providing the first elastic pad 44 and the second elastic pad 51 , the buffering capacity of the pipe body 1 is significantly enhanced, so that the pipe body 1 can better maintain the structural integrity and functional stability when being squeezed.

[0036] The first support plate 4 has side walls on both sides provided with first rounded corners 45 ; the second support plate 5 has side walls on both sides provided with second rounded corners 52 , and the second rounded corner 52 on one side is arranged opposite to the first rounded corner 45 on one side.

[0037] The first fillet 45 and the second fillet 52 are provided to effectively reduce the friction force generated when the first support plate 4 and the second support plate 5 contact each other, avoid interference between the first support plate 4 and the second support plate 5, and effectively improve the stability of buffering and anti-extrusion.

[0038] A plurality of hexagonal frames 2 are arranged on the tube body 1 .

[0039] The arrangement of multiple hexagonal frames 2 makes the pipe body 1 more stable in structure and better able to resist external pressure; at the same time, the hexagonal frames 2 can support each other to form an integral structure, thereby improving the deformation resistance of the pipe body 1.

[0040] The working principle of the present invention is as follows: when the pipe body 1 is squeezed in the up and down directions from the outside, the connecting rod 42 in the first anti-extrusion mechanism rotates, and the first spring 43 is compressed, absorbing and dispersing part of the squeezing force. The first support plate 4 directly supports the top and bottom of the pipe body 1 to prevent the pipe body 1 from being deformed or broken due to squeezing.

[0041] When the pipe body 1 is subjected to lateral extrusion, the second support plate 5 in the second anti-extrusion mechanism will be subjected to extrusion force and move along the direction of the guide pillar 6; at this time, the second spring 62 will be compressed, absorbing and dispersing part of the extrusion force. As the extrusion force increases, the compression degree of the second spring 62 will also increase, thereby providing greater support force to resist extrusion. When the extrusion force disappears or decreases, the second spring 62 will return to its original state, pushing the second support plate 5 back to its original position, providing continuous support for the pipe body 1.

[0042] At the same time, the arrangement of multiple hexagonal frames 2 makes the pipe body 1 more stable in structure and can better resist external pressure. The hexagonal frames 2 can support each other to form an integral structure, thereby improving the anti-deformation ability of the pipe body 1.

[0043] The above description of the disclosed embodiments enables those skilled in the art to implement or use the present application. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present application. Therefore, the present application will not be limited to the embodiments shown herein, but will conform to the widest scope consistent with the principles and novel features disclosed herein.
