Description

TECHNICAL FIELD

[0001] The application relates to the technical field of manufacturing and processing of metal pipes, in particular to a reinforced anti-twist special-shaped pipe. BACKGROUND

[0002] In traditional steel pipe applications, whether circular, square or rectangular cross-section steel pipes, stability is usually ensured by relying on their own structural strength. However, in actual use, these steel pipes generally have the problem of poor structural stability and flexibility. The traditional solution is usually to increase the wall thickness of the steel pipe or use a stronger material to improve its stability. But this method increases the self-weight and cost of the steel pipe, and also reduces its adaptability in changing environments. CONTENT OF THE UTILITY MODEL

[0003] The application aims to provide a pipe bending device which is simple in structure, convenient to operate and capable of simultaneously fixing and processing multiple seamless stainless steel pipes. To achieve the above-mentioned purpose, the application provides the following technical scheme: a reinforced anti-twist special-shaped pipe comprising:

[0004] a pipe body, the cross-section of the pipe body being a H-shaped section formed by connecting two symmetrical upper and lower circular arcs and two symmetrical grooves;

[0005] an inner lining layer, the inner lining layer being compounded on the inner side of the pipe body;

[0006] a reinforcing rib, the reinforcing rib being arranged in the inner lining layer and being uniformly distributed along the axial direction of the pipe body, the reinforcing ribs being crossed with each other in the cross-section to form a grid structure;

[0007] a square hole, the square hole being arranged at the bottom of the groove and being a through hole for inserting a square pin and fixing other structures.

[0008] Preferably, the middle section of the circular arc is arched outwardly to form a protrusion in the cross-section of the pipe body.

[0009] Preferably, a plurality of square holes are uniformly arranged along the bottom of the groove.

[0010] Preferably, the technical scheme further comprises a threaded hole, the threaded hole being arranged at the bottom of the groove and having an internal thread.

[0011] Preferably, the technical scheme further comprises a gasket, the gasket being arranged at the bottom of the groove and being adapted to the threaded hole.

[0012] Preferably, the technical scheme further comprises a buckle, the buckle being arranged at both ends of the groove.

[0013] Preferably, the buckle is detachably connected.

[0014] Compared with the prior art, the application has the following beneficial effects:

[0015] The reinforced anti-torsion special-shaped pipe provided by the application has the advantages of simple structure, easy manufacturing, easy installation and maintenance, and the like. The pipe body cross section is designed as a H-shaped structure formed by two upper and lower symmetrical circular arcs and two left and right symmetrical grooves, which optimizes the mechanical properties of the pipe material and improves the anti-torsion capability. In addition, the application of the inner lining layer to the inner side of the pipe body further enhances the stability of the pipe material. Moreover, the existence of the inner lining layer enables the pipe material to better resist medium corrosion during use, thereby prolonging the service life of the pipe material. The reinforcing ribs are arranged in the inner lining layer and are uniformly distributed along the axial direction of the pipe body. The reinforcing ribs intersect with each other in the cross section to form a grid structure, which greatly improves the compressive strength and impact resistance of the pipe material. When subjected to external pressure or impact, the reinforcing ribs can effectively disperse and relieve stress to protect the pipe body from damage. The square hole arranged at the bottom of the groove serves as a through hole for the square plug to facilitate the fixed connection with other structures and enhances the bonding force between the pipe material and the overall structure. This design not only improves the applicability of the pipe material, but also simplifies the installation process and saves the installation cost. BRIEF DESCRIPTION OF DRAWINGS

[0018] The technical solutions in the embodiments of the application will be clearly and completely described below with reference to the drawings in the embodiments of the application. Obviously, the described embodiments are only part of the embodiments of the application, rather than all the embodiments of the application. Based on the embodiments in the application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the application.

[0019] It should be noted that, in the description of the application, the terms "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", and the like indicate the orientation or positional relationship shown in the drawings, and are only used to facilitate the description of the application and simplify the description, and do not indicate or imply that the devices or elements referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as a limitation on the application.

[0020] Furthermore, it should be understood that, for ease of description, the dimensions of the various components shown in the accompanying drawings are not drawn to actual scale; for example, the thickness or width of some layers may be exaggerated relative to other layers.

[0021] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined or described in one figure, it will not need to be discussed or described in detail in the description of the subsequent figures.

[0022] To further understand the technical solution, it's first necessary to understand the application scenarios of this application. In industrial buildings, especially in steel structure engineering, this shaped tube can serve as an internal secondary support column structure, providing strong support by utilizing its high torsional resistance and stability. The I-beam structure and reinforcing ribs enable it to withstand heavy loads and complex mechanical loads, while the inner lining protects the tube from environmental corrosion.

[0023] In order to solve the technical problems in the background art, such as Figure 1 As shown, this application provides a technical solution: a reinforced anti-torsion shaped tube, characterized as follows:

[0024] The main body 1 can be made of stainless steel, with an I-shaped cross-section, specifically formed by two symmetrical arc segments 2 connected by two symmetrical grooves 3. This design provides good mechanical properties and torsional resistance. The inner lining 4 can be made of polyethylene, polypropylene, or other polymer materials, bonded to the inside of the main body 1 through processes such as hot melting, bonding, or injection molding. The inner lining 4 provides additional corrosion resistance and wear resistance, and also serves as a carrier for the reinforcing ribs 5, enhancing the overall structural stability. The reinforcing ribs 5 are made of high-strength materials such as glass fiber reinforced plastic or carbon fiber reinforced plastic, and are evenly distributed along the axis of the main body 1 within the inner lining 4. The reinforcing ribs 5 intersect each other in cross-section, forming a grid structure, which significantly improves the torsional resistance and overall rigidity of the main body 1. The layout and spacing of the reinforcing ribs 5 are precisely calculated and designed to ensure maximum strength and rigidity without adding excessive weight. Square holes 6 are located at the bottom of the grooves 3. These square holes 6 are through holes that extend throughout the entire shaped tube, and are used to insert square pins for fixing to other structures.

[0025] When used, if the shaped tube is placed horizontally, it can be used as a window base for industrial buildings, and the window structure can be installed in the groove 3 part; if the shaped tube is placed vertically, it can be used as a partition column, and its groove 3 part is connected to the door frame, so it has good adaptability.

[0026] Further, the convex design increases the cross-sectional area of the pipe body 1, thereby improving its bending resistance, making the pipe more stable under bending loads. The convex part can serve as a local reinforcement, improving the stability of the pipe body 1 in specific areas, which is particularly important for bearing concentrated or impact loads. When subjected to external forces, the convex part can help to distribute stress more evenly, reducing stress concentration, thereby improving the overall strength of the pipe.

[0027] It should be noted that the uniform distribution of square holes 6 allows the pipe to be connected with various structural members, improving the versatility and applicability of the pipe. The uniform distribution of square holes 6 simplifies the installation process, as they provide multiple fixing points for installation, reducing the need for on-site measurement and drilling. The uniform arrangement of square holes 6 helps to distribute loads more evenly during connection, reducing local stress concentration and improving the overall stability of the structure. Various installation options are provided, allowing the selection of the most suitable connection position according to actual needs.

[0028] It is worth noting that the threaded holes 7 are arranged at the bottom of the grooves 3, together with the square holes 6, to provide multiple fixing and connecting methods for the pipe. The threaded holes 7 have internal threads, which allow the use of bolts, screws or other threaded connectors to directly connect with the pipe without the need for additional connectors.

[0029] It should be noted that the gaskets 8 are arranged at the bottom of the grooves 3, matching the threaded holes 7, to provide additional protection for the pipe. The size and shape of the gaskets 8 are designed to fit precisely with the threaded holes 7, ensuring good fastening effect during connection. The gaskets 8 can be made of rubber, plastic, metal or other suitable materials. The main function of the gaskets 8 is to act as a buffer and shock absorber.

[0030] It is worth noting that the buckles 9 are arranged at both ends of the grooves 3, used to fix and lock the connection of the pipe with other structures or to connect different types of pipes through the connecting structure, thereby realizing the extension of the special-shaped pipe. The buckles 9 can be made of plastic, metal or other durable materials to ensure their reliability in various environments. The main function of the buckles 9 is to provide a quick fixing and releasing mechanism, facilitating installation and maintenance. The buckles 9 can be fixed in place by mechanisms such as clamping slots, springs or elastic elements, ensuring the stability of the connection.

[0031] It is worth noting that the buckles 9 can be designed to be detachable, with holes at the bottom of the grooves 3 to connect the buckles 9, and the tail of the buckle 9 is provided with a protruding structure matching the hole. The detachable buckles 9 make it easier to maintain and inspect the pipe, as they can be quickly removed without damaging the connection. If there is no need to connect different types of pipes for extension, the buckles 9 can be removed.

[0032] While embodiments of the application have been shown and described, it is to be understood that the embodiments described are merely exemplary and that changes can be made in detail without departing from the principles and spirit of the application. The scope of the application is therefore defined by the appended claims and their equivalents.
