Abstract
Description
Technical Field
[0001] This application relates to the field of steel connector technology, specifically a steel pipe connection structure. Background Technology
[0002] An awning, also known as a sunshade or sun cover, is a structure or device used to block sunlight and provide shaded areas. It is typically installed in outdoor spaces such as patios, balconies, gardens, poolsides, or parking lots to block direct sunlight, reduce ultraviolet radiation, lower temperatures, and create a more comfortable environment. Awnings come in a variety of designs and materials to suit different climate conditions and aesthetic preferences. Common awning materials include canvas, polyester, PVC, aluminum alloy, and wood.
[0003] When constructing a shed, if a steel structure is used as the supporting framework of the shed, it is often necessary to first connect and fix the metal connectors such as steel pipes that are needed for the shed. When connecting the ends of the steel pipes, the existing connection method is mostly welding, which has the problems of low efficiency and poor stability.
[0004] Therefore, this application provides a steel pipe connection structure to solve the above problems. Utility Model Content
[0005] This application provides a steel pipe connection structure, which aims to solve the problems of low efficiency and poor stability in the existing steel pipe connection methods mentioned in the background art, which mostly adopt welding.
[0006] To achieve the above objectives, this application provides the following technical solution: a steel pipe connection structure, including a quick-connect mechanism for connecting a first steel pipe and a second steel pipe:
[0007] The quick-connect mechanism includes a first mating plate fixedly installed at the end of a first steel pipe and a second mating plate fixedly installed at the end of a second steel pipe, opposite to the first mating plate. A first nut is fixedly installed on the first mating plate, and a second nut symmetrically arranged with the first nut is fixedly installed on the second mating plate. A screw rod is threaded between the first nut and the second nut. Thus, when connecting the steel pipe fittings, the first steel pipe is used as a spare. The screw rod is slightly screwed into the first nut on the first mating plate at the end of the first steel pipe. Then, the second steel pipe is taken out, and the second nut on the second mating plate on the second steel pipe is aligned with the other end of the screw rod and screwed in. The first and second steel pipes are then rotated, rotating on the screw rod until the adjacent surfaces of the first mating plate on the first steel pipe and the second mating plate on the second steel pipe come into contact and fit together, completing the fixation. Compared with welding, the bolted connection method is more convenient and faster, has higher construction efficiency, provides stable connection in later use, and has a lower risk of breakage.
[0008] Preferably, to improve robustness, the first butt plate is welded to the end of the first steel pipe and integrally formed with it, and the second butt plate is welded to the end of the second steel pipe and integrally formed with it. This ensures a concentric connection between the first and second steel pipes, improving stability.
[0009] Preferably, to reduce wear, the first nut extends into the first steel pipe, and the second nut extends into the second steel pipe. This protects the threaded surfaces from rapid corrosion and rust during prolonged use, thus extending service life.
[0010] Preferably, for stable connection, the outer wall of the first nut is fitted against the inner wall of the first mating plate, and the first nut is welded to the first mating plate. Similarly, the outer wall of the second nut is fitted against the inner wall of the second mating plate, and the second nut is welded to the second mating plate. This ensures that the mating surfaces of the first and second mating plates are flat, guaranteeing connection stability.
[0011] Preferably, for connecting the screw, the first mating plate has a first through hole adapted to the first nut and the screw, and the second mating plate has a second through hole adapted to the second nut and the screw. Alignment is convenient and quick.
[0012] This connection structure uses a first steel pipe as a spare. The screw is slightly screwed into the first nut on the first mating plate at the end of the first steel pipe. Then, the second steel pipe is taken out, and the second nut on the second mating plate on the second steel pipe is aligned with the other end of the screw and screwed in. The first and second steel pipes are then rotated on the screw until the adjacent surfaces of the first mating plate on the first steel pipe and the second mating plate on the second steel pipe come into contact and fit together, thus completing the fixation. Compared with the welding method, the bolted connection is more convenient and faster, has higher construction efficiency, provides stable connection in later use, and has a lower risk of breakage.
[0013] In this connection structure, the first nut is placed inside the first steel pipe and the second nut is placed inside the second steel pipe, which protects the threaded surface from rapid corrosion and rust during long-term use, thereby improving service life. Attached Figure Description

[0020] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.
[0021] Example 1
[0022] This embodiment provides a steel pipe connection structure, such as Figure 1-4 As shown, the connection structure includes a quick-connect mechanism 3 for docking the first steel pipe 1 and the second steel pipe 2:
[0023] The quick connection mechanism 3 includes a first docking plate 31 fixedly installed at the end of the first steel pipe 1 and a second docking plate 32 fixedly installed at the end of the second steel pipe 2 opposite to the first docking plate 31. A first nut 33 is fixedly installed on the first docking plate 31, and a second nut 34 symmetrically arranged with the first nut 33 is fixedly installed on the second docking plate 32. A screw rod 35 is screwed between the first nut 33 and the second nut 34.
[0024] In use, take the first steel pipe 1 for later use, and slightly screw the screw 35 into the first nut 33 on the first mating plate 31 at the end of the first steel pipe 1. Then take out the second steel pipe 2, align the second nut 34 on the second mating plate 32 on the second steel pipe 2 with the other end of the screw 35 and screw it in. Then rotate the first steel pipe 1 and the second steel pipe 2 in opposite directions and rotate them on the screw 35 until the adjacent surfaces of the first mating plate 31 on the first steel pipe 1 and the second mating plate 32 on the second steel pipe 2 come into contact and fit together, thus completing the fixation. Compared with the welding method, the bolting method is more convenient and faster, has higher construction efficiency, more stable connection in later use, and lower risk of breakage.
[0025] It should be noted that the description of the first steel pipe 1 and the second steel pipe 2 is only for the distinction of steel pipe fittings in this case. In actual use, steel pipe fittings can be set in multiple sections, and the corresponding first connecting plate 31 and second connecting plate 32 can also be set at the ends of different steel pipe fittings to connect multiple sections of steel pipe fittings.
[0026] Specifically, the first connecting plate 31 is welded to the end of the first steel pipe 1 and integrally formed with it, and the second connecting plate 32 is welded to the end of the second steel pipe 2 and integrally formed with it. In use, the first connecting plate 31 is welded to the end of the first steel pipe 1, and the second connecting plate 32 is welded to the end of the second steel pipe 2. The welded surfaces are then ground to ensure a smooth and flat contact surface between the first connecting plate 31 and the second connecting plate 32, ensuring a concentric connection between the first steel pipe 1 and the second steel pipe 2 and improving stability.
[0027] More specifically, the first nut 33 extends into the first steel pipe 1, and the second nut 34 extends into the second steel pipe 2. In use, the first nut 33 is positioned inside the first steel pipe 1, and the second nut 34 is positioned inside the second steel pipe 2, protecting the threaded surfaces from rapid corrosion and rust during prolonged use, thus extending service life.
[0028] Furthermore, the outer wall of the first nut 33 is fitted against the inner wall of the first mating plate 31, and the first nut 33 is welded to the first mating plate 31. The outer wall of the second nut 34 is fitted against the inner wall of the second mating plate 32, and the second nut 34 is welded to the second mating plate 32. In use, the first nut 33 is inside the first steel pipe 1, and the second nut 34 is inside the second steel pipe 2. When mating the first steel pipe 1 and the second steel pipe 2, the first nut 33 and the second nut 34 will not obstruct the mating of the first mating plate 31 and the second mating plate 32, thereby ensuring that the mating surfaces of the first mating plate 31 and the second mating plate 32 are flat and guaranteeing connection stability.
[0029] Furthermore, the first mating plate 31 has a first through hole 36 that matches the first nut 33 and the screw 35, and the second mating plate 32 has a second through hole 37 that matches the second nut 34 and the screw 35. In use, the screw 35 is placed between the first steel pipe 1 and the second steel pipe 2, and its two ends are aligned with the first through hole 36 on the first mating plate 31 and the second through hole 37 on the second mating plate 32, respectively. Then, the first steel pipe 1 and the second steel pipe 2 are rotated to screw the screw 35 into the first nut 33 and the second nut 34, completing the connection between the first steel pipe 1 and the second steel pipe 2. Alignment is convenient and quick.
[0030] The above description is merely a preferred embodiment of this application, but the scope of protection of this application is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this application, based on the technical solution and concept of this application, should be included within the scope of protection of this application.
