Description

Technical Field

[0001] This utility model relates to the field of square tube technology, specifically to a male and female structure for square tubes. Background Technology

[0002] Square tubing is a common type of metal tubing, widely used in construction, machinery, and automotive industries. Its production process mainly includes the following steps: First, the raw material strip steel needs to undergo a series of pretreatment processes. The strip steel is unpacked and then its surface is leveled using a leveling machine to remove surface unevenness and impurities. Next, the leveled strip steel is fed into a coiling machine, where it is rolled into a circular tube shape. During this process, the two ends of the strip steel are welded together using a welding machine to form a complete circular tube. Then, the circular tube is fed into a rolling mill, where it is rolled into a square tube.

[0003] When constructing L-shaped square tubes, two square tubes need to be joined together. Traditional methods for connecting square tubes mainly include welding and bolting. While bolting can meet connection requirements to a certain extent, the joint is prone to loosening or deformation under significant pressure or impact, affecting the overall structural stability and safety. Furthermore, over time, bolted connections may further weaken due to vibration or corrosion. Although welding can withstand greater pressure, the two square tubes are prone to misalignment during welding, leading to inconsistent weld quality and potentially welding defects.

[0004] No effective solutions have yet been proposed to address the problems in the relevant technologies. Utility Model Content

[0005] In view of the problems in the related technologies, this utility model proposes a square tube male and female structure to overcome the above-mentioned technical problems existing in the existing related technologies.

[0006] Therefore, the specific technical solution adopted by this utility model is as follows:

[0007] A square tube male-female structure includes a male tube body, a female tube body on one side of the male tube body, a baffle on one end of the male tube body, the baffle abutting against the female tube body, an installation block fixedly connected inside the female tube body, a clamping plate fixedly connected to one side of the installation block, an opening on the male tube body, a fixing groove on the outside of the opening, and the fixing groove matching the clamping plate.

[0008] Furthermore, in order to fix the male and female pipes after they are assembled, and to facilitate welding at the joint, a groove is provided on the fixing groove. A telescopic spring is provided inside the groove. One end of the telescopic spring is connected to the fixing groove, and the other end is connected to the locking post. The fixing groove is provided with a locking post that matches the locking groove.

[0009] Furthermore, in order to secure both sides of the card plate, there are two grooves.

[0010] Furthermore, the fixing groove is fixedly connected to the male pipe body.

[0011] Furthermore, in order to improve the overall strength and durability of the structure and reduce the possibility of deformation, reinforcing ribs are provided on both sides of the opening, and the reinforcing ribs are connected to the male pipe body through a fixing plate.

[0012] Furthermore, the female tube has a notch that matches the male tube.

[0013] Furthermore, in order to improve the corrosion resistance of the male and female pipe bodies, especially in humid or chemically corrosive environments, and to extend the service life of the entire structure, the surfaces of the male and female pipe bodies are coated with an anti-corrosion coating.

[0014] The beneficial effects of this utility model are as follows:

[0015] (1) By setting a baffle on the male pipe body to abut against the female pipe body, and utilizing the design of mounting blocks and clamping plates, precise alignment between the male and female pipe bodies is ensured. Furthermore, by setting telescopic springs, locking posts, and matching grooves and slots, the locking posts automatically enter the grooves after the male and female pipe bodies are aligned, forming a stable connection. This not only helps prevent misalignment during connection but also improves the overall strength and durability of the connection. In addition, since precise alignment and automatic locking are achieved at the connection point, subsequent welding work becomes more convenient and efficient. During welding, the weld seam is more uniform and robust, further improving the safety and reliability of the connection.

[0016] (2) By setting anti-corrosion coatings on the surfaces of the male and female pipes, not only can the metal be protected from environmental factors, but also a variety of color options can be provided to meet different visual needs and make the product more beautiful.

[0025] According to an embodiment of the present invention, a square tube male and female structure is provided.

[0026] Example 1

[0027] like Figures 1-4As shown, the square tube male and female structure according to an embodiment of the present invention includes a male tube body 1, a female tube body 2 on one side of the male tube body 1, a baffle 3 on one end of the male tube body 1, the baffle 3 abutting against the female tube body 2, an installation block 4 fixedly connected inside the female tube body 2, a clamping plate 5 fixedly connected to one side of the installation block 4, an opening 6 on the male tube body 1, a fixing groove 7 on the outside of the opening 6, the fixing groove 7 fixedly connected to the male tube body 1, the fixing groove 7 matching the clamping plate 5, and two grooves 8 on the fixing groove 7 for fixing the two sides of the clamping plate 5. A telescopic spring 9 is provided inside the groove 8, one end of the telescopic spring 9 connected to the fixing groove 7, and the other end connected to the clamping post 10. The fixing groove 7 is provided with... The tube has a retaining post 10 that matches a slot 11. Reinforcing ribs 12 are provided on both sides of the opening 6, and these ribs are connected to the male tube body 1 via a fixing plate 13. This enhances the overall structural strength and durability while reducing the possibility of deformation. A notch 14 is provided on the female tube body 2, matching the male tube body 1. Both the male and female tube bodies 1 and 2 are coated with an anti-corrosion coating 15. This anti-corrosion coating 15 is a powder coating composed of fine solid particles, typically a mixture of resin, pigments, curing agents, and other additives. It is applied to the tube surface via electrostatic spraying or a fluidized bed method, and then melts and cures at high temperature to form a robust and durable coating. It not only provides excellent corrosion resistance but also offers a wide variety of colors, allowing for customization according to customer needs, while also exhibiting good wear resistance and UV resistance. With the above solution, when it is necessary to splice the male tube 1 and the female tube 2, the clamping plate 5 is placed inside the fixing groove 7. At this time, under the action of the inner walls on both sides of the fixing groove 7, the telescopic spring 9 is compressed, which drives the clamping post 10 to move into the groove 8. When the clamping post 10 moves to the clamping groove 11, under the action of the telescopic spring 9, the clamping post 10 will be placed inside the clamping groove 11. At this time, the notch 14 on one end of the female tube 2 is placed on the male tube 1, and the other end of the female tube 2 will abut against the baffle 3, which can accurately align the male tube 1. This not only helps to prevent the two from shifting during connection, but also improves the overall strength and durability of the connection. In addition, since the connection has achieved precise alignment and automatic locking, the subsequent welding work also becomes more convenient and efficient.

[0028] In summary, by utilizing the above-mentioned technical solution of this utility model, a baffle 3 is provided on the male pipe body 1 to abut against the female pipe body 2, and the design of the mounting block 4 and the locking plate 5 ensures precise docking between the male pipe body 1 and the female pipe body 2. Furthermore, by setting a telescopic spring 9, a locking post 10, and matching grooves 8 and slots 11, when the male pipe body 1 and the female pipe body 2 are docked in place, the locking post 10 automatically enters the groove 8, forming a stable connection. This not only helps prevent misalignment during connection but also improves the overall strength and durability of the connection. In addition, since precise docking and automatic locking are achieved at the connection point, subsequent welding work becomes more convenient and efficient. During welding, the weld seam is more uniform and firm, further improving the safety and reliability of the connection. Moreover, by providing an anti-corrosion coating 15 on the surfaces of the male pipe body 1 and the female pipe body 2, not only can the metal be protected from environmental factors, but a variety of color options can also be provided to meet different visual needs, making the product more aesthetically pleasing.
