[0002] Wear-resistant and corrosion-resistant galvanized square tube is a square or rectangular steel tube that has been galvanized. Its surface is covered with a layer of zinc to enhance corrosion resistance. Through galvanizing, these pipes show excellent durability in harsh environments such as moisture, acid and alkali, preventing rust and corrosion. They are usually used in construction, machinery, transportation and other fields. They not only have good structural strength, but also can effectively extend their service life.

[0003] Existing square tubes often face the problem of unprocessed pipe heads at both ends during transportation and storage, which makes them easy to collide and deform during transportation, affecting their use effect. During storage, unsealed pipe heads easily allow corrosive substances such as moisture and dust to enter the interior, causing corrosion of the pipes. Summary of the invention

[0004] The purpose of the utility model is to solve the problem that the square rectangular tubes in the prior art often face the problem of unprocessed tube heads at both ends during transportation and storage, which makes them easy to collide and deform during transportation, affecting their use effect. During storage, the unsealed tube heads easily allow corrosive substances such as moisture and dust to enter the interior, causing the tube to rust. A wear-resistant and corrosion-resistant galvanized square rectangular tube is proposed.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A wear-resistant and corrosion-resistant galvanized square tube comprises a square tube body and a closing plate. A handle is fixedly arranged on the top of the closing plate. The cross-sectional size of the closing plate is not less than the cross-sectional size of the end face of the square tube body.

DETAILED DESCRIPTION

[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0020] In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as a limitation on the present invention.

[0021] Reference Figure 1-3 A wear-resistant and corrosion-resistant galvanized square tube comprises a square tube body 1 and a closing plate 2. A lifting handle 3 is fixedly arranged on the top of the closing plate 2. The cross-sectional dimension of the closing plate 2 is not less than the cross-sectional dimension of the end face of the square tube body 1. The closing plate 2 is used to close the two ends of the square tube body 1. The setting of the lifting handle 3 facilitates the user to transfer the sealing protection structure at both ends of the square tube body 1.

[0022] A rubber pad 4 is fixedly provided at the side edge of the closing plate 2, and a center frame 5 is movably inserted into both ends of the square tube body 1. The side of the center frame 5 is fixedly connected to the side of the closing plate 2, and an expansion support component is provided on the center frame 5 to fix the rubber pad 4 to both ends of the square tube body 1 to protect the two ends of the square tube body 1.

[0023] The expansion and support assembly includes a common screw 7, an expansion and support plate 8, a conical platform 9, and a lifting rod 12. A guide block 11 is movably inserted into the center frame 5. The side of the guide block 11 is fixedly connected to the wide end of the conical platform 9. A threaded hole 6 is opened at the center position of the side of the conical platform 9. The common screw 7 is threaded into the threaded hole 6. A corrugated head 71 is fixedly set at the head of the common screw 7. When the common screw 7 rotates, the conical platform 9 can move along the inside of the center frame 5. The cross-sectional size of the guide block 11 is the same as the cross-sectional size of the center frame 5. The guide block 11 assists the conical platform 9 to move horizontally along the inside of the center frame 5.

[0024] A lifting rod 12 is movably inserted into the four corners of the center frame 5, and an expansion plate 8 is fixedly set at one end of the lifting rod 12. An anti-slip ring 10 is fixedly set on the outer wall of one end of the lifting rod 12 extending into the inner cavity of the center frame 5. The anti-slip ring 10 prevents the lifting rod 12 and the expansion plate 8 from being separated from the center frame 5. The cross-sectional size of the center frame 5 is smaller than the square tube to be inserted. The common screw 7 is rotatably connected to the center of the side of the closing plate 2 at one end away from the conical platform 9. The lifting rod 12 is arranged to form an arc surface 121 close to the anti-slip ring 10, and the side wall of the conical platform 9 is polished into a smooth surface. The setting of the arc surface 121 reduces the wear of the end of the lifting rod 12 when it moves along the side wall of the conical platform 9.

[0025] The specific implementation steps and principles of the utility model are as follows:

[0026] When the entire rectangular tube needs to be transported and the rubber pads 4 are fitted to the two ends of the rectangular tube, the two center frames 5 are inserted into the inner cavity of the square tube body 1, and the corrugated head 71 is rotated manually. The corrugated head 71 is rotated through the common screw 7. Since a threaded hole 6 is provided at the center position of the side of the conical platform 9, the conical platform 9 and the guide block 11 move along the center frame 5. The conical platform 9 drives the four groups of expansion plates 8 to move away from each other through the lifting rod 12, thereby fixing the two groups of rubber pads 4 to the two ends of the rectangular tube.

[0027] The above is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent substitutions or changes within the technical scope disclosed by the present invention according to the technical solution and inventive concept of the present invention, which should be covered by the protection scope of the present invention.
