Description

Technical Field

[0001] The utility model relates to the field of aluminum rods, in particular to an aluminum rod with a surface anti-rust structure. Background Art

[0002] Aluminum rods, as a common metal material, are widely used in various industrial fields. However, during storage and use, aluminum rods are susceptible to environmental factors, particularly humidity and oxygen, which can cause surface rust. This not only affects the appearance of the aluminum rods but also reduces their mechanical properties and service life. To address this issue, aluminum rods are typically treated with rust-proofing treatments.

[0003] Traditional rust prevention methods involve coating aluminum bars with anti-rust oil or paint. However, these methods are complex, costly, and often lack long-lasting rust prevention. In particular, if the anti-rust coating becomes damaged or ineffective during storage, the aluminum bars remain vulnerable to corrosion. Therefore, a simpler, more effective, and more durable rust prevention method is needed to protect aluminum bars. Utility Model Content

[0004] The purpose of the utility model is to provide an aluminum rod with a surface rust-proof structure to solve the problems raised in the above background technology.

This not only improves the anti-rust effect, but also extends the service life of the aluminum rod. The anti-rust structure is easy to operate. It only requires the movable ring to be placed on the aluminum rod and slide to achieve the application of the anti-rust oil. Compared with traditional anti-rust methods, it can be dismantled and recycled, saving manpower and time costs. The provision of a flexible protective film cover and a rubber seal further enhances the anti-rust effect of the aluminum rod.

All other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0026] See also Figures 1-9The utility model provides a technical solution: an aluminum rod with a surface rust-proof structure, comprising an aluminum rod body 1, one end of the aluminum rod body 1 is sleeved with a gusset plate 2, one end of the gusset plate 2 is provided with a receiving groove 3, a flexible protective film cover 17 is fixed inside the receiving groove 3, one end of the flexible protective film cover 17 is fixed to the surface of the moving ring 7, the moving ring 7 is sleeved on the aluminum rod body 1, the gusset plate 2 is a circular cover, the receiving groove 3 is a circular groove with a "convex" shape in the fracture, an introduction ring 5 is inserted at the notch of the receiving groove 3, one end of the introduction ring 5 is fixed to the surface of the moving ring 7; the groove of the receiving groove 3 A card groove 4 is provided on the inner ring surface and the outer ring surface of the mouth, and the card groove 4 is a circular groove. The inner ring surface of the introduction ring 5 and the outer ring surface of the introduction ring 5 are fixed with a rubber clamping ring 6, and the two rubber clamping rings 6 are matched with the two introduction rings 5 ​​respectively; the inner ring surface of the movable ring 7 is provided with an embedding groove 8, and the embedding groove 8 is an annular groove. A sponge cover 9 is fixed inside the embedding groove 8, and the sponge cover 9 is an annular plate. The inner ring surface of the sponge cover 9 contacts the surface of the aluminum rod body 1; the inner ring surface of the movable ring 7 and the inner ring surface of the buckle plate 2 are fixed with a rubber ring 18, and the inner ring diameter of the rubber ring 18 is smaller than the rod diameter of the aluminum rod body 1.

[0027] During use, when the movable ring 7 and the buckle plate 2 are close together, the flexible protective film cover 17 is folded and inserted into the storage groove 3 for storage. At this time, the introduction ring 5 extends into the storage groove 3, and the rubber clamping rings 6 on both sides of the introduction ring 5 are squeezed in the two clamping grooves 4 to produce elastic deformation, to prevent the introduction ring 5 from detaching from the storage groove 3 when there is no external force, to complete the assembly of the buckle plate 2 and the movable ring 7, and the movable ring 7 and the buckle plate 2 are mounted on one end of the aluminum rod body 1. At this time, the rubber ring 18 at the inner ring mouth of the movable ring 7 and the aluminum rod body 1 is squeezed to produce elastic deformation, thereby playing an anti-slip role for the buckle plate 2 and the movable ring 7, that is, when there is no external force to tension the buckle plate 2 and the movable ring 7, the buckle plate 2 and the movable ring 7 are mounted on the aluminum rod body 1 and will not slide.

[0028] The interior of the movable ring 7 is provided with an oil storage chamber 10, and the interior of the oil storage chamber 10 is filled with rust-proof oil. The inner ring surface of the movable ring 7 is provided with an oil-repellent hole 11, and the outer ring surface of the movable ring 7 is provided with an oil filling hole 14. The inner ring surface of the oil storage chamber 10 is sleeved and fixed with an oil-absorbing cotton cover 12, and the inner ring surface of the oil-absorbing cotton cover 12 is fixed with an oil-absorbing cotton core 13. One end of the oil-absorbing cotton core 13 passes through the oil-repellent hole 11 and is fixed on the outer ring surface of the sponge cover 9; the oil filling hole 14 is an inverted "convex" shaped circular mouth, and the bottom end notch of the oil filling hole 14 is provided with an internal thread, and a head 15 is inserted into and screwed into the interior of the oil filling hole 14. The head 15 is a "T"-shaped cylinder, and the bottom end of the head 15 is provided with an external thread, and the external thread and the internal thread are matched and connected. The top of the head 15 overlaps the top groove body of the oil filling hole 14, and the surface of the head 15 is provided with micropores for supplying air to the oil storage chamber 10.

[0029] During use, after unscrewing and removing the head 15 from the oil filling hole 14, inject the rust-proof oil into the oil storage chamber 10 through the oil filling hole 14, and then screw the head 15 to seal the oil filling hole 14. The micropores on the surface of the head 15 can replenish air into the oil storage chamber 10, ensuring that the rust-proof oil inside the oil storage chamber 10 is soaked in the oil-absorbing cotton cover 12 and the oil-absorbing cotton core 13 and then transported to the sponge cover 9. During the process of pulling and sliding the movable ring 7 along the aluminum rod body 1, the sponge cover 9 applies the rust-proof oil on the surface of the aluminum rod body 1 until the movable ring 7 moves to the other end of the aluminum rod body 1, and at this time the flexible protective film cover 17 is unfolded and sleeved on the outside of the aluminum rod body 1, isolating external water vapor from contacting the aluminum rod body 1, thereby improving the rust-proof effect of the aluminum rod body 1 during storage.

[0030] A rubber sealing piece 16 is fixed on the side of the moving ring 7 away from the buckle plate 2. The rubber sealing piece 16 is a fan-shaped piece, and there are four rubber sealing pieces 16. When the moving ring 7 moves to the end of the aluminum rod body 1, the four rubber sealing pieces 16 are reset to circular pieces to block the inner ring opening of the moving ring 7; the reason why the rubber sealing piece 16 is installed at one end of the moving ring 7 is that when the moving ring 7 moves to one end of the aluminum rod body 1, multiple rubber sealing pieces 16 block and protect the end face of one end of the aluminum rod body 1. It should be noted that when the moving ring 7 leans against one side of the buckle plate 2, multiple rubber sealing pieces 16 are folded, that is, the rubber sealing pieces 16 are not clamped between the moving ring 7 and the aluminum rod body 1.

[0031] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
