[0039] To make the objectives, technical solutions, and advantages of the present invention clear and complete, the embodiments of the present invention will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only some, not all, embodiments of the present invention, and are merely illustrative of the embodiments of the present invention. They are not intended to limit the embodiments of the present invention. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0040] Example 1

[0041] Please see Figures 1-2This invention provides a technical solution: a low-temperature resistant and antifreeze aluminum rod, comprising an aluminum rod body 1, the surface of which is sequentially laminated with an anti-oxidation layer, an antifreeze layer, a thermal insulation layer, and a corrosion-resistant layer. Both ends of the aluminum rod body 1 are provided with side grooves 2, and sleeve plates 3 are fitted inside the side grooves 2. A storage groove 15 is provided on the surface of the sleeve plate 3, and a protective cover 16 is fixed inside the storage groove 15. One end of the protective cover 16 is fixed to the surface of a storage rack 17, and a connecting plate 18 is fixed to the surface of the storage rack 17. A magnetic ring 20 is embedded in the surface of the connecting plate 18. Two sets of... The magnetic ring 20 on the surface of the connecting plate 18 is an opposite magnet. After the two sets of connecting plates 18 are attracted, the protective cover 16 unfolds and wraps around the aluminum rod body 1. By sequentially bonding an anti-oxidation layer, an antifreeze layer, a heat insulation layer and a corrosion-resistant layer to the surface of the aluminum rod body 1, the low-temperature resistance of the aluminum rod itself is improved. Furthermore, the protective cover 16 is fitted on the outside of the aluminum rod body 1 to prevent the functional layers from being scratched and worn, thus affecting the low-temperature resistance of the aluminum rod body 1. This further solves the problem that the existing aluminum rod cannot guarantee the structural stability of the aluminum material when stored in a low-temperature environment, and can improve the low-temperature resistance of the aluminum material.

[0042] Example 2

[0043] See attached document Figure 12 and Figure 13 Based on Embodiment 1, in order to achieve the upright stacking of two aluminum rod bodies 1, the side groove 2 is an annular groove, the sleeve plate 3 is an annular plate structure, and the outer ring surface of the sleeve plate 3 has four planes 22, which are arranged in a "+" shape. The surface of the plane 22 on the top surface of the sleeve plate 3 is fixed with a stacking block 23, the width of the stacking block 23 is smaller than the width of the plane 22, and the surface of the plane 22 on the bottom surface of the sleeve plate 3 is provided with a stacking groove 24. The stacking groove 24 and the stacking block 23 are matched. After the two aluminum rod bodies 1 are stacked, the stacking block 23 is inserted into the stacking groove 24.

[0044] When the sleeve plate 3 is installed at the end of the aluminum rod body 1, and two aluminum rod bodies 1 are stacked, the stacking block 23 on the top surface of the lower set of sleeve plates 3 is inserted into the stacking groove 24 at the bottom of the lower set of sleeve plates 3 to prevent the two stacked aluminum rod bodies 1 from sliding sideways, thereby ensuring that multiple aluminum rod bodies 1 are stacked in alignment without tipping over; this further solves the problem that the existing aluminum rods cannot guarantee the structural stability of aluminum materials when stored in low-temperature environments, and can improve the low-temperature resistance of aluminum materials.

[0045] Example 3

[0046] See attached document Figures 3 to 5 , Figures 7 to 11Based on Embodiment 2, in order to fix the sleeve plate 3 to the end of the aluminum rod body 1, the surface of the sleeve plate 3 is provided with an assembly groove 5, which is an annular groove. Multiple through holes 6 are provided on the inner annular surface of the assembly groove 5. A clamping block 7 is movably inserted into the through holes 6. One end of the clamping block 7 extending into the assembly groove 5 has a bevel facing the opening of the assembly groove 5. A rubber gasket 10 is fixed to the other end of the clamping block 7. A buckle plate 11 is movably inserted into the assembly groove 5, and the buckle plate 11 presses against the clamping block 7 to clamp the side groove 2. A through hole 8 is provided on the surface of the clamping block 7, and a rubber gasket is movably inserted into the through hole 8. The traction belt 9 and the rubber traction belt 9 are respectively fixed at both ends to the two parallel side walls of the perforation 6. When the buckle plate 11 squeezes the clamping block 7 to clamp the side groove 2, the rubber traction belt 9 is in a stretched deformation state. The buckle plate 11 has a circular frame structure. A reserved opening 12 is provided on the circular surface of the buckle plate 11. The reserved opening 12 is square. A limiting shaft 13 is inserted into the reserved opening 12. The limiting shaft 13 is a "T"-shaped square column. One end of the limiting shaft 13 is fixed to the surface of the sealing plate 4. A spring 14 is sleeved on the rod of the limiting shaft 13. The spring 14 is fixed between the buckle plate 11 and the end plate of the limiting shaft 13.

[0047] After the sleeve plate 3 is fitted onto the side groove 2 and the buckle plate 11 is inserted into the assembly groove 5, the clamping block 7 is pressed and clamped by the buckle plate 11 to fix the sleeve plate 3 to the end of the aluminum rod body 1. At this time, the spring 14 is in the initial state, and the rubber traction belt 9 is stretched by the clamping block 7 to produce elastic deformation. When it is necessary to remove the sleeve plate 3 from the side groove 2, two fingers hook the two pull rings 25 respectively, and pull the pull rings 25 to pull the buckle plate 11 away from the assembly groove 5. At this time, the spring 14 is stretched. When the buckle plate 11 is blocked by the end plate of the limiting shaft 13, the buckle plate 11 no longer presses the clamping block 7, and the rubber traction belt 9 rebounds and pulls the clamping block 7 to retract into the assembly groove 5. That is, the clamping block 7 no longer clamps the side groove 2, and the sleeve plate 3 can be pulled out from the side groove 2. This further solves the problem that the existing aluminum rod cannot guarantee the structural stability of the aluminum material when stored in a low temperature environment, and can improve the low temperature resistance of the aluminum material.

[0048] Example 4

[0049] Based on Example 3, the corrosion-resistant layer is proposed to be composed of the following components by weight: 5.3 parts epoxy resin, 1.4 parts hydroxyethyl cellulose, 0.7 parts barium petroleum sulfonate, 1.2 parts talc, 0.6 parts glyceryl monostearate, and 0.3 parts vinyltrimethoxysilane; the antifreeze layer is a linear epoxy antifreeze coating layer with a thickness of 0.5-1.5 mm; this further solves the problem that existing aluminum rods cannot guarantee the structural stability of aluminum materials when stored in low-temperature environments, and can improve the low-temperature resistance of aluminum materials.

[0050] Example 5

[0051] Based on Example 4, refer to Appendix Figure 6 To achieve the connection and positioning of the two sets of connecting plates 18, the storage slot 15 is an annular groove, and the storage rack 17 is a circular rack with a "U" shaped cross section. The storage rack 17 is movably inserted into the storage slot 15. A rubber ring 21 is fixedly fitted on the outer ring surface of the storage rack 17. After the storage rack 17 is inserted into the storage slot 15, the rubber ring 21 is clamped between the storage rack 17 and the storage slot 15 and deforms. The surface of the connecting plate 18 is provided with an insert groove 19, which is an annular groove. A magnetic ring 20 is fixed on the surface of the insert groove 19. A pull ring 25 is fixed on the surface of the buckle plate 11. There are two pull rings 25, which are symmetrically distributed about the reserved opening 12.

[0052] When the two connecting plates 18 are attracted by the magnetic ring 20, the protective cover 16 unfolds and wraps around the outside of the aluminum rod body 1, providing protection for the aluminum rod body 1. When the protective cover 16 is not needed, the protective cover 16 is inserted into the groove of the storage rack 17, and then the storage rack 17 is inserted into the storage slot 15. At this time, the rubber ring 21 is clamped between the storage slot 15 and the storage rack 17 to prevent the storage rack 17 from falling off the storage slot 15 at will. This further solves the problem that the existing aluminum rod cannot guarantee the structural stability of the aluminum material when stored in a low-temperature environment, and can improve the low-temperature resistance of the aluminum material.

[0053] Example 6

[0054] A manufacturing process for low-temperature resistant and freeze-proof aluminum rods, the manufacturing process comprising the following steps:

[0055] Step 1, Mixing powder: Prepare the ingredients according to the proportions, and then mix the ingredients in a three-dimensional rotary powder mixer.

[0056] Step 2, cold pressing: The mixed powder is cold pressed into powder rods on a cold press;

[0057] Step 3, Atomization and Powder Making: The cold-pressed powder rods are induction melted without a crucible in an atomization and powder making furnace. The melt formed by the melting of the rods automatically flows into the atomization nozzle system, and then the atomizing gas is turned on to atomize the melt and make powder.

[0058] Step 4, Annealing: Anneal the atomized powder at 1000-1200℃ under argon protection for 2-3 hours; Step 5, Ball milling: The annealed powder is ball milled in a planetary ball mill to obtain TiB2 fine powder.

[0059] Step 6, Thermal spraying: Using a steel rod as a base, the TiB2 fine powder obtained by ball milling is sprayed onto the steel rod by thermal spraying to obtain a low-temperature resistant and freeze-proof aluminum rod.

[0060] In actual use, when the sleeve plate 3 is installed at the end of the aluminum rod body 1, and two aluminum rod bodies 1 are stacked, the stacking block 23 on the top surface of the lower set of sleeve plates 3 is inserted into the stacking groove 24 at the bottom of the lower set of sleeve plates 3 to prevent the two stacked aluminum rod bodies 1 from slipping sideways, thus ensuring that multiple aluminum rod bodies 1 are stacked in alignment without tipping over. After the sleeve plate 3 is fitted onto the side groove 2 and the buckle plate 11 is inserted into the assembly groove 5, the clamping block 7 is squeezed and clamped by the buckle plate 11 to fix the sleeve plate 3 to the end of the aluminum rod body 1. At this time, the spring 14 is in its initial state, and the rubber traction band 9 is stretched by the clamping block 7 to produce elastic deformation. When it is necessary to remove the sleeve plate 3 from the side groove 2, two fingers hook the two pull rings 25 respectively, and pull the pull rings 25 to pull the buckle plate 11 away from the side groove 2. As the assembly slot 5 moves in the direction, the spring 14 is stretched. When the buckle plate 11 is blocked by the end plate of the limiting shaft 13, the buckle plate 11 no longer squeezes the clamping block 7. The rubber traction belt 9 rebounds and pulls the clamping block 7 into the assembly slot 5, that is, the clamping block 7 no longer clamps the side slot 2. The sleeve plate 3 can be pulled out from the side slot 2. When the two connecting plates 18 are attracted by the magnetic ring 20, the protective cover 16 unfolds and wraps around the outside of the aluminum rod body 1, which protects the aluminum rod body 1. When the protective cover 16 is not needed, the protective cover 16 is inserted into the slot of the storage rack 17, and then the storage rack 17 is inserted into the storage slot 15. At this time, the rubber ring 21 is clamped between the storage slot 15 and the storage rack 17 to prevent the storage rack 17 from falling off the storage slot 15 at will. Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
