Description

Technical Field

[0001] The utility model belongs to the technical field of rolled plates, in particular to a metal rolled plate for anti-corrosion. Background Art

[0002] Aluminum rolled plate refers to aluminum that is stretched into a certain shape under pressure and has the advantage of good corrosion resistance.

[0003] For example, a multi-purpose aluminum rolled plate for accessories disclosed in announcement number CN220280821U includes a first rolled plate and a second rolled plate. The utility model relates to the field of accessory processing technology. The multi-purpose aluminum rolled plate for accessories fixes the first rolled plate and the second rolled plate with screws, which can improve the overall strength of the rolled plate and is suitable for use in environments requiring high strength.

[0004] The applicant found in actual use that since the two rolled plates are fixed with bolts, the two rolled plates need to be aligned before they are fixed. After the alignment, the positions of the rolled plates need to be positioned manually or with the assistance of clamps to prevent deviations between the holes and affect the bolt installation effect (such as slippage or deviation in subsequent installation due to misaligned holes). This is quite inconvenient and cannot meet the users' growing usage needs. Utility Model Content

[0005] The purpose of the utility model is to provide a metal rolling plate for anti-corrosion in order to solve the above-mentioned problems.

[0007] The first rolled plate includes a substrate, and a surface of the substrate is coated with an anti-corrosion layer.

[0008] In a preferred embodiment, the fasteners include four springs and fixing bolts, four corners of the second pressing plate are provided with threaded holes, and the springs are installed in the threaded holes.

[0009] In a preferred embodiment, a light hole is opened on the first rolling plate corresponding to the threaded hole, and the fixing bolt passes through the light hole and is threadedly installed in the threaded hole.

[0010] In a preferred embodiment, the substrate and the second rolled plate are both made of aluminum alloy.

[0011] In a preferred embodiment, the anti-corrosion layer is entirely made of silicon carbide wear-resistant material, and the thickness of the anti-corrosion layer is 1.5-3 μm.

[0012] In summary, due to the adoption of the above technical solution, the beneficial effects of the utility model are:

[0013] 1. In the utility model, a positioning rod and a blind hole for inserting the positioning rod are correspondingly designed between the first and second rolling plates. The blind hole and the positioning rod can realize auxiliary positioning between the first and second rolling plates. When the bolts are subsequently installed, the positioning accuracy between the holes can be guaranteed, and the fixing effect of the bolts can be guaranteed without the need for manual or fixture-assisted fixing;

[0014] 2. In the present invention, by fixing the first rolled plate and the second rolled plate by screws, the overall strength of the rolled plate can be improved, and the utility model is suitable for use in an environment requiring high strength. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0020] Reference Figure 1-3 A metal rolled plate for anti-corrosion includes a first rolled plate 1 and a second rolled plate 2. The first rolled plate 1 and the second rolled plate 2 are stacked up and down and fixed together by fasteners. By fixing the first rolled plate 1 and the second rolled plate 2 by fastener wires, the overall strength of the rolled plate can be improved, and it is suitable for use in an environment requiring high strength.

[0021] Furthermore, the four corners of the bottom end of the first rolling plate 1 are recessed inward to form blind holes 11, and the upper end of the second rolling plate 2 is correspondingly provided with a positioning rod 202 that can be inserted into the blind hole 11. The positioning rod 202 and the blind hole 11 that can be inserted into the blind hole 11 are correspondingly designed between the first rolling plate 1 and the second rolling plate 2. Before installation, the blind hole 11 of the first rolling plate 1 is aligned with the positioning rod 202 and inserted to complete the auxiliary positioning between the first rolling plate 1 and the second rolling plate 2. When the fasteners are installed later, the positioning accuracy between the holes can be guaranteed, thereby ensuring the fixing effect of the subsequent fasteners.

[0022] In addition, the coordination between the positioning rod 202 and the blind hole 11 can also ensure the integrity after subsequent assembly. The positioning rod 202 can be formed by stamping from bottom to top after integral rolling.

[0023] The first rolling plate 1 includes a substrate 101, and the surface of the substrate 101 is coated with an anti-corrosion layer 102. The anti-corrosion layer 102 is made of silicon carbide wear-resistant material as a whole. The thickness of the anti-corrosion layer 102 is 1.5 to 3 μm. The silicon carbide wear-resistant material has special wear resistance and corrosion resistance, and has super wear resistance and corrosion resistance. It also has a very high bonding strength with the metal substrate, and is not easy to fall off while ensuring the overall anti-corrosion effect.

[0024] Furthermore, the fasteners include four springs 4 and fixing bolts 3. The four corners of the second extending plate 2 are provided with threaded holes 201, and the springs 4 are installed in the threaded holes 201. The first extending plate 1 is provided with light holes 12 corresponding to the threaded holes 201. The fixing bolts 3 are threadedly installed in the threaded holes 201 through the light holes 12. After the fixing bolts 3 are tightened, the springs 4 can increase the connecting force and locking force with the fixing bolts 3 to achieve a certain anti-slip and anti-loosening effect, thereby improving the fixing effect of the first extending plate 1 and the second extending plate 2.

[0025] Wherein, the fixing bolt 3 is made of stainless steel.

[0026] Furthermore, the base plate 101 and the second rolling plate 2 are both made of aluminum alloy material.

[0027] In summary, the blind hole 11 and the positioning rod can be used to achieve auxiliary positioning between the first rolling plate 1 and the second rolling plate 2. When the fixing bolts 3 are subsequently installed, the positioning accuracy between the holes can be guaranteed, and the installation effect of the fixing bolts 3 can be guaranteed without the need for manual or clamp-assisted fixing.

[0028] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
