[0056] Example 2

[0057] The following combination Figures 1 to 7To illustrate a specific embodiment of an aluminum alloy furniture provided by the present invention, this embodiment describes in detail the extension direction of the inclined piece 332 based on the embodiment 1:

[0058] The included angle between the extending direction of the inclined piece 332 and the left-right direction x is α, and 30°≤α≤45°.

[0059] Optionally, the angle α between the extending direction of the inclined piece 332 and the left-right direction x can be 30°, 31°, 32.5°, 33°, 34.3°, 35°, 36.4°, 37°, 38.6°, 39°, 40.2°, 41°, 42.2°, 43.3°, 44° and 45°. When α is less than 30°, the angle between the extending direction of the inclined piece 332 and the left-right direction x is smaller. After the aluminum alloy furniture is put into use, the protrusion 33 is affected. The pressure is relatively concentrated, and the connection between the fixed block 3 and the connecting aluminum sheet 5 is prone to shaking during use; when α>45°, the angle between the extension direction of the inclined sheet 332 and the left-right direction x is too large, and the inclined sheet 332 is too inclined and easily bent, resulting in weak stability of the connection between the fixed block 3 and the connecting aluminum sheet 5; when 30°≤α≤45°, the angle between the extension direction of the inclined sheet 332 and the left-right direction x is appropriate, which enhances the stability of the connection between the fixed block 3 and the connecting aluminum sheet 5.

[0060] It can be understood that the inclined piece 332 is arranged around the raised column 331, and the extension direction of the inclined piece 332 is at an angle of 30°-45° to the left-right direction xx. The inclination at a certain angle allows the pressure on the connecting part of the fixed block 3 and the connecting aluminum sheet 5 to be evenly distributed when the aluminum alloy furniture is under pressure, which is less likely to shake and improves the stability of the aluminum alloy furniture.

A cylindrical groove 31 recessed toward the connecting aluminum sheet 5 is also provided on the side of the fixed block 3 away from the connecting aluminum sheet 5, providing a certain basis for the subsequent connection with the connecting block 4;

[0076] It should be noted that the inclined sheet 332 is a plurality of sheet structures, which are alloys after the sheet metal process. There is no clear definition of sheet metal at present.

When α is less than 30°, the angle between the extending direction of the inclined piece 332 and the left-right direction x is smaller. After the aluminum alloy furniture is put into use, the protrusion 33 is affected. The pressure is relatively concentrated, and the connection between the fixed block 3 and the connecting aluminum sheet 5 is prone to shaking during use; when α>45°, the angle between the extension direction of the inclined sheet 332 and the left-right direction x is too large, and the inclined sheet 332 is too inclined and easily bent, resulting in weak stability of the connection between the fixed block 3 and the connecting aluminum sheet 5; when 30°≤α≤45°, the angle between the extension direction of the inclined sheet 332 and the left-right direction x is appropriate, which enhances the stability of the connection between the fixed block 3 and the connecting aluminum sheet 5.

[0107] Example 8

[0108] The following combination Figures 1 to 8 To illustrate a specific embodiment of an aluminum alloy furniture provided by the present invention, this embodiment describes in detail the materials of the detachable connection and layer plate 1, the inclined piece 332, the fixing block 3, the connecting aluminum sheet 5, the connecting block 4 and the column 2 on the basis of the embodiment 7:

[0109] Detachable connection is screw connection

[0110] It can be understood that the screw connection method is basically suitable for various materials, and the installation is simple and convenient. It can be completed without complicated tools and professionals, saving labor costs; the screw connection method has a simple installation process and is also simple and convenient to disassemble. It can be removed by simply rotating the screw; the material cost and installation cost of the screw connection method are relatively low, which is suitable for large-scale production and use; the screw connection can not only meet the fixed connection requirements, but also meet the soft connection requirements, has good strain capacity, and is not easy to break.

[0111] The layer board 1 is a wooden board; the inclined piece 332 is an alloy after sheet metal; the material of the fixing block 3, the connecting aluminum sheet 5, the connecting block 4 and the column 2 is an alloy.

[0112] It can be understood that the wooden layer board 1 has a strong supporting force and is firmly bonded to the connecting aluminum sheet 5, thereby improving the stability of the aluminum alloy clamping distance.

[0113] It is understandable that the sheet metal process can make the metal reach a uniform thickness within the tolerance range after processing, so the protrusion 3312 with the inclined piece 332 can achieve a better effect of dispersing pressure; at the same time, it can also increase the stability of the connection between the connecting aluminum sheet 52 and the fixed block 3 after being connected to the layer plate 17, and the existing problems such as shaking and deformation will not occur.

[0114] Understandably, aluminum alloys have higher strength and can withstand greater forces and strains. Other metal elements such as copper, magnesium, and manganese are added to aluminum alloys to increase the hardness and strength of the material; the other metal elements in aluminum alloys can prevent oxidation on the aluminum surface and effectively resist corrosion from etching and other chemicals; aluminum alloys are easier to process than pure aluminum. Due to the excellent strength, plasticity, and hardness of aluminum alloys, this material can be milled, punched, stamped, and bent more easily. Aluminum alloys are not easily deformed during processing and can better maintain their shape, making them more reliable for use in large-scale production; aluminum alloys are relatively low in cost, reusable, lightweight, and easy to produce. Aluminum alloys are more durable, easier to clean, and can be used for a long time than other materials, which means that using it can reduce maintenance and replacement costs.
