[0031] As Figure 3As shown, the reinforcing member 2 comprises an outer ring 21, an inner ring 22, a connecting rib 23, a first reinforcing rib 25 and a second reinforcing rib 26, the inner ring 22 is integrally formed with the inner side wall of the outer ring 21 through the connecting rib 23 to form a stable frame structure, the first reinforcing rib 25 is integrally formed with the side wall of the inner ring 22, the second reinforcing rib 26 is integrally formed with the outer side wall of the outer ring 21, the second reinforcing rib 26 is insertedly installed with the end face of the cross groove 12, the first reinforcing rib 25 is in contact with the inner corner of the cross groove 12, and the first reinforcing rib 25 is in contact with the inner corner of the cross groove 12, a plurality of support points are formed inside the aluminum frame 1, the stress applied to the aluminum frame 1 from the outside is dispersed, and the carrying capacity of the aluminum frame 1 is effectively improved.

[0032] It is worth noting that, as Figure 4 shown, the connecting rib 23 is in a trapezoidal structure, which can provide better stability and strength than the ordinary rectangular structure under the condition of the same material consumption, the narrow side of the trapezoidal connecting rib 23 is close to the outer ring 21, and the wide side is close to the inner ring 22, this structure distribution makes the connection between the inner ring 22 and the outer ring 21 more stable, and can more effectively transfer the stress between the inner ring 22 and the outer ring 21, enhance the structural strength of the whole reinforcing member 2, and further improve the overall strength of the aluminum frame 1.

[0033] Further, in order to be able to provide support force to the four sides of the aluminum frame 1, the top surface and the bottom surface of the second reinforcing rib 26 close to the end face position of the cross groove 12 are fixedly connected with a plurality of reinforcing plates 27, the plurality of reinforcing plates 27 are in a triangular structure, the triangular structure has stability, when the aluminum frame 1 is subjected to external force, these reinforcing plates 27 can better transfer and disperse the force to the four sides of the aluminum frame 1, by increasing the reinforcing plates 27, the connection strength and support effect of the second reinforcing rib 26 and the side of the aluminum frame 1 are enhanced, so that the compression resistance and bending resistance of the aluminum frame 1 in various directions are improved, the four sides of the aluminum frame 1 can be more effectively provided with support force, and the deformation of the side of the aluminum frame 1 due to stress is prevented.

[0034] As shown in Figure 2 and Figure 4 shown, in order to be able to increase the oblique support force of the aluminum frame 1, the first reinforcing rib 25 comprises a rib plate 251 and a supporting plate 252, the rib plate 251 and the supporting plate 252 are integrally formed, the rib plate 251 is fixedly connected with the side wall of the inner ring 22, the inner corner of the cross groove 12 is provided with an inclined surface 13, the supporting plate 252 is in contact with the inclined surface 13, when the aluminum frame 1 is subjected to oblique external force, the contact of the supporting plate 252 with the inclined surface 13 can act on the rib plate 251 with oblique force, and transmit to the inner ring 22 and the whole reinforcing member 2 structure, thereby increasing the oblique support force of the aluminum frame 1 and enhancing the stability of the aluminum frame 1 under complex stress conditions.

[0035] In order to be able to select different installation requirements for the aluminum frame 1, the aluminum frame 1 and the reinforcing member 2 can be selectively installed, the end of the second reinforcing rib 26 is provided with a tenon plate 261, the end face of the cross groove 12 is provided with a mortise 11, and the tenon plate 261 is inserted and installed in the mortise 11.

[0036] It is worth noting that, as shown in Figure 4 The side wall of the outer ring 21 is provided with a notch 24, and the first reinforcing rib 25 is arranged in the notch 24. On the one hand, the notch 24 can provide a space for the first reinforcing rib 25 to connect with the inner ring 22, prevent the outer ring 21 from blocking, and ensure that the first reinforcing rib 25 can be stably connected with the inner ring 22. On the other hand, the notch 24 can also make the second reinforcing rib 26 move to the inside of the cross groove 12 when it is excessively stressed, so that the outer ring 21 can be deformed to reduce the gap of the notch 24. This deformation process can absorb part of the energy and play a buffering role, avoiding damage to the reinforcing member 2 or the aluminum frame 1 caused by instantaneous excessive external force, and improving the safety and reliability of the entire structure.
