[0021] Example like Figure 1-5As shown, this utility model provides a technical solution: a reinforced aluminum alloy door, including an aluminum alloy door frame 10. Fixed triangular seats 20 are provided at the four corners of the aluminum alloy door frame 10 to specifically reinforce the four corners and prevent corner deformation. Several auxiliary fixing components 30 are also provided inside the aluminum alloy door frame 10 to form multiple supports inside the door frame and strengthen the overall structure. Sound insulation panels 40 are also provided between the auxiliary fixing components 30 to provide sound insulation and space separation. A fixing sleeve 50 is installed inside one of the sound insulation panels 40 for installing observation structure components. External decorative panels 60 are provided inside the aluminum alloy door frame 10 and on both the front and back side walls to enhance the door's decorative appearance. An observation window structure 70 is provided at the connection point of the external decorative panels 60 to realize the door's observation function.

[0022] With the aluminum alloy door frame 10 as the basic frame, the fixed triangular base 20 uses triangular stability to strengthen the four corners of the door frame, and the auxiliary fixing parts 30 construct a multi-layer support structure inside the door frame. Together with the sound insulation board 40, it can improve the structural strength and achieve sound insulation. The fixed sleeve 50 provides the installation base for the observation window structure 70, the outer decorative panel 60 beautifies the surface of the door, and the observation window structure 70 meets the observation needs. The cooperation of all components can comprehensively improve the aluminum alloy door in terms of structural strength, sound insulation, decoration and functionality.

[0023] Four fixed triangular bases 20 are used to reinforce and fix the four corners of the aluminum alloy door frame 10. The stability of the triangular structure is used to disperse the stress at the four corners of the door frame and avoid damage caused by concentrated stress at the corners. Several auxiliary fasteners 30 are used to further reinforce and fix the aluminum alloy door frame 10 and the four fixed triangular bases 20, forming a longitudinal and transverse support system inside the door frame. This connects the door frame and the fixed triangular bases 20 into a whole and enhances the door's resistance to deformation.

[0024] The fixed triangular base 20 reinforces the four corners of the door frame by utilizing the stabilizing properties of a triangle, enabling it to withstand greater external forces. The auxiliary fixing component 30 connects with the fixed triangular base 20 and the door frame inside the door frame to form a three-dimensional reinforcing network, dispersing and transmitting external forces in all directions, effectively improving the structural strength of the door and solving the problems of easy deformation at the four corners and unstable overall structure of existing aluminum alloy doors.

[0025] The auxiliary fastener 30 includes a reinforcing tube 301, which provides the main support as the main structure of the auxiliary fastener 30; a first fixing plate 302 is provided inside the reinforcing tube 301 to form a support inside the reinforcing tube 301; a second fixing plate 303 is provided at the connection of the first fixing plate 302 to cooperate with the first fixing plate 302 to form a cross support; a plurality of filling cavities 304 are provided between the first fixing plate 302 and the second fixing plate 303 to accommodate sound insulation material; sound insulation cotton 305 is provided inside each of the plurality of filling cavities 304 to play a role in sound insulation and noise reduction.

[0026] The reinforcing tube 301 itself has structural strength. The first fixing plate 302 and the second fixing plate 303 inside are arranged in an X-shaped support structure, which greatly improves the bending and torsion resistance of the reinforcing tube 301. At the same time, the sound insulation cotton 305 in the filling cavity 304 absorbs and blocks the sound transmission, so that the auxiliary fixing part 30 has a sound insulation function while strengthening the structure, realizing the dual function of structure and function.

[0027] The first fixing plate 302 and the second fixing plate 303 are installed in an X-shape inside the reinforcing tube 301 to assist in reinforcing the reinforcing tube 301. The X-shaped structural layout divides the internal space of the reinforcing tube 301, so that when the reinforcing tube 301 is subjected to external force, the stress is quickly dispersed to the tube wall, avoiding local stress concentration. The sound insulation cotton 305 is used for sound insulation. Its porous structure absorbs and reflects sound, reducing sound transmission.

[0028] The first fixing plate 302 and the second fixing plate 303 arranged in an X shape form multiple triangular support areas inside the reinforcing tube 301, which effectively resist external forces in different directions and enhance the overall rigidity of the reinforcing tube 301; the sound insulation cotton 305 is filled in the filling cavity 304, and when sound passes through, it is continuously reflected and absorbed in its porous structure, reducing the propagation intensity and achieving the sound insulation effect, so that the auxiliary fixing component 30 has both structural reinforcement and sound insulation functions.

[0029] The outer decorative panel 60 includes two panels 601, which are respectively set on the front and back sides of the door, serving to decorate and protect the internal structure. The outer surface of the panel 601 on the back side is provided with a slot 602 for insertion and mating with the observation window structure 70 component to realize the installation of the observation window. A through slot is also provided at the center of the two panels 601 to accommodate the fixing sleeve 50, so that the fixing sleeve 50 can fit with the outer decorative panel 60 and provide space for the installation of the observation glass 703.

[0030] Two panels 601 cover the front and back of the door, enhancing the appearance and protecting the internal structure; the back panel 601 has a slot 602 for the insertion plate 701 of the observation window structure 70, providing an installation interface for quick installation and disassembly; the through slot allows the fixing sleeve 50 to pass through the outer decorative panel 60, allowing the observation glass 703 to be installed inside the fixing sleeve 50 to realize the observation function, so that the outer decorative panel 60 has both decorative and auxiliary functions for the installation of the observation structure.

[0031] The observation window structure 70 includes a plug plate 701, which is used to cooperate with the plug groove 602 of the outer decorative panel 60 to realize the installation and fixation of the observation window; a connecting seat 702 is provided on the back side wall of the plug plate 701 to fix the observation glass 703; the observation glass 703 is fixed inside the connecting seat 702 to realize the door observation function.

[0032] The plug plate 701 is inserted into the plug groove 602 of the outer decorative panel 60 to achieve a stable connection between the observation window structure 70 and the outer decorative panel 60. The plug-in method facilitates installation and maintenance. The connecting seat 702 fixes the observation glass 703 on the plug plate 701, so that the observation glass 703 is stably installed in the fixing sleeve 50, realizing observation on both sides of the door, meeting the user's observation needs, and improving the practicality of the door.

[0033] The plug plate 701 is plugged into the inside of the plug slot 602, and the observation window structure 70 is connected to the outer decorative panel 60 through the plug-in method. This connection method is simple in structure, convenient to install and stable. The observation glass 703 is installed inside the fixed sleeve 50. The fixed sleeve 50 supports and positions the observation glass 703 stably in the observation position of the door, so as to achieve a clear observation effect.

[0034] The insertion plate 701 and the insertion slot 602 form a reliable mechanical connection, which can withstand a certain external force and ensure that the observation window structure 70 will not easily fall off during use. The observation glass 703 is installed in the fixed sleeve 50, which supports and positions it to keep the observation glass 703 in the correct position, allowing the user to clearly observe the situation on the other side of the door, realizing the observation function and improving the user experience of the door.

[0035] It should be noted that the electrical equipment and components mentioned above are all programmed and controlled using existing PLC controllers. Since these are mature technologies, they will not be described in detail here.

[0036] Although 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 alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
