[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Example 1

[0025] like Figures 1-3 As shown, the aluminum alloy door structure in this embodiment is typically installed on the wall 100 for use. It mainly consists of a main frame 10 located at the corner of the wall 100, a secondary frame 20 located on the other side of the wall 100, a door leaf 30 located between the two main frames 10, and a side panel 40 located between the main frame 10 and the secondary frame 20. The main frame 10 and the secondary frame 20 are made of aluminum.

[0026] Specifically, the main frame 10 includes a first cavity 11, one end of which is provided with a first connecting part 12, and the other end of which is provided with a second connecting part 13. The first connecting part 12 includes a first extension arm 121, and the end of the first extension arm 121 is bent to provide a first connecting arm 122. The first connecting arm 122 abuts against the wall 100. A first positioning plate 123 is provided on the inner side of the first connecting arm 122, and a second positioning plate 124 is provided on the inner side of the first extension arm 121. The inner sides of the first positioning plate 123 and the second positioning plate 124 form a first positioning groove 125. The first extension arm 121 abuts against the wall 100, or can be partially inserted into the wall 100. A bolt can be screwed into the wall 100 at the position of the first positioning groove 125 for locking connection. The first cavity 11 and the first connecting part 12 generally form an L-shaped structure.

[0027] Correspondingly, the second connecting part 13 includes a first snap-fit ​​frame 131 that is generally U-shaped. A second cavity 132 that is generally right-angled triangle is provided on one side of the first snap-fit ​​frame 131. A first mounting frame 133 that is generally U-shaped is provided on the upper end of the second cavity 132. The first mounting frame 133 is used to fill a soundproof sealing strip 134 made of rubber. The two ends of one side of the door leaf 30 are in contact with the soundproof sealing strip 134 to achieve sound reduction.

[0028] Additionally, the sub-frame 20 includes a third connecting part 21 and a fourth connecting part 22 arranged side by side, and a side plate 40 is provided between the second connecting part 13 and the fourth connecting part 22.

[0029] The third connecting part 21 includes a first connecting frame 211 that is generally U-shaped and a second connecting arm 212 disposed on the upper side of one side of the first connecting frame 211. The second connecting arm 212 abuts against the wall 100. Bolts are inserted into the first connecting frame 211 and locked into the wall 100. The fourth connecting part 22 includes a second snap-fit ​​frame 221 that is generally U-shaped. A side plate 40 is inserted between the first snap-fit ​​frame 131 and the second snap-fit ​​frame 221. The side plate 40 is disposed close to the wall 100.

[0030] Here, the inner walls on both sides of the first snap-fit ​​frame 131 and the second snap-fit ​​frame 221 can be provided with a toothed structure to facilitate the engagement of the side plate 40.

[0031] The door panel 30 includes an inner panel and outer panels disposed on opposite sides of the inner panel in the width direction. The inner panel includes a honeycomb core board 31 and wooden boards 32 disposed on opposite sides of the honeycomb core board 31 in the length direction. The wooden boards 32 form a wooden keel structure. The outer panel includes multiple stacked partitions 33. The multi-layer partitions 33 are conventional multi-layer board structures. By combining the aluminum honeycomb core with the wooden boards, strength is ensured and costs are reduced.

[0032] Example 2

[0033] like Figure 4 As shown, in this embodiment, the door leaf 30 also includes an inner panel and outer panels disposed on opposite sides in the width direction of the inner panel. However, the inner panel is composed of a honeycomb core board and aluminum profile keels disposed on opposite sides in the length direction of the honeycomb core board, and the outer panel is a multi-layer board structure with better strength.

[0034] Example 3

[0035] like Figure 5 As shown, in this embodiment, the door leaf 30 also includes an inner panel and outer panels disposed on opposite sides in the width direction of the inner panel. However, the inner panel is composed of a honeycomb core board and aluminum profile keels disposed on opposite sides in the length direction of the honeycomb core board, and the outer panel is a honeycomb board, which has the effects of being lightweight, high-strength, and sound and heat insulation.

[0036] The preferred embodiments of this utility model disclosed above are merely illustrative of the present utility model. These preferred embodiments do not exhaustively describe all details, nor do they limit the utility model to the specific implementations described. Clearly, many modifications and variations can be made based on the content of this specification. This specification selects and specifically describes these embodiments to better explain the principles and practical applications of this utility model, thereby enabling those skilled in the art to better understand and utilize it. This utility model is limited only by the claims and their full scope and equivalents.
