[0002] Aluminum alloy swing door refers to a swing door made of aluminum alloy. In addition to the characteristics of ordinary swing doors, aluminum alloy swing doors also have the advantages of aluminum alloy materials, such as corrosion resistance, wear resistance, lightness and beauty. At the same time, aluminum alloy swing doors can also be surface-treated as needed, such as spraying, anodizing, etc., to improve their decorativeness and durability. The doors used inside the tent are usually simple door curtains, which are inconvenient to use. In addition, the acrylic panels of existing aluminum alloy swing doors are usually fixed to the door leaves with screws during installation, which is inconvenient to replace the acrylic panels.

[0003] In order to solve the above problems, a utility model patent with publication number CN216767125U discloses an aluminum alloy swing door, which is used as an interlocking door inside a tent, so that a single tent can maintain good privacy. By pulling the first moving rod and compressing the first spring, the first fixing ring is pulled out from between the two second fixing rings. At this time, the two second fixing rings are pushed under the elastic force of the second spring, so that the second fixing ring close to the acrylic plate is inserted into the fixing frame, and the acrylic plate is fixed to the door leaf, so that the acrylic plate can be quickly fixed. The acrylic plate can also be quickly disassembled by pulling the second moving rod, the door can be locked by an electric latch, and the door leaf can be automatically closed by a door closer.

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0031] Reference Figure 1-6 The utility model provides an embodiment of a thermal insulation aluminum alloy flat door, comprising a door frame 1, a door leaf 2 is rotatably connected to the left side of the interior of the door frame 1, and mounting grooves 3 are arranged at the upper and lower ends of the interior of the door leaf 2 for installing a shell 21 and a push spring 4, and at the same time, the shell 21 is protected, and multiple push springs 4 are fixedly connected to the opposite sides of the two mounting grooves 3, thereby improving the stability of the installation of the push spring 4, and the other ends of the multiple push springs 4 at the upper and lower ends are arranged with soft rubber strips 5, which are convenient for pushing the soft rubber strips 5 to generate elastic force, thereby filling the gaps generated between the door leaf 2 and the upper and lower ends of the door frame 1, and the opposite sides of the two soft rubber strips 5 are arranged with fixing rods 6, and the outer side of the fixing rod 6 is rotatably connected with a rotating roller 7. When the aluminum alloy door is opened and closed, the rotating roller 7 is rotated by force, which is convenient for the aluminum alloy door to be opened and closed more flexibly, and multiple soft fur pads 8 are arranged on the outer side of the rotating roller 7, which reduces the friction of the rotating roller 7 and is convenient for reducing the noise generated when opening and closing the door.

[0032] The front and rear sides of the door leaf 2 are rotatably connected with a bidirectional screw rod 9, and the middle part of the bidirectional screw rod 9 is fixedly connected with a screw rod 10 to facilitate the rotation of the bidirectional screw rod 9. The middle part of the front and rear sides of the door leaf 2 is rotatably connected with a gear 11, so that the upper and lower ends of the bidirectional screw rod 9 are threadedly connected with a mounting frame 12 for installing a soft brush 15. The inner side of the mounting frame 12 is fixedly connected with a plurality of fixed columns 13 to facilitate the installation of a rebound spring 14 and to facilitate the sliding of a protective shell 16. The other end of the fixed column 13 is fixedly connected with a rebound spring 14, and the other end of the plurality of rebound springs 14 is fixedly connected with a soft brush 15 to increase the elastic force of the soft brush 15, so that the soft brush 15 and the door leaf 2 are more closely fitted. The outer side of the fixed column 13 is slidably connected with a protective shell 16 to facilitate sliding according to the contraction of the rebound spring 14. The inner side of the protective shell 16 is arranged on the outer side of the rebound spring 14 to enhance the protection of the rebound spring 14 and reduce the deformation of the rebound spring 14 when used. A protective frame 18 is fixedly connected to the middle part of the rear two sides to protect the gear 11 and the screw 10. A rotating handle 17 is fixedly connected to the middle part of the opposite side of the two gears 11 to facilitate the rotation of the gear 11. The middle part of the rotating handle 17 is rotatably connected to the middle part of the protective frame 18. The screw 10 and the gear 11 are meshingly connected. The rotation of the gear 11 drives the rotation of the screw 10, thereby driving the rotation of the bidirectional lead screw 9. Two protective rubber strips 19 are arranged on the right side of the door leaf 2 to protect it and reduce the gap between the door frame 1 and the right side of the door leaf 2. Door handles 20 are arranged on the right sides of the front and rear ends of the door leaf 2. Multiple outer shells 21 are fixedly connected to the opposite sides of the two mounting grooves 3. The inner side of the outer shell 21 is slidably connected to the inner shell 22, which prevents the push spring 4 from deformation and prolongs the service life of the push spring 4. The opposite sides of the multiple inner shells 22 at the upper and lower ends are arranged on the opposite sides of the soft rubber strips 5 at the upper and lower ends, thereby improving the stability of the inner shell 22.

[0033] Working principle: When closing the aluminum alloy swing door, pull the door handle 20 to drive the door leaf 2 to rotate on the inner side of the door frame 1, so that the door leaf 2 is pushed to the fixed rod 6 under the push of the spring 4 on the soft rubber strip 5. Due to the movement of the door leaf 2, the rotating roller 7 drives the soft fur pad 8 to roll on the ground. When closing the door frame 1, the spring 4 pushes the soft rubber strip 5 to transfer the driving force to the rotating roller 7, so that the rotating roller 7 drives multiple soft fur pads 8 to press against the door frame 1, thereby reducing the indoor temperature from being lost through the gaps and the outside temperature from penetrating into the room through the gaps, thereby enhancing the thermal insulation performance of the aluminum alloy door. When the aluminum alloy door is exposed to the air for a long time and causes a lot of dust, turn the rotating handle 17, the rotating handle 1 7 drives the gear 11 to rotate, so that the gear 11 meshes with the screw 10, drives the screw 10 to rotate, and the screw 10 drives the bidirectional screw 9 to rotate, so that the bidirectional screw 9 drives the installation frames 12 at the upper and lower ends to move closer to or away from each other, and when the installation frame 12 moves, it drives the soft brush 15 to brush the surface of the door leaf 2, and when the soft brush 15 brushes, the rebound spring 14 pushes the soft brush 15, so that the soft brush 15 and the surface of the door leaf 2 fit more closely, thereby enhancing the cleaning effect, reducing the corrosion of the door leaf 2 caused by the aluminum alloy door being exposed to the air for a long time and being adhered and eroded by dust and impurities, reducing the possibility of damage to the aluminum alloy door, extending the service life of the aluminum alloy door, and facilitating use.
