Description

Technical Field

[0001] The utility model relates to the field of aluminum alloy doors, in particular to an environment-friendly heat-insulating aluminum alloy door structure. Background Technique

[0002] An aluminum alloy door refers to a door and window made of aluminum alloy extrusion profiles as frames, stiles, and sashes, simply called an aluminum door. Aluminum alloy doors include those with aluminum alloy as the stress member (the member that bears and transmits its own weight and load) and those combined with wood or plastic, simply called aluminum-wood composite doors and aluminum-plastic composite doors. Traditional aluminum alloy doors are composed of components such as aluminum profiles, sealants, and glass. Due to the good thermal conductivity of aluminum, the heat insulation and heat preservation performance of the doors are not good, and they are gradually replaced by new aluminum alloy doors.

[0003] Traditional common aluminum alloy doors generally only have a simple aluminum alloy shell with a foam board filled inside to support, resulting in poor heat insulation of the doors. To solve the above problems, the existing aluminum alloy doors mostly achieve the heat insulation effect of the door body structure by filling an environment-friendly heat-insulating layer and a heat-preserving layer inside the door. However, the materials of the heat-insulating layer and the heat-preserving layer filled inside the existing aluminum alloy doors are mostly directly filled at both sides inside the door body, and are fixed by adhering to the inner wall of the door body, leaving a cavity in the middle as a vacuum chamber to achieve the sound insulation effect. The problems are as follows:

[0004] The layer structures fixed on both sides of the inner wall of the door body lack stability inside the door body. When the door body is subjected to external forces, it is easy to separate from the inner wall of the door body, thereby reducing the heat insulation and heat preservation performance. Moreover, when the middle of the door body is used as a vacuum chamber, it is more difficult to ensure the connection stability between the layer structure and the inner wall of the door body due to the influence of the internal pressure of the door body.

[0005] Therefore, the utility model proposes an environment-friendly heat-insulating aluminum alloy door structure. Content of the Utility Model

Specific implementation mode

[0022] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0023] Please refer to Figures 1-4 , the present invention provides a technical solution for a structure of an environmentally friendly heat-insulating aluminum alloy door: including a door frame 1, an inner partition layer 2 is fixedly connected inside the door frame 1, limit structures 3 are movably arranged at both the upper and lower ends inside the door frame 1, upper sealing cushion plates 4 and upper protection frames 5 are fixedly connected to the upper and lower ends of the door frame 1, a heat-insulating cushion plate 6 and a heat-insulating layer 7 are fixedly connected to one inner wall of the door frame 1, the limit structure 3 is simultaneously located at the vertical end position of the inner partition layer 2, the limit structure 3 includes an adjusting rod 8, a connecting block 9, a guide rod 10 and a limit frame 11, the adjusting rod 8 and the connecting block 9 are movably sleeved, the guide rod 10 movably penetrates through the connecting block 9, the limit frame 11 is rotatably connected to the connecting block 9, and the limit structure 3 further includes a fixedly connected support frame 12 and a fixing plate 13.

[0024] As Figures 1-2 shown, the upper protection frame 5 is integrally arranged in a rectangular frame shape, is buckled at the upper and lower ends of the door frame 1, and is connected to the door frame 1 through an external screw. The upper sealing cushion plate 4 is arranged in a fitting manner on the upper and lower end surfaces of the door frame 1. There are two groups of inner partition layers 2 vertically arranged, which are arranged in a fitting manner on the longitudinal inner wall of the door frame 1. Through the cooperation of the upper protection frame 5 and the upper sealing cushion plate 4, the connection position between the limit structure 3 and the door frame 1 is sealed, and through the inner partition layer 2, the inner partition layer structure inside the door frame 1 is limited.

[0025] After the installation of the heat insulation layer structure inside the door frame 1 is completed, the user can vacuum the cavity formed between the two inner partitions 2 or perform filling operations inside it to ensure that the overall door frame 1 has good sound insulation and heat insulation properties. The upper sealing gasket 4 and the upper protective frame 5 are conducive to ensuring the sealing performance inside the door frame 1.

[0026] As Figure 4 shown, the adjusting rod 8 is set as a threaded rod and is threadedly connected to the door frame 1. At the same time, the adjusting rod 8 is movably penetrated through the door frame 1. The connecting block 9 is longitudinally arranged as a rectangular block and is slidably connected to the inner wall of the door frame 1 through the guide rod 10. The guide rod 10 is longitudinally penetrated through the connecting block 9, and a vertical sliding groove is correspondingly arranged on the inner wall of the door frame 1 for the guide rod 10. The limiting frame 11 is located at both ends of the bottom of the connecting block 9 and is arranged as a rectangular frame. The limiting frame 11 and the connecting block 9 are elastically connected through a shaft body and a torsion spring sleeve. By adjusting the rod 8, the effect of controlling the vertical sliding adjustment of the connecting block 9 inside the door frame 1 is achieved. By the guide rod 10, the effect of ensuring the sliding stability of the connecting block 9 is achieved. By the limiting frame 11, the effect of supporting and limiting the heat insulation layer 7 on both inner walls of the door frame 1 is achieved.

[0027] After the heat insulation layer structure is installed inside the door frame 1, the user rotates the adjusting rod 8. While the adjusting rod 8 descends, it drives the connecting block 9 to descend inside the door frame 1, and then drives the limiting frame 11 to descend and contact the support frame 12, causing the limiting frame 11 to flip upward for adjustment. During the upward flipping process of the limiting frame 11, its outer end contacts the heat insulation layer 7 on both inner walls of the door frame 1 to support and limit it.

[0028] As Figure 4 shown, the support frame 12 is fixedly connected to both ends of the fixing plate 13 and is arranged to slope upward. The longitudinal inner end of the fixing plate 13 is fixedly connected to the longitudinal inner wall of one side of the door frame 1. The support frame 12 and the fixing plate 13 are both located below the limiting structure 3. By the support frame 12, the effect of supporting the limiting frame 11 from the bottom position is achieved.

[0029] During the process of the connecting block 9 descending inside the door frame 1, the limiting frame 11 descends and contacts the support frame 12. The limiting frame 11 is blocked by the support frame 12 and then flips upward for adjustment, thereby realizing the support and limit of the heat insulation layer 7.

[0030] The working principle of the present utility model is as follows: After the heat insulation backing plate 6 and the heat insulation layer 7 are installed on the inner walls on both sides of the door frame 1 by the user, they are lowered through the limiting structure 3, and then a supporting structure for the heat insulation layer structure inside the door frame 1 is formed. Cooperating with the inner partition layer 2 can effectively ensure the installation stability of the heat insulation layer structure inside the door frame 1. After that, the user can perform a vacuum treatment on the chamber formed by the inner partition layer 2, or perform another filling operation at this place. Finally, the user can install and fix the upper sealing backing plate 4 and the upper protection frame 5 at the upper and lower ends of the door frame 1.

[0031] The above is only the preferred embodiment of the present utility model. It should be noted that for those of ordinary skill in the art in this technical field, without departing from the principle of the present utility model, several improvements and refinements can be made, and these improvements and refinements should also be regarded as the protection scope of the present utility model. The structures, devices, and operation methods not specifically described and explained in the present utility model, unless otherwise specified and limited, are implemented according to the conventional means in this field.
