Description

Technical Field

[0001] This utility model relates to the field of aluminum alloy door technology, and in particular to an aluminum alloy door sealing device. Background Technology

[0002] In the field of modern architecture, aluminum alloy doors are widely used in various architectural spaces, including residential buildings, commercial spaces, and industrial plants. As a key part of the building envelope, the sealing performance of aluminum alloy doors plays a vital role in the overall performance of the building.

[0003] However, existing technologies, such as Chinese Publication No. CN210396574U, disclose an aluminum alloy door and window sealing device, which relates to the field of aluminum alloy door and window technology. It includes a window frame with two windows placed inside, the two windows being staggered. Storage blocks are fixedly installed on the inner walls of both sides of the window frame. This aluminum alloy door and window sealing device, by setting storage blocks, baffles, and partitions, utilizes the telescopic sleeves inside the baffles and the folding parts inside the partitions to seal the contact between the fixed plate and the window, thereby reducing the gap between the window frame and the window, achieving a tight connection. This ensures good safety and sealing after the window contacts the storage block, effectively preventing raindrops and other debris from entering the room through the gaps, solving the problem of external dirt easily seeping into the room.

[0004] The aluminum alloy door sealing device proposed in this utility model achieves the sealing effect of the aluminum alloy door through the telescopic sleeve rod inside the baffle and the folding parts inside the partition. However, during the use of this device, it can be found that the telescopic sleeve rod and spring will be subjected to tensile and compressive forces during the frequent opening and closing of the aluminum alloy door, which is prone to fatigue damage and affects the sealing effect of the device. Furthermore, the folding parts are prone to loosening and breakage at their connection points due to long-term folding and stretching, which affects the service life of the sealing device. Moreover, the internal structure of the storage block set in this device is complex, the installation process is relatively cumbersome, and if the components are damaged in the future, the repair and replacement will be difficult.

[0022] Compared with the prior art, the advantages and positive effects of this utility model are as follows: 1. This utility model adopts a multi-layer sealing structure. The main sealing cavity is composed of a highly elastic sealing strip with an embedded reinforcing fiber mesh, which engages with the door frame to form the first line of solid sealing defense. The elastic gasket in the secondary sealing cavity can undergo elastic deformation, adapting to subtle changes in the gap between the door and the door frame. When subjected to external pressure or vibration, it maintains a sealed state through its own deformation. The dustproof cavity consists of a fine dustproof mesh and elastic dustproof strips, effectively blocking dust from entering and reducing wear on the sealing structure. Simultaneously, the cavities are separated by elastic partitions. The multi-layer structure works synergistically to construct a three-dimensional sealing barrier, greatly enhancing sealing performance and effectively preventing damage to the sealing effect due to external factors, thus ensuring the long-term stable sealing performance of the aluminum alloy door.

[0023] 2. The sub-frame assembly in this utility model uses quick-connect components for detachable connection.

[0027] Please see Figure 1-4 This utility model provides a technical solution: an aluminum alloy door sealing device, characterized in that it includes an inner frame 5, a sub-frame assembly, a sealing assembly 3, and a drainage assembly; To facilitate the installation of the aluminum alloy door, a sub-frame assembly is provided. The sub-frame assembly is located outside the inner frame 5, providing a stable installation base for the aluminum alloy door. The sub-frame assembly consists of two sets of top frames 1 and two sets of side frames 2, which are detachably connected by quick-connect components 4, reducing the installation difficulty of the sub-frame assembly; The quick-connect assembly 4 includes connecting blocks 401 welded to both ends of the top frame 1, with first screw holes 403 on both sides of the side; connecting grooves 402 are welded to both ends of the side frame 2, and two sets of second screw holes 404 are opened on the side.

By simply fixing the limiting nut 406 in the second screw hole 404, and then letting the fixing screw 405 pass through the second screw hole 404 and the first screw hole 403 in sequence, and then fixing it to the limiting nut 406 through the engagement of the threads, a stable connection and convenient disassembly of the top frame 1 and the side frame 2 can be achieved. To improve the sealing effect of the device, a sealing component 3 is installed on the outside of the sub-frame assembly, and a drainage component is set at the bottom of the sub-frame assembly so that water that enters the device in small amounts can be quickly discharged. The quick-connect structure of the sub-frame assembly facilitates the installation, disassembly, and maintenance of the device. At the same time, the inner frame 5, sub-frame assembly, sealing assembly 3, and drainage assembly work together to effectively improve the sealing performance and drainage capacity of the aluminum alloy door.

[0028] like Figure 1-4 As shown, the sealing assembly 3 includes a main sealing cavity 301, a secondary sealing cavity 302, and a dustproof cavity 303; The main sealing cavity 301 is located on the outside of the sub-frame assembly and is made of a high-elasticity sealing strip. The strip has a reinforcing fiber mesh embedded inside, which can be snapped together with the door frame to form the first line of sealing defense. The secondary sealing cavity 302 is located inside the main sealing cavity 301 and is composed of elastic gaskets. It is fixedly connected to the main sealing cavity 301 and the dustproof cavity 303 on both sides, and can produce elastic deformation to further enhance the sealing effect. The dustproof chamber 303 is located inside the secondary sealing chamber 302 and is composed of a fine dustproof net and an elastic dustproof strip. One side is tightly attached to the sub-frame assembly, forming a dustproof space between the chamber and the sub-frame assembly. Furthermore, the main sealing cavity 301, the secondary sealing cavity 302, and the dustproof cavity 303 are separated by an elastic partition 304, which together form a multi-layer sealing barrier, effectively blocking the intrusion of air, moisture, and dust, and significantly improving the sealing and dustproof performance of the aluminum alloy door.

[0029] like Figure 1-4 As shown, in order to enable the device to quickly and effectively drain the water entering the device, avoid water residue from damaging the aluminum alloy door, and ensure the normal use and service life of the aluminum alloy door, the device is equipped with a drainage component. The drainage component is located in the top frame 1 below, and has a drainage cavity 6 inside. Several reinforcing ribs 7 are welded inside the drainage cavity 6 to enhance the structural strength of the drainage cavity 6. An inclined drainage slope 11 is provided at the bottom of the drainage cavity 6, and a sealing block 9 is provided at one end. Several drainage outlets 10 are opened through the bottom of the sealing block 9 to form a drainage channel. The upper part of the drainage component is equipped with a flow guide 8, which can guide the water flow down in a specific direction, and the inside of the drainage cavity 6 is evenly coated with waterproof paint to prevent water leakage.

[0030] Working Principle: This device is an aluminum alloy door sealing device. In use, first remove the two sets of top frames 1 and two sets of side frames 2. Insert the connecting blocks 401 welded to both ends of the top frame 1 into the corresponding connecting grooves 402 welded to both ends of the side frame 2, ensuring precise alignment of the first screw hole 403 on the side of the connecting block 401 with the second screw hole 404 on the side of the connecting groove 402. Next, pass the fixing screw 405 through the second screw hole 404 and the first screw hole 403 in sequence until one end of the screw protrudes. Then, screw the limiting nut 406 onto the protruding end of the screw. By appropriately tightening the limiting nut 406, the top frame 1 and the side frame 2 are securely connected. During the connection process, ensure that the shock-absorbing pad 407 on the inner end face of the connecting groove 402 is in close contact with the connecting block 401 to reduce vibration and wear at the connection point. Next, the sealing component 3 is completely wrapped around the assembled sub-frame component, ensuring that the main sealing cavity 301 is located outside the sub-frame component and that the high-elasticity sealing strip of the main sealing cavity 301 can be engaged with the door frame. The secondary sealing cavity 302 is located inside the main sealing cavity 301 and is fixedly connected to the main sealing cavity 301 and the dustproof cavity 303 by relying on the characteristics of its elastic gasket. At the same time, it ensures that one side of the dustproof cavity 303 is tightly fitted with the sub-frame component to form a dustproof space. The elastic partitions 304 between the cavities act as separators, constructing a complete sealing barrier. Finally, the assembled sub-frame component is fitted over the inner frame 5, so that the inner frame 5 and the sub-frame component form a stable overall structure, completing the assembly of the aluminum alloy door sealing device. Then, the sealing device is initially fixed to the aluminum alloy door by engaging the main sealing cavity 301 with the door frame.
