Description

Technical Field

[0001] The present invention relates to the technical field of aluminum-based circuit boards, and in particular to a seamlessly welded thermally-insulated aluminum door and window and a seamless welding method thereof. Background Art

[0002] Doors and windows are one of the important external protective structures of a building, which play the functions of sheltering from wind and rain, heat insulation, sound insulation, lighting, ventilation, etc. With the improvement of people's living standards, the requirements for doors and windows in decoration are getting higher and higher. Broken bridge aluminum doors and windows use thermal insulation broken bridge aluminum profiles and hollow glass, which have energy saving, sound insulation, noise prevention, dustproof, waterproof and other functions. The existing broken bridge aluminum doors and windows mostly use seamless welding technology when connecting, and seamless welding usually uses a grinder to grind the solder at the connection.

[0003] The existing seamless welded thermally-insulated aluminum doors and windows have the following shortcomings: 1. When welding the thermally-insulated aluminum doors and windows, manual hand-holding is required to align the doors and windows. The manual operation is intensive, and the thermally-insulated aluminum doors and windows are prone to dislocation and offset during welding, which reduces the anti-deviation and stability of the thermally-insulated aluminum doors and windows. 2. The doors and windows of the prior art have heat insulation and sound insulation properties, but the heat insulation and sound insulation effects are weak, and the hardness of the aluminum alloy plates is weak, and they are prone to breakage or bending. 3. The existing thermally-insulated aluminum doors and windows require additional screens and dustproof nets, and the existing screens and dustproof nets are set as fixed structures, and the dustproof width cannot be adjusted. The convenience of using the dustproof equipment on the thermally-insulated aluminum doors and windows is relatively weak. Therefore, we propose a seamlessly-welded thermally-insulated aluminum door and window and a seamless welding method thereof. Summary of the Invention

[0004] The main purpose of the present invention is to provide a seamless welded thermally-insulated aluminum door and window, which can effectively solve the problem that the thermally-insulated aluminum door and window in the background technology is prone to dislocation and offset during welding, reduces the anti-deflection and stability of the thermally-insulated aluminum door and window welding, and has weak thermal insulation and sound insulation effects. In addition, the hardness of the aluminum alloy plate is weak, and it is easy to break or bend. In addition, the aluminum door and window itself does not have dustproof equipment and needs to be installed with screens separately, which makes it difficult to use.

[0005] To achieve the above object, the technical solution adopted by the present invention is:

[0006] A seamless welded thermally-insulated aluminum door and window comprises a No. 1 window frame, wherein two No. 1 window frames are provided, and the upper and lower parts of the opposite surfaces of the two No. 1 window frames are welded to a No. 2 window frame, the two No. 1 window frames and the two No. 2 window frames are each provided with an installation groove, and the four installation grooves are each fixedly connected with a reinforcement structure, the left and right ends of the two No. 2 window frames are each provided with a T-slot, the upper and lower parts of the opposite surfaces of the two No. 1 window frames are each fixedly connected with an assembly structure, and the four assembly structures are respectively located in the four T-slots, a limiting groove is provided at the rear part of the upper end of the No. 2 window frame located at the lower part, and a dustproof structure is fixedly connected to the left part of the upper end of the No. 2 window frame located at the lower part, and the dustproof structure is located in the limiting groove, and the right end of the No. 1 window frame located on the left part is hinged with a glass door panel.

[0008] Preferably, the reinforcement structure includes an aluminum alloy inner plate, and the interior of the aluminum alloy inner plate is fixedly connected with a chromium plate, a titanium alloy plate, a ceramic fiber plate, an asbestos plate and a nanoporous thermal insulation felt. Since the ceramic fiber plate, the asbestos plate and the nanoporous thermal insulation felt all have thermal insulation and high temperature resistance properties, the thermal insulation and high temperature resistance strength of the broken bridge aluminum doors and windows are increased, and the external temperature is prevented from affecting the internal temperature of the doors and windows. In addition, the asbestos plate and the nanoporous thermal insulation felt can both reduce noise, improve the sound insulation strength of the broken bridge aluminum doors and windows, and increase the practicality of the broken bridge aluminum doors and windows.

Since chromium and titanium alloy materials are light and hard, the aluminum doors and windows can ensure light weight while having high hardness, thereby increasing the stability and hardness of the broken bridge aluminum doors and windows and avoiding the situation where the broken bridge aluminum doors and windows are easily bent or broken.

[0010] Preferably, the assembly structure includes a T-shaped plate, and the left end of the T-shaped plate is fixedly connected to two pentagonal inserts. The T-shaped plate is first inserted into the T-slot, and then the No. 1 window frame is pushed to insert the pentagonal insert into the assembly tube. The assembly tube is also set to a pentagonal structure, so that the broken bridge aluminum doors and windows have assembly performance during welding, increase the stability and anti-deflection of the broken bridge aluminum doors and windows welding, avoid dislocation and offset when the broken bridge aluminum doors and windows are welded and connected, and improve the welding efficiency of the broken bridge aluminum doors and windows.

[0011] Preferably, the four T-shaped plates are respectively located in the four T-shaped slots, the positions of the several pentagonal inserts respectively correspond to the positions of the several assembly tubes, and the pentagonal inserts are inserted into the assembly tubes, so that the stability and accuracy of the door and window welding are enhanced, and then the welding is aligned through welding technology, so that the aluminum doors and windows have double stability when seamlessly welding.

[0012] Preferably, the dust-proof structure includes a foldable dust-proof plate, the lower right part of the foldable dust-proof plate is fixedly connected to the lower middle part of the L-shaped plate, and the L-shaped plate is movably connected to a movable wheel, the L-shaped plate is located in a limiting groove, and the movable wheel is in contact with the lower groove wall of the limiting groove. When the thermally broken aluminum doors and windows are seamlessly welded and used, the foldable dust-proof plate is manually pushed and pulled to adjust the opening width of the foldable dust-proof plate, so that the dust-proof net of the doors and windows has adjustable width, and when the foldable dust-proof plate is pushed and pulled, the L-shaped plate and the movable wheel are both located in the limiting groove, which increases the flexibility of pushing and pulling the dust-proof equipment on the doors and windows and improves the convenience of pushing and pulling the screens.

When the foldable dustproof plate moves to the corresponding opening width, the anti-slip gear ring is rotated to insert the fixing bolt into the corresponding thread groove, so that the stability of the opening width of the foldable dustproof plate is enhanced, the anti-slip gear ring is easy to operate to prevent hand slippage, and the fixing bolt is more stable than the positioning pin.

[0014] A seamless welding method for seamlessly welding thermally-insulated aluminum doors and windows, comprising the following steps:

[0015] S1: When the thermally insulated aluminum doors and windows cannot be welded, you need to first assemble the two No. 1 window frames and the two No. 2 window frames through the assembly structure. During assembly, first insert the T-plate into the T-slot, then push the No. 1 window frame toward the No. 2 window frame, so that the pentagonal insert on the T-plate is inserted into the assembly tube in the T-slot to complete the assembly;

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] 1. In the present invention, an assembly structure is provided, and two pentagonal inserts are provided on the T-shaped plate on the assembly structure. Both pentagonal inserts are provided with a pentagonal structure. When welding the No. 1 window frame and the No. 2 window frame, the T-shaped plate is first inserted into the T-slot, and then the No. 1 window frame is pushed to insert the pentagonal insert into the assembly tube.

Ceramic fiber boards, asbestos boards and nano-microporous thermal insulation felts are provided on the aluminum alloy inner plates. Since ceramic fiber boards, asbestos boards and nano-microporous thermal insulation felts all have thermal insulation and high temperature resistance properties, the thermal insulation and high temperature resistance strength of the broken aluminum doors and windows is increased, and the external temperature is avoided from affecting the internal temperature of the doors and windows. In addition, the asbestos boards and nano-microporous thermal insulation felts can both reduce noise, thereby improving the sound insulation strength of the broken aluminum doors and windows, and increasing the practicality of the broken aluminum doors and windows.

[0021] 3. In the present invention, a dustproof structure is provided, and a movable wheel is connected to the foldable dustproof plate on the dustproof structure through an L-shaped plate. When the thermally-insulated aluminum doors and windows are seamlessly welded and used, the foldable dustproof plate is manually pushed and pulled to adjust the opening width of the foldable dustproof plate, so that the dustproof net of the doors and windows has adjustable width. When the foldable dustproof plate is pushed and pulled, the L-shaped plate and the movable wheel are both located in the limiting groove, which increases the flexibility of pushing and pulling the dustproof equipment on the doors and windows and improves the convenience of pushing and pulling the screen windows. A fixing bolt is connected to the foldable dustproof plate through a fixing plate, and an anti-slip gear ring is connected to the fixing bolt. When the foldable dustproof plate is moved to the corresponding opening width, the anti-slip gear ring is rotated to insert the fixing bolt into the corresponding threaded groove, so that the stability of the opening width of the foldable dustproof plate is enhanced. The anti-slip gear ring is easy to operate to prevent hand slippage, and the fixing bolt is more stable than the positioning pin. BRIEF DESCRIPTION OF THE DRAWINGS
