An aluminum alloy door and window with an adjustable-angle ventilation opening

Abstract

This application belongs to the field of aluminum alloy door and window technology, and discloses an aluminum alloy door and window with an adjustable-angle ventilation opening, including an aluminum alloy frame and door and window components. Two slide rails are welded parallel to each other on the inner side of the aluminum alloy frame, and a door and window component slides on each slide rail. This application adopts a ventilation cover fixed to the back of the aluminum alloy frame with screws. Since several louvers are movably installed in the two rectangular ventilation openings of the ventilation cover, by pushing the door and window components in the aluminum alloy frame, the rollers at the bottom of the door and window components roll along the slide rails. When the two door and window components overlap, by manually moving the louvers of the ventilation cover, the movable columns at both ends of the louvers rotate relative to the inner side of the rectangular ventilation opening, and the rubber blocks on the inner side of the rectangular ventilation opening maintain the louvers to a limit of any angle. While satisfying the requirement of arbitrary adjustment of the door and window ventilation angle, it also has the advantage of dust prevention.

Description

Technical Field

[0001] This application relates to the field of aluminum alloy door and window technology, and more specifically, to an aluminum alloy door and window with an adjustable-angle ventilation opening. Background Technology

[0002] Aluminum alloy doors and windows refer to doors and windows made using extruded aluminum alloy profiles as frames, mullions, and sashes. They are also known simply as aluminum doors and windows. Aluminum alloy doors and windows include those using aluminum alloy as the load-bearing structure (the structural members that bear and transmit their own weight and load) and those made of wood or plastic composites, referred to as aluminum-wood composite doors and windows or aluminum-plastic composite doors and windows. The quality of aluminum alloy doors and windows can be roughly judged from factors such as the selection of raw materials (aluminum profiles), the surface treatment and internal processing quality of the aluminum material, and the price of the doors and windows.

[0003] A search revealed a public (announcement) number: CN220815389U, which describes an aluminum alloy door and window, comprising: an outer frame and two door and window assemblies disposed within the outer frame. The inner wall of the outer frame has a recessed rectangular groove. An inclined guide block with a trapezoidal cross-section is connected to the bottom of the rectangular groove. Two strip support plates are spaced apart on the inclined surface of the inclined guide block. Two rollers are spaced apart on the bottom of each door and window assembly, and the rollers are in rolling contact with the upper surface of the corresponding strip support plate. A rectangular frame plate is connected within the rectangular groove, and a gap exists between the bottom of the rectangular frame plate and the inclined guide block. The device also includes a drainage system to guide rainwater entering the rectangular groove to the outside. This invention has a reasonable structure, allowing rainwater entering the rectangular groove to flow quickly to the outside, preventing rainwater from mixing with small particulate impurities for extended periods and producing unpleasant odors, thus enhancing its performance.

[0004] The above solution avoids the odor problem caused by water accumulation in doors and windows, but it does not include an adjustable ventilation opening angle structure or a corresponding door and window sealing structure. When doors and windows are opened or closed, there are problems with the ventilation angle not being adjustable and poor dust prevention and sealing effects.

[0005] To address the aforementioned issues, this application provides an aluminum alloy door and window with an adjustable-angle ventilation opening. Utility Model Content

[0006] The aluminum alloy door and window with an adjustable angle ventilation opening provided in this application adopts the following technical solution:

[0007] An aluminum alloy door and window with adjustable-angle ventilation openings includes an aluminum alloy frame and door and window components. Two parallel sliding rails are welded to the inner side of the aluminum alloy frame, and a door and window component slides on each rail. A sealing plate is adhered to the inner side of the aluminum alloy frame, and the sealing plate is respectively attached to the two door and window components. A ventilation hood is detachably installed on the back of the aluminum alloy frame, and two rectangular ventilation openings are pre-reserved on the surface of the ventilation hood corresponding to the two door and window components. A set of louvers is installed on each of the two rectangular ventilation openings of the ventilation hood. Movable columns are welded to both ends of the louvers, and the movable columns are inserted into the inner side of the rectangular ventilation openings of the ventilation hood. A rubber block is adhered to the inner side of the rectangular ventilation openings of the ventilation hood, and the rubber block contacts the end face of the louver.

[0008] The above technical solution not only allows for arbitrary adjustment of the ventilation angle of doors and windows, but also has the advantage of dust prevention.

[0009] Furthermore, a sealing groove is provided on the inner side of the aluminum alloy frame, and an irregularly shaped sealing strip is bonded in the sealing groove. The irregularly shaped sealing strip has an overall U-shaped structure, and an arc-shaped structure is provided in the middle of the irregularly shaped sealing strip. A flat sealing strip is embedded in the side of the door and window assembly, and the flat sealing strip is set towards the irregularly shaped sealing strip.

[0010] The above technical solutions ensure that doors and windows are dustproof and airtight.

[0011] Furthermore, two rollers are tumbling on the bottom of the door and window assembly, and the two rollers are connected to the slide rails of the aluminum alloy frame.

[0012] The above technical solution satisfies the sliding function of door and window components.

[0013] Furthermore, mounting blocks are welded to both the left and right sides of the ventilation hood, and the surfaces of the mounting blocks are fixedly connected to the aluminum alloy frame by screws.

[0014] The above technical solution facilitates the installation of ventilation hoods.

[0015] Furthermore, the side of the rubber block facing the movable column has an arc-shaped notch, and the ratio of the number of rubber blocks to louvers is 2:1.

[0016] The above technical solution increases the fit between the rubber block and the movable column.

[0017] Furthermore, the movable column of the louver is a cylindrical structure, and abutment strips are welded to the surface of the louver, with the abutment strips contacting the louver below it.

[0018] The above technical solution maintains the airtightness of multiple louvered panels.

[0019] In summary, this application includes the following beneficial technical effects:

[0020] The ventilation hood is fixed to the back of the aluminum alloy frame with screws. Since several louvers are movably installed in the two rectangular ventilation openings of the ventilation hood, by pushing the door and window components in the aluminum alloy frame, the rollers at the bottom of the door and window components roll along the slide rail. When the two door and window components overlap, by manually moving the louvers of the ventilation hood, the movable columns at both ends of the louvers rotate relative to the inner side of the rectangular ventilation opening. The rubber blocks on the inner side of the rectangular ventilation opening maintain the louvers at any angle. This not only allows for arbitrary adjustment of the door and window ventilation angle, but also has the advantage of dust prevention.

[0021] The system employs flat sealing strips embedded on both sides of the door and window components. As the door and window components move, they adhere closely to the inner wall of the aluminum alloy frame. The sealing grooves on the inner wall of the aluminum alloy frame come into contact with the flat sealing strips of the door and window components through the irregularly shaped sealing strips. As the door and window components continue to move forward, they compress the irregularly shaped sealing strips. Because the irregularly shaped sealing strips have an overall U-shaped structure and an arc-shaped structure in the middle, the arc-shaped structure of the irregularly shaped sealing strips tends to flatten under the pressure of the door and window components. As a result, the ends of the irregularly shaped sealing strips shrink and deform, wrapping around the sides of the door and window components. Combined with the sealing plate set between the two door and window components, the overall sealing performance can be greatly improved, providing both dustproof and sealing effects.

[0031] Example:

[0032] This application discloses an aluminum alloy door and window with an adjustable-angle ventilation opening. Please refer to [link / reference]. Figure 1 and Figure 4 The system includes an aluminum alloy frame 1 and door / window components 3. Two parallel sliding rails 2 are welded to the inner side of the aluminum alloy frame 1, and a door / window component 3 slides on each sliding rail 2. A sealing plate 5 is bonded to the inner side of the aluminum alloy frame 1, and the sealing plate 5 is respectively attached to the two door / window components 3. A ventilation hood 4 is detachably installed on the back of the aluminum alloy frame 1, and the surface of the ventilation hood 4 has two rectangular ventilation openings corresponding to the two door / window components 3. A set of louvers 6 is installed on each of the two rectangular ventilation openings of the ventilation hood 4. Movable columns 10 are welded to both ends of the louvers 6, and the movable columns 10 are inserted into the inner side of the rectangular ventilation openings of the ventilation hood 4. A rubber block 11 is bonded to the inner side of the rectangular ventilation openings of the ventilation hood 4, and the rubber block 11 is in contact with the end face of the louver 6. The two rectangular ventilation openings of the ventilation hood 4 are respectively set towards the two door / window components 3, which can realize targeted ventilation at the two door / window components 3. The sealing plate 5 is composed of a honeycomb panel and sound-absorbing cotton bonded to both sides, which is beneficial for dust prevention and sealing, and also easy to reduce noise.

[0033] Please see Figure 2 A sealing groove 7 is provided on the inner side of the aluminum alloy frame 1, and an irregular sealing strip 8 is bonded in the sealing groove 7. The irregular sealing strip 8 has a U-shaped structure and an arched structure in the middle. A flat sealing strip 12 is embedded in the side of the door and window assembly 3 and faces the irregular sealing strip 8. With the above structure, combined with the sealing plate 5 between the two door and window assemblies 3, the overall sealing performance can be greatly improved, and it has the dual effect of dust prevention and sealing.

[0034] Please see Figure 2 and Figure 3 Two rollers 13 are rolled on the bottom of the door and window assembly 3, and the two rollers 13 are connected to the slide rail 2 of the aluminum alloy frame 1. The setting of rollers 13 and slide rail 2 increases the smoothness of sliding of the door and window assembly 3.

[0035] Please see Figure 2 and Figure 3 Mounting blocks 9 are welded to both the left and right sides of the ventilation hood 4, and the surface of the mounting blocks 9 is fixedly connected to the aluminum alloy frame 1 by screws. The mounting blocks 9 facilitate the installation and fixing of the ventilation hood 4. The ventilation hood 4 faces the outside of the aluminum alloy frame 1, which means it is installed facing the outside.

[0036] Please see Figure 2 The rubber block 11 has an arc-shaped notch on the side facing the movable column 10, and the ratio of the number of rubber blocks 11 to louvers 6 is 2:1. Through the setting of rubber blocks 11 and arc-shaped notches, the louvers 6 can be limited and supported at any tilt angle. The limiting principle between the two is mainly achieved through friction. Each louver 6 is equipped with two rubber blocks 11 to satisfy the reliable limiting and support of the louvers 6.

[0037] Please see Figure 2 The movable column 10 of the louvered panel 6 is a cylindrical structure. The surface of the louvered panel 6 is welded with abutment strips, and the abutment strips are in contact with the louvered panel 6 below it. Through the setting of the abutment strips, multiple louvered panels 6 can be combined to form a sealed whole, increasing the dustproof and sealing effect.

[0038] The implementation principle of this embodiment is as follows: During use, by pushing the door and window assembly 3 inside the aluminum alloy frame 1, the rollers 13 at the bottom of the door and window assembly 3 roll along the slide rail 2. When two door and window assemblies 3 overlap, by manually moving the louvers 6 of the ventilation hood 4, the movable columns 10 at both ends of the louvers 6 rotate relative to the inner side of the rectangular ventilation opening. The rubber blocks 11 on the inner side of the rectangular ventilation opening maintain the louvers 6 at any angle, allowing for arbitrary adjustment of the door and window ventilation angle. As the door and window assembly 3 moves, it remains in close contact with the inner wall of the aluminum alloy frame 1. The sealing groove 7 on the inner wall of the aluminum alloy frame 1 comes into contact with the flat sealing strip 12 of the door and window assembly 3 through the irregular sealing strip 8. As the door and window assembly 3 continues to advance, it compresses the irregular sealing strip 8. Since the irregular sealing strip 8 has an overall U-shaped structure and an arc-shaped structure in the middle, the arc-shaped structure of the irregular sealing strip 8 tends to flatten under the pressure of the door and window assembly 3. Then, after the two ends of the irregular sealing strip 8 shrink and deform, it wraps around the side of the door and window assembly 3. Combined with the sealing plate 5 set between the two door and window assemblies 3, the overall sealing performance can be greatly improved.

[0039] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
