Description

Technical Field

[0001] This utility model relates to the field of system doors and windows technology, specifically to an aluminum alloy system door and window. Background Technology

[0002] Aluminum alloy system windows and doors are a high-performance building window and door solution based on standardized and integrated design concepts. Its core lies in achieving sealing, heat insulation, sound insulation and durability far exceeding traditional windows and doors through scientific structural design, high-quality profiles and accessories, and rigorous performance verification, while using high-precision aluminum alloy profiles.

[0003] In the prior art, an aluminum alloy system door and window disclosed in patent publication number "CN219932026U" relates to the field of aluminum alloy door and window technology. This utility model includes a door and window body, with glass fixedly connected to the center of the body. A second sliding groove is formed at the top front of the glass, and a first sliding groove is formed at the bottom front of the glass. In this utility model, by operating a first motor in the cleaning mechanism, and through the cooperation of various devices within the cleaning mechanism, a cleaning sponge fixedly connected to a moving plate is driven to move towards each other, thereby cleaning the glass. When cleaning is not required, the cleaning sponge is moved to storage slots on both sides via a double-headed screw and the moving plate, thus extending the service life of the cleaning sponge. This solves the problem of residents finding it inconvenient to clean the exterior of the glass, further improving the practicality of the device.

[0004] However, existing technologies still have significant shortcomings. Traditional system windows and doors typically have screens and protective films that operate independently, requiring users to operate them separately. This is not only inconvenient to use but also increases structural complexity. The installation of traditional window and door frames usually relies on screw fixing or welding, which is not only time-consuming and labor-intensive but also prone to loosening after long-term use, affecting sealing and stability. Utility Model Content

[0005] The purpose of this utility model is to provide an aluminum alloy system door and window to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an aluminum alloy system door and window, including a door and window frame, the door and window frame including uprights and horizontal frames, a winding rod installed inside the uprights, a screen and a protective film respectively wound on the surfaces of the two winding rods, the screen and the protective film being staggered front and back, a roller shutter slat is provided at the top of the winding rod, the roller shutter slat is spiral-shaped, a push-pull connecting rod is provided between the two uprights, an elastic lever is fixed at the center of the front of the push-pull connecting rod, and an assembly groove and an arc groove are respectively opened on the top and bottom surfaces of the uprights.

[0007] As can be seen, the above technical solution adopts a linkage design of roller shutter and winding rod, so that the screen and protective film form an integrated linkage mechanism. The screen and protective film are staggered in front and behind, which can effectively avoid the problem of mutual interference between the two. The movement of the push-pull linkage can realize the switching between the protective film and the screen.

[0008] Preferably, the uprights are located between the horizontal frames, and the uprights and the horizontal frames are installed perpendicularly, with the connecting surfaces of the horizontal frames and the uprights fitting together.

[0009] As can be seen, in the above technical solution, the top and bottom surfaces of the horizontal frame and the column fit together, and the adjacent surfaces of the two fit together to achieve seamless installation.

[0010] Preferably, a hanging ring is threadedly connected to the front interface of the push-pull linkage, and hooks are provided on the front of both the screen and the protective film, with the hooks and the connecting ends of the hanging rings cooperating with each other.

[0011] As can be seen, in the above technical solution, the screen and protective film can be connected to the hanging ring on the push-pull linkage through elastic hooks, and can be used simultaneously or separately according to the user's needs.

[0012] Preferably, one side of the cross frame is provided with a push-pull groove, and the push-pull ends at both ends of the push-pull connecting rod are located inside the push-pull groove, and the two are slidably connected.

[0013] As can be seen, in the above technical solution, the push-pull groove can limit the sliding of the push-pull linkage so that it slides linearly between the two horizontal frames.

[0014] Preferably, the assembly slot is located between two arc-shaped slots, and the assembly slot has an array of slots inside, with a limit frame fixed on one side at both ends of the horizontal frame.

[0015] As can be seen, in the above technical solution, the card slot is located in the assembly slot, and the arc-shaped slot is also located on the column for waiting to be assembled with the horizontal frame.

[0016] Preferably, the limiting frame is U-shaped and slidably connected to the assembly groove. One side of the limiting frame has a series of locking blocks, and the locking blocks and the slot cooperate with each other.

[0017] As can be seen, in the above technical solution, the locking block on the limiting frame cooperates with the arc-shaped locking groove of the column assembly slot. After insertion, the locking block automatically locks in place, ensuring that the horizontal frame and the column are tightly connected, thus achieving rapid splicing.

[0018] Preferably, a clamping piece is provided near the limiting frame, and the clamping piece is located inside the arc-shaped groove, with the clamping end of the clamping piece located at the corner of the arc-shaped groove.

[0019] As can be seen, in the above technical solution, the elastic clip of the horizontal frame is inserted into the arc-shaped groove of the column. After the clip is deformed by force, it returns to its original position, forming a self-locking effect, and the fixation can be completed without additional tools.

[0020] Compared with the prior art, the beneficial effects of this utility model are:

[0021] 1. The system employs a linkage design between the roller shutter slats and the winding rod, creating an integrated linkage mechanism between the screen and the protective film. The screen and protective film are staggered to effectively prevent interference. When the user pulls the push-pull lever to unfold the screen, the winding rod tightens the roller shutter slats, while the roller shutter slats on the other side release, causing the protective film to automatically retract. Conversely, when the screen retracts, the protective film automatically unfolds, enabling switching between the protective film and the screen. Users only need to manually control the position of the push-pull lever. Furthermore, the system is connected via elastic hooks, allowing users to choose between linkage or individual use as needed, reducing operational steps and significantly improving efficiency. The protective mode switching effectively prevents accidents caused by the window remaining open after the screen has been retracted.

[0022] 2. The design incorporates arc-shaped grooves, elastic clips, and slots to achieve rapid assembly and high-strength connections. During installation, the elastic clips of the horizontal frame are inserted into the arc-shaped grooves of the uprights. After deformation under force, the clips return to their original position, creating a self-locking effect. Fixing can be completed without additional tools. At the same time, the locking blocks on the limiting frame cooperate with the arc-shaped slots of the upright assembly grooves. After insertion, the locking blocks automatically lock in place, ensuring a tight connection between the horizontal frame and the uprights. This enables rapid assembly, reduces production and installation costs, and improves the reliability and durability of the overall structure. Attached Figure Description

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Please see Figure 1-7 This utility model provides a technical solution:

[0033] Example 1: An aluminum alloy system door and window: including a door and window frame 1, the door and window frame 1 including columns 11 and horizontal frames 12, a winding rod 2 is installed inside the column 11, and a screen 22 and a protective film 23 are respectively wound on the surface of the two winding rods 2, and the screen 22 and the protective film 23 are staggered front and back, and a roller shutter 21 is provided at the top of the winding rod 2, and the roller shutter 21 is spiral-shaped. The outer connecting end of the roller shutter 21 should be fixed to a static bracket or end seat on the inner wall of the column 11. After the outer end is fixed, it forms a fulcrum to ensure that the roller shutter 21 can stably store or release energy when the winding rod 2 rotates. The connecting end at the center of the roller shutter 21 is rigidly fixed to the axis or top surface of the winding rod 2. When the screen 22 is pulled, the rotating winding rod 2 directly twists the roller shutter 21, causing it to store energy and roll up tightly. When released, the roller shutter 21 releases its elasticity, driving the winding rod 2 to reverse, thus automatically retracting the screen 22. A push-pull connecting rod 24 is provided between the two uprights 11. The winding rod 2 is installed inside both uprights 11, and the winding rod 2 can rotate within the uprights 11. The screen 22 and protective film 23 are respectively wrapped around the two winding rods 2. The screen 22 is mainly used to prevent mosquitoes from entering when the doors and windows are ventilated, while the protective film 23 is mainly used to prevent objects from falling and causing accidents when the window glass or screen 22 is not closed. The two are distributed alternately, and one end is simultaneously connected to the push-pull rod. The connecting rod 24 is used to slide the push-pull connecting rod 24 between the two horizontal frames 12, which allows the winding rod 2 to rotate. The automatic winding function of the winding rod 2 mainly relies on the elastic energy storage and release of the roller shutter 21. The roller shutter 21 is equivalent to a torsion spring energy storage structure. Combined with the rotating shaft and guide structure, it realizes the unfolding and retraction of the screen window 22. When the user pulls the screen window 22 horizontally, the screen window 22 fabric unfolds from the rotating shaft surface, which at the same time drives the winding rod 2 to rotate. The roller shutter 21 inside the winding rod 2 is forced to tighten due to the rotation, storing elastic potential energy. When the user releases the handle, the elastic potential energy of the roller shutter 21 is released, driving the winding rod 2 to rotate in the opposite direction. The screen window 22 fabric automatically rolls back under the action of the rotating shaft. The screen 22 and protective film 23 are then restored to their initial storage state. Similarly, the screen 22 and protective film 23 are wrapped around their respective winding rods 2. When the user pulls the push-pull linkage 24 to unfold the screen 22, the winding rod 2 causes the roller shutter 21 to tighten, while the roller shutter 21 on the other side releases, causing the protective film 23 to automatically roll up. Conversely, when the screen 22 is retracted, the protective film 23 automatically unfolds, realizing the switching between the use of the protective film and the screen 22. The protective film 23 is a polycarbonate PC film with a light transmittance of up to 90%, close to the clarity of glass. Its impact resistance is 200 times that of ordinary glass, which can effectively prevent falling or accidental impact. It can be rolled up and retracted, making it suitable for high-rise residential buildings or children's activity areas where fall prevention is required.

[0034] A sliding groove 28 is provided on one side of the horizontal frame 12, and the sliding ends of both ends of the sliding rod 24 are located inside the sliding groove 28 and are slidably connected. A hanging ring 26 is threadedly connected to the front interface of the sliding rod 24. Hooks 25 are provided on the front of both the screen 22 and the protective film 23, and the connecting ends of the hooks 25 and the hanging rings 26 cooperate with each other. The sliding parts at both ends of the sliding rod 24 cooperate with the sliding groove 28 on the horizontal frame 12 to limit the movement, allowing the sliding rod 24 to slide linearly along the sliding groove 28. Since both the screen 22 and the protective film 23 are equipped with hooks 25, and the hooks 25 are connected by springs, the user can quickly connect the screen 22 and the protective film 23 to the same sliding rod 24 by connecting the hooks 25 to the hanging rings 26 on the front of the sliding rod 24. The screen 22 or the protective film 23 can be used alone, or they can be used simultaneously or not, making installation simple.

[0035] A flexible lever 27 is fixed at the center of the front of the push-pull linkage 24. The flexible lever 27 can be deformed at one end by the user pressing it. When the push-pull linkage 24 moves the screen window 22 or protective film 23 to one end, the user can hold the flexible lever 27 to complete the operation. At the same time, pressing the flexible lever 27 will allow it to fit into the opening on the side of the column 11. The fitted flexible lever 27 will return to its shape, so that one end abuts against the inner wall of the opening on the side of the column 11, thereby fixing the position of the push-pull linkage 24. Similarly, when sliding out, simply push it with force to make the flexible lever 27 slide out from the opening.

[0036] Example 2:

[0037] Based on Embodiment 1, the upright 11 is located between the horizontal frames 12, and the upright 11 and the horizontal frame 12 are installed vertically. The connecting surfaces of the horizontal frame 12 and the upright 11 are in close contact with each other. The top and bottom surfaces of the upright 11 are respectively provided with an assembly groove 7 and an arc-shaped groove 8. The assembly groove 7 is located between the two arc-shaped grooves 8. The assembly groove 7 has slots 6 arranged in an array inside. A limiting frame 4 is fixed at one end of both ends of the horizontal frame 12. The limiting frame 4 is U-shaped and is slidably connected to the assembly groove 7. One end of the limiting frame 4... The array has locking blocks 5, which cooperate with the locking slots 6. A clamping piece 3 is located near the limiting frame 4, inside the arc-shaped groove 8, with its clamping end at the corner of the arc-shaped groove 8. The door and window frame 1 is the frame of the system door and window, consisting of uprights 11 and horizontal frames 12. Arc-shaped grooves 8 and assembly grooves 7 are respectively opened at both ends of the uprights 11. Multiple locking slots 6 are arrayed in the assembly grooves 7. The horizontal frames 12 are located at both ends of the uprights 11 for installation. First, align and insert the clip 3 and limiting frame 4 at the horizontal frame 12 with the arc-shaped groove 8 and assembly groove 7. Similarly, install the other column 11 in the same way. The arc-shaped groove 8 has a U-shaped cross-section and the two arc-shaped grooves 8 are not interconnected. It is used to guide and accommodate the insertion of the elastic clip 3. The clip 3 is a metal or high-strength plastic sheet fixed to the end of the horizontal frame 12. It has elastic deformation capability and a beveled end design to facilitate adaptive adjustment during insertion. When the horizontal frame 12 is pushed into the column 11, the beveled end of the clip 3... When in contact with the arc-shaped groove 8, the clamp 3 is squeezed and then bends inward elastically, producing a temporary deformation. The elastic force of the clamp 3 makes it slide tightly against the inner wall of the arc-shaped groove 8, forming an interference fit to ensure a smooth insertion process without loosening. When the horizontal frame 12 is fully inserted, the clamp 3 reaches the preset locking position of the arc-shaped groove 8. Due to the elastic restoring force, the clamp 3 unfolds outward and forms a two-way locking with the arc-shaped groove 8. At this time, the contact surface between the clamp 3 and the arc-shaped groove 8 generates friction and radial pressure, preventing the horizontal frame 12 from shifting laterally or coming out.

[0038] The assembly slot 7 has an array of slots 6 inside. The slots 6 are arc-shaped, like waves. The inner side of the limiting frame 4 has a protruding block 5, which is usually made of plastic. The block 5 of the limiting frame 4 is pre-aligned with the slot 6 of the assembly slot 7. The horizontal frame 12 is pushed along the axis of the column 11. The material of the block 5 must be elastic. After the inclined surface of the block 5 contacts the edge of the slot 6, it is squeezed and shrinks inward. When the limiting frame 4 is fully inserted into the assembly slot 7, the block 5 reaches the corresponding position of the slot 6. The elastic restoring force makes it pop out and embed into the slot 6. The block 5 and the slot 6 form an interlock. The lateral tension must overcome the deformation of the block 5 to separate them, achieving the effect of easy insertion and difficult separation, thus improving the connection strength.

[0039] Working principle: The upright column 11 and the horizontal frame 12 are assembled together. The arc-shaped groove 8 on the upright column 11 is used to connect with the elastic clamp 3 of the horizontal frame 12. The clamping end of the elastic clamp 3 is elastic. When the two are initially aligned, the elastic end of the clamp 3 deforms under force when the horizontal frame 12 is inserted from one side. After the assembly is completed, the elastic end of the clamp 3 returns to its original position, tightening the connection between the horizontal frame 12 and the upright column 11. At the same time, the assembly groove 7 on the upright column 11 is engaged. Multiple arc-shaped slots 6 are arranged. When the limiting frame 4 on the horizontal frame 12 is aligned with the assembly slot 7 and inserted, the locking block 5 on the limiting frame 4 protrudes outward due to the cooperation between the locking block 5 and the slot 6. The locking block 5 deforms under force during insertion. After the limiting frame 4 and the assembly slot 7 are inserted, the locking block 5 is located in the slot 6. At this time, the horizontal frame 12 and the column 11 are difficult to separate. The door and window frame 1 is composed of the column 11 and the horizontal frame 12 to form a rectangular door and window. The winding rod 2 inside the column 11 on both sides... The screen 22 and protective film 23 are respectively wrapped around the screen, and both the screen 22 and protective film 23 are connected to the push-pull linkage 24. The screen 22 and protective film 23 are staggered. The roller shutter 21 acts as the energy storage part of the torsion spring. When the push-pull linkage 24 is pushed or pulled to pull out the screen 22, the winding shaft with the screen 22 wrapped around it tightens the connected roller shutter 21. Similarly, the roller shutter 21 with the protective film 23 wrapped around it loosens accordingly, thus realizing the connection between the screen 22 and the protective film 23. The screen 22 and the protective film 23 are integrated into one unit. The screen 22 and the protective film 23 are linked. When the user pulls out the screen 22 for use, the protective film 23 is automatically rolled up by the action of the roller shutter 21. Similarly, when the screen 22 is rolled up, the protective film 23 is pulled out to prevent accidents. The screen 22 and the protective film 23 can be connected to the hanging ring 26 on the push-pull linkage 24 through the elastic hook 25. They can be used simultaneously or separately according to the user's needs.
