Description

Technical Field

[0001] This utility model relates to the field of aluminum alloy door and window structure technology, and in particular to a windproof aluminum alloy door and window. Background Technology

[0002] Top-hung windows are a common type of aluminum alloy window. The window sash is hinged to the upper part of the window frame. Pushing the sash outwards causes it to tilt upwards at a certain angle, creating a ventilation opening that allows air to circulate between the inside and outside, thus providing ventilation. Due to its unique opening mechanism, when open, the top-hung window tilts upwards, allowing rainwater to flow out along the tilted surface of the window, thereby keeping the interior dry.

[0003] Patent No. ZL 202420613136.9 discloses a windproof support structure for doors and windows. Through the cooperation of components such as a fixing block, fixing rod, baffle, and limiting rod, the window can be automatically fixed when opened, improving convenience when using the window. However, the solution mentioned in the patent requires manually pulling down the fixing block to move the second sliding rod and connecting rod, thereby pushing the window frame to open, and then using the limiting rod for fixation. Since the window frame itself is quite heavy, pulling down the fixing block requires considerable force, making the operation inconvenient. Furthermore, the limiting rod structure is flimsy and easily damaged under high wind pressure, posing a safety hazard. Summary of the Invention

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a windproof aluminum alloy door and window.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

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.

[0020] Reference Figure 1-4 One embodiment provided by this utility model:

[0021] A windproof aluminum alloy door and window includes a window frame 1, a window sash 2 rotatably connected to the upper part of the window frame 1, a drive mechanism disposed inside the window frame 1, and a support mechanism disposed inside the window frame 1. The drive mechanism is connected to the window sash 2 through the support mechanism. The drive mechanism includes a rotating shaft 3 horizontally disposed at the lower part of the window frame 1, a lead screw 4 vertically disposed on the left and right sides of the window frame 1, and a motor 5 rotatably connected to the rotating shaft 3. A gear set is transmitted between the rotating shaft 3 and the lead screw 4. A transmission block 6 is sleeved on the outside of the lead screw 4. The transmission block 6 is transmittedly connected to the lead screw 4. One end of the support mechanism is connected to the transmission block 6, and the other end of the support mechanism is connected to the lower part of the window sash 2.

[0022] Window frame 1 is vertically positioned and has a frame-like structure. The inner side of window frame 1 is hollow to accommodate window sash 2. Window sash 2 is installed relative to the inner side of window frame 1 and is rotatably connected to the upper part of window frame 1. When window sash 2 is pushed outward, it rotates relative to window frame 1, causing window sash 2 to flip upward, thus opening the window. The drive mechanism is located inside window frame 1 and is driven by motor 5. The support mechanism is located inside window frame 1 and uses a linkage structure. The drive mechanism is connected to window sash 2 through the support mechanism. One end of the support mechanism is connected to the drive mechanism, and the other end is connected to window sash 2. Under the action of the drive mechanism, the support mechanism transmits force, thereby pushing window sash 2 to flip upward.

[0023] The rotating shaft 3 is located inside the window frame 1, horizontally positioned, and rotatably connected to the motor 5. Two lead screws 4 are located inside the window frame 1, vertically positioned, and installed relative to the left and right sides of the window frame 1. A gear set, consisting of several gears, is located between the rotating shaft 3 and the lead screws 4. The rotating shaft 3 is connected to the lead screws 4 via the gear set, thus driving the two lead screws 4 to rotate synchronously on the same rotating shaft 3. A transmission block 6 is sleeved on the outside of the lead screw 4, corresponding one-to-one with each lead screw 4, and the transmission blocks 6 on the two lead screws 4 are horizontally aligned. The transmission block 6 has threads that match the lead screw 4, and is rotatably connected to the lead screw 4, driving the transmission block 6 to move up and down through the rotation of the lead screw 4. One end of the support mechanism is connected to the transmission block 6, and the other end is connected to the lower part of the window sash 2. When the window is closed, the transmission block 6 is located above the lead screw 4, and the support mechanism is set at an angle. When the window needs to be opened, the motor 5 drives the rotating shaft 3 to rotate, and the rotating shaft 3 drives the lead screw 4 to rotate through the gear set. The lead screw 4 drives the transmission block 6 to move downward. One end of the support mechanism moves downward with the transmission block 6 and maintains vertical movement under the constraint of the transmission block 6. The other end of the support mechanism swings around the lower part of the window sash 2 and pushes the lower part of the window sash 2 forward. The support mechanism is equivalent to a crowbar, transmitting the force of the drive mechanism. After the window is opened to a certain angle, the motor 5 is turned off. The transmission method between the lead screw 4 and the transmission block 6 can play a self-locking role.

[0024] This utility model, by setting up a drive mechanism and a support mechanism, allows the motor 5 to be started when the window needs to be opened. The motor 5 drives the rotating shaft 3 to rotate, and the rotating shaft 3 drives the lead screw 4 to rotate through the gear set. The lead screw 4 is connected to the transmission block 6, thereby driving the transmission block 6 to move downward. The transmission block 6 drives one end of the support mechanism to move downward, and the other end of the support mechanism pushes the lower part of the window sash 2 to move forward, so that the window sash 2 flips upward relative to the window frame 1, thereby achieving the effect of electric window opening. The operation is more convenient, and this transmission method has a self-locking function, which can withstand large wind pressure and is not prone to damage.

[0025] In this embodiment, preferably, the gear set includes a driving gear 7 sleeved on the left and right ends of the rotating shaft 3, and a driven gear 8 sleeved on the bottom of the lead screw 4. The driving gear 7 and the driven gear 8 are matched and connected to the driven gear 8 in a transmission manner.

[0026] The driving gear 7 is located at both ends of the rotating shaft 3, sleeved on the outside of the rotating shaft 3, and coaxially connected with the rotating shaft 3. The driven gear 8 is located at the bottom of the lead screw 4, sleeved on the outside of the lead screw 4, and coaxially connected with the lead screw 4. The driving gear 7 and the driven gear 8 are matched and corresponding in position. The driving gear 7 and the driven gear 8 are bevel gear structures, and they mesh with each other for transmission connection. After the motor 5 is started, the motor 5 drives the rotating shaft 3 to rotate, the rotating shaft 3 drives the driving gear 7 to rotate, the driving gear 7 meshes with the driven gear 8, and then drives the driven gear 8 to connect, the driven gear 8 drives the lead screw 4 to rotate, and the lead screw 4 drives the transmission block 6 to move vertically up and down.

[0027] In this embodiment, preferably, the support mechanism includes a main connecting rod 9 rotatably connected to the transmission block 6, and a secondary connecting rod 10 rotatably connected to the lower part of the window sash 2. A coupling 11 is rotatably connected between the main connecting rod 9 and the secondary connecting rod 10. A vertically arranged limiting groove 12 is provided on the inner side of the window frame 1, and one end of the coupling 11 is slidably connected in the limiting groove 12.

[0028] The main connecting rod 9 and the auxiliary connecting rod 10 are positioned relative to the inner side of the window frame 1. The top end of the main connecting rod 9 is rotatably connected to the transmission block 6, and the bottom end of the auxiliary connecting rod 10 is rotatably connected to the lower part of the window sash 2. A coupling 11 is located between the main connecting rod 9 and the auxiliary connecting rod 10. The bottom end of the main connecting rod 9 and the top end of the auxiliary connecting rod 10 each have through holes. The coupling 11 is horizontally inserted into the through holes, with one end extending outward through the through holes. The main connecting rod 9 is rotatably connected to the auxiliary connecting rod 10 via the coupling 11. A limiting groove 12 is formed inside the window frame 1 and extends vertically. The end of the coupling 11 extends into the limiting groove 12 and is slidably connected to it. The limiting groove 12 limits the coupling 11, thereby restricting the main connecting rod 9 from moving vertically. After starting the motor 5, the lead screw 4 drives the transmission block 6 to move downward, thereby causing the main connecting rod 9 to move downward. The main connecting rod 9 and the auxiliary connecting rod 10 rotate relative to each other, thus driving the auxiliary connecting rod 10 to move forward. By adopting the linkage structure described above, compared with the conventional single linkage, the movement stroke of the transmission block 6 can be shortened, the opening and closing time of the window can be reduced, and the driving force of the motor 5 can be saved.

[0029] In this embodiment, preferably, a cable 13 is provided between the transmission block 6 and the window sash 2. The cable 13 is provided on the left and right sides of the window sash 2. One end of the cable 13 is connected to the transmission block 6, and the other end of the cable 13 passes into the interior of the window sash 2 and is connected to the lower part of the window sash 2.

[0030] The cable 13 is located between the transmission block 6 and the window sash 2, positioned relative to the left and right sides of the window sash 2, corresponding to the position of the transmission block 6. One end of the cable 13 is connected to the transmission block 6. The window sash 2 has a groove for the cable 13 to pass through, and the other end of the cable 13 extends into the window sash 2 through the groove and connects to the lower part of the window sash 2. After the motor 5 is started, the transmission block 6 drives one end of the support mechanism to move downward, and the other end of the support mechanism pushes the lower part of the window sash 2 forward, causing the window sash 2 to flip upward relative to the window frame 1. During this process, while the transmission block 6 moves downward, it also drives one end of the cable 13 to move downward, and the other end of the cable 13 tightens the lower part of the window sash 2. In the event of a fall, the cable 13 provides anti-detachment protection.

[0031] In this embodiment, preferably, the window sash 2 is provided with a vertically arranged sliding groove, and a fastening block 14 is slidably connected inside the sliding groove. The cable 13 is connected to the fastening block 14, and a spring is sleeved on the outside. The spring is located between the fastening block 14 and the sliding groove.

[0032] The sliding track is located inside the window sash 2 and is vertically positioned. It can be that the wire groove is positioned relative to the upper middle part of the window sash 2, and the sliding track is positioned relative to the lower part of the window sash 2, with the wire groove and the sliding track interconnected. The fastening block 14 is installed inside the sliding track and slidably connected to it. One end of the cable 13 is connected to the transmission block 6, and the other end of the cable 13 passes through the wire groove and connects to the fastening block 14 inside the sliding track. A spring is located between the fastening block 14 and the sliding track, sleeved on the outside of the cable 13. One end of the spring abuts against the fastening block 14, and the other end abuts against the sliding track. After starting the motor 5, the transmission block 6 drives one end of the cable 13 downwards, pulling the other end of the cable 13 to tighten the fastening block 14. The fastening block 14 slides upwards along the sliding track, compressing the spring, thus tightening the cable 13. Conversely, when the window is closed, the spring is relaxed and pushes the fastening block 14 downwards through spring force, thus tightening the cable 13. In this way, the cable 13 can be kept taut whether the window is open or closed, and the spring can be used for cushioning. Compared with conventional anti-slip ropes, it can offset the impact force on the cable 13 when the window sash 2 falls, and the anti-slip protection effect is stronger.

[0033] In this embodiment, preferably, the upper part of the window sash 2 is provided with a pulley group 15 that matches the cable 13. The pulley group 15 corresponds to the position of the transmission block 6. The cable 13 is arranged around the outside of the pulley group 15 and is slidably connected to the pulley group 15.

[0034] The pulley assembly 15 is located on the upper part of the window sash 2 and is matched with the cable 13. The pulley assembly 15 corresponds to the position of the transmission block 6. The pulley assembly 15 may include two pulleys, one of which corresponds to the outlet position of the wire groove, and the other pulley is vertically aligned with the transmission block 6. The cable 13 is arranged around the outside of the pulley assembly 15 and is slidably connected to the pulley assembly 15. When the transmission block 6 drives the cable 13 to move, the pulley assembly 15 can improve the smoothness of the movement of the cable 13.

[0035] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
