Abstract
Description
Technical Field
[0001] This utility model relates to the field of building door and window technology, and in particular to a thermally broken aluminum window frame with an adjustable limiting structure. Background Technology
[0002] With the continuous improvement of building energy conservation and residential safety standards, thermally broken aluminum alloy windows have become the mainstream choice for exterior window systems in modern mid-to-high-end residences, office buildings and public buildings due to their excellent thermal insulation performance, good air tightness and high structural strength. Among them, the system window frame, as the core load-bearing structure of the whole window, integrates functional modules such as profiles, sealing, hardware linkage and limit control. Its design level directly affects the user experience and long-term reliability of the window.
[0003] However, most thermally broken aluminum window systems currently use fixed limiters or mechanical corner brackets to limit the maximum opening angle of the window sash. These limiters are usually set to a fixed angle during the installation phase, and once determined, they cannot be adjusted according to the actual usage scenario. For example, in spring and summer when a large amount of airflow is needed, users find it difficult to increase the opening range; while in winter or windy weather, it is impossible to further reduce the opening angle to reduce heat loss and wind noise interference. More importantly, for families with children, such fixed limiters cannot meet the safety protection needs of different age groups. If the initial setting angle is too large, there is a risk of falling.
[0004] Therefore, it is necessary to design a thermally broken aluminum window frame system with an adjustable limiting structure. Utility Model Content
[0005] In order to overcome the shortcomings of existing thermally broken aluminum windows with fixed limiting angles and inconvenient adjustment, this utility model provides a thermally broken aluminum system window frame with an adjustable limiting structure.
[0006] The technical implementation scheme of this utility model is as follows: a thermally broken aluminum window frame with an adjustable limiting structure, comprising a main window frame, thermal break strips, a window sash, a sliding groove, a slider, a support arm, a connecting pipe, a limiting rod, a splined shaft, and a grille plate. Multiple thermal break strips are embedded inside the main window frame. The window sash is rotatably connected to the front side of the main window frame. Sliding grooves are provided on both the upper and lower sides of the main window frame, and sliders are slidably connected inside each groove. Support arms are rotatably connected to the upper parts of each slider. The side of the support arm furthest from the slider is connected to the side frame of the window sash. A connecting tube is fixedly connected to the slider on the lower side. A limit rod is slidably and rotatably connected to one end of the connecting tube near the window sash. A spline shaft is fixedly connected inside the connecting tube. A slot matching the spline shaft is opened on the limit rod. When the front end of the limit rod is in a vertically downward state, the spline shaft can be inserted into the slot. A grid plate is fixedly connected to the lower part of the main window frame. The grid plate is composed of several parallel strips with equidistant gaps between adjacent strips. The front end of the limit rod is inserted downward into the gap between two adjacent strips.
[0007] Furthermore, it also includes a handle, with a handle fixedly connected to the front side of the window sash, and the gripping part of the handle is covered with a TPE anti-slip layer.
[0008] Furthermore, it also includes cushioning pads, with multiple cushioning pads provided on one side of the window sash near the main window frame.
[0009] Furthermore, it also includes a dustproof net, which is installed on the main window frame and located on the back of the window sash.
[0010] Furthermore, both the main window frame and the window sash are made of aluminum alloy profiles, and the thermal insulation strip is made of nylon.
[0011] Furthermore, the grooved inner wall of the limiting rod and the spline shaft are provided with friction damping to prevent them from accidentally disengaging due to vibration or wind pressure when they are plugged in.
[0012] Beneficial effects: 1. This utility model achieves an adjustable window opening angle by inserting the front end of the limiting rod into the gap between any two adjacent strips in the grille plate, allowing the limiting rod to slide along the gap and tilt under pressure during the window opening process, while maintaining a sliding and rotating connection with the connecting pipe, and in conjunction with the spline shaft connection, thus solving the problem that existing thermally broken aluminum windows cannot be flexibly adjusted according to ventilation needs.
[0013] 2. This utility model sets a friction damping fit between the spline shaft and the slotted limit rod, so that the two have a certain holding force after being inserted. At the same time, when closing the window sash, it is necessary to actively apply force to make the spline shaft disengage, which prevents the limit structure from accidentally disengaging due to vibration or wind pressure, and ensures the stability of the window sash during locking or closing.

Detailed Implementation
[0019] Example: A thermally broken aluminum window frame system with an adjustable limiting structure, such as... Figures 1-4 As shown, the system includes a main window frame 1, thermal break strips 2, a window sash 3, a sliding groove 6, a slider 7, a support arm 8, a connecting pipe 9, a limiting rod 10, a splined shaft 11, and a grille plate 12. Multiple thermal break strips 2 are embedded inside the main window frame 1. The window sash 3 is hinged and rotatably connected to the front of the main window frame 1. Both the main window frame 1 and the window sash 3 are made of aluminum alloy profiles, and the thermal break strips 2 are made of nylon, improving the corrosion resistance and strength of the core structural materials and increasing the service life of the equipment. Sliding grooves 6 are provided on both the upper and lower sides of the main window frame 1. Sliding sliders 7 are slidably connected inside the sliding grooves 6. Support arms 8 are rotatably connected to the upper part of each slider 7. The side of the support arm 8 furthest from the slider 7 is connected to the side frame of the window sash 3. The slider 7 is located on the lower side... A connecting pipe 9 is fixedly connected to the upper part of the window frame 1. A limiting rod 10 is slidably and rotatably connected to one end of the connecting pipe 9 near the window sash 3. A spline shaft 11 is fixedly connected inside the connecting pipe 9. A slot matching the spline shaft 11 is opened on the limiting rod 10. When the front end of the limiting rod 10 is in a vertically downward state, the spline shaft 11 can be inserted into the slot. A grid plate 12 is fixedly connected to the lower part of the main window frame 1. The grid plate 12 is composed of several parallel strips with equidistant gaps between adjacent strips. The front end of the limiting rod 10 is inserted downward into the gap between two adjacent strips. The inner wall of the slot on the limiting rod 10 and the spline shaft 11 are provided with friction damping to prevent them from accidentally disengaging due to vibration or wind pressure when they are connected.
[0020] like Figure 1 and Figure 2As shown, it also includes a handle 4. The handle 4 is fixedly connected to the front side of the window sash 3, and the gripping part of the handle 4 is covered with a TPE anti-slip layer, which is comfortable to grip, anti-slip and wear-resistant, and improves the ease of operation.
[0021] like Figure 2 As shown, it also includes a buffer pad 5. Multiple buffer pads 5 are provided on one side of the window sash 3 near the main window frame 1. When closed, they can reduce vibration and noise, protect the profile, and extend the service life.
[0022] like Figure 1 As shown, it also includes a dustproof net 13. The main window frame 1 is equipped with a dustproof net 13, which is located on the back side of the window sash 3. It can effectively block dust, pollen, and mosquitoes from entering the room, thereby improving indoor air quality and user comfort.
[0023] In actual use of this window frame, in the initial state, the window sash 3 is installed on the front side of the main window frame 1 through a hinge structure, the handle 4 is located in an easy-to-operate position, and the buffer pad 5 is attached to one side of the window sash 3, which can effectively absorb the impact when closing. At this time, the slot on the limiting rod 10 in the connecting tube 9 does not cooperate with the spline shaft 11 inside the connecting tube 9, so the limiting rod 10 can rotate freely at the connection point and can also slide along the axial direction of the connecting tube 9.
[0024] When the user opens the window sash 3 via handle 4, the window sash 3 rotates around the hinge point, causing the upper and lower support arms 8 to move. At the same time, the slider 7 is pushed to slide horizontally along the groove 6 on the main window frame 1. The movement of the slider 7 is also transmitted through the connecting pipe 9, causing the limiting rod 10 to move synchronously. Since the lower front end of the limiting rod 10 is restricted in the fixed gap of the grille plate 12, it is squeezed by the side wall of the strip rod during the movement, and is forced to gradually tilt from the vertical state, presenting a "being dragged" movement. During this process, the window sash 3 can continue to open, and the limiting rod 10 slides along the grille gap with the slider 7, realizing the free adjustment of the opening angle.
[0025] When the user wants to fix the window sash 3 at the current opening angle, force needs to be applied to push the limiting rod 10 to move backward until the slot on it is aligned and completely fitted into the spline shaft 11 inside the connecting tube 9. After the spline shaft 11 is inserted into the slot, the rotational freedom of the limiting rod 10 is restricted, and it becomes a rigid connection state that can only slide axially and cannot rotate. At this time, the lower front end of the limiting rod 10 is still stuck in the gap of the grille plate 12 and cannot move laterally, forming a space lock, which in turn restricts the stroke of the slider 7, so that the slider 7 can no longer slide along the slide groove 6. After the slider 7 is locked, the movement of the support arm 8 is blocked, and the opening angle of the window sash 3 is reliably fixed.
[0026] When closing window sash 3, the user must first apply force to pull the limiting rod 10 forward, causing the spline shaft 11 to disengage from the slot of the limiting rod 10, restoring the rotational freedom of the limiting rod 10. Because the inner wall of the slot on the limiting rod 10 and the spline shaft 11 are fitted with friction damping, accidental disengagement due to vibration or wind pressure during the insertion process is prevented. After regaining its free state, window sash 3 can then be smoothly closed to its initial position. Throughout operation, the dustproof net 13 remains positioned behind window sash 3, blocking external dust, insects, and other contaminants from entering the room, improving user comfort. The TPE anti-slip layer covering the handle 4 enhances the grip, making it less slippery or icy, especially in humid or cold environments. The main window frame 1 and window sash 3 are made of thermally broken aluminum alloy profiles, with an internally embedded nylon thermal insulation strip 2, effectively blocking heat conduction between indoors and outdoors, improving the overall insulation and energy-saving performance of the window.
