Description

Technical Field

[0001] This utility model relates to the field of aluminum alloy casement window technology, and more specifically to an aluminum alloy casement window with a self-locking function. Background Technology

[0002] Aluminum alloy casement windows are window products that open inwards or outwards and use aluminum alloy profiles as the outer frame and inner frame. They are usually used as ventilation windows in buildings. After closing the aluminum alloy casement window, people lock it to the outer frame to prevent it from opening automatically due to external factors.

[0003] Research indicates that current mainstream aluminum alloy casement windows primarily feature aluminum alloy frames paired with rotatable casement sashes. Some products include screens (fixed or sliding) to block insects. Regarding self-locking functionality, existing technologies mainly employ mechanical lock structures, such as handle-linked latches and multi-point locking systems. Locking is achieved by manually turning the handle to engage the latch with the window frame latch. Some products use magnetic self-locking, utilizing magnetic attraction to keep the window sash stable after closing. Additionally, a few high-end products incorporate electric control components, such as motor-driven latch extension and retraction, but these often require separate control buttons or remote controls. Furthermore, the self-locking structure and screen system are often independently designed, lacking coordination. In terms of security and convenience optimization, current technologies focus on improving the anti-theft performance of the lock (e.g., thickening the latch, adding locking points) or simplifying manual operation. However, there is still room for improvement in automated self-locking, unlocking linkage, and operational efficiency.

[0004] The shortcomings of existing technologies: Traditional mechanical locks require manual rotation of the handle to lock, and some multi-point lock systems even require multiple operations, which is cumbersome; although magnetic self-locking does not require manual operation, the attraction force is limited and it is easy to loosen under wind or slight external impact, making it impossible to achieve stable locking. Moreover, when unlocking, the window sash still needs to be manually pushed to overcome the attraction force, resulting in a poor user experience.

[0005] Therefore, there is a need to provide an aluminum alloy casement window with a self-locking function to solve the above problems. Utility Model Content

[0013] A positioning mechanism is provided between two self-locking rods to drive the two self-locking rods to move relative to each other.

[0014] Preferably, the positioning mechanism includes two push rods, the ends of which are fixedly connected to the outer walls of two self-locking rods. An electric telescopic rod is fixedly connected to the outer walls of both self-locking rods, and a spring telescopic rod is fixedly connected to the opposite sides of the two self-locking rods near their top ends.

[0032] Aluminum alloy casement windows with self-locking function also include:

[0033] Two self-locking components 7 are located at the rear bottom of the two casement window bodies 6 and the aluminum alloy window frame 1, and are used to quickly lock the casement window bodies 6.

[0034] The movable metal plate 3 and the fixed metal plate 8 are provided. The bottom end of the movable metal plate 3 is fixedly connected to the top center of the movable screen window 4, and the top end of the fixed metal plate 8 is fixedly connected to the top end of the inner wall of the aluminum alloy window frame 1. The fixed metal plate 8 is located directly above the movable metal plate 3.

[0035] The self-locking component 7 includes:

[0036] The support base 702 is fixedly connected to the front side of the casement window body 6 near the bottom. Four U-shaped rods 711 are fixedly connected to the rear side of the support base 702. Two self-locking rods 706 are movably arranged on the inner wall of the four U-shaped rods 711. An L-shaped groove seat 705 is movably sleeved on the outer wall near the bottom of the two self-locking rods 706. The front side of the L-shaped groove seat 705 is fixedly connected to the rear side near the bottom of the aluminum alloy window frame 1.

[0037] A positioning mechanism is provided between two self-locking rods 706 to drive the two self-locking rods 706 to move relative to each other.

[0038] The positioning mechanism includes two push rods 707. The ends of the two push rods 707 are fixedly connected to the outer walls of two self-locking rods 706. An electric telescopic rod 708 is fixedly connected to the outer walls of the two self-locking rods 706. A spring telescopic rod 709 is fixedly connected to the opposite side of the two self-locking rods 706 near the top.

[0039] The support base 702 has four slots 713 on the rear side at the two self-locking rods 706. The outer walls of the two self-locking rods 706 are fixedly sleeved with two limiting bands 710. The front bottom ends of the four limiting bands 710 are fixedly connected with sliders 712. The outer walls of the four sliders 712 are slidably connected in the grooves at the bottom of the four slots 713. The top ends of the four slots 713 are fixedly connected with U-shaped rods 711. The two self-locking rods 706 are slidably connected in the four U-shaped rods 711.

[0040] A protective shell 701 is fixedly connected to the rear side of the support base 702. Two square grooves 703 are opened in the middle of the protective shell 701. The outer walls of the two push rods 707 are slidably connected in the two square grooves 703. A protective shell 704 is fixedly connected to the outer wall of the protective shell 701. The two electric telescopic rods 708 are fixedly connected to the inner wall of the protective shell 704 at their opposite ends.

[0041] In this embodiment, as Figure 1-4 As shown, 708 opens, and under the action of 707, it drives the two 706 to move relative to each other, compressing 709. Under the protection of 711, 710 and 712 on one side slide within 713, providing stable support for the movement of 706. This causes 706 to move into the L-shaped groove of 705, and then 708 opens in the opposite direction, pushing the two 710 to move in the opposite direction, locking 706 within 705, thus completing the rapid locking of 6.

[0042] Example 2

[0043] The difference from Embodiment 1 is that this embodiment discloses that the top end of the fixed metal plate 8 is electrically connected to an electric wire 10, the top end of the electric wire 10 passes through the aluminum alloy window frame 1 and is electrically connected to a battery 11, the bottom end of the battery 11 is fixedly connected to the inside of the aluminum alloy window frame 1, and the battery 11 is electrically connected to the electric telescopic rod 708.

[0044] In this embodiment, as Figure 1-2 and Figure 5-6 As shown, when it is necessary to open 6, push 5 to move 4 upward, and move 3 to combine with 8. Then, control 11 to open through 10, which in turn controls the two 708 to open. Push the two 707 to move relative to each other, which in turn moves the two 706 to move relative to each other, and then push 9, so that 6 can be opened quickly.

[0045] The working principle of this utility model is as follows: To achieve self-locking after 6 is closed, 9 drives 6 to move and close. During this process, 708 opens, and under the action of 707, the two 706s move relative to each other, compressing 709. Under the protection of 711, 710 and 712 on one side slide within 713, providing stable support for the movement of 706. This allows 706 to move into the L-shaped groove of 705, and then 708 opens in the opposite direction, pushing the two 710s to move in the opposite direction, locking 706 within 705, thus quickly locking 6. When 6 needs to be opened, 5 is pushed to move 4 upwards, causing 3 to move until it engages with 8. 10 controls 11 to open, thereby controlling the two 708s to open, pushing the two 707s to move relative to each other, causing the two 706s to move relative to each other, and then pushing 9, which facilitates the quick opening of 6.
