Description

Technical Field

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

[0002] With the rapid development of the construction industry, aluminum alloy doors and windows have been widely used in residential and commercial buildings due to their advantages such as aesthetics, durability, and corrosion resistance.

[0003] However, existing aluminum alloy door and window locking structures have certain defects. In daily use, door and window handles lack effective limiting measures. When there are children in the house, children may touch the door and window handles out of curiosity, which can easily lead to the doors and windows being opened accidentally. This situation can not only cause heat loss and noise intrusion, but may also cause serious safety accidents such as children falling, posing a great threat to the family. Therefore, we propose a locking structure for aluminum alloy doors and windows. Utility Model Content

[0004] To address the shortcomings of existing technologies, the purpose of this utility model is to provide a locking structure for aluminum alloy doors and windows that prevents accidental opening. This solves a problem inherent in existing aluminum alloy door and window locking structures, such as the lack of effective restraint mechanisms on door and window handles during daily use. When children are present, they may touch the handles out of curiosity, easily leading to accidental opening of doors and windows. This not only causes heat loss and noise intrusion but may also lead to serious safety accidents such as accidental falls, posing a significant hazard to the family.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a locking structure for aluminum alloy doors and windows, including a mounting base, a rotating shaft fixedly connected to the top of the front of the mounting base at the central axis, a limiting plate movably connected to the front of the rotating shaft via a bearing, a limiting hook provided on one side of the limiting plate, a handle fixedly connected to the bottom of the limiting plate, a hollow block fixedly connected to the bottom of the front of the mounting base at the central axis, springs fixedly connected to both sides of the bottom of the hollow block's inner cavity, a rectangular plate fixedly connected to the top of the springs, a connecting frame fixedly connected to one side of the rectangular plate, a sleeve fixedly connected to the top of the rectangular plate, and the top of the sleeve being inserted into the handle.

[0006] Preferably, a movable groove is provided at the bottom left side of the mounting base, a battery is provided on the inner wall of the movable groove, a buzzer is fixedly connected at the central axis of the left side of the mounting base, and a contact switch is provided at the central axis of the bottom of the rectangular plate.

[0007] Preferably, a connecting seat is fixedly connected to one side of the limiting hook, and both the connecting seat and the mounting seat have mounting holes on one side.

[0008] Preferably, a rectangular groove is provided at the bottom of the hollow block, and the inner cavity of the rectangular groove is slidably connected to the connecting frame.

[0009] Preferably, a connecting groove is provided at the top of the hollow block's inner cavity, and the inner cavity of the connecting groove is movably connected to the sleeve.

[0010] Preferably, a sealing door is movably connected to the bottom left side of the mounting base, an elastic telescopic rod is fixedly connected to the central axis at the bottom of the hollow block cavity, and a contact switch is fixedly connected to the top of the elastic telescopic rod.

[0011] Compared with the prior art, this utility model provides a locking structure for aluminum alloy doors and windows, which has the following advantages:

[0012] 1. In this utility model, pulling down the connecting frame causes the rectangular plate to move, the rectangular plate sleeve to descend, and then rotating the handle causes the limiting plate to rotate. After the limiting plate engages with the limiting hook, the connecting frame can be released. At this time, the rectangular plate is moved by the spring force, and the rectangular plate moves the sleeve, so that the sleeve engages with the handle, thereby limiting the handle and preventing children from directly rotating the handle.

[0013] 2. When a child pulls down the connecting frame, the rectangular plate moves and contacts the contact switch, squeezing the contact switch and causing the buzzer to sound, alerting the guardian and allowing for timely monitoring. Attached Figure Description
