Description

A system of anti-misoperation corner brackets for doors and windows Technical Field

[0001] This utility model relates to the field of corner mechanism technology, specifically a corner mechanism for preventing misoperation in system doors and windows. Background Technology

[0002] A door and window corner bracket is a decorative accessory used at the corner of a door or window. It is usually made of materials such as metal, plastic or wood and can connect the profiles on both sides of a door or window to meet various movement requirements during the opening and closing process.

[0003] Traditional corner mechanisms lack a reliable limiting structure when doors and windows are opened or closed (such as when switching between casement and tilt-and-turn modes), which may lead to user misoperation (such as forcibly switching modes in an incorrect state), resulting in component wear, transmission failure, or even damage to doors and windows. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this utility model provides a corner device for preventing misoperation of system doors and windows. It solves the problem that traditional corner devices lack a reliable limiting structure when opening and closing doors and windows, which may lead to user misoperation, resulting in component wear, transmission failure, or even damage to doors and windows.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a corner device for preventing misoperation in system doors and windows, comprising a connecting rod, a mounting rod, and a fixing plate. A stop block is fixedly connected to the surface of the connecting rod, and a fixing plate is fixedly connected to the surface of the mounting rod, which is also rotatably connected to the corner device via a rotating shaft. A limiting groove is formed on the surface of the fixing plate, and a placement groove is provided on the back of the corner device, with a spring installed in the inner cavity of the placement groove. A limiting block is fixedly connected to the bottom of the corner device, and the arc-shaped end of the corner device covers the surface of the fixing plate. The two ends of the spring are located in the limiting groove and are attached to the inner wall of the limiting groove. The limiting block and the stop block abut against each other.

[0006] Preferably, one end of the connecting rod is slidably sleeved in the inner cavity of the mounting rod.

[0007] Preferably, the inner cavity of the mounting rod is slidably fitted with a sliding element.

[0008] Preferably, a transmission plate is fixedly installed in the inner cavity of one end of the connecting rod.

[0009] Preferably, the transmission plate is located in the inner cavity of the mounting rod, and one end is fixed in the sliding member.

[0010] Preferably, the number of transmission plates is multiple, and they are stacked on top of each other.

[0011] This utility model provides a corner device for preventing misoperation in system doors and windows. Compared with the prior art, it has the following advantages:

[0012] The system uses a corner mechanism to prevent misoperation of doors and windows. By squeezing the corner mechanism, it moves to one side, separating the limit block from the stop block. This causes the connecting rod to slide within the inner cavity of the mounting rod. When the lock seat is rotated to open inward, the components will not squeeze the corner mechanism, allowing it to automatically reset under the spring force. This causes the opposite ends of the limit block and the stop block to abut against each other, thus preventing misoperation. Attached Figure Description

[0022] 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.

[0023] Please refer to Figures 1-8. This utility model provides a technical solution: a corner bracket for preventing misoperation of system doors and windows, including a connecting rod 1, a mounting rod 2, and a fixing plate 3. A stop block 7 is fixedly connected to the surface of the connecting rod 1, and a fixing plate 3 is fixedly connected to the surface of the mounting rod 2. A corner bracket 4 is also rotatably connected via a rotating shaft 5. A limiting groove 12 is formed on the surface of the fixing plate 3. A placement groove 10 is provided on the back of the corner bracket 4, and a spring 11 is provided in the inner cavity of the placement groove 10. A limiting block 6 is fixedly connected to the bottom of the corner bracket 4. The arc-shaped end of the corner bracket 4 covers the surface of the fixing plate 3. The two ends of the spring 11 are located in the limiting groove 12 and are attached to the inner wall of the limiting groove 12. The limiting block 6 and the stop block 7 abut against each other. A connecting post is provided on the surface of the fixing plate 3, which is directly installed on the surface of the mounting rod 2. Screws on both sides are used to fix the mounting rod 2 to the window sash. Then, the external lock seat is assembled. The components of the connecting rod 1, the mounting rod 2, and the lock seat are existing technologies and will not be described in detail.

[0024] During installation, first, the fixing plate 3 is fixed to the surface of the mounting rod 2. Then, the corner piece 4 is rotatably connected to the mounting rod 2 through the rotating shaft 5, and one end of the corner piece 4 covers the fixing plate 3, so that the internal spring 11 abuts against the inner wall of the limiting groove 12. Then, multiple transmission plates 8 are stacked together, one end is fixed in the connecting rod 1, and the other end is located in the mounting rod 2. At the same time, the connecting rod 1 is also slid in the mounting rod 2, and one end of the transmission plate 8 is fixed by the sliding member 9. In this way, rotating the corner piece 4 can drive the connecting rod 1 to slide in the mounting rod 2, so the connection of the transmission plate 8 will not fall off.

[0025] When the lock seat is rotated inwards via an external connection, the components of the lock seat will press the corner mechanism 4, causing the corner mechanism 4 to move to one side and separating the limit block 6 from the stop block 7. This causes the connecting rod 1 to slide within the cavity of the mounting rod 2. When the lock seat is rotated inwards to open, the components will not press the corner mechanism 4, allowing the corner mechanism 4 to automatically reset under the elastic force of the spring 11, causing the opposite ends of the limit block 6 and the stop block 7 to abut against each other, thereby preventing accidental operation.

[0026] Furthermore, one end of the connecting rod 1 is slidably sleeved in the inner cavity of the mounting rod 2. The inner cavity of the mounting rod 2 is slidably sleeved with a sliding member 9. A transmission plate 8 is fixedly installed in the inner cavity of one end of the connecting rod 1. The transmission plate 8 is located in the inner cavity of the mounting rod 2, and one end is fixed in the sliding member 9. Through the connection between the transmission plate 8 and the connecting rod 1 and the mounting rod 2, after the corner 4 rotates, the connecting rod 1 can be pulled to make the connecting rod 1 slide in the mounting rod 2.

[0027] There are multiple transmission plates 8, which are stacked on top of each other. The transmission plates 8 are flexible and can be bent. They are used in groups of 2 to 5 stacked together. In this application, 3 transmission plates 8 are used. Multiple transmission plates 8 can increase the connection strength.

[0028] During operation or use, when the lock seat is rotated inward, the components of the lock seat will press the corner mechanism 4, causing the corner mechanism 4 to move to one side. The corner mechanism 4 can press left and right depending on the left and right rotation of the lock seat. At the same time, the spring 11 will bend within the limiting groove 12 opened in the fixed plate 3, separating the limiting block 6 from the stop block 7. In this way, after the transmission plate 8 is fixed by the sliding member 9, it is connected to the connecting rod 1 and the mounting rod 2. Thus, the sliding member 9 slides the connecting rod 1 in the inner cavity of the mounting rod 2, so that the side of the stop block 7 blocks the limiting block 6. When the lock seat is rotated inward, the components will not press the corner mechanism 4, and the corner mechanism 4 will automatically reset under the elastic force of the spring 11. The opposite ends of the limiting block 6 and the stop block 7 will abut against each other to achieve a limit, preventing the connecting rod 1 from sliding, thus forming a self-locking mechanism and preventing accidental operation.
