[0002] Modern doors and windows are usually in the form of the side of the door and window body hinged to the side of the door and window frame. When opening the door, it is pulled open in a hinged form. In this case, the weight of the door and window body falls entirely on the hinges of the two hinges, which requires high strength of the hinges. Now, in occasions such as sun rooms, heavier doors and windows are used, and the supporting force of conventional hinges is not enough. If hidden hinges installed above and below the doors and windows are used, it will be even more difficult to support. In order to solve the above technical problems, the applicant has applied for a door and window load-bearing device (application number is CN202421953205.7), including a first connecting member, a connecting rod and a second connecting member, the first connecting member and the second connecting member are respectively connected to the door and window frame and the side of the door and window body, and one end of the connecting rod is hinged to the first connecting member and the other end is movably connected to the second connecting member. However, during the opening and closing process of the doors and windows, the connecting rod is swung on the first connecting piece, and will tilt up during the swinging process. After long-term use, the connecting rod is prone to bending and deformation, causing damage, which not only reduces the service life of the connecting rod, but also affects the normal use of the doors and windows. Therefore, based on the above problems, the applicant has made further improvements to the above technology. Summary of the invention

[0003] Based on the above problems, the present invention provides a load-bearing component for doors and windows with a simple and stable structure and increased service life.

[0005] By adopting the above technical solution, when the door and window are in a fully closed state, the connecting seat and the mounting plate are in the same vertical plane. Preferably, the mounting plate is fixedly installed at the side position of the door and window main body, and the connecting seat is fixedly installed at the side position of the door and window frame. The mounting plate is located above the connecting seat and is used to support the connecting seat. When all parts are installed, the connecting seat installed on the door and window frame will transmit the weight of the door and window frame to the mounting plate through the transmission rod, so that the door and window frame will be suspended by the transmission rod, sharing the pressure of the hinge, increasing the load-bearing capacity of the door and window, and the structure is simple and stable. With such an arrangement, when the door is opened, When the window is opened, the connecting seat installed on the door and window frame will move with the opening of the door and window. When the connecting seat moves, the transmission rod is driven to swing along the direction of the connecting seat. When the opening angle between the door and window frame and the door and window body is greater than 90°, the connecting seat will rotate relative to the connecting block along the opening direction of the door and window. The connecting block is used to compensate for the swing range of the transmission rod and complete the opening of the door and window frame and the door and window body from 0° to 180°, avoiding bending and deformation of the transmission rod during the door and window opening process, resulting in damage, ensuring the normal use of the doors and windows, while increasing the service life of the transmission rod and further improving the reliability of the structure.

DETAILED DESCRIPTION

[0035] This specific embodiment is merely an explanation of the present invention and is not a limitation of the present invention. After reading this specification, those skilled in the art may make non-creative modifications to the present embodiment as needed. However, as long as they are within the scope of the claims of the present invention, they are protected by the patent law.

[0036] See attached Figure 1-8The present invention discloses a load-bearing component for doors and windows, comprising a mounting plate 1, a connecting seat 2 and a transmission rod 3. The mounting plate 1 is located above the connecting seat 2 and is used to support the transmission rod 3. The transmission rod 3 is used to support the connecting seat 2. A connecting block 4 is hingedly provided on the connecting seat 2. The connecting seat 2 rotates left and right relative to the connecting block 4 along the door and window opening and closing direction. The hinged end of the connecting block 4 is close to one end of the transmission rod 3, and the other end is provided with a through groove 5. One end of the transmission rod 4 is hinged to the mounting plate 1, and the other end passes through the through groove 5 and is suspended in the through groove 5. When the door and window are in a fully closed state, the connecting seat 2 and the mounting plate 1 are in the same vertical plane. Preferably, the mounting plate 1 is fixedly mounted on the side of the door and window body 27, and the connecting seat 2 is fixedly mounted on the side of the door and window frame 28. The mounting plate 1 is located above the connecting seat 2 and is used to support the connecting seat 2. When all parts are installed, the connecting seat 2 installed on the door and window frame 28 will transfer the weight of the door and window frame 28 to the mounting plate 1 through the transmission rod 3, so that the door and window frame 28 will be suspended by the transmission rod 3, and the door and window frame 28 will be suspended by the transmission rod 3. The hinge pressure is borne, and the bearing capacity of the door and window is increased. The structure is simple and stable. When the door and window are opened, the connecting seat 2 installed on the door and window frame 28 will move with the opening of the door and window. When the connecting seat 2 moves, the transmission rod 3 is carried to swing along the direction of the connecting seat 2. When the opening angle between the door and window frame 28 and the door and window body 27 is greater than 90°, the connecting seat 2 will rotate relative to the connecting block 4 along the door and window opening direction. The connecting block 4 is used to compensate for the swing range of the transmission rod 3, complete the opening of the door and window frame 28 and the door and window body 27 from 0° to 180°, and avoid the bending and deformation of the transmission rod 3 during the door and window opening process, causing damage, ensuring the normal use of the door and window, while increasing the service life of the transmission rod 3, and further improving the reliability of the structure.
