Problems solved by technology
However, the doors and windows in the prior art have the problem that the handle is easy to loosen the fasteners (bolts) when they are in use; specifically, the handle and the frame (profile) are usually directly connected by bolts. During the opening or closing process, the connection between the handle and the frame will be subject to torque or tension, especially in heavy doors and windows, the torque or tension will be more significant at the connection between the handle and the frame, that is, The clamping force formed on the frame only by the cooperation of the bolt and the handle is limited. On the one hand, due to the limitation of the thickness of the profile, that is, the anti-deformation ability of the profile when it is stressed, on the other hand, when the thread is set on the profile, due to the The limitation of the thickness of the profile makes the profile unable to withstand a relatively large tightening moment; therefore, after a long time of use, the connection between the handle and the frame will be subject to the above-mentioned force, which will make the handle prone to loosening The problem

The invention provides a door and window which comprises a frame body, a handle and a reinforcing back plate, the frame body is provided with an installation position used for installing the handle, the reinforcing back plate is located on the first face of the installation position, the handle is located on the second face of the installation position, and the reinforcing back plate corresponds to the handle. The handle penetrates through the mounting position of the frame body, the handle is fixedly connected with the reinforcing back plate, and the handle and the reinforcing back plate are matched with each other and clamped on the mounting position; the door and window has the advantages of being reasonable in structure and reliable in handle connection.
Description
technical field [0001] The invention belongs to the technical field of hardware, in particular to a door and window. Background technique [0002] Doors or windows are the basic components of modern buildings, and in order to facilitate the opening or closing of doors and windows, handles are often installed on doors and windows, and then the handles are used to control the opening or closing of doors and windows. However, the doors and windows in the prior art have the problem that the handle is easy to loosen and the fasteners (bolts) are loosened during use; specifically, the handle and the frame (profile) are usually directly connected by bolts, and the door and window are During the opening or closing process, the connection between the handle and the frame will be subjected to torque or tension, especially in heavy doors and windows, the torque or tension at the connection between the handle and the frame will be more significant, that is, The clamping force formed on...
