Abstract
Description
Technical Field
[0001] The utility model specifically relates to the technical field of wind braces, and particularly relates to a wind brace for a push window. Background Art
[0002] The sliding brace uses a planar link mechanism to realize the opening and closing of the window sash. Therefore, the load-bearing capacity of the sliding brace plays a crucial role in the safety of the cantilevered window sash. The load-bearing capacity of the sliding brace for the window sash is mainly reflected on the support arm of the planar link mechanism. The existing support arm only considers the load-bearing capacity of the window sash in the gravity direction, and uses the support force of the support arm to resist the gravity of the window sash itself. However, for the cantilevered window sash, under bad weather such as strong winds, the continuous shaking generates torque, and the support arm is prone to deformation, resulting in damage to the window sash.
[0003] The existing wind braces are fixed to the window through screws. However, during long-term use, with continuous opening and closing, the screws will become loose. Especially for plastic-steel windows, after being stressed, the threaded holes will crack due to the stress; the installation stability of the window is poor, and the number of times it can be opened is less. Summary of the Utility Model
[0004] The purpose of the utility model is to provide a wind brace for a push window, which is fixed to the window by means of lifting and two clamping fixations; the contact area between the window and the wind brace is increased, the damage to the window caused by screws is reduced, the installation stability of the window is improved, and the number of times the window can be opened is increased; to solve the technical problems raised in the above background art.
[0005] To achieve the above purpose, the utility model provides the following technical solutions:
[0006] A wind brace for a push window includes a main brace fixed to the window frame. Both ends of the main brace are connected with a first hinge piece and an intermediate hinge piece through a rotating shaft. Among them, a connecting piece is connected to the main brace at the 1 / 3 position of the first hinge piece through a rotating shaft; the connecting piece is movably connected with a slider arranged on the main brace through a rotating shaft; a second hinge piece is further fixed on the intermediate hinge piece, and the second hinge piece is movably connected with the first hinge piece through a rotating shaft; the second hinge piece is arranged in a U shape, and rotating lock catches are threadedly connected to both ends of the second hinge piece;
