Magnetic-force limiting stopper for internally-windowed hardware

A magnetic-force limiting stopper for internally-windowed hardware belongs to a magnetic-force limiting stopper and resolves the problem that doors and windows with the function of firstly inclining to be opened have no opening limiting functions during firstly inclining to be opened and have potential safety hazards. The limiting stopper comprises a limiting blocking sheet, a limiting block and a handle, wherein the limiting blocking sheet is a permanent-magnet limiting blocking sheet, and the handle is fixedly arranged on the upper end face of the limiting block through the limiting blocking sheet. The limiting block is installed in a groove where a lock point of hardware for doors and windows with the functions of firstly inclining to be opened slides, namely stroke of the lock point of the hardware can be limited by the limiting block. When limited by the limiting block, doors and windows can only incline to be opened instead of being opened horizontally, thereby improving safety of doors and windows when the doors and the windows incline to be opened to ventilate. The limiting stopper is applied to horizontally-opened internally-inclined doors and windows.
