TECHNICAL FIELD
[0001] The utility model relates to door and window hardware fitting technical field, concretely relates to a locking component for casement window. BACKGROUND
[0002] The casement window realizes locking, upper suspension, inner falling, opening and closing and locking opening angle function by hardware fitting. The locking function is not only related to the sealing performance of the window, but also directly related to the anti-theft safety performance. The casement window realizes locking by the cooperation of the locking point and the locking seat. The locking point is usually installed in the lock strip slot of the window sash, and the locking seat is installed in the installation slot of the window frame. The locking point is connected with the lock box through the linkage lock strip. The window opening and closing are controlled by the handle to control the lock box. The lock box links the locking point and the locking seat. At present, the locking component of the casement window usually adopts L-shaped locking seat. The locking column is directly arranged on the linkage lock strip or arranged on the inner falling lock rod. When the locking action occurs, the linkage lock rod drives the locking column to move to the locking seat position, and the locking column is clamped on the L-shaped locking seat, and the window is in the locked state. Then the locking component is single-point type. Improper operation can easily cause loosening or deformation, which leads to difficult locking or complete locking of the window, affects the sealing performance, and causes personal and property losses once intentionally damaged.
