Abstract
The utility model discloses a lock for a plastic-steel door/window, which comprises a switch shaft including a rotatable locking shaft and a locking bar. The switch shaft is arranged in the middle of a static rod of the lock, and the static rod of the lock is made of special-shaped steel and can enhance the strength and the beauty of the static rod. The locking bar is arranged on two sides of the locking shaft, can circularly move around the locking shaft, and automatically displace with the opening/closing of the door/window; a cylindrical projection is arranged on the locking bar, and the locking bar is correspondingly locked with a locking hole above or below the door/window through the projection. The utility model has a unique structure that the door/window can be locked through the locking bar whenever the locking shaft is clockwise or counter-clockwise rotated, and therefore the use is convenient, and the locking bar unidirectionally rolls so as to enable the locking point to roll.
Description
Technical field
The utility model relates to the door lock field, particularly a kind of locking device that is applicable to that plastic-steel door and window is used.
Background technology
The locking device is the rod of control gate sash locking and unlatching, the transmission device of point with lock, can realize the Multi-point locking function of flat-open door and window, outstanding window.The existing locking device that is applied to plastic-steel door and window is normally: if is clockwise direction the lock window time, be counterclockwise when then opening a window.Because people are easily forgetful or along counterclockwise mistaken, but push away wrong direction when needing to lock window sometimes and opened a window, and pushed away wrong locking device direction lock window when will open a window, brought inconvenience to people's life.
The utility model content
