Abstract
The utility model relates to a hardware lockset, in particular to a locking device of a door and window multi-point lock, comprising locking points arranged on a pull rod and locking blocks which are arranged on a door and a window and matched with the locking points, wherein the locking blocks are provided with latch grooves; and the locking points are provided with bosses. With the locking device, the latch grooves are arranged on the locking blocks and the bosses are arranged on the locking points smartly. Even though the window is pressed, the edges of the latch grooves on the locking blocks can block the bosses on the locking points so as to enable the locking points not to be separated from the latch grooves. Therefore, the locking device is simple and reasonable in structure, and simultaneously has the advantage of better safety performance compared with the prior art.
Description
Technical field
The utility model relates to a kind of five metals lockset, relates in particular to a kind of locking system of door and window multi-point lock.
Background technology
