Abstract

A lock for steel frame window wings which abut when closed comprises a main lock body, a secondary lock body, a fixing plate and a connecting rod. A lockingdog which is capable of rotating is arranged inside the main lock body. The tail end of the lockingdog is provided with an unlocking cam which can make the main lock bolt to move. A secondary and a main lock hook which extends into the secondary lock body and main lock body and joggles with a secondary and the main lock bolt are connected with an upper fixing plate and a lower fixing plate. When the key is inserted into the lock hole to rotate the lockingdog, the unlocking cam dials the main lock bolt to move, thereby separating the main lock hook from the main lock bolt. Simultaneously, the connecting rod for connecting the main lock bolt and the secondary lock bolt moves to separate the secondary lock bolt from the secondary lock hook, thereby opening two steel windows. If the lock bolt contacts with the lock hook, a reset spring under the lock bolt acts to close two steel windows, thereby realizing anti-theft and anti-lifting functions with good shape and practicability.
