Description

Rolling screen door and window anti-theft lock with bidirectional linkage locking mechanism

Technical Field

The invention relates to the technical field of roller shutter locks, in particular to an anti-theft lock for roller shutter doors and windows with a bidirectional linkage locking mechanism.

Background

The traditional mechanical roller shutter lock generally realizes the transverse auxiliary anti-theft function of the bolt in place for a lock core driving gear transmission structure. The main manifestations are five disadvantages: firstly, a gear transmission structure device for controlling stroke or displacement is easily subjected to position deviation under the influence of door body vibration, and the phenomena of lock head and tooth clamping are caused, so that mechanical faults are easily caused. Secondly, the displacement of the roller shutter door and window is realized by the rail, the bolt anti-theft function can only be an auxiliary security protection function, and the door body is easily pried up when the rail is vertically prized, so the bolt on the roller shutter door and window does not realize the real anti-theft effect. Thirdly, the stress point is single, and when the roller shutter door and window is attacked by typhoon in the coastal area, the roller shutter door and window often causes secondary damage to people and property by one wolf. Fourthly, the key is needed when the existing shutter door is opened and closed, and the emergency opening mode is lacked when the emergency situation occurs inside the door body. Fifth, the present invention is limited by the existing gear structure device, which seriously hinders the automation and intelligence development trend and innovation foundation of the rolling door and window industry, and therefore, we propose an anti-theft lock for rolling door and window with a bidirectional linkage locking mechanism to solve the above problems in the background art.

Disclosure of Invention

The invention aims to provide a rolling door and window anti-theft lock with a bidirectional linkage locking mechanism, which is opened and closed by using a crank block transmission mechanism and is a rolling door and window lock with a transverse and longitudinal bidirectional integrated locking mechanism.
