Crank lock
The invention relates to a crank lock which is characterized in that a guide connecting structure of a lock cylinder protective cover guide arranged on a handle comprises a pivoting foot, a guide foot and guide grooves formed in the two transverse sides of the handle, a rocker arm mounting seat is arranged on the back side of the handle, a guide rocker arm is pivoted on the rocker arm mounting seat, and the guide rocker arm swings in the direction corresponding to the length direction of the handle; the extending direction of the guide groove is matched with the swinging direction of the guide rocker arm, a guide foot on the lock cylinder protection cover is slidably and rotatably supported in the guide groove, an avoiding channel leading to the rocker arm installation base is formed in the top face of the handle, a pivot joint foot of the lock cylinder protection cover extends into the avoiding channel and is hinged to the top end of the guide rocker arm, and the guide rocker arm is provided with a vertical position. The first deflection position and the second deflection position are located on the two sides of the vertical position respectively, and the lock cylinder protection cover abuts against the handle at the covering position and the opening position. The lock cylinder protection structure has the advantages of being compact in structure and convenient to use.
本发明涉及一种摇把锁，设于手柄上的锁芯防护盖导引的导引连接结构引导包括枢接脚、导引脚及设于手柄横向两侧上的导引槽，在手柄背侧设有摇臂安装座，摇臂安装座上枢装有导引摇臂，导引摇臂沿与手柄长度方向对应的方向摆动，导引槽延伸方向和导引摇臂摆动方向相适应，锁芯防护盖上导引脚可滑动且可转动地支承于导引槽内，手柄顶面设有通向摇臂安装座的避让通道，锁芯防护盖的枢接脚伸入避让通道并铰接于导引摇臂顶端，导引摇臂具有一竖直位置，第一偏摆位置及第二偏摆位置，第一偏摆位置和第二偏摆位置分别位于竖直位置两侧，锁芯防护盖在遮盖位置、开启位置均贴靠于手柄上。具有锁芯防护结构的结构紧凑及使用方便的优点。
