The invention relates to a handle locking mechanism of a handle door and window lock, which comprises a mounting seat, a plane cam, a locking sleeve and a handle which are sequentially inserted by taking a transmission square strip as a center line, the handle drives the transmission square strip to rotate, mounting hole columns are symmetrically arranged on the mounting seat, arc-shaped sliding chutes are symmetrically arranged on the plane cam, and the locking sleeve is arranged in the arc-shaped sliding chutes. The locking sleeve is provided with a connecting hole, the connecting hole is opposite to the mounting hole column, the screw penetrates through the connecting hole and the mounting hole column to be fixedly mounted on the door and window profile, the locking sleeve is axially provided with a through hole, and the lock pin is sleeved with the spring and movably inserted into the through hole. A pressure plate is concentrically fixed on the transmission square strip on the outer side of the locking sleeve, a positioning hole is formed in the pressure plate, one end of a lock pin is matched with the plane cam, and the other end of the lock pin is matched with the positioning hole. When the plane cam rotates, one end of the lock pin can be inserted into the positioning hole, the handle cannot rotate any more, mistaken opening operation can be effectively prevented, and the lock has the advantages of being simple and compact in structural design, small in installation base area and high in reliability.
本发明涉及一种执手门窗锁的执手锁定机构，包括以传动方条为中心线依次插接的安装座、平面凸轮、锁定套和执手，执手带动传动方条旋转，在安装座上对称设置安装孔柱，平面凸轮上对称设置弧形滑槽，安装孔柱插接在弧形滑槽中可相对滑动，锁定套上设置连接孔，连接孔与安装孔柱相对，螺钉穿过连接孔和安装孔柱固定安装于门窗型材，在锁定套上轴向开设通孔，锁销外套弹簧活动插接在通孔中，在锁定套外侧的传动方条上同心固定压盘，压盘上开设定位孔，锁销的一端与平面凸轮相配合，另一端与定位孔相配合。平面凸轮转动时可使锁销的一端插入定位孔，执手不能再转动，可以有效防止误开启操作，具有结构设计简单紧凑、安装座的面积小、可靠性强的优点。
