The invention relates to an improved handle door and window lock mistaken unlocking prevention locking mechanism. The mechanism comprises a handle body, a mounting seat, a transmission square strip and a square strip sleeve, a first through hole is axially formed in the square strip sleeve, a locking pin is movably inserted into the first through hole, one end of the locking pin is in sliding insertion fit with a locking hole formed in the mounting seat during locking, the other end of the locking pin is attracted and positioned with a positioning magnetic block fixedly installed on the handle body in the open state, a push-pull piece is fixed to the locking pin, a positioning steel ball, a spring and a plug are sequentially installed in a second through hole formed in the square strip sleeve in the radial direction, the spring abuts against the positioning steel ball, and in a locked state, the positioning steel ball is in positioning fit with a groove formed in the locking pin. When one end of the locking pin is inserted into the locking hole in the mounting base, the handle body and the square strip sleeve are connected into a whole, the handle body cannot rotate any more, mistaken opening operation of children can be effectively prevented, and the mechanism has the advantages of being simple and compact in structural design, convenient to operate and use by adults and high in reliability.
本发明涉及一种改进的执手门窗锁防误开锁定机构，包括执手体、安装座、传动方条和方条套筒，方条套筒上轴向开设第一通孔，锁定销活动插接在第一通孔中，锁定销的一端在锁定时与安装座上开设的锁定孔滑动插接配合，锁定销的另一端在开启状态下与执手体上固定安装的定位磁块吸合定位，锁定销上固定推拉件，方条套筒上径向开设的第二通孔中依次安装定位钢珠、弹簧和堵头，弹簧抵压在定位钢珠上，在锁定状态时，定位钢珠与锁定销上设置的凹槽形成定位配合。锁定销的一端插入安装座上的锁定孔时，执手体和方条套筒连接成一体，执手体即不能再转动，可以有效防止儿童的误开启操作，具有结构设计简单紧凑、成人操作使用方便、可靠性强的优点。
