A pull-type retractable and rotating lock tongue control mechanism includes a lock body shell and a retractable and rotating lock tongue. The retractable and rotating lock tongue comprises a shell component and a tongue body component. The tongue body component comprises a tongue body, a retractable platform and a spring. One end of the spring is fixed at the bottom of the shell component, and the other end is connected with a retractable platform. The tongue body is rotatably mounted on the retractable platform. With the expansion platform, the tongue body has rectangular ear protrusions on both sides, which match the ear protrusions. There are L-shaped locking grooves on the left and right sides of the lock shell. When the clamp plate inserts the locking groove from below, the ear protrusion is blocked, so that the tongue body can not rotate. The locking body shell includes the left half of the lock body shell and the right half of the lock body shell. The clamp pin is forked, and the upper part is forked. The first pin axle passes through the guide groove so that the pin can be movably installed in the lock body shell. The pull handle extends out of the lock body shell, and the reset spring elastically connects the pin and the lock body shell. Its advantage is that it solves the control problem of opening and closing the retractable and rotating lock tongue, so that both doors and windows can be concealed and locked. When concealed, doors and windows can be opened on both sides of doors and windows.

拉动式可伸缩和转动的锁舌控制机构
本专利技术涉及与门窗有关的特殊措施,涉及锁舌,尤指一种拉动式可伸缩和转动的锁舌控制机构。
技术介绍
锁体是一种常用五金配件,安装于门窗扇上。门窗通过锁体在门窗框和门窗扇之间负责门窗的开启和锁闭。锁体上使用的锁舌是其核心零件,直接起到门窗的开启和闭锁作用。现有技术的锁体锁舌只能作前后伸缩运动,此结构的锁舌单一功能决定了门窗只能往一边开启和直接锁闭功能。在现实生活中,有时我们需要门窗的两边均能开启,只把门虚关,即门不闭锁,只起到防风吹开的作用。现有技术的锁舌不能适用这一需求。为解决这一问题,本申请人就可伸缩和转动的锁舌另外申请了专利:参见附图1~12,所述一种可伸缩和转动的锁舌,包括壳体组件2和舌体组件1,其特征在于:所述舌体组件1包括舌体11、伸缩平台12和弹簧13,弹簧13一端固定于壳体组件2的底部,另一端连接伸缩平台12,舌体11可转动地装于伸缩平台12上,随伸缩平台12伸缩,所述舌体11两侧有长方形状的耳凸112,与所述耳凸112相配,在锁壳21上有长方形的闭锁槽22,当卡销3插入闭锁槽22后阻挡耳凸112,使舌体11不能转动 ...
