The invention belongs to the technical field of mortice door locks, and in particular relates to an anti-break mortice door lock head. The anti-break mortice door lock head comprises a lock cylinder shell, a left lock head, a right lock head and a shifting piece, wherein the left lock head and the right lock head are mirror images of each other and installed on the lock cylinder shell; a lock cylinder is installed in the right lock head; the shifting piece is installed between the left lock head and the right lock head and connected with the lock cylinder; an installation groove is formed on the upper part of the lock cylinder shell; an anti-break rod is installed in the installation groove; positioning clamping grooves are formed in the bottom of the installation groove; positioning clamping blocks are arranged at the bottom of the anti-break rod and can be inserted into the positioning clamping grooves; pin tumbler holes are formed in the lock cylinder shell; inner ejector pin tumblers are installed in the pin tumbler holes through springs; and the openings of the pin tumbler holes are positioned at the bottom of the installation groove. The anti-break mortice door lock head is simple in structure, convenient to install, and capable of effectively preventing violent breaking, being fixedly locked, and preventing the broken lock head from being rotated or unlocked by the shifting piece.
本发明属于插芯门锁技术领域，具体的说是一种防断插芯门锁锁头，包括锁芯壳、左锁头、右锁头和拨片，所述左锁头与右锁头互为镜像,且安装在锁芯壳上；所述右锁头中安装有锁芯；所述拨片安装在左锁头与右锁头中间；所述拨片与锁芯相连接；所述锁芯壳上方开设有安装槽；所述安装槽中安装有防断杆；所述安装槽底部开设有定位卡紧槽；所述防断杆底部设置有定位卡紧块；所述定位卡紧块可插入定位卡紧槽中；所述锁芯壳中设置有弹子孔；所述弹子孔中通过弹簧安装有内顶弹子；所述弹子孔的开口位于安装槽底部；本发明结构简单，安装方便，能够有效的防止暴力打断，可固定锁定防止转动断裂的锁头或拨片开启锁头。
