The invention belongs to the technical field of door locks, and particularly relates to a security door lock. The security door lock comprises a lock case, a rotating column and password buttons; theposition, close to the lower right corner of the lock case, of the front end face of the lock case is fixedly connected with a core column; the position, at the axis of the core column, of the front end face of the core column is rotationally connected with the rotating column; an inserting hole is formed in the front end face of the rotating column; a key is inserted in the inserting hole; through holes are evenly formed in the positions, over the rotating column, of the outer cambered surface of the rotating column; sliding holes are formed in the positions, at the through holes, of the inner cambered surface of the core column correspondingly; the interiors of the sliding holes are each connected with a first sliding column in an up-down sliding mode; the interiors of the through holesare each slidably connected with a second sliding column; and the password buttons are evenly arranged on the positions, on the upper right position, of the front end face of the lock case. Through the security door lock, the forcible entry cost of the door lock is effectively omitted, the structure is simple, practicability is high, meanwhile electric power is not needed, the application range iswide, and different environment requirements are met.
本发明属于门锁技术领域，具体的说是一种安防门锁，包括锁壳、转动柱和密码按钮；所述锁壳的前端面靠近锁壳的右下角位置固连有芯柱；所述芯柱前端面于芯柱的轴线位置转动连接有转动柱；所述转动柱的前端面开设有插孔；所述插孔的内部插接有钥匙；所述转动柱的外弧面于转动柱的正上方位置开设有均匀布置的通孔；所述芯柱的内弧面于通孔位置均开设有滑动孔；所述滑动孔内部均上下滑动连接有第一滑柱；所述通孔的内部均滑动连接有第二滑柱；所述锁壳的前端面于芯柱的右上方位置设有均匀布置的密码按钮；通过本发明有效的防止了门锁破拆的成本，结构简单实用性较高，同时无需电力，应用范围广，适用于不同环境的要求。
