The invention discloses a door lock protection device for preventing a key from being not pulled out. The device comprises a working door, wherein a lock cylinder is fixedly mounted in the working door, a protection box is fixedly mounted on the left end surface of the working door, left and right sliding grooves are symmetrically formed in the protection box up and down, sliding groove racks areslidably mounted in the left and right sliding grooves, a contact shaft is rotationally installed on the rear wall face of an inner cavity of the protection box, a front bevel gear, a rear bevel gearand a contact gear are sequentially and fixedly installed on the contact shaft from front to back, and the contact gear is meshed with the sliding groove racks. According to the device, when key pulling-out is forgotten during door locking, when the condition that the door key is not pulled out is detected, the device may automatically jam the door on a lock frame, then the door can only be openedthrough a false key, safety of a household and safety of people are protected, meanwhile, kinetic energy generated when the door rotates is collected to generate electricity, and the door does not need to be powered on.
本发明公开了一种防止钥匙未拔出的门锁保护装置，包括工作门，所述工作门中固定安装锁头，所述工作门左端面固定安装防护箱，所述防护箱中上下对称设有左右滑槽，所述左右滑槽中滑动安装滑槽齿条，所述防护箱内腔后壁面转动安装接触轴，所述接触轴由前至后依次固定安装前后锥齿轮、接触齿轮，所述接触齿轮与所述滑槽齿条啮合，本发明在锁门时候忘记拔走钥匙时候，能检测到当门钥匙未拔出时候，本发明能自动使门卡死在门框上，进而通过备用钥匙进行开启才能打开门，保护了家庭和人员的安全，同时，本发明收集门旋转时候的动能发电，无需对门进行通电。
