[0021] The utility model embodiment provides a safety anti-lock door lock device, such as Figure 1-4 As shown, it includes a door panel 1, a door lock panel 2, a handle 3, and an anti-lock head 4: the front of the door lock panel 2 is fixedly connected with a mounting column 5, the outer wall of the mounting column 5 is movably connected with a positioning ring 6, the outer wall of the mounting column 5 is movably connected with a mounting block 7, the front of the mounting block 7 is provided with a mounting groove 8, the bottom of the mounting block 7 is fixedly connected with a cover box 9, the front of the cover box 9 is fixedly connected with a guide seat 10, the top of the cover box 9 is fixedly connected with a limiting hook 11, the outer wall of the cover box 9 is movably connected with a cover cover 12, the back of the cover cover 12 is fixedly connected with a guide strip 13, the top of the cover cover 12 is fixedly connected with a hook rope 15, and the front of the cover cover 12 is fixedly connected with a push plate 16.
[0022] It should be noted that, since the existing safety anti-lock door lock device has no protective structure at the anti-lock knob after anti-locking, when the anti-lock knob is exposed to the outside, it is easy for children at home to play and repeatedly touch it by mistake, causing the anti-lock knob to open, thereby bringing hidden dangers to safety. Therefore, in order to solve the problem that the existing anti-lock knob has no protective structure after anti-locking and is easy to be accidentally touched by children at home repeatedly, causing the anti-lock knob to open, the present solution provides a cover box 9, which is convenient for installing it outside the door lock panel 2, so that the anti-lock head 4 can be covered and protected. The cover 12 outside 9 can form a closed state for the anti-lock head 4 to prevent the anti-lock head 4 from being directly exposed to the environment. At the same time, the cover 12 can slide up and down outside the cover box 9, which is convenient for opening and closing the anti-lock head 4. The cover 12 can be connected to the limit hook 11 on the top of the cover box 9 through the cooperation of the top hook rope 15, and can stably connect the cover 12 to the cover box 9, avoiding the situation where the anti-lock knob is easily opened by repeated accidental touching by children at home when playing, effectively improving the safety of door lock use and avoiding safety hazards.
