[0030] As shown in FIG. 1 and FIG. 2, the present invention provides a portable safety door stopper, which includes a stopper 4 for attaching to the inner side of the door, a base 2 laid flatwise on the ground, and a supporting post 3 rotatably connected between the stopper 4 and the base 2. The stopper 4 is internally provided with a locking hook component, and the stopper 4 can always cling to a set position on the inner side of the door through locking action, so as to realize the installation of the safety door stopper; the base 2 is rotatably connected with the stopper 4; when in use, the angle between the stopper 4 and the base 2 can be adjusted according to the size of the doorway space, allowing the base 2 to be adjusted to the uneven floor surface, and still safely supporting the stopper 4 in use.

[0031] As shown in FIG. 2, the stopper 4 is formed by fixedly connecting two half shells through screws. The locking hook component includes a movable locking hook 8 built in the stopper 4 and an adjusting screw 5 for driving the movable locking hook 8 to slide. The outer end of the movable locking hook 8 is bent to form a first folded edge 81, and the inner end of the movable locking hook 8 is in transmission connection with the adjusting screw 5. The movable locking hook 8 slides in the stopper 4 through the adjusting screw 5, and its height position is adjusted according to the space under the door to clamp the door bottom, which does not affect the adjustment. In this embodiment, the height position of the movable locking hook 8 is adjusted by the screw transmission of the adjusting screw 5, which has good self-locking performance. In some embodiments (not shown in the figure), a worm gear mechanism or a cam jack-up mechanism can also be used to realize self-locking protection after adjusting the height position of the movable locking hook 8.

[0032] In this embodiment, the outer end of the movable locking hook 8 forms an L-shaped block through the first folded edge 81 formed by bending. In order to further improve the clamping of the stopper 4 and the first folded edge 81 to the door, the top of the first folded edge 81 and the side surface of the stopper 4 are knurled to increase the friction. However, in some embodiments (not shown in the figure), the top of the first folded edge 81 and the side of the stopper 4 can be provided with anti-slip patterns or anti-slip bumps to further increase the friction force, and an elastic mechanism such as a coil spring is directly provided on the first folded edge 81 and the stopper 4, so that the first folded edge 81 keeps a state of tendency toward the stopper 4 to form an effect of clamping the door bottom, or a screw hole can be directly formed on the movable locking hook 8, and butted and installed under the door by mounting bolts.
