[0028] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0029] Reference Figure 1 and Figure 2 The utility model provides an embodiment: a self-closing safety protection door for a door opening, comprising an outer frame 1, the upper and lower sides of the inner wall of the outer frame 1 are fixedly connected with a rotating leaf 3, the bottom walls of the two rotating leaves 3 are rotatably connected with a connecting shell 4, the adjacent sides of the two connecting shells 4 are provided with a snap-fitting groove 5, the middle part of the inner wall of the outer frame 1 is fixedly connected with a fixing plate 6, the front and rear sides of the fixing plate 6 are provided with a protective plate 9, the left and right sides of the top walls of the two protective plates 9 are fixedly connected with a connecting plate 7, and the top walls of the plurality of connecting plates 7 are threaded with a threaded rotating Button 8, the bottom ends of multiple threaded knobs 8 are all threadedly connected to the four corners of the top wall of the fixing plate 6, the two protective plates 9 are respectively engaged with the corresponding engaging grooves 5 on the far side, the left and right ends of the rear side of the top wall of the outer frame 1 are fixedly connected with steel bars 13, the left and right ends of the front side of the top wall of the outer frame 1 are fixedly connected with blocking members 11, the two steel bars 13 and the inner walls of the two blocking members 11 are threadedly penetrated with bolts 12, the far ends of the multiple bolts 12 are all threadedly connected with stone walls 16, and the front side of the stone wall 16 is provided with an opening mechanism 2;

[0030] Specifically, the threaded knob 8 is turned to separate the connecting plate 7 from the fixing plate 6, and then the protective plate 9 is turned forward, and the protective plate 9 is pulled to separate it from the corresponding engaging groove 5. This step is simple and easy to perform, and no complicated tools or equipment are required. When the protective plate 9 is damaged, it can be quickly replaced, which not only ensures the effectiveness of safety protection, but also facilitates the recycling of damaged door panels. The design of the protective door also takes into account its flipping requirements in the vertical direction. Through the connection between the steel bars 13, the bolts 12 and the stone wall 16, the protective door can be flipped vertically when needed.

[0031] Reference Figure 1 and Figure 3 The opening mechanism 2 includes a fixed shell 201, the rear side of the fixed shell 201 is fixedly connected to the front side of the stone wall 16, a servo motor 202 is fixedly connected to the left side of the inner wall of the fixed shell 201, a rotating column 203 is fixedly connected to the output end of the servo motor 202, and steel cables 204 are fixedly connected to the left and right sides of the outer wall of the rotating column 203, and the bottom ends of the two steel cables 204 are respectively fixedly connected to the outer walls of the corresponding blocking member 11, and the left and right ends of the front side of the fixed shell 201 are fixedly connected to the supporting shells 205, and the inner walls of the two supporting shells 205 are rotatably connected to the pulleys 206;

[0032] Specifically, the rotation of the servo motor 202 drives the rotation of the rotating column 203. The rotating column 203 is an important component connecting the servo motor 202 and the steel cable 204. Its rotation directly determines the winding and releasing of the steel cable 204. During the rotation of the rotating column 203, the steel cable 204 is gradually wound up. During this process, the bottom end of the steel cable 204 always maintains a fixed connection with the barrier 11. When the steel cable 204 is wound up, the barrier 11 will drive the protective door to move together. The protective door rotates with the top bolt 12 and the steel bar 13 as a fulcrum. This process is both stable and reliable.

[0033] Reference Figure 1 , Figure 2 and Figure 3 The left end of the front side of the stone wall 16 is fixedly connected with a control switch 17, and the control switch 17 is electrically connected to the servo motor 202; the front side of the control switch 17 is provided with a protective shell 18, and the rear side of the protective shell 18 is rotatably connected to the front side of the stone wall 16 through a hinge; the internal size of the stone wall 16 matches the external size of the outer frame 1;

The internal size of the stone wall 16 is matched with the external size of the outer frame 1, so that the opening and closing of the protective door are convenient.

[0035] Reference Figure 2 A warning plate 10 is fixedly installed at the middle of the front side of the two protective plates 9; a rubber tube 14 is fixedly connected to the far ends of the two blocking members 11; and a plurality of baffles 15 are fixedly connected to the bottom wall of the outer frame 1 at equal intervals;

[0036] Specifically, the warning plate 10 provides a warning function, the two rubber tubes 14 facilitate protection of the blocking member 11, and the plurality of baffles 15 prevent the protective plate 9 from flipping backwards.

[0037] Working principle: When starting to disassemble, by turning a plurality of threaded knobs 8, the protective plate 9 can be rotated by the turning page 3, and by rotating the protective plate 9 forward and pulling the protective plate 9 at the same time, the protective plate 9 is separated from the corresponding engaging groove 5, thereby completing the purpose of disassembling the protective plate 9, so that the protective plate 9 can be replaced, and then it is convenient to recycle the damaged door panel, thereby reducing the use cost of the protective door, and the protective door can be flipped in the vertical direction through the connection between the steel bar 13, the bolt 12 and the stone wall 16, and by starting the servo motor 202, the rotating column 203 starts to rotate to complete the winding of the steel cable 204, and the bottom end of the steel cable 204 is fixedly connected to the barrier 11, so that the protective door rotates through the top bolt 12 and the steel bar 13 as a fulcrum, thereby completing the purpose of automatic opening.

[0038] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention.
