[0021] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention and are not used to limit the present invention.

[0022] Example: Figures 1 to 3 As shown, the utility model is a folding structure hanging hole cover with a space-saving structure, including a cover body 12, which is hinged by two square plates. The cover body 12 is installed at the hanging hole 1, and a rotating shaft 11 is fixedly provided at the bottom end of the cover body 12. The rotating shaft 11 is rotatably set at the hanging hole 1, and a motor 14 is fixedly installed at one end of the hanging hole 1, and the output end of the motor 14 is fixedly connected to one end of the rotating shaft 11.

[0023] The motor 14 is a reduction motor. When it is working, it drives the rotating shaft 11 to rotate, thereby driving the cover body 12 to rotate together. The two square plates can only rotate 180 degrees toward the side away from the rotating shaft 11. During the rotation of the cover body 12, you can choose to block the other square plate when the cover body 12 rotates slowly, so that the two square plates are overlapped together. You can also pause the motor 14 when the cover body 12 rotates to 45-60 degrees, and then manually adjust it to make the two square plates overlap, and then start the motor 14 to make it work. The motor 14 is controlled by an existing controller and will not be described in detail here.

[0024] A support plate 15 is fixedly mounted on the inner wall of one side of the hanging hole 1, and the cover body 12 is attached to the top surface of the support plate 15. The support plate 15 is arranged on the side away from the rotating shaft 11, thereby supporting the support plate 15 and enhancing its stability when the cover is closed. A U-shaped frame 2 is placed around the top surface of the hanging hole 1. The U-shaped frame 2 and the cover body 12 are connected by a plug rod 10. The space formed by the U-shaped frame 2 and the cover body 12 can enhance stability during maintenance and save space within the hanging hole 1.

[0025] The bottom end of the U-shaped frame 2 is equipped with a universal wheel 4, and the opposite back surfaces of the U-shaped frame 2 are symmetrically equipped with mounting plates 5, which are threadedly connected to screws 6, and the bottom ends of the screws 6 are rotatably equipped with suction cups 7. The universal wheels 4 make it easy to move the U-shaped frame 2. When in use, it can be moved to the side of the hanging hole 1, and then removed from the side of the hanging hole 1 after use.

[0026] There is a gap between the four sides of the cover body 12 and the side wall of the hanging hole 1, and warning signs 13 are pasted on the four sides of the surface of the hanging hole 1. The gap facilitates the rotation of the cover body 12, and the warning signs 13 can remind people of the position of the hanging hole 1.

[0027] The top surface of the cover body 12 is located above the top surface of the hanging hole 1, and mounting holes 9 are symmetrically opened on the side surfaces of the cover body 12 and the side surfaces of the U-shaped frame 2. The mounting holes 9 are symmetrically opened on the two square plates, and the mounting holes 9 on the U-shaped frame 2 pass through the U-shaped frame 2. A connecting block 8 is magnetically attracted to the side of the U-shaped frame 2 away from the cover body 12. A plug rod 10 is fixedly connected to the side of the connecting block 8 facing the cover body 12. The plug rod 10 passes through the mounting hole 9 on the U-shaped frame 2 and is inserted into the mounting hole 9 on the cover body 12.

[0028] After the U-shaped frame 2 is moved to the side of the hanging hole 1 , the insertion rod 10 can be passed through the mounting hole 9 so that it is clamped in the mounting hole 9 on the square plate. At this time, the connecting block 8 is magnetically attached to the surface of the U-shaped frame 2 .

[0029] The U-shaped frame 2 is provided with a through hole 3 for easy observation, and the rotating shaft 11 is installed at a position close to the notch of the U-shaped frame 2. The suction cup 7 is located on both sides of the universal wheel 4, and when the top surface of the screw 6 is in contact with the top surface of the mounting plate 5, the suction cup 7 is adsorbed on the ground.

[0030] When the U-shaped frame 2 is moved to the side of the hanging hole 1, the screw 6 can be rotated to drive the suction cup 7 to move downward until the suction cup 7 is adsorbed on the ground (the ground in this application changes according to actual conditions and may be the surface of the equipment), so as to enhance the stability of the U-shaped frame 2 during use.

[0031] During operation, the cover body 12 rotates under the action of the rotating shaft 11, and the two square plates on the cover body 12 can be folded, and then the U-shaped frame 2 is pushed to the hanging hole 1, and the U-shaped frame 2 is clamped with the cover body 12 through the insertion rod 10 on the U-shaped frame 2, so that the U-shaped frame 2 and the cover body 12 form a safe space, and the U-shaped frame 2 is equipped with universal wheels 4 and suction cups 7. When in use, the suction cups 7 are adsorbed on the ground to enhance stability, and the universal wheels 4 are set to make movement more convenient.

[0032] Finally, it should be noted that the above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art will be able to modify the technical solutions described in the aforementioned embodiments or replace some of the technical features therein with equivalents. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
