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.

[0026] Specific embodiment 1: Please refer to Figure 1-6 The utility model provides a mobile display device for intelligent automatic cost calculation, including a bottom plate 1 and a display screen body 5. A fixing column 2 is welded and fixed at the top of the bottom plate 1. A fixing mechanism for conveniently fixing the display screen body 5 is provided between the fixing column 2 and the display screen body 5. A protective mechanism for conveniently protecting the display screen body 5 is provided at the top of the fixing column 2. The protective mechanism includes a limiting component, a protective cloth 6, a shell 3, a movable shaft 10, a fixing ring 11, a second hook 4 and a torsion spring 12. The shell 3 is welded and fixed at the top position of the fixing column 2. The second hook 4 is welded and fixed on one side of the shell 3. The movable shaft 10 is movably embedded in the center position inside the shell 3. The fixing ring 11 is welded and fixed on the outside of the movable shaft 10. There are two fixing rings 11, which are symmetrically fixed at the two sides of the movable shaft 10. The torsion spring 12 is welded and fixed between the fixing ring 11 and the inner wall of the shell 3. The protective cloth 6 is wound and fixed on the outside of the movable shaft 10. One side of the protective cloth 6 is movably extended to the outside of the shell 3. The limiting component is between the bottom plate 1 and the protective cloth 6.

[0027] The limiting assembly includes an elastic rope 7, a first hook 9 and a rectangular ring 8. The elastic rope 7 is adhesively fixed to the bottom end of the protective cloth 6, the first hook 9 is wound and fixed to the bottom end of the elastic rope 7, and the rectangular ring 8 is welded and fixed to the top position of the bottom plate 1. When idle, the protective cloth 6 is pulled out to cover the outside of the display screen body 5. When the protective cloth 6 is pulled out, the movable shaft 10 is driven to rotate, so that the torsion spring 12 is tightened, and then the elastic rope 7 is stretched until the first hook 9 is hung on the rectangular ring 8, so that the position of the protective cloth 6 is fixed to protect the display screen body 5. When in use, the first hook 9 is separated from the rectangular ring 8, and then the torsion spring 12 is reset, driving the movable shaft 10 to rotate, and the protective cloth 6 is rewound around the outside of the movable shaft 10, and then the first hook 9 is hung on the second hook 4; the rectangular ring 8 is located on the side of the display screen body 5 close to the fixed column 2, so that the bottom of the protective cloth 6 is offset toward the rear side when covering, so that the protective cloth 6 can be attached to the surface of the display screen body 5, firmly protecting the surface of the display screen body 5 from dust accumulation.

[0028] The fixing mechanism includes a hollow rod 13, a groove body 16, a screw rod 14 and an extrusion ring 15. The hollow rod 13 is welded and fixed on one side of the fixing column 2. The groove body 16 is opened at the top of the hollow rod 13. The screw rod 14 is inserted into the mounting frame of the display screen body 5 through a thread. The extrusion ring 15 is welded and fixed around the outside of the screw rod 14. When in use, the mounting frame of the display screen body 5 is inserted into the hollow rod 13. At this time, the screw rod 14 slides into the groove body 16, and then the screw rod 14 is rotated to make the screw rod 14 move downward, driving the extrusion ring 15 to move downward until the top position of the hollow rod 13 is squeezed, and the position of the display screen body 5 is fixed by friction. In this way, it is convenient to install multiple display screen bodies 5 for coordinated use during use to increase the display area, so as to ensure that a large amount of information can be fully displayed.

[0029] Working principle: when the display screen is idle, the protective cloth 6 is pulled out to cover the outside of the display screen body 5. When the protective cloth 6 is pulled out, the movable shaft 10 is driven to rotate, so that the torsion spring 12 is tightened, and then the elastic rope 7 is stretched until the first hook 9 is hung on the rectangular ring 8, so that the position of the protective cloth 6 is fixed to protect the display screen body 5. When in use, the first hook 9 is separated from the rectangular ring 8, and then the torsion spring 12 is reset, driving the movable shaft 10 to rotate, and the protective cloth 6 is rewound around the outside of the movable shaft 10, and then the first hook 9 is hung on the second hook 4; when in use, the mounting frame of the display screen body 5 is inserted into the hollow rod 13, and the screw rod 14 slides into the groove body 16, and then the screw rod 14 is rotated to make the screw rod 14 move downward, driving the extrusion ring 15 to move downward until the top position of the extruded hollow rod 13 is pressed, and the position of the display screen body 5 is fixed by friction, so that when in use, it is convenient to install multiple display screen bodies 5 for coordinated use, increase the display area, and ensure that the information can be fully displayed when there is a lot of information.

[0030] Specific embodiment 2: Based on the specific embodiment 1, the difference is that please refer to Figure 7-Figure 8 , the protective cloth 6 is set to two partially overlapping ones in the middle, corresponding to the display screen main body 5 on the left and right sides respectively. When only the display screen main body 5 on one side is put into use, the idle display screen main body 5 on the other side can be protected by the protective cloth 6. Correspondingly, there are two movable shafts 10, and two positioning rings 17 are fixedly connected to the movable shafts 10 inside the shell 3 respectively. The two ends of each movable shaft 10 are rotatably connected to the inner wall of the shell 3 and the positioning ring 17 respectively, and the two positioning rings 17 are staggered to ensure that the two protective cloths 6 are in the front and rear positions, and there is a small amount of overlap in the middle, so that when the two protective cloths 6 are put into use, no gap will be generated in the middle. It should be noted that fixing rings 11 and torsion springs 12 can also be set on both sides of the movable shaft 10 to improve the rotation stability of the movable shaft 10.

[0031] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.
