[0026] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0027] See attached document Figure 1 - Appendix Figure 4 The present invention provides a display screen cover and an LED display screen, including a positioning base 1, which is a circular structure. A base plate 2 is fixedly connected to the top of the positioning base 1, and a support rod 3 is fixedly connected to the top of the base plate 2.

[0028] LED display screen body 4, with a positioning plate 5 fixedly connected to the rear side of the LED display screen body 4, and the positioning plate 5 fixedly connected to the top of the support rod 3;

[0029] The shielding mechanism is located on both sides of the LED display screen body 4 and is used to protect the LED display screen body 4.

[0030] The shielding mechanism includes two shielding films 6, which are respectively located on both sides of the LED display screen body 4;

[0031] In this embodiment, the user starts the drive motor 12 to work, which causes the shielding mechanism to work, thereby controlling the shielding membrane 6, so that the two shielding membranes 6 are closed or opened, making the structure work more efficient.

[0032] To achieve the purpose of protecting the LED display screen, this device adopts the following technical solution: The shielding mechanism also includes two positioning frames 7, both of which are located on the rear side of the LED display screen body 4. Each positioning frame 7 has a winding wheel 8 embedded inside it. Two shielding films 6 are respectively fixedly fitted onto the outside of the two winding wheels 8, with their outer ends extending to the outside of the two positioning frames 7. The shielding mechanism also includes two transmission rods 9, each embedded inside the two positioning frames 7 and movably connected to them via rolling bearings. The two transmission rods 9 are respectively fixedly embedded inside the two winding wheels 8. Each positioning frame 7 has a movable wheel 10 at its bottom, and a pull rope 11 is fitted onto the outside of each movable wheel 10. The two movable wheels 10 are respectively fixedly fitted onto the outside of the two transmission rods 9. The structure also includes a drive motor 12, a support plate 13 fixedly connected to the rear side of the positioning base 1, the drive motor 12 is located on the top of the support plate 13, the output end of the drive motor 12 is fixedly connected to a drive shaft 14, a positioning wheel 15 is fixedly sleeved on the outside of the drive shaft 14, two pull ropes 11 are both wrapped around the outside of the positioning wheel 15, two pulleys 16 are provided on the top of the support plate 13, the two pulleys 16 are respectively sleeved on the inside of the two pull ropes 11, the top and bottom of the LED display body 4 are both fixedly connected to a fixing plate 18, the outside of the two fixing plates 18 are both fixedly connected to a spring 19, the outer ends of the two springs 19 are both fixedly connected to a moving frame 21, the front side of the LED display body 4 is provided with two moving strips 20, the two moving strips 20 are respectively fixedly connected to two shielding films 6, and the two moving strips 20 are respectively fixedly connected to two moving frames 21;

[0033] The drive motor 12 drives the drive shaft 14 to rotate. The rotation of the drive shaft 14 drives the positioning wheel 15 and the pull rope 11 to rotate. The rotation of the pull rope 11 causes the pull rope 11 to retract. The retraction of the pull rope 11 drives the movable wheel 10 to rotate. The rotation of the movable wheel 10 drives the drive rod 9 and the winding wheel 8 to rotate. The rotation of the winding wheel 8 drives the shielding film 6 to rotate, causing the shielding film 6 to extend. At this time, the spring 19 rebounds and tightens, causing the movable frame 21 and the movable bar 20 to move, causing the shielding film 6 to close. Similarly, the drive motor 12 is started to work in the opposite direction, causing the positioning wheel 15 to rotate in the opposite direction, thereby tightening the pull rope 11. The tightening of the pull rope 11 drives the drive rod 9 and the winding wheel 8 to rotate in the opposite direction, thereby causing the shielding film 6 to extend into the positioning frame 7, so as not to shield the LED display screen body 4.

[0034] In order to achieve the purpose of structural support, the device adopts the following technical solution: a support frame 17 is fixedly connected to the top of the support plate 13, and the support frame 17 is sleeved on the outside of the transmission shaft 14 and is movably connected to the transmission shaft 14 through a rolling bearing.

[0035] The usage process of this utility model is as follows: By starting the transmission motor 12, the blocking mechanism is activated, thereby controlling the blocking film 6, causing the two blocking films 6 to close or open, thus improving the working efficiency of the structure. The operation of the transmission motor 12 drives the transmission shaft 14 to rotate, which in turn drives the positioning wheel 15 and the pull rope 11 to rotate. The rotation of the pull rope 11 causes the pull rope 11 to retract, which in turn drives the movable wheel 10 to rotate. The rotation of the movable wheel 10 drives the transmission rod 9 and the winding wheel 8 to rotate, which in turn drives the blocking film 6 to rotate, causing the blocking film 6 to extend. At this time, the spring 19 rebounds and tightens, causing the movable frame 21 and the movable bar 20 to move, thus closing the blocking film 6. Similarly, starting the transmission motor 12 in the opposite direction causes the positioning wheel 15 to rotate in the opposite direction, thereby tightening the pull rope 11. The tightening of the pull rope 11 drives the transmission rod 9 and the winding wheel 8 to rotate in the opposite direction, thus causing the blocking film 6 to extend into the positioning frame 7, thereby not blocking the LED display screen body 4.

[0036] The above description is merely a preferred embodiment of this utility model. Any person skilled in the art may modify this utility model or modify it into an equivalent technical solution using the technical solutions described above. Therefore, any simple modifications or equivalent substitutions made based on the technical solutions of this utility model are within the scope of protection claimed by this utility model.
