[0025] The present invention will be further described in detail below with reference to embodiments:

[0026] like Figures 1-5 As shown, this utility model provides a screen protection device, including an outer frame 1, with mounting holes 2 symmetrically opened through the four corners of the outer frame 1, a protective mechanism 3 at the front end of the outer frame 1, a fixing mechanism 4 inside the outer frame 1, and a screen 5 inside the fixing mechanism 4.

[0027] The two ends of screen 5 match the interior of frame 48 and are movably installed.

[0028] In this solution, the mounting holes 2 at the four corners of the outer frame 1 make it easy to install the outer frame 1 and the screen 5 in a suitable position in the subway, so that the screen 5 can be used normally.

[0029] like Figure 3 As shown, the protective mechanism 3 includes a groove 31, which is formed on the front end surface of the outer frame 1. A limiting magnet 32 ​​is fixedly provided on the inner side of the groove 31. Ear slots 33 are symmetrically formed on both sides of the groove 31. Screw holes 34 are formed at the bottom of the ear slots 33. A baffle 35 is movably provided at the front end of the outer frame 1. Ear plates 36 are symmetrically fixedly installed at both ends of the baffle 35. A bolt 37 is movably inserted into the middle of the ear plate 36. A limiting magnet 38 is fixedly connected to the rear end of the baffle 35.

[0030] The limiting magnet 32 ​​and the limiting magnet 38 are magnetically connected, and the baffle 35 is made of transparent material.

[0031] The ear plate 36 fits into the ear groove 33 and is movably installed, and the bolt 37 is threadedly connected to the screw hole 34.

[0032] In this solution, since screen 5 is easily damaged by accidental touch in public places or environments with many people, the transparent baffle 35 can effectively prevent such situations from occurring, providing all-round protection for screen 5, extending the service life of screen 5, and ensuring the normal operation of the device.

[0033] As shown Figures 4-5 in Figure, the fixing mechanism 4 includes an installation groove 41 which is symmetrically arranged on the upper and lower inner walls of the outer frame 1. A double-shaft motor 42 is fixedly installed in the middle of the upper installation groove 41. Both sides of the double-shaft motor 42 are drivingly connected with a lead screw 43. Both sides inside the outer frame 1 are movably installed with a moving plate 44. A guide rod 45 is movably installed inside the lower installation groove 41. A threaded plate 46 is fixedly installed at the upper end of the moving plate 44. A guide plate 47 is fixedly installed at the lower end of the moving plate 44. A clamping frame 48 is fixedly installed on the inner side of the moving plate 44. Soft pads 49 are symmetrically and fixedly installed at both the upper and lower ends on the inner side of the outer frame 1.

[0034] The outer part of the lead screw 43 is threadedly installed with the middle part of the threaded plate 46.

[0035] The outer part of the guide rod 45 is slidably connected with the middle part of the guide plate 47.

[0036] The clamping frame 48 is in a "C" shape, and a rubber pad is adhesively bonded to the inner wall of the clamping frame 48.

[0037] In this solution, the soft pads 49 provided can protect the upper and lower ends of the screen 5, and the rubber pads provided on the inner wall of the clamping frame 48 can protect the two ends of the screen 5, thereby avoiding damage to the outside of the screen 5. By sliding the guide plate 47 on the guide rod 45, the smoothness of the movement of the moving plate 44 can be improved.

[0038] Next, the working principle of the screen protection device will be specifically described.

[0039] As Figures 1-5 shown, when the screen protection device is in use, first, the screen 5 can be placed inside the outer frame 1, and the upper and lower ends of the screen 5 are made to contact the upper and lower soft pads 49. Subsequently, the double-shaft motor 42 can be started. The double-shaft motor 42 drives the lead screws 43 on both sides to rotate, causing the lead screws 43 to gradually bring the threaded plates 46 threadedly installed on both sides closer. The threaded plates 46 drive the moving plates 44 to approach each other through the cooperation of sliding on the guide rod 45 by the guide plates 47, so that the clamping frames 48 on both sides contact and clamp the two ends of the screen 5, thereby completing the installation of the screen 5. Subsequently, the baffle 35 can be placed in the groove 31, and the magnetic attraction effect between the two groups of limit magnets is used to facilitate the limit of the baffle 35. At the same time, the ear plates 36 on both sides will be embedded in the ear grooves 33, and then the threaded effect between the bolts 37 and the screw holes 34 can be used to reinforce the baffle 35, thus completing the installation of the baffle 35. The baffle 35 can be used to protect the screen 5 and prevent the exposed screen 5 from being damaged.

[0040] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
