[0007] Preferably, the lifting assembly includes a threaded block for driving the scraper to move, the interior of the empty slot is rotatably connected to a reciprocating screw for moving the threaded block, and a motor for driving the reciprocating screw to rotate is installed on the top of the protective frame.

[0008] Preferably, the sealing assembly includes a sealing plate for covering the empty groove, a circular clamping hole is provided on one side of the sealing plate, a clamping column for inserting into the clamping hole is slidably connected inside the protective frame, a movable plate for driving the clamping column to move is installed at one end of the clamping column, and a spring for driving the movable plate to move is installed on one side of the protective frame.

[0009] Preferably, a through slot is provided on one side of the protection frame, and a convex plate is slidably connected inside the through slot to facilitate workers to move the sealing plate, and the length of the convex plate is greater than the length of the through slot.

[0010] In summary, due to the adoption of the above technical solution, the beneficial effects of the utility model are:

[0011] In the present application, when the multimedia display screen needs to be cleaned, the staff first grasps the movable plate to move the card column out of the card hole, and then grasps the convex plate to move the sealing plate out of the empty groove, so that the sealing plate will no longer block the scraper. At this time, the staff can turn on the motor, and the motor will drive the reciprocating screw to rotate. The reciprocating screw will drive the scraper to move through the thread block through the thread, and the scraper will scrape and clean the dust on the display screen to prevent the dust from affecting the clarity of the display screen.

[0017] 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 of 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.

[0018] See also Figure 1-3 , the utility model provides a technical solution:

[0019] Embodiment 1:

[0020] like Figure 1-3As shown, a multimedia display screen for exhibitions includes a protective frame 1, a display screen 2 for displaying materials is installed inside the protective frame 1, a scraper 3 for cleaning dust on the display screen 2 is slidably connected to one side of the display screen 2, an empty slot 4 is provided inside the protective frame 1, a lifting component for driving the scraper 3 to move is installed inside the empty slot 4, a sealing component for preventing dust from entering the empty slot 4 is installed on the protective frame 1, and a slope 15 for convenient dust removal is provided on one side of the protective frame 1.

[0021] Embodiment 2:

[0022] The technical solution is basically the same as that of the first embodiment, except that Figure 3 As shown, the lifting assembly includes a threaded block 5 for driving the scraper 3 to move, the number of the threaded blocks 5 is set to two and the two threaded blocks 5 are arranged in a mirror-symmetrical manner with the scraper 3 as the center, the internal rotation of the empty groove 4 is connected to a reciprocating screw 6 for moving the threaded block 5, and a motor 7 for driving the reciprocating screw 6 to rotate is installed on the top of the protective frame 1.
