Technical Field

[0001] The utility model relates to the technical field of screen protection, in particular to a large screen protection device for a smart exhibition hall. Background Technique

[0002] Smart exhibition halls usually use large screens to display various information, exhibit introductions, interactive experiences, etc., to attract audiences, improve the display effect of exhibits, and increase participation and interactivity. Large screens play multiple important roles in smart exhibition halls. They can not only enrich the exhibition content, enhance the audience experience, but also provide real-time data and better operation management means for exhibition hall managers.

[0003] The large screen protection device for a smart exhibition hall refers to a device used to protect the large screen, which can effectively protect the large screen and enable it to operate safely and stably.

[0004] Chinese Patent Publication No.: CN216539690U published "A Large Screen Protection Device for a Smart Exhibition Hall", which includes a base and a screen body. An installation frame is provided on the top of the base, a cross plate is provided on the top of the installation frame, and a cleaning mechanism is provided inside the installation frame; a dust-proof mechanism is connected between the inside of the base and the inside of the cross plate. The cleaning mechanism includes a stepping motor, a lead screw, a bearing, a moving plate, a fixing plate, a slide bar and a cleaning brush. The dust-proof mechanism includes a driving motor, a rotating shaft, a sprocket, a chain, a rolling roller and a dust-proof cloth. The utility model is a large screen protection device for a smart exhibition hall. By using the cleaning brush to clean the dust attached to the outer surface of the screen body, the cleanliness of the outer surface of the screen body is ensured, and the viewing effect is improved. Therefore, when the screen body is not in use, the dust-proof cloth can avoid dust from affecting the cleanliness of the screen body, improve the protection effect of the screen body, and the dust-proof cloth can prevent damage to the surface of the screen body.

[0005] When the prior art is in use, although the dust attached to the outer surface of the screen body can be cleaned by the cleaning brush to ensure the cleanliness of the outer surface of the screen body and improve the viewing effect, the existing device only protects the screen with a dust-proof cloth. However, the texture of the dust-proof cloth is relatively soft and cannot provide effective protection for the screen in case of bumps or other situations, which easily causes the screen to be damaged due to bumps. At the same time, since there are many flowing people inside the exhibition hall, the flowing people are likely to collide with the device during the playback process. And the existing device lacks a fixing device for the device, so the device is likely to fall due to collision during use, which has a certain impact on the later use safety of the device.

[0034] Specifically, a lifting motor 12 is fixedly installed on one side of the outer surface of the box body 1, and the output shaft of the lifting motor 12 is fixedly connected to the first positive and negative lead screw 2.

[0035] Through the above technical solution, the lifting and lowering of the screen body 4 is controlled by the lifting motor 12.

[0036] Specifically, a support motor 11 is fixedly installed on one side of the outer surface of the bottom plate 3, and the output shaft of the support motor 11 is fixedly connected to the second positive and negative lead screw 302.

[0037] Through the above technical solution, the support motor 11 drives the second lead screw 302 to rotate.

[0038] Specifically, hydraulic presses 8 are provided on one side of multiple reinforcement plates 304 away from the sliding plate 303, and hydraulic rods 9 are fixedly installed at the bottoms of the outer surfaces of the multiple hydraulic presses 8. Support disks 10 are fixedly installed on one side of the multiple hydraulic rods 9 away from the hydraulic presses 8.

[0039] Through the above technical solution, the hydraulic press 8 drives the support disk 10 to descend through the hydraulic rod 9, and the stability of the device is increased through the support disk 10 to prevent the device from tipping over during use.

[0040] Specifically, a protective plate 5 is fixedly installed at the top of the outer surface of the screen body 4, and multiple moving wheels 13 are fixedly installed at the bottom of the outer surface of the bottom plate 3.

[0041] Through the above technical solution, the protective plate 5 protects the top of the screen body 4 to prevent the top of the screen body 4 from being damaged, and the moving wheels 13 facilitate the movement of the device.

[0042] During use, the lifting motor 12 can be started. The lifting motor 12 drives the first lead screw 2 to rotate. While the first lead screw 2 is rotating, the two side sliders 202 can move in opposite directions. While the sliders 202 are moving, they can push the push plate 203, so that the push plate 203 pushes the connecting plate 204 to drive the screen body 4 to rise. Video is played through the screen body 4. After the playing is completed, the lifting motor 12 can be started again to reverse the lifting motor 12. While the lifting motor 12 is rotating, it drives the screen body 4 to descend, so that the screen body 4 is retracted into the interior of the box body 1 to protect the screen body 4 and prevent the screen body 4 from being damaged due to collision. When it is necessary to reinforce the device to prevent it from tipping over, the hydraulic press 8 can be started. The hydraulic press 8 drives the hydraulic rod 9 to extend. While the hydraulic rod 9 is extending, it can drive the support disk 10 to move downward until the support disk 10 contacts the ground, and the stability of the device is increased through the support disk 10. When necessary, the support motor 11 can also be started. The support motor 11 drives the second lead screw 302 to rotate. The second lead screw 302 drives the sliding plate 303 to move in opposite directions. Since the reinforcement plate 304 is fixedly connected to the sliding plate 303, the sliding plate 303 can drive the reinforcement plate 304 to move outside the bottom plate 3 while moving, so as to increase the fixing area of the device and prevent the device from tipping over during use.

[0043] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirits of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
