Obviously, the described embodiment is a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment 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.

[0029] The utility model is further described below in conjunction with embodiments.

[0030] Example: Refer to the attached Figure 1-4 As shown in , a demonstration board for organizing sports events includes two foldable mounting plates 100, a display screen 400 is fixedly installed inside the mounting plates 100, a belt body 200 is connected between the middle parts of the two mounting plates 100, and an extension part 210 is fixedly installed at the end of the belt body 200; a mounting block 130 is installed at the bottom of the mounting plate 100, a capsule 131 is arranged inside the mounting block 130, and the outer wall of the capsule 131 is fixedly connected to the extension part 210 of the belt body 200, and when the belt body 200 is stretched, the capsule 131 will be stretched; the capsule 131 is connected to the air outlet 103 opened on one side of the display screen 400 through the connecting groove inside the mounting plate 100. Specifically, when the demonstration board is in use, the two mounting plates 100 are in an unfolded state, and both display screens 400 can be written on, so that a good demonstration can be performed;

[0031] It should also be noted that a mounting groove 102 is provided on the inner side of the mounting plate 100, and the mounting groove 102 is elastically connected to the metal block 300 through a spring 310; a metal rod 120 is elastically connected to the corresponding position of the other mounting plate 100, and when the metal rod 120 contacts the metal block 300, the display screen 400 maintains electrical connection with the power supply arranged on the mounting plate 100, so that when the mounting plate 100 is in the unfolded state, the metal rod 120 located on different mounting plates 100 can contact the metal block 300, and connect the display screen 400 with the power supply arranged on the mounting plate 100, so as to facilitate the normal use of the display screen 400, and when not in use, the two mounting plates 100 need to be folded, and at this time the metal rod 120 is no longer in contact with the metal block 300, and the display screen 400 is powered off, so as to improve the stability of the demonstration board.

[0032] A groove is opened in the middle of the mounting plate 100, and the display screen 400 is installed inside the groove; and a magnetic block 110 is fixedly installed on the upper outer wall of the mounting plate 100, and the magnetic blocks 110 located on two different mounting plates 100 are magnetically adsorbed. Specifically, when the two mounting plates 100 are in a folded state, the two magnetic blocks 110 can maintain stable magnetic adsorption, and sealing gaskets are laid on the outer side of the top surface of the mounting plate 100; when the belt body 200 is folded, the sealing gaskets located on different mounting plates 100 can maintain contact, and when the magnetic block 110 maintains magnetic adsorption, the sealing gaskets on different mounting plates 100 can contact, thereby realizing the sealing of the display screen 400, realizing the protection of the display screen 400, and preventing external dust from falling on the surface of the display screen 400.

[0033] An escape groove 101 is provided on the upper side of the inner end of the mounting plate 100; the two mounting plates 100 can rotate around the escape groove 101 and remain connected through the belt body 200, and the magnetic attraction force between the two magnetic blocks 110 is greater than the elastic force of the belt body 200. It should be noted that in order to ensure the stability of the demonstration board in the folded state, the magnetic attraction force between the two magnetic blocks 110 is greater than the elastic force of the belt body 200, so that the stability of the demonstration board in the folded state can be ensured.

[0034] Furthermore, when the display screen 400 is used, it is exposed to the outside air and is easily adhered to dust. Therefore, in the present application, when the two mounting plates 100 are in a folded state, the metal rod 120 and the metal block 300 extend out from the mounting plate 100, causing the belt body 200 to deform and form a placement groove 201. A sliding groove 104 is provided on the lower side of the mounting plate 100, and the extensions 210 at both ends of the belt body 200 slide in the sliding groove 104; and the extensions 210 are made of a hard material. When the mounting plate 100 is folded, the belt body 200 disposed between the middle portions of the two mounting plates 100 will be stretched, as shown in the attached Figure 4As shown in , the belt body 200 will be stretched at this time. First, the extending portion 210 is arranged in cooperation, which will stretch the capsule 131. The corresponding capsule 131 is connected with the air outlet 103 opened on the side of the display screen 400 through the connecting groove, and the air flow is used to effectively clean the surface of the display screen 400. It should be noted that when the folding is completed, the metal rod 120 and the metal block 300 will extend out from the mounting plate 100 and contact the outer wall of the belt body 200. The corresponding placement groove 201 can be used to place a writing pen and simultaneously achieve sealing of the display screen 400.

[0035] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some of the technical features therein by equivalents. These modifications or replacements will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of the present invention.
