[0003] With the increasing enrichment of cultural life, people have higher and higher requirements for enthusiasm in performances, and higher and higher requirements for theaters. In order to make performing arts produce extraordinary special effects, many modern large-scale performance venues have installed a variety of stage machinery and equipment, which play the role of finishing touch and genius in the stage performances of the repertoire.
[0004] When performing concerts in theaters, the huge stage space diffuses and absorbs most of the music energy, especially when performing and singing without amplification. The music power received by the audience is negligible, and the music effect is greatly reduced. In order to achieve the ideal sound effect and sound pressure in the audience, it is necessary to build an anti-sound cover on the stage to increase the reverberation time, beautify the timbre, enhance the performance effect, and increase the early reflected sound, so that the sound is reflected forward to the audience instead of disappearing into the space above the stage, so that the audience can enjoy the beautiful sound in the concert hall in the large theater. Because the use of anti-sound covers is highly targeted, they are generally used in unplugged concerts, symphonies, choruses and other environments.
[0005] However, the soundproofing panels of the acoustic shield need to be folded up when not in use. The soundproofing panels of large theaters are large in size, difficult to fold up, and inconvenient to store. They are also inconvenient to take out and install when performing again, which wastes a lot of manpower, material resources and storage space, and is very troublesome.
[0006] Therefore, in order to solve the above problems, it is necessary for us to design a reasonable folding stage sound-reflecting cover. Summary of the invention

[0026] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.
[0027] The soundproofing panels of the acoustic shield need to be folded up when not in use. The soundproofing panels of large theaters are large in size, difficult to fold up, and inconvenient to store. They are also inconvenient to take out and install for the next performance, which wastes a lot of manpower, material resources and storage space, and is very troublesome.
[0028] Embodiment 1: Figures 1 to 3 As shown, it is only one of the embodiments of the present invention, a foldable stage sound-reflecting cover plate, comprising a fixing frame 3 and a first beam 1 and a second beam 2 connected to the fixing frame 3, the first beam 1 is connected to a first cover plate 11 at one end away from the fixing frame 3, the second beam 2 is connected to a second cover plate 21 at one end away from the fixing frame 3, the first cover plate 11 is connected to the second cover plate 21 through a connecting plate 4, connecting buckles 5 are arranged between the first beam 1 and the first cover plate 11, between the second beam 2 and the second cover plate 21, between the first cover plate 11 and the connecting plate 4, and between the second cover plate 21 and the connecting plate 4, a winch 12 and a steel wire rope 13 connected to the winch 12 are arranged on one side of the first beam 1 close to the connecting plate 4, and the other end of the steel wire rope 13 is connected to a fixing anchor 211 arranged at one end of the second cover plate 21 away from the connecting plate 4.
[0029] In the present invention, the first beam 1 and the second beam 2 are connected to the fixing frame 3, the first cover plate 11 on the first beam 1 and the second cover plate 21 on the second beam 2 are connected through a connecting plate 4, and connecting buckles 5 are provided between the first beam 1 and the first cover plate 11, between the second beam 2 and the second cover plate 21, between the first cover plate 11 and the connecting plate 4, and between the second cover plate 21 and the connecting plate 4. It should be noted that the connecting buckle 5 is a 360° rotating connecting hinge or a 360° rotating rotating buckle or other connecting parts that can rotate 360°, and the connecting buckle 5 rotates around the connection at both ends, referring to Figure 3 That is to say, the first cover plate 11 rotates around the connection with the first beam 1, the second cover plate 21 rotates around the connection with the second beam 2, the first cover plate 11 rotates around the connection with the connecting plate 4, and the second cover plate 21 rotates around the connection with the connecting plate 4.
[0030] The first cover plate 11, the second cover plate 21 and the connecting plate 4 together form a sound-reflecting functional part for performing stage sound reflection.
[0031] When anti-sound is needed, the surfaces of the first cover plate 11, the second cover plate 21 and the connecting plate 4 are in a straight line for sound reflection on the stage. Figure 1 .
[0032] Reference Figure 2 When the anti-sound cover plate is used up and needs to be folded up, it is only necessary to start the winch 12 to pull the wire rope 13, and the wire rope 13 drives the second cover plate 21 away from the side of the connecting plate 4 to fold inwards. Similarly, the connecting plate 4 drives the first cover plate 11 to fold outwards. At this time, the second beam 2 rises toward the first beam 1 until the first cover plate 11 is completely located above the first beam 1 and the second cover plate 21 is completely located below the second beam 2. At this time, the anti-sound cover plate is folded up, and the height of the anti-sound cover plate is only the height of the connecting plate 4. The second beam 2 and the entire anti-sound cover plate rise to the height of the first beam 1, and are suspended above the stage without occupying the stage space.
[0033] If it is necessary to use the anti-sound cover again, the winch 12 only needs to release the wire rope 13, and the second beam 2 will fall down under gravity. At this time, the first cover plate 11 and the second cover plate 12 will be folded outward until they fall to the point where the surfaces of the first cover plate 11, the second cover plate 21 and the connecting plate 4 are in a straight line. When the second beam 2 is subjected to tension, it stops falling. At this time, the height of the anti-sound cover plate is the sum of the length of the first cover plate 11, the length of the second cover plate 21 and the height of the connecting plate 4.
[0034] In short, the winch 12 tightens the wire rope 13, the second beam 2 rises and approaches the first beam 1, the anti-sound cover is retracted, the winch 12 loosens the wire rope 13, the second beam 2 descends and moves away from the first beam 1, and the anti-sound cover is opened.
[0035] The foldable stage sound-reflecting cover plate of the present invention has a simple structure, can be folded to be opened and folded, opened when needed, and folded and folded above the stage after use, does not occupy stage space, can be unfolded again at any time, and has good stability.
[0036] Embodiment 2, still as Figures 1 to 3 The figure is only one embodiment of the present invention. In order to make the folding stage sound-reflecting cover of the present invention have a better folding and unfolding effect and a higher stability, the present invention also has the following designs:
[0037] First, a through hole 22 is provided on the second beam 2 to facilitate the passage of the steel wire rope 13, and the distance between the through hole 22 and the second cover plate 2 is the same as the distance between the fixed anchor 211 and the second beam 2. That is to say, when the second cover plate 2 is folded up to the bottom of the second beam 2, the fixed anchor 211 is just located at the lower exit of the through hole 22.
[0038] Then, the number of the first beam 1 and the second beam 2 is at least one, that is, there can be multiple layers of the first beam 1 and the second beam 2, and the first beam 1 and the second beam 2 are alternately arranged from top to bottom, and another first beam 1 is arranged under the second beam 2.
[0039] In this way, one end of the first cover plate 11 away from the connecting plate 4 is connected to one end of the second cover plate 21 away from the connecting plate 4 through the connecting buckle 5 .
[0040] In addition, the fixing frame 3 is provided with a slide groove for facilitating the sliding of the first beam 1 and the second beam 2, and the slide groove is vertically extended, so that the first beam 1 and the second beam 2 can slide up and down to unfold and fold the anti-sound cover plate.
[0041] Then, a first limiting pad 31 connected to the first beam 1 is provided on a side of the fixing frame 3 away from the first cover plate 11 .
[0042] The first limiting pad 31 allows the first beam 1 and the fixing frame 3 to be vertically arranged.
[0043] Similarly, a second limiting pad 32 connected to the second beam 2 is provided on a side of the fixing frame 3 away from the second cover plate 21 .
[0044] The second limiting pad 32 enables the second beam 2 and the fixing frame 3 to be vertically arranged.
[0045] It should be noted that the length of the connecting plate 4 is not less than the sum of the width of the first beam 1 and the width of the second beam 2. In fact, when the anti-sound cover is folded, the distance between the first cover plate 11 at the upper end of the first beam 1 and the second cover plate 21 at the lower end of the second beam 2 is just the length of the connecting plate 4. Generally speaking, a space for the hoist 12 is required to be reserved between the first beam 1 and the second beam 2 to avoid the hoist 12 being clamped and unable to release the wire rope 13, resulting in the anti-sound cover being unable to be unfolded.
[0046] The foldable stage sound-reflecting cover plate of the present invention has a simple structure, can be folded to be opened and folded, opened when needed, and folded and folded above the stage after use, does not occupy stage space, can be unfolded again at any time, and has good stability.
[0047] The present invention is not limited to the above specific implementations, and the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made to the above implementations based on the technical essence of the present invention shall be included in the protection scope of the present invention.
