DETAILED DESCRIPTION

[0023] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0024] In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as a limitation on the present invention.

[0025] Reference Figure 1-Figure 5A mobile auxiliary device for stage lighting and sound, including a box body 1, and also includes: a shock-absorbing moving mechanism, fixed at the bottom of the box body 1, used for shock-absorbing movement of the box body 1; a support plate 2, sliding inside the box body 1, used for placing and supporting the sound; a rotating rod 3, rotating at the bottom of the support plate 2 through a rotating shaft, and the end of the rotating rod 3 is rotatably connected to a fixed plate 4 through a rotating shaft; a piston rod 5, fixed at the end of the fixed plate 4, the surface of the piston rod 5 is slidably connected to a piston cylinder 6, the piston cylinder 6 is fixed inside the box body 1, the surface of the piston cylinder 6 is connected to a telescopic airbag 7 through a pipeline, the telescopic airbag 7 is fixed inside the box body 1, and the telescopic airbag 7 is used to clamp and fix the sound.

[0026] In the utility model, when installing the speaker, firstly, the bottom of the speaker is placed on the top of the support plate 2 in the box 1, and then the support plate 2 is pressed downward by the weight of the speaker itself, and the support plate 2 drives the rotating rod 3 to rotate the fixed plate 4 to move to both sides, and during the movement of the fixed plate 4, the piston rod 5 slides inside the piston cylinder 6, so that the air in the piston cylinder 6 is compressed, and the compressed gas is injected into the telescopic airbag 7 through the pipeline, so that the telescopic airbag 7 expands, and the two sides of the speaker are clamped and fixed by the expansion of the telescopic airbag 7, and the speaker clamp can be ensured to be in the center position.

[0027] Reference Figure 1 The inner bottom wall of the box body 1 is fixedly connected with a deflation mechanism 8, and the surface of the deflation mechanism 8 is connected with a deflation pipe 9. The end of the deflation pipe 9 passes through the fixed plate 4 and is connected to the telescopic airbag 7. The deflation pipe 9 is used to relieve pressure inside the telescopic airbag 7.

[0028] In the utility model, the internal space of the deflation mechanism 8 can be enlarged by rotating the deflation mechanism 8, so that the air pressure in the telescopic airbag 7 is transmitted to the deflation mechanism 8 through the deflation pipe 9. When the internal pressure of the telescopic airbag 7 becomes smaller, the clamping force between the telescopic airbag 7 and the surface of the speaker will also become smaller, thereby facilitating the removal of the speaker.

[0029] Reference Figure 2 A tension spring 10 is fixedly connected between the rotating rod 3, and the tension spring 10 is used to automatically reset the rotating rod 3.

[0030] In the utility model, the tension spring 10 can provide a tension force between the rotating rods 3, so that when there is no heavy object on the support plate 2, the support plate 2 is automatically reset.

[0034] In the utility model, the threaded rod 82 at the end of the deflation cylinder 81 is rotated to move the piston block 83. As the distance between the piston block 83 and the inside of the deflation cylinder 81 increases, the gas inside the telescopic airbag 7 can be depressurized, so as to reduce the clamping force between the telescopic airbag 7 and the sound, thereby facilitating the removal of the sound.

[0035] Then the threaded rod 82 is reset to reset the piston block 83 to the innermost part of the deflation cylinder 81, so that the gas is re-input into the telescopic airbag 7 for reuse in the later stage.

[0037] In the utility model, the damper 12 is used to reduce the shock between the box body 1 and the moving plate 13, and then the universal wheel at the bottom of the moving plate 13 is used to move the device as a whole.

[0038] Reference Figure 4 A limiting groove 21 is provided on the top of the support plate 2, and the limiting groove 21 is used to limit the two sides of the telescopic airbag 7.

[0039] In the utility model, the limiting groove 21 is provided to enable the telescopic airbag 7 to be guided and limited, so as to ensure that the telescopic airbag 7 can be clamped and fixed along the support plate 2 .
