Description

Technical Field

[0001] This utility model relates to the field of sound support equipment technology, and in particular to a stage sound support device that is easy to adjust. Background Technology

[0002] Stage sound, like an invisible musician, weaves a symphony of sound waves within the theater space. With a meticulously designed acoustic framework, it precisely transmits the delicate vibrato of vocals, the powerful resonance of instruments, and the immersive atmosphere of environmental sound effects through a multi-dimensional layout of the main sound reinforcement system, monitors, and surround sound. The sound engineer, like a magician of sound, manipulates equalization, compression, and reverberation parameters at the mixing console, balancing the sound field layers and ensuring each note finds its optimal resonant frequency. This allows front-row audience members to perceive the subtle details of the actors' breathing, while those in the back can feel the vibrations in their chests. The integration of modern digital mixing consoles and network audio protocols further enhances the technological appeal of real-time tracking of moving sound sources and intelligent sound field modeling. When spotlights pierce the darkness, the sound system transforms into an emotional conduit connecting actors and audience, converting the emotional tension of the story and the soulful rhythm of the music into tangible sound wave energy, resonating powerfully under the theater's dome.

[0003] Currently, common stage sound support devices are either fixed, immovable bases lacking flexibility, or tripods with poor stability, making it difficult to support large equipment. Although some devices are equipped with casters and adjustable feet at the bottom for movement and positioning, they are still very inconvenient to use. After moving, the feet at the four corners need to be manually adjusted to level them, which is time-consuming and laborious. When moving again, the feet must be rotated in the opposite direction to raise them above the casters before they can be pushed, making the operation cumbersome. Therefore, in actual use, these existing support devices cannot adequately meet the needs of stage sound equipment for fast, convenient, and stable support. Utility Model Content

[0004] One objective of this invention is to provide a conveniently adjustable stage sound support device. This invention addresses the problems mentioned in the background regarding commonly used stage sound support devices, which are either fixed bases that lack flexibility or tripods with poor stability, making it difficult to support large equipment. Although some devices are equipped with casters and adjustable feet at the bottom for movement and positioning, they are still very inconvenient to use. After movement, the feet at the four corners need to be manually adjusted for leveling, which is time-consuming and laborious. When moving again, the feet must be rotated in the opposite direction to raise them above the casters before they can be pushed, making the operation cumbersome.

[0005] An easily adjustable stage sound support device according to an embodiment of the present invention includes:

[0006] Support components, including support plates;

[0007] A lifting assembly is installed on the top of the support plate in the support assembly and is used to support or adjust the support height of the stage sound system. The lifting assembly includes a positioning sleeve fixed inside the support plate. A lifting column is movably provided on the top of the positioning sleeve, and a sound system mounting base for fixing the stage sound system is fixed on the top of the lifting column.

[0008] A moving mechanism, installed at the bottom of the support plate in the support assembly, is used to facilitate the movement and positioning of the stage sound support device. The moving mechanism includes a rotating shaft rotatably mounted on the bottom of the support plate via a first positioning seat, and a second positioning seat fixed on the bottom of the support plate near the first positioning seat. Both ends of the rotating shaft are fixedly provided with first U-shaped brackets, and gears are fixedly provided on the outer side of the rotating shaft. A second U-shaped bracket is rotatably mounted inside the first U-shaped bracket via a cross rotating seat. A fixed shaft is fixedly provided at the tail end of the second U-shaped bracket. A leg is installed inside the fixed shaft, and a caster wheel is installed at one end of the leg. The leg is connected to the gear via a drive assembly to achieve folding and unfolding movement.

[0009] Preferably, a protective railing is fixedly installed on the top periphery of the support plate, and anti-slip support legs are fixedly installed at the four corners of the bottom of the support plate.

[0010] Preferably, each of the lifting columns has a positioning hole on its outer side, and the positioning sleeve has a first elastic locking pin movably disposed on one side corresponding to the positioning hole. The first elastic locking pin is adapted to the positioning hole and is engaged to achieve locking after height adjustment.

[0011] Preferably, the first positioning seat is fixed to the bottom of the support plate.

[0012] Preferably, the fixed shaft is rotatably positioned inside the second positioning seat.

[0013] Preferably, the legs are fixed to a fixed shaft by bolts.

[0014] Preferably, the drive assembly includes a gear plate on the top of the meshing transmission gear and a drag groove opened on the upper outer side of the lifting column. The gear plate slides horizontally inside the first positioning seat. A push-pull rod is rotatably provided on the top of the gear plate. A third U-shaped bracket is rotatably provided on the top of the push-pull rod on both the left and right sides. A docking groove is opened inside the third U-shaped bracket on the left side. A docking block is fixedly provided at one end of the third U-shaped bracket on the right side corresponding to the docking groove. The third U-shaped bracket is sleeved on the outside of the drag groove.

[0015] Preferably, the docking block and the docking groove are adapted to each other and are snap-fitted together. The third U-shaped bracket on the left side is movably provided with a second elastic locking pin at one end corresponding to the docking block, which is used to lock the connection between the two third U-shaped brackets.

[0016] The beneficial effects of this utility model are:

[0017] This invention effectively avoids the problems of cumbersome, time-consuming, and labor-intensive operation during movement and adjustment of existing devices by setting up lifting components, moving mechanisms, and driving components. When it is necessary to adjust the height of the speaker, the lifting column is manually lifted to drive the drag groove to rise synchronously. At this time, the push-pull rod is subjected to the upward force by the sleeve action of the third U-shaped card seat and the drag groove, driving the toothed plate to slide horizontally along the first positioning seat. Then, through gear meshing transmission, the rotating shaft is driven to rotate, causing the feet on the fixed shaft to retract inward around the cross rotating seat. At this time, the casters will be stored at the bottom of the support plate, and the anti-slip legs at the bottom of the support plate will provide stable support. Conversely, when the lifting column is lowered, the push-pull rod pushes the toothed plate in the opposite direction, and the gear reverses to drive the feet to unfold outward. At this time, the casters contact the ground to achieve the moving state, avoiding the cumbersome operation of manually adjusting the four corner feet for leveling after movement. When moving again, there is no need to rotate the feet in the opposite direction, making the operation simple and quick.

[0018] This invention effectively avoids the problems of poor stability and inability to support large equipment in existing tripods by setting up support components. When the tripod is stored, the anti-slip legs make direct contact with the ground at multiple points to form a stable support surface to distribute the load of large speakers. The guardrail surrounds the speaker mounting base to form a limiting zone. When the equipment is impacted by external forces, the welded structure between the guardrail and the support plate prevents the speaker from sliding sideways, ensuring that the stage sound equipment is reliably supported in all directions. This avoids safety hazards caused by insufficient stability and ensures the safe use of stage sound equipment. Attached Figure Description

[0025] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0026] refer to Figure 1-4 A stage sound support device that is easy to adjust, comprising:

[0027] Support component 1 includes support plate 101;

[0028] The lifting assembly 2 is installed on the top of the support plate 101 in the support assembly 1 and is used to support or adjust the support height of the stage sound system. The lifting assembly 2 includes a positioning sleeve 201 fixed inside the support plate 101. A lifting column 202 is movably installed on the top of the positioning sleeve 201. A sound mounting base 205 for fixing the stage sound system is fixed on the top of the lifting column 202. By operating the lifting column 202 to move up and down in the positioning sleeve 201, the height of the stage sound system can be easily adjusted to adapt to different stage layouts and sound requirements, achieving a fast, convenient and stable support effect.

[0029] The moving mechanism 3, installed at the bottom of the support plate 101 in the support assembly 1, is used to facilitate the movement and positioning of the stage sound support device. The moving mechanism 3 includes a rotating shaft 303 rotatably mounted on the bottom of the support plate 101 via a first positioning seat 301, and a second positioning seat 302 fixed to the bottom of the support plate 101 near the first positioning seat 301. Both ends of the rotating shaft 303 are fixedly provided with first U-shaped retaining seats 304, and gears 305 are fixedly provided on the outer side of the rotating shaft 303. Inside the card holder 304, a second U-shaped card holder 307 is rotatably mounted via a cross-shaped rotating seat 306. A fixed shaft 308 is fixedly mounted at the tail end of the second U-shaped card holder 307. A foot 309 is installed inside the fixed shaft 308. A caster wheel 311 is mounted at one end of the foot 309. The foot 309 is connected to a gear 305 via a drive assembly 4 to achieve folding and unfolding movement. The drive assembly 4 includes a gear plate 401 meshing with the gear 305 and a drag groove 206 located on the upper outer side of the lifting column 202. 01 is located inside the first positioning seat 301 and slides horizontally. A push-pull rod 403 is rotatably mounted on the top of the toothed plate 401. A third U-shaped bracket 404 is rotatably mounted on the top of the push-pull rod 403 on both the left and right sides. The third U-shaped bracket 404 on the left side has a docking groove 406 inside. A docking block 405 is fixedly mounted on one end of the third U-shaped bracket 404 on the right side corresponding to the docking groove 406. The third U-shaped bracket 404 is sleeved on the outside of the drag groove 206. When it is necessary to adjust the height of the speaker, the lifting column is manually pulled. The moving drag groove rises synchronously. At this time, the push-pull rod is subjected to upward force by the sleeve action of the third U-shaped bracket and the drag groove, driving the toothed plate to slide horizontally along the first positioning seat. Then, through gear meshing transmission, it drives the rotating shaft to rotate, causing the legs on the fixed shaft to retract inward around the cross rotating seat. At this time, the casters will be stored at the bottom of the support plate, and the anti-slip legs at the bottom of the support plate will provide stable support. Conversely, when the lifting column is lowered, the push-pull rod pushes the toothed plate in the opposite direction, and the gear reverses to drive the legs to unfold outward. At this time, the casters contact the ground to achieve the moving state.

[0030] Example 1: A guardrail 102 is fixedly installed on the top periphery of the support plate 101. The welded structure between the guardrail and the support plate prevents the speaker from sliding sideways. Anti-slip legs 103 are fixedly installed at the four corners of the bottom of the support plate 101. The anti-slip legs directly contact the ground at multiple points to form a stable support surface to distribute the load of the large speaker. Positioning holes 203 are opened on the outer side of the lifting column 202. A first elastic locking pin 204 is movably installed on one side of the positioning sleeve 201 corresponding to the positioning hole 203. The first elastic locking pin 204 is adapted to the positioning hole 203 and is locked in place to achieve locking after height adjustment. The first positioning seat 301 is fixed to the bottom of the support plate 101. The fixed shaft 308 is rotatably installed inside the second positioning seat 302. The leg 309 is fixed to the fixed shaft 308 by bolts 310, which can facilitate the disassembly and replacement of the leg.

[0031] Example 2: The mating block 405 and the mating groove 406 are adapted to each other and are designed to engage, ensuring that they can be precisely mated and firmly connected. The third U-shaped bracket 404 on the left side is movably provided with a second elastic locking pin 407 at one end corresponding to the mating block 405, which is used to lock the connection between the two third U-shaped brackets 404. The elastic locking pin 407 can automatically pop out and engage with the corresponding structure on the mating block 405 after the mating block 405 is inserted into the mating groove 406 and reaches the preset position, thereby locking the connection between the two third U-shaped brackets 404 and preventing them from accidentally loosening.

[0032] Working principle: First, when the height of the speaker needs to be adjusted, the lifting column 202 is manually pulled up or down to move up and down within the positioning sleeve 201. The drag groove 206 moves synchronously with the lifting column 202, driving the third U-shaped bracket 404 sleeved on its outer side to move in conjunction. Subsequently, the third U-shaped bracket 404 pushes or pulls the toothed plate 401 horizontally along the first positioning seat 301 via the push-pull rod 403. The toothed plate 401 meshes with the gear 305, driving the rotating shaft 303 to rotate, causing the first U-shaped brackets 304 at both ends to rotate around the axis. The first U-shaped brackets 304 are linked to the second U-shaped bracket 307 via the cross rotating seat 306, driving the stand 309 on the fixed shaft 308 to rotate around the second positioning seat 302 to unfold or retract. When the lifting column 202 rises, the push-pull rod 403 applies force to move the toothed plate 401 to the left, and the gear 305 drives the rotating shaft 303 to rotate counterclockwise. The stand 309 rotates around the cross rotating seat 306 to unfold or retract. The device folds inwards for storage, with the casters 311 off the ground. The anti-slip legs 103 at the four corners of the bottom of the support plate 101 contact the ground to provide stable support. Conversely, when the lifting column 202 descends, the push-pull rod 403 pushes the toothed plate 401 to the right, the gear 305 drives the rotating shaft 303 to rotate clockwise, the stand 309 unfolds outwards, and the casters 311 contact the ground to achieve movement. During this process, after the docking block 405 is inserted into the docking slot 406, the second elastic locking pin 407 automatically pops out and engages, locking the connection of the left and right third U-shaped brackets 404. After the height of the lifting column 202 is adjusted, the first elastic locking pin 204 engages with the corresponding positioning hole 203 to achieve mechanical locking. At the same time, the protective railing 102 on the top of the support plate 101 surrounds the speaker mounting base 205 to form a protective zone. Combined with the multi-point support structure of the anti-slip legs 103, the speaker load is distributed and the equipment is prevented from sliding sideways. Therefore, the device is easy to operate and highly stable.

Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
