Description

Technical Field

[0001] The utility model relates to the technical field of sound racks, in particular to a mobile sound rack for performances. Background Art

[0002] Speakers are a type of equipment used to increase the volume, and are generally used to amplify the sound during performances or speeches. Speaker stands are specially used to place audio equipment, and are divided into multiple partitions, on which audio equipment of various shapes can be placed.

[0003] At present, most of the existing sound racks are tripod structures. When outdoor performances encounter strong winds, the wind force generated by the strong winds causes the sound rack to shake, affecting the sound playback effect. Therefore, the sound rack needs to be reinforced. However, the tripod reinforcement requires manual transportation of the counterweight device and placing the configuration device at the bottom of the tripod, so that the overall center of gravity of the bottom of the tripod moves downward to make the device more stable. Since the configuration device needs to be manually transported from the placement position to the side of the sound rack and reinforced, the transportation process increases the workload of the staff, making the reinforcement process time-consuming and labor-intensive, and lacks automation.

[0025] Example

[0026] Reference Figure 1-Figure 3 , which is an embodiment of the utility model, provides a mobile sound stand for performances, including: a sound stand unit 100 and a reinforcement unit 200.

[0027] The sound rack unit 100 includes a base 101 and four sets of universal wheels 102 fixedly installed at the bottom corners of the base 101. A support frame 103 is fixedly installed on the axis of the top of the base 101. A support plate 104 is fixedly installed at one end of the support frame 103 away from the base 101. The sound rack unit 100 also includes a clamping assembly 105 for fixing the sound.

[0028] Furthermore, the reinforcement unit 200 includes a motor 201 fixedly mounted on the bottom axis of the support plate 104 and a rotating shaft 202 fixedly mounted on the output shaft of the motor 201, the rotating shaft 202 is fixedly connected to a driving gear 203 at one end away from the motor 201, and the front and rear ends of the driving gear 203 are meshed with two groups of driven gears 204 rotatably connected to the top of the inner wall of the base 101, and the ends of the two groups of driven gears 204 away from the driving gear 203 are meshed with two groups of racks 205 slidably connected to the front and rear ends of the inner wall of the base 101, and one end of the two groups of racks 205 is fixedly connected to a counterweight 206, the motor 201 drives the rotating shaft 202 to rotate, the rotation of the rotating shaft 202 drives the driving gear 203 to rotate, the rotation of the driving gear 203 drives the two groups of driven gears 204 to rotate, the rotation of the two groups of driven gears 204 drives the two groups of racks 205 to move, and the movement of the two groups of racks 205 drives the counterweight 206 to expand to both sides.

[0029] The bottom of the counterweight 206 is on the same horizontal line as the bottom of the universal wheel 102, the cross section of the counterweight 206 is in a right angle shape, the material of the counterweight 206 is a lead block, the bottom of the counterweight 206 is coated with a smooth coating, which can reduce the friction between the counterweight 206 and the ground when it moves, one end of the motor 201 is located at the axis of the top of the support frame 103, the support columns of the support frame 103 are distributed in a triangular shape, the inner side of the splint 1054 and the top of the support plate 104 are provided with rubber pads, the cross section of the splint 1054 is U-shaped, and multiple groups of heat dissipation holes are opened on both sides of the splint 1054, and the heat dissipation holes are distributed in an array. When the sound system causes heat to accumulate on the side wall and the splint of the sound system due to long-term operation When heat accumulates between the side walls 1054, the accumulated heat here can be discharged outwardly through multiple heat dissipation holes, which effectively solves the defect that the internal electrical components of the audio system work in an overheated environment for a long time due to heat accumulation, resulting in a shortened service life of the system. The counterweight block 206 is deployed to both sides to reinforce the device as a whole. The counterweight block 206 is deployed to both sides to make the center of gravity distribution more uniform, thereby making the bottom of the audio stand more stable, thereby achieving overall reinforcement of the bottom of the audio stand to avoid the situation where the wind blows the audio system to the left and right and causes poor playback effect. At the same time, the main body can be automatically reinforced, and there is no need to manually carry the counterweight device for reinforcement, making the reinforcement process more time-saving and labor-saving.

[0030] The clamping assembly 105 includes a slide groove 1051 opened in the middle position of the top of the support plate 104 and a double-headed screw 1052 rotatably connected to the two ends of the inner wall of the slide groove 1051, both sides of the outer wall of the double-headed screw 1052 are threadedly connected with sliders 1053 that are slidably connected to the inner wall of the slide groove 1051, and the tops of the two groups of sliders 1053 are fixedly installed with clamping plates 1054, and one end of the double-headed screw 1052 is fixedly connected with a knob 1055 that passes through one side of the support plate 104. The clamping assembly 105 can clamp the speaker through the clamping plate 1054 to prevent the speaker from shaking due to accidental contact during the performance. At the same time, it can clamp and tighten the speaker stand when it is transported and moved to prevent it from falling due to shaking left and right.

[0031] During use, when there is a strong wind during the performance, the driving motor 201 is operated, the motor 201 drives the rotating shaft 202 to rotate, the rotating shaft 202 drives the driving gear 203 to rotate, the driving gear 203 drives the two sets of driven gears 204 to rotate, the two sets of driven gears 204 drive the two sets of racks 205 to move in opposite directions, and then the two sets of racks 205 move to drive the counterweights 206 to expand to both sides, the counterweights 206 expand to both sides so that the center of gravity of the device is more evenly distributed, so that the bottom of the sound stand is more stable, thereby realizing the overall reinforcement of the bottom of the sound stand to avoid the occurrence of The wind blows the speakers to shake left and right, resulting in poor playback effects. At the same time, the main body can be automatically reinforced, and there is no need to manually carry the counterweight device for reinforcement, making the reinforcement process more time-saving and labor-saving. The clamping assembly 105 drives the two sets of clamping plates 1054 to move relative to each other through the rotation of the knob 1055, and the clamping plate 1054 can clamp the speakers to avoid accidentally touching the speakers during the performance and causing them to shake. At the same time, the speaker rack can be clamped and tightened when it is transported and moved to prevent it from falling due to shaking left and right.
