Furthermore, a screw and a rotating block are coupled together, and the corresponding mounting plate can be adjusted by controlling the connecting block of the trigger assembly. When the connecting block is controlled to move downward, the locking slot engages with the annular groove, and the connecting block moves to a second position. The connecting block restricts the rotation of the rotating block, allowing the screw to rotate and drive the rotating block in the first direction, adjusting the position of the corresponding mounting plate. However, other connecting blocks that are not coupled to the rotating block are unable to drive the rotating block, leaving the mounting plate fixed. This achieves the effect of adjusting individual mounting plates. While using a single screw drive, the trigger assembly allows the position of each mounting plate to be adjusted independently, enhancing the flexibility of adjusting the spacing of the suspended sound-absorbing panels.

[0031] The embodiments of the present invention are intended to introduce and illustrate the structural components of a spacing adjustment device for suspended sound-absorbing panels and the coordination between the various components. Unless otherwise specified, the dimensions, materials, and manufacturing processes of the various components of the spacing adjustment device for suspended sound-absorbing panels in the embodiments of the present invention can be selected according to specific circumstances and are not specifically limited or described herein.

[0032] Furthermore, in order to provide the public with a better understanding of the present invention, some specific details are described in detail in the following detailed description of the present invention, but those skilled in the art can fully understand the present invention without the description of these details.

[0033] Example 1 Reference Figure 1The present invention provides a spacing adjustment device for suspended sound-absorbing panels, which is mounted and fixed above an indoor space. The device comprises a frame 1, a mounting plate 2, an adjustment assembly 3, and a trigger assembly 4. The frame 1 is fixed to the roof. Multiple mounting plates 2 are provided, arranged in a first direction a. Suspension points (not shown) are provided below the mounting plates 2 for attaching the suspended sound-absorbing panels. Multiple adjustment assemblies 3 are provided, each of which can be connected to the mounting plates 2 to adjust the spacing between the individual mounting plates 2. The trigger assembly 4 is used to control the operation of the adjustment assemblies 3.

[0034] Reference Figure 2-4 The plurality of mounting plates 2 are all slidably connected to the frame 1 along a first direction a. A screw 5 is disposed within the frame 1, and the axis of the screw 5 is aligned with the first direction a. The adjustment assembly 3 can be moved by interacting with the screw 5. The adjustment assembly 3 includes a rotating block 31 and a connecting member 32. The rotating block 31 has a threaded hole disposed therein, into which the screw 5 is threadedly connected. The rotating block 31 and the mounting plates 2 are connected via the connecting member 32. An annular groove 311 is defined in the middle of the rotating block 31. The annular groove 311 has a rectangular cross-section and can cooperate with the trigger assembly 4 to control the movement of the adjustment assembly 3.

[0035] The trigger assembly 4 includes a connecting block 41, which can slide along the first direction a within the frame 1 and can move up and down. A slot 411 is provided below the connecting block 41. When the connecting block 41 moves downward, the slot 411 can be engaged with the annular groove 311, limiting the rotating block 31 from rotating synchronously with the screw 5. The positional relationship between the connecting block 41 and the rotating block 31 includes a first state and a second state. The first state is when the connecting block 41 is above the rotating block 31, the slot 411 is disengaged from the annular groove 311, and the rotating block 31 can rotate with the screw 5; the second state is when the slot 411 is engaged with the annular groove 311. It should be noted that a reduction motor (not shown in the figure) that drives the screw 5 can be fixed to the outside of the frame 1. The reduction motor driving the screw 5 to rotate is a prior art and will not be described in detail in this application.

[0036] In the prior art, suspended sound-absorbing panels are typically suspended by directly fixing the suspension ropes to the ceiling or decorative panels, making it difficult to adjust the spacing between multiple groups of sound-absorbing panels. In this application, a frame 1 and a mounting plate 2 are provided, and the sound-absorbing panels are suspended on the mounting plate 2. As the mounting plate 2 moves, the spacing between adjacent sound-absorbing panels can be adjusted by repositioning the suspension points without resetting the suspension points, making adjustment easy.

[0037] Furthermore, the screw rod 5 and the rotating block 31 cooperate to control the connecting block 41 of the trigger assembly 4, thereby adjusting the movement of the corresponding mounting plate 2. When the connecting block 41 is controlled to move downward, the engaging groove 411 engages with the annular groove 311, and the connecting block 41 moves to the second state. The connecting block 41 restricts the rotation of the rotating block 31, allowing the screw rod 5 to rotate and drive the rotating block 31 in the first direction, adjusting the position of the corresponding mounting plate 2. Since the other connecting blocks 41 do not cooperate with the rotating block 31, the screw rod 5 cannot drive the rotating block 31, and the position of the mounting plate 2 remains unchanged. This achieves the effect of adjusting a single mounting plate 2. While using a single screw rod 5 as a driving force, the trigger assembly 4 allows the position of each mounting plate 2 to be adjusted individually, thereby enhancing the flexibility of adjusting the spacing between the suspended sound-absorbing panels.

[0038] Reference Figure 4 As an embodiment, the trigger assembly 4 further includes a trigger block 42 and a drive cylinder 43. The cylinder body of the drive cylinder 43 is slidably connected to the frame 1 along the first direction a. The length direction of the drive cylinder 43 is the second direction b, which is perpendicular to the first direction a. The trigger block 42 is fixed to the telescopic rod of the drive cylinder 43. When the drive cylinder 43 is in operation, it can push the trigger block 42 to move along the second direction b.

[0039] An inclined surface 412 is provided on the upper side of the connecting block 41, and the inclined surface 412 is inclined downwardly away from the side of the mounting plate 2. When the trigger block 42 moves laterally along the second direction b, it can abut against the inclined surface 412, pushing the connecting block 41 to move downward, thereby enabling the slot 411 to be locked into the annular groove 311, preventing the rotating block 31 from rotating, so that the screw 5 can drive the rotating block 31 and the mounting plate 2 to move laterally along the first direction.

[0040] Furthermore, the trigger block 42 includes a first vertical rod 421, a second vertical rod 422, and a cross rod 423. The cross rod 423 is fixed between the first vertical rod 421 and the second vertical rod 422, and is located at the upper ends of the first vertical rod 421 and the second vertical rod 422. The first vertical rod 421, the second vertical rod 422, and the cross rod 423 surround and form a receiving groove 424. The first vertical rod 421 is fixed to the end of the telescopic rod of the drive cylinder 43, so that the drive cylinder 43 can push the entire trigger block 42 to move, so that the second vertical rod 422 can act on the inclined surface 412 to push the connecting block 41 from the first state to the second state. In the first state, the connecting block 41 can be located in the receiving groove 424. In the second state, the upper end of the connecting block 41 can abut the lower end of the second rod body.

[0041] A vertically arranged vertical rod 6 is connected in the frame 1 so as to slide along the first direction a. A connecting piece 413 is fixed to one side of the connecting block 41. The vertical rod 6 is passed through the connecting piece 413. The connecting piece 413 can slide on the vertical rod 6 in the vertical direction. A first spring 61 is fixed between the frame 1 and the connecting piece 413. The first spring 61 is sleeved on the outside of the vertical rod 6. Under normal circumstances, the first spring 61 drives the connecting piece 413 to move upward, so that the connecting block 41 is restored from the second state to the first state.

[0042] When the telescopic rod of the driving cylinder 43 is not extended, the first spring 61 is in normal state, and the connecting block 41 is located in the accommodating groove 424. When the telescopic rod of the driving cylinder 43 is extended, the second rod body moves horizontally along the second direction b, and the second rod body pushes the inclined surface 412 horizontally, forcing the connecting block 41 to move downward until the slot 411 is engaged with the annular groove 311, so that the connecting block 41 is in the second state. The lower end of the second rod body presses against the connecting block 41 to maintain the position of the connecting block 41, thereby maintaining the cooperation between the slot 411 and the annular groove 311. At this time, the rotating block 31 is prevented from rotating, so that the screw 5 can drive the rotating block 31 to move horizontally. In the second state, the first spring 61 is in a stretched state. When the telescopic rod of the driving cylinder 43 is retracted, it is free from the restriction of the trigger block 42. Under the action of the first spring 61, the connecting block 41 will be recovered to the first state. As the trigger block 42 is recovered, it gradually moves into the accommodating groove 424 and returns to the first state, so as to be ready for the next cooperation with the trigger block 42 to complete the state transformation and control the adjustment component 3 to adjust the spacing between the mounting plates 2.

[0043] As an embodiment, an insert block 4211 is fixed to one side of the first vertical rod 421, and a slot 21 is opened at the end of the mounting plate 2. The insert block 4211 can be inserted into the slot 21. When the telescopic rod of the driving cylinder 43 is extended, as the second vertical rod 422 pushes the connecting block 41 to move to the second state, the insert block 4211 is also inserted into the slot 21, combining the trigger assembly 4, the adjustment assembly 3 and the mounting plate 2 together, so that when the screw 5 rotates, it can drive the adjustment assembly 3, the trigger assembly 4 and the mounting plate 2 to move synchronously and stably along the first direction a.

[0044] Furthermore, a notch groove 4212 is provided on the side of the first vertical rod 421 away from the insertion block 4211. The height of the notch groove 4212 is the same as the height of the rotating block 31. When the telescopic rod of the driving cylinder 43 is not extended, the first vertical rod 421 is set close to the rotating block 31. The notch groove 4212 can avoid the rotating block 31, thereby preventing the first vertical rod 421 from affecting the rotating block 31 from rotating freely with the screw 5.

[0045] Reference Figure 2 As an embodiment, a ring 312 is fixed at both ends of the rotating block 31 , and the ring 312 and the screw 5 are coaxially arranged. The ring 312 can rotate with the rotation of the rotating block 31 .

[0046] Two connecting members 32 are provided for each mounting plate 2. These connecting members 32 are located between the mounting plate 2 and the adjustment assembly 3, with the connecting rod located at the end of the rotating block 31. The connecting member 32 includes a curved plate 321 and a bent connecting rod 322. The curved plate 321 is a semicircular plate coaxially arranged with the screw 5. The ring 312 is rotatably connected to the curved plate 321, meaning that the ring 312 can only rotate within the curved plate 321. The bent connecting rod 322 is an "L"-shaped rod. The curved plate 321 is fixed to the upper end of the bent connecting rod 322, and the end of the bent connecting rod away from the curved plate 321 is fixed to the side of the mounting plate 2.

[0047] When the screw 5 is in the first state, the rotation of the screw 5 will drive the rotating block 31 and the ring 312 to rotate synchronously. At this time, the rotating block 31 does not move in the first direction a, so that the mounting plate 2 is not driven by the rotation of the screw 5; when it is necessary to adjust the spacing between a single group of hoisted sound-absorbing panels and other groups of attraction panels, the corresponding driving cylinder 43 can be operated, and the telescopic rod of the driving cylinder 43 is extended to push the connecting block 41 to the second state. By relying on the engagement of the card slot 411 and the annular groove 311, the rotation of the rotating block 31 is limited. As the screw 5 rotates, relying on the threaded connection between the screw 5 and the internal threaded hole of the rotating block 31, the rotating block 31 will move in the first direction a. At this time, it can drive the ring 312 to move, and then drive the connecting piece 32 to move, thereby driving the single mounting plate 2 to move, realizing the flexible movement of a single group of hoisted mounting plates 2, so that the spacing between each group of mounting plates 2 can be flexibly adjusted.

[0048] As an embodiment, the frame 1 includes two end plates 11 and a side plate 12, the two end plates 11 are fixedly connected to the two opposite ends of the side plates 12, the end plates 11 and the side plates 12 are vertically arranged, and the two end plates 11 and the side plates 12 enclose a mounting groove, and each mounting plate 2 is slidably connected in the mounting groove along the first direction a.

[0049] Reference Figure 2 and Figure 4 The screw rod 5 is rotatably connected between the two end plates 11. A first assembly rod 13 and a second assembly rod 14 are also fixed between the two end plates 11. The first assembly rod 13 is located above the second assembly rod 14. A slide rail 141 is fixed to the upper side of the second assembly rod 14. A slider 142 is slidably connected to the upper side of the slide rail 141 along the first direction a. The drive cylinder 43 is fixed above the slider 142. A slide groove 131 is formed on the lower side of the first assembly rod 13. The slide groove 131 extends in the first direction a. A moving block 132 is slidably connected to the slide groove 131 along the first direction a. The vertical rod 6 is fixed to the lower side of the moving block 132. The first assembly rod 13 and the second assembly rod 14 can respectively stably mount the vertical rod 6 and the drive rod, allowing the trigger assembly 4 to stably slide within the frame 1.

[0050] Reference Figure 3 Furthermore, two stabilizing rods 15 are fixed between the first end plate 11 and the second end plate 11. The extension direction of the two stabilizing rods 15 is the first direction a, and the arrangement direction of the two stabilizing rods 15 is the second direction b. Two connecting blocks 22 are fixed on the upper side of each mounting plate 2. The connecting blocks 22 are slidably connected to the bottom of the stabilizing rod 15 along the first direction a, thereby improving the stability of the moving rod of the mounting plate 2.

[0051] Reference Figure 5 Furthermore, a first guide groove 121 and a second guide groove 122 are opened on the side panel 12. The first guide groove 121 and the second guide groove 122 are connected to each other. The height of the first guide groove 121 is less than the height of the second guide groove 122. The first guide groove 121 is located on the surface of the side panel 12, and the second guide groove 122 is located inside the side panel 12.

[0052] Reference Figure 3 and Figure 5 , a through slot 23 is provided in the mounting plate 2, and the extension direction of the through slot 23 is the second direction b. One end of the through slot 23 extends to the side of the mounting plate 2 close to the side plate 12, and the other end of the through slot 23 is connected to the slot 21. A long rod 231 is inserted in the through slot 23, and the side periphery of the long rod 231 abuts against the through slot 23. A stabilizing block 232 is fixed to the end of the long rod 231 close to the side plate 12. The thickness of the stabilizing block 232 is greater than the thickness of the long rod 231, and the thickness of the stabilizing block 232 is the same as the height of the first guide slot 121. When the trigger assembly 4 moves, when the insert block 4211 is inserted into the slot 21, the insert block 4211 can support the long rod 231, so that the long rod 231 can slide in the through slot 23, thereby driving the stabilizing block 232 to move from the first guide slot 121 to the second guide slot 122. When the stabilizing block 232 is located in the first guide groove 121 , the upper and lower sides of the first guide groove 121 respectively abut against the stabilizing block 232 , thereby limiting the position of the stabilizing block 232 through friction, avoiding free sliding of the stabilizing block 232 , and maintaining the stability of the mounting plate 2 .

[0053] Reference Figure 4 An inner groove 24 is provided on the upper side of the through groove 23, and a plurality of second springs 241 are fixed in the inner groove 24. A push block 243 is fixed to the end of the second spring 241, and the push block 243 is fixed to the end of the long rod 231. Under normal circumstances, the second spring 241 can push the long rod 231 and the push block 243 to move into the slot 21, and in this state, the stabilizing block 232 is located in the first guide groove 121.

[0054] When it is necessary to adjust the position of a single mounting plate 2, the telescopic rod corresponding to the driving cylinder 43 pushes the trigger block 42 to move, and the trigger block 42 can push the connecting block 41 to move to the second state, so that the adjustment component 3 and the screw 5 can cooperate to move the position of the mounting plate 2. At this time, the plug block 4211 is inserted into the slot 21, and the plug block 4211 can push the long rod 231 and the push block 243, compress the second spring 241, and push the stabilizing block 232 into the second guide groove 122. The upper and lower sides of the second guide groove 122 do not contact the stabilizing block 232. At this time, the stabilizing block 232 has no restriction, so that the entire adjustment component 3 can drive the mounting plate 2 to move smoothly.

[0055] During the above process, the other mounting plates 2 adjacent to the above mounting plate 2 are not in a state of being adjusted. As the screw 5 rotates, the rotating block 31 is driven to rotate, which will cause the mounting plate 2 to shake. At this time, the stabilizing block 232 is located in the first guide groove 121, and the upper and lower sides of the stabilizing block 232 are respectively in contact with the guide groove. Relying on the friction between the stability and the side wall of the first guide groove 121, the impact on the non-moving mounting plate 2 can be reduced, and the position of the mounting plate 2 can be stabilized.

[0056] It should be noted that the upper and lower surfaces of the first guide groove 121 may be coated with damping oil to adjust the friction between the first guide groove 121 and the stabilizing block 232 .

[0057] Furthermore, multiple guide wheels 1221 are rotatably connected on both the upper and lower sides of the second guide groove 122, and the multiple guide wheels 1221 are arranged along the first direction a, and the axial direction of the guide wheel 1221 is the second direction b. The upper and lower sides of the stabilizing block 232 can abut against the guide wheels 1221.
