Description

Technical Field

[0001] The invention relates to a decorative panel assembly technology, in particular to an assembled indoor sound-absorbing decorative panel. Background Art

[0002] Compared with traditional decoration methods, prefabricated sound-absorbing panels can be quickly assembled through simple modular connection methods during installation, which greatly improves installation efficiency and reduces the difficulty of manual operation and the risk of construction errors. Prefabricated panels are usually equipped with convenient connection designs such as quick locks or card slots, reducing dependence on professional technology;

[0003] A Chinese invention patent with publication number CN111997293A discloses an assembled decorative panel structure for interior decoration. By means of the provided locking parts and assembly parts, when two decorative panels are spliced, the adjacent trigger rods and receiving blocks interact with each other to achieve self-locking, so that the position of the decorative panel is automatically fixed, which can not only ensure the stability of the decorative panel installation, but also avoid the operation of fixing by screw drilling, and the installation is more convenient and reliable. However, when assembling in this way, it is necessary for the adjacent decorative panels to have a certain reserved gap so that the adjacent trigger rods and receiving blocks can interact with each other. When the decorative panels are assembled on a wall, they are compact. When assembling to the last few decorative panels, they are restricted by the other wall on one side of the wall, especially when assembling the last decorative panel, there is often not enough spacing for assembly, resulting in greater assembly difficulty. If it is still necessary to obtain sufficient spacing, the width of the board can only be reduced, resulting in too large a gap between the decorative panel and the adjacent wall after assembly, affecting the connection of the decorative panels between the adjacent walls, thereby affecting the quality of the decorative panel assembly.

[0004] For example, a Chinese utility model patent with publication number CN213359171U discloses an energy-saving decorative panel for building exterior walls. By providing a reversible connecting strip, the user's operating space when installing adjacent base panels is increased, the installation difficulty is reduced, and it is more convenient. However, when one of the base panels is damaged and needs to be replaced, it is necessary to disassemble the base panels (the entire row or column) over a large area. The disassembly and reassembly process is cumbersome and costly, and it is also easy to affect the stability of other panels. Summary of the invention

DETAILED DESCRIPTION

[0035] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0036] For examples, see Figure 1 - Fig.11 , an assembled indoor sound-absorbing decorative panel, comprising an assembly component 3 mounted on the back of a decorative panel 1, and a groove plate 2 fixed to a wall;

[0037] Assembly 3 includes:

[0038] The front end member 31 includes a first rotating shaft 311 , and the first rotating shaft 311 is mounted on one side of the decorative panel 1 through a first bracket 312 ;

[0039] The rear end member 32 includes a limit block 321, one side of the limit block 321 is provided with a limit groove 322 adapted to the first rotating shaft 311, the decorative panel 1 can rotate around the axis of the first rotating shaft 311 in the limit groove 322 of the adjacent decorative panel 1, one end of the limit block 321 is connected to a connecting rod assembly, the connecting rod assembly includes a first connecting rod 323 and a second connecting rod 324 that are rotatably connected to each other, and one end of the second connecting rod 324 is rotatably connected to one side of the decorative panel 1;

[0040] A locking mechanism 4, which is disposed at the rear end member 32 and installed between the groove plate 2 and the decorative panel 1, and has a locking state for restricting the rotation of the decorative panel 1 and an unlocking state for releasing the restriction thereon;

[0041] During assembly, the decorative panel 1 is butted against the front end member 31 and the rear end member 32 of the adjacent decorative panel 1 in an inclined posture in the groove plate 2, and the locking mechanism 4 is in a locked state.

[0042] The sound-absorbing decorative panel 1 needs to be regularly maintained and replaced due to its material properties, performance degradation after long-term use, appearance aging and environmental impacts to ensure its good sound absorption effect, maintain its appearance and meet functional requirements. Through the above-mentioned assembly component 3 setting, when disassembling, the locking mechanism 4 is switched to the unlocked state, and the decorative panel 1 is rotated so that it rotates around the axis of the first rotating shaft 311 in the limiting groove 322 of the adjacent decorative panel 1, so as to disconnect the front end member 31 and the rear end member 32 of the decorative panel 1 from the two adjacent decorative panels 1.

[0043] like Figure 1-3 As shown, in the specific assembly process, the front end component 31 of the decorative panel 1 to be installed is first connected with the rear end component 32 of the previous decorative panel 1, that is, the first rotating shaft 311 on one side of the decorative panel 1 is placed in the limiting groove 322 on the side of the previous decorative panel 1, at this time, the decorative panel 1 is inclined relative to the previous decorative panel 1 or the wall; then the decorative panel 1 is rotated around the first rotating shaft 311, and during the rotation process, the limiting block 321 is placed in the groove plate 2, and as the decorative panel 1 rotates, the limiting block 321 slides in the groove plate 2 under the push of the connecting rod assembly, providing a limiting and guiding effect for the rotation of the decorative panel 1, and when the decorative panel 1 is rotated to be in the same plane as the adjacent decorative panel 1, the locking mechanism 4 switches to the locking state, completing the assembly of the decorative panel 1, at this time, the rear end component 32 on one side of the decorative panel 1 will be used for the docking end when assembling with the next decorative panel 1; it should be noted that, Figure 1 and Figure 2 As shown, a decorative panel 1 with a higher height is usually assembled with the wall through two groove plates 2. Therefore, for the same decorative panel 1, the upper and lower ends thereof are provided with the same assembly components 3 to improve stability. If some of the heights are smaller, only one set is required. Under the premise of stability, the specific arrangement method is determined by the height of the sound-absorbing decorative panel 1 or other factors (weight, etc.);

[0044] It is worth mentioning that, when the staff assembles the decorative panel 1, they only need to observe when the first rotating shaft 311 is docked with the limiting groove 322 and the limiting block 321 is docked with the groove plate 2, and then they only need to push the decorative panel 1 to complete the assembly. Since the decorative panel 1 is assembled in an inclined posture, it provides the staff with a good observation angle and operating space, so as to facilitate the rapid assembly of the decorative panel 1.

[0045] When one of the decorative panels 1 is damaged and needs to be replaced, it is not necessary to destroy the decorative panel 1 or disassemble the decorative panel 1 on a large scale. It is only necessary to switch the locking mechanism 4 on one side of the damaged decorative panel 1 to the unlocked state, and then rotate the decorative panel 1 to make it rotate at a certain angle in an inclined posture. However, at this time, the assembly components 3 of the two adjacent decorative panels 1 will also lose connection with it. When actually disassembling, it can be supported by manual labor or tools.

[0046] In addition, for the first installed decorative panel 1, the front end member 31 thereon also needs to be limited, and a limiting block 321 that cooperates with it can be installed at the end of the groove plate 2. Here, only the limiting block 321 and the groove plate 2 need to be fixed.

[0047] In one embodiment of the present invention, guide rods 325 are provided on both sides of the limit block 321, and the slot plate 2 is provided with access guide grooves 326 for the guide rods 325 to slide. Figure 4 and Figure 5 As shown, when the decorative panel 1 is in an inclined posture, the guide rods 325 on both sides of the limit block 321 are aligned with the entrance of the access guide groove 326 and slid in to complete the preliminary installation. Subsequently, the decorative panel 1 can be directly pushed to make the limit block 321 slide along the access guide groove 326. The setting of the guide rod 325 and the access guide groove 326 makes the movement of the limit block 321 more stable, preventing the limit block 321 from detaching from the slot plate 2.

[0048] In one embodiment of the present invention, a retardation assembly 5 is further provided on the limit block 321, which includes a push rod 51 and a pushing member 52. One end of the push rod 51 is rotatably connected to one end of the first connecting rod 323. A pushing groove 53 for accommodating the pushing member 52 is provided in the limit block 321. The other end of the push rod 51 is slidably connected to the inner wall of the limit block 321 and connected to the pushing member 52. The pushing member 52 is connected to two guide rods 325. The guide rods 325 are slidably connected to the inner wall of the limit block 321. A first spring 54 is sleeved on the surface of the push rod 51. The elastic force of the first spring 54 acts on the push rod 51 to make it have a tendency to move away from the limit block 321. A conical extrusion block 55 is installed on the guide rod 325. The conical extrusion block 55 is squeezed on the edge of the access guide groove 326. When the push rod 51 moves toward the limit block 321, it squeezes the first spring 54 and causes the pushing member 52 to drive the two guide rods 325 to move closer to or away from each other, so that the conical extrusion block 55 is away from the edge of the access guide groove 326.

[0049] like Figure 3 and Figure 6As shown, when the first spring 54 is in an un-pressed state, the pusher 52, under the elastic force of the first spring 54, drives the conical extrusion blocks 55 on the two guide rods 325 to have an extrusion force against the access guide groove 326. Under this extrusion force, the limit block 321 has a certain resistance when moving along the slot plate 2. When the first connecting rod 323 squeezes the push rod 51, the first spring 54 is compressed, and the push rod 51 moves toward the direction close to the limit block 321. The two guide rods 325 are moved by the movement of the pusher 52, thereby reducing the extrusion force between the conical extrusion block 55 and the access guide groove 326. Under a certain thrust of the first connecting rod 323, the limit block 321 will be able to move along the slot plate 2.

[0050] During assembly, after the first rotating shaft 311 of the decorative panel 1 is placed in the limiting groove 322 of the adjacent decorative panel 1, the first rotating shaft 311 will always maintain a certain extrusion force with the limiting groove 322 through the action of the hysteresis component 5, so that one side of the decorative panel 1 has a suitable assembly distance with the edge of the previous decorative panel 1. Specifically, when the decorative panel 1 is assembled in an inclined posture, it rotates around the first rotating shaft 311. During the rotation process, the connecting rod assembly will push the limiting block 321 to slide in the groove plate 2. When the first connecting rod 323 moves, it squeezes the first spring 54. When the first connecting rod 323 provides After the thrust can compress the first spring 54 to a certain extent and move a certain distance, the extrusion pressure between the conical extrusion block 55 and the access guide groove 326 is reduced, so that the limit block 321 can move along the guide groove. In this process, the decorative panel 1 will be subjected to part of the reaction force acting on the first rotating shaft 311 and the limit groove 322, so that the first rotating shaft 311 always maintains a certain extrusion pressure with the limit groove 322 during the rotation of the decorative panel 1, so as to avoid the first rotating shaft 311 from being separated from the limit groove 322 or not being tightly pressed, resulting in excessive gap between the edge of the decorative panel 1 and the previous decorative panel 1.

[0051] Under the above-mentioned setting of the hysteresis assembly 5, when the limit block 321 is placed in the slot plate 2 and connected to the access guide groove 326, the first spring 54 needs to be compressed to a certain extent so that the conical extrusion block 55 is away from the edge of the access guide groove 326, so that the guide rod 325 can enter the access guide groove 326. This process can be manually operated by the staff, and will not be described in detail here;

[0052] In one embodiment of the present invention, a specific example of a push member 52 is provided, the push member 52 includes a trapezoidal push block 521, oblique grooves 522 are provided on both sides of the trapezoidal push block 521, a slide bar 523 is fixedly installed at one end of the guide rod 325, the slide bar 523 is slidably connected with the oblique groove 522, and the conical extrusion block 55 is located outside the slot plate 2;

[0053] In one embodiment of the present invention, another specific example of a push member 52 is provided, the push member 52 includes a spherical push block 524, the end of the guide rod 325 located in the push groove 53 is fixedly connected with a wedge-shaped push plate 525, the wedge-shaped push plate 525 abuts against the surface of the spherical push block 524, and the conical extrusion block 55 is located on the inner side of the groove plate 2;

[0054] Although both of the above two methods can realize the extrusion between the conical extrusion block 55 and the slot plate 2, the method of setting the spherical pushing block 524 tends to make the edge of the slot plate 2 have a tendency to fold outward. For the case where the slot plate 2 has poor structural strength or thin thickness, it is preferred to use the method of setting the trapezoidal pushing block 521 to squeeze the edge of the slot plate 2 inward.

[0055] In one embodiment of the present invention, the locking mechanism 4 includes a trigger member 41 and a locking member 42, wherein the locking member 42 is used to limit the guide rod 325 from moving in the access guide groove 326, the trigger member 41 includes a partition 411 and a slide plate 412, the partition 411 is U-shaped, and a guide column 413 is fixedly connected to the middle thereof, the guide column 413 is slidably connected to the inner wall of the slide plate 412, one end of the slide plate 412 is connected to the pusher 52, the bottom of both ends of the partition 411 has an inclined first inclined surface 414, and a second inclined surface 415 adapted to the first inclined surface 414 is provided in the limit block 321;

[0056] In one embodiment of the present invention, the locking member 42 includes a first socket 421, which is fixedly mounted on the back side of the decorative panel 1, a first plug plate 422 is slidably connected in the first socket 421, a second spring 423 is arranged between the first plug plate 422 and the first socket 421, and the elastic force of the second spring 423 acts on the first plug plate 422 to make it have a tendency to move away from the first socket 421, and a first slot 424 matching with the end of the first plug plate 422 is opened on one side of the partition plate 411;

[0057] When the decorative panel 1 is assembled, the plug plate enters the slot under the action of the second spring 423 to complete the locking. When unlocking is required, the partition plate 411 is pressed to move the partition plate 411 toward the slot plate 2. The partition plate 411 will push the limit block 321 to move so that the limit block 321 is away from the adjacent first rotating shaft 311. The movement of the partition plate 411 will also disengage the plug plate from the slot, thereby releasing the lock on the decorative panel 1.

[0058] In one embodiment of the present invention, another specific example of the locking member 42 is provided, such as Fig.10As shown, the locking member 42 includes a second socket 425, a second plug plate 426 is slidably connected to one side of the second socket 425, a second slot 427 matching with the guide rod 325 or the conical extrusion block 55 is opened on one side of the second plug plate 426, a third inclined surface 428 is provided at the bottom of the second plug plate 426, and a third spring 429 is provided between the second socket 425 and the second plug plate 426;

[0059] When the decorative panel 1 is rotated to complete the assembly, the third inclined surface 428 at the bottom of the second plug plate 426 abuts against the guide rod 325 or the conical extrusion block 55 and is pushed, so that the second plug plate 426 stretches the third spring 429, and then under the reset action of the third spring 429, the second slot 427 is stuck on the surface of the guide rod 325 or the conical extrusion block 55, thereby completing the locking. When unlocking is required, the partition plate 411 is pressed to drive the limit block 321 to move. When the limit block 321 moves, it drives the guide rod 325 and the conical extrusion block 55 to move outside the second slot 427, thereby completing the unlocking.

[0060] It should be noted that since the cross-section of the guide rod 325 and the tapered extrusion block 55 is circular, the second slot 427 can also be set to an approximate semicircular shape. When the guide rod 325 or the tapered extrusion block 55 is located in the second slot 427, the axis of the guide rod 325 or the tapered extrusion block 55 is located within the range of the second slot 427. When the partition 411 is moved to unlock, it is only necessary to make the axis of the guide rod 325 or the tapered extrusion block 55 outside the range of the second slot 427. At this time, the decorative panel 1 can be rotated to completely unlock it.

[0061] In one embodiment of the present invention, the rear end member 32 further includes a corner block 327, such as Figure 8 As shown, the corner block 327 has the same function as the limit block 321, except that the direction of the grooves thereon is different from that of the limit block 321, so as to adapt to wall surfaces that are not in the same plane;

[0062] It should be understood that for walls that are not in the same plane, the corner block 327 may not be used. It is only necessary to install the first rotating shaft 311 for limiting the limit block 321 at the rear end of the slot plate 2. The first rotating shaft 311 is fixedly installed at the rear end of the slot plate 2, and then each wall is installed separately.

[0063] In one embodiment of the present invention, adjacent sound-absorbing decorative panels 1 generally have a certain gap, and the partition 411 can also serve as a separator between two adjacent decorative panels 1, that is, after the decorative panels 1 are assembled, the partition 411 is located between the two adjacent decorative panels 1, and when subsequently disassembled, the decorative panels 1 at the corresponding position can be disassembled by simply pressing the partition 411 from the gap;

[0064] In one embodiment of the present invention, for the installation of the decorative panel 1 that does not require a gap, a shielding groove may be opened on the back side of the decorative panel 1 , and after the assembly is completed, each partition 411 will be hidden under the decorative panel 1 .

[0065] The above only describes some exemplary embodiments of the present invention by way of illustration. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the present invention.
