Description

Technical Field

[0001] This utility model relates to the field of sound-absorbing crystal wood panel installation technology, and in particular to a hidden hanging component for sound-absorbing crystal wood panels. Background Technology

[0002] In the field of architectural acoustic decoration, microporous sound-absorbing panels are widely used due to their excellent sound absorption performance. Their core working principle lies in the numerous tiny pores formed by the aggregation and compression of sand particles inside. These pores can effectively absorb and consume sound wave energy, thereby achieving the function of noise reduction and sound absorption. However, this characteristic of relying on the internal microporous structure places strict requirements on the installation method: any installation behavior that damages the internal structure will directly lead to the blockage of micropores or damage to the structural integrity, thus significantly weakening its sound absorption effect. In traditional installation processes, screw fixing is a common method, but this method requires the screw to penetrate the sound-absorbing panel body, which inevitably punctures the internal sand particle aggregation structure and destroys the continuity of the tiny pores. This not only makes the actual sound absorption effect of the sound-absorbing panel far lower than the design standard, but may also lead to safety hazards such as cracking and falling off of the panel due to structural damage, failing to meet the dual requirements of performance and stability in architectural acoustic decoration.

[0003] To address the shortcomings of traditional installation methods, the industry has gradually explored non-destructive installation technologies. Among them, Chinese patent with announcement number "CN207959664U" discloses a hanging device for microporous sound-absorbing panels. This device innovatively adopts a "corner clamping" fixing approach: through the cooperation of the hanging rod assembly (including screws, locking nuts, locking washers, and clamping washers) and the edge clamping fastener, the edge clamping fastener is clamped at the corner of the microporous sound-absorbing panel, and then the hanging rod assembly is used to achieve hoisting and fixing. This solution successfully avoids penetrating damage to the sound-absorbing panel body, theoretically achieving non-destructive installation, while also possessing the characteristics of decorative beauty and stable installation. It was once regarded as an effective solution to improve the problems of traditional installation.

[0004] However, this patented solution still has significant drawbacks in practical engineering applications. Because it uses a side-clamping fixing method, the clamping fasteners need to be directly attached to and clamped to the side of the sound-absorbing panel. This results in the clamping fasteners being directly exposed on the side of the sound-absorbing panel after installation. From an aesthetic perspective, the exposed metal or plastic clamping fasteners disrupt the overall integrity of the wall or ceiling decoration. Especially in large-area splicing installation scenarios, the exposed side components create obvious visual breaks, severely affecting the overall decorative aesthetics. From an acoustic performance perspective, when multiple sound-absorbing panels are spliced, the side clamping... The presence of fasteners prevents the panels from fitting tightly together, resulting in irregular gaps. These gaps not only become channels for sound wave leakage but also disrupt the uniformity of the sound field, leading to a decrease in the overall sound absorption effect and failing to fully utilize the acoustic advantages of the microporous sound-absorbing panels. It is evident that although existing microporous sound-absorbing panel installation technology has overcome the limitations of traditional destructive installation, it still falls short in meeting the practical application requirements of balancing aesthetics and acoustic performance. Further design optimization is urgently needed to address issues such as exposed side components and splicing gaps, achieving a synergistic unity of non-destructive installation, aesthetic decoration, and efficient sound absorption. Utility Model Content

[0005] To address the aforementioned problems, this utility model proposes a hidden hanging assembly for sound-absorbing crystal wood panels, which more precisely solves the problems described above.

[0006] This utility model is achieved through the following technical solution:

[0007] This utility model proposes a hidden hanging assembly for sound-absorbing crystal wood panels, including a hanging mechanism. A fixed plate is fixedly installed at the bottom of the hanging mechanism, and hanging brackets are fixedly installed on both sides of the fixed plate. A snap-fit ​​mechanism is fixedly installed at the outer end of the hanging bracket, and the sound-absorbing crystal wood panel body is suspended and installed at the outer end of the hanging bracket through the snap-fit ​​mechanism.

[0008] The snap-fit ​​mechanism includes a side frame and a fixing plate. The fixing plate is fixedly installed at the top four corners of the sound-absorbing crystal wood board body. The upper end of the fixing plate has a snap-fit ​​groove. The side frame is fixedly installed at the outer end of the hanger. Both ends of the side frame are fixedly connected to limit snap-fit ​​groups. The outer end of the limit snap-fit ​​group is inserted into the inside of the snap-fit ​​groove.

[0009] Furthermore, the limiting card assembly includes a rail frame, which is fixedly installed at both ends of the side frame. A limiting spring is fixedly connected inside the rail frame, and a slider is fixedly installed at the outer end of the limiting spring. The slider is slidably connected inside the rail frame, and a locking block is fixedly connected to the outer side of the slider. The end of the locking block passes through the rail frame and is inserted into the inside of the locking groove.

[0010] Furthermore, an adjusting pull shaft is fixedly connected to the inner side of the slider, and the end of the adjusting pull shaft passes through the rail frame.

[0011] Furthermore, a detachable adjustment handle is fixedly connected to the inner end of the adjustable pull-out shaft, and an anti-slip handle glove is fixedly connected to the middle of the detachable adjustment handle.

[0012] Furthermore, the lifting mechanism includes a hexagonal sleeve, with a hexagonal sliding rod slidably connected inside the hexagonal sleeve. The bottom of the hexagonal sliding rod is fixedly connected to the top of the fixed plate in the middle. A limit screw is threadedly connected to the lower front end of the sleeve, and the end of the limit screw penetrates through the sleeve.

[0013] Furthermore, the hexagonal slide bar has limit holes arranged linearly at equal intervals on its front side, and the end of the limit screw is inserted into the limit hole. The limit screw is a hand-tightening screw.

[0014] Furthermore, a hanger plate is fixedly installed on the top of the hexagonal sleeve, and mounting holes are arranged in a ring at equal intervals on the bottom of the hanger plate. The mounting holes penetrate the hanger plate and are countersunk holes.

[0015] The beneficial effects of this utility model are:

[0016] 1. During the application of this technical solution, by setting up a hidden structure for the hanging mechanism and the snap-fit ​​mechanism, the hanging plate, hexagonal sleeve, side frame, limit snap-fit ​​group and other components are all arranged on the top of the sound-absorbing crystal wood board body. The fixing plate is fixed to the four corners of the top of the board. The snap-fit ​​operation is completed at the top, so that the connecting components are not visible from the side and bottom during use, avoiding the exposure of components and damage to the overall decoration. At the same time, there is no obstruction structure on the side of the board, and it can be directly attached when splicing without reserving installation space. This achieves the effect of improving the decoration aesthetics and eliminating splicing gaps, solving the problems of exposed side components and splicing gaps affecting the sound absorption performance in the existing technology.

[0017] 2. During the application of this technical solution, the non-through-type installation method with top snap-fit ​​is used to fix the board with the cooperation of the fixing plate and the limiting card group. There is no need to process the sound-absorbing crystal board body through, so that the internal structure of the board will not be damaged during use, thus ensuring the sound absorption performance. At the same time, the hand-tightening limiting screw and the pull-out adjustable handle design make height adjustment and disassembly and assembly without professional tools. The pre-assembly on the ground reduces high-altitude work, thus achieving the effect of non-destructive installation, convenient maintenance and improved installation efficiency. It solves the problems of damage to the board structure and inconvenience of disassembly and maintenance in the existing technology. Attached Figure Description

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Example 1

[0025] A concealed hanging assembly for sound-absorbing crystal wood panels includes a hanging mechanism 1. A fixed plate 5 is fixedly installed at the bottom of the hanging mechanism 1. Hanging brackets 3 are fixedly installed on both sides of the fixed plate 5. A snap-fit ​​mechanism 2 is fixedly installed at the outer end of the hanging brackets 3. The sound-absorbing crystal wood panel body 4 is suspended and installed at the outer end of the hanging brackets 3 through the snap-fit ​​mechanism 2.

[0026] The snap-fit ​​mechanism 2 includes a side frame 21 and a fixing plate 22. The fixing plate 22 is fixedly installed at the top four corners of the sound-absorbing crystal wood panel body 4. The upper end of the fixing plate 22 has a slot 23. The side frame 21 is fixedly installed at the outer end of the hanger. Both ends of the side frame 21 are fixedly connected to limit locking groups 24. The outer ends of the limit locking groups 24 are inserted into the slots 23. During the application of this device, it first provides overall hoisting support through the hoisting mechanism 1. After the connection and fixation with the top of the building is achieved by the hoisting mechanism 1, the fixing plate 5 at the bottom of the hoisting mechanism 1 can transfer the force to the hoisting frames 3 on both sides, so that the hoisting frames 3 maintain a stable support state. Then, the snap-fit ​​mechanism 2 at the outer end of the hoisting frame 3 is used to achieve hoisting and installation with the sound-absorbing crystal wood panel body 4. During the snap-fit ​​process, since the fixing plate 22 is pre-fixed at the top four corners of the sound-absorbing crystal wood panel body 4, and the upper end of the fixing plate 22 has a slot 23, it is only necessary to snap the side frame 21... Align the limiting card groups 24 at both ends with the card slots 23, and then insert the outer ends of the limiting card groups 24 into the card slots 23 to complete the connection between the hanging bracket 3 and the sound-absorbing crystal wood panel body 4. This connection method achieved through the snap-fit ​​mechanism 2 does not require through-processing of the sound-absorbing crystal wood panel body 4 and will not damage the sound-absorbing structure that may exist inside it. This ensures that the sound absorption performance of the sound-absorbing crystal wood panel body 4 is not affected during use, thus achieving the effect of non-destructive installation. At the same time, the fixing plate 22 is set on the top of the sound-absorbing crystal wood panel body 4, and the side frame 21 and the limiting card groups 24 are also connected around the top. All snap-fit ​​related components are not exposed on the sides of the sound-absorbing crystal wood panel body 4, so that when multiple sound-absorbing crystal wood panel bodies 4 are spliced, the sides can be directly attached to avoid splicing gaps, further ensuring the overall sound absorption effect, and the exposed components will not affect the decorative aesthetics, making the overall appearance after installation more complete.

[0027] Combination Figures 3-4 As shown, the limiting bracket 24 includes a rail frame 241, which is fixedly installed at both ends of the side frame 21. A limiting spring 242 is fixedly connected inside the rail frame 241. A slider 243 is fixedly installed at the outer end of the limiting spring 242. The slider 243 is slidably connected inside the rail frame 241. A locking block 244 is fixedly connected to the outer side of the slider 243. The end of the locking block 244 passes through the rail frame 241 and is inserted into the slot 23. An adjusting pull shaft 245 is fixedly connected to the inner side of the slider 243. The end of the adjusting pull shaft 245 passes through the rail frame 241. A disassembly and assembly adjustment handle 246 is fixedly connected to the inner end of the adjusting pull shaft 245. An anti-slip hand glove 247 is fixedly connected to the middle of the disassembly and assembly adjustment handle 246.

[0028] In the above-described embodiments of this application, during the application of this device, when the locking mechanism 2 and the fixed plate 22 are docked, the limiting locking group 24 needs to be operated first. The operator can hold the disassembly and adjustment handle 246 and pull it inward. At this time, the adjustment pull shaft 245, which is fixedly connected to the disassembly and adjustment handle 246, will move synchronously, thereby driving the slider 243, which is fixed to the outside of the adjustment pull shaft 245, to slide inside the rail frame 241. During the sliding of the slider 243, it will compress the limiting spring 242 fixed inside the rail frame 241, so that the limiting spring 242 is in a compressed state. At the same time, the locking block 244 fixed to the outside of the slider 243 will gradually retract into the rail frame 241 as the slider 243 moves, so as to align with the slot 23 of the fixed plate 22 later. When the limiting locking group 24 is aligned with the slot 23, the operator releases the disassembly and adjustment handle 246, and the compressed limiting spring 242 will release its elastic potential energy, pushing the slider 243. 43 slides outward along the rail frame 241, and the slider 243 drives the locking block 244 to move synchronously until the end of the locking block 244 passes through the rail frame 241 and is inserted into the slot 23, completing the locking and fixing. During this process, the anti-slip hand glove 247 in the middle of the handrail 246 can increase the friction between the hand and the handrail, preventing the operator from slipping and affecting the efficiency of operation, and ensuring that the disassembly and assembly process is stable and smooth. The elastic effect of the limit spring 242 can keep the locking block 244 tightly abutting in the slot 23, effectively preventing the locking block 244 from loosening and causing the sound-absorbing crystal wood board body 4 to fall off, improving the stability of the locking structure. At the same time, by adjusting the cooperation of the pull-out shaft 245, slider 243 and limit spring 242, the extension and retraction operation of the locking block 244 can be completed without the need for complicated tools, simplifying the locking and disassembly process. This not only reduces the installation difficulty, but also provides convenience for the subsequent maintenance or replacement of the sound-absorbing crystal wood board body 4, reducing operation time and labor costs.

[0029] Example 2

[0030] Combination Figures 1-3 As shown, the lifting mechanism 1 includes a hexagonal sleeve 11, with a hexagonal slide rod 12 slidably connected inside the hexagonal sleeve 11. The bottom of the hexagonal slide rod 12 is fixedly connected to the top of the fixed plate 5. A limit screw 13 is threadedly connected to the lower end of the front side of the sleeve. The end of the limit screw 13 penetrates the sleeve. Limit holes 14 are linearly arranged at equal intervals on the front side of the hexagonal slide rod 12. The end of the limit screw 13 is inserted into the limit hole 14. The limit screw 13 is a hand-tightening screw. A lifting plate 15 is fixedly installed on the top of the hexagonal sleeve 11. Mounting holes 16 are arranged in a ring at equal intervals on the bottom of the lifting plate 15. The mounting holes 16 penetrate the lifting plate 15 and are countersunk holes.

[0031] In the technical solution described in the above-described embodiments of this application, before the overall hoisting is completed, the device needs to be fixed to the top of the building and its height adjusted by the hoisting mechanism 1. Workers can first use the mounting holes 16 at the bottom of the hoisting plate 15 to connect the hoisting plate 15 to the pre-set installation foundation on the top of the building. External fasteners are then used to pass through the mounting holes 16 to complete the fixation. Since the mounting holes 16 are countersunk holes, the heads of the fasteners can be completely embedded in the holes and will not protrude from the surface of the hoisting plate 15, avoiding interference with subsequent structural connections caused by exposed fasteners. This also ensures the flatness of the connection between the hoisting mechanism 1 and the top of the building, improving the overall aesthetics of the installation. After the hoisting plate 15 is fixed, because the hexagonal sleeve 11 is fixed to the top of the hoisting plate 15 and the hexagonal slide rod 12 is slidably connected inside the hexagonal sleeve 11, workers can push or pull the hexagonal slide rod 12 along the axial direction of the hexagonal sleeve 11 according to the actual installation height requirements, adjusting the length of the hexagonal slide rod 12 extending out of the hexagonal sleeve 11 until the bottom of the hexagonal slide rod 12 is fixed. When the fixed plate 5 reaches the preset height, the hexagonal structure of the hexagonal sleeve 11 and the hexagonal slide rod 12 effectively prevents relative rotation during adjustment, ensuring that the fixed plate 5 remains horizontal. This lays the foundation for the stable installation of the subsequent hanging bracket 3 and the sound-absorbing crystal wood panel body 4. Once the height is adjusted to the correct position, the operator can directly rotate the limiting screw 13 at the lower front of the hexagonal sleeve 11 by hand. Since the limiting screw 13 is a hand-tightening screw, it can be operated without the need for additional tools. The adjustment convenience is greatly improved. As the limiting screw 13 rotates, its end will gradually pass through the sleeve and insert into the limiting hole 14 on the front of the hexagonal slide rod 12. By engaging the limiting screw 13 with the limiting hole 14, the relative position of the hexagonal slide rod 12 and the hexagonal sleeve 11 is locked, preventing the hexagonal slide rod 12 from sliding due to force during subsequent use. This ensures the overall height stability of the lifting mechanism 1 and further ensures the positional accuracy of the sound-absorbing crystal wood panel body 4 after installation, preventing the effect of use due to height deviation.

[0032] The working principle and advantages of this utility model are as follows: First, the installation and height adjustment of the hoisting mechanism 1 of this device are carried out. This is the basis for the subsequent hoisting of the sound-absorbing crystal wood panel body 4. During operation, the hoisting plate 15 in the hoisting mechanism 1 is first aligned with the preset installation base on the top of the building. By using the mounting holes 16 arranged in a ring at the bottom of the hoisting plate 15, and with the help of external fasteners passing through the mounting holes 16, the hoisting plate 15 is fixed to the top of the building. By setting the mounting holes 16 as countersunk holes, the heads of the fasteners can be embedded in the holes during use, avoiding the fasteners protruding and affecting the structural connection, thereby ensuring the flatness of the connection between the hoisting mechanism 1 and the top of the building. After the hoisting plate 15 is fixed, its bottom is fixedly connected to the hexagonal sleeve 11, and the hexagonal sleeve 11 has a sliding interior. A hexagonal slide rod 12 is movably connected. By sliding the hexagonal slide rod 12 axially along the hexagonal sleeve 11, its position can be adjusted according to the actual installation height requirements during use until the fixed plate 5 connected to the bottom of the hexagonal slide rod 12 reaches the preset height. The hexagonal structure of the hexagonal sleeve 11 and the hexagonal slide rod 12 cooperates to prevent relative rotation between the two during use, thus providing stability for subsequent structural installation. After the hexagonal slide rod 12 is adjusted to the target height, the limiting screw 13 threaded to the lower front end of the hexagonal sleeve 11 is rotated. The rotation of the limiting screw 13 allows its end to pass through the hexagonal sleeve 11 and insert into the limiting hole 14 on the front of the hexagonal slide rod 12 during use. The cooperation of the two restricts the hexagonal slide rod. 12. Sliding mechanism 1 achieves height fixation. By setting the limiting screw 13 as a hand-tight screw, adjustment can be completed without additional tools during use, greatly improving operational convenience. This design also lays the foundation for the precise hoisting of the sound-absorbing crystal board body 4, avoiding the impact of height deviation on the installation effect. After completing the installation and adjustment of the hoisting mechanism 1, the assembly stage of the snap-fit ​​mechanism 2 and the sound-absorbing crystal board body 4 begins. Preparations must be made in advance to ensure smooth hoisting. Before hoisting the sound-absorbing crystal board body 4, the fixing plate 22 in the snap-fit ​​mechanism 2 is fixedly installed at the top four corners of the sound-absorbing crystal board body 4. By setting the fixing plate 22, the sound-absorbing crystal board body can be secured during use. Body 4 provides a force-bearing point for connection with the hanger 3. Since the fixing plate 22 is installed at the top corner, it avoids the need for connection structures on the side of the sound-absorbing crystal wood panel body 4 during use. This fundamentally solves the problem of exposed components in traditional side-mounting methods, creating conditions for improving decorative aesthetics and eliminating splicing gaps. After the fixing plate 22 is installed, the adjusting pull-out shafts 245 at both ends of the outer side frame 21 of the hanger 3 are operated. Since the inner end of the adjusting pull-out shaft 245 is connected to the disassembly and assembly adjustment handle 246, and the outer end passes through the rail frame 241 and is fixedly connected to the inner side of the slider 243, pulling the disassembly and assembly adjustment handle 246 outwards allows the adjusting pull-out shaft 245 and slider 243 to slide along the inside of the rail frame 241 during use.Simultaneously, the limiting spring 242 fixedly connected inside the compression rail frame 241 causes the locking block 244 fixedly connected to the outside of the slider 243 to move with the slider 243, its end retracting into the rail frame 241, preparing for subsequent docking with the slot 23 of the fixing plate 22. By setting an anti-slip handgrip 247 in the middle of the disassembly and assembly adjustment handrail 246, the friction between the hand and the handrail is increased during use, preventing slippage during operation, thereby further improving the safety and convenience of the assembly process and ensuring that all components of the locking mechanism 2 are in a ready-to-be-connected state.

[0033] Lift the sound-absorbing crystal wood panel 4 with the pre-installed fixing plate 22, aligning the slot 23 at the upper end of the fixing plate 22 with the limiting locking group 24 at both ends of the side frame 21. The limiting locking group 24 consists of a rail frame 241, a limiting spring 242, a slider 243, and a locking block 244. After alignment, release the previously pulled disassembly and adjustment handle 246. The pushing force generated by the limiting spring 242 under the elastic restoring force allows the slider 243 to slide inward along the rail frame 241 during use. The slider 243 drives the locking block 244 to move synchronously, thus enabling the locking block to move inward. The end of the 244 block penetrates the rail frame 241 and inserts into the slot 23 of the fixing plate 22. After the 244 block is inserted into the slot 23, the limiting spring 242 continuously applies an inward elastic force to the slider 243, ensuring that the 244 block remains in the slot 23 during use, thus achieving the snap-fit ​​fixation between the side frame 21 and the fixing plate 22. Since the hanging frame 3 is connected to the hanging mechanism 1 through the fixing plate 5, the sound-absorbing crystal wood panel body 4 is finally installed by the snap-fit ​​mechanism 2 and the hanging frame 3. Moreover, the entire snap-fit ​​process does not require any through-processing of the sound-absorbing crystal wood panel body 4, and will not... By disrupting the sand-like aggregate structure that may exist inside the sound-absorbing crystal board, this non-penetrating installation design ensures that the sound absorption performance of the sound-absorbing crystal board body 4 is not affected by the installation during use, thus maintaining the advantage of non-destructive installation. It also avoids the safety hazards such as cracking and detachment of the board that may occur with traditional screw-through installation. After the sound-absorbing crystal board body 4 is hoisted and installed, this technical solution also has many significant advantages from the perspective of overall usage effect and subsequent maintenance. In terms of decorative aesthetics and sound absorption effect, the core component of the snap-fit ​​mechanism 2 of this device... The system includes a side frame 21, a limiting bracket 24, and a fixing plate 22. These components are all located on the top of the sound-absorbing crystal wood panel body 4. The fixing plate 22 is fixed to the top corner. The side frame 21 is fixed to the outer end of the hanging bracket 3 and is located above the sound-absorbing crystal wood panel body 4. The limiting bracket 24 is installed at both ends of the side frame 21 and is connected to the fixing plate 22 at the top. By hiding all the connecting components on the top of the sound-absorbing crystal wood panel body 4, the connecting components cannot be seen when viewed from below or the side during use. This avoids the problem of exposed components damaging the overall decoration in the traditional side installation method.Meanwhile, since the connection structure of the sound-absorbing crystal wood panel body 4 is only located at the top, with no protrusions or obstructing components on the sides, this structural design allows adjacent sides to be directly fitted together when multiple panels are spliced ​​during use, eliminating the need for pre-reserved installation space. This effectively eliminates splicing gaps, preventing sound waves from leaking through the gaps and ensuring the overall sound absorption effect. Regarding ease of installation and maintenance and structural stability, the device includes a lifting mechanism 1, a snap-fit ​​mechanism 2, and the sound-absorbing crystal wood panel body 4. By pre-assembling these structures on the ground, only fixing the lifting mechanism 1, adjusting its height, and snap-fitting are required on-site during use, thus reducing the time spent working at heights. Furthermore, the hand-tightening design of the limiting screw 13 and the detachable and adjustable handle 246 allow for direct... The manual operation eliminates the need for specialized tools during use, thus reducing installation difficulty. When it is necessary to replace or maintain the sound-absorbing crystal wood panel body 4, simply pull the disassembly and adjustment handle 246 again to retract the locking block 244 back to the rail frame 241, thereby disengaging the locking connection and removing the panel, avoiding secondary damage. In addition, through the anti-rotation cooperation of the hexagonal sleeve 11 and hexagonal slide rod 12 in the lifting mechanism 1, the height locking of the limiting screw 13 and the limiting hole 14, the continuous pressure of the locking block 244 by the limiting spring 242 in the locking mechanism 2, and the fixed connection of the fixing plate 22 to the four corners of the sound-absorbing crystal wood panel body 4, a multi-dimensional force balance can be formed during use, thereby effectively distributing the weight of the panel, avoiding deformation or detachment caused by single-point force, and improving the overall installation stability.

[0034] Of course, there may be other implementations of this utility model. Based on this implementation, other implementations obtained by those skilled in the art without any creative effort are all within the scope of protection of this utility model.
