Description

Technical Field

[0001] This utility model belongs to the field of sound-absorbing panel technology, specifically relating to a wall-mounted decorative sound-absorbing panel. Background Technology

[0002] Acoustic panels are materials specifically designed to reduce indoor echoes and noise. They are widely used in places with high acoustic requirements, such as theaters, concert halls, museums, libraries, stadiums, hotels, hospitals, schools, and recording studios.

[0003] Existing sound-absorbing panels are installed by drilling holes in the wall, installing expansion bolts in the holes, and then fixing them with multiple screws. When installing multiple perforated sound-absorbing wall panels, a lot of time is required to drill holes and use a large number of screws to fix the perforated sound-absorbing wall panels. This makes the installation process extremely troublesome due to the large number of screws and holes, which reduces installation efficiency. Furthermore, the use of a large number of screws for fixing also greatly affects the aesthetics of the sound-absorbing panels.

[0004] Therefore, in order to address the aforementioned technical problems, it is necessary to provide a wall-mounted sound-absorbing panel.

[0005] The information disclosed in this background section is intended only to enhance the understanding of the overall background of this utility model and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art. Utility Model Content

[0006] The purpose of this utility model is to provide a wall-mounted sound-absorbing panel that can solve the problem that the installation of existing sound-absorbing panels requires a large number of screws, resulting in low installation efficiency and affecting aesthetics.

[0007] To achieve the above objectives, the technical solution provided by a specific embodiment of this utility model is as follows:

[0008] A wall-mounted sound-absorbing panel includes: an outer shell, an outer panel, a mounting mechanism, and a clamping assembly.

[0009] The outer casing contains a sound-absorbing layer. The outer panel is slidably mounted on the outer casing and is located outside the sound-absorbing layer, fitting snugly against it. Multiple strip-shaped sound-absorbing holes are drilled in the outer panel.

[0010] The mounting mechanism is installed between an outer shell and includes a keel, multiple snap-fit ​​parts, multiple snap-fit ​​members, and a cover plate. The keel is installed on one side of the outer shell and fits tightly against it. Multiple snap-fit ​​parts are evenly cut into the side walls of the outer shell. Multiple snap-fit ​​members slide within the keel, with their ends respectively engaging the snap-fit ​​parts on the two outer shells. The cover plate is secured in the keel, and its outer surface covers the edges of the two outer shells, flush with the outer panel. Multiple locking grooves are fixed in the keel, and multiple pairs of claws are fixed to the inner surface of the cover plate, with one pair of claws engaging in the locking grooves.

[0011] The locking assembly slides in the locking groove to lock the engagement state of a pair of claws and the locking groove.

[0012] In one embodiment of this utility model, the sound-absorbing layer comprises: a polyester fiber layer, a damping sound-insulating felt, and a glass fiber layer. The damping sound-insulating felt is disposed between the polyester fiber layer and the glass fiber layer, and the glass fiber layer is bonded to the outer panel. The polyester fiber layer, the damping sound-insulating felt, and the glass fiber layer contain a large number of tiny, interconnected pores, which allow sound waves to penetrate deep into the material to achieve a sound absorption effect.

[0013] In one embodiment of this utility model, a retaining plate is fixed to both sides of the outer panel, and a sliding groove adapted to the retaining plate is cut into the outer shell, and the retaining plate slides in the sliding groove. The outer panel is slidably installed in the sliding groove by the retaining plate, thereby being installed on the outer shell.

[0014] In one embodiment of this utility model, a plurality of screws are fixed between the slide groove and the outer shell. After the outer panel is slidably installed on the outer shell, it is fixed on the outer shell by the screws.

[0015] In one embodiment of this utility model, the snap-fit ​​part includes a U-shaped groove and a slot. The U-shaped groove is carved into the side wall of the outer shell, and the slot is carved into the inner side wall of the U-shaped groove. The U-shaped groove is used for the sliding rod to drive the snap-fit ​​head into the keel along the U-shaped groove, and the slot is used for the snap-fit ​​head to be locked in it, thereby preventing the snap-fit ​​head from sliding out of the slot and thus preventing loosening between the outer shell and the keel.

[0016] In one embodiment of this utility model, the bottom opening of the U-shaped groove is provided with a snap-fit ​​angle and a flared portion. The snap-fit ​​angle is used to pull the snap-fit ​​head towards the outer shell when it enters the slot, making it easier for the snap-fit ​​head to snap into the slot. The flared portion is used to make it easier for the slide rod to slide into the U-shaped groove.

[0017] In one embodiment of this utility model, the snap-fit ​​component includes: a pair of slide rods, two pairs of snap heads, a connecting rod, and a pair of first springs. The pair of slide rods slides along both sides of the keel. The two pairs of snap heads are respectively fixed to both ends of the pair of slide rods, and the two snap heads at one end of each slide rod inside the keel are mutually engaged. The connecting rod slides within the pair of slide rods, and both ends of the connecting rod within the pair of slide rods are fixed with limiting heads. The pair of first springs are respectively installed at both ends of the connecting rod, and are both located between the limiting heads and the inner walls of the slide rods.

[0018] A pair of sliding rods are elastically connected by a connecting rod. When the sliding rod drives the locking head to slide from the U-shaped groove into the side wall of the keel, the angled engagement pushes the locking head towards the outer casing. The locking head drives the sliding rod to move, compressing the first spring as it moves. When the locking head reaches the slot, the rebound force of the first spring pushes the sliding rod and the locking head in the opposite direction, causing the locking head to engage in the slot. After the outer casings are installed on both sides of the keel, the connecting rod, through a pair of first springs, pulls the pair of sliding rods closer together, so that the locking heads at both ends of the pair of sliding rods are engaged in the slots on both sides, thus fixing the outer casing.

[0019] In one embodiment of this utility model, a plurality of limiting clips are fixed on the inner side of the cover plate, and the limiting clips are grooved to fit a pair of clip heads. When the cover plate is fastened to the keel, the limiting clips engage with the two clip heads of a pair of sliding rods located at one end of the keel, thereby preventing the pair of sliding rods from sliding and preventing the clip heads at both ends from sliding out of the slots, thus locking the outer shell to the keel.

[0020] In one embodiment of this utility model, the locking assembly includes a limiting block and a second spring. The limiting block slides in the locking groove and has a pair of ear plates on both sides; the second spring is installed between the limiting block and the bottom wall of the locking groove. When the pair of claws are inserted into the locking groove, the claws first retract inward into the locking groove. As the claws move downward, they push the limiting block downward. After the claws move into the locking groove, their bottom ends spread out to both sides and move away from the top of the limiting block. At this time, the elastic force of the second spring pushes the limiting block upward, causing the limiting block to lock between the claws. The pair of connecting rods are respectively positioned at the bottom of the claws, thereby locking the claws in the locking groove and locking the cover plate on the cover plate. The pair of ear plates also prevent the elastic force of the second spring from pushing the limiting block out of the locking groove.

[0021] In one embodiment of this utility model, the limiting block is provided with inwardly inclined inclined side areas at both top corners of its two sides, so that when the second spring pushes the limiting block upward, the limiting block can slide more easily between a pair of claws.

[0022] Compared with existing technologies, the wall-mounted sound-absorbing panel of this utility model, through its related structural design, effectively improves the installation efficiency and aesthetics of the sound-absorbing panel after installation. Attached Figure Description

Detailed Implementation

[0034] To enable those skilled in the art to better understand the technical solutions in this disclosure, the technical solutions in the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this disclosure, and not all embodiments. Based on the embodiments in this disclosure, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of this disclosure.

[0035] like Figures 1 to 8 As shown, a wall-mounted sound-absorbing panel according to one embodiment of the present invention includes: an outer shell 1, an outer panel 101, an installation mechanism 2, and a clamping assembly 216.

[0036] like Figures 1 to 2 As shown, a sound-absorbing layer 103 is provided inside the outer casing 1. The outer panel 101 is slidably mounted on the outer casing 1 and is located outside the sound-absorbing layer 103 and is in contact with the sound-absorbing layer 103. Multiple strip-shaped sound-absorbing holes 102 are drilled on the outer panel 101.

[0037] like Figures 1 to 4 As shown, the mounting mechanism 2 is installed between an outer shell 1. The mounting mechanism 2 includes: a keel 201, multiple snap-fit ​​parts 203, multiple snap-fit ​​pieces 204, and a cover plate 202. The keel 201 is installed on one side of the outer shell 1 and fits tightly against it. The multiple snap-fit ​​parts 203 are evenly cut into the side wall of the outer shell 1. The multiple snap-fit ​​pieces 204 slide in the keel 201, and their two ends are respectively snapped into the snap-fit ​​parts 203 on the two outer shells 1. The cover plate 202 is snapped into the keel 201, and its outer side covers the edges of the two outer shells 1 and is flush with the outer panel 101. Multiple locking grooves 215 are fixed in the keel 201, and multiple pairs of claws 217 are fixed on the inner side of the cover plate 202, with one pair of claws 217 snapping into the locking grooves 215.

[0038] like Figures 1 to 2As shown, the locking assembly 216 slides in the locking groove 215 to lock the engagement state of the pair of claws 217 and the locking groove 215.

[0039] During installation, multiple keels 201 are first bolted to the wall according to the width of the outer casing 1. Then, the outer casing 1 is installed between every two keels 201. The snap-fit ​​pieces 204 on both sides of the keel 201 snap into the snap-fit ​​parts 203 on the side wall of the outer casing 1, thus securing the outer casing 1. Next, the keels 201 are snapped onto the outer casing 1, so that their outer surfaces cover the edges of the outer casing 1 on both sides and are flush with the outer panel 101. The keels 201 are secured to the outer casing 201 by a pair of claws 217 engaging in the locking groove 215. Furthermore, the locking assembly 216 locks the engagement of the claws 217 and the locking groove 215, thereby locking the cover plate 202 within the keels 201.

[0040] When in use, sound enters the outer shell 1 through the strip-shaped sound-absorbing holes 102, and then is absorbed by the sound-absorbing layer 103.

[0041] like Figures 1 to 2 As shown, the sound-absorbing layer 103 includes a polyester fiber layer 104, a damping sound-insulating felt 105, and a glass fiber layer 106. The damping sound-insulating felt 105 is disposed between the polyester fiber layer 104 and the glass fiber layer 106, and the glass fiber layer 106 is bonded to the outer panel 101. The polyester fiber layer 104, the damping sound-insulating felt 105, and the glass fiber layer 106 contain a large number of tiny, interconnected pores, which allow sound waves to penetrate deep into the material to achieve a sound absorption effect.

[0042] like Figures 1 to 2 As shown, both sides of the outer panel 101 are fixed with retaining plates 108. The outer casing 1 has grooves 107 that fit the retaining plates 108, and the retaining plates 108 slide within the grooves 107. The outer panel 101 is slidably mounted on the outer casing 1 via the retaining plates 108 within the grooves 107. Multiple screws 109 are fixed between the grooves 107 and the outer casing 1. After the outer panel 101 is slidably mounted on the outer casing 1, it is secured to the outer casing 1 by the screws 109.

[0043] like Figures 2 to 3As shown, the locking part 203 includes a U-shaped groove 205 and a locking slot 206. The U-shaped groove 205 is carved into the side wall of the outer shell 1, and the locking slot 206 is carved into the inner side wall of the U-shaped groove 205. The U-shaped groove 205 is used for the slide rod 209 to drive the locking head 210 into the keel 201 along the U-shaped groove 205, and the locking slot 206 is used for the locking head 210 to be locked in it, thereby preventing the locking head 210 from sliding out of the locking slot 206, thereby preventing loosening between the outer shell 1 and the keel 201. The bottom opening of the U-shaped groove 205 is provided with a locking bevel 207 and a flared part 208. The locking bevel 207 is used to pull the locking head 210 towards the outer shell 1 when the locking head 210 enters the locking slot 206, making it easier for the locking head 210 to be locked into the locking slot 206. The flared part 208 is used to make it easier for the slide rod 209 to slide into the U-shaped groove 205 when it slides into the U-shaped groove 205.

[0044] like Figures 4 to 7 As shown, the snap-fit ​​component 204 includes: a pair of slide rods 209, two pairs of snap heads 210, a connecting rod 211, and a pair of first springs 213. The pair of slide rods 209 slide on both sides of the keel 201. The two pairs of snap heads 210 are respectively fixed to both ends of the pair of slide rods 209, and the two snap heads 210 located at one end of each slide rod 209 are mutually engaged. The connecting rod 211 slides within the pair of slide rods 209, and both ends of the connecting rod 211 located within the pair of slide rods 209 are fixed with limiting heads 212. The pair of first springs 213 are respectively installed at both ends of the connecting rod 211, and are both located between the limiting heads 212 and the inner wall of the slide rod 209.

[0045] Specifically, a pair of sliding rods 209 are elastically connected by a connecting rod 211. When the sliding rod 209 drives the locking head 210 to slide from the U-shaped groove 205 into the side wall of the keel 201, the pushing force of the locking angle 207 causes the locking head 210 to move towards the outer shell 1. The locking head 210 drives the sliding rod 209 to move, and the sliding rod 209 compresses the first spring 213 as it moves. When the locking head 210 moves to the locking groove 206, the rebound force of the first spring 213 pushes the sliding rod 209 and the locking head 210 in the opposite direction, causing the locking head 210 to engage in the locking groove 206. After the outer shell 1 is installed on both sides of the keel 201, the connecting rod 211 pulls the pair of sliding rods 209 closer together through a pair of first springs 213, so that the locking heads 210 at both ends of the pair of sliding rods 209 are engaged in the locking grooves 206 on both sides, thereby fixing the outer shell 1.

[0046] like Figures 4 to 7As shown, multiple limiting clips 214 are also fixed on the inner side of the cover plate 202. The limiting clips 214 have grooves that are adapted to a pair of clip heads 210. When the cover plate 202 is locked onto the keel 201, the limiting clips 214 lock onto the two clip heads 210 located at one end of a pair of sliding rods 209 inside the keel 201, thereby preventing the pair of sliding rods 209 from sliding and preventing the clip heads 210 at both ends from sliding out of the slots 206, thus locking the outer shell 1 and the keel 201.

[0047] like Figure 4 and 8 As shown, the locking assembly 216 includes a limiting block 218 and a second spring 219. The limiting block 218 slides in the locking groove 215 and has a pair of ear plates 221 on both sides; the second spring 219 is installed between the limiting block 218 and the bottom wall of the locking groove 215. When a pair of claws 217 are inserted into the locking groove 215, the claws 217 will first retract inward into the locking groove 215. As the claws 217 move downward, they push the limiting block 218 downward. After the claws 217 move into the locking groove 215, their bottom ends open to both sides and move away from the top of the limiting block 218. At this time, the elastic force of the second spring 219 pushes the limiting block 218 upward, causing the limiting block 218 to lock between a pair of claws 217. The pair of connecting rods 211 are respectively positioned at the bottom of the pair of claws 217, thereby locking the claws 217 in the locking groove 215, thus locking the cover plate 202 onto the cover plate 202. The pair of ear plates 221 also serve to prevent the elastic force of the second spring 219 from pushing the limiting block 218 out of the locking groove 215.

[0048] like Figure 8 As shown, the limit block 218 has inwardly inclined inclined side areas 220 at both top corners, so that when the second spring 219 pushes the limit block 218 upward, the limit block 218 can slide more easily between a pair of claws 217.

[0049] Working principle: Before installing the sound-absorbing panel, the sound-absorbing layer 103 is first installed in the outer shell 1. Then, the retaining plates 108 on both sides of the outer panel 101 are slid into the outer shell 1 along the sliding groove 107 and fixed with screws 109. During installation, according to the width of the outer shell 1, multiple keels 201 are first fixed to the wall with bolts. Then, the outer shell 1 is installed between every two keels 201.

[0050] When the slide rod 209 drives the locking head 210 to slide from the U-shaped groove 205 into the side wall of the keel 201, the pushing force of the locking angle 207 will cause the locking head 210 to move towards the outer shell 1. The locking head 210 drives the slide rod 209 to move. When the slide rod 209 moves, it compresses the first spring 213. When the locking head 210 moves to the locking groove 206, the rebound force of the first spring 213 pushes the slide rod 209 and the locking head 210 in the opposite direction, so that the locking head 210 is locked in the locking groove 206. After the outer shell 1 is installed on both sides of the keel 201, the connecting rod 211 pulls the pair of slide rods 209 closer to each other through the pair of first springs 213, so that the locking heads 210 at both ends of the pair of slide rods 209 are locked in the locking grooves 206 on both sides, thereby fixing the outer shell 1.

[0051] Then, the keel 201 is snapped onto the outer shell 1, so that its outer side covers the edges of the outer shell 1 on both sides and is flush with the outer panel 101. The keel 201 is secured to the outer shell 1 by a pair of claws 217 in the locking groove 215. In addition, the limiting clips 214 are secured to the two clips 210 at one end of a pair of sliding rods 209, which are respectively located inside the keel 201, thereby preventing the pair of sliding rods 209 from sliding and preventing the clips 210 at both ends from sliding out of the slots 206, thus locking the outer shell 1 and the keel 201.

[0052] Simultaneously, when a pair of claws 217 are inserted into the locking groove 215, the claws 217 will first retract inward into the locking groove 215. As the claws 217 move downward, they push the limiting block 218 downward. After the claws 217 move into the locking groove 215, their bottom ends open to both sides and move away from the top of the limiting block 218. At this time, the elastic force of the second spring 219 pushes the limiting block 218 upward, so that the limiting block 218 is locked between the claws 217. The pair of connecting rods 211 are respectively lowered at the bottom of the claws 217, thereby locking the claws 217 in the locking groove 215, thus locking the cover plate 202 onto the cover plate 202.

[0053] When in use, sound enters the outer shell 1 through the strip-shaped sound-absorbing holes 102, and then is absorbed by the sound-absorbing layer 103.
