Description

Technical Field

[0001] This invention relates to the field of noise shielding technology, and more specifically to a high-efficiency sound-absorbing and noise-reducing board. Background Technology

[0002] Sound-absorbing and noise-reducing panels are divided into indoor panels and outdoor panels. Indoor panels rely on the combination of polyester sound-absorbing cotton and sound insulation layers to achieve sound absorption and noise reduction capabilities, and are often used in noisy places such as bars and KTVs.

[0003] According to patent number CN106816145A, published on June 9, 2017, a composite noise reduction board and noise reduction device are disclosed. The composite noise reduction board includes a sound-absorbing layer and a metal sound-insulating layer. The sound-absorbing layer has sound-absorbing pores, and the metal sound-insulating layer has a C-shaped cross-section. The sound-absorbing layer is embedded within the cavity of the C-shaped structure of the metal sound-insulating layer. By using a metal sound-insulating layer with a C-shaped structure to insulate the noise source, and by absorbing the noise through the sound-absorbing layer with sound-absorbing pores within the cavity of the C-shaped structure of the metal sound-insulating layer, efficient sound absorption and noise reduction treatment of the noise source is achieved. This noise reduction board has a simple structure, is economical and environmentally friendly, easy to assemble, and has a wide range of applications.

[0004] In the prior art, including the aforementioned patents, sound-absorbing and noise-reducing panels are mostly fixed to the wall by adhesive. However, adhesive bonding can easily create gaps between adjacent sound-absorbing and noise-reducing panels. In places where there is no light, such as bars and KTVs, humid air can easily seep into the adhesive bonding area, causing it to age and reduce the bonding effect, making it easy for the sound-absorbing and noise-reducing panels to fall off the wall. Summary of the Invention

[0005] The purpose of this invention is to provide a high-efficiency sound-absorbing and noise-reducing board, which aims to solve the problem that sound-absorbing and noise-reducing boards are prone to falling off the wall due to aging.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a high-efficiency sound absorption and noise reduction board, comprising:

[0007] Plate frame;

[0008] A sealing connection mechanism includes multiple buckle groups arranged in a circumferential array on the plate frame, wherein each buckle group includes a symmetrical semi-circular arc plate;

[0009] The semi-circular arc clamp is driven to clamp the other semi-circular arc clamp on the plate frame to fill the gap between the two plate frames.

[0010] Preferably, the sealing connection mechanism further includes a sealing ring, which is sleeved between the two semi-circular arc plates, and one of the sealing rings is deformed by drive to fit the other sealing ring.

[0011] Preferably, the sealing ring has symmetrically formed retaining grooves, and the two semi-circular retaining plates are driven to engage with the retaining grooves of the other sealing ring.

[0012] Preferably, the semi-circular arc plate is provided with symmetrical snap-fit ​​thin-walled grooves, and the first end of one of the semi-circular arc plates is driven to snap into the snap-fit ​​thin-walled groove of the other semi-circular arc plate.

[0013] Preferably, the semi-circular arc plate is symmetrically provided with snap-fit ​​thin-walled grooves, and when the two plate frames are driven to be parallel to each other, the semi-circular arc plate operates along the following three positions:

[0014] First station: The semi-circular arc plate is driven to bend, so as to drive another semi-circular arc plate to move closer to the center of the two semi-circular arc plates;

[0015] Second station: One of the semi-circular arc plates on one of the plate frames is driven to slide along the outer wall of one of the semi-circular arc plates on the other plate frame into the inner wall of the semi-circular arc plate;

[0016] Third station: Two semi-circular arc clamping plates on one of the two semi-circular arc clamping plates on the other plate frame.

[0017] Preferably, the two semi-circular arc plates are slidably connected by a flexible connecting part, and the two ends of the flexible connecting part are respectively fixedly connected to the first ends of the two semi-circular arc plates.

[0018] Preferably, a hollow layer is provided inside the plate frame.

[0019] Preferably, a sealing ring is fitted on the side wall of the plate frame, and the sealing ring is fixedly connected to the hollow layer.

[0020] Preferably, the sealing ring has a concave-convex mating portion and a venting portion. The sealing ring is deformed by being driven and squeezed to cause the concave-convex mating portion to protrude and fit against the concave-convex mating portion on another sealing ring, so that the two sealing rings are connected.

[0021] Preferably, the plate frame is provided with a sound insulation component, which includes a sound-absorbing cotton board and a nylon sound insulation board respectively disposed on the plate frame.

[0022] In the above technical solution, the present invention provides a high-efficiency sound absorption and noise reduction board with the following beneficial effects: symmetrical semi-circular arc plates are provided on the side of the board frame. When docking, the two semi-circular arc plates on one board frame can be directly clamped onto the two semi-circular arc plates on the other board frame, which can enhance the connection between the board frames and the board frames. This will prevent a single board frame from falling off by being pulled by the surrounding board frames. In addition, the docking semi-circular arc plates also have a certain sealing effect, which can eliminate the gap between the two board frames and slow down the aging of the adhesive.

[0033] To make the objectives, technical solutions, and advantages of the embodiments of this disclosure clearer, the technical solutions of 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, not all, of the embodiments of this disclosure. All other embodiments obtained by those skilled in the art based on the described embodiments of this disclosure without creative effort are within the scope of protection of this disclosure.

[0034] like Figure 1-7 As shown, a high-efficiency sound absorption and noise reduction board includes:

[0035] Plate frame 1;

[0036] The sealing connection mechanism 3 includes multiple buckle groups arranged in a circumferential array on the plate frame 1, and the buckle groups include symmetrical semi-circular arc buckle plates 31.

[0037] The semi-circular arc clamp 31 is driven to clamp the semi-circular arc clamp 31 on another plate frame 1 to fill the gap between the two plate frames 1.

[0038] Specifically, during installation, first apply adhesive (adhesive strips or glue) to one side of the wall panel frame 1. Then, starting from the bottom of the wall, install the first panel frame 1, attaching it to the wall. Next, hold the second panel frame 1 at an angle and align its semi-circular locking plate 31 with the two semi-circular locking plates 31 on the first panel frame 1 to complete the alignment. Then, flip the panel frame 1 so that the adhesive-coated side is in contact with the wall to complete the adhesion. Then, install the wall panel frames 1 sequentially, creating two sets of symmetrical semi-circular... The snap-fit ​​plate 31 enhances the connection between the two plate frames 1. When a single plate frame 1 falls off, it is pulled by the surrounding plate frames 1 to prevent it from falling. It also prevents the adhesive from aging and falling off a single plate frame 1, which could threaten people in the room. Furthermore, the semi-circular snap-fit ​​plate 31 has a certain sealing effect, which can eliminate the gap between the two plate frames 1, reduce the contact of humid gas with the adhesive, and thus slow down the aging of the adhesive. After the two sets of semi-circular snap-fit ​​plates 31 are snapped together, the plate frame 1 can be held by hand and rotated or slid along the snap-fit ​​position for fine-tuning of the installation position.

[0039] In the above technical solution, symmetrical semi-circular arc clamping plates 31 are provided on the side of the plate frame 1. During the docking, the two semi-circular arc clamping plates 31 on one plate frame 1 can be directly clamped onto the two semi-circular arc clamping plates 31 on the other plate frame 1. This can enhance the connection between the plate frames 1 and the plate frames 1, so that if a single plate frame 1 falls off, it will be pulled by the surrounding plate frames 1 to prevent it from falling. In addition, the docking semi-circular arc clamping plates 31 also have a certain sealing effect, which can eliminate the gap between the two plate frames 1 and slow down the aging of the adhesive.

[0040] As an embodiment of the present invention, the sealing connection mechanism 3 further includes a sealing ring 33, which is sleeved between two semi-circular arc plates 31, and one sealing ring 33 is deformed by driving to fit the other sealing ring 33.

[0041] Specifically, the sealing ring 33 is a complete circular ring, which is fixed to the side of the plate frame 1 and set between two semi-circular arc plates 31 so that the sealing ring 33 is molded into the shape of the plate frame 1.

[0042] During installation, first apply adhesive (adhesive strip or glue) to one side of the panel frame 1 to be pasted onto the wall. Then, starting from the bottom of the wall, install the first panel frame 1, pasting it onto the wall. Next, hold the second panel frame 1 at an angle and align its semi-circular locking plate 31 with the two semi-circular locking plates 31 on the first panel frame 1 to complete the mating installation. At this point, the mating semi-circular locking plates 31 also have a certain sealing effect, eliminating gaps between the two panel frames 1, reducing the contact of moisture with the adhesive, thereby slowing down the aging of the glue. Furthermore, the sealing ring 33 inside the second panel frame 1 will be compressed and deformed, moving closer to the sealing ring 33 on the first panel frame 1, so that... Two sealing rings 33 come into contact to achieve a sealing effect, further isolating the room from humid air and slowing down the aging time of the adhesive. Then, the panel frame 1 is flipped so that the side covered with adhesive is attached to the wall to complete the installation. Next, the wall panel frame 1 is laid and installed in sequence. The two sets of symmetrical semi-circular arc plates 31 can strengthen the connection between the panel frames 1 and the panel frames 1. If a single panel frame 1 falls off, it will be pulled by the surrounding panel frames 1 to prevent it from falling off. It can prevent the people in the room from being threatened by the aging of the adhesive on a single panel frame 1. After the two sets of semi-circular arc plates 31 are engaged, the panel frame 1 can also be held by hand and flipped or slid along the engagement position for fine adjustment of the installation position.

[0043] In the above embodiments, the structure that drives the sealing ring 33 to be squeezed and deformed can be an airbag disposed inside the semi-circular plate 31. When in use, the airbag is inflated to squeeze the sealing ring 33 so that the sealing ring 33 deforms and fits; or it can be a screw threaded to the semi-circular plate 31. Rotating the screw squeezes the sealing ring 33 so that the sealing ring 33 deforms and fits; or other structures known to those skilled in the art.

[0044] As another embodiment of the present invention, the sealing ring 33 is provided with symmetrically arranged retaining grooves 331, and the two semi-circular retaining plates 31 are driven to be respectively engaged with the retaining grooves 331 of the other sealing ring 33.

[0045] Specifically, the first end of the semi-circular arc plate 31 (with Figure 5 For reference, the first end (the upper end) is equipped with a snap-fit ​​connector 312;

[0046] During installation, first apply adhesive (adhesive strip or glue) to one side of the panel frame 1 to be pasted onto the wall. Then, starting from the bottom of the wall, install the first panel frame 1, pasting it onto the wall. Next, hold the second panel frame 1 at an angle and align its semi-circular clamping plate 31 with the two semi-circular clamping plates 31 on the first panel frame 1 to complete the mating installation. At this point, the mating semi-circular clamping plates 31 also have a certain sealing effect, eliminating gaps between the two panel frames 1, reducing the contact of humid air with the adhesive, thereby slowing down the aging of the adhesive. Furthermore, the sealing ring 33 inside the second panel frame 1 will be compressed and deformed, approaching the sealing ring 33 on the first panel frame 1, so that the two sealing rings 33 come into contact to achieve a sealing effect, further isolating the humid air in the room and slowing down the aging time of the adhesive. Moreover, when the two semi-circular clamping plates 31 are clamped onto the semi-circular clamping plates 31 on the other panel frame 1, the two clamping joints 312 on the clamped semi-circular clamping plates 31 will... The clamping plate 331 is attached to the groove 331 on the sealing ring 33, so that the semi-circular clamping plate 31 of the clamp will hook the sealing ring 33. The hooking effect adds an extra layer of fixation, making the connection between the two plate frames 1 tighter. In addition, when the semi-circular clamping plate 31 of the clamp on one of the plate frames 1 is detached by external force, the semi-circular clamping plate 31 hooked on the sealing ring 33 can also hook and pull to prevent it from falling, which plays a double protection role. Then, the plate frame 1 is flipped so that the side covered with adhesive is attached to the wall. After the body is fully fitted and installed, the wall panel frame 1 is laid and installed in sequence. The two sets of symmetrical semi-circular clamping plates 31 can enhance the connection between the panel frame 1 and the panel frame 1. When a single panel frame 1 falls off, it will be pulled by the surrounding panel frame 1 to prevent it from falling off. It can also prevent the aging of the adhesive on a single panel frame 1 from falling off and threatening people in the room. After the two sets of semi-circular clamping plates 31 are clamped, the panel frame 1 can also be held by hand and rotated or slid along the clamping position to make fine adjustments to the installation position.

[0047] As another embodiment of the present invention, a snap-fit ​​thin-walled groove 311 is symmetrically provided on the semi-circular arc plate 31, and the first end of one semi-circular arc plate 31 is driven to snap into the snap-fit ​​thin-walled groove 311 on the other semi-circular arc plate 31.

[0048] Specifically, the first end of the semi-circular arc plate 31 (with Figure 5 For reference, the first end (the upper end) is provided with a snap-fit ​​connector 312, which can snap onto the snap-fit ​​thin-walled groove 311 for locking and fixing;

[0049] During installation, the first panel frame 1 is installed starting from the bottom of the wall. Then, the second panel frame 1 is held at an angle, and its semi-circular clamping plates 31 are aligned with the two semi-circular clamping plates 31 on the first panel frame 1. This allows one set of semi-circular clamping plates 31 to clamp the other set, completing the connection. At this point, the clamping semi-circular clamping plates 31 also provide a certain sealing effect, eliminating gaps between the two panel frames 1, reducing the contact of humid air with the adhesive, and thus slowing down adhesive aging. Furthermore, the sealing rings 33 inside the second panel frame 1 are compressed and deformed, bringing them closer to the sealing rings 33 on the first panel frame 1, so that the two sealing rings 33 come into contact, achieving a sealing effect. This further isolates the room from humid air, slowing down the aging of the adhesive. Moreover, when the two semi-circular clamping plates 31 are clamped onto the semi-circular clamping plates 31 on the other panel frame 1, they are clamped together... The two clips 312 on the semi-circular arc plate 31 of the clamp will engage with the clip groove 331 on the sealing ring 33, so that the semi-circular arc plate 31 of the clamp will hook the sealing ring 33. The hooking effect adds another layer of fixation, making the connection between the two plate frames 1 tighter. When the semi-circular arc plate 31 of the clamp on one of the plate frames 1 is detached by external force, the semi-circular arc plate 31 hooked on the sealing ring 33 can also hook and pull to prevent it from falling, playing a double protection role. The clips 312 on the outer semi-circular arc plate 31 of the clamp will engage with the clip thin-wall groove 311 on the inner semi-circular arc plate 31 for locking and fixing, which can increase the fixing capacity of the two sets of semi-circular arc plates 31 after the clamp. Then, the plate frame 1 is flipped so that the side covered with adhesive is attached to the wall to complete the installation. Then, the wall plate frame 1 is laid and installed in sequence.

[0050] As a further embodiment of the present invention, the semi-circular arc plate 31 is symmetrically provided with snap-fit ​​thin-walled grooves 311. When the two plate frames 1 are driven to be parallel to each other, the semi-circular arc plate 31 operates along the following three stations:

[0051] First station: The semi-circular arc plate 31 is driven to bend, so as to drive the other semi-circular arc plate 31 to move closer to the center of the two semi-circular arc plates 31.

[0052] Second station: One of the semi-circular arc plates 31 on one of the plate frames 1 is driven to slide along the outer wall of one of the semi-circular arc plates 31 on the other plate frame 1 into the inner wall of the semi-circular arc plate 31.

[0053] Third station: Two semi-circular arc clamping plates 31 on another plate frame 1.

[0054] Specifically, the snap-fit ​​thin-walled groove 311 can reduce the wall thickness of the semi-circular arc plate 31, so that the semi-circular arc plate 31 bends along the snap-fit ​​thin-walled groove 311 when subjected to external force.

[0055] During installation, the first panel frame 1 is installed starting from the bottom of the wall. Then, the second panel frame 1 is held at an angle, and its semi-circular clamping plates 31 are aligned with the two semi-circular clamping plates 31 on the first panel frame 1. This allows one set of semi-circular clamping plates 31 to clamp the other set, completing the connection. At this point, the clamping semi-circular clamping plates 31 also provide a certain sealing effect, eliminating gaps between the two panel frames 1, reducing the contact of humid air with the adhesive, and thus slowing down adhesive aging. Furthermore, the sealing rings 33 inside the second panel frame 1 are compressed and deformed, bringing them closer to the sealing rings 33 on the first panel frame 1, so that the two sealing rings 33 come into contact, achieving a sealing effect. This further isolates the room from humid air, slowing down the aging of the adhesive. Moreover, when the two semi-circular clamping plates 31 are clamped onto the semi-circular clamping plates 31 on the other panel frame 1, they are clamped together... The two clips 312 on the semi-circular arc plate 31 of the clamp will engage with the clip groove 331 on the sealing ring 33, so that the semi-circular arc plate 31 of the clamp will hook the sealing ring 33. The hooking effect adds another layer of fixation, making the connection between the two plate frames 1 tighter. When the semi-circular arc plate 31 of the clamp on one of the plate frames 1 is detached by external force, the semi-circular arc plate 31 hooked on the sealing ring 33 can also hook and pull to prevent it from falling, playing a double protection role. The clips 312 on the outer semi-circular arc plate 31 of the clamp will engage with the clip thin-wall groove 311 on the inner semi-circular arc plate 31 for locking and fixing, which can increase the fixing capacity of the two sets of semi-circular arc plates 31 after the clamp. Then, the plate frame 1 is flipped so that the side covered with adhesive is attached to the wall to complete the installation. Then, the wall plate frame 1 is laid and installed in sequence.

[0056] When one of the panels on the wall needs to be replaced, a screwdriver or similar tool can be used to insert and knock the panel out along the joint. Then, the new panel frame 1 can be taken out and aligned parallel to the other panel frames 1. At this time, the semi-circular clamping plate 31 will move along the following three positions:

[0057] First station: When one of the semi-circular arc plates 31 on a plate frame 1 is bent, the other semi-circular arc plate 31 will move closer together along the center of the two semi-circular arc plates 31.

[0058] Second work station: At the first end of the new plate frame 1 (the new plate frame 1 is one of the plate frames 1) (with Figure 5 For reference, the first end is the right end and the second end is the left end. The semi-circular arc plate 31 first slides close to the outer wall of the second end of the semi-circular arc plate 31 on the old plate frame 1 (the old plate frame 1 is another plate frame 1), and finally slides into the space between the two semi-circular arc plates 31 on the old plate frame 1.

[0059] Third station: The new plate frame 1 continues to move parallel to the old plate frame 1, so that the semi-circular arc plate 31 at the first end of the new plate frame 1 pushes against the inner wall of the semi-circular arc plate 31 at the first end of the old plate frame 1, causing deformation. At this time, the semi-circular arc plates 31 at the second end of both the new and old plate frames 1 will move closer to the center of the two semi-circular arc plates 31. With the parallel movement, the semi-circular arc plate 31 at the second end of the old plate frame 1 will completely fit the sealing ring 33 on the old plate frame 1 and be fixed in place. As the new plate frame 1 moves, the semi-circular arc plate 31 at the second end of the new plate frame 1 will also fit against the sealing ring 33 on the new plate frame 1 and continue to move with the sealing ring 33 to between the two semi-circular arc plates 31 on the old plate frame 1. At this time, the new plate frame 1 is released so that the two semi-circular arc plates 31 on the old plate frame 1 spring back to clamp the two semi-circular arc plates 31 on the new plate frame 1. This allows for easy replacement of damaged plate frames 1 on the wall, and facilitates installation without distinguishing between the front and back of the plate.

[0060] As the preferred embodiment of the present invention, a flexible connecting part 32 is slidably connected inside the two semi-circular arc plates 31, and the two ends of the flexible connecting part 32 are respectively fixedly connected to the first ends of the two semi-circular arc plates 31.

[0061] Specifically, a groove 313 is provided between the two semi-circular arc plates 31, and a flexible connecting part 32 is slidably connected within the groove 313. The two ends of the flexible connecting part 32 are respectively fixedly connected to the first ends of the two semi-circular arc plates 31 (with...). Figure 5 For reference, the first end is the upper end), the semi-circular plate 31 is made of elastic material and has an extension effect;

[0062] During installation, the first panel frame 1 is installed starting from the bottom of the wall. Then, the second panel frame 1 is held at an angle, and its semi-circular clamping plates 31 are aligned with the two semi-circular clamping plates 31 on the first panel frame 1. This allows one set of semi-circular clamping plates 31 to clamp the other set, completing the connection. At this point, the clamping semi-circular clamping plates 31 also provide a certain sealing effect, eliminating gaps between the two panel frames 1, reducing the contact of humid air with the adhesive, and thus slowing down adhesive aging. Furthermore, the sealing rings 33 inside the second panel frame 1 are compressed and deformed, bringing them closer to the sealing rings 33 on the first panel frame 1, so that the two sealing rings 33 come into contact, achieving a sealing effect. This further isolates the room from humid air, slowing down the aging of the adhesive. Moreover, when the two semi-circular clamping plates 31 are clamped onto the semi-circular clamping plates 31 on the other panel frame 1, they are clamped together... The two clips 312 on the semi-circular arc plate 31 of the clamp will engage with the clip groove 331 on the sealing ring 33, so that the semi-circular arc plate 31 of the clamp will hook the sealing ring 33. The hooking effect adds another layer of fixation, making the connection between the two plate frames 1 tighter. When the semi-circular arc plate 31 of the clamp on one of the plate frames 1 is detached by external force, the semi-circular arc plate 31 hooked on the sealing ring 33 can also hook and pull to prevent it from falling, playing a double protection role. The clips 312 on the outer semi-circular arc plate 31 of the clamp will engage with the clip thin-wall groove 311 on the inner semi-circular arc plate 31 for locking and fixing, which can increase the fixing capacity of the two sets of semi-circular arc plates 31 after the clamp. Then, the plate frame 1 is flipped so that the side covered with adhesive is attached to the wall to complete the installation. Then, the wall plate frame 1 is laid and installed in sequence.

[0063] When one of the panels on the wall needs to be replaced, a screwdriver or similar tool can be used to insert and knock the panel out along the joint. Then, the new panel frame 1 can be taken out and aligned parallel to the other panel frames 1. At this time, the semi-circular clamping plate 31 will move along the following three positions:

[0064] First station: When one of the semi-circular arc plates 31 on a plate frame 1 is bent, the semi-circular arc plate 31 will bend and extend with the snap-fit ​​thin-walled groove 311 as the base point. The other part of the semi-circular arc plate 31 is thicker and has poor extension ability, so the snap-fit ​​thin-walled groove 311 extends a long distance when bending. At this time, the flexible connection part 32 will bend together with the other semi-circular arc plate 31 on the plate frame 1. At this time, the other one will move closer to the center of the two semi-circular arc plates 31.

[0065] Second work station: At the first end of the new plate frame 1 (the new plate frame 1 is one of the plate frames 1) (with Figure 5For reference, the first end is the right end and the second end is the left end. The semi-circular arc plate 31 first slides close to the outer wall of the second end of the semi-circular arc plate 31 on the old plate frame 1 (the old plate frame 1 is another plate frame 1), and finally slides into the space between the two semi-circular arc plates 31 on the old plate frame 1.

[0066] Third station: The new plate frame 1 continues to move parallel to the old plate frame 1, so that the semi-circular arc plate 31 at the first end of the new plate frame 1 pushes against the inner wall of the semi-circular arc plate 31 at the first end of the old plate frame 1, causing deformation. At this time, the semi-circular arc plates 31 at the second end of both the new and old plate frames 1 will move closer to the center of the two semi-circular arc plates 31. With the parallel movement, the semi-circular arc plate 31 at the second end of the old plate frame 1 will completely fit the sealing ring 33 on the old plate frame 1 and be fixed in place. As the new plate frame 1 moves, the semi-circular arc plate 31 at the second end of the new plate frame 1 will also fit against the sealing ring 33 on the new plate frame 1 and continue to move with the sealing ring 33 to between the two semi-circular arc plates 31 on the old plate frame 1. At this time, the new plate frame 1 is released so that the two semi-circular arc plates 31 on the old plate frame 1 spring back to clamp the two semi-circular arc plates 31 on the new plate frame 1. This allows for easy replacement of damaged plate frames 1 on the wall, and facilitates installation without distinguishing between the front and back of the plate.

[0067] As the preferred embodiment provided by the present invention, a hollow layer 11 is provided inside the plate frame 1, and a sealing ring 33 is sleeved on the side wall of the plate frame 1. The sealing ring 33 is fixedly connected with the hollow layer 11. A concave-convex mating part 341 is provided on the sealing ring 33, and a venting part 34 is provided on the concave-convex mating part 341. The sealing ring 33 is deformed by being driven and squeezed, so as to drive the concave-convex mating part 341 to protrude and fit against the concave-convex mating part 341 on another sealing ring 33, so that the two sealing rings 33 are connected.

[0068] Specifically, a hollow layer 11 is provided inside the plate frame 1, which can play a role in sound insulation. The sealing ring 33 has a concave-convex mating part 341. The sealing ring 33 is made of rubber and has good elasticity. A ventilation part 34 is provided on the concave-convex mating part 341. A magnetic mating ring 343 is provided along the ventilation part 34 on the concave-convex mating part 341. The ventilation part 34 and the hollow layer 11 are fixedly connected. A serrated folding part 342 is provided on the ventilation part 34, which is adjacent to the hollow layer 11. A fixing groove 332 is symmetrically provided on the sealing ring 33. A fixing buckle 333 is provided on the plate frame 1. When the sealing ring 33 is sleeved on the plate frame 1, the fixing buckle 333 is engaged with the fixing groove 332 to fix the sealing ring 33.

[0069] During installation, the first panel frame 1 is installed starting from the bottom of the wall. Then, the second panel frame 1 is held at an angle, and its semi-circular clamping plate 31 is aligned with the two semi-circular clamping plates 31 on the first panel frame 1. This allows one set of semi-circular clamping plates 31 to clamp the other set, completing the mating installation. At this point, the mating semi-circular clamping plates 31 also provide a certain sealing effect, eliminating gaps between the two panel frames 1, reducing the contact of moisture with the adhesive, and thus slowing down adhesive aging. Furthermore, the sealing ring 33 inside the second panel frame 1 will be clamped due to the semi-circular clamping effect. The arc-shaped plate 31 is compressed and deformed to approach the sealing ring 33 on the first plate frame 1, so that the two sealing rings 33 come into contact to achieve a sealing effect, further isolating the room from humid air and slowing down the aging time of the adhesive. At the same time as the sealing ring 33 is compressed, the recessed convex-concave mating part 341 is also compressed into a convex state, and the folded serrated part 342 is pulled into a vertical state. The convex convex-concave mating part 341 extends into the recessed convex-concave mating part 341 of another uncompressed sealing ring 33. At this time, the two convex-concave mating parts 341 The magnetic attraction rings 343 on the upper part of the plate frame 1 are attracted to each other, so that the hollow layers 11 on the plate frame 1 are interconnected, forming a continuous hollow layer 11 on one whole surface to enhance the sound insulation effect. Moreover, when the two semi-circular arc plates 31 are clamped onto the semi-circular arc plates 31 on the other plate frame 1, the two clamping joints 312 on the clamped semi-circular arc plates 31 will clamp onto the clamping grooves 331 on the sealing ring 33, so that the clamped semi-circular arc plates 31 will hook the sealing ring 33. The hooking effect adds another layer of fixation, making the connection between the two plate frames 1 tighter, and in one of the plate frames When the semi-circular arc plate 31 of the clamp on frame 1 is detached by external force, the semi-circular arc plate 31 hooked on the sealing ring 33 can also be hooked and pulled to prevent it from falling, playing a double protection role. The clamping joint 312 on the outer semi-circular arc plate 31 of the clamp will be clamped on the clamping thin-wall groove 311 on the inner semi-circular arc plate 31 for locking and fixing, which can increase the fixing capacity of the two sets of semi-circular arc plates 31 after the clamp. Then, the plate frame 1 is flipped so that the side covered with adhesive is attached to the wall to complete the installation. Then, the wall plate frame 1 is laid and installed in sequence.

[0070] When one of the panels on the wall needs to be replaced, a screwdriver or similar tool can be used to insert and knock the panel out along the joint. Then, the new panel frame 1 can be taken out and aligned parallel to the other panel frames 1. At this time, the semi-circular clamping plate 31 will move along the following three positions:

[0071] First station: When one of the semi-circular arc plates 31 on a plate frame 1 is bent, the semi-circular arc plate 31 will bend and extend with the snap-fit ​​thin-walled groove 311 as the base point. The other part of the semi-circular arc plate 31 is thicker and has poor extension ability, so the snap-fit ​​thin-walled groove 311 extends a long distance when bending. At this time, the flexible connection part 32 will bend together with the other semi-circular arc plate 31 on the plate frame 1. At this time, the other one will move closer to the center of the two semi-circular arc plates 31.

[0072] Second work station: At the first end of the new plate frame 1 (the new plate frame 1 is one of the plate frames 1) (with Figure 5 For reference, the first end is the right end and the second end is the left end. The semi-circular arc plate 31 first slides close to the outer wall of the second end of the semi-circular arc plate 31 on the old plate frame 1 (the old plate frame 1 is another plate frame 1), and finally slides into the space between the two semi-circular arc plates 31 on the old plate frame 1.

[0073] Third station: The new plate frame 1 continues to move parallel to the old plate frame 1, so that the semi-circular arc plate 31 at the first end of the new plate frame 1 pushes against the inner wall of the semi-circular arc plate 31 at the first end of the old plate frame 1, causing deformation. At this time, the semi-circular arc plates 31 at the second end of both the new and old plate frames 1 will move closer to the center of the two semi-circular arc plates 31. With the parallel movement, the semi-circular arc plate 31 at the second end of the old plate frame 1 will completely fit the sealing ring 33 on the old plate frame 1 and be fixed in place. As the new plate frame 1 moves, the semi-circular arc plate 31 at the second end of the new plate frame 1 will also fit against the sealing ring 33 on the new plate frame 1 and continue to move with the sealing ring 33 to between the two semi-circular arc plates 31 on the old plate frame 1. At this time, the new plate frame 1 is released so that the two semi-circular arc plates 31 on the old plate frame 1 spring back to clamp the two semi-circular arc plates 31 on the new plate frame 1. This allows for easy replacement of damaged plate frames 1 on the wall, and facilitates installation without distinguishing between the front and back of the plate.

[0074] As the preferred embodiment provided by the present invention, a sound insulation component 2 is provided on the plate frame 1. The sound insulation component 2 includes a sound-absorbing cotton board 21 and a nylon sound insulation board 22 respectively disposed on the plate frame 1.

[0075] Specifically, the frame 1 has symmetrically arranged storage slots 10. The sound-absorbing cotton board 21 and the nylon sound insulation board 22 are respectively placed in the two storage slots 10. The sound-absorbing cotton board 21 can absorb sound waves and reduce sound, while the nylon sound insulation board 22 has poor sound transmission ability and can play a good role in isolating the volume.

[0076] During installation, the first panel frame 1 is installed starting from the bottom of the wall. Then, the second panel frame 1 is held at an angle, and its semi-circular clamping plate 31 is aligned with the two semi-circular clamping plates 31 on the first panel frame 1. This allows one set of semi-circular clamping plates 31 to clamp the other set, completing the mating installation. At this point, the mating semi-circular clamping plates 31 also provide a certain sealing effect, eliminating gaps between the two panel frames 1, reducing the contact of moisture with the adhesive, and thus slowing down adhesive aging. Furthermore, the sealing ring 33 inside the second panel frame 1 will be clamped due to the semi-circular clamping effect. The arc-shaped plate 31 is compressed and deformed to approach the sealing ring 33 on the first plate frame 1, so that the two sealing rings 33 come into contact to achieve a sealing effect, further isolating the room from humid air and slowing down the aging time of the adhesive. At the same time as the sealing ring 33 is compressed, the recessed convex-concave mating part 341 is also compressed into a convex state, and the folded serrated part 342 is pulled into a vertical state. The convex convex-concave mating part 341 extends into the recessed convex-concave mating part 341 of another uncompressed sealing ring 33. At this time, the two convex-concave mating parts 341 The magnetic attraction rings 343 on the upper part of the plate frame 1 are attracted to each other, so that the hollow layers 11 on the plate frame 1 are interconnected, forming a continuous hollow layer 11 on one whole surface to enhance the sound insulation effect. Moreover, when the two semi-circular arc plates 31 are clamped onto the semi-circular arc plates 31 on the other plate frame 1, the two clamping joints 312 on the clamped semi-circular arc plates 31 will clamp onto the clamping grooves 331 on the sealing ring 33, so that the clamped semi-circular arc plates 31 will hook the sealing ring 33. The hooking effect adds another layer of fixation, making the connection between the two plate frames 1 tighter, and in one of the plate frames When the semi-circular arc plate 31 of the clamp on frame 1 is detached by external force, the semi-circular arc plate 31 hooked on the sealing ring 33 can also be hooked and pulled to prevent it from falling, playing a double protection role. The clamping joint 312 on the outer semi-circular arc plate 31 of the clamp will be clamped on the clamping thin-wall groove 311 on the inner semi-circular arc plate 31 for locking and fixing, which can increase the fixing capacity of the two sets of semi-circular arc plates 31 after the clamp. Then, the plate frame 1 is flipped so that the side covered with adhesive is attached to the wall to complete the installation. Then, the wall plate frame 1 is laid and installed in sequence.

[0077] When one of the panels on the wall needs to be replaced, a screwdriver or similar tool can be used to insert and knock the panel out along the joint. Then, the new panel frame 1 can be taken out and aligned parallel to the other panel frames 1. At this time, the semi-circular clamping plate 31 will move along the following three positions:

[0078] First station: When one of the semi-circular arc plates 31 on a plate frame 1 is bent, the semi-circular arc plate 31 will bend and extend with the snap-fit ​​thin-walled groove 311 as the base point. The other part of the semi-circular arc plate 31 is thicker and has poor extension ability, so the snap-fit ​​thin-walled groove 311 extends a long distance when bending. At this time, the flexible connection part 32 will bend together with the other semi-circular arc plate 31 on the plate frame 1. At this time, the other one will move closer to the center of the two semi-circular arc plates 31.

[0079] Second work station: At the first end of the new plate frame 1 (the new plate frame 1 is one of the plate frames 1) (with Figure 5 For reference, the first end is the right end and the second end is the left end. The semi-circular arc plate 31 first slides close to the outer wall of the second end of the semi-circular arc plate 31 on the old plate frame 1 (the old plate frame 1 is another plate frame 1), and finally slides into the space between the two semi-circular arc plates 31 on the old plate frame 1.

[0080] Third station: The new plate frame 1 continues to move parallel to the old plate frame 1, so that the semi-circular arc plate 31 at the first end of the new plate frame 1 pushes against the inner wall of the semi-circular arc plate 31 at the first end of the old plate frame 1, causing deformation. At this time, the semi-circular arc plates 31 at the second end of both the new and old plate frames 1 will move closer to the center of the two semi-circular arc plates 31. With the parallel movement, the semi-circular arc plate 31 at the second end of the old plate frame 1 will completely fit the sealing ring 33 on the old plate frame 1 and be fixed in place. As the new plate frame 1 moves, the semi-circular arc plate 31 at the second end of the new plate frame 1 will also fit against the sealing ring 33 on the new plate frame 1 and continue to move with the sealing ring 33 to between the two semi-circular arc plates 31 on the old plate frame 1. At this time, the new plate frame 1 is released so that the two semi-circular arc plates 31 on the old plate frame 1 spring back to clamp the two semi-circular arc plates 31 on the new plate frame 1. This allows for easy replacement of damaged plate frames 1 on the wall, and facilitates installation without distinguishing between the front and back of the plate.
