Description

Technical Field

[0001] This utility model relates to the field of sound insulation board technology, and more specifically, to a layered sound barrier structure. Background Technology

[0002] Layered sound barrier panels are a highly efficient noise control facility. Their structural design and material selection are aimed at minimizing the propagation and impact of noise. The structure typically consists of multiple layers, including a metal front panel, metal side panels, a metal back panel, and sound-absorbing cotton filling the middle. These panels are tightly connected together by specific fasteners, such as fixed corner brackets and stacking nodes, to form a unified sound insulation structure.

[0003] Traditional layered sound barrier structures have the following shortcomings: Traditional layered sound barrier structures, including sound insulation panels, are widely used as an important component of building exterior noise protection to create quiet interior spaces. However, these sound insulation panels are often made of robust and durable materials and designed with a heavy structure to achieve optimal sound insulation. While this design effectively improves sound insulation performance, it also introduces weight issues. During installation, due to their weight, construction workers usually have to use bolts to firmly fix them to the wall or frame. This step is not only complex but also time-consuming and labor-intensive, requiring relatively high technical skills from the installers. Similarly, when it is necessary to remove or replace the sound insulation panels, the disassembly process of the bolted connections is particularly cumbersome. Slight carelessness can damage the sound insulation panels or the wall, further increasing maintenance costs; therefore, improvements are needed. Utility Model Content

[0004] To overcome the shortcomings of the existing technology, this utility model provides a stacked sound barrier structure, which has the advantage of being easy to install and disassemble.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a layered sound barrier structure, comprising a base, a bottom plate movably mounted on top of the base, a front plate fixedly mounted on top of the bottom plate, side plates fixedly mounted on both sides of the front plate, a top plate fixedly mounted on top of the side plates, a rear plate fixedly mounted on the rear side of the side plates, a platform fixedly mounted on top of the base and located behind the rear plate, a column fixedly mounted on top of the platform, a top cover fixedly mounted on top of the column, sound-absorbing cotton fixedly mounted between the inner sides of the front plate and the inner sides of the rear plate, an insert plate extending into the interior of the column fixedly mounted on the rear side of the rear plate, a slot opened inside the column, movable grooves opened on both sides of the insert plate, and inclined blocks extending into the slots movably mounted inside the movable grooves.

[0006] As a preferred embodiment of this utility model, a rectangular groove is provided inside the base, a rectangular plate is movably installed inside the rectangular groove, a horizontal plate extending to the outside of the base is fixedly installed on the outside of the rectangular plate, a baffle is fixedly installed on the outside of the horizontal plate, and a buffer spring is uniformly and elastically installed between the inside of the rectangular groove and the inside of the rectangular plate.

[0007] As a preferred technical solution of this utility model, limit grooves are provided on both sides of the movable groove, and limit blocks located inside the limit grooves are fixedly installed on both sides of the bottom of the inclined block.

[0008] As a preferred embodiment of this utility model, a connecting plate extending to the outside of the column is movably installed inside the slot. The connecting plate is located outside the inclined block, and a push plate is fixedly installed on the outside of the connecting plate.

[0009] As a preferred embodiment of this utility model, the slot has sliding grooves on both sides, and the bottom sides of the connecting plate are fixedly installed with sliders located inside the sliding grooves.

[0010] As a preferred embodiment of this utility model, a return spring is elastically installed on the inner side of the slide groove, and the return spring is located on the inner side of the slider.

[0011] As a preferred embodiment of this utility model, a telescopic spring is elastically installed on the inner side of the movable groove, and the telescopic spring is located at the bottom of the inclined block.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] 1. This utility model fixes the insert plate by inserting it into the interior of the column and releasing the elastic potential energy of the telescopic spring to push the inclined block into the interior of the slot. Pressing the push plate causes the inclined block to retract into the interior of the movable slot, thereby removing the insert plate. Compared with the traditional stacked sound barrier structure, this stacked sound barrier structure completes the installation of the rear panel conveniently through the insert plate and the column. The push plate detaches the insert plate from the column, making it easy to use.

[0014] 2. This utility model uses a baffle to cause the horizontal plate to retract into the rectangular groove, which causes the buffer spring to deform, thus buffering the baffle. Compared with the traditional stacked sound barrier structure, this stacked sound barrier structure has a baffle on the outside of the base, which buffers the contact between the vehicle and the base and protects the base.

[0021] 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.

[0022] like Figures 1 to 5 As shown, this utility model provides a stacked sound barrier structure, including a base 1, a base plate 2 movably installed on the top of the base 1, a front plate 3 fixedly installed on the top of the base plate 2, side plates 4 fixedly installed on both sides of the front plate 3, a top plate 5 fixedly installed on the top of the side plates 4, a rear plate 9 fixedly installed on the rear side of the side plates 4, a platform 6 located behind the rear plate 9 fixedly installed on the top of the base 1, a column 7 fixedly installed on the top of the platform 6, a top cover 8 fixedly installed on the top of the column 7, sound-absorbing cotton 10 fixedly installed between the inner side of the front plate 3 and the inner side of the rear plate 9, an insert plate 11 extending into the interior of the column 7 fixedly installed on the rear side of the rear plate 9, a slot 12 is opened inside the column 7, movable grooves 13 are opened on both sides of the insert plate 11, and inclined blocks 14 extending into the interior of the slot 12 are movably installed inside the movable grooves 13.

[0023] When the rear plate 9 needs to be installed, insert the insert plate 11 into the interior of the column 7, causing the inclined block 14 to be compressed and retracted into the interior of the movable groove 13. This causes the inclined block 14 to compress the telescopic spring 15, deforming the telescopic spring 15. When the insert plate 11 is inserted to the bottom, the telescopic spring 15 releases its elastic potential energy to push the inclined block 14 into the interior of the slot 12, thereby fixing the insert plate 11. When the rear plate 9 needs to be disassembled, press the push plate 20, causing the push plate 20 to drive the connecting plate 19 to move inward and compress the inclined block 14, causing the inclined block 14 to retract into the interior of the movable groove 13, thereby removing the insert plate 11.

[0024] By inserting the insert plate 11 into the interior of the column 7, the telescopic spring 15 releases its elastic potential energy to push the inclined block 14 into the interior of the slot 12, thereby fixing the insert plate 11. Pressing the push plate 20 causes the inclined block 14 to retract into the interior of the movable slot 13, thereby removing the insert plate 11. Compared with the traditional stacked sound barrier structure, this stacked sound barrier structure conveniently completes the installation of the rear panel 9 through the insert plate 11 and the column 7. The push plate 20 allows the insert plate 11 to detach from the column 7, making it easy to use.

[0025] The base 1 has a rectangular groove 23 inside, a rectangular plate 24 is movably installed inside the rectangular groove 23, a horizontal plate 25 extending to the outside of the base 1 is fixedly installed on the outside of the rectangular plate 24, a baffle 26 is fixedly installed on the outside of the horizontal plate 25, and a buffer spring 27 is uniformly and elastically installed between the inside of the rectangular groove 23 and the inside of the rectangular plate 24.

[0026] When the vehicle comes into contact with the baffle 26, the baffle 26 is subjected to a squeezing force and moves inward, causing the horizontal plate 25 to retract into the interior of the rectangular groove 23. This causes the rectangular plate 24 to squeeze the buffer spring 27, causing the buffer spring 27 to deform, thus buffering the baffle 26. The elastic potential energy released by the spring 27 pushes the rectangular plate 24 to move outward, thereby causing the baffle 26 to return to its original position.

[0027] The baffle 26 causes the horizontal plate 25 to retract into the rectangular groove 23, causing the buffer spring 27 to deform, thus buffering the baffle 26. Compared with the traditional stacked sound barrier structure, this stacked sound barrier structure provides a buffer between the vehicle and the base 1 by setting the baffle 26 on the outside of the base 1, thus protecting the base 1.

[0028] Among them, the movable groove 13 has limit grooves 16 on both sides, and the bottom sides of the inclined block 14 are fixedly installed with limit blocks 17 located inside the limit grooves 16.

[0029] The inclined block 14 retracts into the interior of the movable groove 13, causing the limiting block 17 to move inside the limiting groove 16, thereby limiting the inclined block 14.

[0030] The slot 12 has a connecting plate 19 that extends to the outside of the column 7. The connecting plate 19 is located outside the inclined block 14, and a push plate 20 is fixedly installed on the outside of the connecting plate 19.

[0031] Push the push plate 20, causing the push plate 20 to move the connecting plate 19 inside the slot 12, thereby squeezing the inclined block 14 and causing the inclined block 14 to retract into the interior of the movable slot 13.

[0032] The slot 12 has grooves 18 on both sides, and the bottom sides of the connecting plate 19 are fixedly installed with sliders 21 located inside the grooves 18.

[0033] The movement of the connecting plate 19 inside the slot 12 causes the slider 21 to move inside the slide groove 18, thereby limiting the movement of the connecting plate 19.

[0034] A return spring 22 is elastically installed on the inner side of the slide groove 18, and the return spring 22 is located on the inner side of the slider 21.

[0035] The slider 21 moves inward inside the groove 18, squeezing the return spring 22 and causing the return spring 22 to deform, thereby pushing the slider 21 back to its original position.

[0036] The inner side of the movable groove 13 is elastically fitted with a telescopic spring 15, which is located at the bottom of the inclined block 14.

[0037] The inclined block 14 moves inward inside the movable groove 13, squeezing the telescopic spring 15, causing the telescopic spring 15 to deform. The telescopic spring 15 releases its elastic potential energy, pushing the inclined block 14 outward.

[0038] Working principle and usage process of this utility model:

[0039] When the rear plate 9 needs to be installed, insert the insert plate 11 into the interior of the column 7, causing the inclined block 14 to be compressed and retracted into the interior of the movable groove 13. This causes the inclined block 14 to compress the telescopic spring 15, deforming the telescopic spring 15. When the insert plate 11 is inserted to the bottom, the telescopic spring 15 releases its elastic potential energy to push the inclined block 14 into the interior of the slot 12, thereby fixing the insert plate 11. When the rear plate 9 needs to be disassembled, press the push plate 20, causing the push plate 20 to drive the connecting plate 19 to move inward and compress the inclined block 14, causing the inclined block 14 to retract into the interior of the movable groove 13, thereby removing the insert plate 11.

[0040] When the vehicle comes into contact with the baffle 26, the baffle 26 is subjected to a squeezing force and moves inward, causing the horizontal plate 25 to retract into the interior of the rectangular groove 23. This causes the rectangular plate 24 to squeeze the buffer spring 27, causing the buffer spring 27 to deform, thus buffering the baffle 26. The buffer spring 27 releases its elastic potential energy, pushing the rectangular plate 24 to move outward, thereby causing the baffle 26 to return to its original position.
