Description

Technical Field

[0001] This utility model relates to the field of noise reduction technology, specifically a sound barrier that can be quickly assembled. Background Technology

[0002] Noise barriers are primarily used for sound insulation and noise reduction along highways, expressways, elevated roads, and other noise sources. They refer to wall-like structures erected alongside railways and highways to mitigate the impact of traffic noise on nearby residents. Also known as sound barriers, these barriers are structures inserted between the sound source and the receiver, significantly attenuating sound wave propagation and thus reducing noise impact within a certain area where the receiver is located.

[0003] Chinese utility model patent CN217839770U discloses a high-efficiency noise-reducing combined sound-absorbing and insulating barrier. This invention solves the problem that existing sound barriers lack a quick-connect structure, requiring multiple workers for support during installation, which is time-consuming, labor-intensive, and inefficient. The high-efficiency noise-reducing combined sound-absorbing and insulating barrier includes several mounting frames. Each mounting frame contains a combined sound-insulating structure, and each frame has a mounting section at its bottom. The mounting section includes a support plate and two vertical plates symmetrically arranged at the bottom of the support plate. The combined sound-insulating structure includes a sound-insulating plate detachably connected inside the mounting frame and two sound-absorbing plates symmetrically arranged on one side of the sound-insulating plate. This utility model has a reasonable structure, facilitates quick assembly and disassembly, improves noise reduction and sound insulation capabilities, saves time and labor, and increases installation efficiency.

[0004] In the existing technical solutions mentioned above, the load-bearing plate is connected to the installation position through vertical plates. This connection method may have insufficient load-bearing capacity when facing large external forces (such as strong winds, ground construction, and other extreme situations). When the external force exceeds the design load-bearing range, it will lead to structural damage. Therefore, it is urgent to design a sound barrier that can be quickly assembled to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a sound barrier that can be quickly assembled, in order to solve the problem in the above-mentioned background technology where the load-bearing plate is connected to the installation position by a vertical plate. This connection method may have insufficient load-bearing capacity when facing large external forces (such as strong winds, ground construction, and other extreme situations). When the external force exceeds the design load-bearing range, it will lead to structural damage.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a quickly assembled sound barrier, comprising: a mounting frame, a sound insulation board clamped on the side surface of the mounting frame, a support column provided at the bottom of the mounting frame, a base plate fixedly connected to the bottom of the support column, a guide groove formed on the side surface of the mounting frame, a clamping plate movably connected inside the mounting frame, a clamping block movably connected inside the clamping plate, a first limiting plate fixedly connected to the outer surface of the clamping plate, a first spring column fixedly connected to the side of the first limiting plate away from the clamping plate, a second spring column fixedly connected inside the support column, a second limiting plate fixedly connected to the upper surface of the second spring column, and a connecting column movably connected to the upper surface of the second limiting plate.

[0007] Preferably, the bottom of the base plate is fixed with a base, and the outer surface of the base is provided with positioning holes.

[0008] Preferably, the bottom of the base is provided with a storage groove, and an external extension plate is movably connected to the inside of the base.

[0009] Preferably, a fixing ring is fixedly connected to the side surface of the outer expansion plate, and a positioning ring is fixedly connected inside the fixing ring.

[0010] Preferably, the positioning ring is rotatably connected to a rotating rod inside, and the positioning ring is in two sets sleeved at both ends of the rotating rod.

[0011] Preferably, an anti-slip plate is fixedly connected to the outer surface of the outer extension plate, and the anti-slip plate is wavy.

[0012] Preferably, the clamping blocks are fixedly connected in four groups to both sides of the sound insulation board, and the clamping blocks are trapezoidal.

[0013] Preferably, the connecting column is fixedly connected to the bottom center of the mounting frame, and the connecting column is movably connected between the mounting frame and the support column.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. By setting the first spring post and the clamping block, the clamping plate can provide a uniform force to the sound insulation board when clamping the clamping block, so that the force on each contact point is balanced. The uniform force can better withstand external forces and improve the overall load-bearing capacity of the barrier. At the same time, the first spring post can adapt to vibration changes through compression, offset the influence of the environment, and keep the connection tight at all times.

[0016] 2. The base and the outer extension plate make the sound insulation panel more effective in resisting the tendency to overturn when subjected to strong winds. At the same time, the unfolding of the outer extension plate can lower the center of gravity of the sound insulation panel. The lower the center of gravity, the better the stability of the mounting frame, which can effectively reduce the possibility of shaking and tilting. Attached Figure Description

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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.

[0025] Please see Figure 1-6This utility model provides an embodiment of a quickly assembled sound barrier, comprising: a mounting frame 1, a sound insulation plate 2 clamped on the side surface of the mounting frame 1, a support column 3 provided at the bottom of the mounting frame 1, a base plate 4 fixedly connected to the bottom of the support column 3, a guide groove 10 provided on the side surface of the mounting frame 1, a clamping plate 6 movably connected inside the mounting frame 1, a clamping block 7 movably connected inside the clamping plate 6, a first limiting plate 8 fixedly connected to the outer surface of the clamping plate 6, a first spring column 9 fixedly connected to the side of the first limiting plate 8 away from the clamping plate 6, a second spring column 20 fixedly connected inside the support column 3, a second limiting plate 19 fixedly connected to the upper surface of the second spring column 20, and a connecting column 18 movably connected to the upper surface of the second limiting plate 19.

[0026] Specifically, by setting the guide groove 10, the sound insulation plate 2 is inserted into the side of the mounting bracket 1 from top to bottom through the guide groove 10, which can effectively realize the connection between multiple sets of mounting brackets 1 and sound insulation plates 2.

[0027] Please see Figure 1-6 The bottom of the base plate 4 is fixed with a base 5, and the outer surface of the base 5 is provided with positioning holes 11.

[0028] Specifically, by setting the positioning hole 11, when encountering strong winds, nails can be driven through the positioning hole 11 to fix the mounting bracket 1, thereby ensuring the stability of the mounting bracket 1.

[0029] Please see Figure 1-6 The bottom of the base 5 has a storage slot 12, and the interior of the base 5 is movably connected to an extension plate 16.

[0030] Specifically, by setting up the storage slot 12, when the outer extension plate 16 is not in use, the outer extension plate 16 can be flipped and folded into the storage slot 12, which makes it easier for the mounting frame 1 to be disassembled and transported, reducing space occupation.

[0031] Please see Figure 1-6 A fixing ring 13 is fixedly connected to the side surface of the outer expansion plate 16, and a positioning ring 14 is fixedly connected inside the fixing ring 13.

[0032] Specifically, the positioning ring 14 stabilizes the rotating rod 15, ensuring that the rotating rod 15 does not loosen when the outer extension plate 16 is rotated, thus effectively improving the practicality of the device.

[0033] Please see Figure 1-6 The positioning ring 14 is rotatably connected to the rotating rod 15 inside, and the positioning ring 14 is sleeved in two sets at both ends of the rotating rod 15.

[0034] Specifically, by setting the rotating rod 15, the outer extension plate 16 can be rotated by means of the rotating rod 15, so that the outer extension plate 16 can be stored or extended.

[0035] Please see Figure 1-6 An anti-slip plate 17 is fixedly connected to the outer surface of the outer extension plate 16. The anti-slip plate 17 is wavy.

[0036] Specifically, by setting the anti-slip plate 17, the friction of the mounting bracket 1 can be effectively increased when it is supported on the ground, thus effectively improving the stability of the device.

[0037] Please see Figure 1-6 The clamping blocks 7 are fixedly connected in four groups to the two sides of the sound insulation board 2, and the clamping blocks 7 are trapezoidal.

[0038] Specifically, by setting the clamping block 7, the friction can be effectively reduced when installing or removing the mounting bracket 1 and the sound insulation plate 2, making the device operate more smoothly.

[0039] Please see Figure 1-6 The connecting column 18 is fixedly connected to the bottom center of the mounting frame 1, and the connecting column 18 is movably connected between the mounting frame 1 and the support column 3.

[0040] Specifically, by setting up the connecting column 18, when the surrounding environment vibrates or shakes, the second spring column 20 can effectively play a role in shock absorption and buffering, thereby preventing the mounting bracket 1 from being shaken or blown over.

[0041] Working principle: In use, place the base 5 on the ground and insert the sound insulation plate 2 from top to bottom into the guide groove 10 opened on the side of the mounting frame 1. When the clamping block 7 fixed on the surface of the sound insulation plate 2 contacts the clamping plate 6, the clamping block 7 will push the clamping plate 6 into the mounting frame 1. When the clamping block 7 slides to the inside of the clamping plate 6, under the action of the first spring column 9, the first spring column 9 will push the clamping plate 6 outward, so that the clamping plate 6 is limited to the outer surface of the clamping block 7, thereby playing a role in clamping and fixing the sound insulation plate 2. When the construction environment has a large sound or vibration, the outer extension plate 16 is flipped out from the inside of the storage groove 12 by the action of the rotating rod 15, thereby expanding the support area of ​​the base 5. The connecting column 18 is fixedly connected between the mounting frame 1 and the support column 3, and the second spring column 20 can disperse the resonance energy and reduce the impact of resonance on the sound insulation effect.

[0042] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
