Technical Field

[0001] This utility model relates to the field of sound insulation equipment technology, specifically a mobile sound barrier. Background Technology

[0002] Square dancing, a popular form of mass fitness activity, attracts numerous enthusiasts with its unique charm. It not only provides opportunities for physical exercise and stress relief but also serves as an important platform for social interaction and strengthening neighborhood relationships, enriching the leisure life of the general public. In parks, squares, and open spaces within residential communities, groups of dancers can be seen gracefully moving to lively music every evening, creating a vibrant and joyful scene.

[0003] A search revealed that Chinese Patent Publication No. CN 217267002 U discloses a movable sound barrier, comprising a fixed frame. A metal sound-insulating panel and a PC sound-insulating panel are installed on the inner side of the fixed frame, with the PC sound-insulating panel located in the middle of the metal sound-insulating panel. A scale-like sound-insulating structure is installed at the front end of the PC sound-insulating panel. A movable base structure is installed at the lower end of the fixed frame. The scale-like sound-insulating structure includes mounting blocks, a damping shaft, and scale-like sound-insulating panels. Multiple mounting blocks are installed at the front end of the PC sound-insulating panel, and the damping shaft is installed at the front end of the mounting blocks. This movable sound barrier significantly reduces sound transmission, thus greatly improving sound insulation. It also maintains a simple design, allows for left-right adjustment of the fixed frame, ensures structural strength, facilitates easy movement and adjustment, and allows for the joint installation of multiple sound barriers.

[0004] The sound barrier in the aforementioned patent still has some shortcomings. Because the existing square dance speakers lack effective sound barriers around them when playing music, most of them use ordinary baffles for sound insulation. However, ordinary baffles have poor sound insulation effect and are difficult to move flexibly, making them inconvenient to use. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a mobile sound barrier, which solves the problem that existing square dance speakers lack effective sound barriers around them when playing music. Most of them use ordinary baffles for sound insulation, but ordinary baffles have poor sound insulation effects and are difficult to move flexibly, making them inconvenient to use.

[0006] This utility model provides the following technical solution: a mobile sound barrier, including a sound insulation installation component, wherein a sound insulation plate is provided on the top of the sound insulation installation component, and two sets of stable support components are symmetrically arranged on both sides of the sound insulation plate.

[0007] The sound insulation installation assembly includes a mounting base plate, a connecting slot at the top of the mounting base plate, several connecting holes symmetrically arranged on both sides of the inner wall of the connecting slot, several mounting holes evenly arranged at the bottom of the sound insulation panel, the bottom of the sound insulation panel being inserted into the connecting slot, a connecting screw being inserted into the connecting hole, two connecting nuts symmetrically fitted on both sides of the connecting screw, a splicing slot at one end of the mounting base plate, a splicing rod at the other end of the mounting base plate, and several casters evenly installed at the bottom of the mounting base plate.

[0008] The stabilizing support assembly includes two fixed connecting frames symmetrically arranged on both sides of the sound insulation panel. A grounding support rod is inserted into the fixed connecting frame. Two first insertion holes are symmetrically opened on both sides of the fixed connecting frame. A second insertion hole is opened at the top of the grounding support rod. Fastening screws are inserted into the first and second insertion holes. Fastening nuts are fitted at both ends of the fastening screws. A third insertion hole is opened at the bottom of the grounding support rod. A grounding connection seat is provided on the bottom side of the grounding support rod. A limit socket is opened on the grounding connection seat. A counterweight is inserted into the limit socket. A fastening connecting frame is provided at the top of the grounding connection seat.

[0009] Preferred technical solution 1: The bottom side of the grounding support rod is inserted into the fastening connection frame, and two fourth insertion holes are symmetrically opened on both sides of the fastening connection frame.

[0011] Preferred technical solution three: The sound insulation board is composed of magnesium oxide board and damping adhesive.

[0012] This solution utilizes a high-density magnesium oxide board, with a butyl rubber damping layer in the middle and a polyester fiber sound-absorbing cotton bottom layer. The damping layer converts sound wave energy into heat energy, weakening low-frequency vibrations. The overall sound insulation can reach 35-45dB (equivalent to reducing the noise of a square dance speaker from 80dB to 35-45dB, close to the sound environment of a library).

[0013] Preferred technical solution four: The inner diameter of the splicing slot is the same as the diameter of the splicing rod.

[0014] This solution enables the splicing rod to connect better to the splicing slot.

[0015] Preferred technical solution five: Both ends of the grounding support rod are arc-shaped.

[0016] This design allows the grounding support rod to rotate more smoothly within the fixed connection frame and the fastening connection frame.

[0017] Compared with the prior art, this utility model provides a mobile sound barrier with the following advantages: This utility model includes a sound insulation installation assembly, on which a sound insulation panel and a stabilizing support assembly are installed. The top of the mounting base plate in the sound insulation installation assembly has a connecting slot, and the bottom end of the sound insulation panel is inserted into the connecting slot. A connecting screw passes through the mounting hole to fix the sound insulation panel to the mounting base plate. The bottom of the mounting base plate is equipped with casters, making the device more flexible in its movement and reducing the labor intensity of workers. The grounding support rod in the stabilizing support assembly, through contact with the ground and the insertion of a counterweight in the limiting socket, ensures that both sides of the sound insulation panel are stably in contact with the ground, allowing the sound insulation panel to stand upright and provide better sound insulation, making it more convenient to use.

Detailed Implementation

[0025] Please see Figure 1-4 ,

[0026] Example 1: A mobile sound barrier includes a sound insulation installation component 1, a sound insulation panel 2 is provided on the top of the sound insulation installation component 1, and two sets of stable support components 3 are symmetrically arranged on both sides of the sound insulation panel 2.

[0027] The sound insulation installation assembly 1 includes a mounting base plate 101. A connecting slot 102 is provided at the top of the mounting base plate 101. Several connecting holes 103 are symmetrically provided on both sides of the inner wall of the connecting slot 102. Several mounting holes 106 are evenly provided at the bottom of the sound insulation panel 2. The bottom of the sound insulation panel 2 is inserted into the connecting slot 102. A connecting screw 104 is inserted into the connecting hole 103. Two connecting nuts 105 are symmetrically sleeved on both sides of the connecting screw 104. A splicing slot 107 is provided at one end of the mounting base plate 101. A splicing rod 108 is provided at the other end of the mounting base plate 101. Several casters 109 are evenly installed at the bottom of the mounting base plate 101.

[0028] The stabilizing support assembly 3 includes two fixed connecting frames 301 symmetrically arranged on both sides of the sound insulation panel 2. A grounding support rod 302 is inserted into each fixed connecting frame 301. Two first insertion holes 303 are symmetrically opened on both sides of the fixed connecting frame 301. A second insertion hole 304 is opened at the top of the grounding support rod 302. Fastening screws 305 are inserted into both the first and second insertion holes 303 and 304. Fastening nuts 306 are fitted at both ends of the fastening screws 305. A third insertion hole 307 is opened at the bottom of the grounding support rod 302. A grounding connector 308 is provided on the bottom side of 02. A limit socket 309 is provided on the grounding connector 308. A counterweight 310 is inserted into the limit socket 309. A fastening frame 311 is provided on the top of the grounding connector 308. The bottom side of the grounding support rod 302 is inserted into the fastening frame 311. Two fourth sockets 312 are symmetrically provided on both sides of the fastening frame 311. Insertion studs 313 are inserted into the fourth sockets 312 and the third socket 307. Two insertion nuts 314 are symmetrically fitted on both ends of the insertion studs 313.

[0029] Example 2: The difference between this example and Example 1 is that the sound insulation board 2 is composed of a magnesium oxide board and damping adhesive.

[0030] This system, consisting of a high-density magnesium oxide board, a butyl rubber damping layer in the middle, and polyester fiber sound-absorbing cotton at the bottom, converts sound wave energy into heat energy through the damping layer, weakening low-frequency vibrations. The overall sound insulation can reach 35-45dB, which is equivalent to reducing the noise of square dance speakers from 80dB to 35-45dB, approaching the sound environment of a library.

[0031] Example 3: The difference between this example and Example 1 is that the inner diameter of the splicing slot 107 is the same as the diameter of the splicing rod 108.

[0032] This allows the splicing rod 108 to be better connected to the splicing slot 107.

[0033] Example 4: The difference between this example and Example 1 is that both ends of the grounding support rod 302 are arc-shaped.

[0034] This makes the grounding support rod 302 rotate more smoothly in the fixed connection frame 301 and the fastening connection frame 311.

[0035] In this embodiment, since the existing square dance speakers lack effective sound insulation barriers around them when playing music, most of them use ordinary baffles for sound insulation. However, ordinary baffles have poor sound insulation effect and are difficult to move flexibly, making them inconvenient to use.

[0036] In summary, in practical implementation, when users need to block the loud music played by square dancing in the square to prevent the sound from excessively affecting the daily lives of nearby residents, users can insert the bottom of the soundproof board 2 into the connecting slot 102 opened at the top of the mounting base plate 101, and then insert the connecting screw 104 into the connecting hole 103 so that the end of the connecting screw 104 passes through the mounting hole 106, and two connecting nuts 105 are symmetrically fitted on both ends of the connecting screw 104.

[0037] The sound insulation board 2 is then fastened to the mounting base plate 101. A moving wheel 109 is also installed at the bottom of the mounting base plate 101, which makes the movement of the device more flexible and greatly reduces the labor intensity of manual handling. The device can be set in multiple sets according to the size of the surrounding environment. It is spliced ​​by inserting the splicing rod 108 into the splicing slot 107 to adapt to the fence range when used.

[0038] On both sides of the sound insulation panel 2, two sets of stabilizing support components 3 are symmetrically arranged. The top of the fixed connecting frame 301 in the stabilizing support component 3 is connected to the top of the grounding support rod 302 by a fastening screw 305 passing through the second insertion hole 304. The bottom of the grounding support rod 302 is connected to the grounding connection seat 308 by a plug-in stud 313 passing through the third insertion hole 307. The grounding connection seat 308 has a limit socket 309. By inserting a counterweight 310 into the limit socket 309, the contact weight between the bottom of the grounding support rod 302 and the ground is enhanced, thereby providing more stable resistance to both sides of the sound insulation panel 2, ensuring that the sound insulation panel 2 is more stable and playing an effective sound insulation role.
