Description

Technical Field

[0001] This utility model relates to the field of building indoor noise reduction technology, specifically a building indoor noise reduction device. Background Technology

[0002] Noise reduction, as the name suggests, is about reducing the impact of noise on people. Sound absorption noise reduction is a method of controlling the intensity of noise along the transmission path. The sound absorption effect of objects is universal. The sound absorption effect is not only related to the sound-absorbing material, but also to the sound-absorbing structure selected. This technology is mainly used in indoor spaces.

[0003] For example, patent document CN 212078295 U discloses an indoor noise reduction device, which includes: a mounting body, multiple connectors, and multiple sound-absorbing panels. The connectors are spaced apart on the mounting body, and each connector has a slot. The sound-absorbing panels are installed in the gaps between adjacent connectors, with both sides of the sound-absorbing panels respectively engaging the slots of adjacent connectors. In use, the multiple connectors are first assembled onto the mounting body to form a mounting frame for the sound-absorbing panels. Then, the sound-absorbing panels are simply inserted into the slots of the connectors, and the slots of adjacent connectors simultaneously engage and fix the corresponding sides of the sound-absorbing panels, thus installing the sound-absorbing panels on the indoor noise reduction device. When installing the sound-absorbing panels, the indoor noise reduction device does not require any other auxiliary equipment for support and positioning, making installation more convenient.

[0004] However, when this structure is used for actual indoor noise reduction in buildings, it cannot guarantee the tightness of the connection between the various sound-absorbing panels. The connection points are often unstable, which affects the overall indoor noise reduction effect. At the same time, the equipment cannot perform sound insulation enhancement between the upper and lower sound-absorbing panels, causing sound to seep out at the joints, affecting the overall indoor noise reduction effect and failing to meet daily use needs. Therefore, it is urgent to design an indoor noise reduction device for buildings to solve the above problems. Utility Model Content

[0005] The purpose of this utility model is to provide a building indoor noise reduction device to solve the problems mentioned in the background art. When the existing structure is used for actual building indoor noise reduction, it cannot guarantee the tightness of the connection between each sound-absorbing panel. The connection is often unstable, which affects the overall indoor noise reduction effect. At the same time, the device cannot perform sound insulation enhancement operation between the upper and lower sound-absorbing panels, which causes sound to seep out at the joints, affecting the overall indoor noise reduction effect and failing to meet the needs of daily use.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a building indoor noise reduction device, including a sound-absorbing panel, a first mounting column is movably connected to one side of the sound-absorbing panel, and a second mounting column is movably connected to the other side of the sound-absorbing panel, wherein sound-absorbing columns are provided inside both the first mounting column and the second mounting column.

[0007] A joint strip seat is movably connected to the bottom end of the sound-absorbing panel, an upper mating plate is fixedly connected to the top end of the joint strip seat, and a lower mating plate is fixedly connected to the bottom end of the joint strip seat.

[0008] Preferably, the interior of the seam strip seat is provided with a sound insulation groove, and the inner walls of the sound insulation groove are provided with sound-absorbing cotton pads on both sides.

[0009] Preferably, the two ends of the seam strip seat are provided with sealing pads.

[0010] Preferably, the first and second mounting columns are provided with insertion slots on both sides, and the inner wall of the insertion slots is provided with magnetic strips.

[0011] Preferably, the sound-absorbing panel is provided with mating pads at both the upper and lower ends.

[0012] Preferably, magnetic seats are provided on both sides of the sound-absorbing panel, and the magnetic seats are adapted to the first mounting column and the second mounting column.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] This building interior noise reduction device, through its sound-absorbing panels, first mounting columns, second mounting columns, sound-absorbing columns, insertion slots, magnetic strips, and magnetic bases, allows for the stable assembly of multiple sound-absorbing panels for building interior noise reduction. In actual use, workers first insert the sides of the sound-absorbing panels into the sides of the first and second mounting columns. At this point, the magnetic bases on both sides of the sound-absorbing panels can be fitted into the insertion slots on both sides of the first and second mounting columns, and magnetically fixed to the magnetic strips on the inner walls of the insertion slots. This design allows for the rapid and stable assembly of multiple sound-absorbing panels. Furthermore, the sound-absorbing panels, limited by the first and second mounting columns, do not directly adhere to or squeeze out of the building walls; the gaps allow the sound-absorbing panels to achieve better sound insulation and noise reduction effects, demonstrating the practicality of the device design.

[0015] This building interior noise reduction device, through the installation of joint strip seats, upper and lower joint plates, sound insulation grooves, sound-absorbing cotton pads, sealing pads, and joint pads, further enhances the overall performance of the equipment. In daily use, staff can align the joint strip seats with the upper and lower joint plates and the upper joint plates at the upper and lower joint pads of the sound-absorbing panels. The joint strip seats are also sealed together using the sealing pads at both ends. Then, through the sound-absorbing cotton pads on both sides of the sound insulation groove inside the joint strip seat and the hollow groove structure in the center, effective sound insulation protection is achieved at the joint of the upper and lower sound-absorbing panels, improving the overall noise reduction effect of the sound-absorbing panels in the building interior and demonstrating the comprehensiveness of the equipment design.

[0023] A building interior noise reduction device includes a sound-absorbing panel 1. A first mounting column 2 is movably connected to one side of the sound-absorbing panel 1, and a second mounting column 3 is movably connected to the other side of the sound-absorbing panel 1. Sound-absorbing columns 4 are provided inside both the first mounting column 2 and the second mounting column 3. Insertion slots 11 are provided on both sides of the first mounting column 2 and the second mounting column 3. Magnetic strips 12 are provided on the inner walls of the insertion slots 11. Abutment pads 13 are provided at the upper and lower ends of the sound-absorbing panel 1. Magnetic seats 14 are provided on both sides of the sound-absorbing panel 1. The magnetic seats 14 are adapted to the first mounting column 2 and the second mounting column 3. The magnetic seats 14 on both sides of the sound-absorbing panel 1 can be inserted into the insertion slots 11 on both sides of the first mounting column 2 and the second mounting column 3, and are magnetically fixed to the magnetic strips 12 on the inner walls of the insertion slots 11. This design allows for the rapid and stable assembly of multiple sound-absorbing panels 1.

[0024] The joint strip seat 5 is movably connected to the bottom end of the sound-absorbing panel 1. The top end of the joint strip seat 5 is fixedly connected to the upper butt plate 6, and the bottom end of the joint strip seat 5 is fixedly connected to the lower butt plate 7. The joint strip seat 5 has a sound insulation groove 8 inside. The inner walls of the sound insulation groove 8 are provided with sound-absorbing cotton pads 9. The two ends of the joint strip seat 5 are provided with sealing pads 10. Through the sound-absorbing cotton pads 9 on both sides of the sound insulation groove 8 inside the joint strip seat 5 and the hollow groove structure in the center, effective sound insulation protection is performed at the joint of the upper and lower sound-absorbing panels 1, thereby improving the overall indoor noise reduction effect of the sound-absorbing panel 1.

[0025] Working principle: During use, the user first inserts the sound-absorbing panel 1 into the sides of the first mounting column 2 and the second mounting column 3. At this time, the magnetic seats 14 on both sides of the sound-absorbing panel 1 can be fitted into the insertion slots 11 on both sides of the first mounting column 2 and the second mounting column 3, and are magnetically fixed to the magnetic strips 12 on the inner wall of the insertion slots 11. This design allows for the quick and stable assembly of multiple sound-absorbing panels 1. Simultaneously, under the constraint of the first mounting columns 2 and the second mounting columns 3, the sound-absorbing panel 1 will not be directly pressed or squeezed out of the building wall. The gap allows the sound-absorbing panel 1 to achieve better sound insulation and noise reduction. In daily use, the staff can fit the joint strip seat 5 with the joint strip seat 5 at the upper and lower ends and the upper connecting plate 6 to the connecting pads 13 at the upper and lower ends of the sound-absorbing panel 1. The joint strip seats 5 are also sealed together by the sealing pads 10 at both ends. Then, through the sound-absorbing cotton pads 9 on both sides of the sound insulation groove 8 inside the joint strip seat 5 and the hollow groove structure in the center, effective sound insulation and protection are carried out at the joint of the upper and lower sound-absorbing panels 1, thereby improving the overall indoor noise reduction effect of the sound-absorbing panel 1. The above is the complete working principle of this utility model.
