Description

Technical Field

[0001] This utility model belongs to the field of noise reduction equipment, and in particular relates to a replaceable splicing sound insulation board. Background Technology

[0002] Soundproofing panels are commonly used in soundproofing environments such as factories, conference rooms, and mixing studios. They consist of an external frame and internal soundproofing components. In existing technology, soundproofing panels include metal end frames, a metal base plate, and a porous sound-absorbing panel. Several partitions exist between the metal end frames, and sound-insulating material is filled between the partitions and between the metal end frames and the partitions. The partitions, metal end frames, metal base plate, and soundproofing panel are fixedly connected. The panels also include a Z-shaped reinforcing rib, with the four sides of the metal end frames fixedly connected to the metal base plate. At least two reinforcing ribs are located between the two end metal end frames, with one end of each rib fixedly connected to the metal base plate. Sound-insulating and sound-absorbing material is filled between the reinforcing ribs and between the reinforcing ribs and the metal end frames. The other end of the reinforcing rib is fixedly connected to the sound-absorbing panel. The metal end frames are also fixedly connected to the sound-absorbing panel.

[0003] The existing solutions described above can reduce the overall vibration of the sound insulation panel, and the metal base plate and sound-absorbing plate on the sound insulation panel are flat. However, the above devices are installed as a whole structure in the working environment. When the porous sound-absorbing plate or the internal sound insulation material is damaged or contaminated, it is difficult to clean or replace it. Therefore, there is an urgent need for a sound insulation panel that can quickly and partially replace the vulnerable parts. Utility Model Content

[0031] like Figures 1-6 As shown: A replaceable interlocking sound insulation panel, comprising:

[0032] The sound insulation component 1 is composed of a base plate 101, sound insulation cotton 102, and sound absorbing plate 103. The base plate 101 and the sound absorbing plate 103 are connected to each other, and the sound insulation cotton 102 is located between the base plate 101 and the sound absorbing plate 103.

[0033] The connecting frame 2 is composed of multiple horizontal plates 201 and multiple vertical plates 202 inserted together. The horizontal plates 201 and vertical plates 202 form a placement position for placing the sound insulation component 1. The vertical plates 202 are fixedly connected to the base plate 101.

[0034] In some embodiments, the horizontal plate 201 and the vertical plate 202 can also be connected by welding. Multiple horizontal plates 201 and multiple vertical plates 202 form multiple rectangular frames that match the sound insulation component 1. The sound insulation component 1 is set in the rectangular frame. According to the actual size requirements, the corresponding sound insulation components 1 are spliced ​​together to obtain a complete sound insulation board.

[0035] The four sides of the base plate 101 are bent to the same side to form a side plate 10101 perpendicular to the base plate 101. The end face of the side plate 10101 near the base plate 101 is in contact with the side wall of the sound insulation cotton 102, and the end face of the side plate 10101 away from the base plate 101 is in contact with the horizontal plate 201 or the vertical plate 202.

[0036] The middle part of the side plate 10101 is provided with a connecting groove 10102, and a connecting block 20201 corresponding to the connecting groove 10102 is fixed on the vertical plate 202. The connecting block 20201 is located inside the connecting groove 10102.

[0037] In this embodiment, the connecting block 20201 is a rectangular block and the connecting groove 10102 is a corresponding rectangular groove. The two cooperate with each other to form a connection structure between the connecting frame 2 and the sound insulation component 1. In other embodiments, the connecting block 20201 and the connecting groove 10102 can be structural components of any corresponding shape, such as circles or ellipses.

[0038] The bottom surface of the connecting groove 10102 has a connecting hole 10103, and the connecting block 20201 has a threaded groove corresponding to the connecting hole 10103. A connecting bolt is provided in the connecting hole 10103, and the connecting bolt passes through the connecting hole 10103 and is threaded into the threaded groove of the connecting block 20201.
