Description

Technical Field

[0001] This application relates to the field of laboratory noise reduction technology, and in particular to a noise reduction structure for a precision environmental control laboratory. Background Technology

[0002] For some laboratories with precise environmental control, the sounds of equipment outside the laboratory and the gas flow in the gas channels can generate noise inside the laboratory. This noise may threaten the accuracy and repeatability of experimental results, so soundproofing of the laboratory is necessary.

[0003] Traditional soundproofing structures involve installing soundproofing panels on the walls of the laboratory to isolate the interior from the exterior. When existing soundproofing panels are installed in a modular fashion, a gap of 2.5-3mm is usually left between two panels to allow for lateral installation and prevent warping or deformation during installation. However, the presence of this gap reduces the soundproofing effect of the panels. Utility Model Content

[0004] To address the issue of reduced sound insulation performance caused by gaps between sound insulation panels, this application provides a noise reduction structure for a precision environmental control laboratory.

[0005] The noise reduction structure for a precision environmental control laboratory provided in this application adopts the following technical solution:

[0006] A noise reduction structure for a precision environmental control laboratory includes several sound insulation panels that can be spliced ​​together. The ends of two laterally adjacent sound insulation panels are respectively a first mounting part and a second mounting part. A first connecting groove is formed on the front of the first mounting part, and a first connecting part is formed at the end of the first mounting part. A second connecting groove for the first connecting part to be inserted is formed on the back of the second mounting part, and a second connecting part that can be inserted into the first connecting groove is formed at the end of the second mounting part. Installation gaps are formed between the first connecting part and the groove wall of the second connecting groove, and between the second connecting part and the groove wall of the first connecting groove.

[0007] By adopting the above technical solution, when laterally splicing two sound insulation panels, the first connecting part is inserted into the second connecting groove and the second connecting part is inserted into the first connecting groove. The setting of the installation gap provides lateral installation margin for the installation of the sound insulation panels. By utilizing the overlap of the first connecting part and the second connecting part, it is possible to effectively prevent sound from directly propagating through the gap between the two sound insulation panels, thereby improving the sound insulation effect of the sound insulation panels.

[0008] In one specific implementation, a first snap-fit ​​groove is formed on the groove wall of the first connecting groove, and a first snap-fit ​​portion is formed on the first connecting portion. A second snap-fit ​​groove is formed on the groove wall of the second connecting groove for the first snap-fit ​​portion to be inserted into, and a second snap-fit ​​portion is formed on the second connecting portion that can be inserted into the first snap-fit ​​groove. Lateral gaps adapted to the installation gap are provided between the first snap-fit ​​portion and the second snap-fit ​​groove, and between the second snap-fit ​​portion and the first snap-fit ​​groove.

[0009] By adopting the above technical solution, the first snap-fit ​​part is inserted into the second snap-fit ​​groove, and the second snap-fit ​​part is inserted into the first snap-fit ​​groove, which improves the lateral installation strength and stability of the two sound insulation panels. The setting of the lateral gap provides a margin for the lateral installation of the sound insulation panels, and at the same time provides a release space for the lateral displacement of the sound insulation panels caused by thermal expansion and contraction, effectively avoiding the mutual squeezing between the sound insulation panels due to thermal expansion and contraction.

[0010] In one specific implementation, the first mounting part and the second mounting part are filled with limiting members in the corresponding mounting gap. The limiting members are detachable from the first mounting part and the second mounting part to form the mounting gap.

[0011] By adopting the above technical solution, when the first connecting part is inserted into the second connecting groove and the second connecting part is inserted into the first connecting groove, the first connecting part and the second connecting part abut against the corresponding limiting parts respectively. After the sound insulation board is installed on the wall, the limiting parts are removed to form an installation gap, thereby making it easier to control the width of the installation gap.

[0012] In one specific implementation, the limiting member is a rubber strip, and both the first mounting part and the second mounting part are respectively bonded to the corresponding rubber strip.

[0013] By adopting the above technical solution, the elasticity of the rubber strip can generate a certain deformation to offset the errors generated during the processing of the sound insulation board, thereby improving the convenience of sound insulation board installation.

[0014] In one specific implementation, the bottom wall of the first connecting groove and the bottom wall of the second connecting groove are respectively bonded to the corresponding rubber strip.

[0015] By adopting the above technical solution, the rubber strip is bonded to the bottom wall of the first connecting groove and the bottom wall of the second connecting groove, thereby improving the ease of disassembling the rubber strip.

[0016] In one specific implementation scheme, a first arc-shaped elastic plate is provided on the bottom wall of the first snap-fit ​​groove, and a second arc-shaped elastic plate is provided on the bottom wall of the second snap-fit ​​groove. The opening of the first arc-shaped elastic plate faces the opening of the first snap-fit ​​groove and can abut against the second snap-fit ​​part. The opening of the second arc-shaped elastic plate faces the opening of the second snap-fit ​​groove and can abut against the first snap-fit ​​part. The first snap-fit ​​part can compress the second arc-shaped elastic plate to deform, and the second snap-fit ​​part can compress the first arc-shaped elastic plate to deform.

[0017] By adopting the above technical solution, when the two sound insulation panels undergo lateral deformation due to temperature changes, the first snap-fit ​​part moves and squeezes the second arc-shaped elastic plate to deform and comes into contact with the second arc-shaped elastic plate. The second snap-fit ​​part moves and squeezes the first arc-shaped elastic plate to deform and comes into contact with the first arc-shaped elastic plate, thereby improving the sealing performance of the two sound insulation panels when they deform and improving the sound insulation effect of the sound insulation panels.

[0018] In one specific implementation, the end of the first snap-fit ​​portion forms a first arcuate portion adapted to the second arcuate elastic plate, and the end of the second snap-fit ​​portion forms a second arcuate portion adapted to the first arcuate elastic plate.

[0019] By adopting the above technical solution, the end of the first snap-fit ​​portion forms a first arc-shaped portion that adapts to the second arc-shaped elastic plate, and the end of the second snap-fit ​​portion forms a second arc-shaped portion that adapts to the first arc-shaped elastic plate. This design allows the first and second snap-fit ​​portions to better fit the corresponding arc-shaped elastic plates during insertion, thereby improving the sealing and stability of the connection, effectively preventing noise penetration, and enhancing the performance of the entire noise reduction structure.

[0020] In one specific implementation scheme, both the first arc-shaped elastic plate and the second arc-shaped elastic plate are plastic plates.

[0021] In summary, this application includes at least one of the following beneficial technical effects:

[0022] 1. When laterally splicing two sound insulation panels, the first connecting part is inserted into the second connecting groove and the second connecting part is inserted into the first connecting groove. The setting of the installation gap provides lateral installation allowance for the installation of the sound insulation panels. By utilizing the overlap of the first connecting part and the second connecting part, it is possible to effectively prevent sound from directly propagating through the gap between the two sound insulation panels, thereby improving the sound insulation effect of the sound insulation panels.

[0023] 2. By inserting the first snap-fit ​​part into the second snap-fit ​​groove and the second snap-fit ​​part into the first snap-fit ​​groove, the lateral installation strength and stability of the two sound insulation panels are improved. The lateral gap provides leeway for the lateral installation of the sound insulation panels and provides space for the lateral displacement caused by thermal expansion and contraction of the sound insulation panels, effectively preventing the sound insulation panels from squeezing each other due to thermal expansion and contraction.

[0027] The following is in conjunction with the appendix Figure 1-2 This application will be described in further detail.

[0028] This application discloses a noise reduction structure for a precision environmental control laboratory.

[0029] Reference Figure 1 A noise reduction structure for a precision environmental control laboratory includes several sound insulation panels 1 that can be spliced ​​together. The ends of two laterally adjacent sound insulation panels 1 are connected to a first mounting part 21 and a second mounting part 22, respectively. The side of the sound insulation panel 1 facing the room is the front, and the side away from the room is the back. A first connecting groove 211 is provided on the front of the first mounting part 21, and a first connecting part 212 is formed at the end of the first mounting part 21. A second connecting groove 221 for the first connecting part 212 to be inserted is provided on the back of the second mounting part 22, and a second connecting part 222 that can be inserted into the first connecting groove 211 is formed at the end of the second mounting part 22. Installation gaps 3 are formed between the first connecting part 212 and the groove wall of the second locking groove 223, and between the second connecting part 222 and the groove wall of the first locking groove 213. When the first connecting part 212 is inserted into the second connecting groove 221 and the second connecting part 222 is inserted into the first connecting groove 211, the two sound insulation panels 1 are in a flat state.

[0030] When the two sound insulation panels 1 are joined laterally, the first connecting part 212 is inserted into the second connecting groove 221 and the second connecting part 222 is inserted into the first connecting groove 211. The installation gap 3 provides lateral installation allowance for the installation of the sound insulation panels 1. By utilizing the overlap of the first connecting part 212 and the second connecting part 222, sound can be effectively prevented from directly propagating through the gap between the two sound insulation panels 1, thereby improving the sound insulation effect of the sound insulation panels 1.

[0031] Reference Figure 1 The first connecting groove 211 has a first snap-fit ​​groove 213 on its groove wall and a first snap-fit ​​part 214 on the first connecting part 212. The first snap-fit ​​part 214 is perpendicular to the first connecting part 212. The second connecting groove 221 has a second snap-fit ​​groove 223 on its groove wall for the first snap-fit ​​part 214 to be inserted into. The second connecting part 222 has a second snap-fit ​​part 224 that can be inserted into the first snap-fit ​​groove 213. The second snap-fit ​​part 224 is perpendicular to the second connecting part 222. Lateral gaps 5 that are adapted to the installation gap 3 are provided between the first snap-fit ​​part 214 and the second snap-fit ​​groove 223, and between the second snap-fit ​​part 224 and the first snap-fit ​​groove 213. The width of the lateral gap 5 is the same as the width of the installation gap 3.

[0032] When installing the two sound insulation panels 1, the first snap-fit ​​part 214 is inserted into the second snap-fit ​​groove 223, and the second snap-fit ​​part 224 is inserted into the first snap-fit ​​groove 213, which improves the lateral installation strength and stability of the two sound insulation panels 1. The lateral gap 5 provides leeway for the lateral installation of the sound insulation panels 1, and at the same time provides space for the lateral displacement of the sound insulation panels 1 caused by thermal expansion and contraction, effectively avoiding the phenomenon of the sound insulation panels 1 being squeezed against each other due to thermal expansion and contraction and causing damage to the sound insulation panels 1.

[0033] Reference Figure 1 The first snap-fit ​​groove 213 has a first arc-shaped elastic plate 215 on its bottom wall, and the second snap-fit ​​groove 223 has a second arc-shaped elastic plate 225 on its bottom wall. Both the first arc-shaped elastic plate 215 and the second arc-shaped elastic plate 225 are plastic plates. The opening of the first arc-shaped elastic plate 215 faces the opening of the first snap-fit ​​groove 213, and the back of the first arc-shaped elastic plate 215 is fixedly connected to the bottom wall of the first snap-fit ​​groove 213. The end of the second snap-fit ​​part 224 forms a second arc-shaped part 226 that is adapted to the first arc-shaped elastic plate 215. After the sound insulation panel 1 is installed, the second snap-fit ​​part 224 is inserted into the first snap-fit ​​groove 213, and the second arc-shaped part 226 abuts against the first arc-shaped elastic plate 215. As the sound insulation panel 1 deforms laterally, the second arc-shaped part 226 compresses and deforms the first arc-shaped elastic plate 215.

[0034] Reference Figure 1The opening of the second arc-shaped elastic plate 225 faces the opening of the second snap-fit ​​groove 223. The back of the second arc-shaped elastic plate 225 is fixedly connected to the bottom wall of the second snap-fit ​​groove 223. The end of the first snap-fit ​​part 214 forms a first arc-shaped part 216 that is adapted to the second arc-shaped elastic plate 225. When the sound insulation plate 1 is installed, the first snap-fit ​​part 214 is inserted into the second snap-fit ​​groove 223. The first arc-shaped part 216 abuts against the second arc-shaped elastic plate 225. As the sound insulation plate 1 deforms laterally, the first arc-shaped part 216 squeezes the second arc-shaped elastic plate 225 to deform.

[0035] Reference Figure 1 The first snap-fit ​​portion 214 has an end forming a first arc-shaped portion 216 that matches the second arc-shaped elastic plate 225, and the second snap-fit ​​portion 224 has an end forming a second arc-shaped portion 226 that matches the first arc-shaped elastic plate 215. This design allows the first snap-fit ​​portion 214 and the second snap-fit ​​portion 224 to better fit the corresponding arc-shaped elastic plates during insertion, thereby improving the sealing and stability of the connection, effectively preventing noise penetration, and improving the performance of the entire noise reduction structure. When the two sound insulation plates 1 undergo lateral deformation due to temperature changes, the first arc-shaped portion 216 moves and compresses the second arc-shaped elastic plate 225, causing it to deform and come into contact with the second arc-shaped elastic plate 225. The second arc-shaped portion 226 moves and compresses the first arc-shaped elastic plate 215, causing it to deform and come into contact with the first arc-shaped elastic plate 215. This improves the sealing of the two sound insulation plates 1 during deformation and enhances the sound insulation effect of the sound insulation plates 1.

[0036] Reference Figure 2 The first mounting part 21 and the second mounting part 22 are filled with limiting members 4 in the corresponding mounting gaps 3. In this embodiment, the limiting member 4 is a rubber strip 41. The bottom wall of the first connecting groove 211 and the bottom wall of the second connecting groove 221 are respectively bonded to the corresponding rubber strip 41. After the sound insulation panel 1 is installed, the rubber strip 41 is torn off the sound insulation panel 1 to form the mounting gap 3. During the installation of the sound insulation panel 1, the elasticity of the rubber strip 41 can generate a certain deformation to offset the error generated during the processing of the sound insulation panel 1, thereby improving the convenience of the installation of the sound insulation panel 1. The bonding of the rubber strip 41 to the bottom wall of the first connecting groove 211 and the bottom wall of the second connecting groove 221 improves the convenience of disassembling the rubber strip 41.

[0037] The implementation principle of the noise reduction structure for a precision environmental control laboratory in this application embodiment is as follows: When laterally splicing two sound insulation panels 1, the first connecting part 212 is inserted into the second connecting groove 221, the second connecting part 222 is inserted into the first connecting groove 211, the first snap-fit ​​part 214 is inserted into the second snap-fit ​​groove 223, and the second snap-fit ​​part 224 is inserted into the first snap-fit ​​groove 213, thereby improving the lateral installation strength and stability of the two sound insulation panels 1. The setting of the installation gap 3 and the lateral gap 5 provides lateral installation margin for the installation of the sound insulation panels 1. By utilizing the overlap of the first connecting part 212 and the second connecting part 222, sound can be effectively prevented from directly propagating through the gap between the two sound insulation panels 1, thereby improving the sound insulation effect of the sound insulation panels 1. At the same time, it provides release space for the lateral displacement of the sound insulation panels 1 caused by thermal expansion and contraction, effectively preventing the sound insulation panels 1 from being damaged due to mutual compression caused by thermal expansion and contraction.

[0038] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
