The invention relates to the field of telephone booths, in particular to a sound insulation telephone booth based on combination of a
metal plate module and an aluminum profile module, through the
embedded design of a positioning structure and a matching structure of a plate
assembly, alignment of adjacent plate assemblies is facilitated, complex positioning operation is not needed, and the installation time is greatly shortened. Stable support is provided through the aluminum profile modules, the situation that the sound insulation performance is reduced due to structure looseness is avoided, and the
enclosure structure formed by the
metal plate modules is matched, so that connecting gaps can be effectively reduced, sound leakage is avoided, and the sound insulation effect is improved. The
modular design of the
metal plate modules and the aluminum profile modules supports factory
prefabrication, all the modules can be independently produced, detected and packaged, the transportation size is reduced, the logistics efficiency is improved, in addition, due to the
modular design, later maintenance and function upgrading are more convenient, and only corresponding modules need to be replaced. The problems that a traditional
spare part assembly type sound insulation telephone booth is complex in installation, unstable in sound insulation performance and high in comprehensive cost are solved.
