Problems solved by technology
The inventor found the following problems in the prior art during the process of realizing the present invention: 1. When the device is in use, it is impossible to limit the angle of the movable parts, so that the movable parts cannot be limited when the angle is adjusted, so that the movable parts cannot be positioned at the same time. During work, it is easy to loosen; 2. The equipment in the device cannot freely adjust the working position according to the use environment, which indirectly reduces the convenience of use of the device

The invention relates to the technical field of road noise sound insulation devices, in particular to a modular sound insulation device for road municipal house building capable of avoiding noise concentration, which comprises a support frame, a limiting groove is formed in one side of the outer wall of the support frame, a rotating shaft movably penetrates through the inner wall of the limiting groove, and a butt joint rod is fixedly connected to the outer wall of the rotating shaft. According to the improved road noise insulation device, when the device runs, after a butt joint rod rotates to a specified angle, an elastic column generates resilience force to drive a connecting plate to stretch out and draw back, and the connecting plate drives a movable head to stretch out and draw back synchronously, so that the movable head is clamped into a clamping groove in the butt joint rod, and the working angle of the butt joint rod is rapidly limited; unnecessary loosening is prevented when the butt joint rod is used in the device, the working stability of parts in the device is improved, meanwhile, in the stretching and retracting process of the connecting plate, the connecting plate can slide on the limiting rod in a limiting mode through the limiting sleeve, and the connecting plate is prevented from inclining in the stretching and retracting sliding process.
Description
technical field [0001] The invention relates to the technical field of road noise sound insulation devices, in particular to a modular sound insulation device for highway municipal house construction which avoids noise concentration. Background technique [0002] Road sound insulation devices generally use sound insulation boards as the main material. Sound insulation boards are a kind of plate that acts on the sound insulation effect. There are building sound insulation and structure sound insulation classification. Sound insulation boards can not block all frequencies of sound, and objects have natural resonance frequencies. , The sound close to the resonant frequency of the object, the sound insulation effect of the sound insulation board is significantly reduced, and the sound insulation equipment is generally used in the construction of highway municipal houses. daily life of residents. [0003] The existing patent (publication number: CN214530273U) discloses a sound i...
