Description

Technical Field

[0001] The utility model relates to the technical field of noise detection equipment, and more specifically to an outdoor microphone protection unit. Background Art

[0002] The outdoor unit refers to a device for measuring environmental noise outdoors. It contains an outdoor microphone, a windproof ball, bird-proof spikes, a rain cover and rigid structural parts. It is mainly used outside factories, transportation places (such as roadsides), living places, construction sites, etc. to measure outdoor environmental noise, so as to facilitate the supervision or control of environmental noise.

[0003] Most of the outdoor units in the prior art are split structures. When sending them for inspection, the protective cover is removed to calibrate the outdoor microphone. However, this split structure is extremely inconvenient when removing the protective cover. When removing it, the various parts are scattered, and the wires must be soldered off, making it impossible to disassemble in an orderly manner. In addition, the scattered parts are very likely to be lost, resulting in many parts being missing when they need to be reset and assembled after the inspection is completed, which ultimately causes the outdoor unit to be directly scrapped, wasting a lot of resources. Moreover, even if the parts are not lost, when resetting and installing the protective cover, the inspection personnel must first understand the product structure diagram in order to assemble the various parts completely correctly and smoothly. During the assembly process, the wires must be soldered, which is extremely inconvenient.

[0004] Therefore, how to provide an outdoor microphone protection unit that does not require assembly and is easy to install is a problem that those skilled in the art urgently need to solve. Utility Model Content
