Sound level meter with fixing device and fixing method thereof

Abstract

The invention discloses a sound level meter with a fixing device, and belongs to the technical field of sound level meters. An accommodation groove is formed in the front side wall of a fixing device,a clamping connecting passage is formed in the middle of the side wall of the side, away from an opening, of the accommodation groove, hinge supporting frames are fixedly arranged on both left and right sides of the side wall of the side, away from the opening, of the accommodation groove, the tops of the two groups of the hinge supporting frames are movably connected with guiding plates throughhinge shafts, supporting devices are hinged to the rear ends of the sides, away from each other, of the two groups of the guiding plates, inserting blocks which are matched with the clamping connecting passage are fixedly arranged at the front end of a sound level meter body, guiding rods are fixedly connected with the sides, away from the inserting blocks, of the two groups of the clamping blocks, and two groups of moving cavities are formed in an inner cavity of the fixing device. Limiting in left-right and front-back directions of the sound level meter can be achieved to achieve clamping fixing, and the detection height of the sound level meter body can be adjusted.

Description

technical field [0001] The invention relates to the technical field of sound level meters, in particular to a sound level meter with a fixing device and a fixing method thereof. Background technique [0002] Sound level meters are widely used in vehicle passing noise testing. Generally, sound level meters are fixed at the position and height required by national standards through brackets and bases, so as to complete the detection of noise. The traditional sound level meter is fixed by bolts. This fixing method is unstable in operation, and at the same time, there is no positioning structure for the sound level meter, and there is no limit structure for the sound level meter itself, so the fixing degree of the sound level meter is not high, and at the same time, the height adjustment of the sound level meter It has no real-time adjustable function, which reduces work efficiency and is not practical. Therefore, we propose a sound level meter with a fixing device and a fixing ...
