[0033] In this embodiment: by no longer using a larger support, but installing the quick-mounting box 21 at the rear side of the portable sound level meter 1 through bolting or magnetic attraction, when long-time detection is needed, the adjustment top plate 31 is taken out, the carrying volume is greatly reduced compared with the traditional support, at the same time, the two groups of linkage dials 23 inside the quick-mounting block 22 in front of the adjustment top plate 31 are compressed, the linkage dials 23 are simultaneously slid inward, the clamping plates 24 at the bottom of the linkage dials 23 are simultaneously inward, when the clamping plates 24 are inward, the telescopic columns 25 between the clamping plates 24 and the quick-mounting block 22 and the compression springs 26 outside the telescopic columns 25 are respectively compressed, the elastic potential energy is accumulated, the distance between the two clamping plates 24 is shortened by the linkage dials 23, until the total length is less than the entrance distance of the quick-mounting box 21, then the quick-mounting block 22 is inserted into the quick-mounting box 21, after the clamping plates 24 penetrate the quick-mounting box 21, the restriction on the linkage dials 23 is released, under the repulsion of the telescopic columns 25 and the compression springs 26 outside the telescopic columns 25, the clamping plates 24 are quickly ejected, the distance between the clamping plates 24 is increased, the bottom of the quick-mounting block 22 is limited, so that it cannot be pulled out of the quick-mounting box 21, thereby the sound level meter 1 is installed outside the adjustment top plate 31.

[0036] In the embodiment, the knob 35d outside the fixed base plate 32 is twisted to rotate the coaxial rotating block 35c, the pull rods 35b on both sides of the rotating block 35c rotate along the axis outside the rotating block 35c, and the two linkage rods 35a are pulled inward at the same time. Since the linkage rods 35a are fixedly connected with the sliding block 33, the two clamping rods 34 are simultaneously clamped inward to fix the selected target by manually adjusting the knob 35d. The clamping surface of the clamping rod 34 is provided with a pattern to increase the friction. When the knob 35d is rotated, the ratchet 35e outside the rotating point of the rotating block 35c is followed, the pawl 35f is disengaged from the tooth groove and then re-engaged into the tooth groove through the torsional spring 35g to limit the rotation of the ratchet 35e in one direction, so that the ratchet 35e is prevented from rotating in one direction to avoid the loosening of the clamping rod 34 caused by the reverse rotation of the knob 35d. When the pawl 35f is removed, the knob 35d is reversely rotated to disassemble, the sliding block 33 is rotated to the outermost side, the clamping rod 34 is turned over and stored in the sliding groove of the sliding block 33 inside the fixed base plate 32, and the outside positioning magnetic attraction 5 is fixed to reduce the overall volume and facilitate carrying.

[0039] In the embodiment, the electronic telescopic rod 4 can be used to adjust the angle of the sound level meter 1 after installation, and can also be used for pre-adjustment to facilitate manual installation by personnel. The positioning magnetic attraction 5 can be used to store the clamping rod 34.

[0040] Working principle: when outdoor noise detection is carried out, short-time detection or long-time detection is usually required according to noise detection requirements and noise detection objects. When short-time detection is carried out, it is more convenient to directly detect by using a portable sound level meter 1. However, when long-time detection is carried out, it is inconvenient to carry and recycle a fixed installation type sound level meter 1. In the prior art, a portable sound level meter 1 is converted into an installation type sound level meter 1 for detection by using a priority installation support. However, the extra carrying of a large support reduces its portability, and the installation point selection is difficult and the support stability is poor in bad weather. Therefore, a large support is not carried any more, and a quick mounting box 21 is mounted on the rear side of the portable sound level meter 1 by means of bolting or magnetic attraction. When long-time detection is required, the adjusting top plate 31 with a carrying volume greatly reduced compared with a traditional support is taken out, and at the same time, the two groups of linkage tabs 23 inside the quick mounting block 22 in front of the adjusting top plate 31 are pressed tightly. The linkage tabs 23 slide inward at the same time, and the clamping plates 24 at the bottom of the linkage tabs 23 are also inward at the same time. At the same time, the clamping plates 24 are pressed tightly, and the telescopic columns 25 between the clamping plates 24 and the compression springs 26 outside the clamping plates 24 are also pressed tightly. The elastic potential energy is accumulated. When the distance between the two clamping plates 24 is shortened by pressing the linkage tabs 23, and the total length is less than the entrance distance of the quick mounting box 21, the quick mounting block 22 is inserted into the quick mounting box 21 in this state. After the clamping plates 24 penetrate through the quick mounting box 21, the linkage tabs 23 are released, so that the quick mounting block 22 can be quickly ejected under the back thrust of the telescopic columns 25 and the compression springs 26 outside the telescopic columns 25. The distance between the clamping plates 24 is increased to limit the bottom of the quick mounting block 22, so that the quick mounting block 22 cannot be taken out of the quick mounting box 21. Thus, the sound level meter 1 is mounted on the outside of the adjusting top plate 31. After installation is completed, an outdoor rod body is selected as a bearing carrier for long-time detection. The rod body is not limited to wooden, metal or other building environment carriers in outdoor scenes, such as thin trees and street lamp posts. After the bearing carrier is selected, the clamping rods 34 on the rear side of the fixed bottom plate 32 are taken out from the sliding recesses of the sliding blocks 33, and the adsorption of the positioning magnetic attraction 5 is released. After the two groups of clamping rods 34 are located on the two sides of the selected object, the electronic telescopic rod 4 is started to preliminarily adjust the adjusting top plate 31 along the shaft outside the fixed bottom plate 32. After the space between the adjusting top plate 31 and the fixed bottom plate 32 is sufficient for manual adjustment, the rotation knob 35d outside the fixed bottom plate 32 is twisted to rotate the rotation knob 35d and the rotating block 35c coaxial with the rotation knob 35d. In the process of rotating the rotating block 35c, the pull rods 35b on the two sides of the rotating block 35c will rotate around the shaft outside the rotating block 35c, and the linkage rods 35a on the two sides will be pulled inward at the same time. The linkage rods 35a are fixedly connected with the sliding blocks 33, so that the clamping rods 34 on the two sides are clamped and fixed to the selected object by twisting the rotation knob 35d and manual adjustment.And the clamping surface of the clamping rod 34 is provided with a texture to increase the clamping friction, and in the process of rotating the knob 35d, the ratchet 35e outside the rotating point of the rotating block 35c will follow the rotation, and the pawl 35f will keep out of the tooth groove of the ratchet 35e when the ratchet 35e rotates in one direction, and will be re-engaged into the tooth groove to limit the ratchet 35e through the torsional spring 35g. The effect of avoiding the effect of the knob 35d back rotation causing the clamping rod 34 to loosen, and when not in use, the pawl 35f is removed and reversed to remove, when removing, the sliding block 33 is rotated to the outermost side, and the clamping rod 34 can be turned over and stored in the sliding groove of the sliding block 33 inside the fixed bottom plate 32 for storage, and fixed through the outside positioning magnetic attraction 5, thereby reducing the overall size for easy carrying, and the above-mentioned way can be flexibly selected and installed, without reducing the portability of the portable sound level meter 1 itself, and can be switched between short-term detection and long-term fixed detection, and the installation height is selected by human, and after installation, the electronic telescopic rod 4 can be further adjusted to adjust the angle of rotation, so as to adjust the position of the sound level meter 1 receiver, and improve the utilization efficiency of the sound level meter 1.

[0041] The above is only a preferred embodiment of the present application, and is not intended to limit the present application. Any modification, equivalent replacement and improvement within the spirit and principles of the present application shall be included in the protection scope of the present application.
