DETAILED DESCRIPTION

[0025] The utility model will now be described in further detail with reference to the accompanying drawings.

[0026] See also Figure 1-5 As shown, in this embodiment, a noise monitor that is convenient for adjusting the monitoring angle is provided, comprising: a box body 1, a noise monitor 8 is installed in the box body 1, a slot 3 is opened on one side of the box body 1, a movable frame 4 is slidably matched in the slot 3, a first telescopic rod 5 is rotatably matched in the movable frame 4, and a noise sensor 6 electrically connected to the noise monitor 8 is movably matched at the upper end of the first telescopic rod 5, wherein a plurality of universal wheels 2 are installed at the bottom of the box body 1 to facilitate the movement of the box body 1 to any monitoring location, the noise monitor 8 includes a sound level meter, a frequency analyzer, a real-time analyzer, a sound intensity analyzer, a noise level analyzer, a noise dose meter, an automatic recorder and a tape recorder, etc., and the noise sensor 6 receives the noise and transmits the noise to the noise monitor 8 for monitoring;

[0027] An arcuate groove 9 is provided on one side of the box body 1 , a slider 12 is slidably fitted in the arcuate groove 9 , a supporting elastic clip 7 corresponding to the first telescopic rod 5 is installed on one side of the slider 12 , and a limit assembly 13 is installed between the arcuate groove 9 and the slider 12 .

[0028] By means of the arcuate groove 9 provided on the box body 1, when the first telescopic rod 5 is flipped left or right to adjust the angle of the noise sensor 6, the slider 12 moves in the arcuate groove 9, and the supporting elastic clip 7 moves along the arcuate groove 9 on one side of the box body 1. The supporting elastic clip 7 can be limited and fixed in the arcuate groove 9 by the limiting component 13, and the supporting elastic clip 7 can always support the first telescopic rod 5, so as to facilitate flipping the first telescopic rod 5 to adjust the angle of the noise sensor 6. By movably fitting the noise sensor 6 at the upper end of the first telescopic rod 5, the noise sensor 6 can be adjusted to any angle at the upper end of the first telescopic rod 5, so that the noise sensor 6 can receive noises in different propagation directions, thereby improving the accuracy of noise monitoring.

[0029] like Figure 2 As shown, a second telescopic rod 10 is installed between the movable frame 4 and the noise monitor 8 of this embodiment, a collar 11 is sleeved around the second telescopic rod 10, and the first telescopic rod 5 is installed on the collar 11;

[0030] The first telescopic rod 5 contracts to reset the noise sensor 6 thereon, and then the first telescopic rod 5 is turned over. The first telescopic rod 5 is rotated and turned ninety degrees on the second telescopic rod 10 through the ring 11 to enter the movable frame 4. The movable frame 4 is then pushed into the slot 3, and the second telescopic rod 10 is squeezed and contracted, thereby facilitating the storage of the noise sensor 6 inside the box 1.
