Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1-2, a portable noise tester comprises a noise tester 1, a display screen 2 and a key 3 are fixedly mounted on the surface of the noise tester 1, a probe 4 is mounted at the top height of the noise tester 1, and the display screen 2, the key 3 and the probe 4 are all in signal connection with a processor of the noise tester 1. The outer side of the probe 4 is sleeved with a wind-proof ball 5, and the wind-proof ball 5 is arranged to reduce wind blowing sound and improve the accuracy of detection noise.

Referring to fig. 2-3, the outer side of the noise tester 1 is slidably connected with a plastic sleeve 6, and the front surface of the plastic sleeve 6 is provided with an opening corresponding to the key 3, so that the plastic sleeve 6 can be conveniently slid downwards and then touched with the key 3 to input numerical values and other operations. The top of the plastic sleeve 6 is hinged to a plastic cover 7, a first magnetic block 8 is embedded in the surface of one end, far away from the hinged point, of the plastic cover 7, a second magnetic block 9 is embedded on the right side of the top of the plastic sleeve 6, and the plastic cover 7 is magnetically attracted and connected with the plastic sleeve 6 through the first magnetic block 8 and the second magnetic block 9 in a closed mode. A magnet III 10 is embedded on the left side of the plastic sleeve 6, and the plastic cover 7 is connected with the plastic sleeve 6 in an opening-closing magnetic attraction manner through a magnet I8 and the magnet III 10.

Referring to fig. 2-3, sliding bars 61 are fixedly mounted on both sides of the inner wall of the plastic sheath 6, a protrusion 62 is fixedly mounted on the inner wall of the plastic sheath 6 and between the sliding bars 61, a groove corresponding to the protrusion 62 is formed on the housing of the noise tester 1, and the plastic sheath 6 is movably clamped with the housing of the noise tester 1 through the protrusion 62 and the groove.
