Example

[0031] See attached Figures 1 to 6 A kind of explosion-proof personal sound exposure meter includes a personal sound exposure meter body 1, which is connected to a microphone 4 through a sound transmission line 3. A storage mechanism 2 for storing the sound transmission line 3 is arranged on the back of the personal sound exposure meter body 1. The storage mechanism 2 includes a protective sleeve 21. A mounting groove 24 is arranged on the back of the personal sound exposure meter body 1. The protective sleeve 21 is rotatably installed in the mounting groove 24. A winding mechanism 5 is fixedly arranged in the protective sleeve 21. A wire dialing mechanism 25 and a wire wiping mechanism 26 are arranged on the protective sleeve 21.

[0032] A protective cover 22 is provided at one end of the protective sleeve 21 away from the personal sound exposure meter body 1 , and a handle 23 is provided on the protective cover 22 .

[0033] The wire-shifting mechanism 25 comprises a slide groove 251 provided on the protective sleeve 21 , a slider 252 is slidably mounted in the slide groove 251 , and a wire-shifting rod 253 is provided on the slider 252 .

[0034] The thread-wiping mechanism 26 comprises a threading hole 261 , an installation block 262 is arranged outside the threading hole 261 , and a thread-wiping sponge 263 is detachably mounted on the installation block 262 .

[0035] The winding mechanism 5 includes a winding drum 51, and a first limit plate 52 and a second limit plate 53 are respectively arranged on both sides of the winding drum 51. The winding drum 51 is rotatably connected to the second limit plate 53, and the second limit plate 53 is fixedly installed on the personal sound exposure meter body 1 through a connecting block 54. The winding drum 51 is fixedly connected to the first limit plate 52, and the first limit plate 52 is fixedly connected to the protective sleeve 21.

[0036] At least two threading holes 261 are provided to facilitate cleaning of the two ends of the sound transmission line 3 . At the same time, the plurality of threading holes 261 can also adjust the threading position of the sound transmission line 3 .

[0037] Working principle: By turning the handle 23, the protective sleeve 21 is driven to rotate in the installation groove 24. When the protective sleeve 21 rotates, the winding drum 51 is driven to rotate through the first limiting disk 52. The winding drum 51 rotates around the second limiting disk 53, so that the sound line 3 is wound on the winding drum 51. The sound line 3 can be wound up through the storage mechanism 2. During the winding process, the position of the wire lever 253 is adjusted through the slider 252 and the slide groove 251, so that the winding position of the sound line 3 can be adjusted to prevent the sound line 3 from piling up in the same position. Through the setting of the wire wiping mechanism 26, when the sound line 3 is wound up and stored by the storage mechanism 2, the sound line 3 contacts the wire wiping sponge 263, and the dust on the surface of the sound line 3 is wiped off, so that the sound line 3 can be kept clean.

[0038] The above-mentioned embodiments only express a certain implementation method of the utility model, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the patent of the utility model.
