Abstract

This utility model relates to the technical field of noise protection products, and discloses a detachable push-in earplug, including a thin-film earplug and an outer tube. An inner tube is slidably connected inside the outer tube, and multiple hooks are fixedly connected to the top of the inner tube. Two grooves are formed on the inner wall of the outer tube, and a reset assembly is provided on the inner wall of the outer tube. The reset assembly includes two sliders, which are fixedly connected to the outer wall of the inner tube. The outer wall of the slider is slidably connected to the inner wall of the groove. A spring is fixedly connected to the top of the slider. A silicone pad is fixedly connected to the side of the inner tube away from the hooks, and the end of the spring away from the slider is fixedly connected to the inner wall of the outer tube. In this utility model, by using polyethylene as the material for the earplug, the thin-film earplug is small in size, does not fall off, is more comfortable, and becomes very soft when crumpled into a ball. After being inserted into the ear a couple of times, it molds to the shape of the ear canal and fits perfectly, resulting in better sound insulation.
