Abstract
A kind of anti-dropout noise reduction earplug, including polyurethane sponge main body, hollow projection is set in the outer surface of polyurethane sponge main body；Slidable rigid plastics rod, the bottom connection plastics chuck of rigid plastics rod are provided with polyurethane sponge main body；In use, being adjusted to correct position from the insertion rigid plastics rod of polyurethane sponge main body；Again with thumb, forefinger and middle finger come back rotation polyurethane sponge main body to thinner state；Then auricle is up carried, while whole polyurethane sponge main body is inserted into duct, is placed in correct position；Polyurethane sponge body tail section is finally pressed with forefinger to expand completely to it；The utility model, which has, to be prevented from coming off, noise reduction clear advantage.
Description
Technical field
The utility model is related to a kind of earplug, more particularly to a kind of anti-dropout noise reduction earplug.
Background technology
Noise reduction earplug applies in general to protect hearing and sleep need in noisy environment, and traditional noise reduction earplug is generally one
Individual entirety, and surface is smooth, and it is the disadvantage is that, easy to fall off during being difficult insertion duct and use, and more presence can make
The shortcoming that user's experience is deteriorated, it is impossible to reach noise reduction purpose.
The content of the invention
In order to overcome the above-mentioned deficiencies of the prior art, the purpose of this utility model is to provide a kind of anti-dropout noise reduction ear
Plug, with decrease of noise functions substantially, the characteristics of facilitating insertion into difficult for drop-off in duct, use.
To achieve these goals, the technical solution adopted in the utility model is：
A kind of anti-dropout noise reduction earplug, including polyurethane sponge main body 1, are set in the outer surface of polyurethane sponge main body 1
Hollow raised 3；Slidable rigid plastics rod 2, the bottom connection modeling of rigid plastics rod 2 are provided with polyurethane sponge main body 1
Expect chuck 4.
The beneficial effects of the utility model：
The inside of polyurethane sponge main body 1 is provided with rigid plastics rod 2, so the characteristics of facilitating insertion into duct, and not
Easily hurt duct；Because the surface of polyurethane sponge main body 1 is provided with hollow raised 3, so being difficult to take off in use
The characteristics of falling, and sound reflect the purpose for reaching noise reduction in hollow raised 3.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
The utility model is described in further detail below in conjunction with the accompanying drawings.
It is shown in Figure 1, a kind of anti-dropout noise reduction earplug, including polyurethane sponge main body 1, in polyurethane sponge main body 1
Outer surface set hollow raised 3；Slidable rigid plastics rod 2, rigid plastics rod 2 are provided with polyurethane sponge main body 1
Bottom connection plastics chuck 4.
Operation principle of the present utility model is：
In use, inserting rigid plastics rod 2 in the cavity of polyurethane sponge main body 1, correct position is adjusted to；Again with thumb,
Forefinger and middle finger carry out back rotation polyurethane sponge main body 1 to thinner state；Then auricle is up carried, while by whole polyurethane
The insertion duct of sponge main body 1 is placed in correct position；The afterbody of polyurethane sponge main body 1 is finally pressed with forefinger to expand completely i.e. to it
Can.
