The utility model has simple and clear structure and convenient use; the manufacturing cost is low; the earplug can be better inserted into the ear canal by the pushing structure taking the T-shaped pusher as the core part, so that the noise is reduced; the sleep quality of people can be improved, and the working efficiency is improved.

Description

Detachable push earplug

Technical Field

The utility model belongs to the environmental protection equipment field relates to noise control sound equipment, concretely relates to can dismantle and impel earplug.

Background

With the rapid development of industrial production, industrial and living noises are increasing, which seriously affects the daily life and sleeping quality of people, and therefore, the noise-proof earplug is indispensable.

Noise-proof earplugs are sold on the market at present in various forms, however, the external auditory meatus of people is in a bent pipe shape, the structures of the auditory meatus of different people are different, and some auditory meatuses are irregular or flat. In daily life, the earplug cannot be completely plugged into the auditory canal.

Disclosure of Invention

Not enough to prior art exists, the utility model aims to provide a can dismantle and impel earplug, the earplug of solving among the prior art is difficult to fill in the technical problem of duct completely.

In order to solve the technical problem, the utility model discloses a following technical scheme realizes:

a detachable pushing earplug comprises an earplug body, wherein the outer diameter of the earplug body gradually decreases from the outer end to the inner end, and a pushing hole is formed in the center of the outer end of the earplug body;

the earplug body is characterized by also comprising a propeller, wherein a propelling core rod is arranged on the propeller and is inserted into the propelling hole to propel the earplug body;

the outer surface of the earplug body is also provided with a spiral ear cap.

The utility model discloses still have following technical characteristic:

the propelling hole is a conical blind hole, and the propelling core rod is a conical rod.

The taper of the pushing hole is less than or equal to that of the pushing core rod.

The outer end of the earplug body is also provided with a handle.

One corner of the propeller is provided with a rope through hole, and a hanging rope is arranged in the rope through hole.

Compared with the prior art, the utility model, following technological effect has:

the utility model has simple and clear structure and convenient use; the manufacturing cost is low; the earplug can be better inserted into the ear canal by the pushing structure taking the T-shaped pusher as the core part, so that the noise is reduced; the sleep quality of people can be improved, and the working efficiency is improved.

Drawings

Fig. 1 is a schematic view of the overall structure of the present invention.

The meaning of the individual reference symbols in the figures is: 1-earplug body, 2-pushing hole, 3-pusher, 4-pushing core rod, 5-spiral earcap, 6-handle, 7-threading hole and 8-hanging rope.

The following examples are provided to explain the present invention in further detail.

Detailed Description

It should be noted that all the components of the present invention are known in the art, and the components are not specifically described.

The following embodiments of the present invention are given, and it should be noted that the present invention is not limited to the following embodiments, and all the equivalent transformations made on the basis of the technical solution of the present application all fall into the protection scope of the present invention.

Example 1:

the embodiment provides a detachable push earplug, as shown in fig. 1, which includes an earplug body 1, wherein an outer diameter of the earplug body 1 gradually decreases from an outer end to an inner end, and a push hole 2 is formed in the center of the outer end of the earplug body 1;

still include the propeller 3, be provided with the propulsion core bar 4 on the propeller 3, impel the core bar 4 and insert and impel earplug body 1 in impelling hole 2.

The outer surface of the earplug body 1 is also provided with a spiral ear cap 5.

Specifically, the earplug body 1 can be made of silica gel, and the spiral earcap 5 is made of silica gel or high-elasticity polyester material. The earplug body 1 and the spiral earcap 5 are combined for application, so that the earplug is easy to enter the auditory canal and is more attached to the inside of the auditory canal, and the noise is effectively prevented.

As a preferable scheme of this embodiment, the pushing hole 2 is a tapered blind hole, and the pushing core rod 4 is a tapered rod. The push core rod 4 plays a role in pushing the earplugs, is convenient to operate and hold, is more beneficial to sending the earplugs into the auditory canals and is more fit. More preferably, the taper of the pushing hole 2 is equal to that of the pushing core rod 4, and the two are better jointed, so that the pushing core rod 4 can be pushed better.

As a preferable solution of this embodiment, the earplug body 1 is further provided with a handle 6 at the outer end thereof. When the user needs to remove the earplug, the user only needs to pull the handle 6 outwards.

As a preferable scheme of this embodiment, a rope threading hole 7 is provided at one corner of the propeller 3, and a hanging rope 8 is provided in the rope threading hole 7. The hanging rope 8 can be detached, so that the requirements of different people can be met, and the hanging rope can be carried about and is not easy to lose.

The utility model discloses an during the earplug use, will advance earplug body 1 earlier and tentatively put into the duct, then will advance core bar 4 through propeller 2 and insert and advance hole 2, advance hole 2 and advance core bar 4 and closely laminate together, adjust the position of earplug body 1 in the duct through propeller 2, after the adjustment is accomplished, extract and advance core bar 4, earplug body 1 stays in the duct. When the earplug needs to be taken out, the handle 6 is pulled outwards.
