Abstract

The invention discloses a stopper. The stopper comprises a hemispherical buffer layer (1), one end of the hemispherical buffer layer (1) is connected with a rhombohedral fixing frame (2), a notch is formed in the middle of the rhombohedral fixing frame (2) and contains a soft air cushion (6), an air pressure valve (3) and a rotary table (4) are arranged at the other end of the rhombohedral fixing frame (2) in sequence, and the rotary table (4) is provided with a concave face (5). According to the stopper, by means of a rotation air pressure inflation structure, the waterproof, dustproof and disengaging-preventing functions are achieved, and comfort is enhanced when a user wears the stopper.

Description

A kind of stopper

Technical field

The present invention relates to a kind of stopper, especially for the plug structure of people's ear.

Background technology

Earplug, small-sized receiver, can fill in ear, is commonly used on radio and sonifer, also can as the stopper of plug in ear, is used for anti-sealing to enter in ear during swimming, can also be used to reducing noise interference, i.e. noiseproof earplug, Sleep earplug etc.Labour protection type noiseproof earplug generally steeps mould material by silica gel or low pressure, high resiliency polyester material is made.With external auditory meatus close contact after insertion auditory meatus, enter middle ear and internal ear (eardrum) with isolated sound, reach the object of sound insulation, thus protection workman audition.

The tympanum that the sound that labour protection type noiseproof earplug can prevent machine from sending causes is uncomfortable, and noiseproof feature is good, but harder, has worn obvious distending pain sense, is not suitable for sleep and uses.The earplug of general labour protection is all with rope, conveniently extracts at any time.

Earplug is improving water flood, concentrate on, travel and go on business, protect audition etc.Be you at home, bedroom, review one's lessons by oneself the good assistant of the places such as classroom, by bus ship airline traveling, factory, construction site, bustling urban district from noise jamming.

Summary of the invention

The technical problem to be solved in the present invention is: provide a kind of stopper, realizes water proof and dust proof anti-drop function, can also strengthen comfort.

The technical solution used in the present invention is: a kind of stopper, comprises hemisphere cushion, and one end of hemisphere cushion is connected with Pedicellus et Pericarpium Trapae limit fixed mount, fluting is had in the middle of the fixed mount of Pedicellus et Pericarpium Trapae limit, hold soft air cushion, the Pedicellus et Pericarpium Trapae limit fixed mount other end is followed successively by air pressure valve and rotating disk, and rotating disk is provided with concave surface.

Described stopper adopts a kind of rotary pneumatic laminated structure, and when afterbody rotates, in the middle part of stopper, air pressure increases, and can heave inner flexible air cushion, air cushion is heaved degree and can be controlled, and can meet the different canal sizes of different users, sensation is closed and got well in a word.Owing to being that inside is heaved, ear hole or nostril can well being sealed and horizontal good fixing, owing to being flexible air cushion, hitting if receive larger strength, can not damage as conventional earplugs or stopper and use position.Be finished rear set direction, regaining air cushion can take out.This stopper not only limits to and earplug or waterproof sieve simultaneously, it may be used for electrical equipment jack anti-gray, such as mobile phone, notebook computer jack can use this stopper, practicality of the present invention is very extensive, such as wall punching is fixing adopts this stopper, not only arbitrarily can take out replacing, but also can reduce the damage to body of wall such as nail.

Accompanying drawing explanation

Fig. 1 is the schematic diagram of structure of the present invention;

Fig. 2 is Inflatable rotary schematic diagram of the present invention.

Detailed description of the invention

As depicted in figs. 1 and 2, stopper comprises hemisphere cushion 1, hemisphere cushion 1 is connected with Pedicellus et Pericarpium Trapae limit fixed mount 2, fluting is had in the middle of the fixed mount 2 of Pedicellus et Pericarpium Trapae limit, hold soft air cushion 6, Pedicellus et Pericarpium Trapae limit fixed mount 2 other end is connected with air pressure valve 3 and rotating disk 4 successively, and air pressure valve 3 and rotating disk 4 are worked in coordination and realized air pressure change, concave surface 5 design on rotating disk 4 facilitates staff to rotate, and increases frictional force.

Claims

1. a stopper, it is characterized in that: comprise hemisphere cushion (1), one end of hemisphere cushion (1) is connected with Pedicellus et Pericarpium Trapae limit fixed mount (2), fluting is had in the middle of Pedicellus et Pericarpium Trapae limit fixed mount (2), hold soft air cushion (6), Pedicellus et Pericarpium Trapae limit fixed mount (2) other end is followed successively by air pressure valve (3) and rotating disk (4), rotating disk (4) is provided with concave surface (5).
