Abstract
The invention discloses an air bag type earplug which comprises a movable circular head and a baffle plate, wherein an air bag is connected between the movable circular head and the baffle plate; an axle center of the movable circular head is provided with a movable pull rod; the movable pull rod penetrates through an axle center hole of the baffle plate; the outer end of the movable pull rod penetrating through the axle center hole of the baffle plate is provided with a handle; and the maximal diameter of the middle of the air bag is larger than the external auditory canal diameter of a common person. The air bag type earplug has the advantages of reasonable structure, tight combination of the earplug and auditory meatus, obvious sound isolating and sealing effect and low manufacture cost.
Description
Technical field
The invention belongs to physical protection articles for use technical field, relate to a kind of gasbag-type earplug.
Background technology
Some workplace, the noise of environment is big especially, and people's ear is difficult to bear, and need clog ear could do things in these occasions stops; In bed, room or other sound are bigger outside window can't be prevented again, just has only earplug beyond the Great Wall, the sleep of could setting aside all worries sometimes; Also have when swimming, need jam-pack, anti-sealing gets into auditory meatus and causes infection; Some places that also have other need in time ear beyond the Great Wall, stop the injury of noise, and are healthy to protect the staff's.
But existing earplug because unreasonable structure, cause with ear combine not closely, the back effect is bad beyond the Great Wall, has loosening and not sound insulation, what have also can produce new noise, has influenced user of service's mood, does not play due effect.
Summary of the invention
The purpose of this invention is to provide a kind of gasbag-type earplug, what solved earplug of the prior art and ear combines not closely, has loosening and not sound insulation, packing less problem.
The technical scheme that the present invention adopted is; A kind of gasbag-type earplug; Comprise movable round end and baffle plate, be connected with air bag between movable round end and the baffle plate, the axle center of movable round end is equipped with active pull rod; Active pull rod passes the axle center hole of baffle plate, and the axle center hole external end head that passes baffle plate at active pull rod is provided with handle.
The invention has the beneficial effects as follows that rational in infrastructure, earplug combines with auditory meatus closely, sound insulation and significant sealing affection, cost of manufacture is low.
Description of drawings
Fig. 1 is the structural representation that earplug of the present invention uses;
Fig. 2 is the structural representation in the earplug user mode of the present invention.
Among the figure, 1. movable round end, 2. air bag, 3. handle, 4. active pull rod, 5. baffle plate.
The specific embodiment
Below in conjunction with the accompanying drawing and the specific embodiment the present invention is elaborated.
Like Fig. 1, the structure of gasbag-type earplug of the present invention is to comprise movable round end 1 and baffle plate 5; Be connected with air bag 2 between movable round end 1 and the baffle plate 5; The two ends of air bag 2 are fixedly connected with baffle plate 5 with movable round end 1 respectively or are bonding, and air bag 2 adopts plastic material to make, and has stretch function and elastic performance; The axle center of movable round end 1 is equipped with active pull rod 4; Air bag 2 is centered around around the active pull rod 4, and active pull rod 4 passes the axle center hole of baffle plate 5, and the axle center hole external end head that passes baffle plate 5 at active pull rod 4 is provided with handle 3.Active pull rod 4 can adopt hollow-core construction, alleviates total quality.
Among Fig. 1, the diameter of movable round end 1 is slightly less than ordinary people's ear canal diameter, and the middle part maximum gauge of air bag 2 when initial condition is greater than ordinary people's external auditory meatus diameter, and the diameter of baffle plate 5 is greater than ordinary people's external auditory canal opening diameter.
With reference to Fig. 2, earplug of the present invention catches handle 3 that active pull rod 4 is promoted to movable round end 1 one ends earlier in use; Because the distance between movable round end 1 and the baffle plate 5 is elongated, air bag 2 receives stretching and shrinks to internal diameter direction, at this moment; Movable round end 1 and air bag 2 are stretched among the auditory meatus, touch external auditory canal opening, again handle 3 is unclamped gently up to baffle plate 5; Air bag 2 recovers to original shape under the elastic reaction of plastic material, and middle part protuberance enlarged-diameter is with the auditory meatus jam-packed, and active pull rod 4 natures move to baffle plate 5 one ends and stretch out; Make whole earplug contact with auditory meatus closely, firmly can not become flexible, played the purpose that stops ambient noise.
When needs take off earplug, be pressed into handle 3 towards baffle plate 5, active pull rod 4 moves to movable round end 1 one ends, and air bag 2 stretches, the gabarit reduced, earplug just can easily take out from ear.
Claims (2)
