Embodiment Construction

[0012] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0013] like figure 1 , image 3 , the structure of elastic earplug of the present invention is, comprises movable round head 1 and baffle plate 5, is connected with the elastic material body 2 of middle part bulge between movable round head 1 and baffle plate 5, and the two ends of elastic material body 2 are connected with movable respectively. The round head 1 and the baffle plate 5 are fixedly connected or bonded, and the elastic material body 2 has stretching function and elastic performance. The axis of the movable round head 1 is equipped with a movable tie rod 4, and the elastic material body 2 surrounds the movable tie rod 4. The pull rod 4 passes through the axis hole of the baffle plate 5 , and a handle 3 is arranged at the outer end of the axis hole of the movable pull rod 4 passing through the baffle plate 5 . Movable pull bar 4...

Abstract

The invention discloses an elastic earplug which comprises a movable round head and a baffle, wherein elastic material bodies with raised middle parts are connected between the movable round head and the baffle; a movable draw bar is installed at the axle center of the movable round head and penetrates through the hole in the axle center of the baffle; a handle is arranged at the external end, which penetrates through the hole in the axle center of the baffle, of the movable draw bar; and the maximum diameter of the middle part of an air bag is larger than the diameter of the external ear canal of the ordinary people. The elastic earplug has the following beneficial effects: the earplug has a reasonable structure, is tightly coupled with the ear canal so that the sound insulation and sealing effects are obvious, and has low manufacturing cost.

Description

technical field [0001] The invention belongs to the technical field of human body protection products and relates to elastic earplugs. Background technique [0002] In some workplaces, the ambient noise is extremely loud, which is unbearable for the human ear, and it is necessary to plug the ears to stay and do things in these occasions; sometimes when sleeping, other sounds in the room or outside the window are relatively loud and cannot be stopped, so the only way to stop is to plug in the earplugs. Sleep quietly; and when swimming, you need to plug tightly to prevent water from entering the ear canal and cause infection; there are other places where you need to plug your ears in time to prevent noise damage and protect the health of the staff. [0003] However, due to the unreasonable structure of the existing earplugs, the combination with the ear is not tight, the effect is not good after plugging, there is looseness and no sound insulation, and some also produce new no...
