Detailed Description

Please refer to fig. 1 to 5:

a hearing aid facilitating the replacement of an ear plug head, comprising;

organism 1 and earphone head 2, earphone head 2 is located below organism 1 right side, earphone head 2 front end is equipped with earplug head 3, the inboard butt joint groove 10 that has opened of earphone head 2 front end, butt joint groove 10 inside is equipped with snap ring 4, earplug head 3 meet in snap ring 4 front end, butt joint groove 10 inside and be located snap ring 4 rear end is equipped with two-way spring return pole 5, two-way spring return pole 5 left and right ends all is fixed with and is located the tensioning plate 8 of snap ring 4 inner wall, each tensioning plate 8 front end homogeneous phase has been connect stopper 9, every stopper 9 rear end all is equipped with and is located the clamp splice 13 of snap ring 4 inner wall, the organism 2 with have been connected sound guide 14 between earphone head 2, each tensioning plate 8 outer end homogeneous phase has been connected ejector pad 7, every tensioning plate 8 outer end just is located the rear end of snap ring 4 all is fixed with dog 11, a spring return rod 12 positioned on the inner side of the expansion plate 15 is connected between each clamping block 13 and the limiting block 9 adjacent to the front end;

specifically, set the initial state of two-way spring return bar 5 and spring release bar 12 to compression state, combine the resilience force of two-way spring return bar 5, tensioning plate 8 can be toward the inner wall of outer tensioning snap ring 4 this moment, and combine the resilience force of spring release bar 12, dog 11 can withstand the rear end of snap ring 4, and clamp splice 13 can support 4 inner wall rear ends of snap ring, thereby make the initial state of snap ring 4 carry out the front and back centre gripping spacing by clamp splice 13 and dog 11.

A convex block 6 is fixed at the outer end of each push block 7, and the outer end of each convex block 6 penetrates out of the outer end of the earphone head 2 in a sliding manner;

further, when the earplug head 3 is dismantled to needs, through pressing two lugs 6 simultaneously, lug 6 then drives

ejector pad

7 and 8 compression two-way spring return pole 5 of tensioning plate, until dog 11 and clamp splice 13 no longer centre gripping snap ring 4 after, extract snap ring 4 from butt joint groove 10 again, then be convenient for at this moment with earplug head 3 and the separation of earphone head 2, thereby be convenient for change the earplug head 3 of multiple size, do benefit to and promote the wearing comfort level of hearing impaired person, and be convenient for clear up the earwax on the earplug head 3, the normal listening effect of earplug head 3 has been guaranteed.

The outer side of the front end of each limiting block 9 is inclined, the outer side of the rear end of each clamping block 13 is inclined, and the outer end between each clamping block 13 and the limiting block 9 adjacent to the front end is connected with a telescopic plate 15;

further, when the earplug head 3 needs to be installed, the snap ring 4 is inserted into the butt joint groove 10, and meanwhile, the snap ring 4 pushes the tension plate 8 along the inclined surface of the limit block 9, when the two tension plates 8 approach each other, the two-way spring return rod 5 is compressed, the inner wall of the snap ring 4 slides backwards along the expansion plate 15 until the rear end of the snap ring 4 moves to the gap between the stop block 11 and the clamping block 13, the tension plate 8 is driven to move outwards by the resilience of the two-way spring return rod 5, the tension plate 8 outwards tensions the inner wall of the snap ring 4, meanwhile, the rear end of the snap ring 4 slides into the gap between the stop block 11 and the clamping block 13 along the inclined surface of the clamping block 13, the clamping block 13 compresses the spring return rod 12, and the expansion plate 15 contracts, the resilience of the spring return rod 12 drives the rear end of the inner wall of the clamping block 13 to abut against the rear end of the snap ring 4, and the stop block 11 abuts against the rear end of the snap ring 4, consequently combine dog 11 and clamp splice 13 to carry out the centre gripping spacingly around with snap ring 4 to prevent that snap ring 4 is not hard up in butt joint groove 10, in order to avoid earplug head 3 and earphone head 2 to separate, guaranteed the fastness after earplug head 3 installs, in order to avoid earplug head 3 and earphone head 2 to separate and the condition of losing takes place.
