Detailed Description
Example 1
As shown in fig. 1 to 5, the technical solution of the ventilating ear muff for earphone of the present invention is that it comprises an outer coating layer 1, characterized in that: the periphery of outer cladding layer 1 leans on lower position fixedly connected with solid fixed ring 3, gu fixed ring 3 upper portion fixedly connected with buckle head 301, the clearance buckle is connected with rotatory adjusting ring 2 on buckle head 301, rotatory adjusting ring 2 can rotate on gu fixed ring 3, gu fixed ring 3 side equidistance evenly is seted up six holes and wherein interference fit installs bearing 7, interference fit installs transmission shaft 5 in the bearing 7 inner circle, transmission shaft 5 one end is located gu fixed ring 3 cavity groove and fixedly connected with gear 501, the other end is screw rod 502 and passes outer cladding layer 1 and stretch into in outer cladding layer 1 inner chamber, gear 501 with rotatory adjusting ring 2 tooth fit installs, screw thread fit installs two stripper plates 6 on the screw rod 502, the inside cladding of outer cladding layer 1 is equipped with six the same sponge cores 4, the screw 502 on the drive shaft 5 extends into the sponge core 4 and the pressing plate 6 is embedded in the sponge core 4.
The outer coating layer 1 is made of breathable cloth and is circular, and a tensioning fixing belt is arranged at the lower part of the outer coating layer, so that the outer coating layer can be conveniently sleeved on an earphone.
The lower surface of the adjusting ring 2 is provided with a gear ring 201, the inner side surface is provided with a fastening groove 202, the gear ring 201 is engaged and matched with the gear 501, and the fastening groove 202 is fastened and connected with the fastening head 301.
