Embodiment
Below by embodiment, and in conjunction with the accompanying drawings, technical scheme of the present invention is described in further detail.
Embodiment:
As the ear microphone of Fig. 1 to scalable clamping power shown in Figure 7, left and right earphone 10 is arranged, the left and right connecting rod 4 that links to each other with left and right earphone, the end of connecting rod 4 is fixed with bearing pin 42, the length of bearing pin slightly is longer than connecting rod 4 width, and connecting rod has the slotted eye 41 of radial arrangement near leading section.In the end of left and right connecting rod 4 connecting rod holder 6 is arranged, see shown in Figure 4ly, Fig. 4 a is connecting rod holder 6 stereograms, and Fig. 4 b is a front view.The left and right two ends of connecting rod holder are provided with bearing pin 42 and match, also can make the left and right connecting rod that links to each other with bearing pin to make the cotter-pin hold 61 that to a certain degree rotates, the extent of opening of pin-and-hole is less than the pin-and-hole diameter, and can make that the left and right connecting rod that links to each other with bearing pin rotates along with the rotation of bearing pin may.The screw 63 of connection is arranged above the connecting rod holder, and a side of holder is equipped with fixed cap 7, sees shown in Figure 6.Have on the fixed cap and corresponding two circular holes 72 of cotter-pin hold, the end that is used for bearing pin is passed through, and periphery has four aperture 71 is installed, and aperture and four cylinders, the 62 corresponding and tight fits that protrude from the holder side are installed.Support 2 is arranged on connecting rod holder 6, see shown in Figure 3ly, Fig. 3 a is a stereogram, and Fig. 3 b is a front view.The end face of support porose 22, be used to install adjusting screw(rod) 1, two ends have opposed anteroposterior four connecting holes 21, connecting hole matches with slotted eye 41 on the left and right connecting rod, be connected with latch 8 between connecting hole and the slotted eye, the connecting hole 21 on the end of latch and the support 2 is close-fitting mutually.The end of adjusting screw(rod) 1 is provided with regulating handle, and screw rod is provided with upper and lower two cannelures 11,12, (see figure 7) and the slotted collar 3 that cooperates with cannelure.
During installation, earlier the bearing pin 42 of left connecting rod 4 ends that link to each other with left earphone is inserted in the cotter-pin hold 61 on connecting rod holders 6 left sides, the bearing pin 42 of right connecting rod end is inserted in the cotter-pin hold 61 on connecting rod holder 6 right sides, and the edge of connecting rod is contacted with the block face 64 of connecting rod holder, fixed cap 7 is covered a side of connecting rod holder opening, four holes 71 on the fixed cap and four cylinders, the 62 corresponding and tight fits of connecting rod holder side.Again adjusting screw(rod) 1 is penetrated the hole 22 on the support 2, and slotted collar 3 snapped in adjusting screw(rod) top, is positioned at the cannelure 11 at support 2 back sides, screw rod is screwed in connection screw 63 on the connecting rod holder 6, slotted collar 3 is snapped in the draw-in groove 12 that is positioned at connection screw 63 back sides, screw rod bottom, latch 8 is passed the connecting hole 21 on support 2 left sides and the slotted eye 41 on the left connecting rod 4 respectively, latch 8 terminal and connecting hole 21 close-fittings; Again latch 8 is passed the connecting hole 21 on support 2 the right and the elliptical aperture 41 on the right connecting rod 4 respectively, latch 8 terminal and connecting hole 21 close-fittings can use.
In use too tightly need to amplify, only need adjusting screw(rod) 1 is rotated counterclockwise as the ear clamping; If feel too pine, then adjusting screw(rod) turns clockwise, and two earphones can inwardly shrink.
