To be oriented to for the rotation of shaft 5.
Adapt to bulb 51 is spherical limiting slot 81, and adapt to limit shaft 52 is linear type limiting slot 82, linear type
82 bottom of limiting slot is limit inclined-plane 83, exactly inclined when the end of limit shaft 52 goes to the position.
In the present embodiment, sliding support includes external splint 1, inner splint 9 and trim 2, and external splint 1, inner splint 9 are distinguished
Positioned at the outside and inside of headband 3, by screw association, trim 2 passes through clamping group with inner splint 9 for external splint 1, inner splint 9
It closes, rotary shaft base 8 is located in trim 2, and rotary shaft base 8 is connected and fixed with inner splint 9 by the second screw 10.
As shown in fig. 6, there are three mounting holes for setting on three angles of rotary shaft base 8, three second screws 10 can be installed,
Lack an angle, is the third threading hole avoided in ear packet rear shell 7 in fact in this position.
Second screw 10 can also play the role of combining external splint 1, inner splint 9 simultaneously, thus eliminate one group of spiral shell
Nail.
As shown in Figure 1 and Figure 2, it is provided with the bulb 51 that locating piece pushes down shaft 5 on inner splint 9, bulb 51 is maintained at and is turned
In axis pedestal 8, the one side that locating piece 54 is contacted with bulb 51 is the dome shape of indent.
External splint 1, inner splint 9 are set, and external splint 1 and inner splint 9 clamp headband 3, are for convenience by sliding support
It is installed on headband 3.
Guide pad can be set on external splint 1 and/or inner splint 9, the slide-and-guide in the guide rail of headband 3.Trim 2 can
To cover in rotary shaft base 8, improve the appearance at the position, appearance is allowed to become clean and tidy.
2 the upper side and lower side of trim is inclined-plane, and evacuation ear packet rear shell 7 rotates upwardly and downwardly process.It is arranged with this configuration,
Not only the covering effect of trim 2 oneself may be implemented, but also can be that ear packet reserves rotation space.
The upside of trim 2 is provided with the first threading hole 23 for introducing power cord and/or signal wire, trim 2 and ear packet
The adjacent side of rear shell 7 is provided with the second threading hole 22 for introducing power cord and/or signal wire, this is for the company between ear packet
Structure set by line, as shown in Figure 7.
As shown in figure 8, the side adjacent with ear packet rear shell 7 of trim 2 is provided with the second through-hole 21, shaft 5 passes through second
Through-hole 21 surrounds and is equipped with damping sponge 4 between 21 trim 2 of the second through-hole and ear packet rear shell 7.Damping sponge 4 can be fixed on
On trim 2, or be fixed in ear packet rear shell 7, be adhesively fixed, damping sponge 4 can to the rotating oscillation damping of ear packet,
Hard friction can occur to avoid ear packet rear shell 7 and trim 2.
As shown in Figure 1, Figure 2, shown in Fig. 7, one end that shaft 5 is connect with ear packet rear shell 7 is provided with axial threaded hole 53, shaft
5 are connected and fixed with ear packet rear shell 7 by third screw 6, and third screw 6 is provided with anti-skid structure.
Because the bulb end of shaft 5 is relatively large in diameter, the other end of shaft 5 needs the first through hole 84 across rotary shaft base 8,
So shaft 5 must be Detachable connection structure with ear packet rear shell 7.
Anti-skid screw may be used in third screw 6, and itself on band anti-skid structure, such as screw cap bottom surface with regard to carrying one
Circle protrusion, can prevent third screw 6 from being loosened from shaft 5 in this way.Third screw 6, which does anti-skidding processing, can improve 5 He of shaft
The stability of 7 connection structure of ear packet rear shell.
As shown in Figure 5, Figure 7, shaft 5 is threaded the one end in hole 53 and is provided with anti-rotation protrusion 55 and locating piece 54, anti-rotation
Protrusion 55 and locating piece 54 are also symmetrically arranged in shaft 5.
It is provided with locating slot 71 in ear packet rear shell 7, anti-spin slot 72 is set in locating slot 71, shaft 5 is threaded hole 53
One end is mounted in locating slot 71, and 71 bottom of locating slot is provided with third through-hole 73 and is passed through for third screw 6, as shown in Figure 3.
The structure of locating piece 54 and locating slot 71 can facilitate the connection of shaft 5 and Er Bao rear shells 7 to combine.
Anti- rotation protrusion 55 is set in shaft 5, anti-spin slot 72 is set in the locating slot 71 of ear packet rear shell 7, is tied by the anti-rotation
Structure can prevent from rotating between shaft 5 and Er Bao rear shells 7 in ear packet rotation process, after improving shaft 5 and Er Bao
The stability of 7 connection structure of shell.
Third threading hole is provided in ear packet rear shell 7 for introducing power cord and/or signal wire (third threading hole is not shown).
