The following describes the limiting mechanism and the headset according to the embodiments of the present invention in detail with reference to the accompanying drawings.

Referring to fig. 1 and 2, the limiting mechanism provided by the present invention includes an arc-shaped connecting member 10, two adjusting arms 20 and two brackets 30, wherein two ends of the arc-shaped connecting member 10 are provided with limiting portions 11; the two adjusting arms 20 are respectively telescopically sleeved on the limiting part 11 and can be locked and limited by the limiting part 11; the two brackets 30 are provided with earphones 40, and the two brackets 30 are respectively rotatably connected with the two adjusting arms 20 for driving the earphones 40 to rotate for limiting.

Wherein, arc connecting piece 10 and regulating arm 20 can adopt the rigid plastic material to make, support 30 can adopt rubber to make, and adjust the back to two regulating arms 20, when two regulating arms 20 are promoted by the application of force towards arc connecting piece 10 direction, earphone 40 can be driven and draw close each other, when two regulating arms 20 orientation deviate from arc connecting piece 10 direction and are promoted by the application of force, earphone 40 can be driven and keep away from each other, can adapt to different people's head from this, it is more diversified to be suitable for the scene, carry out the restriction removal to regulating arm 20 through spacing portion 11, make difficult pine take off when wearing, stability is better.

The utility model provides a stop gear is through establishing headphone 40 on two supports 30 to can drive headphone 40 through support 30 and rotate, when the enclosure of adjusting headphone 40 needs closes the size, can stretch out and draw back the regulation through two regulating arms 20 and arc connecting piece 10, and can carry out spacingly through spacing 11 to regulating arm 20, so, make headphone 40 stability better when wearing, can be suitable for more different application scenes.

Referring to fig. 1 and 3, the end of the limiting portion 11 is provided with a first protrusion 111, and the first protrusion 111 protrudes toward the inner side of the adjusting arm 20 to abut against the adjusting arm 20. The first protrusion 111 protrudes outward from the limiting portion 11 and can abut against the inner side of the adjusting arm 20, so that the limiting portion 11 and the adjusting arm 20 can be locked in a limiting manner, and stability of each other can be improved.

Furthermore, a plurality of limiting protrusions 21 are disposed on the inner side of the adjusting arm 20, and the limiting protrusions 21 are sequentially disposed along the length direction of the adjusting arm 20 and abut against the first protrusion 111 to limit the position of the first protrusion 111.

In this embodiment, the limiting protrusion 21 and the first protrusion 111 may abut against each other, so that when the adjusting arm 20 is not pushed by a force, the first protrusion 111 may be limited by the limiting protrusion 21 to move, and when the adjusting arm 20 is pushed by a force, the first protrusion 111 and the limiting protrusion 21 form a relative movement, thereby completing the position adjustment of the adjusting arm 20, and making the position adjustment of the headphone 40 simpler and more convenient.

It can be understood that the plurality of limiting protrusions 21 are configured into a plurality of arc-shaped grooves 22 arranged in sequence, the first protrusion 111 is suitable for being embedded in the arc-shaped grooves 22 to be limited by the arc-shaped grooves 22 to move, when the adjusting arm 20 is pushed, the first protrusion 111 moves relative to the plurality of limiting protrusions 21 and moves to different arc-shaped grooves 22 in sequence, and then is limited by the limiting protrusions 21 to move in the arc-shaped grooves 22, and therefore, the stability after overall adjustment is improved.

Referring to fig. 3 and 4, one end of the adjusting arm 20 has an opening 23, the limiting portion 11 extends into the adjusting arm 20 from the opening 23, the other end of the adjusting arm 20 has a pivoting portion 24, and the bracket 30 is pivoted to the pivoting portion 24; wherein, when promoting the regulating arm 20, spacing portion 11 can via uncovered 23 retract in the regulating arm 20 or stretch out outside the regulating arm 20, accomplish the position control to earphone 40 from this to, when needs are folded up, can adjust to minimum position through regulating arm 20, and through rotating support 30, from this, can make whole occupation space littleer after folding up, it is more convenient to fold up.

Specifically, the bracket 30 includes an arc portion 31 and a socket portion 32, and the arc portion 31 is adapted to be pivotally connected to the earphone 40; the engaging portion 32 is provided on the arc portion 31 and engaged with the pivot portion 24. The earphone receiver 40 and the arc-shaped portion 31 may be pivotable in a horizontal direction, and the sleeve portion 32 and the pivot portion 24 may be pivotable in a vertical direction, so that when folding is required, the earphone receiver 40 and the arc-shaped portion 31 are pivoted relatively, and then the support 30 and the pivot portion 24 are pivoted relatively, so that the rotation is simpler and more convenient.

Further, the inner peripheral wall of the sleeve joint part 32 is provided with a second bump 33, the peripheral wall of the pivot joint part 24 is provided with a blocking part 25, the second bump 33 and the blocking part 25 are positioned on the same horizontal plane, and when the sleeve joint part 32 and the pivot joint part 24 rotate mutually, the second bump 33 and the blocking part 25 form damping spacing mutually. Wherein, when rotating support 30, it is spacing through forming the damping between second lug 33 and the stop part 25, can be so that earphone 40 is difficult for the gyration after rotating, can adjust to suitable position, and stability is better to, when support 30 adopted the rubber material, can be so that the damping effect is better.

Referring to fig. 1, the outer side of the stopper portion 11 has a plurality of numeral marks 112, and the plurality of numeral marks 112 are provided at intervals along the longitudinal direction of the stopper portion 11. The number mark 112 can be used to indicate the adjustment position of the earphone 40, so that the user can adjust the position to a proper position for wearing when using, and the use is more convenient.

Optionally, the inner side of the arc-shaped connecting member 10 is provided with an arc-shaped supporting pad 12, and the arc-shaped supporting pad 12 extends along the length direction of the arc-shaped connecting member 10. Wherein, can support and lean on at user's head through arc supporting pad 12 for user's head can not form the buffering with arc connecting piece 10 direct contact, through arc supporting pad 12, makes to wear the back comfort level higher.

Referring to fig. 5, a headphone provided in an embodiment of the present invention includes the above-mentioned limiting mechanism. Wherein, the limiting mechanism is installed on the headset, so that the headset can adjust the position of the earphone receiver 40 through the limiting mechanism, and the technical effects and technical schemes are consistent with the above and are not repeated one by one.
