Description

Head-wearing earphone rotation limiting mechanism

Technical Field

The utility model relates to the technical field of earphones, in particular to a rotation limiting mechanism of a headset.

Background

The earphone is a pair of conversion units which receive the electric signals from the media player or receiver and convert them into audible sound waves by using a speaker near the ear. The earphone can be separated from the media player, can be connected by only using one plug, and can listen to the sound independently without influencing other people; can also isolate the sound of the surrounding environment, and is very helpful for people who use in a noisy environment such as a recording studio, a bar, a trip, sports, and the like.

The structure of traditional headphone includes the bandeau and sets up the earlap at bandeau both ends, installs the sound production original paper in the earlap. However, in the existing headset, the earmuffs of the headset can only do telescopic movement and cannot rotate, so that the headset cannot be suitable for being worn by consumers with different head sizes, is uncomfortable to wear, and affects the experience of the consumers.

SUMMERY OF THE UTILITY MODEL

The utility model aims to provide a rotation limiting mechanism of a headset, aiming at the defects in the prior art.

The purpose of the utility model is realized by the following technical scheme:

the rotation limiting mechanism of the headset comprises a head band, a hinge post and an earshell, wherein the end part of the head band is hinged with the top end of the hinge post; the bottom of hinge post is seted up with stopper complex spacing groove.

Wherein, the spacing groove is circular arc structure.

Wherein, the end face of the limiting block close to the limiting groove is a circular arc face.

Wherein, the arc opening has been seted up to the periphery side of erection column, and articulated support still is equipped with articulated seat, and spacing block forms in the side of articulated seat, and articulated seat detachably installs at the lateral part of erection column, and under the assembled state, the stopper inserts in the arc opening.

Wherein, the hinged seat is fixedly connected with the hinged support through a screw.

The utility model has the beneficial effects that:

compared with the prior art, the headset rotation limiting mechanism has the advantages that the relative rotation between the head band and the earmuffs is realized through the hinge columns and the hinge supports, and the rotation range of the earmuffs relative to the head band can be limited through the matching of the limiting grooves and the limiting blocks, so that the damage of the earmuffs caused by excessive rotation is avoided, and the service life of the headset is prolonged.

Drawings

The utility model is further illustrated by means of the attached drawings, but the embodiments in the drawings do not constitute any limitation to the utility model, and for a person skilled in the art, other drawings can be obtained on the basis of the following drawings without inventive effort.

Reference numerals: the headband comprises a headband body 1, an earshell 2, a hinge column 3, a limiting groove 31, a hinge support 4, a mounting column 41, a hinge hole 42, a hinge seat 5 and a limiting block 51.

Detailed Description

The utility model is further described with reference to the following examples.

The embodiment of the rotation limiting mechanism of the headset comprises a head band 1, a hinge post 3 and an earshell 2, wherein the end part of the head band 1 is hinged with the top end of the hinge post 3, the limiting mechanism further comprises a hinge support 4, the hinge support 4 is of an arc structure, two ends of the hinge support 4 are hinged with the earshell 2, the middle part of the hinge support 4 extends upwards to form a mounting post 41, the mounting post 41 is provided with a hinge hole 42, a limiting block 51 radially inserted from the hinge hole 42 is arranged in the hinge hole 42, and the bottom end of the hinge post 3 is inserted into the hinge hole 42 of the mounting post 41 and is hinged with the mounting post 41; the bottom of the hinge column 3 is provided with a limiting groove 31 matched with the limiting block 51.

Compared with the prior art, but realize relative rotation through articulated post 3 and articulated mounting 4 between bandeau 1 and the conch 2, through spacing groove 31 and stopper 51's cooperation, can inject the rotation range of conch 2 for bandeau 1 to avoid conch 2 to lead to the fact destruction because of excessive rotation, prolong the life of earphone.

In the present embodiment, the limiting groove 31 has an arc-shaped structure. The arc-shaped structure can effectively limit the rotation range of the earmuff 2, and the rotation range is correspondingly set through the radius of the arc-shaped structure.

In this embodiment, the end surface of the stopper 51 close to the stopper groove 31 is a circular arc surface. The arc surface can be better with the 3 phase-matchs of hinge post, guarantees pivoted fluency.

In this embodiment, the arc opening has been seted up to the periphery side of erection column 41, and articulated support 4 still is equipped with articulated seat 5, and stopper 51 forms in the side of articulated seat 5, and articulated seat 5 detachably installs the lateral part at erection column 41, and under the assembled state, stopper 51 inserts in the arc opening.

In this embodiment, the hinge base 5 is fixedly connected with the hinge bracket 4 through screws, so that the connection is reliable, and the disassembly and assembly are convenient and rapid.

Finally, it should be noted that the above embodiments are only used for illustrating the technical solutions of the present invention, and not for limiting the protection scope of the present invention, although the present invention is described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that modifications or equivalent substitutions can be made on the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention.
