Description

Automatic wire earphone of rewinding earphone cord Technical Field The utility model relates to the field of wired headphones, in particular to a wired headphone capable of automatically rewinding a headphone cable. Background With the continuous development of society, people demand audio equipment increasingly diversified, and wired earphone plays an important role in daily life as a common audio output equipment, and is widely applied to scenes such as music listening, phone answering, learning, office work and the like by virtue of advantages of stable audio transmission, good tone quality performance, no need of charging and the like. The utility model discloses a Chinese utility patent CN213403426U, which discloses a wired earphone capable of automatically rewinding an earphone wire, comprising a rewinding bin, a spring, a buckle and an earphone, wherein the spring is arranged in an internal hollow installation cavity of the rewinding bin, the spring is provided with a limit switch, the buckle is arranged on the rewinding bin in a pressing way, the buckle and the limit switch are mutually buckled or loosened, the earphone comprises an earplug arranged at the head end of the earphone wire and a plug arranged at the tail end of the earphone wire, the earphone wire is wound in the rewinding bin through the spring, the head end of the earphone wire is fixed on the spring, and the earplug and the plug are respectively arranged at two sides of the rewinding bin. However, when the above patent is used, the spring is clamped by the buckle to fix the length of the earphone wire, and this fixing manner is not firm, so that in the daily use process, the spring cannot be stably kept in a fixed state due to the fact that the buckle is easily loosened due to the influence of factors such as external force pulling and vibration, the earphone wire may be suddenly retracted, the use experience is affected, damage to the earphone is also likely to be caused, and even accidental injury to a user is likely to be caused in some cases. Disclosure of utility model In view of the above, the utility model provides a wired earphone capable of automatically rewinding an earphone wire, which mainly solves the technical problems that the conventional wired earphone capable of automatically rewinding the earphone wire is not firm in fastening, and the earphone wire is easy to retract suddenly in the using process to influence the use and damage of the earphone. In order to achieve the aim, the utility model adopts the following technical scheme that the wired earphone of the automatic rewinding earphone wire comprises a protective shell, wherein an earphone body is fixedly arranged in the protective shell, a rotating shaft is movably arranged in the protective shell, the earphone body is fixedly arranged in the rotating shaft, the outer wall of the rotating shaft is fixedly connected with a turntable, a spring is fixedly connected with the outer wall of the rotating shaft and is positioned at the bottom of the rotating shaft, the outer wall of the spring is fixedly connected with the outer wall of the protective shell, and a locking component is arranged between the protective shell and the rotating shaft; the locking assembly comprises a ratchet wheel, a pawl and a spring, wherein the ratchet wheel is fixedly connected to the outer wall of the rotating shaft and located at the bottom of the spring, the pawl is movably mounted at the bottom of the inner wall of the protective shell, the ratchet wheel and the pawl are clamped with each other, and the spring is fixedly mounted between the protective shell and the pawl. Through adopting above-mentioned technical scheme, when pulling the earphone body and making the rotation axis rotate, the ratchet rotates along with the rotation axis, if needs fixed earphone cord length this moment, the pawl can block into the tooth's socket of ratchet under the effect of spring, prevents the rotation axis and reverses to fixed earphone cord realizes the stable locking to earphone cord rolling state. As further description of the technical scheme, the top of the rotating shaft is provided with a clamping groove, and the earphone body is fixedly arranged in the clamping groove. Through adopting above-mentioned technical scheme, the draw-in groove can be firmly fixed earphone body on the rotation axis. As further description of the technical scheme, the protective cover is arranged on the top of the protective shell in a threaded manner, the transparent acrylic plate is fixedly arranged on the top of the protective cover, and anti-skid patterns are formed on the outer wall of the protective cover. Through adopting above-mentioned technical scheme, the visor can protect the inside part of protective housing, and transparent acrylic board conveniently observes inner structure, and the friction force when antiskid line then has increased handheld visor is convenient for install and dismantle the visor.
