Abstract

The invention discloses a retractable earphone wire storage box, comprising an upper top cover assembly (1), a lower chassis assembly (2), an earphone wire (3) and a round sticking tape wool surface (4), wherein the upper top cover assembly (1) is sleeved on the lower chassis assembly (2), positioning protrusions (2-1-5) are respectively clamped into positioning grooves (1-1-4) to realize the relative rotation and limiting of the upper top cover assembly (1) and the lower chassis assembly (2), reset is realized through a central torsional spring (1-3), and reset of the earphone wire (3-2) is realized through uniformly-distributed torsional springs (2-2). The retractable earphone wire storage box disclosed by the invention not only can realize automatic storage, but also can be pulled to any length for use, and moreover, the earphone wire on one side can be pulled separately, and a user can directly hang the storage box in front of the chest to use an earphone; and the retractable earphone wire storage box has the advantages of high practicability, simple structure, convenient operation, reliable use and high applicability.

Description

technical field [0001] The invention relates to a storage device, in particular to an earphone wire storage device with a telescopic function. Background technique [0002] At present, with the popularity of mobile phones, the accessories used with mobile phones, such as earphones, are the standard equipment for mobile phone users. After using the wired earphones, users often put the earphones at hand. Because the earphone wires are thin and long, they are easily entangled. , It is difficult to sort out, which brings great inconvenience to the user for the next use. In addition, the earphones placed at hand are easy to be worn and squeezed by other objects without the protection of any device, which will affect the appearance of the earphones. In severe cases, it will also affect the normal use of the earphones. Although there are some earphone storage bags, But it is simply accommodated in it, and it will still be messy and entangled, and it is too large to be portable. ...
