Wherein:

11-box body, 12-key hole, 13-earphone slot, 14-snap fastener, 15-box cover, 16-earphone slot, 17-earphone positioning groove, 110-rotating hole, 111-limiting groove and 141-limiting step.

The specific implementation mode is as follows:

the present invention will be further described with reference to the accompanying drawings.

As fig. 1 to 4, the utility model relates to a key chain with function is accomodate to earphone, including box body 11, lid 15 and magnet, box body 11 and lid 15 are the triangle-shaped structure, and the outer wall of box body 11 is inwards sunken and forms earphone wire casing 16, is equipped with keyhole 12 and earphone slot 13 in earphone wire casing 16, and keyhole 12 is located a apex angle department of box body 11, is equipped with two earphone constant head tanks 17 on a side end face of box body 11, and earphone constant head tank 17 is linked together with earphone wire casing 16.

The two box covers 15 are symmetrically connected to the box body 11, and the two box covers 15 correspondingly cover the two earphone positioning grooves 17; magnet is arranged on the box body 11 and the box cover 15, and the box body 11 and the box cover 15 are attracted by the magnet. In order to facilitate the installation of the magnet, grooves are formed in the box body 11 and the box cover 15, and the magnet is correspondingly fixed in the grooves through glue (the structure of the magnet is not shown in fig. 1-4).

In the present invention, each box cover 15 is rotatably connected to the box body 11 through a snap fastener 14, and a rotation hole 110 is formed on the box body 11. The snap 14 is a T-shaped structure having a press cap and a rotating shaft, a limit step 141 is provided on the rotating shaft, a limit groove 111 is provided on the inner wall of the rotating hole 110, the rotating shaft of the snap 14 passes through the box cover 15 and extends into the rotating hole 110, and the limit step 141 is disposed in the limit groove 111. The stop step 141 cooperates with the stop groove 111 for axially positioning the snap 14 within the rotation hole 110.

In order to facilitate the press-fitting of the snap fastener 14 into the rotation hole 110 and the removal of the rotation hole 110, the upper and lower end surfaces of the limit step 141 are both inclined surfaces. Correspondingly, the upper and lower end walls of the rotation hole 110 are also of an inclined surface structure. The snap fastener 14 is made of a rubber material, and when the snap fastener 14 is pressed, the snap fastener 14 is elastically deformed and inserted into the rotation hole 110.

The three top angles of the box body 11 and the three top angles of the box cover 15 are arc transition surfaces. The circular arc transition surface avoids scratching skin on one hand, and delays bending of the earphone wire on the other hand, so that the earphone is protected.

The key hole 12 is positioned at the top of the whole regular triangle box body, which is convenient to be connected with the key of a user in series, the box cover 15 is divided into a left part and a right part, and the snap fasteners 14 are adopted to connect the box cover 15 and the box body 11, thereby achieving the purpose of rotating the box cover.

The earphone line slot 16 is provided with a space for winding the earphone line, the space is communicated with the earphone line slot at the top of the box body, and when the winding of the earphone line is finished, the earphone receiver can be placed in the earphone positioning slot 17 in the box body.

When the earphone is wound, the earphone interface can be firstly inserted into the slot 13, so that the problem of placing the earphone interface is solved, and the effect of fixing the earphone is achieved. The earphone positioning groove 17 is located in the box, and the earphone after winding is fixed in the positioning groove to avoid shaking.

At the beginning of winding the earphone, firstly inserting an earphone interface into an earphone slot 13 of the box body 11, winding an earphone wire along an earphone wire slot 16, wherein the shape of the box body 11 in the shape of a regular triangle is also convenient for placing an earphone, after winding is finished, placing an earphone receiver in an earphone positioning slot 17 in the box body 11 from the concave position at the top end of the box body 11, and inwards rotating a box cover 15 to seal the box body 11; the key string is arranged in the key hole 12, and the key chain is placed in a pocket or hung on a waist loop, so that the key is small in size and convenient to carry.

The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, several modifications can be made without departing from the principle of the present invention, and these modifications should also be regarded as the protection scope of the present invention.
