[0026] Reference Figure 1As shown, the utility model provides a technical solution: an earphone with a double-flip earphone box, comprising an earphone box body 1, earphones are placed in the earphone box body 1, a charging hole is opened on the surface of the earphone box body 1, and fixing devices 2 are provided on both sides of the earphone box body 1. By providing the fixing device 2, the protective cover 206 is fixed, and it is avoided that when the staff puts the earphone box body 1 in a pocket or a backpack, the protective cover 206 is hit and passively opened due to the large-scale movement of the staff, causing the earphone to detach from the earphone box body 1, thereby improving the stability of the equipment. A dustproof device 3 is provided on the surface of the earphone box body 1. By providing the dustproof device 3, the charging hole of the earphone box body 1 is dustproof, and dust and impurities are avoided from entering the charging hole of the earphone box body 1, resulting in affecting the charging effect of the earphone, thereby improving the practicality of the device.

[0027] The specific arrangement and function of the fixing device 2 and the dustproof device 3 are described in detail below.

[0028] Reference Figure 2 and Figure 3As shown, in this embodiment: the fixing device 2 includes two fixing blocks 201, the two fixing blocks 201 are fixedly connected to the two sides of the earphone box body 1 respectively, a rotating rod 202 is fixedly connected inside the fixing block 201, both ends of the rotating rod 202 are rotatably connected to strip plates 203, a connecting block 205 is fixedly connected to the side where the two strip plates 203 are close to each other, a protective cover 206 is fixedly connected to one side of the connecting block 205, the protective cover 206 is slidably connected to the surface of the earphone box body 1, two fixing rods 207 are fixedly connected to the surface of the earphone box body 1, and an operating panel is slidably connected to the arc surface of the fixing rod 207 208, the side of the operation panel 208 close to the earphone box body 1 is fixedly connected with an insertion rod 209, the surface of the protective cover 206 is provided with a slot, and the end of the fixed rod 207 away from the earphone box body 1 is fixedly connected with a limiting plate 210, and the size of the insertion rod 209 is adapted to the size of the slot of the protective cover 206. When the staff pulls the operation panel 208, the operation panel 208 slides on the arc surface of the fixed rod 207. At this time, the limiting plate 210 has the effect of limiting the maximum sliding distance of the operation panel 208 on the fixed rod 207, thereby avoiding the staff from pulling the operation panel 208 due to excessive pulling force, resulting in the operation panel 208 sliding. The plate 208 is detached from the fixed rod 207. The arc surface of the fixed rod 207 is covered with a first spring 211. The two ends of the first spring 211 are fixedly connected to the operating plate 208 and the earphone box body 1 respectively. When the staff releases the operating plate 208, the rebound force of the first spring 211 drives the operating plate 208 to slide on the arc surface of the fixed rod 207. At the same time, the operating plate 208 drives the insertion rod 209 to move until the insertion rod 209 is inserted into the slot of the protective cover 206. At this time, the first spring 211 improves the stability of the insertion rod 209 when limiting the protective cover 206. There are two torsion springs 204, and the two ends of the torsion spring 204 are fixedly connected to the strip plate 203 and the fixed block 201 respectively. When the staff releases the limit of the protective cover 206 by the insertion rod 209, the torsion force of the torsion spring 204 drives the strip plate 203 to rotate on the rotating rod 202, and at the same time the strip plate 203 drives the connecting block 205 to move, and the connecting block 205 drives the protective cover 206 to move until the protective cover 206 is rotated and detached from the earphone box body 1. At this time, the torsion spring 204 achieves the effect of automatically opening the protective cover 206, so as to reduce the staff's operating steps on the device, thereby improving the staff's work efficiency.

[0029] Reference Figure 4As shown, specifically, the dustproof device 3 includes a fixing plate 31, the fixing plate 31 is fixedly connected to the surface of the earphone box body 1, a screw 32 is inserted into the inner thread of the fixing plate 31, one end of the screw 32 is rotatably connected to a connecting block 33, a sliding groove is provided on the surface of the earphone box body 1, and a protective plate 34 is slidably connected to the inner surface of the sliding groove of the earphone box body 1, and a connecting plate 35 is fixedly connected to the side of the protective plate 34 away from the earphone box body 1, and a connecting hole is provided on the surface of the connecting plate 35, and a positioning rod 36 is fixedly connected to the side of the connecting block 33 close to the screw 32, and the positioning rod 3 The arc surface of 6 is slidably connected to the fixed plate 31. When the staff rotates the screw rod 32, the screw rod 32 rotates in the threaded part of the fixed plate 31. At the same time, the screw rod 32 drives the connecting block 33 to move, and the connecting block 33 drives the positioning rod 36 to slide in the fixed plate 31. At this time, the positioning rod 36 has the effect of limiting the connection block 33 to rotate with the screw rod 32, thereby preventing the connection block 33 from rotating with the screw 32 when the staff rotates the screw 32, resulting in the connection block 33 being difficult to quickly insert into the connection hole of the connecting plate 35, causing the situation that affects the work of the staff.

[0030] Working principle: when the staff needs to fix the position of the protective cover 206, they press the protective cover 206, and the protective cover 206 drives the connecting block 205 to move, and the connecting block 205 drives the strip plate 203 to rotate on the rotating rod 202 until the protective cover 206 fits the surface of the earphone box body 1, and the protective cover 206 protects the earphones in the earphone box body 1. At this time, the operating panel 208 is released, and the rebound force of the first spring 211 drives the operating panel 208 to slide on the arc surface of the fixing rod 207. At the same time, the operating panel 208 drives the insertion rod 209 to move until the insertion rod 209 is inserted into the slot of the protective cover 206. At this time, the protective cover 206 is fixed, which avoids the situation that when the staff puts the earphone box body 1 in a pocket or backpack, the protective cover 206 is hit and passively opened due to the large movement of the staff, causing the earphones to detach from the earphone box body 1, thereby improving the stability of the equipment.

[0031] When the staff needs to protect the charging hole of the earphone box body 1, they pull the connecting plate 35, and the connecting plate 35 drives the protective plate 34 to slide in the sliding groove of the earphone box body 1 until the protective plate 34 completely blocks the charging hole of the earphone box body 1. At this time, the screw 32 is rotated, and the screw 32 rotates in the thread of the fixing plate 31. At the same time, the screw 32 drives the connecting block 33 to move, and the connecting block 33 drives the positioning rod 36 to slide in the fixing plate 31 until the connecting block 33 is inserted into the connecting hole of the connecting plate 35. At this time, the charging hole of the earphone box body 1 is dust-proof, and dust and impurities are prevented from entering the charging hole of the earphone box body 1, which affects the charging effect of the earphone, thereby improving the practicability of the device.
