In order to realize the purpose, the utility model adopts the following technical scheme:

designing a USB extension line, which comprises a joint and a USB connection wire, wherein the USB connection wire is connected with the joint, a connecting block is arranged between the joint and the USB connection wire, one end of the USB connection wire penetrates through the connecting block and extends to the other side of the connecting block, a circular groove is formed in the middle of one side, close to the joint, of the connecting block, the joint extends to the inner side of the circular groove, and a connecting structure is arranged between the outer part of the joint and the inner side of the circular groove;

connection structure includes arc piece and ring channel, the ring channel is seted up the outside of connecting, the arc piece is connected the inboard of circular recess, a plurality of the arc piece slides and sets up the inboard of circular recess, and the size of arc piece matches each other with the size line of circular recess.

Preferably, the diameter of the coupling and the diameter of the inner side of the circular groove are matched with each other, and the outer surface of the coupling and the inner surface of the circular groove are in contact with each other.

Preferably, the rubber sleeve is sleeved at the external connection position of the connecting block and the USB connecting wire.

Preferably, the inner side of the connecting block is matched with the USB connecting wire.

The utility model provides a USB extension line, beneficial effect lies in: the USB extension line protects the joint between the joint of the USB data line and the connection line, and prevents the outer protective skin of the data line from being broken due to bending and abrasion in the using process of the joint of the USB data line and the connection line.

Fig. 3 is an enlarged view of a portion a of the USB extension cord shown in fig. 1.

In the figure: connecting block 1, connect 2, connection structure 3, arc piece 31, ring channel 32, rubber sleeve 4, USB wiring 5, circular groove 6.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments.

Example 1

Referring to fig. 1-3, a USB extension cord, including a connector 2 and a USB connection wire 5, and the USB connection wire 5 is connected to the connector 2, a connection block 1 is disposed between the connector 2 and the USB connection wire 5, and one end of the USB connection wire 5 penetrates the connection block 1 and extends to the other side of the connection block 1, a circular groove 6 is disposed in the middle of one side of the connection block 1 close to the connector 2, and the connector 2 extends to the inner side of the circular groove 6, the diameter of the connector 2 matches the diameter of the inner side of the circular groove 6, and the outer surface of the connector 2 contacts the inner surface of the circular groove 6, the extension cord of the USB achieves extension of the connection length by the terminal connection of the data wire, by fixedly disposing the connection block 1 at the connection of the connector 2 and the USB connection wire 5, the diameter of one end of the connector 1 matches the diameter of the USB connection wire 5, the connection portion between the connector 2 and the USB connection wire 5 of the USB data wire can be protected, and the outer protection skin of the data wire is prevented from being broken due to bending and abrasion during use, the rubber sleeve 4 has a certain elasticity, and the connection portion between the connection block 1 and the USB connection wire 5 is further protected.

The inner side of the connecting block 1 is matched with the USB connecting wire 5, and a connecting structure 3 is arranged between the outer part of the joint 2 and the inner side of the circular groove 6; connection structure 3 includes arc piece 31 and ring channel 32, the outside at joint 2 is seted up to ring channel 32, arc piece 31 is connected in the inboard of circular recess 6, a plurality of arc piece 31 slides and sets up in the inboard of circular recess 6, and the size of arc piece 31 is gone with the size of circular recess 6 and is matchd each other, when certain angle's rotation appears in USB wiring 5, appear rotating relatively between joint 2 and USB wiring 5 and outside connecting block 1, synchronous rotation prevents to appear, cause the problem of tearing to appear.
