[0020] The utility model is described in further detail below in conjunction with the accompanying drawings.

[0021] As attached Figure 1-5 The USB converter with a pull ring structure shown in the figure includes a converter body 1, the converter body 1 is provided with a USB interface 5, the converter body 1 is provided with a reversible pull ring 2, the pull ring 2 is provided with a hinge shaft 2.1, and the converter body 1 is provided with a shaft hole 1.2 matched with the hinge shaft, and the shaft hole 1.2 can be a waist-shaped hole. The end of the hinge shaft extending into the converter body 1 through the shaft hole is provided with an anti-slip component 3, and the converter body 1 is detachably provided with a limit block 4 for blocking a part of the shaft hole 1.2, and the limit block 4 cooperates with the shaft hole to limit the hinge shaft 2.1 from sliding along the shaft hole 1.2. Through the above-mentioned hinged pull ring 2 and converter body 1, it is convenient for users to use the pull ring to unplug the converter body 1 from the socket, thereby improving the convenience of use. The anti-slip component 3 provided at the same time can prevent the pull ring 2 from falling off from the converter body 1. In order to further improve the matching reliability between the pull ring 2 and the converter body 1, the hinge shaft is limited by a limit block 4 to prevent the hinge shaft from sliding along the rotating shaft hole, causing the anti-slip member 3 to fall out of the rotating shaft hole 1.2.

[0022] The anti-dropout member 3 and the hinge shaft 2.1 are located in the same plane and are L-shaped. The anti-dropout member and the hinge shaft located in the same plane and L-shaped can facilitate the insertion of the anti-dropout member from the shaft hole 1.2 into the converter body 1, thereby improving assembly efficiency.

[0023] The limit block 4 of the present design is provided with a blocking portion 4.1 opposite to the rotating shaft hole 1.2. The blocking portion is close to the anti-slip member 3 and is used to limit the axial movement of the anti-slip member 3 along the hinge shaft 2.1. The blocking portion 4.1 can reduce the axial shaking of the anti-slip member 3 along the hinge shaft 2.1 during the rotation of the pull ring 2, thereby improving the use stability of the pull ring 2. Furthermore, the limit block 4 is also provided with an auxiliary plate 4.2. The auxiliary plate, the blocking portion 4.1 and the limit block 4 surround a movable groove 4.3. The anti-slip member 3 is rotatably arranged in the movable groove. The movable groove 4.3 can ensure the rotation reliability of the hinge shaft and reduce the interference between the wiring harness in the converter body 1 and the anti-slip member 3. At the same time, the auxiliary plate 4.2 can also enhance the strength of the limit block 4.

[0024] On the basis of the above, the pull ring 2 is semi-circular, and two coaxial hinge shafts 2.1 are provided at both ends of the pull ring. The converter body 1 is provided with a shaft hole 1.2 corresponding to the hinge shafts. The two coaxial hinge shafts can ensure the balance of the pull ring 2 when it is pulled up, so that the USB converter can be pulled out more reliably. Further explanation: the converter body 1 is provided with a baffle 1.3 close to the shaft hole, and the limit block 4 is inserted between the baffle and the corresponding hinge shaft 2.1. The baffle 1.3 can facilitate the limit block 4 to block part of the shaft hole, thereby limiting the hinge shaft to prevent it from shaking, and then preventing the anti-slip member 3 from slipping out of the shaft hole 1.2.

[0025] On the basis of the above, an elastic pressing member for pressing the limit block is arranged between the two limit blocks 4, and the elastic pressing member can ensure that the limit block is arranged between the baffle 1.3 and the hinge shaft 2.1, so as to reliably block part of the shaft hole 1.2. Specifically, an arc-shaped connecting rod is arranged between the two limit blocks 4, and the connecting rod 4.4 is integrally formed with the limit blocks 4 at both ends. The elasticity of the connecting rod itself can reliably press the limit members at both ends, and it is easy to process and effectively reduce the processing and assembly costs.

The placement groove can facilitate the storage of the pull ring, thereby improving the convenience of use, and the pull ring 2 can be pulled out from the placement groove only when needed. On the basis of the above, in order to further improve the convenience of use of the USB converter, the pull ring is provided with a tilting portion 2.2, the cover body 1.1 is provided with an inclined surface 1.5 corresponding to the tilting portion, and the side wall of the placement groove 1.4 is also a locking protrusion 1.6 that cooperates with the pull ring. The cooperation of the tilting portion and the inclined surface can make a gap between the pull ring and the placement groove 1.4, which is convenient for the user to pull the pull ring 2 from the placement groove 1.4. The provided locking protrusion 1.6 can be locked after the pull ring 2 is stored in the placement groove to prevent the locking protrusion from accidentally rotating.
