Fig. 1 is a schematic diagram of an assembly structure of a socket provided by an embodiment of the present disclosure. As shown in FIG. 1 , the socket includes a base 10 , a socket body 20 , a coil spring mechanism 30 and a power supply wire 40 .

The socket body 20 is at least partially located in the base 10 , and can be rotated and locked relative to the base 10 . The socket body 20 has opposite first surface 20 a and a second surface 20 b, the first surface 20 a has a socket 20 c for connecting a plug, and the second surface 20 b is located in the base 10 .

Both the coil spring mechanism 30 and the power supply wire 40 are located between the second surface 20 b and the base 10 . The power supply wire 40 is coiled outside the coil spring mechanism 30, and the coil spring mechanism 30 is connected to the base 10 and the socket body 20 respectively. The coil spring mechanism 30 is used to provide force to rotate the socket body 20 . One end of the power supply line 40 is electrically connected to the socket body 20 , and the other end of the power supply line 40 is located outside the base 10 .

The power supply line 40 is a flat line, that is, the length of the cross section S of the power supply line 40 is greater than the width. The cross section S is perpendicular to the length direction of the power supply line 40 . A cross-section S of the supply line 40 is schematically shown in FIG. 1 . The length direction of the cross section S is parallel to the rotation axis m of the socket body 20 , and the length direction of the cross section S is perpendicular to the width direction of the cross section S.

In the embodiment of the present disclosure, by providing the coil spring mechanism 30 between the second surface 20 b of the socket body 20 and the base 10 , the coil spring mechanism 30 is used to provide an active force for rotating the socket body 20 . By arranging the power supply wire 40 between the second surface 20b of the socket body 20 and the base 10, and coiling the power supply wire 40 outside the coil spring mechanism 30, it is beneficial to reduce the overall thickness of the socket. Since the power supply wire 40 is a flat wire, it is beneficial to reduce the overall diameter of the power supply wire 40 coiled outside the coil spring mechanism 30, thereby making the socket more compact in structure and smaller in size, which is convenient for use and storage of the socket.

As shown in FIG. 1 , the power supply line 40 includes an insulating jacket 41 and a plurality of electric cores 42 . A plurality of electric cores 42 are located in the insulating casing 41 .

The live wire 421 and the neutral wire 423 are separated by the ground wire 422 , which can reduce the possibility of a short circuit between the live wire 421 and the neutral wire 423 after the insulating jacket 41 is damaged. Even if the insulating jacket 41 is damaged, the live wire 421 and the neutral wire 423 are more likely to be in contact with the neutral wire 423, which can play a protective role and reduce the risk of electric shock.

As shown in FIG. 1 , the socket also includes an upper shell 11 , the upper shell 11 covers the socket body 20 and is connected to the base 10 . The upper shell 11 is ring-shaped to expose the first surface 20a of the socket body 20 and expose the insertion hole 20c. A wire outlet is formed between the upper casing 11 and the base 10, and one end of the power supply wire 40 protrudes from the wire outlet.

Fig. 4 is a schematic diagram of an internal structure of a socket provided by an embodiment of the present disclosure. As shown in FIG. 4 , the bottom case 211 is a ratchet, and a plurality of teeth 2111 are distributed on the outer wall of the bottom case 211 in the circumferential direction. The socket also includes a ratchet 51 located on the side of the bottom case 211 , and the ratchet 51 cooperates with the tooth 2111 on the outer wall of the bottom case 211 . The ratchet 51 and the bottom case 211 are equivalent to a ratchet mechanism. When one end of the ratchet 51 is pressed between the adjacent teeth 2111, the bottom case 211 can only rotate in one direction. When the ratchet 51 is rotated, the ratchet 51 After being separated from the bottom case 211, the bottom case 211 can rotate in two directions.

For this socket, when the ratchet 51 is between the adjacent teeth 2111, by pulling the power supply wire 40 outward, the socket body 20 can be driven to rotate in one direction. Under the cooperation of the pawl 51 and the teeth 2111 , the socket body 20 is locked relative to the base 10 . After the pawl 51 is separated from the bottom case 211, the socket body 20 can be driven to rotate by pulling the power supply wire 40 outward, and when the pull of the power supply wire 40 is stopped, the socket body 20 can be rotated in the direction of the coil spring mechanism 30. Under action, it rotates in the opposite direction, and the power supply line 40 is rolled into the socket.

Fig. 5 is a schematic diagram of installation of a pawl provided by an embodiment of the present disclosure. As shown in FIG. 5 , in this example, the pawl 51 is rotatably connected to the inner sidewall of the upper case 11 , so that the pawl 51 can be contacted or separated from the upper case 11 by rotating the pawl 51 . A torsion spring 52 is also connected between the ratchet 51 and the upper case 11 , and the torsion spring 52 is used to provide a force to make the ratchet 51 abut against the upper case 11 . Rotating the pawl 51 by external force can separate the pawl 51 from the upper housing 11 , and when the external force is removed, the pawl 51 rotates to abut against the upper housing 11 under the action of the torsion spring 52 .

As shown in FIG. 5 , the socket also includes a button 53 , which is movably connected with the side wall of the upper casing 11 . The button 53 is located on a side of the pawl 51 away from the bottom case 211 . The ratchet 51 has two opposite ends. The middle part of the ratchet 51 is rotatably connected with the upper case 11 . One end of the ratchet 51 is used to cooperate with the upper case 11 , and the other end is close to the button 53 . The pawl 51 is used to rotate when the button 53 is pressed, and is separated from the bottom case 211 .

As shown in FIG. 1 , the coil spring mechanism 30 and the power supply wire 40 are located on the side of the bottom shell 211 away from the upper cover 212 . The coil spring mechanism 30 is connected to the bottom case 211 and the base 10 respectively. The power supply wire 40 is coiled outside the coil spring mechanism 30 , so that when the power supply wire 40 is pulled out of the socket by an external force, the coil spring mechanism 30 can drive the bottom shell 211 to rotate, so that the socket body 20 rotates. During this process, the coil spring mechanism 30 stores energy. When the power supply line 40 needs to be retracted after use, the coil spring mechanism 30 releases the energy, and the coil spring mechanism 30 and the socket body 20 rotate relative to the base 10, and the power supply line 40 is drawn into the socket. The coil spring mechanism 30 is coiled between the base 10 and the socket body 20 .

Fig. 6 is a schematic structural diagram of a coil spring mechanism provided by an embodiment of the present disclosure. As shown in FIG. 6 , the coil spring mechanism 30 includes a coil spring cover 31 and a coil spring 32 . Wherein, the coil spring cover 31 is connected to the second surface 20 b of the socket body 20 .

In this example, the spring cover 31 is connected to the bottom case 211 .

The coil spring 32 is located in the coil spring cover 31 , and the coil spring 32 is connected to the base 10 and the coil spring cover 31 respectively. The power supply wire 40 is coiled on the outer side wall of the coil spring cover 31 .

When the power supply wire 40 is pulled out of the socket, the power supply wire 40 drives the coil spring cover 31 to rotate, and the coil spring cover 31 drives the socket body 20 to rotate. During this process, the coil spring 32 stores energy. When the power supply line 40 needs to be received in the socket, the coil spring 32 releases energy to rotate the coil spring cover 31. At this time, the rotation direction of the coil spring cover 31 is opposite to that when the power supply line 40 is pulled to drive it to rotate. During this process, the coiled spring cover 31 drives the socket body 20 to rotate, and during the rotation of the coiled spring cover 31 , the power supply wire 40 is coiled outside the coiled spring cover 31 .

The coil spring cover 31 may be cylindrical and arranged coaxially with the socket body 20 . The outer diameter of the coiled spring cover 31 can be smaller than that of the socket body 20, so that the socket body 20, the coiled spring cover 31 and the base 10 form an annular groove-like structure for accommodating the power supply wire 40 coiled outside the coiled spring cover 31.

Since the coil spring 32 is also connected to the coil spring cover 31, when the power supply line 40 is pulled to drive the coil spring cover 31 to rotate, the coil spring 32 can be deformed to generate elastic potential energy. During the process of rolling the power supply line 40 into the socket, the coil spring 32 recovers its deformation, and the elastic potential energy is released, driving the coil spring cover 31 to rotate.

In some examples, the first locking slot 12a can be clamped on both sides of one end of the coil spring 32 to prevent the coil spring 32 from falling out of the first locking slot 12a.
