Specifically, the left and right ends of the box body 10 are respectively provided with a wire port for the two sets of connection wires 20 to pass through.

The winder includes a cylinder 30 around which the connection cord 20 is wound, a coil spring 31 for driving the cylinder 30 to rotate, and a brake device for restricting a rotation state of the cylinder 30. The connection cord 20 is wound around the cylindrical body 30 in advance, one end of the connection cord 20 is exposed outside the case 10, and the user pulls the connection cord 20 outward and stretches the connection cord 20. When the connecting wire 20 is pulled out to a desired length, the brake device limits the rotation of the barrel 30, so that the connecting wire 20 maintains the length for the user to use. When the user needs to rewind the connecting wire 20, the rewinding locking state of the braking device is contacted, so that the connecting wire 20 is pulled back to be wound under the rewinding action of the winder.

So set up, through coiling power adapter's connecting wire 20 with the winder, the winder is provided with wind spring 31 and can realizes the automation of connecting wire 20 and withdraws, and the winder is provided with arresting gear, can prevent that connecting wire 20 from withdrawing when connecting wire 20 pulls out automatic locking to can withdraw connecting wire 20 after pulling connecting wire 20 again when needs are withdrawed, use in a flexible way.

As shown in fig. 2, in some embodiments, the winders are arranged in a group and are wound with the connection wires 20 connected to the output terminals of the adaptor body 50 to achieve automatic winding of the output terminal wires. The adapter body 50 is an existing product, and is not particularly limited in this application, and the winder is installed on the left side inside the box body 10, and the adapter body 50 is installed on the right side inside the box body 10.

According to the understanding of the technical solution of the present invention by those skilled in the art, the position and number of the winders in the present invention can be adjusted according to the need, for example, the winders are set as a group and are connected with the connecting wire 20 connected with the input end of the adapter body 50 by wire; alternatively, the two groups of winders are disposed on the left and right sides of the adaptor body 50 respectively to correspond to the two groups of connecting wires 20 for wire wrapping, so that the above equivalent structure can be understood as an equivalent embodiment using the solution of the present invention.

As shown in fig. 2 to 3, in some embodiments, the cylinder 30 is provided in a cylindrical structure, and is provided at an outer circumferential wall thereof with a wire groove around which the connection wire 20 is wound in a circumferential direction, so that an intermediate portion of the connection wire 20 is wound inside the wire groove. The central shaft 32 is arranged in the box body 10 along the vertical direction, the cylinder 30 is coaxially sleeved on the peripheral wall of the top end of the central shaft 32, the bottom end of the central shaft 32 is connected with the box body 10, the central shaft 32 is fixed with the box body 10, and the cylinder 30 rotates around the axis of the central shaft 32. The coil spring 31 is sleeved outside the central shaft 32 and acts between the central shaft 32 and the cylinder 30, one end of the coil spring is connected with the central shaft 32, and the other end of the coil spring is connected with the cylinder 30, so that the coil spring 31 provides power for the rotation of the cylinder 30 to automatically wind the connecting wire 20.

With this arrangement, when the user pulls the cord 20 outwardly, the cord 20 rotates the barrel 30 to cause the coil spring 31 to elongate and expand and accumulate elastic potential energy, and when the cord 20 is released, the coil spring 31 releases the elastic potential energy to cause the barrel 30 to reverse and then wind the cord 20 around the barrel 30.

As shown in fig. 3 to 4, in some embodiments, the braking device includes a connecting shaft 40 disposed at a top end inside the case 10 and disposed coaxially with the central shaft 32, a ratchet wheel 41 sleeved on an outer circumferential wall of the connecting shaft 40, a gear shaping 42 movably connected with the ratchet wheel 41, and an elastic member interfering with a rotation state of the gear shaping 42. The bottom end of the connecting shaft 40 is connected with the cylinder 30, and the top end of the connecting shaft 40 is rotatably connected with the box body 10, so that the cylinder 30 and the connecting shaft 40 synchronously rotate around the axis of the cylinder 30. In addition, the ratchet wheel 41 is fixedly connected with the connecting shaft 40 to ensure that the rotation state of the ratchet wheel 41 is consistent with that of the connecting shaft 40, so that the interference of the rotation state of the cylinder 30 is realized by the interference of the rotation state of the ratchet wheel 41 by the gear shaping 42.

Specifically, at least three sets of arc-shaped slots 411 are formed in the outer edge of the ratchet wheel 41, and a plurality of tooth slots 412 are formed in any two adjacent sets of arc-shaped slots 411, wherein the opening direction of the tooth slots 412 is the same as the rotation direction of the ratchet wheel 41.

The movable end of the gear shaping 42 in the static state points to the center of the ratchet wheel 41, and the distance between the movable end of the gear shaping 42 in the static state and the center of the ratchet wheel 41 is smaller than the radius of the ratchet wheel 41 and larger than the distance between the bottom of the arc-shaped groove 411 and the center of the ratchet wheel 41, so that the free end of the gear shaping 42 can be in contact with the arc-shaped groove 411, and the reversing of the gear shaping 42 is realized. The elastic component provides a reset driving force for the gear shaping 42 after the gear shaping 42 rotates to deviate from the static state, so as to adjust the state of the gear shaping 42.

With such an arrangement, when the user pulls the connection cord 20 outwards, since the rotation direction of the ratchet wheel 41 is opposite to the opening direction of the tooth socket 412, no matter the free end of the gear rack 42 points in the same direction or opposite to the rotation direction of the ratchet wheel 41, the gear rack 42 will not be caught in the tooth socket 412, and at this time, the connection cord 20 can be pulled out freely outwards. When the user pulls the connecting wire 20 to a desired position, the cylinder 30 tends to rotate under the driving of the coil spring 31, so that the ratchet wheel 41 also tends to rotate, and the gear 42 is engaged with the tooth slot 412, thereby preventing the ratchet wheel 41 from rotating and the connecting wire 20 from being retracted.

As shown in fig. 3 to 5, in some embodiments, the elastic member includes a mounting plate 45 disposed at the top end inside the case 10, a rotating shaft 43 perpendicular to the mounting plate 45 and connected thereto, and a torsion spring 44 sleeved on the outer circumferential wall of the rotating shaft 43, one end of the gear rack 42 far away from the ratchet wheel 41 is connected to one end of the rotating shaft 43 far away from the mounting plate 45, two ends of the torsion spring 44 extend outwards, one end of the torsion spring is connected to the gear rack 42, and the other end of the torsion spring is connected to the mounting plate 45.

The rotating shaft 43 is rotatably connected with the mounting plate 45, the gear shaping 42 is fixedly connected with the rotating shaft 43, the gear shaping 42 freely rotates around the axis of the rotating shaft 43 around the rotating shaft 43, and the torsion spring 44 provides reset driving force for the gear shaping 42.

So configured, when the user needs to withdraw the cord 20, the teeth 42 are braked due to the engagement with the gullets 412. The first contact braking state is required, because when the gear shaping 42 is located in the arc slot 411, the gear shaping 42 will change the reverse direction according to the change of the rotation direction of the subsequent ratchet wheel 41. At this time, the connecting wire 20 is further pulled outward, so that the gear shaping 42 is reversed in the arc slot 411 after passing through the tooth slot 412, and the connecting wire 20 is retracted by the coil spring 31 after the external force is removed.

The following explains the operation of the present application:

when the user needs to use the power adapter, the user pulls the connection cord 20 outwards, and since the rotation direction of the ratchet wheel 41 is opposite to the opening direction of the tooth socket 412, no matter the free end of the gear tooth 42 points in the same direction or opposite to the rotation direction of the ratchet wheel 41, the gear tooth 42 will not be caught in the tooth socket 412, and at this time, the connection cord 20 can be pulled out freely outwards. When the user pulls the connecting wire 20 to a desired position, the cylinder 30 tends to rotate under the driving of the coil spring 31, so that the ratchet wheel 41 also tends to rotate, and the gear 42 is engaged with the tooth slot 412, thereby preventing the ratchet wheel 41 from rotating and the connecting wire 20 from being retracted.

When the user needs to withdraw the connecting wire 20, the locking state is maintained since the gear teeth 42 are engaged with the teeth grooves 412. The first contact braking state is required, because when the gear shaping 42 is located in the arc slot 411, the gear shaping 42 will change the reverse direction according to the change of the rotation direction of the subsequent ratchet wheel 41. At this time, the connecting wire 20 is pulled outwards continuously, so that the gear shaping 42 is reversed in the arc-shaped slot 411 after passing through the tooth slot 412, and after the external force is removed, the connecting wire 20 is retracted under the action of the coil spring 31.
