[0029] The following is a further description with reference to the accompanying drawings and specific embodiments:

[0030] Example 1

[0031] A one-way reel, such as Figures 1-9As shown, the wire reel body 1 includes a shell 100 and a winding spring 4, a wire drum 5 and a control member 6 arranged inside the shell 100. The wire drum 5 is rotatably connected to the shell 100, and the winding spring 4 resets to drive the wire drum 5 to rotate and reel in; the wire drum 5 includes a motion path set on the wire drum 5, a limiting groove 21 is provided on the shell 100, and the control member 6 is slidably connected in the limiting groove 21, and the control member 6 includes a boss 61 extending into the motion path, and the boss 61 slides in the motion path in conjunction with the forward and reverse rotation of the wire drum 5, so as to realize the line winding. To lock and unlock the rotation of the disk 5, a central axis 31 is provided at the center of the shell 100, and one end of the spring 4 is fixedly connected to the central axis 31. In this embodiment, the shell 100 includes a bottom shell 3 and an upper shell 2 fixedly connected to the bottom shell 3. The central axis 31 is vertically arranged at the center position inside the bottom shell 3. An axial hole 52 is provided on the wire drum 5. The axial hole 52 of the wire drum 5 passes through the central axis 31 and is rotatably connected to the bottom shell 3. The movement path is provided on the upper surface of the wire drum 5, and the limit groove 21 is provided on the inner wall of the upper shell 2. The limit groove 21 is arranged opposite to the movement path.

[0032] like Figure 2 and Figure 5 As shown, the cable drum 5 has a cavity 53, and the spring 4 is located in the cavity 53. The other end of the spring 4 is fixedly connected to the cable drum 5. When the charging line on the cable drum 5 is stretched outward, the spring 4 is in a coiled state when rotating forward or reverse.

[0033] In this way, when the cable reel 5 is in the coiled state, the clockwork spring 4 has a reverse restoring force of a certain strength. When the cable reel 5 is in the unlocked state, the restoring force of the clockwork spring 4 quickly drives the cable reel 5 to rotate in the opposite direction, and quickly retracts the stretched charging cable onto the cable reel 5 and stores it in the shell 100.

[0034] like Figure 3 、 Figure 8 、 Figure 9As shown, the motion path is a path groove 51 opened on the cable drum 5, and the path groove 51 is a closed or non-closed annular groove. The path groove 51 is provided with at least one fixed corner 511 for stopping the control member 6, and the rest are non-obstacle slides. The non-obstacle slides include a first path non-obstacle slide, a second path non-obstacle slide and a third path non-obstacle slide. The first path non-obstacle slide and the second path non-obstacle slide are the sliding tracks of the protrusions on the control member in the path groove when the charging line of the cable drum is in a stretched state. The third path non-obstacle slide is the sliding track of the protrusions on the control member in the path groove when the cable drum is in a reeling state. A second guide platform 513 is provided in the second path non-obstacle slide, and the second guide platform 513 is close to the shaft hole 52. A first guide platform 512 is provided in the third path non-obstacle slide. The path between 511 and the first guide platform 512 is the first path non-obstruction slide, the second guide platform 513 surrounding the first guide platform 512 is the second path non-obstruction slide, and the third path non-obstruction slide is arranged around the fixed corner 511 and the periphery of the second path non-obstruction slide. When the boss 61 on the control member 6 slides into the fixed corner 511, the cable drum 5 is in a locked state, which is also the initial state of the reel body 1 or the travel distance and end point of the rotation of the cable drum 5. The length of the limit groove 21 is greater than the length of the control member 6. A shaft block is provided at the center of the limit groove 21. The shaft block is arranged opposite to the center axis 31 and is aligned with each other. The control member 6 is provided with an avoidance hole 62, and the shaft block is located in the avoidance hole 62. A wire hole 10 and a wire hole 20 are provided on the shell 100. The wire hole 10 and the wire hole 20 are provided to facilitate the passage of the charging cable.

[0035] Example 2

[0036] The cord reel body 1 also includes a charging cable of several lengths wound on the cable reel 5. One end of the charging cable is a fixed end, which passes through the cable reel 5 and is fixed on the cable reel 5. The end of the fixed end extends out of the shell 100 and a certain length is reserved to facilitate the rotation of the cable reel 5 and the stretching of the telescopic end. The other end of the charging cable is a telescopic end. Pulling the telescopic end of the charging cable can adjust the length of the charging cable. The telescopic end of the charging cable is provided with at least one charging plug. The two ends of the charging cable pass through the wire hole 10 and the wire hole 2 20 in a one-to-one manner and are located outside the shell 100. The charging plug is a combination of one or more of a USB male plug, a TYPE-C male plug or a Lightning male plug.

[0037] The working principle of the present utility model is as follows: the user pulls the charging cable outward, the boss 61 on the control member 6 disengages from the fixed corner 511, and while the cable drum 5 rotates, the boss 61 on the control member 6 slides into the first path non-obstructive slide in the path groove 51, and after the boss 61 contacts the first guide platform 512, the boss 61 slides toward the second guide platform 513, and when the cable drum 5 continues to rotate, the boss 61 continues to slide around the second path non-obstructive slide, and the control member 6 slides up and down or left and right in the limit groove 21 as the cable drum 5 rotates. When the cable drum 5 stops rotating, under the reset force of the spring 4, the cable drum 5 starts to rotate in the opposite direction, and the boss 61 moves along the second path non-obstructive slide. After the obstacle slide slides to contact the second guide platform 513, the boss 61 slides upward and is locked into the fixed corner 511, so that the stretched state of the cable drum 5 is locked, and the spring spring 4 is in a deformed and curled state. When the user needs to retract the charging cable, he only needs to pull the charging cable outward. At this time, the boss 61 on the control component 6 is disengaged from the fixed corner 511, and the boss 61 slides to the first path non-obstructive slide, releasing the charging cable. Under the reset force of the spring spring 4, the spring spring 4 drives the cable drum 5 to reverse rapidly, and the boss 61 slides rapidly along the third path non-obstructive slide until the stretched charging cable is completely retracted, the cable drum 5 stops rotating, and the cable reel is completed.

[0038] To sum up, the utility model is provided with a clockwork spring 4, a wire drum 5 and a control part 6 inside the shell 100 of the reel body 1, and a motion path is provided on the wire drum 5. The wire drum 5 can be locked and unlocked by cooperating with the control part 6 and the motion path. The overall structure is very simple, and the stability of the winding mechanism is better during long-term operation.

[0039] The above is only a preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, various modifications and variations of the present invention are possible. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention shall be included in the scope of protection of the present invention.
