Description

Technical Field

[0001] This utility model relates to the technical field of charging data cables, and in particular to a retractable charging data cable take-up box. Background Technology

[0002] In our daily lives, when charging electrical devices, we all want the charging cable to be as long as possible for easy placement. However, after charging, we want the charging cable to be as short as possible for easy storage. As a result, people invented the data cable retractor. When charging, the charging cable can be stretched to the desired length within a certain range, and after charging, the charging cable is automatically retracted into the retractor. This not only solves the problem of charging cables being too long and too short, but also solves the problem of charging cables being cumbersome and too short.

[0003] While existing charging cable retractors allow you to extend the cable to any length and automatically retract it after use, they all contain a single charging cable. When two or more electronic devices need to be charged simultaneously, you have to buy multiple charging cable retractors, which is not only costly but also makes storage difficult.

[0036] like Figure 3 , 6As shown in Figure 7, the end of the first positioning pin 13 is provided with a first guide shaft 131 facing downward, and the first guide shaft 131 falls into the first track 151 on the top surface of the first take-up reel 15; the end of the second positioning pin 25 is provided with a second guide shaft 251 facing upward, and the second guide shaft 251 falls into the second track 211 on the bottom surface of the second take-up reel 21.

[0038] like Figure 8 As shown, the inner end of the first spring 18 is fixed to the first rotating shaft 111, and its outer end is fixed to the first take-up reel 15. When the first data cable 16 is pulled outward, the first spring 18 tightens to generate take-up power for retrieving the first data cable 16. The inner end of the second spring 20 is fixed to the second rotating shaft 241, and its outer end is fixed to the second take-up reel 21. When the second data cable 17 is pulled outward, the second spring 20 tightens to generate take-up power for retrieving the second data cable 17.

[0039] like Figure 3 , 4 As shown in Figure 5, the first track 151 includes a first take-up track 1511, a first release track 1512, a first positioning port 1513, a first switching port 1514, and a first protrusion 1515. The first take-up track 1511 is located inside the first release track 1512, and the first positioning port 1513 and the first switching port 1514 are located on the channel between the first take-up track 1511 and the first release track 1512.

[0040] In use, when the second data cable 17 is pulled outward, the second guide shaft 251 slides counterclockwise in the second cable release track 2112. When the second data cable 17 is pulled to a sufficient length, the pulling stops, and when the second data cable 17 is released, under the action of the second spring 20, the second take-up wheel 21 rotates counterclockwise, and the second guide shaft 251 slides clockwise, finally falling into the second positioning port 2113 to lock the second data cable 17.

[0041] After use, pull the second data cable 17 and release it. The second guide shaft 251 slides out of the second positioning port 2113 and into the second take-up track 2111. Under the action of the second spring 20, the second take-up wheel 21 rotates counterclockwise, and the second guide shaft 251 slides clockwise along the second take-up track 2111. Whenever it passes the second positioning port 2113, since the second guide shaft 251 slides from the high position to the low position, it slides close to the inner wall of the second take-up track 2111 and will not fall into the second positioning port 2113 until the take-up is completed.

[0042] When the second data cable 17 is to be pulled out again during the take-up process, the second guide shaft 251 in the second take-up track 2111 changes from sliding clockwise to sliding counterclockwise. When the second guide shaft 251 slides past the second protrusion 2115, since the second protrusion 2115 is in a high position, and after passing the second protrusion 2115 it enters a low position. The second guide shaft 251 slides along the outer wall of the second take-up track 2111, so the second guide shaft 251 smoothly passes through the second switching port 2114 and enters the second pay-off track 2112.

[0043] The working principle of the first take-up mechanism is the same as that of the second take-up mechanism described above.
