Description

Technical Field

[0001] The utility model belongs to the technical field of charging cables, and particularly relates to a telescopic charging cable. Background Art

[0002] At present, mobile phone charging cables on the market are generally too long. Whether they are placed when charging or not, the scene looks messy. They are even prone to entanglement with other objects. Especially when placed in a bag, they are more likely to press against other objects and break the charging cable. Moreover, there is a long charging waiting time, which causes great inconvenience to users.

[0003] Upon inquiry, the publication (announcement) number: CN 207490255 U is a mobile phone telescopic charging cable, which includes a telescopic device, an electric wire, a connector and a plug. The telescopic device includes a spring, an upper box cover, a lower box cover, steel balls and a turntable. The middle hole of the turntable is sleeved on the rotating shaft of the upper box cover. The spring is arranged inside the turntable. The middle end of the spring is arranged in the middle notch of the rotating shaft. The outer end of the spring is connected to the turntable. The steel balls are arranged in the notches of the turntable. The lower box cover is connected to the upper box cover. The electric wire is wound outside the turntable. One end of the electric wire is connected to the connector, and the other end of the electric wire is connected to the plug. The utility model adopts a rotary contraction structure, enabling the charging cable to freely contract in length, being small and exquisite, convenient to carry, capable of stretching and using in 5 grades of lengths freely, adopting a 6-pin plug design, shortening the charging time, enabling fast charging without damaging the charging device, and providing convenience for people's lives.

[0004] Although this design realizes the telescopic function of the charging cable, in the actual use process, since the charging cable often needs to be pulled out for use, during use, it is inevitable that dust and dirt adhere to its outer surface. After the data cable is retracted, a large amount of dirt accumulates inside the telescopic housing, which is prone to breeding bacteria and seriously affects the telescopic function of the data cable.

[0029] As Figure 1 shown;

[0030] A telescopic charging cable includes a left housing 1, a right housing 2, and a data cable 3 wound between the left housing 1 and the right housing 2.

[0031] In this implementation: It is found that the published (announced) number: CN 207490255 U is a mobile phone telescopic charging cable. For details, refer to the following published technology; to solve the technical problems existing in this prior art, as disclosed in the background art above, "Although this design realizes the function of telescoping the charging cable, in actual use, since the charging cable often needs to be pulled out for use, when in use, it is inevitable that dust and dirt adhere to its outer surface. After the data cable is retracted, a large amount of dirt accumulates inside the telescopic housing, which is likely to breed bacteria and seriously affect the telescoping of the data cable." In combination with actual use, this problem is obviously a real and difficult problem to solve. In view of this, to solve this technical problem, a cleaning assembly 4 is added here.

[0032] As Figures 1-6 shown in the figure;

[0033] Combined with the above, it further includes a cleaning component 4 provided on the left housing 1 and the right housing 2;

[0034] The cleaning component 4 includes an upper cleaning cotton 41 provided at the data line 3 outlet of the left housing 1 and the right housing 2, and a sliding rod 42 slidably provided on the left housing 1 and the right housing 2.

[0043] The working principle of the present utility model:

[0044] The sliding plate 43 slides upward under the action of the spring 46. At this time, the sliding plate 43 drives the sliding rod 42 to slide upward on the left housing 1 to play a guiding role. Furthermore, the lower cleaning cotton 44 is pushed by the sliding plate 43 to approach the upper cleaning cotton 41. Then, the data cable 3 is clamped by the lower cleaning cotton 44 and the upper cleaning cotton 41. When the data cable 3 is retracted, the outer surface of the data cable 3 is cleaned by the lower cleaning cotton 44 and the upper cleaning cotton 41, so that the data cable 3 remains clean and the accumulation of dirt inside the telescopic housing is prevented.

[0045] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions recorded in the foregoing embodiments or perform equivalent replacements for some of the technical features.
