Description

Technical Field

[0001] The utility model relates to the technical field of conversion joints, in particular to a high-definition HDMI conversion cable for video transmission. Background Art

[0002] The function of HDMI cable is to transmit high-definition video and multi-channel audio data without any compression. At the same time, there is no need for digital / analog or analog / digital conversion before signal transmission, which ensures the highest quality audio and video signal transmission. HDMI cable is mainly used for video and audio signal transmission of plasma TVs, high-definition players, LCD TVs, rear-projection TVs, projectors, DVD recorders / players, D-VHS recorders / players and digital audio and video display devices. In actual use, it has the advantages of simple structure, stable transmission and good use effect.

[0003] The prior art discloses a HDMI adapter cable with a built-in storage function, which is published as CN212849216U, and includes a box body, a VGA connector, a connecting cable, an HDMI connector, a rotating shaft, a crank, a driving roller, a semicircular groove, a slide groove, a card block, a spring, a support bar, a screw rod, a rotating wheel, a clamping block and a clamping groove. When the HDMI connector needs to be extended and lengthened, the connecting cable is pulled outward through the HDMI connector to be pulled out of the box body. When the connecting cable is pulled out of the box body, two driving rollers are driven to rotate, and the corresponding driving rollers are driven to rotate when rotating, so that the card block continuously moves in multiple semicircular grooves. When the card block is stuck in the corresponding semicircular groove, the driving roller is limited. When the HDMI connector needs to be stored, the corresponding rotating shaft is driven to rotate by the crank, and the rotating shaft drives the corresponding driving roller to rotate. The driving roller can recycle the extended connecting cable into the box body by rotating, thereby completing the storage of the HDMI connector and the connecting cable.

[0004] In the above utility model, when the connecting wire is moved out of the box body, there is no cleaning structure, and external dust or impurities will contact the connecting wire. When the user rotates the driving roller to store the connecting wire, the connecting wire will carry the dust or impurities inside the box body. After using it for a period of time, the box body needs to be opened to clean the dust or impurities inside the box body. Since the internal space of the box body is small, the cleaning work of this utility model is inconvenient.

[0005] Currently, no effective solution has been proposed for the problems in the related technologies. Utility Model Content
