Description

Technical Field

[0001] The utility model relates to the technical field of HDMI cables, in particular to an HDMI cable with adjustable length. Background Art

[0002] HDMI cable supports a data transmission rate of 5Gbps and can transmit up to 30 meters. The better quality HDMI cables on the market are all 24K gold-plated. Because the product supports EDID and DDC2B, devices with HDMI have the characteristics of "plug and play". The home theater audio and video system only needs two simple HDMI cables to realize the signal transmission between the signal source device to the AV amplifier, and the AV amplifier to the projector.

[0003] Traditional HDMI cables cannot quickly adjust the length of the cable according to specific length requirements. The HDMI cable is connected between two sets of devices, and people usually manually wrap the excess cable into a circle. However, the coiled cable is exposed and cannot be fixed, and the cable is easily loosened and messy.

[0004] For this reason, we propose HDMI cables with adjustable length. Utility Model Content

[0007] A spiral winding groove is provided at the outer circumference of the telescopic wire drum, and blocking bars are provided on both upper and lower sides of the inner wall surface of the winding groove.

[0008] Preferably, threaded discs are fixedly spliced ​​at both upper and lower ends of the telescopic wire reel, and two groups of the telescopic wire reels are respectively threadedly mounted on both ends of the connecting sleeve through corresponding threaded discs.

[0009] Preferably, a twist groove is provided on the outer side surface of the threaded disk at the outer side end of the telescopic wire reel, and the twist groove facilitates people to rotate the threaded disk, so that the threaded disk drives the telescopic wire reel to rotate, thereby facilitating the control of the length of the telescopic wire reel extending from both ends of the connecting sleeve.

[0010] Preferably, a signal receiving end is provided at one end of the first extension line body away from the first elastic line body, and an information sending end is provided at one end of the second extension line body away from the second elastic line body.

[0011] Preferably, the first extension line body and the second extension line body are both wound on the corresponding telescopic wire drum along the winding groove, and the first extension line body and the second extension line body are limited by the provided blocking bar.

[0012] Beneficial Effects

[0013] The utility model provides an HDMI cable with adjustable length, which has the following beneficial effects:

[0014] (1) In the HDMI cable with adjustable length, the first extension line body and the second extension line body are both wound on the corresponding telescopic wire drum along the winding groove. The first extension line body and the second extension line body are limited by the provided blocking bar, so that the first extension line body and the second extension line body are closely fitted inside the winding groove. The telescopic wire drum is controlled to rotate so that the telescopic wire drum with the first extension line body and the second extension line body wound on the telescopic wire drum is retracted into the connecting sleeve. The number of turns of the first extension line body and the second extension line body wound on the telescopic wire drum is adjusted as needed, thereby achieving the effect of freely adjusting the required length of the HDMI cable.

[0015] (2) In the HDMI cable with adjustable length, the first extension line body and the second extension line body are both wound along the winding groove on the corresponding telescopic wire drum, and the first extension line body and the second extension line body are limited by the provided blocking bar, so that the first extension line body and the second extension line body are tightly fitted inside the winding groove, thereby improving the tightness between the first extension line body and the second extension line body and the corresponding telescopic wire drum, thereby achieving the effect of preventing the line body from being loose.
