Cable reel for audio-visual device
A cable reel for audio-visual device includes an upper base and a lower base attracted to an external device. An audio-visual device hangs on a top of the lower base. The upper base cooperates with the lower base whereby connection cables are spooled and accommodated in an upper circular groove of the upper base and a lower circular groove of the lower base. The present invention places the audio-visual device so that a user can easily spool connection cables of the audio-visual device with one hand. Once the audio-visual device is not needed, the user can rapidly and conveniently manage cables and place the audio-visual device without worrying about the inner breaking of the connection cables resulted from entangling the connection cables.
1. A cable reel for audio-visual device comprising:
an upper base with a side thereof annularly provided with an upper circular groove, and said upper base is attracted to an external device, and a top of said upper base is provided to an audio-visual device for hanging; and
a lower base with a side thereof annularly provided with a lower circular groove, and said lower base is attracted to said external device and arranged under said upper base, and said lower base cooperates with said upper base whereby said upper circular groove and said lower circular groove accommodate connection cables of said audio-visual device spooled around said upper base and said lower base,
wherein said lower base is selectively fastened with said upper base, and when said lower base is fastened with said upper base to connect said upper circular groove with said lower circular groove, said connection cables of said audio-visual device are accommodated in said upper circular groove and said lower circular groove connected, and when said lower base is not fastened with said upper base, said connection cables of said audio-visual device are partially accommodated in said upper circular groove and said lower circular groove separating to each other.
2. The cable reel for audio-visual device according to claim 1 , wherein a bottom of said upper base is further provided with at least two fastening mother portions, and said a top of said lower base is further provided with at least two fastening subportions, and said upper base is fastened with said lower base by using said fastening mother portions and said fastening subportions.
3. The cable reel for audio-visual device according to claim 2 , wherein each of said at least two fastening mother portions and said at least two fastening subportions further comprises at least one magnetic body, and polarities of said at least two magnetic bodies of said at least two fastening mother portions are different from polarities of said at least two magnetic bodies of said at least two fastening subportions.
4. The cable reel for audio-visual device according to claim 1 , wherein said upper base further comprises a first magnetic body, and said lower base further comprises a second magnetic body, and said upper base and said lower base are attracted to said external device by using said first magnetic body and said second magnetic body.
5. The cable reel for audio-visual device according to claim 4 , wherein said external device is a computer mainframe or a metal shelf.
6. The cable reel for audio-visual device according to claim 5 , wherein said computer mainframe has a non-metallic outer case, and said computer mainframe further comprises at least one metal body arranged in said non-metallic outer case of said computer mainframe, and said first magnetic body and said second magnetic body are attracted to said non-metallic outer case by using said at least one metal body.
7. The cable reel for audio-visual device according to claim 1 , wherein audio-visual device is a head-mounted display for virtual reality or a headphone.
8. The cable reel for audio-visual device according to claim 1 , wherein said connection cables are audio cables or three-in-one cables.
9. The cable reel for audio-visual device according to claim 8 , wherein the three-in-one-cables include an HDMI cable, a USB cable and a power cable.
