Description

Technical Field

[0001] The present invention relates to the technical field of cable management, and more particularly to an adjustable automatic retractable cable management device. Background Art

[0002] With the widespread use of electronic devices, the number and types of cables used are increasing. In addition, servers in data centers need to be pulled out and reset during use. This requires a certain amount of cable margin so that there is enough cable length for the server to operate when the server is pulled out and reset.

[0003] At present, some cable management devices used for servers do not have a folding function, which will result in the cables being unable to be completely reset during the resetting process of the server, and the cables may be entangled, which will affect the next pulling-out operation of the server. Although some cable management devices currently have the function of folding cables, and change the angle between the two straight rods by pulling force, and adjust the length of the cable by folding the two straight rods; the length of this cable management device is fixed and can only be applied to a smaller range of length sizes. For cables that are too long or too short, different cable management devices need to be replaced, which reduces the practicality of the cable management device, thereby increasing the installation speed of the cable management device and reducing the work efficiency of cable management.

[0040] See also Figure 9 A second U-shaped groove 707 is provided on the surface of one end of the fourth U-shaped connecting block 706 facing the third circular rotating block 704. The upper and lower ends of the fourth U-shaped connecting block 706 on the side away from the reset component 6 are connected to third rectangular connecting blocks 708. Each third rectangular connecting block 708 is connected to a third slider 709 at one end away from the reset component 6. The outer surface of the third slider 709 is connected to a cable arrangement block 710. The cable channel formed by the second U-shaped groove 707 and the annular groove 705 allows the surface of the third circular rotating block 704 to contact the surface of the cable, thereby increasing the friction between the third circular rotating block 704 and the cable, and then as the third circular rotating block 704 rotates, the cable will be driven to perform a telescopic operation.

[0041] See also Figure 9 , cable wiring grooves 711 are opened on the surfaces of both ends of the cable wiring block 710, and fourth rectangular sliding grooves 712 are opened on the upper and lower sides of the end of the cable wiring block 710 facing the fourth U-shaped connecting block 706, and the upper and lower sides of the end of the fourth U-shaped connecting block 706 facing the folding component 5 are connected to fourth rectangular connecting blocks 713, the fourth rectangular connecting block 713 is rotatably connected to the second circular rotating rod 701, and the second circular rotating rod 701 is rotatably connected to the circular connecting hole 602.

[0042] Specifically, the first sliding block 509, the third T-shaped connecting block 507 and the second U-shaped connecting block 508 of the extension component 502 are all equipped with cable guide blocks to guide the cables to be arranged in layers; the fourth rectangular slide groove 712 of the cable arrangement block 710 slides with the fourth U-shaped connecting block 706 to dynamically adjust the direction of the cables to avoid cross-entanglement. At the same time, the third circular rotating block 704 and the second U-shaped groove 707 of the fourth U-shaped connecting block 706 form a closed channel to ensure that the cables move along the preset path during the compensation process, thereby improving the stability of retraction and extension.

[0043] The second sliding groove 8 is matched with the second circular rotating rod 701 , the lower end of the second circular rotating rod 701 is matched with the circular connecting hole 602 , and the third sliding block 709 is installed in the inner cavity of the fourth rectangular sliding groove 712 .

[0044] Working principle: First, connect one end of the cable to the connecting device to which the cable is to be connected. Then, when the connecting device is in use, the connected device needs to be moved. At this time, a pulling force is generated on the connecting device, thereby driving the second T-shaped connecting block 504 and the first sliding block 509 to move along the first sliding groove 4 toward the connecting device. As the first sliding block 509 and the second T-shaped connecting block 504 continue to move toward the connecting device, the third T-shaped connecting block 507 and the second U-shaped connecting block 508 in the plurality of extension components 502 are extended, and the circular moving rod 511 is moved toward the connecting device.

[0045] As the circular moving rod 511 moves, the first circular connecting block 513 is driven to move along the circular frame 510 toward the connection device, thereby causing the first return spring 512 to perform a contraction operation. If the first return spring 512 is contracted to the extreme and the mobile device is still moving, the first T-shaped connecting block 501 will verify that the first slide groove 4 is moving toward the connection device. As the first T-shaped connecting block 501 moves, the second slider 601 is driven to move along the circular guide rod 603 toward the connection device, thereby causing the second return spring 604 to perform a contraction operation and the second circular rotating rod 701 to move toward the connection device, thereby causing the third T-shaped connecting block 507 and the second U-shaped connecting block 508 to perform an expansion operation.

[0046] As the second circular rotating rod 701 moves, the third circular rotating block 704, the fourth U-shaped connecting block 706, the fourth rectangular connecting block 713, the third rectangular connecting block 708 and the third slider 709 will be driven to move along the second slide groove 8 and the fourth rectangular slide groove 712. In the process of movement of the cable compensation component 7, the first gear 702 will be rotated along the first rack 703, thereby driving the second circular rotating rod 701 to rotate clockwise, thereby driving the third circular rotating block 704 to rotate, and then utilizing the friction force of the surface of the third circular rotating block 704 on the cable to transport the cable through the cable channel toward the retracting component 5, thereby performing a cable compensation operation on the cable in the retracting component 5, thereby increasing the movable length of the cable;

[0047] When the third T-shaped connecting block 507 and the second U-shaped connecting block 508 in the several extension components 502 form a straight line, the second return spring 604 will shrink to the extreme and the first gear 702 will stop rotating. At this time, if the connecting device continues to move, it will use the length of the compensation cable to move until the connecting device stops moving. When the connecting device returns to its original position, the first return spring 512 and the second return spring 604 will perform a reset operation, thereby reversing the first gear 702, and then returning the folding component 5, the reset component 6 and the cable compensation component 7 to their original positions, thus ending all operations.
