Abstract
Description
Technical Field
[0001] The utility model belongs to the field of guide chains, and in particular relates to a guide chain and a server. Background Art
[0002] A guide chain is a structure used to guide between two joints that can move relative to each other, such as cables, hoses, or pipelines. Existing guide chains do not restrict the rotational direction and angle of adjacent links, which can cause the guide chain to bend randomly.
[0003] Servers on a network primarily provide computing or application services to other clients (such as personal computers, smartphones, ATMs, and other terminal devices). Generally speaking, servers have the ability to respond to service requests, provide services, and guarantee services.
[0004] Current blade servers have hard drives arranged vertically, front to back, like a drawer. In this arrangement, if the cables connecting the hard drives to the blade server (such as power cables, signal cables, and high-speed signal cables) are not kept connected to the motherboard, the blade server loses its hot-swappable functionality. Consequently, hard drive maintenance requires shutting down the system, which is inconvenient. Furthermore, if the cables remain connected to the motherboard, they can become tangled or snagged if not properly secured. Pulling on the hard drive can cause the cables to break, resulting in signal loss at best and a short circuit at worst, potentially damaging the motherboard or the hard drive. Utility Model Content
[0005] The purpose of the present invention is to provide a guidance chain and a server to overcome at least one of the above-mentioned defects in the prior art.

The first links are combined to form the entire guide chain. Combined with the settings of the first stop surface and the second stop surface, the guide chain is in a snake shape when folded, which reduces space occupancy and is conducive to organizing pipelines.

DETAILED DESCRIPTION
[0039] The present invention will now be further described with reference to the accompanying drawings and specific implementation methods.

[0041] Example 1:
[0042] like Figures 1 to 9As shown, a guide chain provided in this embodiment includes a plurality of first links 22, a second link 23, and a third link 21. The ends of the second link 23 are hinged to two adjacent first links 22, and the third link 21 is hinged to one end of the first link 22. Each of the first, second, and third links 22, 23, 21 has a guide space 3 within it. A stop 4 is provided between the first and second links 21, 23, and the first and third links 21, 21, respectively. The guide space 3 for accommodating pipelines not only effectively protects the pipelines and ensures their stability and reliability, but also provides necessary support and guidance, regulates the pipelines' trajectory, and prevents them from entanglement and twisting. The stop 4 limits the bending of the guide chain, preventing it from bending arbitrarily. The third link 21 is connected to two joint positions that can move relative to each other, and the second link 23 is used to connect the adjacent first links 22. The first links 22 are combined to form the entire guide chain. Combined with the settings of the first stop surface 42 and the second stop surface 44, the guide chain is in a snake shape when folded, which reduces space occupancy and is conducive to organizing pipelines.
[0043] The stop portion 4 includes a stop block 41 and two first stop surfaces 42. A stop zone 43 is formed between the two first stop surfaces 42 to limit the guide chain's rotation angle. The stop block 41 moves within the stop zone 43. By confining the stop block 41 within the stop zone 43, the chain link cannot rotate further when the stop block 41 contacts the first stop surfaces 42, preventing the chain link from folding back during retraction, making it impossible to retract. In this embodiment, the third link 21 and the second link 23 each have an end portion located within the first link 22, each end surface having a first stop surface 42, and the first link 22 has a stop block 41 within it. In other embodiments, the end portion of the first link 22 may be located within the third link 21 and the second link 23, each end surface having a first stop surface 42, and the third link 21 and the second link 23 may have a stop block 41 within them.
[0044] Among them, the two first stop surfaces 42 are perpendicular to each other and respectively cooperate with the two side walls opposite to the stop block 41. In this embodiment, the two side walls opposite to the stop block 41 each have a second stop surface 44. The first stop surface 42 and the second stop surface 44 are both planes. The two stop surfaces are parallel to each other. The center points of the hinges of the first link 22 and the second link 23, the center point of the stop block 41, and the center point of the first link 22 are on the same straight line. When the guide chain is extended and retracted, after the first stop surface 42 and the second stop surface 44 come into contact, the two block each other, making it impossible for the chain links to continue rotating, thereby limiting the folding angle of the guide chain. The utility model arranges the first stop surface 42 and the second stop surface 44 and their positions so that two adjacent chain links can only have one rotation direction, ensuring that the guide chain will not fold in the opposite direction during extraction and recovery, resulting in inability to recycle. In other embodiments, the center point of the hinge position of the first link 22 and the second link 23, the center point of the stop block 41 of the second link 23, and the center point of the second link 23 may be on the same straight line, and the center point of the hinge position of the first link 22 and the third link 21, the center point of the stop block 41 of the third link 21, and the center point of the third link 21 may be on the same straight line.
[0045] The third link 21, the first link 22, and the second link 23 all have an enclosure 24, which encloses the pipeline. The enclosure 24 encloses the pipeline, thereby protecting the pipeline and preventing the pipeline from escaping from the guide chain.
[0046] The guide chain further includes a mounting frame 5, with third links 21 at both ends. The sidewalls of the third link 21 have first latching portions 211, and the sidewalls of the mounting frame 5 have second latching portions 6. The first latching portions 211 and the second latching portions 6 cooperate to form mounting positions 7. The first latching portions 211 and the second latching portions 6 allow the mounting frame 5 to be detachable from the third link 21. To perform a serpentine reversal, the third link 21 can simply be removed from the mounting frame 5 and the chain can be reversed.
[0047] Among them, the first link 22 and the second link 23, and the first link 22 and the third link 21 are hinged by a pin shaft, and the axial direction of the pin shaft is perpendicular to the length direction of the first link 22, which changes the bending direction of the traditional guide chain. Combined with other structural designs of the present invention, the guide chain can bend in a serpentine shape.
[0048] Example 2:
[0049] like Figure 10As shown, this embodiment provides a server, including a cable 1, a motherboard 9, a hard disk bay 10, and the guide chain of embodiment one. The motherboard 9 and the hard disk bay 10 are mechanically connected by the guide chain. The cable 1 is provided in the guide chain. The motherboard 9 and the hard disk bay 10 are electrically connected by the cable 1. During the process of lifting out and recovering the hard disk bay 10, the setting of the guide chain ensures the stable traction of the cable 1 and the protection of the cable 1, and can keep the cable 1 in an orderly bending state after recovery, which not only reduces the space occupied, but also avoids the entanglement of the cable 1, which is beneficial to the maintenance of the server. The two ends of the cable 1 of this embodiment pass through the head and tail ends of the guide chain respectively, and the guide chain is made of iron. The use of an iron guide chain has better strength and durability, and is more protective.
