Description

Technical Field

[0001] This utility model relates to the field of liquid-cooled server pull-out aids, and in particular to a novel liquid-cooled server pull-out aid. Background Technology

[0002] With the increasing application of modern big data, the number of heat-generating components in servers, switches, and other functional modules is increasing, and their power consumption is also rising. Liquid cooling technology can effectively dissipate heat.

[0003] Rack-mount servers, with their compact layout and high assembly density, require efficient space utilization, making the design of the server installation / removal aids increasingly important. When liquid cooling a server, these aids ensure that functional modules are accurately inserted into the chassis slots or mate with the liquid cooling interfaces, guaranteeing a stable and airtight connection and maintaining the normal operation of the liquid cooling system. Therefore, the aids must be easy to operate and robustly reliable. Typically, one aid is installed on each side of the server to assist in the insertion and removal of the server chassis.

[0004] With the development of liquid cooling technology, manufacturers of servers, switches and other products have put forward new requirements for pull-out aids. On the basis of the original requirements, they require pull-out aids to be more labor-saving, have good human-machine operation efficiency, have more stable structure and function, and be more convenient and faster to operate. Utility Model Content

[0005] The existing pull-out aids for liquid-cooled server chassis cannot meet the requirements for their operation and efficiency.

[0006] To address the aforementioned problems, this invention proposes a novel liquid-cooled server unlocking aid. By separating the rotation center of the rotating part of the handle from the rotation center of the locking component, the lever ratio amplifies the lever operation even under significant force, allowing for easy operation of the handle. The force point of the first locking structure is at the same horizontal level as the rotation center of the self-locking component, minimizing its reaction force on the locking component and making the locking operation more effortless, thus facilitating easy unlocking. By designing the pressing arm to be larger than the lever arm from the force point of the first locking structure to the rotation center of the self-locking component, the force required to unlock the self-locking component is significantly reduced.

[0033] Third rotating axis;

[0034] The self-locking component has an L-shaped structure;

[0035] The third rotating shaft passes through one end of the L-shaped structure of the self-locking member and the receiving space, and is fixed on both sides of the receiving space. The self-locking member is rotatably connected to the fixed base through the third rotating shaft.

[0036] In conjunction with the fourth and fifth possible embodiments of this utility model, the novel liquid-cooled server unplugging device further includes:

[0037] Second elastic element;

[0043] In conjunction with the ninth and tenth possible embodiments of this utility model, the pressing arm of the self-locking member is greater than the lever arm from the force point of the first locking structure to the rotation center of the self-locking member.

When the locking component is under significant force, the lever ratio amplifies the lever's operation, making it easier to operate. The force point of the first locking structure is at the same horizontal level as the rotation center of the self-locking component, minimizing its reaction force on the locking component and making the locking operation easier and unlocking simpler. By designing the pressing arm to be larger than the lever arm from the force point of the first locking structure to the rotation center of the self-locking component, the force required to unlock the self-locking component is significantly reduced.

It is rotatably connected to the engaging part 200 and slidably connected to the second stroke hole 122.

[0064] Multiple biting gears 220 are provided on the locking component 200. After self-locking, the biting gears are locked and fixed with the frame.

[0065] Please refer to Figure 3 and Figure 4 The sliding shaft 504 is a short shaft, which can move within the accommodating space during the rotation of the rotating part 120.

[0066] Further, please refer to Figure 3 and Figure 4 The new liquid-cooled server pull-out device also includes a third rotating shaft 504. The self-locking component 300 has an L-shaped structure. The third rotating shaft 504 passes through one end of the L-shaped structure of the self-locking component 300 and the receiving space 440, and is fixed on both sides of the receiving space 440. The self-locking component 300 is rotatably connected to the fixed base 400 through the third rotating shaft 504.

[0067] Please refer to Figure 3 and Figure 4 The third rotating shaft 504 passes through the round hole 310 of the self-locking member 300 and is fixed on the round holes 430 on both sides of the receiving space 440.

[0068] Further, please refer to Figure 3 and Figure 4The new liquid-cooled server puller also includes a second elastic element 301, the two ends of which abut against the fixed base 400 and the self-locking element 300 respectively, to provide a rebound force.

[0069] Please refer to Figure 3 The bottom of the self-locking member 300 is provided with a guide cylinder 320, one end of the second elastic member 301 is fixed in the guide cylinder, and the other end abuts against the bottom of the receiving space 440.

[0070] Further, please refer to Figure 3 and Figure 4 The self-locking member 300 and the rotating part 120 are respectively provided with a first locking structure 330 and a second locking structure 123 at their mutual contact portions. The force-bearing point of the first locking structure 330 is located at the same horizontal position as the rotation center of the self-locking member 300 (corresponding to the third rotation axis 504). The first locking structure 330 and the second locking structure 123 are used to lock the operating handle under the action of the rebound force of the second elastic member.

[0071] In this embodiment, the force-bearing point of the first locking structure 330 is at the same horizontal position as the rotation center of the self-locking member 300 (corresponding to the third rotation axis 504), thereby minimizing the reaction force on the locking member 200 and making the rotation operation of the locking member 200 easier, thus allowing for easy unlocking.

[0072] Further, please refer to Figure 3 and Figure 4 The other end of the L-shaped structure of the self-locking member 300 is provided with a pressing part 340, which is used to disengage the self-locking member 300 from the operating handle 100 by pressing, so as to unlock it.

[0074] Furthermore, the pressing arm of the self-locking member 300 is greater than the force arm from the point of force application of the first locking structure 330 to the rotation center of the self-locking member 300 (corresponding to the third rotation axis 504).

[0075] In this embodiment, by designing the pressing arm to be greater than the force arm from the point of force application of the first locking structure 330 to the rotation center of the self-locking member 300 (corresponding to the third rotation axis 504), the force required to unlock the self-locking member can be greatly reduced.

[0076] The novel liquid-cooled server unlocking device of this invention separates the rotation center of the rotating part 120 of the rotating handle 100 (corresponding to the second rotating shaft 502) from the rotation center of the locking member (corresponding to the first rotating shaft 501). When the locking member 200 is under great force, the lever ratio amplifies the lever, making it easy to operate. The force point of the first locking structure 330 is at the same horizontal position as the rotation center of the self-locking member 300 (corresponding to the third rotating shaft 504), thus minimizing the reaction force on the locking member 200 and making the rotation of the locking member 200 easier, allowing for easy unlocking. By designing the pressing arm to be larger than the lever arm from the force point of the first locking structure 330 to the rotation center of the self-locking member 300 (corresponding to the third rotating shaft 504), the force required to unlock the self-locking member can be greatly reduced.
