[0054] To make the above-mentioned objectives, features and advantages of the embodiments of this application more apparent and understandable, the specific implementation methods of this application will be described in detail below with reference to the accompanying drawings.

[0055] Figure 1 This diagram illustrates the state of a node installed on a rack, as shown below. Figure 1 As shown, the node 100 provided in this embodiment can be inserted into and removed from the rack 200, and is capable of self-locking. It is understood that... Figure 1 The cabinet in this context refers to a chassis, which can be, for example, a server chassis. Figure 1 The nodes in this context are pluggable modules, which can be pluggable modules such as processor node boards, memory modules, hard disk modules, network card modules, or GPU modules. Of course, in other embodiments, the nodes can be servers, and the rack can be a rack of server racks. Multiple nodes can be set up on the rack.

[0056] like Figure 2 As shown, Figure 2 A schematic diagram of the structure of a node provided in an embodiment of this application is shown. The node 100 provided in this embodiment includes a node body 1 and a wrench 2. The wrench 2 is connected to the node body 1. The node body 1 includes a front panel 11 and a first side panel 12 and a second side panel 13 connected to the front panel 11. The first side panel 12 and the second side panel 13 are arranged opposite to each other at a distance.

[0057] Continue to refer to Figure 2 The wrench 2 includes a handle 21, a first wrench body 22, and a second wrench body 26. By holding the handle 21, the first wrench body 22 and the second wrench body 26 will rotate, thereby inserting the node 100 into the cabinet 200 or pulling the node 100 out of the cabinet 200.

[0058] It should be noted that inserting node 100 into rack 200 means connecting the node's connector to the rack's connector, and removing node 100 from rack 200 means inserting the node into the rack's connector and removing it from the corresponding rack connector. Since inserting and removing nodes requires considerable force, using a wrench allows for easier and less strenuous operation for the user.

[0059] Figure 3 yes Figure 2 The enlarged view at point A in the image is shown below. Figure 3 As shown, the first wrench body 22 includes a first wrench end 221 and a first connecting end 222, and the first wrench end 221 is rotatably connected to the first side panel 12. In this embodiment, the first wrench end 221 can be rotatably fixed to the first side panel 12 by means of a pivot pin 25.

[0060] The structure of the second wrench body 26 can be the same as that of the first wrench body 22. The second wrench body 26 includes a second wrench end and a second connecting end, and the second wrench end is rotatably connected to the second side panel 13. The following description will use the structure of the first wrench body 22 as an example.

[0061] The handle 21 is located on the facing side of the front panel 11. The two ends of the handle 21 are connected to the first connecting end 222 and the second connecting end, respectively. The handle 21 can rotate relative to the first connecting end 222 and the second connecting end to lock with the first connecting end 222 and the second connecting end, thereby driving the first wrench body 22 and the second wrench body 26 to rotate.

[0062] Therefore, by pulling the handle 21, it can be locked with the first wrench body 22 and the second wrench body 26 during rotation, thereby driving the first wrench body 22 and the second wrench body 26 to rotate, cooperating with the cabinet 200 to realize the wrench in and wrench out of the node 100.

[0063] The node provided in this embodiment can be locked with the first wrench body 22 and the second wrench body 26 during rotation by pulling the handle 21, thereby driving the first wrench body 22 and the second wrench body 26 to rotate and cooperate with the cabinet 200 to realize the insertion and removal of the node 100. When the handle 21 is pulled, the first wrench body 22 and the second wrench body 26 can move synchronously, so it can be operated with one hand, improving the operating efficiency. This operation method only requires pulling the handle 21 located on the front panel 11 to realize the insertion and removal of the node 100, so it does not occupy a large external space. Moreover, the position of the handle 21 on the front panel 11 side means that it does not occupy a lot of installation space inside the cabinet 200.

[0064] In one alternative implementation, refer to Figure 3The wrench 2 can further comprise a first locking portion 23 configured to cooperate with a pin 121 provided on the first side panel 12 to enable folding and self-locking of the wrench 2 when the wrench 2 is in a non-working state. The first side panel 12 can further comprise a limiting portion 122 configured to limit rotation of the first wrench end 221.

Specifically, the clamping hook 233 is closer to the side of the first side panel 12, so as to be able to cooperate with the pin 121. The operation section 231 is closer to the side of the front panel 11.

[0081] The fixed section 232, the pawl 2222 and the torsion spring 24 are all accommodated in the above-mentioned accommodating space 2221a, and the overall structure of the wrench 2 is more compact and smaller in size.

[0093] Correspondingly, the second side panel 13 can also be provided with a limiting portion which abuts against the second wrench body 26 to limit the rotation of the second wrench body 26. When the node 100 is inserted into the cabinet 200, the third matching surface of the second wrench body 26 first contacts and matches the protrusion corresponding to the position of the second side panel, and then the second wrench body 26 continues to rotate clockwise, and with the rotation of the second wrench body 26, the second wrench body 26 abuts against the limiting portion, at this time the second wrench body 26 will exert a force in the insertion direction on the limiting portion, thereby driving the node 100 to be inserted into the cabinet 200.

[0094] In a possible implementation, the first wrench end 221 can be formed with a matching portion 221c for matching and limiting with the limiting portion 122. The matching portion 221c can be a protruding structure formed on the first wrench end 221.

[0095] When the node 100 is pulled out of the cabinet 200, with the counterclockwise rotation of the first wrench body 22, the matching portion 221c abuts against the limiting portion 122, at this time the first wrench body 22 will exert a force in the pulling-out direction on the limiting portion, thereby driving the node 100 to be pulled out of the cabinet 200.

[0096] In a specific implementation, the handle 21 can further include a holding portion, and an operator can hold the holding portion to pull the handle, which is more convenient for the operator to insert or pull out the node 100.

[0097] The insertion and pulling-out processes of the node will be introduced below. Figures 6A to 6C , and Figures 7A to 7C The insertion and pulling-out processes of the node will be introduced below.

[0098] As shown in Figure 7A , the holding handle 21 is pushed into the node until the first matching surface 221a of the first wrench end 221 abuts against the first surface 210a of the protrusion 210, and with the rotation of the first wrench end 221, the protrusion 210 can be used as a relay point by the first wrench body 22.

[0099] The handle 21 is pushed clockwise, and after rotating to a certain angle, the pawl 2222 will engage with the tooth groove 211b, and then the handle 21 can drive the first wrench body 22 to rotate together, to Figure 7BIn the state shown, the operation section 231 of the first locking portion 23 is clamped into the unlocking groove 211c, and the second matching surface 221b of the first wrench end 221 abuts against the second surface 210b of the protrusion 210. At this time, the first wrench body 22 is limited by the limiting portion 122, and the first wrench body 22 pushes the limiting portion 122 to insert the node 100 into the cabinet 200. At this time, the pull handle 21 cannot be continuously pushed, and the torsional spring 24 begins to be stressed. Loosen the pull handle 21, and under the rebounding force of the torsional spring 24, the clamping hook 233 is clamped with the pin 121, and the self-locking of the wrench is realized, that is Figure 7C the state shown.

[0100] The process of pulling out is opposite to the process of pulling in. First refer to Figure 7C , the second matching surface 221b of the first wrench end 221 abuts against the second surface 210b of the protrusion 210, and the pull handle 21 is rotated clockwise, and rotated to Figure 7B the state shown, the pawl 2222 is locked with the tooth groove 211b, and the clamping hook 233 is unlocked with the pin 121. At this time, the pull handle 21 is rotated counterclockwise in Figure 7B the state to Figure 7A the state shown, the first matching surface 221a of the first wrench end 221 abuts against the first surface 210a of the protrusion 210, and the matching portion 221c of the first wrench end 221 pushes the limiting portion 122 to pull out the node 100 from the cabinet 200, and the pulling-out process is completed.
