Description

Technical Field

[0001] This application relates to the field of machinery, and more particularly to a linkage mechanism and a latching assembly. Background Technology

[0002] Typically, the server housing is retractable and installed within the chassis frame. A latching mechanism is provided between the housing and the chassis frame. This latching mechanism mainly includes a handle and a hook that connects to the handle. The handle rotates, causing the hook to rotate, thus enabling the housing to engage or disengage from the chassis frame.

[0003] However, most existing latching mechanisms are mechanical lever structures, with the handle and the latch rotating in the same direction. Moreover, in order to achieve the effect of saving effort, the handle is designed to be relatively long, which results in a larger space to be traversed when rotating the handle, which is not conducive to actual operation. Summary of the Invention

[0004] In view of the above, it is necessary to provide a linkage mechanism to improve the convenience of operation.

[0005] Additionally, this application also provides a snap-fit ​​component.

[0006] A linkage mechanism includes a first fixed member and a movable member. The first fixed member has a first slot extending through it. The movable member includes a handle, a steering plate, and a hook plate. The handle is rotatably connected to the first fixed member. The steering plate includes a first portion and a second portion perpendicularly connected to the first portion. The first portion is rotatably connected to the handle, and the second portion has a sliding groove extending through it. The hook plate includes a main body, a latching portion, and a sliding post. The main body is rotatably disposed on the first fixed member about a first pivot. A portion of the main body extends outward to form the latching portion, which is corresponding to the first slot. One end of the sliding post is fixed to the main body, and the other end is movably accommodated in the sliding groove. The sliding post is offset from the first pivot.

[0007] Furthermore, the extension direction of the slide groove is defined as the first direction, and the direction from the slide column to the first rotating shaft is defined as the second direction. The first direction is not perpendicular to the second direction, and the distance between the slide column and the first slot is less than the distance between the first rotating shaft and the first slot.

[0008] Furthermore, a portion of the main body extends along the second direction toward the side facing the first slot to form the latching portion.

[0009] Furthermore, the linkage mechanism also includes a connecting plate, one end of which is rotatably connected to the first part, and the other end of which is rotatably connected to the handle.

[0010] Furthermore, the handle is rotatably mounted on the first fixing member around the second pivot, and the connecting plate is rotatably mounted on the handle around the third pivot, with the second pivot and the third pivot being offset from each other.

[0011] Furthermore, the first fixing member includes a first side plate and a second side plate connected to the first side plate, the handle is rotatably disposed on the first side plate, the main body is rotatably disposed on the second side plate, and the first slot is disposed at the connection between the first side plate and the second side plate.

[0012] Furthermore, the first side plate is perpendicularly connected to the second side plate, and the first part is perpendicularly connected to the second part.

[0013] Furthermore, the linkage mechanism also includes a stop member disposed on the first side plate, the stop member being used to prevent the handle from rotating.

[0014] Furthermore, the linkage mechanism also includes an anti-slip component, which protrudes from the end of the handle opposite to the steering plate.

[0015] A snap-fit ​​assembly includes a second fixing member and a linkage mechanism as described above. The second fixing member has a second slot, which corresponds to the first slot. The snap-fit ​​portion can pass through the first slot and extend into the second slot.

[0016] The linkage mechanism provided in this application connects the handle and the latch by setting the steering plate transmission connection, so that the rotation of the handle can be different from the rotation direction of the latch in space. This is beneficial to avoid the narrow space where the server components are densely packed inside the chassis, or to reduce the working space. Attached Figure Description

[0050] The following detailed description, in conjunction with the accompanying drawings, will further illustrate this application. Detailed Implementation

[0051] To better understand the above-mentioned objectives, features, and advantages of the embodiments of this application, the application will be described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the features in the embodiments of this application can be combined with each other.

[0052] The following description sets forth numerous specific details to provide a thorough understanding of the embodiments of this application. The described implementations are only a portion, not all, of the embodiments described herein. All other implementations obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of the embodiments of this application.

[0053] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which embodiments of this application belong. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the embodiments of this application.

[0054] Please see Figure 1 and Figure 5 One embodiment of this application provides a linkage mechanism 100, which can be used for the housing of a server (e.g., a first fixing member 10) to achieve engagement and disengagement between the housing and the chassis frame (e.g., a second fixing member 201).

[0055] Please see Figure 1 and Figure 2 The linkage mechanism 100 includes a first fixing member 10 and a movable member 20 disposed on the first fixing member 10. The first fixing member 10 has a first slot 11 extending through it. A portion of the movable member 20 can movably pass through the first slot 11, and the portion of the movable member 20 passing through the first slot 11 can be engaged with other components (e.g., the second fixing member 201), thereby achieving the engagement of the housing with the chassis frame.

[0056] The first fastener 10 includes a first side plate 12 and a second side plate 13 that is vertically connected to the first side plate 12, and the first slot 11 passes through the part where the first side plate 12 connects to the second side plate 13.

[0057] The movable component 20 includes a handle 21, a steering plate 22, and a hook plate 23. The handle 21 is rotatably disposed on one side of the first side plate 12. The hook plate 23 is rotatably disposed on the side of the second side plate 13 facing the first side plate 12. The steering plate 22 connects the handle 21 and the hook plate 23.

[0058] The steering plate 22 includes a first portion 221 and a second portion 222 perpendicularly connected to the first portion 221. The first portion 221 is rotatably connected to the handle 21, and the second portion 222 is provided with a sliding groove 2221.

[0059] The hook plate 23 includes a main body 231, a latching part 232, and a sliding post 233. The main body 231 is generally plate-shaped and is rotatably mounted on the second side plate 13 about a first pivot A. A portion of the main body 231 extends outward to form the latching part 232, which corresponds to the first slot 11. One end of the first sliding post 233 is fixedly mounted on the side of the main body 231 away from the second side plate 13, and the other end of the sliding post 233 is movably accommodated in the sliding groove 2221. The sliding post 233 is offset from the first pivot A.

[0060] Please see Figure 3 and Figure 4 The linkage mechanism 100 includes a first state S1 and a second state S2. In the first state S1, the latching part 232 does not pass through the first slot 11. In the second state S2, the latching part 232 passes through the first slot 11. During use, the linkage mechanism 100 transitions from the first state S1 to the second state S2 as follows: During rotation, the handle 21 drives the steering plate 22 to move, which in turn drives the sliding column 233 to move, causing the main body 231 to rotate around the first pivot A. This allows the latching part 232 to pass through or exit the first slot 11.

[0061] The linkage mechanism 100 provided in this application connects the handle 21 and the latching part 232 via the steering plate 22, so that the rotation of the handle 21 can be in a different direction than the rotation of the latching part 232 in space. This helps to avoid the narrow space where the server components are densely packed inside the chassis, or to reduce the working space.

[0062] Please see Figure 2 In this embodiment, the slide groove 2221 has an extending direction, which is defined as the first direction X, and the direction from the slide column 233 to the first rotating shaft A is defined as the second direction Y. The first direction X is not perpendicular to the second direction Y. Specifically, when the linkage mechanism 100 is in the first state S1, the first direction X coincides with the second direction Y. When the linkage mechanism 100 is in the second state S2, the first direction X and the second direction Y are approximately at a 45-degree angle. Therefore, rotating the handle 21 by approximately a 45-degree angle will allow the linkage mechanism 100 to change from the first state S1 to the second state S2.

[0063] Please see Figure 1 and Figure 2 In this embodiment, the distance D1 between the sliding column 233 and the first slot 11 is less than the distance D2 between the first rotating shaft A and the first slot 11. Part of the main body 231 extends along the second direction Y to form the latching part 232, thereby facilitating the rotation of the main body 231 to drive the latching part 232 into or out of the first slot 11.

[0064] Please see Figure 1 and Figure 3 In this embodiment, the movable component 20 further includes a connecting plate 24, one end of which is rotatably connected to the first part 221, and the other end is rotatably connected to the handle 21. The connecting plate 24 can help reduce jamming, allowing the handle 21 to drive the steering plate 22 to move flexibly, and the connecting plate 24 can ensure that the second part 222 moves approximately in a direction parallel to the second side plate 13.

[0065] Please see Figure 1 and Figure 3 In this embodiment, the handle 21 is rotatably mounted on the first side plate 12 about a second pivot B. The connecting plate 24 is rotatably mounted on the handle 21 about a third pivot C. The second pivot B and the third pivot C are offset from each other, so that the handle 21 can drive the connecting plate 24 to rotate.

[0066] Please see Figure 1 and Figure 3 In this embodiment, the first fixing member 10 further includes a stop member 14, which is generally in the shape of a support rod cylinder. One end of the stop member 14 is fixedly disposed at a preset position (not shown) of the first side plate 12. This preset position is the position that roughly coincides with the edge of the handle 21 in the first state S1. The stop member 14 is used to prevent the handle 21 from rotating excessively.

[0067] Please see Figure 1 and Figure 3 In this embodiment, the linkage mechanism 100 further includes an anti-slip member 30, which protrudes from the end of the handle 21 away from the steering plate 22. The anti-slip member 30 is used to prevent the operator's arm from slipping when rotating the handle 21.

[0068] Please see Figure 5An embodiment of this application also provides a snap-fit ​​assembly 200, which includes a second fixing member 201 and a linkage mechanism 100. The second fixing member 201 has a second slot 202 through it, which corresponds to the first slot 11. The snap-fit ​​part 232 can pass through the first slot 11 and extend into the second slot 202 to achieve the engagement of the first fixing member 100 and the second fixing member 201. In specific use, firstly, the linkage mechanism 100 is placed in the first state S1; then, the linkage mechanism 100 in the first state S1 is positioned corresponding to the second fixing member 201, and the first slot 11 is positioned corresponding to the second slot 202; finally, the linkage mechanism 100 is changed from the first state S1 to the second state S2 so that the snap-fit ​​part 232 passes through the first slot 11 and extends into the second slot 202, completing the engagement of the linkage mechanism 100 and the second fixing member 201.

[0069] The above embodiments are only used to illustrate the technical solutions of the embodiments of this application and are not intended to limit them. Although the embodiments of this application have been described in detail with reference to the above preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions to the technical solutions of the embodiments of this application should not depart from the spirit and scope of the technical solutions of the embodiments of this application.
