Description

Connecting rod mechanism and buckle assembly

The present invention relates to the mechanical field of the present application, and in particular to a connecting rod mechanism and a buckle assembly.

Generally, the server shell can be pulled out and placed in the chassis frame. A snap mechanism is provided between the shell and the chassis frame. The snap mechanism mainly includes a handle and a hook connected to the handle. The handle drives the hook to rotate by rotating, and the hook realizes the engagement or disengagement of the shell and the chassis frame.

However, most of the known buckle mechanisms are mechanical lever structures, where the handle and the hook rotate in the same direction, and in order to achieve the effect of labor saving, the handle is designed to be relatively long, which results in a larger space for rotating the handle, which is not conducive to actual operation.

In view of the above, it is necessary to provide a connecting rod mechanism to improve the convenience of operation.

In addition, this application also provides a snap-on assembly.

A connecting rod mechanism includes a first fixed member and a movable member, wherein the first fixed member is provided with a first slot. 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 vertically connected to the first portion, wherein the first portion is rotatably connected to the handle, and the second portion is provided with a slide slot. The hook plate includes a main body, a buckle portion, and a slide column, wherein the main body is rotatably arranged on the first fixed member around a first rotating shaft, a part of the main body extends outward to form the buckle portion, and the buckle portion is arranged corresponding to the first slot, one end of the slide column is fixed to the main body, and the other end is movably accommodated in the slide slot, and the slide column is staggered with the first rotating shaft.

Furthermore, the extension direction of the slide slot is defined as the first direction, the direction from the slide post 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 post and the first slot is smaller than the distance between the first rotating shaft and the first slot.

Furthermore, part of the main body extends along the second direction toward one side of the first slot to form the buckle portion.

Furthermore, the connecting rod 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.

Furthermore, the handle is rotatably disposed on the first fixing member around a second rotating shaft, and the connecting plate is rotatably disposed on the handle around a third rotating shaft, and the second rotating shaft and the third rotating shaft are staggered.

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.

Furthermore, the first side panel is vertically connected to the second side panel, and the first part is vertically connected to the second part.

Furthermore, the connecting rod mechanism also includes a stopper, which is arranged on the first side plate and is used to prevent the handle from rotating.

Furthermore, the connecting rod mechanism also includes an anti-slip part, which is protrudingly arranged at one end of the handle away from the steering plate.

A buckle assembly includes a second fixing member and the connecting rod mechanism as described above, wherein the second fixing member is provided with a second slot, the second slot is provided corresponding to the first slot, and the buckle portion can pass through the first slot and extend into the second slot.

The connecting rod mechanism provided in this application is provided with the steering plate to drive the connecting handle and the buckle part, so that in terms of space, the rotation direction of the handle can be different from the rotation direction of the buckle part, which is beneficial to avoid the narrow space where the server components are densely installed in the chassis frame, or reduce the working space.

In order to more clearly understand the above-mentioned purpose, features and advantages of the embodiments of this application, the following is a detailed description of this application in conjunction with the attached drawings and specific implementation methods. It should be noted that the features in the implementation methods of this application can be combined with each other without conflict.

In the following description, many specific details are explained to facilitate a full understanding of the embodiments of this application. The described embodiments are only part of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without creative labor are within the scope of protection of the embodiments of this application.

Unless otherwise defined, all technical and scientific terms used herein have the same meanings as those commonly understood by technicians in the technical field of the embodiments of this application. The terms used in this application specification are only for the purpose of describing specific implementation methods and are not intended to limit the embodiments of this application.

Please refer to Figures 1 and 5. An embodiment of the present application provides a connecting rod mechanism 100, which can be used for the casing of the server (e.g., the first fixing member 10), so as to realize the engagement and disengagement between the casing and the chassis frame (e.g., the second fixing member 201).

Please refer to Figures 1 and 2. The connecting rod 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 is provided with a first slot 11. Part of the movable member 20 can movably pass through the first slot 11, and the part of the movable member 20 passing through the first slot 11 can be engaged with other parts (for example, the second fixing member 201), thereby realizing the engagement between the housing and the chassis frame.

The first fixing member 10 includes a first side plate 12 and a second side plate 13 vertically connected to the first side plate 12, and the first slot 11 passes through the first side plate 12 and the second side plate 13.

The movable member 20 includes a handle 21, a turning 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 one side of the second side plate 13 facing the first side plate 12. The turning plate 22 is connected between the handle 21 and the hook plate 23.

The turning plate 22 includes a first portion 221 and a second portion 222 vertically 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 slide groove 2221.

The hook plate 23 includes a main body 231, a buckle part 232, and a slide post 233. The main body 231 is roughly plate-shaped, and is rotatably disposed on the second side plate 13 around a first rotation axis A. A portion of the main body 231 extends outward to form the buckle part 232, and the buckle part 232 is disposed corresponding to the first slot 11. One end of the first slide post 233 is fixedly disposed on a side of the main body 231 away from the second side plate 13, and the other end of the slide post 233 can be movably accommodated in the slide slot 2221, and the slide post 233 is staggered with the first rotation axis A.

Please refer to Figures 3 and 4. The connecting rod mechanism 100 includes a first state S1 and a second state S2. The first state S1 includes the buckle portion 232 passing through the first slot 11, and the second state S2 includes the buckle portion 232 not passing through the first slot 11. When in use, the principle of the connecting rod mechanism 100 changing from the first state S1 to the second state S2 is roughly as follows: the handle 21 drives the steering plate 22 to move during the rotation process, and the steering plate 22 drives the sliding column 233 to move, thereby causing the main body 231 to rotate around the first rotation axis A, thereby causing the buckle portion 232 to pass through or exit the first slot 11.

The connecting rod mechanism 100 provided in the present application transmits the connecting handle 21 and the buckle portion 232 by setting the turning plate 22, so that the rotation direction of the handle 21 can be different from the rotation direction of the buckle portion 232 in space, which is beneficial to avoid the narrow space where the server components are densely installed in the chassis frame, or reduce the working space.

Please refer to FIG. 2. In this embodiment, the slide groove 2221 has an extension direction. The extension direction of the slide groove 2221 is defined as the first direction X. The direction from the slide column 233 to the first rotation axis A is defined as the second direction Y. The first direction X is not perpendicular to the second direction Y. Specifically, when the connecting rod mechanism 100 is in the first state S1, the first direction X coincides with the second direction Y. When the connecting rod mechanism 100 is in the second state S2, the first direction X and the second direction Y are approximately at an angle of 45 degrees. Therefore, the handle 21 can be rotated at an angle of approximately 45 degrees to convert the connecting rod mechanism 100 from the first state S1 to the second state S2.

Please refer to Figures 1 and 2. In this embodiment, the distance D1 between the slide post 233 and the first slot 11 is smaller than the distance D2 between the first rotation axis A and the first slot 11. Part of the main body 231 extends along the second direction Y toward one side of the first slot 11 to form the buckle portion 232, so that the rotating main body 231 can drive the buckle portion 232 to enter or exit the first slot 11.

Please refer to Figures 1 and 3. In this embodiment, the movable member 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 the jamming, so that the handle 21 drives the steering plate 22 to move flexibly, and the connecting plate 24 can ensure that the second part 222 moves roughly in a direction parallel to the second side plate 13.

Please refer to Figures 1 and 3. In this embodiment, the handle 21 is rotatably disposed on the first side plate 12 around a second rotation axis B. The connecting plate 24 is rotatably disposed on the handle 21 around a third rotation axis C. The second rotation axis B and the third rotation axis C are staggered, so that the handle 21 can drive the connecting plate 24 to rotate.

Please refer to Figures 1 and 3. In this embodiment, the first fixing member 10 further includes a stopper 14. The stopper 14 is roughly in the shape of a support rod cylinder. One end of the stopper 14 is fixedly arranged at a preset position (not marked) of the first side plate 12. The preset position is a position roughly overlapping with the edge of the handle 21 in the first state S1. The stopper 14 is used to prevent the handle 21 from excessive rotation.

Please refer to Figures 1 and 3. In this embodiment, the connecting rod mechanism 100 also includes an anti-slip member 30. The anti-slip member 30 is protrudingly disposed at one 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 turning the handle 21.

Please refer to FIG. 5 , an embodiment of the present application further provides a buckle assembly 200, the buckle assembly 200 comprising a second fixing member 201 and the connecting rod mechanism 100. The second fixing member 201 is provided with a second slot 202, and the second slot 202 is provided corresponding to the first slot 11. The buckle portion 232 can pass through the first slot 11 and extend into the second slot 202, so as to realize the engagement between the first fixing member 10 and the second fixing member 201. In specific use, first, the connecting rod mechanism 100 is placed in the second state S2; then, the connecting rod mechanism 100 in the second state S2 is set corresponding to the second fixing member 201 and the first slot 11 is set corresponding to the second slot 202; finally, the connecting rod mechanism 100 is converted from the second state S2 to the first state S1 so that the buckle portion 232 passes through the first slot 11 and extends into the second slot 202, completing the engagement of the connecting rod mechanism 100 with the second fixing member 201.
