Abstract

Disclosed in the present application is a buckling device and a chassis. The buckling device includes a first main body, a snap member, and a sliding member. The first main body is configured to be fixed within a box. The snap member is configured to be connected to a functional component. The sliding member is slidably connected to the first main body. The snap member is rotationally connected to the first main body and held against the sliding member, and the snap member is configured to drive the sliding member to slide during rotation, and the snap member is buckled and connected to the first main body when the sliding member is located at a first preset position protruding outside the box. When an area near a functional component needs to be avoided, rotate the snap member and drive the functional component to rotate to expose the avoidance space.

First claim

What is claimed is:

1. A buckling device comprising: a first main body configured to fix in a box; a snap member configured to connect a functional component; and a sliding member slidably connected to the first main body, wherein the snap member is rotatably connected to the first main body and the snap member is held against the sliding member such that the snap member is configured to drive the sliding member to slide during rotation, and the snap member is engaged and connected to the first main body when the sliding member protrudes at a first preset position outside the box; and the buckling device further comprises at least one limiting member, one of the first main body and the sliding member is connected and fixed to the limiting member, and another of the first main body and the sliding member is provided with at least one groove, and the limiting member is slidably disposed on the groove; and the buckling device further comprises a rotating shaft, the first main body and the snap member are rotationally connected through the rotating shaft, and the rotating shaft is offset from a sliding path of the sliding member; and the snap member is provided with a restraining portion, the restraining portion is spaced apart from the rotating shaft, a peripheral side of the restraining portion is provided with a first arc surface, an outer peripheral wall of the sliding member is provided with a second arc surface, and the first arc surface is in contact with and tangent to the second arc surface.

2. The buckling device of claim 1 , wherein:
the groove includes a first groove and a second groove, a projection of the first groove on the first main body is located within a projection of the second groove on the first main body, and the first groove is closer to the first main body than the second groove; and
the limiting member comprises a connecting portion and a limiting portion, the connecting portion is configured to be connected to the first main body through the first groove and the second groove, and the limiting portion is located in the second groove and the limiting portion stops on one side of the sliding member away from the first main body.

3. The buckling device of claim 1 , wherein a plurality of grooves is spaced apart on the sliding member, the buckling device further comprises a plurality of the limiting members, and each limiting member is connected to the first main body and slidably disposed within one groove.

4. The buckling device of claim 1 , wherein the sliding member is disposed between the first main body and the snap member, the snap member defines a buckle hole, the first main body is provided with a convex buckle, and the convex buckle is buckled and connected to the buckle hole.

5. A buckling device comprising:
a first main body configured to fix in a box;
a snap member configured to connect a functional component;
a sliding member slidably connected to the first main body, and
wherein the snap member is rotatably connected to the first main body and the snap member is held against the sliding member such that the snap member is configured to drive the sliding member to slide during rotation, and the snap member is engaged and connected to the first main body when the sliding member protrudes at a first preset position outside the box,
wherein the buckling device further comprises at least one limiting member, one of the first main body and the sliding member is connected and fixed to the limiting member, and another of the first main body and the sliding member is provided with at least one groove, and the limiting member is slidably disposed on the groove, the buckling device further comprises a rotating shaft, the first main body and the snap member are rotationally connected through the rotating shaft, and the rotating shaft is offset from a sliding path of the sliding member, and

wherein the sliding member is disposed between the first main body and the snap member, the snap member defines a buckle hole, the first main body is provided with a convex buckle, and the convex buckle is buckled and connected to the buckle hole.

6. The buckling device of claim 5 , wherein:
the groove includes a first groove and a second groove, a projection of the first groove on the first main body is located within a projection of the second groove on the first main body, and the first groove is closer to the first main body than the second groove; and
the limiting member comprises a connecting portion and a limiting portion, the connecting portion is configured to be connected to the first main body through the first groove and the second groove, and the limiting portion is located in the second groove and the limiting portion stops on one side of the sliding member away from the first main body.

7. The buckling device of claim 6 , wherein a plurality of grooves is spaced apart on the sliding member, the buckling device further comprises a plurality of the limiting members, and each limiting member is connected to the first main body and slidably disposed within one groove.

8. The buckling device of claim 6 , wherein the snap member is provided with a restraining portion, the restraining portion is spaced apart from the rotating shaft, a peripheral side of the restraining portion is provided with a first arc surface, an outer peripheral wall of the sliding member is provided with a second arc surface, and the first arc surface is in contact with and tangent to the second arc surface.

9. A chassis comprising a box, a functional component, and a buckling device, the first main body fixed inside the box, wherein the buckling device comprises: a first main body configured to fix in a box; a snap member configured to connect a functional component; and a sliding member slidably connected to the first main body, wherein the snap member is rotatably connected to the first main body and the snap member is held against the sliding member, such that the snap member is configured to drive the sliding member to slide during rotation, and the snap member is engaged and connected to the first main body when the sliding member protrudes at a first preset position outside the box; and the buckling device further comprises at least one limiting member, one of the first main body and the sliding member is connected and fixed to the limiting member, and another of the first main body and the sliding member is provided with at least one groove, and the limiting member is slidably disposed on the groove; and the buckling device further comprises a rotating shaft, the first main body and the snap member are rotationally connected through the rotating shaft, and the rotating shaft is offset from a sliding path of the sliding member; and the chassis further comprises a cover, the cover is connected to the box, and the cover is pressed and fixed the sliding member.
