Therefore, the second connecting member 22 connected to the handle body 31 cannot rotate along its circumferential direction. At this time, the connection between the first connecting part 10 and the second connecting part 20 is completed. After the first connecting part 10 and the second connecting part 20 are connected, the two adjacent display boxes will also be connected together. When it is necessary to disconnect the connection between the first connecting part 10 and the second connecting part 20, just perform the above steps in reverse to disconnect the connection between the first connecting part 10 and the second connecting part 20.

[0064] In a specific embodiment, when using the connection mechanism provided by this embodiment to install two adjacent display boxes up and down, the locking and positioning of the connection mechanism can be achieved by only rotating the handle body. Compared with the installation method using the bottom latch in the prior art, the connection mechanism provided by this embodiment does not require pushing and pulling, so it has higher operating efficiency, occupies less space, and is more versatile.

[0065] In summary, the connection mechanism and display device provided by the present embodiment have at least the following beneficial technical effects: the connection mechanism provided by the present embodiment respectively arranges the first connection part 10 and the second connection part 20 on two adjacent display boxes, so that the two adjacent display boxes can be connected through the cooperation of the first connection part 10 and the second connection part 20. At the same time, the connection mechanism provided by the present embodiment pivotally connects the second connection member 22 to the connecting seat 21, so that the connection mechanism provided by the present embodiment can switch the second connection member 22 between the first state and the second state by rotating the second connection member 22, so that the first connection member 11 can be locked on the connecting seat 21 by the second connection member 22 in the first state when it is inserted into the connecting seat 21, thereby realizing the rapid connection of the two adjacent display boxes.

[0066] The above are only preferred embodiments of the present application and are not intended to limit the present application.
