Description

Neck quick release structure

This invention relates to a neck quick-release structure, specifically one that allows the neck part of the support frame and the display to be assembled or disassembled as needed.

Generally, most monitors are connected to the top of a tripod through a locking structure on the rear side, so that the tripod can support the monitor and be used standing on a desktop or a flat surface. This method of connecting the monitor and the tripod through a locking structure is not very convenient in assembly and disassembly and requires a lot of time.

Therefore, as shown in the "Neck Quick Detachment Structure" of the People's Republic of China Utility Model Patent No. CN217422746U, a feasible solution is provided. The top side of a support frame has a limiting groove; one end of a neck member Passing through the limiting groove to connect the support frame, the other end of the neck piece has an open slot; a sliding piece is elastically positioned inside the neck piece in a way that moves up and down, one end of the sliding piece has a pressing part, and the sliding piece There is a first buckle part communicating with the opening slot; and one end of a base is connected to a display, the other end of the base penetrates into the opening slot, the base is connected to the neck part, and the second buckle part at the other end of the base is locked The first buckle part connects the neck part and the base; after the user presses the pressing part, the first buckle part and the second buckle part can be separated, thereby allowing the display to be detached from the neck part. With the above-mentioned patented structure, the assembly of the support frame and the screen can indeed be completed quickly.
