Abstract
The utility model relates to an axial compression folding locking mechanism which includes an upper joint and a lower joint which are articulated together, a sliding shaft arranged in the lower joint, and a poke mechanism poking the sliding shaft to slide; the interior of the upper and lower joints is provided with the upper and lower half-troughs which are assembled with the sliding shaft; the poke mechanism can make the sliding shaft to slide into the trough formed by the upper and lower half-trough, thus the upper and lower joints are fixed together; the sliding shaft is contacted with the whole trough, is subject to a reasonable force; the whole structure is simpler. As the upper and lower joints are provided with assembled upper and lower boss and upper and lower opening, when the vibration is produced under the condition of the external force, the connection of the upper and lower joints is more reliable. The center of the two half-trough has the vertical displacement after the upper and lower joints are folded, the sliding shaft which is positioned in the same horizontal line of the axes line of the lower half-trough forces the axes line of the upper half-trough to be close to the axes line of the sliding shaft, thus the upper and lower joints are fixed and assembled together to make the connection between the upper and lower joints more stable and move reliably.
