Abstract:
The present utility model relates to a self-locking foldable bracket and a foldable chair. The self-locking foldable bracket comprises two symmetrical foldable side support structures and a linkage assembly connected between the two side support structures. The linkage assembly comprises two side rods, two crossing rods and two connecting rods; during rotation, the crossing rods and the connecting rods have a limit position; the linkage assembly has a working state in which the crossing rods move downwards over the limit position and then abut against the side rods, and a folded state in which the crossing rods move upwards over the limit position and leave the side rods; when the linkage assembly is in the working state, the linkage assembly is unfolded and can maintain a distance between the two side support structures; when the linkage assembly is in the folded state, the two side support structures are driven to get close to each other. According to the self-locking method in the present utility model, the structure is simple, an additional locking structure is not required, operation is convenient, and safety and reliability are achieved. Moreover, an unlocking method is very simple, that is, the linkage assembly can be folded and the two side support structures can get close to each other as long as the crossing rods are lifted upwards.
