Document Type and Number:
WIPO Patent Application WO/2023/087422
Kind Code:
A1
Abstract:
A press-lock tent framework structure, comprising a runner and supporting rods (2) having inner side ends connected to the runner. The runner comprises a runner upper piece (11) and a runner lower piece (12) which can be vertically assembled. The inner side ends of the supporting rods (2) are connected, in a vertically swingable manner, into a space formed by the assembled runner upper piece (11) and runner lower piece (12). A button mounting hole (112) is axially formed in the runner upper piece (11) in a penetrating manner, and a button (3) is inserted into the button mounting hole (112) and can move axially. Supporting rod rotation limiting blocks (43) are provided along the radial direction of the button (3) in a protruding manner, and are fixedly connected to the button (3). The inner side ends of the supporting rods (2) are provided with recessed supporting rod rotation limiting grooves (21). When the supporting rods (2) are in an unfolded state, the supporting rod rotation limiting blocks (43) adaptively extend into the supporting rod rotation limiting grooves (21). The beneficial effect is that a good locking effect can be formed on a single-runner middle-shaft-free tent framework.
