LABOR-SAVING TENT SUPPORT

Document Type and Number:

WIPO Patent Application WO/2020/056841

Kind Code:

A1

Abstract:

The labor-saving tent support, comprising an upper pan head (1), a lower pan head (2), and a pull rope structure. The upper pan head (1) is hingedly connected to the inner side ends of a plurality of long ribs; the lower pan head (2) is hingedly connected to the inner side ends of a plurality of short ribs; the outer side ends of the short ribs are hingedly connected to the middles of the long ribs in a one-to-one correspondence mode; long-short rib hinge torsion springs (31) are further provided. The long-short rib hinge torsion spring (31) is provided with a first torsion spring force arm (99) and a second torsion spring force arm (98), and the long rib (4) and the short rib (5) are fixed to the first torsion spring force arm (99) and the second torsion spring force arm (98), respectively. The pull rope structure comprises a pull rope (3) capable of pulling the upper pan head (1) and the lower pan head (2) close to each other, and the two handle ends of the pull rope (3) droop below the lower pan head (2). According to the structure, the force required for pushing the short ribs to rotate can be obviously reduced, so that the force obstacle is eliminated; the force exerting direction of a user is changed into downward force exerting below the lower pan head (2), and therefore, the height obstacle is eliminated.
