Title:
RIB HUB CONNECTING STRUCTURE AND MUSHROOM-SHAPED TENT FRAMEWORK
Document Type and Number:
WIPO Patent Application WO/2023/245705
Kind Code:
A1
Abstract:
A rib hub connecting structure, comprising an upper rib hub (1) and a lower rib hub (2) which are coaxially arranged, an elastic assembly (3) being provided between the upper rib hub (1) and the lower rib hub (2), such that the axial distance between the upper rib hub (1) and the lower rib hub (2) can be changed reciprocatingly, wherein the elastic assembly (3) comprises a tension spring (31) and a tension spring sleeving and fixing rod (32); the upper end of the tension spring (31) is fixed to the upper rib hub (1), and the lower end of the tension spring (31) is provided with a tension spring lower opening (311); a tension spring sleeving and fixing rod protrusion portion (321) is protrudingly provided at the upper end of the tension spring sleeving and fixing rod (32) in the radial direction; the tension spring sleeving and fixing rod (32) is sleeved in the tension spring lower opening (311) with a clearance, the lower end of the tension spring sleeving and fixing rod (32) is fixed to the lower rib hub (2), and the size of the tension spring sleeving and fixing rod (32) protrusion portion is greater than the inner diameter of the tension spring lower opening (311). Also disclosed is a mushroom-shaped tent framework, comprising the upper rib hub (1) and the lower rib hub (2), and further comprising the rib hub connecting structure as described above. The beneficial effect is that: an elastic component is improved, so that a long elastic deformation range can be covered by using a short tension spring (31), thereby achieving both the unfolding effect and the folding effect.
