When at least one surrounding frame rod component rotates around the axis of the surrounding frame rod component, the other surrounding frame rod components can be driven to rotate around the axis of the surrounding frame rod component through the linkage mechanism, namely, the first locking structures on the surrounding frame rod components can be locked and unlocked simultaneously.
In this embodiment, when one of the surrounding frame rod assemblies rotates around its axis, the other surrounding frame rod assemblies are driven by the link mechanism to rotate around their axes respectively, so that the first locking structures on the surrounding frame rod assemblies can simultaneously realize locking and unlocking.
The method specifically comprises the following steps: except for the first upright component 3a, each second upright component 3b is provided with a group of linkage mechanisms. The linkage mechanism comprises two bevel gears 5, the two bevel gears 5 are respectively arranged at two sides of a vertex angle 32 of the second vertical rod component 3b, the two bevel gears 5 are meshed, the end parts of two adjacent surrounding frame rod components, namely one end part of the surrounding frame rod 11, are rotatably connected with the bevel gear 5 at the corresponding side through a first shaft 41, and the two bevel gears 5 can be rotatably arranged on the vertex angle 32 of the second vertical rod component 3b around the axial lead of the surrounding frame rod component connected with the bevel gears 5.
Therefore, at least one bevel gear 5 is connected to one frame surrounding rod assembly, when one frame surrounding rod assembly rotates around the axis of the rod assembly, the bevel gear 5 connected with the one bevel gear can be driven to synchronously rotate around the axis of the frame surrounding rod assembly relative to the vertex angle 32, so that the bevel gear 5 meshed with the bevel gear 5 can be driven to drive the frame surrounding rod assembly connected with the one bevel gear to rotate around the axis of the frame surrounding rod assembly, and accordingly, all the bevel gears 5 driven by the frame surrounding rod assembly and connected with the one bevel gear can rotate around the axis of the rod assembly relative to the vertex angle. And when the surrounding frame rod assembly is folded, the surrounding frame rod 11 rotates around the first shaft 41 relative to the bevel gear 5.
Go up to enclose frame subassembly still includes adaptor 6, and adaptor 6 sets up respectively in the both sides of the apex angle 32 of first pole setting subassembly 3a, and two adjacent enclose frame pole subassembly promptly and enclose a tip of frame pole 11 and all can set up on the adaptor 6 that corresponds one side with rotating around self axial lead, and two adaptors 6 all rotate through the apex angle 32 of first pole setting subassembly 3a through primary shaft 41 and are connected. When the first locking structure is locked or unlocked, the surrounding frame rod assembly rotates around the axis of the surrounding frame rod assembly relative to the adapter piece 6, and when the surrounding frame rod assembly is folded, the adapter piece 6 drives the surrounding frame rod 11 to rotate around the first shaft 41 relative to the top corner 32 of the first vertical rod assembly 3 a.
