Description

Technical Field

[0001] The present invention relates to the technical field of umbrella parts, and particularly to the reel structure of an umbrella and its umbrella framework.

Background Art

[0002] An umbrella generally consists of a plurality of parts such as an umbrella cloth, umbrella ribs, an upper reel, a lower reel, a middle rod, and a handle. The upper reel is fixed to the upper end of the middle rod in the umbrella by a fastener, and the handle is connected to the lower end of the middle rod in the umbrella by an adhesive. The umbrella ribs are removably connected to the upper reel and the lower reel respectively, and the umbrella cloth is provided on the umbrella ribs. An umbrella with such a structure is very difficult to disassemble without tools, and the umbrella itself has to be discarded. In fact, many of the umbrella parts are made of reusable materials such as plastic. Discarding them not only wastes resources but also pollutes the environment.

[0003] The frame support structure of an umbrella or tent disclosed in Chinese Patent CN204048404U consists of a support body and a frame. At least one connecting part is provided around the support body, and a connecting device is provided at the top end of the frame. The connecting device and the connecting part are pivotally installed. Among them, in the disclosed embodiment, the connecting part is a hook, a hook hole is provided in the connecting device, and the hook hole can rotate up and down with respect to the hook by being hooked on the hook. This type of frame support structure has the convenience of being easy to assemble and disassemble, but this hook frame support structure has a risk that the hook may be torn off during use.
