Description

A kind of folding umbrella framework that is difficult for hindering hand

The utility model relates to a kind of parachute kit, particularly a kind of umbrella frame frame that is difficult for hindering hand.

Existing parachute kit divides with regard to its structure, and two kinds of forms are arranged, and a kind of is not collapsible, and another kind is folding.The former mechanism is simple, and component strength is good, and it is convenient, stable to open, draw in.But its shortcoming is to take up an area of greatlyyer, carries inconvenience.Another kind of folding umbrella, its advantage are that occupation of land is less, easy to carry, but its shortcoming is mechanism's complexity, and stability of strutting system, intensity are all relatively poor.Be this skeleton part to umbrella, particularly play the facial bone and the fulcra of main support effect, the intensity of requirement is higher, increasing its intensity, thereby increases the stability of its use.Therefore the rod member that fulcra and facial bone are made the U-shaped cross section alleviates its weight to increase its intensity.The skeleton of general folded umbrella includes umbrella bar, fixed nest holder, movable nest holder, facial bone and fulcra, its facial bone is shorter, fulcra are longer, fixed nest holder is packed in the top of umbrella bar, on the movable nest holder suit umbrella bar, facial bone is housed on fixed nest holder, fulcra are housed on movable nest holder, and the other end of facial bone is articulated in the middle part of fulcra, and the shortcoming of this structure is, strutting comparatively of umbrella required great effort, and facial bone can not really contact with umbrella cover, and umbrella does not have umbrella frame to support under the umbrella cover at place, umbrella top after propping up, make the umbrella cover profile loose, the support strength of umbrella stand is relatively poor.A kind of umbrella frame structure preferably is that to change said structure into facial bone longer, and fulcra are shorter, and the other end of fulcra is articulated in the middle part of facial bone, and facial bone can be contacted with umbrella cover when umbrella opens, and makes the umbrella cover tensioning, appearance looks elegant, and support strength improves.But the shortcoming of this structure is the fulcra opening part of U-shaped easily injures staff when the opening and closing of umbrella.

The purpose of this utility model provides a kind of folding umbrella framework, and it can eliminate the shortcoming of above-mentioned umbrella stand, has to strut laborsavingly, and umbrella stand intensity is good, and props up to receive and be difficult for hindering hand, the advantage that umbrella cover is smooth when disturbing.

The purpose of this utility model realizes by following technical scheme.A kind of folding umbrella framework that is difficult for hindering hand, comprise umbrella bar, fixed nest holder, movable nest holder, facial bone and fulcra, fixed nest holder is packed in the top of umbrella bar, movable nest holder is sleeved on the umbrella bar, and facial bone is housed on fixed nest holder, and fulcra are housed on movable nest holder, the cross section of described facial bone and fulcra is U-shaped, it is characterized in that: the hinged middle part that is loaded on facial bone of the other end of described fulcra, with the movable nest holder linkage section on, the opening in the U-shaped cross section on the described fulcra is bundled into the circle of sealing.The new shape of this practicality is adopted into a facial bone and a bone structure in U-shaped cross section, on the hinged fixed nest holder that is contained in umbrella stand upper end of facial bone one end, fulcra one end is hinged on the movable nest holder, the end of fulcra is hinged on the middle part of facial bone, the length of fulcra is short than facial bone, make when strutting laborsaving, owing to the support of facial bone, umbrella cover can be held up when strutting, smooth, the attractive in appearance and intensity increase of umbrella cover, the U-shaped opening of fulcra done being rolled into circle, make this umbrella when opening and closing, can not injure staff.

In sum, the utility model is owing to adopt with fulcra and promote facial bone, and facial bone holds up the form of umbrella cover, at the U-shaped opening section place of fulcra, the U-shaped mouth is changed over the circle of sealing, makes it can not hinder hand and makes umbrella cover smooth attractive in appearance and intensity good.The utility model is suitable for using on the various parachute kits.
