Abstract

The utility model relates to a multi-folding umbrella rib, comprising a main rib, a clip rib, a short rib, a support rib, a long rib and a pull wire, wherein the short rib is articulated between the main rib and the clip rib; the support rib and the pull wire are all articulated between the main rib and the long rib; a movable plastic jacket is put on the support rib, and is fixedly connected with the pull wire. The utility model adds a plastic jacket structure that can move along the support rib to fix the pull wire that ensures coupling of the support rib, and then the pull wire can extend or retreat following the plastic jacket that slides along the support rib to reduce abrasion of the pull wire and the support rib, and to make sure the pull wire does not deviate from the support rib when the umbrella is shut; therefore, the utility model can effectively ensure the smooth shutting of umbrellas, with excellent robustness.

Description

Many folding umbrella frame framves

Technical field

The utility model relates to the parachute kit art, is meant a kind of many folding umbrella frame framves especially.

Background technology

Folded umbrella is because of its collection, carrying convenience, so liked by people; The umbrella frame frame of traditional folded umbrella comprises main bone, splenial bone, short bone, fulcra and long bone, wherein, this long bone is not controlled by main bone, therefore when parachute-opening, long bone can't stretch automatically, and must artificially each root long bone be bent downwards earlier, carry out the parachute-opening action again, otherwise umbrella cover can't strut smoothly; Otherwise, also be that so long bone and fulcra keep same straight line when closing one's umbrella, and must artificially bend long bone, could fully umbrella be packed up, so it is loaded down with trivial details to operate, be unfavorable for that people use.

As shown in Figure 1, Chinese patent 200320118470.5 discloses a kind of many foldings umbrella frame frame that turns up, and it comprises elongated slot 1 ', short groove 2 ', short bone 3 ', major trough 4 ' and long bone 5 ', and is connected by a umbrella frame joint 6 ' between major trough 1 ' and long bone 5 '; It also comprises a backguy 7 ', and this backguy ' one end is articulated on the elongated slot 1 ', and the other end then is articulated on the pivoted hole of umbrella frame joint 6 ' one side; Its setting by this backguy 7 ' is being opened when closing one's umbrella elongated slot 1 ', driving on the one hand major trough 1 ' stretches it or bounces back, then drive backguy 7 ' on the one hand, and backguy 7 ' drives umbrella frame joint 6 ' again, and then drive long bone 5 ', long bone 5 ' is outwards stretched or upwards turn up, thereby reach the purpose that whole umbrella frame frame interlock is opened receipts; But, because of there not being corresponding interlinked mechanism, under permanent the use, usually having loosening sensation between this backguy 7 ' and the major trough 4 ', sometimes even stuck phenomenon takes place.

Again as shown in Figure 2, TOHKEMY 2006-21026 provides a kind of folding umbrella structure, wherein, bag is known umbrella bar 10 ', main bone 20 ', splenial bone 30 ', short bone 40 ', fulcra 50 ' and backguy 60 ', long bone 70 ', utilize the hook 61 ' of this backguy 60 ' directly to collude in fulcra 30 ' upward firm to interfere, thereby reach interlock and open the fruit of producing effects, yet, this backguy 60 ' is metal material with fulcra 30 ', the permanent use under the situation can produce the phenomenon of getting rusty because of mutual wearing and tearing, cause subsequent operation to have some setbacks, bring inconvenience to use.

The utility model content

The utility model is at the existing disappearance of above-mentioned located by prior art, and main purpose is to provide a kind of folding smooth and easy, many foldings umbrella frame frame that steadiness is good.

For realizing above-mentioned purpose, the utility model is taked following technical scheme:

A kind of many folding umbrella frame framves, comprise main bone, splenial bone, short bone, fulcra, long bone and backguy, this short bone is articulated between main bone and the splenial bone, and these fulcra, backguy all articulate between main bone and the long bone, wherein be socketed with a movable plastic chuck on these fulcra, this plastic cement chuck and backguy are affixed.

This backguy middle section position is bent with a coupling hole, and this plastic cement chuck is provided with perforation, and it is affixed to wear a riveting button between this coupling hole and perforation.

This plastic cement chuck is " recessed " font.The sidewall formation that this plastic cement chuck has base portion and stretches along the base portion both sides, this perforation correspondence is arranged on the sidewall.

The utility model is compared with located by prior art, its beneficial effect is can come the affixed above-mentioned backguy that guarantees that the fulcra interlock is used of being used to along the plastic cement of fulcra activity is jacket structured by setting up one, make backguy slide and stretch or shrink along fulcra according to the plastic cement chuck, guarantee can not depart from fulcra when backguy, fulcra reduce wearing and tearing and folding, thereby it is smooth and easy also just to reach folding effectively, the effect that steadiness is good.
