Abstract

A reinforced-typed multi-folding umbrella plastic fluted rib comprises a main fluted rib (1), an elephant-head groove (2), a short fluted rib (4) and a connecting rod (5) and a fiber rib (3) that is movably hinged with the elephant-head groove (2). A lifting convex post (8) is arranged at the middle part of the elephant-head groove (2); a pull thread (6) is passed through a small hole arranged on the upper part of the lifting convex post (8). When the plastic fluted rib is unfolded or folded up, the lifting convex post (8) is projected outside the elephant-head groove (2) under the drawing of the pull thread (6) to reduce the arc of the pull thread (6) and reduce the friction when unfolding or folding up the umbrella; when the plastic fluted rib is folded, the lifting convex post (8) is sunk into the elephant-head groove (2) under the pressure of the main fluted rib (1); the main fluted rib (1) is paralleled and jointed with the elephant-head groove (2) to reduce the storage volume of the umbrella.

Description

The plastic cement groove bone that is used for many folding umbrellas

Technical field

The utility model relates to a kind of en-toutcas, relates in particular to a kind of plastic cement groove bone that is used to support many folding umbrella umbrella covers.

Background technology

The existing plastic cement groove bone that is used for many folding umbrellas, between main trough frame front end and fiber bone rearward end, all must flexibly connect a backguy, this backguy also must be passed and be resembled a spacing hole at groove middle part, to maintain the folder function of groove osseous system, our test shows that resembling a folding result of use of the whether rational in infrastructure and groove osseous system of groove middle part spacing hole has very big relation.Existing plastic cement groove bone adopts two kinds of schemes in design during as groove middle part spacing hole, and the one, encase and be fixed on the hole of passing through of the stage casing of a groove with the formation backguy with iron sheet; It two is to allow backguy directly pass from the bottom land that resembles a groove, no matter that a kind of scheme, it is changeless resembling a height of groove middle part spacing hole, can produce the problem of two aspects like this, the one, and the radian of backguy is excessive, has increased that the groove bone opens or the frictional force when folding; The 2nd, groove bone main trough frame and resemble a groove and can not well fit together when full folded state can increase the volume of umbrella when the folding storage state like this.

Summary of the invention

The purpose of this utility model is to avoid the deficiencies in the prior art part and provides a kind of smooth opening and closing, folding storage volume the less plastic cement groove bones that are used for many folding umbrellas.

The purpose of this utility model can realize by adopting following technical measures, design a kind of plastic cement groove bone that is used for many folding umbrellas, comprise: main trough frame, resemble a groove and fiber bone, resemble a groove and the fiber bone is movably hinged by joint, main trough frame, resemble the supporting construction that a groove, short groove bone and connecting rod are formed the bolt cam posture.The middle part that wherein resembles a groove also is provided with a lifting projection, and the top of this lifting projection has an aperture, and this aperture is passed in backguy, and its two ends flexibly connect with the end of joint and main trough frame respectively; Plastic cement groove bone open or the process that folds in, the lifting projection is subjected to that the backguy traction is outstanding to resemble outside the groove, the radian of backguy thereby diminish, thereby reduced the friction that umbrella opens or backguy is slided and produced when folding; When plastic cement groove bone was in full folded state, the lifting projection was sunk to by main trough frame compressing to resemble in the groove, main trough frame with resemble the parallel applying of a groove, thereby reduced the collection volume of folded umbrella.

Compared with prior art, the plastic cement groove bones that the utility model is used for many folding umbrellas have following advantage: the groove bone open or the frictional force when superimposed less, thereby make the folding of groove bone more smooth and easy, more durable; The folding storage volume of groove bone is less, is convenient to carrying of umbrella.

Description of drawings

The drawing of accompanying drawing is described as follows:

Fig. 1 is the structural representation that the utility model is used for the plastic cement groove bone of many folding umbrellas;

Fig. 2 resembles the lifting projection at a groove 2 middle parts and the partial enlarged drawing of pedestal thereof among Fig. 1;

Fig. 3 is the decomposing state schematic diagram of described main trough frame 1.

The utility model is described in further detail below in conjunction with drawings and Examples.

The specific embodiment

As shown in Figure 1, the plastic cement groove bones that the utility model is used for many folding umbrellas comprise: main trough frame 1, resemble a groove 2 and fiber bone 3, resemble a groove 2 and fiber bone 3 is movably hinged by joint 7, main trough frame 1, resemble the supporting construction that a groove 2, short groove bone 4 and connecting rod 5 are formed the bolt cam postures.It is that a lifting projection 8 is set at the middle part that resembles a groove 2 that the utility model is different from the prior art part, this lifting projection 8 is the up-small and down-big stepped cylinder of two-stage, its top has an aperture 81, this aperture 81 is passed in backguy 6, and its two ends flexibly connect with the end of joint 7 and main trough frame 1 respectively; Correspondingly, at a described groove 2 middle parts that resemble the pedestal 21 that can hold and allow lifting projection 8 sink-floats is set, this pedestal 21 has up-small and down-big two-stage ladder hole, the diameter of top aperture is bigger slightly than the diameter of lifting projection 8 top small columns 83, but diameter less than lifting projection 8 bottom limited caps 82, and bottom macropore height is greater than the height of lifting projection 8 bottom limited caps 82, as shown in Figure 2.Owing to adopted said structure, plastic cement groove bone open or the process that folds in, lifting projection 8 is drawn out by backguy 6 tractions, till its limited cap 82 is subjected to pedestal 21 top apertures to stop the place, change rank that is stuck in big aperture, the lifting this moment projection 8 an outstanding groove 2 outer certain altitudes that resemble, this highly is exactly the discrepancy in elevation between pedestal 21 bottom macropores and the lifting projection 8 bottom limited caps 82, because the fixed-site at backguy 6 two ends is constant, the rising of lifting projection 8 will make the radian of backguy 6 diminish, thereby reduce the friction that umbrella opens or backguy 6 is slided and produced when folding.When plastic cement groove bone was in complete folding collecting state, lifting projection 8 was sunk to together with the backguy 6 at this position by main trough frame 1 compressing to resemble in the groove 2, main trough frame 1 with resemble a groove 2 parallel applyings, thereby reduced the folding storage volume of folded umbrella.

In addition, main trough frame 1 and the position that is connected with short groove bone 4 thereof are the positions of bearing umbrella cover pressure maximum, because plastic cement groove bone can not be done too thickly, thereby can produce the problem of insufficient strength, we often can see the existing folded umbrella of plastic cement groove bone that uses when umbrella struts, main trough frame 1 is camber line shape too greatly because of bearing pressure, has influenced the outward appearance of umbrella, and damages easily.The utility model has also been done improvement to this, its measure is to strengthen metal trough 11 in the inner chamber embedding one of described main trough frame 1, and this reinforcement metal trough 11 is close to the inner surface of main trough frame 1, as shown in Figure 3.
