Abstract

The utility model relates to an automatic folding umbrella structure. The automatic folding umbrella structure is composed of an umbrella surface, an umbrella frame, an umbrella handle, an umbrella grip and an automatic stretching device. The automatic folding umbrella structure is characterized in that a common round umbrella surface is changed into an octagonal umbrella surface, the octagon is a round inscribed octagon, and the distances between the center and all the top points of the octagon are equal. The umbrella frame is a three-fold umbrella frame, six metal rods constitute a connection rod mechanism, two parallelograms and one triangle are formed inside the connection rod mechanism, each main stress rod on the outer side is supported by other two short rods, and the section of each metal rod is rectangular. The automatic folding umbrella structure improves structural strength, bend resistance and using comfort.

Description

New type auto folded umbrella structure

Technical field

The utility model relates to the parachute kit technical field, especially relates to a kind of new type auto folded umbrella structure.

Background technology

Parachute kit has become most people go on a journey when rainy day or Exposure to Sunlight indispensable instrument.For easy to carry, folded umbrella miscellaneous has appearred in existing market, yet many problems have all appearred in these umbrellas in practical process, as launch inconvenience, and structural strength is inadequate, and while meeting strong wind, easy flexural deformation even fractures, and the most of circle that adopts of umbrella cover, easily drench with rain in people's shoulder both sides in use, and rain-proof effect is poor, and these problems have a strong impact on the practical function of current folded umbrella.

Summary of the invention

In order to solve folded umbrella, launch inconvenience, the problem such as rain-proof effect is poor, and structural strength is inadequate, the utility model provides a kind of new type auto folded umbrella structure, for existing structure, has carried out rational improvement.

The technical scheme that its technical problem that solves the utility model adopts is: a kind of automatic folding umbrella structure consists of umbrella cover, umbrella frame, umbrella handle, handle of umbrella and self-presenting devices.

Described umbrella cover changes general circular umbrella cover into the octagon umbrella cover.This octagon, in circle, connecing octagon, has met center equal to the distance on each summit of octagon simultaneously, thereby has guaranteed the uniformity of eight rim structure of umbrella sizes that provide support.

Described umbrella frame is the triple folding umbrella bone, by six roots of sensation Metallic rod, forms a linkage, inner two parallelogram and triangle of forming, and outside main stress bar has two other quarter butt to support, and wherein the Metallic rod cross section is rectangle.

Described umbrella handle consists of the hollow octagon Metallic rod of two-stage, and is corresponding with umbrella shape, avoided skeleton and umbrella cover relatively rotating on umbrella handle.

Described handle of umbrella consists of internal layer rigid plastics and outer soft rubber material, and cross section is the shape after the octagon chamfering corresponding with umbrella cover.

Described self-presenting devices consists of spring, tooth bar, gear, umbrella handle sleeve pipe internal tooth, by pinion and rack, controls moving up and down of umbrella handle sleeve pipe, realizes the expansion of umbrella cover and folds.

With existing umbrella structure, compare, of the present utility modelly be a little: the utility model can Automatic-expanding, has greatly improved the overall construction intensity of rain-proof effect and the umbrella of umbrella, have stronger counter-bending, deformability, simultaneously simple in structure, novel and beautiful appearance, good hand touch, be easy to manufacture.

The accompanying drawing explanation

Below in conjunction with accompanying drawing, the utility model is further illustrated.

Fig. 1 is the umbrella cover structure figure of the utility model folded umbrella.

Fig. 2 is folded umbrella cut-away view while launching fully.

Fig. 3 is folded umbrella partial enlarged drawing while launching fully.

Fig. 4 is the cut-away view that folded umbrella folds.

Fig. 5 is the partial enlarged drawing that folded umbrella folds.

Fig. 6 is folded umbrella overall structure figure.

The specific embodiment

In Fig. 1, umbrella cover is the octagon umbrella cover, with the cross sectional shape of human body, matches, and this shape hides the area that has increased the two sides of umbrella under the suitable prerequisite of rain area before and after guaranteeing.This octagon, in circle, connecing octagon, has met center equal to the distance on each summit of octagon simultaneously, thereby has guaranteed the uniformity of eight rim structure of umbrella sizes that provide support, and manufactures easy to assembly.

in embodiment illustrated in fig. 2, the utility model automatic folding umbrella is in complete deployed condition, it comprises spring 1, umbrella handle sleeve pipe 2, one-level umbrella handle 3, secondary umbrella handle 4, fixture 5, handle of umbrella 6, tooth bar 7, pinion 8, resilient key 9, parachute-opening button 10 and the umbrella frame that is formed by six roots of sensation Metallic rod, wherein there is the rack structure of two symmetries umbrella handle sleeve pipe 2 inboards, tooth bar 7 is hinged by resilient key 9 with secondary umbrella handle 4, Metallic rod 13 is hinged with one-level umbrella handle 3 upper ends,

Metallic rod

11, 12 is hinged with umbrella handle sleeve pipe 2, between six roots of sensation Metallic rod, by form shown in Figure 2, be hinged.Under deployed condition, spring 1 is shifted tooth bar 7 onto position shown in Figure 2, and resilient key 9 snaps in the aperture of one-level umbrella handle 3 ends simultaneously, and

umbrella handle

3,4 positions are fixed, and realize that the integral body under deployed condition is fixed.

Press resilient key 9;

umbrella handle

3,4 separates; only need one and hold one-level umbrella handle end; utilize health that secondary umbrella handle 4 is pushed in one-level umbrella handle 3, with hour rack 7, rise, and drive umbrella handle sleeve pipe 2 inboard tooth bars by pinion 8; umbrella handle sleeve pipe 2 is moved downward; and

Metallic rod

11,12 is drop-down, thus realize folding of umbrella cover, until reach complete collapse state.

In the embodiment shown in fig. 4, folded umbrella is in collapse state, and this moment, spring 1 was in the most compressed state to it of tooth bar 7, and the end aperture of one-level umbrella handle 3 snaps on the fixture 5 that is positioned at handle of umbrella 6 upper ends, realizes fixing under collapse state.

After pressing parachute-opening button 10, one-level umbrella handle 3 separates with handle of umbrella 6, spring 1 promotes tooth bar 7 downwards, it is protruding that tooth bar 7 promotes secondary umbrella handle 4, with hour rack 7, when moving downward, by pinion 8, drive umbrella handle sleeve pipe 2 inboard tooth bars, promote umbrella handle sleeve pipe 2 and move upward, umbrella handle sleeve pipe 2 promotes

Metallic rod

11,12 and moves upward in the process that moves upward, thereby realize the Automatic-expanding of umbrella cover, until reach complete deployed condition.
