Abstract

A multi-folding umbrella windbreaking frame comprises a main channel frame (1), the front end part of which is connected with the upper nest of an umbrella, a short channel frame (2), the front end part of which is connected with the lower nest of the umbrella, the back end part of which is articulated with the cross hole (11) in the middle of the main channel frame (1) by a pin (5), and a draught spring (7), one end of which is fixed in the front of the connection point between the main channel frame (1) and the short channel frame (2), while the other end of the draught spring (7) is connected with the pin (5); the cross hole (11) takes a shape of a long strip, and the pin (5) under the cooperation of the power of wind and the draught spring (7) can slip along the long direction of long strip cross hole (11). The structure offers a buffering activity space when the umbrella frame is everted owing to suffering the strong wind from the end to the top, so as to avoid the frame from being damaged; therefore, the utility model has good windbreaking effect.

Description

The wind-proof umbrella skeleton of many folding umbrellas

Technical field

The utility model relates to a kind of skeleton of en-toutcas, relates in particular to a kind of structure-improved of many folding umbrella frame framves.

Background technology

Existing many folding umbrellas, do the time spent at the wind-force that is subjected to from bottom to up, be used to resist wind-force thereby also be that the position of stressed maximum is a main trough frame and the tie point place of short groove bone, existing many folding umbrella bones generally are by being connected in the windproof backguy of short groove bone rear end and elephant head-like groove rib front end, or utilize the elasticity of elasticity umbrella frame such as fiber bone itself to reach windproof purpose, but its effect is all undesirable, reason is that the position of main trough frame and the tie point of short groove bone is changeless in the above-mentioned umbrella rib structure, even elasticity umbrella frame, its movable leeway is also minimum, when umbrella frame was subjected to the high wind effect and turns up suddenly, umbrella frame tended to damage because of bending by force.

Summary of the invention

The technical problems to be solved in the utility model provides a kind of wind-proof umbrella skeleton that many foldings umbrella of buffering activity space can be provided when umbrella frame turns up.

The purpose of this utility model can realize by adopting following technical measures, designs a kind of wind-proof umbrella skeleton of many folding umbrellas, comprising: the main trough frame that flexibly connects successively and short groove bone, elephant head-like groove rib and coccyx from the inside to the outside; The leading section of described main trough frame and short groove bone articulates with the upper and lower nest that is socketed on the middle rod respectively, the rear end of short groove bone rear portion joint is articulated in the through hole at main trough frame middle part by a bearing pin, and the middle part of described joint is connected in the elephant head-like groove rib leading section by a windproof backguy; The utility model wind-proof umbrella skeleton also comprises a tension spring in addition, and an end of this tension spring is fixed on the main trough frame front end with short groove bone tie point, and the other end is connected with bearing pin; Described through hole is the strip hole, and described bearing pin can slidably reciprocate along the length direction of this strip through hole.

At the normal operating condition of umbrella, described bearing pin is subjected to the pulling force spring action to be positioned at the inner terminal of described through hole; The effect of wind-engaging power, umbrella cover drive umbrella frame and turn up, and main trough frame moves on the nest down by short groove bone pulling, and following nest further promotes the outermost end that the joint of short groove bone and pulling force that bearing pin overcomes tension spring thereof move to through hole again.Said structure makes the main trough frame and the tie point of short groove bone have certain activity space, plays the effect of buffering when umbrella frame turns up.

Compared with prior art, the wind-proof umbrella skeleton of many folding umbrellas of the present utility model has following advantage: can make many folding umbrellas in the effect of wind-engaging power, umbrella cover drives the activity space that a buffering is arranged when umbrella frame turns up, and prevents that therefore the umbrella frame frame from damaging, and has protection effect preferably.

Description of drawings

The drawing of accompanying drawing is described as follows:

Fig. 1 is the structural representation that the utility model is rolled over the wind-proof umbrella skeleton of umbrella more;

Fig. 2 is the exploded view of described short groove bone 2 ends and main trough frame 1 junction.

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

The specific embodiment

As shown in Figure 1, the utility model wind-proof umbrella skeleton of rolling over umbrella comprises more: the main trough frame 1 that flexibly connects successively from the inside to the outside and short groove bone 2, elephant head-like groove rib 3 and coccyx 4.The leading section of described main trough frame 1 and short groove bone 2 articulates with the upper and lower nest that is socketed on the middle rod 8 respectively, the rear end of short groove bone 2 rear portion joints 21 is articulated in through hole 11 places at main trough frame 1 middle part by a bearing pin 5, and the middle part of described joint 21 is connected in elephant head-like groove rib 3 leading sections by a windproof backguy 6; Special feature of the present utility model is also to comprise a tension spring 7, and an end of this tension spring 7 is fixed on the main trough frame 1 front end with short groove bone 2 tie points, and the other end is connected with bearing pin 5.As shown in Figure 2, described through hole 11 is the elliptical aperture of strip, and described bearing pin 5 can slidably reciprocate along the length direction of this strip through hole 11, but no matter bearing pin 5 is positioned at which end of through hole 11, this tension spring 7 all keeps the state of elongation always.

Under the normal operating condition of umbrella, described bearing pin 5 is subjected to tension spring 7 pulling force effects to be positioned at the inner terminal of described through hole 11; When the effect of wind-engaging power, when umbrella cover drive umbrella frame turned up, main trough frame 1 moved on the nest 9 down by short groove bone 2 pullings, and the pulling force that the joint 21 of the short groove bone 2 of the further again promotion of following nest 9 and bearing pin 5 thereof overcome tension spring 7 moves to the outermost end of through hole 11.Said structure has cushioned wind-force significantly to the umbrella frame destructive power of main trough frame particularly, and tension spring 7 also helps umbrella frame from the state homing of turning up except that the effect that can produce certain opposing wind-force.

As Fig. 2, the length direction of described ellipse hole 11 is positioned on the extension line of tension spring 7, and it is more smooth and easy that bearing pin 5 is slided on through hole 11, reduces the wearing and tearing of 5 pairs of umbrella frames of bearing pin.

As shown in Figure 2, described tension spring 7 is connected with bearing pin 5 by the laminar little hook 71 in tape spool hole, a rear end, the crotch clasp joint of described little hook 71 front ends is in tension spring 7 rear ends, the described bearing pin 5 of cross-under in the axis hole of its rear end, thereby short groove bone 2 and bearing pin 5 thereof can freely rotate relative to tension spring 7.
