Description

Automatic umbrella rib frame

Technical field

The utility model relates to parachute kit used in everyday, relates in particular to the rim structure of umbrella of automatic umbrella, can be used for straight rib self-opening umbrella or rolls over automatic umbrella more.

Background technology

The umbrella frame frame of automatic umbrella of the prior art, the articulated section between each umbrella frame need use rivet that it is mutually combined usually, and this common syndeton is comparatively inconvenience during fabrication; waste time and energy; and uneconomical, combined strength is relatively poor again, and regular meeting causes automatic umbrella to damage when parachute-opening.For this reason, the patent No. is that the Chinese utility model patent of ZL02203359.9 has proposed a kind of improved automatic umbrella rib structure, as shown in Figure 1, its support main bone 2 ' fulcra 1 ' by the body 11 of inboard ' and the cylinder 12 ' fit in the outside form, described elastic support 3 ' taking the shape of the letter U is connected across in the recess of below, body 11 ' outer end, thus fulcra 1 ' with elastic support 3 ' between be connected need not riveted, and can improve its intensity.But also there is following shortcoming in the umbrella frame frame of this structure: 1, with body 11 ' more when taking a lot of work with the fashionable institute of cylinder 12 ' cover; 2, fulcra 1 ' be divided into body 11 ' and cylinder 12 ' two parts have not only increased number of components, have also increased cost.

The utility model content

The technical problems to be solved in the utility model provides the less and easy more umbrella rib frame automatically of assembling of a kind of parts.

The purpose of this utility model can realize by adopting following technical measures, design a kind of automatic umbrella rib frame, when being applied to the automatic umbrella of many foldings, it comprises: middle rod, be fixed in excellent top last nest, with described in the middle nest of excellent slip socket and following nest, inner end respectively with described in the fulcra of nest and the pivot joint of following nest and elastic support and inner end respectively with last nest and the pivot joint of fulcra outer end prop up support bone and coccyx; The outer end of described elastic support and described fulcra flexibly connect, and the outer end of described support bone and fulcra middle part articulate; Described fulcra have contact with the U type outer end of described elastic support and the described overlap joint that has contact with being provided with one with the elastic support junction.

And when being applied to straight rib self-opening umbrella, it comprises: middle rod, be fixed in excellent top last nest, with described in the middle nest of excellent slip socket and following nest, inner end respectively with described in nest and the fulcra of following nest pivot joint and the main bone of elastic support and inner end and the pivot joint of last nest; The outer end of described elastic support and described fulcra flexibly connect, and the outer end of described fulcra is articulated in the middle dish place of described main bone; Described fulcra have contact with the U type end of described elastic support and the described overlap joint that has contact with being provided with one with the elastic support junction.

Described having contact with is located at the fulcra bottom, leave opening between its outer end and the fulcra bottom less than described elastic support diameter, the U type outer end of described elastic support is positioned at the described space that surrounds with the fulcra bottom of having contact with, and just is not easy after elastic support installs like this to break away from and has contact with.

The described outside of having contact with opening part is a guiding surface, and in making things convenient for elastic support to enter during installation to have contact with, and the inboard is a vertical plane, can prevent from that elastic support from skidding off to have contact with.

The inner segment cross section of described fulcra is bigger square of external diameter, and outer section cross section of described fulcra is less I-shaped of external diameter, the described outer end that is fixed on the fulcra inner segment of having contact with.

Compared with prior art, automatic umbrella rib frame of the present utility model has following advantage: described fulcra are a global facility with having contact with, but integrated injection molding has not only reduced number of components, also can reduce production costs, reduce the man-hour that assembling is taken, only need when elastic support is installed to descend nest to press to middle nest, the outer end that makes elastic support is above behind the opening that has contact with, in nest can be got into elastic support and have contact with under loosening, very convenient quick, packaging efficiency can be increased to more than 3 times.

The specific embodiment

The utility model is described in further detail below in conjunction with accompanying drawing.

As Fig. 2 or shown in Figure 3, automatic umbrella rib frame of the present utility model comprises: middle excellent 1, be fixed in excellent 1 top last nest 2, and described in the middle nest 3 of excellent 1 slip socket and following nest 4, inner end nest 3 and following nest 4 articulate respectively and in described fulcra 5 and U type elastic support 6 and be arranged on compression spring 20 between middle nest 3 and the following nest 4.Special feature of the present utility model is: described fulcra 5 with elastic support 6 junctions be provided with an opening outwardly have contact with 51, the U type outer end of described elastic support 6 and described have contact with 51 the overlap joint.

As shown in Figure 4, describedly have contact with 51 and be located at fulcra 5 bottoms, its the inner links to each other with fulcra 5, leave opening between its outer end and fulcra 5 bottoms less than described elastic support 6 diameters, it is described that to have contact with 51 be a guiding surface 511 in the outside of this opening part, the inboard is a vertical plane 512, and the U type outer end of described elastic support 6 is positioned at describedly has contact with 51 and the space that surrounds, fulcra 5 bottoms.

Described fulcra 5 are made up of the internal and

external section

52 and 53 that links to each other, and wherein inner segment 52 cross sections are bigger square of external diameter, and outer section 53 cross sections are less I-shaped of external diameter, and described the inner of 51 of having contact with links to each other with the outer end of fulcra 5 inner segments 52.But the inner segment 52 of described fulcra 5 is with outer section 53 and have contact with 51 integrated injection moldings, has not only reduced number of components, also can reduce cost.

Umbrella frame frame of the present utility model can be applicable to many automatic umbrellas of folding or straight rib self-opening umbrella, when being applied to the automatic umbrella of many foldings, as shown in Figure 2, the umbrella frame that supports umbrella cover comprises a support bone 7 and a coccyx 8, the inner of described support bone 7 and last nest 2 articulate, and outer end and described fulcra 5 middle parts articulate; The inner end of described coccyx 8 then articulates with fulcra 5 outer ends, and also is connected with backguy 9 between the inner of described support bone 7 outer end and coccyx 8.When being applied to straight rib self-opening umbrella, as shown in Figure 3, the umbrella frame that supports umbrella cover is long main bone 10, and these main bone 10 inner and last nests 2 articulate, and the outer end of described fulcra 5 is articulated in middle dish 101 places of this main bone 10.

During assembling, after each nest body, spring 20 and each umbrella frame installed, the inner with elastic support 6 articulates with following nest 4 earlier, then umbrella frame is inverted, is firmly down depressed nest 4, surpass described 51 the outside opening that has contact with until the outer end of described elastic support 6, loosen nest 4 down this moment, the elastic force of spring 20 struts the U type outer end of elastic support 6 to have contact with 51 opening and enter its inner space through having contact with 51 outside guiding surface 511, can finish the assembling of elastic support 6 thus, and is very convenient quick.
