Abstract

The utility model relates to umbrella technology field, in particular is a multi-folding automatic umbrella structure modification. Elastic component pulling handles are arranged between an upper nest and a support bone or between a lower nest and the support bone, corresponding tensile force can be generated by elastic components to pull the lower nest to upwardly move and to finally realize the aim of distracting the umbrella. The utility model effectively simplifies the umbrella structure, assembling thereof is more convenient, machining cost is low, and the support bone is directly provided with the elastic component pulling handles, thus strength of distraction is strengthened, stability is high.

Description

The automatic umbrella structural improvement of many foldings

Technical field:

The utility model relates to the parachute kit technical field, refers in particular to the automatic umbrella structural improvement of a kind of many foldings.

Background technology:

Umbrella can be described as people's daily life and uses quite general product, no matter be fine day or rainy day, all can see people it is brought as sunshade or the apparatus that keeps off the rain.Especially multi-fold umbrella, people use more extensive at present.Include hand and self-action in current many foldings umbrella, wherein umbrella can be realized automatic expansion automatically, and is easy to use; The outer compression spring of rod was realized opening automatically during but existing automatic umbrella only was set in by one, and this compression spring is arranged between nest and the middle nest, and structure is complexity comparatively, processing and assembling inconvenience, production cost height, and the open dynamics deficiency of umbrella frame, easily rock less stable.

Summary of the invention:

The purpose of this utility model is to overcome the defective of prior art, provides a kind of simple in structure, assemble more easy, and the automatic umbrella structural improvement of many foldings that strengthens of the tension force of umbrella frame.

For achieving the above object, rod during the utility model includes nest, nest reaches down, the upper end of rod during last nest is fixedly arranged on, its periphery is articulated with some interior main bones, and following nest pivot bush unit is on middle rod, and its periphery also is articulated with some fulcra, the outer end of fulcra and interior main bone photo articulate, flexible pulls and supports between the lower edge section of last nest and the fulcra, and wherein going up the position that nest lower edge section and elastic component be articulated is a nido structure, the making that is formed in one of this nido structure and last nest.

For achieving the above object, the utility model also can be achieved through the following technical solutions: the lower edge section of following nest, and flexible pulls and supports between the fulcra, and the position of wherein descending nest lower edge section and elastic component to be articulated is a nido structure, the making that is formed in one of this nido structure and last nest.

The utility model has been simplified umbrella structure effectively, assembles more conveniently, and processing cost is low, and fulcra directly flexible pull and support, open dynamics is enhanced, stability is high.

The specific embodiment:

See shown in the accompanying

drawing

1,2 rod 3 during the utility model includes nest 1, nest 2 reaches down, the upper end of rod 3 during last nest 1 is fixedly arranged on, its periphery is articulated with some interior main bones 40, and nest 2 pivot bush units are on middle excellent 3 down, and its periphery also is articulated with some fulcra 5, and the outer end of fulcra 5 and interior main bone 40 are articulated.The lower edge section of last nest 1 is provided with a nido structure 11, the making that is formed in one between nido structure 11 and the last nest 1, and the periphery of nido structure 11 pivot joint plurality of elastic part 6, and the other end of elastic component 6 is connected on the fulcra 5.

During parachute-opening, press the corresponding button on the fixed handle, remove the snap close of nest 2 down; At this moment, under the elastic force effect of elastic component 6, elastic component 6 imposes on the pulling force that fulcra 5 upwards (are gone up nest 1 direction), moves on the rod 3 in nest 2 edges under fulcra 5 drive immediately.Move on the following nest 2 so that fulcra 5 the inners are moved on also, utilize the correlation (constituting a triangle between interior main bone 40, fulcra 5 and the middle rod 3) on each limit of triangle, move the distance that then shortens between itself and the last nest 1 on the following nest 2, launch outward the outer end of fulcra 5 thus, main bone 40 outer opening in promoting simultaneously, and drive other umbrella frame and open, promptly umbrella frame is opened fully, realizes parachute-opening.

After umbrella frame opened, elastic component 6 still gave fulcra 5 certain power that pulls and supports, thereby had strengthened the support force of fulcra 5, and umbrella cover Zhang Degeng is tight, good stability.When closing one's umbrella, the same with existing parachute kit, the nest 2 of leaving behind is down buckled in button until its snap close, and each umbrella frame folds in succession, and the elastic component 6 that pulls and supports between nido structure 11 and fulcra 5 is in extended state, to treat next parachute-opening.

drawing

3,4,5 is used for eighty percent discount, three foldings and four structural representations of rolling on the umbrellas for the utility model; Can realize the purpose of automatic deployment by the effect of elastic component 6, simple in structure, processing and assembling are all very convenient, boost productivity effectively, reduce cost.

Accompanying drawing 6,7 is depicted as another status architecture schematic diagram of the utility model; Include nest 1, down nest 2 and in rod 3, the upper end of rod 3 during last nest 1 is fixedly arranged on, its periphery be articulated with some in main bones 40, and following nest 2 pivot bush units are on middle excellent 3, its periphery also is articulated with some fulcra 5, the outer end of fulcra 5 and interior main bone 40 are articulated.The lower edge section of following nest 2 is provided with a nido structure 21, making is formed in one between nido structure 21 and the last nest 2, and the periphery of nido structure 21 articulates plurality of elastic part 6 (in the present embodiment for the ease of closing one's umbrella, the end that elastic component 6 connects nido structure 21 sets firmly a connecting rod 61, be articulated on the nido structure 21 by connecting rod 61 again), the other end of elastic component 6 is connected on the fulcra 5.

During parachute-opening, press the corresponding button on the fixed handle, remove the snap close of nest 2 down; Because the elastic component 6 that is connected between nido structure 21 and the fulcra 5 is in extended state, its two link all has towards the stage casing and reels trend, so that nido structure 21 is moved on the rod 3 in 21 edges of following nest 2 and nido structure together with descending nest 2 to be subjected to the pulling force that makes progress from elastic component 6.Move on the following nest 2 so that fulcra 5 the inners are moved on also, utilize the correlation (constituting a triangle between interior main bone 40, fulcra 5 and the middle rod 3) on each limit of triangle, move the distance that then shortens between itself and the last nest 1 on the following nest 2, launch outward the outer end of fulcra 5 thus, main bone 40 outer opening in promoting simultaneously, and drive other umbrella frame and open, promptly umbrella frame is opened fully, realizes parachute-opening.
