Description

Parachute kit parachute-opening fastening structure

Technical field:

The utility model relates to the parachute kit technical field, refers in particular to a kind of parachute kit parachute-opening fastening structure of firm umbrella rod when being used for the multi-fold umbrella parachute-opening.

Background technology:

On market, selling parachute kit miscellaneous at present, a folding parachute kit is being arranged, multi-fold umbrella is also being arranged.Multi-fold umbrella particularly, because it has collapsible placement and convenient carrying, thereby current user is more.Yet, though reaching, multi-fold umbrella dwindles the umbrella body, the convenient effect of collection is arranged, and because of its umbrella rod is many foldings form, so form in several sections excellent pipes of umbrella rod, outmost rod pipe caliber maximum is in innermost rod pipe caliber minimum.When opening parachute kit, because down the aperture of nest endoporus is also bigger than the caliber of big stick-means of intimidation pipe, thereby the interior pipe of caliber minimum cooperates meeting to produce big space with following nest endoporus, make the umbrella rod in following nest endoporus, be easy to generate and rock deflection, so the parachute-opening on the umbrella rod buckle and following nest between supporting surface uncertain, the parachute-opening button can't support down nest really, nest slippage downwards easily under making, thus can't reach the purpose that parachute-opening is used.

Summary of the invention:

The purpose of this utility model is to overcome the defective of prior art and parachute kit parachute-opening fastening structure that a kind of firmly umbrella rod is provided.

The utility model is achieved by the following technical solution: parachute kit parachute-opening fastening structure includes nest, following nest, the umbrella rod, interior main bone, fulcra, parachute-opening button and outer main bone, last nest is fixedlyed connected with an end of umbrella rod, the endoporus that the umbrella rod passes down nest is slidingly connected with following nest, one end of interior main bone and last nest articulate, the other end is articulated in the middle part of fulcra, fulcra can be " U " the shape body of rod or the entity body of rod, one end of fulcra articulates with following nest, the other end and outer main bone articulate, outer main bone supports umbrella cover, be provided with radial direction through hole at following nest with the fulcra junction, the fulcra link is provided with the extension nose bar, extending nose bar and fulcra can be one-body molded or be connected by hinge etc., extend the suitable umbrella rod that supports in the endoporus that radial direction through hole that nose bar passes down nest stretches into down nest, make the umbrella rod can arbitrarily not rock deflection in the nest endoporus down, the parachute-opening on the umbrella rod is buckled and can be supported down nest preferably; Stretching the end end face that nose bar stretches into down the nest endoporus is cambered surface, extends nose bar and can be provided with one or two or many Heavenly Stems and Earthly Branches and be separately positioned on the different fulcra, cooperates to extend nose bar and also be provided with corresponding radial direction through hole on the nest down.

After adopting such structure,, fulcra support the umbrella rod because being provided with to extend nose bar and stretch into down the nest endoporus, thereby the umbrella rod phenomenon that in descending the nest endoporus, can not occur rocking arbitrarily, the parachute-opening button can well support down nest, is beneficial to parachute kit and opens and uses.The utility model is simple in structure, easy to use.
