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.

Background technology:

As shown in Figure 1, at present the multi-fold umbrella that uses of people wherein rod 01 forms by the multistage body, be nested connection between each body, the caliber minimum of the body of going up most manages 011 in being commonly referred to as, fixedly connected with last nest 02 in the upper end of interior pipe 011.When parachute kit is opened, in order to hold down nest 03, normally a umbrella is set and buckles 04 in the appropriate position of interior pipe 011 so that strut parachute kit, corresponding umbrella is buckled 04 and is provided with a perforate 0111 buckles 04 installing for umbrella on interior pipe 011.To descend nest 03 upwards to pass to buckle 04 top during parachute-opening, and make umbrella buckle 04 and withstand down nest 03 bottom to umbrella; The user pushes umbrella again and buckles 04 when closing one's umbrella, and makes in its perforate 0111 by interior pipe 011 to contract, and can make down nest 03 to lower slider.This parachute kit parachute-opening fastening structure, its umbrella buckle 04 be installed in the rod 01 within the pipe 011 in, though can reach the effect of parachute kit parachute-opening fastening, but because of interior pipe 011 caliber own less, bad processing punching press umbrella is buckled perforate 0111, and offers perforate 0111 on interior pipe 011, pipe 011 undercapacity in easily making, stress is concentrated, and interior pipe 011 becomes more fragile.When in the driving rain angel time spent, perforate 0111 place of interior pipe 011 is bent, and, make its tube wall easily produce oxidation and rusting, and then manage 011 fracture in easily taking place and lose because of interior pipe 011 has perforate 0111.

Summary of the invention:

The purpose of this utility model is to overcome the defective of prior art and provides a kind of and do not need to install on inner pipe umbrella and buckle, and the intensity of rod in the assurance is used safer parachute kit parachute-opening fastening structure, and is not only simple in structure, be easy to process, and longer service life.

The utility model is achieved by the following technical solution: the lateral margin place at last nest is provided with a lug boss, be provided with elastomer in the lug boss and umbrella is buckled, elastomer is supported in umbrella and buckles, umbrella is buckled an end and is down extended by the lug boss of last nest, and this elongated end is provided with and colludes tooth and cooperate with the catching groove of following nest corresponding position.

Described catching groove is a through hole of establishing in the lug boss of nest lateral margin down, end entrance is horn-like on it, also laterally be provided with a groove on the lug boss of following nest, bottom portion of groove and through hole are connected, one ties up a wiring part of establishing fulcra is embedded in the groove, and umbrella is buckled colludes tooth and embed the lower bottom part that can be fastened on the wiring downside behind the catching groove or be fastened on catching groove; Catching groove below also is provided with a pressing tablet, and pressing tablet is fixed on down nest, and the inboard shape of pressing tablet and umbrella are detained to hold and be complementary.

Described elastomer is a compression spring, and it is arranged at the inboard that umbrella is buckled, and an end is supported in nest, and the other end is supported in umbrella and buckles.

After adopting such structure; buckle to cooperate and to realize that parachute kit opens and uses by being arranged at umbrella on the nest lateral margin with the catching groove of following nest; not needing to offer on pipe within the middle rod perforate buckles with the installing umbrella; not only simplified processing; be beneficial to the raising of productivity ratio; and guaranteed the intensity of middle rod, and make parachute kit use normalization, prolong the service life of parachute kit.
