Description

A kind of nest body umbrella rib structure of loose-leaf system

Technical field

The utility model relates to a kind of umbrella rib structure, especially need not to tie up, need not riveted joint, a kind of loose-leaf system nest body umbrella rib structure that adopts loose-leaf system connected mode that cover colludes that up-down runner body and umbrella frame are linked up.

Background technology

Umbrella is an indispensable daily necessities during we live, and the kind of umbrella is a lot, and wherein the version of umbrella frame is also very abundant, but is this structure of rivet that adopts wire binding mostly on the market, seldom adopts this form of loose-leaf system.

As the patent No. is 92244154.5 1 kinds of simply-assembled umbrella nest umbrella rib structures, what adopt is a kind of loose-leaf system form, this structure assembling is easy, manufacturing cost is low relatively, use also reliable, the vestibule that its nest seat has a plurality of side channels and the cross section that communicates with it is rectangle substantially, one end of umbrella frame is designed to T shape, when packing into the rotating shaft of T shape end along its vertically from side channel insert vestibule and in vestibule half-twist become laterally to place and get final product, the rectangle pin insertion vestibule of the relative set that nest is covered limits the umbrella frame rotating shaft then, the nest lid that utilizes the nest lid will be provided with in pairs accordingly with the elasticity of plastics distortion of the zigzag ring gear that matches of nest seat does not releasably combine securely with the nest seat, umbrella frame can only be rotated and play up and down after assembling, realize umbrella frame folding umbrella and can not coming off freely.

Summary of the invention

The purpose of this utility model is to adopt punching to wear the problem of the complicated technology of steel wire mostly in order to solve traditional umbrella rib structure up-down runner, providing a kind of employing not have the no steel wire perforation of riveted joint ties up, simple and easy, practical, cost is low, utilizes hook-type cutting ferrule mode to connect a kind of loose-leaf system nest body umbrella rib structure of umbrella frame.

The technical scheme that its technical problem that solves the utility model adopts is: this loose-leaf system nest body umbrella rib structure, comprise nest, following nest, umbrella frame, umbrella bar, following nest comprises nest lid and nest seat, the nest seat is provided with torus, one end cover of hook colludes on the nest seat, the other end and the umbrella frame of hook join, after the hook cover colludes on the nest seat, the nest lid is pressed onto on the nest seat, nest covers that to be provided with notch corresponding with hook, hook is the center of circle together with umbrella frame to collude the heart, rotates as loose-leaf system, thereby realizes parachute-opening and the nest purpose that closes one's umbrella.

As preferably, described nest covers and is provided with through hole, the aperture cooperates with the external diameter of umbrella bar, following nest slides on the umbrella bar, then through hole and umbrella bar adopt matched in clearance on it, be provided with several locating holes between last through hole and the interior ring, as two, ring is for circular, when nest seat stand cylinder also is circular in the nest lid, locating hole will guarantee can not rotate between nest lid and the nest seat, the outer shroud circumference of nest lid is provided with several notches, and the width of notch is bigger than the appearance and size of hook, when hook is moved up and down, can not be stuck, the length of notch guarantees that hook moves up and down maximum displacement and gets final product.

As preferably, described nest seat is to be provided with the important actor body on a base plate, the overall dimensions of important actor body cooperate with the interior hole dimension of ring in the nest lid, endoporus as ring in the nest lid is interior hexagon, then the important actor body is outer hexagon, adopt interference fit between them, the axial centre of nest seat is provided with lower through-hole, and the endoporus of lower through-hole cooperates with the external diameter of umbrella bar, and is same, as following nest, keep matched in clearance between lower through-hole and the umbrella bar, an end of important actor body is provided with several alignment pins, alignment pin and locating hole interference fit, this alignment pin equally also adopts when the important actor body is circle, polygon can not established, and torus is arranged on the outer ring of base plate, is provided with several ring through holes between torus and the important actor body, the quantity of the notch in quantity and the nest lid of ring through hole equates, generally is provided with 6 to 8 in the umbrella.

As preferably, the heart that colludes of described hook is circle, its round diameter and toric external diameter are matched in clearance, hook to collude mouthful size littler than toric external diameter, hook be have necessarily flexible, after the hook cutting ferrule is gone into torus, the colluding of hook mouthful just hindered hook and deviate from, and the appearance and size of hook will guarantee the intensity of umbrella frame certainly, is axially arranged with blind hole in the straight-bar district of hook, connect with umbrella frame, be used for injection moulding or injecting glue.

As preferably, described upper runner structure is identical with following nest structure, and the up-down runner in umbrella above-below direction when mounted is just opposite, and its structure is also identical.

As preferably, nest lid, nest seat, hook all are one-time formed.

Therefore, the utility model is a reasonable in design, and it is simple to make assembling, attractive in appearance, adopts the circular hinges form, uses dexterous a kind of loose-leaf system nest body umbrella rib structure.
