Description

A kind of automatic umbrella folding and unfolding structure

Technical field

The utility model relates to umbrella field, especially a kind of automatic umbrella folding and unfolding structure.

Background technique

What traditional automatic umbrella folding and unfolding structure generallyd use is all that a spring is arranged inside strut, logical after umbrella folds Potential energy is saved after crossing spring-compressed, once triggering umbrella frame opens button, the release of spring potential energy forces umbrella frame to open；But it is such to adopt The spring strength generally chosen with the automatic umbrella-opening structure of a spring is larger, needs when compression strut downwards biggish Strength, and since length is too long, it is flicking and the slack situation of movement can be generated in compression process.

Utility model content

The technical problem to be solved by the utility model is to provide a kind of automatic umbrella folding and unfolding structure, by will be inside support rod Pressure spring is designed to separated multi-segment structure, reduces the length of single hop pressure spring so that the opening of umbrella frame and close it is more smooth, save Power, safety.

In order to solve the above technical problems, the utility model is realized as follows: one kind described in the utility model is certainly Dynamic umbrella folding and unfolding structure includes umbrella frame, upper nest, lower nest, upper rack posts, middle support rod, lower fulcrum bar, great circle pressure spring, ringlet pressure spring, centre Sliding block and handle；The upper rack posts are socketed on middle support rod, and can be moved up and down along middle support rod；The middle support rod socket In on lower fulcrum bar, and can be moved up and down along lower fulcrum bar；Handle is set below the lower fulcrum bar；The upper nest is fixedly connected on branch At the top of bar, lower nest is socketed on upper rack posts, and can be moved up and down along upper rack posts；The umbrella frame is connect with upper nest and lower nest respectively, Lower nest, which moves down, forces rib folding；The intermediate slider is located in strut centre bore, and intermediate slider is socketed on inner catheter, And it can be moved up and down along inner catheter；Multi-diameter shaft is set above the intermediate slider, great circle pressure spring is nested and fixed on multi-diameter shaft, in Between stepped hole is set below sliding block, ringlet pressure spring is set in stepped hole, and ringlet pressure spring is socketed on inner catheter；The lower fulcrum bar Sub warhead is arranged in lower section, and upper nest pulley built in upper nest, lower nest pulley built in lower nest, rope one end is connect with lower nest pulley, another End is connected and fixed after bypassing upper nest pulley with the sub warhead below lower fulcrum bar.

Beam mouth is set below the upper rack posts, and setting flaring, the beam mouth of upper rack posts can be connected to centre above middle support rod It is positioned at the flaring position of strut；Beam mouth is set below the middle support rod, setting flaring, the beam of middle support rod above lower fulcrum bar Mouth can be connected at the flaring position of lower fulcrum bar and position.

The great circle pressure spring pitch is greater than ringlet pressure spring pitch, and great circle pressure spring wire diameter is greater than ringlet pressure spring spring wire Diameter, great circle pressure spring central diameter are greater than ringlet pressure spring central diameter.

Umbrella frame is set on the handle and opens button.

The good effect of the utility model: a kind of automatic umbrella folding and unfolding structure described in the utility model is by will be inside support rod Pressure spring is designed to separated multi-segment structure, reduces the length of single hop pressure spring, solves since pressure spring length is too long, compressed The excessive difficulty of elastic force closes one's umbrella smooth situation in journey, while two pressure springs of segmentation are designed to that different pitches, different spring wires are straight The parameter of diameter and different central diameters reduces pressure spring intensity while not influencing splaying effect, saves required when closing Dynamics.
