Transformation ratio regulating structure of fully-automatic opening/closing umbrella

Abstract

A variable ratio adjustment structure for fully automatic opening and closing umbrellas, including a middle stick group, an umbrella opening and closing ratio mechanism, and an upper nest and a lower nest matched to the middle stick group; the middle stick group is an outer tube, a middle tube, and an inner tube The opening and closing umbrella variable ratio mechanism includes a lower nest stay rope, a middle pipe stay rope and an inner pipe stay rope; wherein one end of the lower nest stay rope is fixed on the middle pipe plug above the middle pipe, and the other end is fixed on the lower nest. One end of the stay rope of the middle tube is fixed at the upper end of the inner tube, and the other end is fixed at the top of the outer tube; one end of the stay cord of the inner tube is fixed at the upper end of the inner tube, and the other end is fixed at the lower end of the outer tube. The structure of the present invention drives the middle rod group through the connection relationship between the lower nest stay rope, the middle pipe stay rope, the inner pipe stay rope and the pipe fittings of the middle rod group, the upper nest and the lower nest, and cooperates with the umbrella opening and closing driving mechanism in the umbrella handle. While the middle tube in the middle moves up and down relative to the inner tube, it realizes the functions of linkage opening and linkage closing of each pipe fitting of the middle stick group and the umbrella surface.

Description

technical field [0001] The invention relates to an umbrella, in particular to a variable ratio adjustment structure of a fully automatic opening and closing umbrella that can realize full opening and full closing control. Background technique [0002] In recent years, due to the erratic climate, everyone has the habit of carrying an umbrella to prevent the sudden heavy rain from being drenched. But the early stage umbrellas need to push the umbrella frame up to a certain position by hand to open the umbrella. In case of a sudden rain, it is often too late to open the umbrella and get wet. Therefore, someone has just designed a kind of umbrella, is provided with a button at the handle, presses this button and can automatically open umbrella and does not have automatic umbrella closing function, still needs both hands to fold umbrella and just can enter when wanting to take a car. In the car, it is still vulnerable to rain in this short period of time, so it loses the conveni...

Problems solved by technology

[0005] It can be seen that the current automatic opening and closing of umbrellas is essentially only the function of automatic opening and semi-automatic umbrella closing, and cannot fully close the umbrella to the open position. The initial state of the umbrella realizes the fully automatic function, and the umbrella must be folded to the fully folded state with the help of a second force
