Problems solved by technology

Umbrellas need to be operated with both hands when opening and closing, which is very inconvenient to use
Therefore, people have developed an umbrella that can be opened and closed automatically. The existing automatic open and close umbrella mainly drives the umbrella rod to automatically expand and contract through the screw structure or the flexible rack. The pole is stuck, making the umbrella pole lift very unstable
The umbrella opened and closed through the flexible rack, because the flexible rack is relatively soft, the flexible rack is easy to bend when the umbrella rod is extended, so that the flexible rack loses its supporting force instantly, which easily leads to damage to the rack, and the umbrella cannot automatically Open

Abstract

The invention discloses an automatic opening and closing structure for a retractable umbrella. The automatic opening and closing structure comprises an umbrella rod and an opening and closing device; the opening and closing device comprises a flexible steel bar, a telescopic connecting piece and a steel bar driving device; the steel bar driving device is arranged at the lower end of the umbrella rod; one end of the flexible steel bar is connected with the upper end of the umbrella rod, and the other end of the flexible steel bar is connected with the steel bar driving device; the upper end of the telescopic connecting piece is connected with the upper end of the umbrella rod; the lower end of the telescopic connecting piece is connected with the lower end of the umbrella rod; a fixing hole allowing the flexible steel bar to penetrate is formed in the telescopic connecting piece;the telescopic connecting piece comprises a first connecting single body and a second connecting single body which are arranged at intervals. Compared with the prior art, the opening and closing structure is firm and compact, and can stably stretch out and draw back the umbrella rod. The invention also discloses an automatic retractable umbrella. The automatic retractable umbrella further comprises umbrella ribs and an umbrella cover; the umbrella ribs are connected with upper nests and lower nests; and the umbrella cover is connected to the umbrella ribs. Compared with the prior art, the automatic retractable umbrella can be automatically and stably opened and closed, is high in the structural strength, and convenient in opening and closing operation.

Description

technical field [0001] The invention relates to the field of umbrellas, in particular to a telescopic umbrella automatic opening and closing structure and an automatic telescopic umbrella. Background technique [0002] An umbrella is a tool for shading or sheltering from rain and snow. Umbrellas need both hands to operate when opening and closing, which is very inconvenient to use. Therefore, people have developed an umbrella that can be opened and closed automatically. The existing automatic open and close umbrella mainly drives the umbrella rod to automatically expand and contract through the screw structure or the flexible rack. The pole is stuck, making the umbrella pole lifting very unstable. The umbrella opened and closed through the flexible rack, because the flexible rack is relatively soft, the flexible rack is easy to bend when the umbrella rod is extended, so that the flexible rack loses its supporting force instantly, which will easily lead to damage to the rac...
