Automatic opening and retracting control device with safety structure for multi-folding umbrella

Abstract

The invention relates to an automatic opening and retracting control device with a safety structure for a multi-folding umbrella. The automatic opening and retracting control device comprises an opening and retracting control device and an umbrella retracting safety device, wherein a ratchet claming piece (85) of the umbrella retracting safety device comprises a clamping block (851), a shift block (852) and reset pieces of the clamping block (851) and the shift block (852), one end of the clamping block (851) is opposite to teeth of a ratchet (82), the other end of the clamping block (851) is opposite to the shift block (852), and the shift block (852) is provided with a convex sheet (855). The resetting piece (854) of the shift block acts on the shift block (852), so as to maintain a trend that the convex sheet (855) on the shift block (852) extends into groove holes which are formed in an umbrella middle rod (20) and the side wall of a control pipe (6). When a billiard descends to an umbrella retracting state, the shift block (852) is pushed outwards, so the clamping block (851) is shifted, and the lower end of the clamping block (851) is tilted and disengaged from the ratchet. The automatic opening and retracting control device has the advantage that only one narrow groove is arranged on the side wall of an inner pipe of the middle rod, so the sufficient strength of the side wall of the inner pipe of the middle rod is ensured, and the force for umbrella retracting and middle rod folding is greatly reduced; and the structure is simple, the fault rate is low, and the easy assembly is realized.

Description

technical field [0001] The invention relates to an umbrella structure for daily use, in particular to the improvement of a multi-fold umbrella automatic opening and closing control device with a safety structure. Background technique [0002] In the existing automatic opening and closing multi-folding umbrella, the opening and closing control device is to realize the purpose of opening the umbrella by pressing the control button on the umbrella handle to release the outer tube of the lower nest or the middle rod or to fold the umbrella rib and the umbrella surface. The purpose of retracting the umbrella is very convenient to use, but there is a safety hazard in this automatic opening and closing of the umbrella: there is an umbrella opening spring for springing and stretching the folded middle rod tube inside the umbrella rod, and its elastic force is very large. After the umbrella surface is folded, the umbrella rod must be compressed to the locked position when the umbrell...

Problems solved by technology

[0004] However, the above-mentioned umbrella retracting safety structure needs to open a hole at the position corresponding to the umbrella opening and retracting device on the middle rod inner tube so that the positioning part of the buckle can be stretched in, and it also needs to be connected with the positioning block on the other side of the middle rod inner tube. 105 A larger hole is opened at the position opposite to the bump 107, so that the buckle head can act on the bump 107, and the strength of the middle rod will be greatly reduced. During use, the middle rod is subjected to a certain external force such as torsion However, the position of the hole is easily damaged and the umbrella cannot be used, and this structure is inconvenient to assemble
