[0003] However, when the umbrella is retracted in the above situation, it can only automatically perform the action of retracting the umbrella surface, and to achieve the purpose of completely retracting the umbrella, the middle stick must be pressed into the handle (umbrella head) by hand, otherwise it cannot be used next time. At this time, because the middle stick of the umbrella is fully opened, the length of the umbrella is longer, and the stroke that needs to be pressed in is just longer, and a larger force is needed to press the middle stick into the umbrella head. There are certain difficulties in the operation mode, so the automatic opening and closing umbrella also has certain inconvenience

Embodiment Construction
[0046]The main feature of the present invention is to set at least two stay wires: the main wire and the auxiliary wire, and the main wire and the auxiliary wire are fixed together (the fixing method can be directly fixed or indirectly fixed). The balance of the movement is maintained during the process, so as to realize the effect of gathering the rod in the part. The specific implementation of the present invention will be described in detail below from several aspects of the setting of the pull wire and the specific realization.
[0047] figure 1 , figure 2 As shown, it is a structural schematic diagram of the present invention applied to the three-fold automatic opening and closing umbrella. figure 1 Assembly drawing shown, figure 2 for figure 1 As shown in the exploded view, the parts shown in the figure are consistent with the existing three-fold automatic opening and closing parts except for the structure of the backguy and the parachute opening spring. That is to...

The invention discloses a stay guy structure for automatically unfolding and folding an umbrella. The stay guy structure comprises at least two stay guys, one stay guy serves as the main guy and the other serves as an auxiliary guy. One end of the auxiliary guy is connected on a lower nest and the other end goes round an upper nest or a tube section fixed together with the upper nest to be fixed on the main guy. One end of the main guy goes round a central rod tube section which is arranged in a central rod and can move relatively to the upper nest and the other end of the main guy is connected with an extension part arranged in the head of the umbrella. When the stay guy structure is used to unfold the umbrella, an umbrella spring splays, the main guy and the auxiliary guy match with each other to pull the other tube sections of the central rod to splay to unfold the central rod and to enable the lower nest to move upward so as to unfold the ribs of the umbrella, and in this way, the umbrella can be totally unfolded. When the stay guy structure is used to fold the umbrella, the lower nest moves downward under the action of an umbrella folding spring to fold the central rod tube section above the umbrella unfolding spring through the action of the main guy, or the auxiliary guy or both, so part of the tube sections of the central rod can be folded when the canopy of the umbrella is folded and the length of the central rod can be effectively reduced after the umbrella is unfolded.
Description
technical field [0001] The invention relates to automatic opening and closing of umbrellas, and specifically relates to a pull wire structure for automatic opening and closing of umbrellas. The pull wire structure can automatically recover a part of the middle rod when retracting the umbrella, and shorten the length of the umbrella in the retracted state. Background technique [0002] The automatic umbrella, also known as the automatic opening and closing umbrella, is a kind of umbrella that uses the umbrella opening spring and the umbrella retracting spring to automatically open the umbrella and retract the umbrella surface. The automatic umbrella can automatically open and retract the umbrella surface only by pressing the button on the handle, which is convenient The control operation of people is improved, and when the umbrella is closed, it is not necessary to close the umbrella manually, and the rainwater will not splash on people. [0003] However, when the umbrella is...
