Abstract
A kind of concealed multi-section umbrella middle-rod stretching structure, at least comprise in first excellent in rod and second, in described second, rod is enclosed within the outer wall of rod in described first, can relative to described first in rod slide, in described first, the top of rod is provided with in first and fills in, in described second, the top of rod is provided with in second and fills in, the first through hole is provided with beyond the Great Wall in described first, the first tubular support member is provided with in rod in described second, the upper end of described first support member is fixedly connected with the described second interior plug, the lower end of described first support member is through in described first through hole, the first stay cord is provided with in rod in described first, the upper end of described first stay cord is connected with the lower end of described first support member after walking around the fulcrum be located in described first beyond the Great Wall, the lower end of described first stay cord is connected with winding mechanism.The utility model is owing to instead of the spring structure in biography in rod with support member and structure of tow line, therefore, the utility model has can be matching used without the need to middle excellent spring with complete automatic umbrella folding and unfolding, the advantage that reliability is high; In addition, the first support member is set to cylindrical shape, when closing one's umbrella, described second support member can directly insert in the first support member, and its stablizing effect is better.
Description
Technical field
The utility model relates to a kind of concealed multi-section umbrella middle-rod stretching structure.
Background technology
Existing automatic umbrella is semi-automatic umbrella mostly, and one is after pressing shift knob, and umbrella can self-supporting be opened, and again presses the button, and umbrella frame shrinks automatically, more artificial by middle rod extruding contraction, reaches the object closed one's umbrella completely.Another kind is when parachute-opening, needs manually to strut, when needs close one's umbrella, presses the button, and umbrella frame and middle rod draw in completely, complete and close one's umbrella.In prior art, no matter be first parachute-opening, then rod in manual compression contraction, or first manually unfurl an umbrella, then, then close one's umbrella.Its parachute-opening or to close one's umbrella be all coil tension spring with being located in middle rod, and the umbrella colsing spring be located on umbrella frame realizes.Rely on completely the spring storage power of frame for movement and release force realize in the contraction of rod or extension, there is the problem of two aspects, on the one hand it can not realize umbrella shaft truly completely automatically, namely to the automatic extension of umbrella shaft with automatically shrink; The stability that on the other hand, rod is flexible is bad, and there is potential safety hazard.Therefore, a kind of umbrella shaft stretching structure that can be suitable for complete automatic umbrella folding and unfolding of necessary research, and do not rely on the effect of spring, thus meet market demand.
Utility model content
In order to overcome the problems referred to above, the utility model to society provide a kind of can concealed multi-section umbrella middle-rod stretching structure without the need to middle excellent spring matching used with complete automatic umbrella folding and unfolding.
The technical solution of the utility model is: provide a kind of concealed multi-section umbrella middle-rod stretching structure, at least comprise in first excellent in rod and second, in described second, rod is enclosed within the outer wall of rod in described first, can relative to described first in rod slide, in described first, the top of rod is provided with in first and fills in, in described second, the top of rod is provided with in second and fills in, the first through hole is provided with beyond the Great Wall in described first, the first tubular support member is provided with in rod in described second, the upper end of described first support member is fixedly connected with the described second interior plug, the lower end of described first support member is through in described first through hole, the first stay cord is provided with in rod in described first, the upper end of described first stay cord is connected with the lower end of described first support member after walking around the fulcrum be located in described first beyond the Great Wall, the lower end of described first stay cord is connected with winding mechanism.
As to improvement of the present utility model, also comprise rod in the 3rd, in described 3rd, rod is enclosed within the outer wall of rod in described second, can relative to described second in rod slide, in the described 3rd, the top of rod is provided with in the 3rd and fills in, the second through hole is provided with beyond the Great Wall in described second, the second support member is provided with in rod in the described 3rd, the upper end of described second support member is fixedly connected with the described 3rd interior plug, the lower end of described second support member extend in described columnar first support member through described second through hole, the second stay cord is provided with in rod in described second, the upper end of described second stay cord is connected with the lower end of described second support member after walking around the fulcrum be located in described second beyond the Great Wall, the lower end of described second stay cord is fixedly connected with the described first interior plug.
As to improvement of the present utility model, described second support member can be sheet, bar-shaped or tubular.
The utility model is owing to instead of the spring structure in biography in rod with support member and structure of tow line, therefore, the utility model has can be matching used without the need to middle excellent spring with complete automatic umbrella folding and unfolding, the advantage that reliability is high; In addition, the first support member is set to cylindrical shape, when closing one's umbrella, described second support member can directly insert in the first support member, and its stablizing effect is better.
