Abstract

The utility model relates to an automatically opening /closing structure for four-folding umbrellas, which mainly makes use of a unique roller group to match with a drag rope wound to provide free opening or closing of the four-fold umbrella. The utility model is characterized in that two rollers 11 and 12 are arranged at one side of a movable nest 1; a cylinder 21 is arranged at the same side of an upper nest so that a drag rope 5 is outward extended from a central rod 3; the drag rope is folded five times; the outer end is fixed to an upper nest 2 to get a novel and practical structure of the four-folding umbrella which is automatically opened or closed.

Description

A kind of four folding umbrella automatic umbrella folding and unfolding structures

The utility model relates to the parachute kit class, particularly a kind of four folding umbrella automatic umbrella folding and unfolding structures.

The general parachute kit that can open receipts automatically, mainly be that the spring that is provided with in the rod in utilizing provides elastic force, cooperate the interlock and the blocking of a drag-line and sub warhead, finish opening of parachute kit and receive action, though present various design can reach the effect of opening receipts automatically, but textural comparatively complicated, and the drag-line major part be arranged in excellent around, be easy to generate fault, in addition, because of curtailment, also might cause out receiving the not enough of power, take place and form the situation of not exclusively opening receipts.

But the purpose of this utility model is exactly the shortcoming that exists at above-mentioned general automatic umbrella folding and unfolding tool, and a kind of four folding umbrella automatic deployment structures are provided, and utilizes the ingenious cooperation of drag-line and roller, the length of lengthening drag-line, and major part is the outer fix of rod in being located at, and can make simple structure, opens the debit just.

The technical solution of the utility model:

According to the purpose of this utility model, a kind of four folding umbrella automatic umbrella folding and unfolding structures are provided, mainly be by the roller set of uniqueness cooperate drag-line around, side at movable nest is provided with the second wheel group, homonymy at last nest is provided with cylinder, and drag-line is therefrom stretched out in the rod, via five times the folding around, and nest is fixed in the outer end, obtains the automatic umbrella folding and unfolding structure of a Nover practical.

Accompanying drawings structure of the present utility model and embodiment:

Fig. 1 is the schematic diagram that closes one's umbrella of the present utility model.

Fig. 2 is a parachute-opening schematic diagram of the present utility model.

Fig. 3 is a parachute-opening schematic side view of the present utility model.

1 is that movable nest, 2 is that last nest, 3 is that middle rod, 4 is that umbrella frame frame, 5 is that drag-line, 6 is that sub warhead, 11 is that trundle, 12 is that big roller, 21 is a cylinder.

As accompanying drawing 1 to shown in the accompanying drawing 3, the utility model is by movable nest 1, goes up nest 2, middle excellent 3, umbrella frame frame 4, drag-line 5, sub warhead 6 and constituted, wherein movable nest 1 is sheathed on outside the middle rod 3, can move up and down, excellent 3 upper ends during last nest 2 is fixedly arranged on, and the inner of umbrella frame frame 4 is connected with respectively in last nest 2 and movable nest 1 place, and the inner zygote bullet 6 of drag-line 5 extends in the philtrum rod 3; Side at movable nest 1 is provided with trundle arranged side by side up and down 11 and big roller 12, then be provided with a cylinder 21 at last nest 2 homonymies, make drag-line 5 therefrom the rod 3 protruding after, downwards behind the pile warp trundle 11, upwards walk around cylinder 21, then walk around big roller 12 downwards, more upwards in conjunction with being fixed in nest 2 places, form five sections coilings back and forth, increase its extendible total length; Because the length of drag-line increases, provide five to roll over coiling, be used in the automatic umbrella folding and unfolding of rod in four folding umbrella frames, four joints, and can improve its applicability, in addition, Yin Lasuo 5 all winds the line in middle excellent 3 the same outside, fault rate capable of reducing using.
