the specific embodiment
A kind of multipurpose collapsible, expandable stent comprise support bar and 2 above collapsible unit that open.Wherein support bar is Collapsible structure, comprise upper support bar 5 and lower support bar 17, upper support bar 5 tops are provided with fixed cover 1, upper support bar 5 is provided with can be along the middle slip cap 7 of its longitudinal sliding motion, is also provided with at the locating ring 6 between fixed cover 1 and middle slip cap 7 and the supporting spring 8 being arranged in below slip cap 7 on upper support bar 5; Lower support bar 17 can slide up and down in upper support bar 5, and lower support bar 17 is provided with can be along the lower slider cover 12 of its longitudinal sliding motion.
The collapsible unit that opens comprises: the folding unit that the push-and-pull unit that upper support unit, the 3rd pull bar 11 and the 4th pull bar 10 that lower support unit, the second pull bar 2 and the second folding rod 3 that the first pull bar 9 and the first folding rod 18 form forms forms and the 3rd folding rod 14 and the 4th folding rod 16 form.The first pull bar 9 two ends are hinged on respectively on lower slider cover 12 and the first folding rod 18, first folding rod 18 one end are hinged on middle slip cap 7, first folding rod 18 other ends be articulated and connected the 3rd pull bar 11 one end and the 4th pull bar 10 one end simultaneously, and second folding rod 3 one end are articulated and connected on the first folding rod 18, hinged the 3rd folding rod 14 one end of second folding rod 3 other ends, the 4th folding rod 16 one end that are articulated and connected on the 3rd folding rod 14, the 4th folding rod 16 other ends are free end; The second pull bar 2 two ends are hinged on respectively on lower slider cover 12 and the second folding rod 3, the 3rd pull bar 11 other ends are hinged on the 3rd folding rod 14, the 4th pull bar 10 other ends are rotationally connected swingle 4 one end, swingle 4 other ends are rotationally connected the 5th pull bar 15 one end, and swingle 4 is hinged on the 3rd folding rod 14 and can rotates with pin joint, the 5th pull bar 15 other ends are rotatably connected on the 4th folding rod 16.
Collapsible open unit and launch after the first folding rod 18 and the second folding rod 3 laterally parallel, the 3rd folding rod 14 and the 4th folding rod 16 vertically parallel, and are inverted L-shaped.Form the first pull bar 9, the first folding rod 18 and lower support bar 17 simultaneously and intersected formation triangle; The second pull bar 2, the first folding rod 18 and the second folding rod 3 and upper support bar 5 intersect formation triangle; The first folding rod 18 and the second folding rod 3, the 3rd folding rod 14 and the 3rd pull bar 11 intersect formation triangle.
Between the first pull bar 9 and low sleeve, between the first folding rod 18 and middle sliding sleeve, between the second pull bar 2 and upper sliding sleeve, be all connected by rotating shaft 21 between the 3rd pull bar 11 and the 4th pull bar 10 and the first folding rod 18.Between the first folding rod 18 and the first pull bar 2, between the second folding rod 3 and the first folding rod 18, between the second pull bar 2 and the second folding rod 3, be all connected by U-shaped hinged component 19 and axis body 20 between the 4th folding rod 16 and the 3rd folding rod 14, and all can rotate around axis body 20.
When operation: one holds handle 13, one pushes slip cap 12 on hand, by lower slider overlap 12 and middle slip cap 7 between the first pull bar 9 of being connected and the first folding rod 18 promote in slip cap 7 upward slidings, because fixed cover 1 is fixed on center-pole, on middle slip cap 7, move and force the second pull bar 2 to press down the outwards expansion downwards of the second folding rod 3, drive the 3rd folding rod 14 being connected with it descending by the second folding rod 3, the 4th folding rod 16 that the 3rd 14 of folding rods drive is connected with it is descending simultaneously; On push slip cap 12, the first pull bar 9 that simultaneously promotes to be connected with it promotes the lower end of the first folding rod 18 being connected with the first pull bar 9 and upwards outwards launches, the 3rd pull bar 11 that band is automatically connected in the folded bar of first fold 18 lower ends promotes the 3rd folding rod 14 and outwards launches, swingle 4 lower ends that the 4th pull bar 10 that simultaneously promotes to be connected with hole with the 3rd pull bar 11 with its lower end promotes to be arranged on the 3rd folding rod 14 inwardly rotate, thereby drive the 5th pull bar 15 being connected with swingle 4 other ends to promote the outside drops down of the 4th folding rod 16 being connected with it.In the middle of slip cap 7 arrive on center-pole locating ring 6 time stop, lower slider cover 12 stops after rising to and being held by the supporting spring 8 on center-pole, now the first folding rod 18 and the second folding rod 3 laterally parallel, the 3rd folding rod 14 and the 4th folding rod 16 vertically parallel, and have so just formed the first pull bar 9 and the first folding rod 18 and the crossing triangle of center-pole; The second pull bar 2 and folding rod the first folding rod 18, the second folding rod 3 and the crossing triangle of center-pole; The first folding rod 18, the second folding rod 3 and the 3rd folding rod 14 and the crossing triangle of the 3rd pull bar 11, the stretching, extension of whole units folded structure completes, due to the distinctive stability of triangle, so folding unit is relatively firmly not yielding after launching.
This foldable structure is by the length of increase and decrease the 3rd pull bar 11, and the position of adjusting the 3rd folding rod 14 and the 3rd pull bar 11 tie point holes 22 can change be arbitrarily connected with the 3rd folding rod 14 angle of angle of the second folding rod 3.This foldable structure can also add arbitrarily multiple folding units, installs corresponding push-and-pull unit additional simultaneously.According to design needs, slip cap can connect N the collapsible unit that opens, again by adjusting the angle of the second folding rod 3 and the 3rd folding rod 14 angles (Yi Ban Yong≤90o), on push away or do not push away center-pole, product design can be become to the products such as polygon or circular Folding umbrella, parasol, break camp.Than existing folded umbrella, tent more convenient operation, to strut rear structure more firm.
