A kind of parasols bend towards structure
Technical field
The utility model relates to a kind of structure that bends towards of parasols.
Background technology
Traditional parasols bending positioner is made up of institutes such as convex-shaped joint, following spill joint, backstay, spring catch and springs.Wherein, scabble respectively convex-shaped joint cylindric both sides at one end, become the interlocking portion of flat, and the arc round convex shape is formed on the bottom, the top is an arc end, and offer a through hole in central authorities, interlocking portion bottom is arranged with the positioning embeded groove that equidistantly matches, one end connects the umbrella rod for the pipe body, following spill joint is cylindric, offers a short slot that is suitable for convex-shaped joint interlocking portion on the top, makes it to form monosymmetric interlocking rib, the interlocking rib is also offered through hole relatively, the one side interlocking rib below of scarfing slot bottom is arranged with a long arc end groove, is to offer in this groove the square groove that runs through, and establishes a slotted eye in this runs through the groove lower grooves, right joint bottom also becomes the pipe body to connect the umbrella rod, backstay is positioned at the long arc plectane central authorities of spill joint groove down in addition, is convexly equipped with a square bar of vacillating, and in the terminal square inlay card bar that is higher than the square bar of vacillating that forms of this bar of vacillating, multiple in the backstay of the bar below of vacillating, be arranged with a projection again.When the short slot of spill joint was interior under the interlocking portion of described convex-shaped joint embedded, backstay is inserted spring in the slotted eye with the projection location, and the bar and inserting in the groove of vacillating, after so top connection embeds lower contact, spring catch articulates both according to the through hole of interlocking portion and the through hole of interlocking rib, and the mutual inlay card of convex-shaped joint and the inlay card groove bottom interlocking portion and inlay card bar location, and the time push backstay in bending and make the inlay card bar break away from the inlay card groove, the convex-shaped joint can be reached and go up the umbrella rod is the axle center bending with the spring catch, and nationality inlay card bar is different with the inlay card position of inlay card groove, and the bending that reaches different angles is adjusted, the defective of this bending device maximum is the parasols loading of bending angle because of supported by the umbrella rod of convex-shaped joint, and can't be bent to suitable angle inlay card really, especially because of the load effect of parasols, often inlay card bar and inlay card groove one break away from, and promptly bend the excessive fixing puzzlement of inlay card that causes.
For address this problem occurred the patent No. be 00249751.4 parasols bend towards mechanism automatically, comprise bending towards and save and bend towards down joint, bending towards joint one end is the interlocking portion that cylindric its both sides have flat respectively, offers a through hole in the interlocking portion, and the other end is the pipe body; Bend towards down joint and also be the cylindric short slot that is suitable for bending towards joint interlocking portion of offering on the top, and form monosymmetric interlocking rib, two rabbet the through hole that has fixing pin to use on the rib relatively, the interlocking portion that bends towards joint is embedded in the short slot that bends towards down joint and with pin and articulates both, it is characterized in that: the interlocking portion of joint has a groove on bending towards, one inner spring places in this groove, save and bend towards down the pin that saves and pass inner spring and articulate to bend towards, one bends towards connecting rod places bending towards of mutual pivot joint to save and bend towards down in the joint, and its bottom is positioned at the bottom that bends towards down joint, the afterbody of connecting rod has two pulleys that connect with sliding pin, the chute that under the bending towards of short slot bottom, has this pulley to slide in the joint, a limit plug is fixed on the connecting rod top, the limit plug top be connected one with umbrella handle on the fixing back-moving spring of joint, a pulley is housed in the joint on above this spring, an end of umbrella rope is fixed with following nest, the other end is through pulley and run through back-moving spring successively, bends towards to save with bending towards down to save to be connected with crank.Its advantage is to have good looking appearance, and is simple to operate, durable, the advantage that can in 0~28 ° of gradient scope, locate arbitrarily etc., and its defective is the steering structure complexity, manufacturing cost height, and do not have effort-saving mechanism, it is light to rotate underaction, needs further to improve.
