Abstract

The utility model discloses an improved omnidirectional parasol which can be freely veered. The improved omnidirectional parasol is characterized in that a universal joint veering structure is made to be arranged at the connecting position of an upper extension rod and a lower extension rod of an umbrella handle. In the structure, the bottom end portion of the upper extension rod is made to be a globular circular bead and a positioning central rod. The upper end portion of the lower extension rod is made to be a star-shaped movable trepan boring which is movably sheathed with the globular circular bead and the positioning central rod. In addition, the outer ring of the movable trepan boring is provided with a fixing casing and positioning screws. The new improved omnidirectional parasol has simple structure, assembled simply, convenient operation and flexible rotation. The improved omnidirectional parasol can effectively shield the irradiation of hot sunlight.

Description

Omnidirectional parasol

The utility model is a kind of parachute kit that sun-shading rainproof is used that is used for, particularly a kind of improved parasol that can comprehensively turn to.

The parasol of production and sales on the existing market, its umbrella handle has plenty of by single extension bar to be formed, have plenty of and be fixed socket-connecting with two extension bars up and down and form, the parasol of this spline structure all is vertical type in use and can't freely tilts, the height of parasol is generally about 2.5 meters, wide about 2 meters, mobile adjustment is very inconvenient, in the time of sun oblique illumination, people often will overcome difficulties firmly to move and regulate the sunshade direction of parasol, otherwise the parasol of these vertical types just can't reach effective shaded effects, makes visitor's rest be subjected to certain influence.Also there are these same problems in the parasol that uses on little stand, city, and in view of the foregoing, two extension bars were made the structure that the constant tilt formula is joined about its umbrella handle of the parasol that has was simply used.But the parasol of this structure is regulated and use still sense very inconvenient.

The purpose of this utility model is a kind of improved comprehensive parasol of design, and people can turn to adjusting arbitrarily easily according to the gradient of solar rays.

The utility model is to form in the technical improvement that has parasol now, whole umbrella still by umbrella cover, support the umbrella muscles and bones frame of umbrella cover and up and down the extension bar umbrella handle that forms that joins form, the design feature of this novel sun umbrella is that the junction between last extension bar and following extension bar is designed to have the tuning structure of universal joint, this universal connecing in the tuning structure, specifically be the spherical shoulder of the bottom connecting portion of last extension bar being made annular, also expose the center-pole of a bit of location usefulness in the bottom of spherical shoulder; To descend again the upper end connecting portion of extension bar make can with spherical shoulder and centre of location bar thereof mutually pivot bush unit cooperate "

" the movable trepanning of shape; The place, outer of extension bar junction is furnished with fixed jacket again about the outer ring of this activity trepanning is, also is provided with the dog screw of a fastening usefulness on fixed jacket.

Below in conjunction with embodiment concrete structure of the present utility model and use principle are described further:

Fig. 1 is the universal assembling schematic diagram that connects the tuning structure on this novel sun umbrella umbrella handle;

Fig. 2 is the user mode figure of this novel sun umbrella.

Above-mentioned accompanying drawing is a kind of embodiment of the utility model parasol, wherein: extension bar on 1,2 times extension bars, 3 spherical shoulders, 4 centre of location bars, 5 fixed jackets, 6 dog screws, 7 Sealing shield rings, 8 movable trepannings, 9 umbrella covers.

When making assembling, on the spherical shoulder 3 on the last extension bar 1 and centre of location bar 4 and the following extension bar 2 " " the movable trepanning 8 of shape is matched in clearance (promptly movable the cooperation); the upper edge hole inboard at fixed jacket 5 can be provided with Sealing shield ring 7, during use, goes up extension bar 1 as required and can slightly upwards mention easily; the Sealing shield ring 7 on the fixed jacket 5 can block spherical shoulder 3, and extension bar disconnects mutually about preventing.Fixed jacket 5 has also been strengthened the intensity of whole tuning junction simultaneously.

The use principle process of the utility model parasol is as follows: the same with existing parasol, strut umbrella cover and get final product sunshade, when the sun shines at noon right overhead, directly allow centre of location bar 4 under its spherical shoulder 3 just in time be socketed in down the bottom of the movable trepanning 8 of extension bar 2 last extension bar 1 pendulum, dog screw 6 is screwed, and parasol just is vertical state sunshade.When the sun is the gradient irradiation on high, in order to keep the sun off effectively, earlier fastening dog screw 6 is loosened during tuning, to go up extension bar 1 more upwards mentions, allow centre of location bar 4 pull away the bottom of movable trepanning 8, but umbrella cover is omnibearing tilt just, adjusts required gradient and direction, and screwing dog screw again can use.

Parasol of the present utility model is simple in structure, assembles simple and easyly, easy to operate, rotates flexibly, can keep the sun off to greatest extent at any time, and is very easy to use on tourist spot, beach swimming and stand.
