The utility model has the following advantages that：
1st, the structure being all hinged using pole, connecting rod, service life is long, and fault rate is low.
2nd, pin joint is optional, to adapt to different height people or bend over to overlook the people of back different angle use, the scope of application
Extensively.
3rd, the collar and waistband plug can be connected as one and the collar is directly sleeved on lower fulcrum bar and used, inherited existing
There is improved structure in technology.
Brief description of the drawings
Accompanying drawing 1 is the utility model structural representation.
1 is lower fulcrum bar in figure, and 3 be second connecting rod, and 5 be corner amplification pole, and 7 be first connecting rod, and 9 be fastening sector
Wheel, 11 be upper rack posts.
Embodiment
The automatic both shoulders for keeping umbrella to balance vertically back of the body umbrella stand, including upper rack posts (11), lower fulcrum bar (1), with Braces hanged over tow shoulders
Backrest (13), upper rack posts (11) are with the first backrest fulcrum shaft O1It is hinged；Band extension spring between upper rack posts resistance arm and backrest (13)；Under
Pole (1) is with the second backrest fulcrum shaft O2It is hinged.Therefore, upper rack posts can only be around the first backrest fulcrum shaft O by limitation1Rotate, draw
The pulling force of spring makes upper rack posts Connectable umbrella pommel (namely upper rack posts resistance arm end) be drawn close to backrest.Lower fulcrum bar also can only be around
Two backrest fulcrum shaft O2Rotate.Improvements of the present utility model are also to include corner amplification pole (5).The corner amplification branch
Bar is hinged with the 3rd backrest fulcrum shaft O3.Therefore, corner amplification pole also can only be around the 3rd backrest fulcrum shaft O3Rotate.
First connecting rod (7) two ends are hinged with upper rack posts (11), corner amplification pole (5) respectively.Therefore first connecting rod two ends
It can be rotated respectively around pin joint D and pin joint C.
Second connecting rod (3) two ends are hinged with lower fulcrum bar (1), corner amplification pole (5) respectively.Therefore, second connecting rod two ends
It can be rotated respectively around pin joint A and pin joint B.
First connecting rod amplifies the backrest fulcrum shaft O of pin joint C distances the 3rd of pole with corner3Put than second connecting rod with corner
The backrest fulcrum shaft O of pin joint B distances the 3rd of big pole3It is long.That is, straight line CO3Distance is than straight line BO3It is long.Therefore, when
Corner amplification pole (5) is around the 3rd backrest fulcrum shaft O3When rotating and turning over an angle, the thread of C points movement is moved than B point
Thread it is long.So, when lower fulcrum bar (1) is around the second backrest fulcrum shaft O2When turning over an angle [alpha], corner amplification pole will
Around the second backrest fulcrum shaft O3Rotation, the angle of rotation will be β=α × AO2/BO3.And upper rack posts (11) will be around first back of the body
Frame fulcrum shaft O1Angle γ=β × CO3/DO1.β is substituted into and produces γ=α (AO2/BO3)(CO3/DO1).If AO2With DO1Length
It is roughly equal, then γ ≈ α (CO3/BO3).So, pin joint C and pin joint B in corner amplification pole (5) are played and are allowed lower branch
Bar (1) makees α angular turns and zooms into upper rack posts (11) must and then to make the effects of γ angular turns.
In order to control the angle γ that upper rack posts are rotated, corner can be allowed to amplify pole (5) and carried no less than two with second
The optional pin joint that connecting rod (3) end is hinged.In use, one of them pin joint of selection is hinged with second connecting rod as needed.
Likewise, in order to control the angle γ that upper rack posts are rotated, corner can be allowed to amplify pole (5) and carried no less than two
The optional pin joint that same first connecting rod (7) end is hinged.In use, selecting one of them same first connecting rod of pin joint as needed
It is hinged.
Fixed to will be turned over the upper rack posts after an angle using with a certain size active force, the first backrest fulcrum shaft
O1On can fasten sector gear (9) so that compact conformation, sector gear is fixed together with backrest (13).In use, can
To install hammer pendulum and tongue latch additional on upper rack posts.
In use, umbrella handle is fixed together with upper rack posts, unfurl an umbrella, backrest worn on the back.Lower fulcrum bar is inserted into
Among the collar, then it is inserted on waistband integral waistband plug is fixed on the collar.Different height and different motion in reality
The people of custom, it is different that it, which is bent over to the angle that work waist of bending is turned over,.Appropriate pin joint may be selected, to control upper branch
The bar angle to be rotated.When work above the waist is bent down when bending over, lower fulcrum bar under effect, produces rotation in waistband between backrest
And turn over an angle.Now, the corner size to upper rack posts of corner amplification pole has control, forces upper rack posts to rotate rule
Fixed angle, allows upper rack posts to keep vertical.Extension spring is stretched.Bowed from bending over above the waist when returning back to standing state, extension spring is by upper branch
Bar retracts vertical state, while lower fulcrum bar is slided in the collar transfers back to initial angle.
