Summary of the invention
Technical problem to be solved by this invention provides a kind of sunshading board turning axle mechanism, can double moment of torsion (conventional jump ring) be provided for sunshading board, and can realize again surpassing 180
0Flip angle.
In order to solve the problems of the technologies described above, the present invention provides following technological scheme:
A kind of sunshading board turning axle mechanism of arbitrary overturn angle; Comprise turning axle and single U-shaped jump ring; Wherein said sunshading board comprises skeleton, and turning axle one end inserts in the skeleton, and the part that turning axle inserts skeleton is provided with a gripping section; Its chucking face of said U-shaped jump ring is clamped on the gripping section of turning axle, and opening end is fixed on the skeleton;
Said chucking face comprises the first chucking face and the second chucking face, and each chucking face is provided with axial protuberance; Gripping section is provided with corresponding first axial zone and second axial zone, is equipped with axial tool cutting edge plane and roller bearing face on first axial zone and second axial zone;
Have at least the axial tool cutting edge plane on a roller bearing face and another axial zone to be on the same circumferential position of turning axle on above-mentioned each axial zone; And under original state promptly not under the rollover states, and the clamping equal of chucking face with each the axial tool cutting edge plane on the corresponding axial zone against, the roller bearing face on above-mentioned each axial zone all is located in the axial protuberance of corresponding chucking face;
Also be provided with the 3rd axial zone between first axial zone and second axial zone, the 3rd axial zone is provided with described axial tool cutting edge plane and roller bearing face, and the distribution of axial tool cutting edge plane and the roller bearing face of the 3rd axial zone is identical with first axial zone on the axial position.
Adopt the present invention that following technique effect is arranged:
1, " and the clamping equal of chucking face with each the axial tool cutting edge plane on the corresponding axial zone against; the roller bearing face on above-mentioned each axial zone all is located in the axial protuberance of corresponding chucking face " what say is original state here; Locations of structures under the rollover states does not promptly take place; Have only when the roller bearing face on the axial zone all is located in the axial protuberance of corresponding chucking face, the roller bearing face just can not lean with corresponding original smooth chucking face yet; If the roller bearing face leans with corresponding original smooth chucking face; That chucking face can be elevated; And the chucking face roller bearing face that can't be clamped, only if the extra technical characteristics of setting up, otherwise each chucking face is equal with the axial tool cutting edge plane on the corresponding axial zone and clamping against being unpractical;
Based on this thinking, first and second axial zone by each self-corresponding chucking face equal and against, form two torsional interaction faces, realized double moment of torsion (comparatively conventional jump ring);
2, on the other hand, " having at least the axial tool cutting edge plane on a roller bearing face and another axial zone to be on the same circumferential position of turning axle on above-mentioned each axial zone " is owing in the practical operation, be the circumferential direction rotation of jump ring around turning axle.For ease of analyzing, from the angle of relative movement, also be appreciated that into, turning axle spins in jump ring by the circumferential direction of oneself.
If there is the axial tool cutting edge plane on a roller bearing face and second axial zone to be on the same circumferential position of turning axle on first axial zone; And under original state and the clamping equal of each chucking face with the axial tool cutting edge plane on the corresponding axial zone against; This roller bearing face on first axial zone is bound on the second chucking face, roll turning axle from being spun on so; (be in the axial tool cutting edge plane of same axial zone and the axial protuberance that can not get into the second chucking face is interior; Promptly be the axial tool cutting edge plane that basic and roller bearing face are in same axial straight line, also can not tightened the face clamping) by second.
Second axial zone can in like manner can push away.Therefore first axial zone can not receive the restriction of the second chucking face and stop upset, and second axial zone can not receive the restriction of the second chucking face and stop upset, so just can stop upset when only getting back to corresponding chucking face.
Yet the technical problem that 3 the present invention are solved is the rotation of rounding of overturning at any angle rather than confirming; (then the 3rd axial zone is not limited by the second chucking face yet with the 3rd consistent axial zone of first axial zone distribution so be provided with again; And the 3rd axial zone is not by the clamping of any chucking face under the original state); As long as rationally be provided with between the 3rd axial zone and first axial zone about the gyration of turning axle, just can realize the upset (being equivalent to the 3rd axial zone replaces first axial zone to get back to initial position in advance) of any predetermined angle.
The 3rd axial zone only refers to distribute identical with " identical " of first axial zone; As upwards first axial zone is by be axial tool cutting edge plane, roller bearing face, axial tool cutting edge plane from left to right successively at same view axis, the 3rd axial zone is by being axial tool cutting edge plane, roller bearing face, axial tool cutting edge plane from left to right successively.And identical is not that finger is identical; As the spacing of roller bearing face, axial tool cutting edge plane can be different in the axial direction; Can be such as the axial length of the axial tool cutting edge plane of the 3rd axial zone than the length of second axial zone or weak point (yes satisfy prerequisite on the same circumferential position that the axial tool cutting edge plane that has at least on the 3rd axial zone on a roller bearing face and second axial zone is in turning axle limits under); Also can (prerequisite be that the 3rd axial zone is when forwarding the first chucking face to than the length of second axial zone or weak point; And the clamping equal of the first chucking face with each the axial tool cutting edge plane on the 3rd axial zone against, the roller bearing face on the 3rd axial zone all is located in the axial protuberance of the first chucking face).Except that axial length, the axial tool cutting edge plane width of the axial tool cutting edge plane of the 3rd axial zone and first axial zone is not done concrete qualification aspect width, only otherwise the realization that influences technology fruit of the present invention gets final product.
