Embodiment
See also Fig. 1 to Fig. 4, be first kind of embodiment of the present utility model, a kind of two born of the same parents' pivot devices 10 with positioning pipe spring cover are provided, mainly constituted by a pair of born of the same parents bolster 11, positioning pipe spring cover 12 and one turning shaft structure 13.
Double bearing frame 11 of the present utility model has a fixed plate 111, one end of this fixed plate 111 forms two oppositely bending and first and second sleeve part 112a and 112b at interval, form a breach 113 between the free terminal of each sleeve part 112a and 112b and the fixed plate 111, promptly the breach 113 of first and second sleeve part 112a and 112b is respectively the both sides at fixed plate 111.And positioning pipe spring cover 12 is set in the interval of first and second sleeve part 112a and 112b and together rotate.Positioning pipe spring cover 12 is a cylindrical shape, and on its cylinder, have one with the grooving 121 of parallel to an axis, on columnar surface, form in addition pair of planar piece 122a and 122b (shown in Fig. 1 and Figure 1A), this to flat blocks 122a and 122b from extrusion outside to inside.The positioning pipe spring overlaps 12 both sides and has a pair of projection 123a and 123b, and first and second sleeve part 112a of double bearing frame 11 and 112b overlap 12 adjacent sides edge relative formation one recess 114a and 114b respectively with the positioning pipe spring, and this snaps in relative this recess 114a and 114b respectively to projection 123a and 123b.
In addition, turning shaft structure 13 of the present utility model has an axial region 131, first and second sleeve part 112a of these two bendings of confession and 112b and this positioning pipe spring overlap 12 fits so that elastic force to be provided, and make that double bearing frame 12 can axial region 131 be the center rotation, and in arbitrary angular positioning.These axial region 131 1 terminal fixedly connected fixed bases 132.Again, these axial region 131 circular appearances form pair of planar 133a and 133b, can be referring to Figure 1B and shown in Figure 4, this rotates to 0 when spending to plane 133a and 133b at double bearing frame 12, with this of positioning pipe spring cover 12 flat blocks 122a and 122b is fitted so that the auto-closing function to be provided.
Shown the reason that the utility model auto-closing produces at Fig. 5.This of positioning pipe spring cover 12 be during to angle beyond 0 degree of flat blocks 122a and 122b, partly contact with axial region 131 circular and can produce distortion, makes grooving 121 expansions; When double bearing frame 12 rotations are spent near 0, because the restoring force of positioning pipe spring cover 12 distortion, this is fitted to plane 133a and 133b from trend to flat blocks 122a and 122b to make this, and the auto-closing power that double bearing frame 12 produces to arrow G 1 direction, to reach the auto-closing function.
Reaching (B) at Fig. 6 (A) is the torsion variation diagram of first kind of embodiment's pivot device 10; From 0 degree breakdown action, Fig. 6 (B) then represents closed action in Fig. 6 (A) expression.Because first and second sleeve part 112a and the 112b length of the reverse bending of double bearing frame 11 are identical, make pivot device 10 identical approximately with torque value T2 in the body closure or openness process at loam cake, for example be 5Kgf.cm.In Fig. 6 (A), open moment,, can make torsion increase to T1 because this will break away from this to plane 133a and 133b to flat blocks 122a and 122b from 0 degree.Be closed to 0 at Fig. 6 (B) and spend moment,, make and torsion can be reduced near 0 value because the deformation-recovery power of positioning pipe spring cover 12 produces the auto-closing function.
See also shown in Figure 7ly, be second kind of embodiment's of the utility model pivot device 20, itself and first kind of embodiment's pivot device 10 is similar, mainly is made of a pair of born of the same parents bolster 21, positioning pipe spring cover 22 and one turning shaft structure 23.Different, be that the positioning pipe spring overlaps 22 both sides and has a pair of recess 223a and 223b, and first and second sleeve part 212a of double bearing frame 21 and 212b overlap 22 adjacent sides edge relative formation one projection 214a and 214b respectively with the positioning pipe spring, and this is snapped in by relative this projection 214a and 214b respectively recess 223a and 223b.
See also shown in Figure 8ly, be the third embodiment's of the utility model pivot device 30, itself and first kind of embodiment's pivot device 10 is similar, mainly is made of a pair of born of the same parents bolster 31, positioning pipe spring cover 32 and one turning shaft structure 33.Different, this of positioning pipe spring cover 32 is the plane that folds on cylindrical shape across both sides to flat blocks 322a and 322b.
See also shown in Figure 9ly, be the 4th kind of embodiment's of the utility model pivot device 40, itself and the third embodiment's pivot device 30 is similar, mainly is made of a pair of born of the same parents bolster 41, positioning pipe spring cover 42 and one turning shaft structure 43.Different, be that the positioning pipe spring overlaps 42 both sides and has a pair of recess 423a and 423b, and first and second sleeve part 412a of double bearing frame 41 and 412b overlap 42 adjacent sides edge relative formation one projection 414a and 414b respectively with the positioning pipe spring, and this is snapped in 414a and 414b by this relative projection respectively to recess 423a and 423b.
