Embodiment
At first consult Fig. 1, rotating mechanism of the present invention mainly comprises one first member 10, one second member 20, one the 3rd member 30 and one the 4th member 40.As shown in the figure, second member 20 can rotate around one first axial (X-axis) with respect to first member 10, first member 10 can rotate around one second axial (Y-axis) with respect to the 3rd member 30 in addition, and 30 of the 3rd members can rotate around one the 3rd axial (Z axle) with respect to the 4th member 40.The 4th member 40 can be fixed on a base or the supporting plane during assembling, and a flat-panel screens is fixed on second member 20, flat-panel screens just can be rotated around the X in the three-dimensional space, Y, Z axle by rotating mechanism like this.
In the present embodiment, between first, second member 10,20, be provided with the first pad P1 and the second pad P2 of ring-type.As shown in Figure 1, the first pad P1 has a grab P11, and wherein grab P11 is fastened in the draw-in groove 101 of first member 10, so that the first pad P1 is fixed on first member 10; In addition, the second pad P2 is being provided with a plurality of projection P21 on a side of second member 20, and wherein each projection P21 is fastened in the perforate 201 corresponding on second member 20, so that the second pad P2 is fixed on second member 20.
In Fig. 1, a connection piece 50 passes first member 10, the first pad P1, the second pad P2 and second member 20 successively along X-direction, and wherein when first, second member 10,20 rotated relatively, the first pad P1 slided on the second pad P2.In particular, when first, second member 10,20 rotated to a special angle relatively, the first pad P1 and the second pad P2 were bonded with each other, and then reach the function of location.
Consult Fig. 2,3A and 3B again, wherein the enlarged drawing at A place in Fig. 2 presentation graphs 1.As shown in the figure, the first pad P1 is provided with a plurality of protuberance P12 towards the side P10 of the second pad P2, then be provided with corresponding shrinkage pool P22 on this external second pad P2, when first, second member 10,20 rotates to a special angle, protuberance P12 is bonded in the shrinkage pool P22 accordingly, relatively rotates to limit first, second member 10,20.
Then consult Fig. 2,4A～4C in the lump, the second pad P2 is formed with a plurality of slipping plane P201 and depressed part P202 (shown in Fig. 4 A～4C) on the side P20 of the first pad P1.Wherein, shrinkage pool P22 is arranged on the slipping plane P201, has a groove P21 ' respectively on this external each depressed part P202 bottom surface, and the position of groove P21 ' is corresponding to projection P21, and projection P21 is formed on the opposition side of groove P21 '.In the present embodiment, slipping plane P201, depressed part P202, projection P21 and the shrinkage pool P22 on the second pad P2 is symmetrical in X-axis.
Along with first, second member 10,20 relatively rotates, the protuberance P12 on the first pad P1 is sliding on the slipping plane P201 on the second pad P2 He on the depressed part P202 surface.Because the distance between the depressed part P202 and the first pad P1 greater than the distance between the slipping plane P201 and the first pad P1, therefore can have less friction force when the protuberance P12 on the first pad P1 slides into depressed part P202; Otherwise, in the time of when second member 20 rotates to special angle with respect to first member 10 near, protuberance P12 on the first pad P1 and the mutual butt of slipping plane P201, thereby can produce bigger friction force.
Shown in Fig. 4 C, in the second pad P2, be to be connected between slipping plane P201 and the depressed part P202 by mild inclined-plane P203, so not only can slow down first, second member 10,20 resistance when rotated, also can maintain the paragraph sense when rotating simultaneously.
Then consult Fig. 5,6 in the lump, the synoptic diagram that first member 10 and the 3rd member 30 articulate in this two figure presentation graphs 1 has omitted the latch members group J among Fig. 1 among this external Fig. 5,6.As shown in the figure, first member 10 can rotate around second axial (Y-axis) with respect to the 3rd member 30, wherein first member 10 is provided with 30 positions that are provided with at least one second through hole, 301, the second through holes 301 of at least one first through hole, 102, the three members corresponding to first through hole 102.In particular, a connection piece 60 passes first, second through hole 102,301 successively by first member, 10 outsides, and is bonded in first through hole 102, to articulate the first, the 3rd member 10,30.
Consult Fig. 7 again, the figure shows the enlarged drawing of B part among Fig. 6.As shown in the figure, second through hole, the 301 rough figure-8 structures that are, and its aperture area is greater than first through hole 102.In particular, second through hole 301 has two the first side walls that are parallel to each other 3011,3011 ' and two second sidewall 3012,3012 ' that is parallel to each other, has an angle theta between the first side wall 3011,3011 ' and second sidewall 3012,3012 ', wherein 0 °＜θ＜180 °
In addition, web member 60 has two bearing surfaces that are parallel to each other 601,601 ', when first member 10 rotates to one first angle in the counterclockwise direction with respect to the 3rd member 30 (as shown in Figure 7), bearing surface 601 on the web member 60, the first side wall 3011,3011 ' on 601 ' difference butt, second through hole 301 are so that first member 10 is limited in first angle.On the contrary, when first member 10 is rotated in a clockwise direction to one second angle with respect to the 3rd member 30 (as shown in Figure 8), bearing surface 601 on the web member 60,601 ' is second sidewall 3012,3012 ' on butt second through hole 301 respectively then, with so that first member 10 is limited in second angle.
In Fig. 7,8, the upper and lower both sides of second through hole 301 have cambered surface 3013,3013 ' respectively, above-mentioned cambered surface 3013,3013 ' is connected with the first side wall 3011,3011 ' and second sidewall 3012,3012 ', when first member 10 rotated with respect to the 3rd member 30, web member 60 slided along cambered surface 3013,3013 '.Present embodiment limits first member 10 and rotates between first, second angle by second through hole 301 of 8 fonts is set, and so not only can have the function of location, causes the damage of rotating mechanism simultaneously in the time of can avoiding operating because excessively rotate.
Rotating mechanism of the present invention is for example applicable to a flat-panel screens bracing frame, because the advantage that above-mentioned rotating mechanism has easy assembling and can locate rapidly, security and convenience in the time of therefore can promoting operation significantly.
