Description of drawings:

Accompanying drawing 1 is a structural representation of the present utility model.

Embodiment:

See shown in the accompanying drawing 1, the utility model includes rotary seat 10, these rotary seat 10 middle part upsides are connected with a connecting seat 20, and the two ends, the left and right sides of rotary seat 10 are combined with pivot joint bearing pin 30, rotary seat 10 is connected for rivet with articulating between the bearing pin 30, and form the edge of folding down in the connecting part of rotary seat 10, articulate the linkage section of bearing pin 30 with this double team.The overhanging end that articulates bearing pin 30 is arranged in a fixed base 40, wherein articulate on bearing pin 30 overhanging ends and have the face of scabbling 31 at least, it is connected with an eccentric structure 50 after being arranged in fixed base 40, this eccentric structure 50 includes a positioning wheel 51 and a roulette wheel 52, roulette wheel 52 is synchronous with pivot joint bearing pin 30, hole shape, size and pivot joint bearing pin 30 are complementary in the socket of roulette wheel 52, utilize and scabble relation of plane, and deduction and exemption relatively rotate.Junction plane between positioning wheel 51 and roulette wheel 52 has ripple arc embedded structure, promptly is provided with trough concave arc 521 or at 511 o'clock and then is provided with crest convex arc 512 or 522 at the corresponding position of positioning wheel 51 or roulette wheel 52 on the junction plane of roulette wheel 52 or positioning wheel 51.Described trough concave arc 521 or 511 roulette wheel 52 or positioning wheel 51 in conjunction with end face in be at interval design in four fens, promptly the angle between the trough concave arc is 90 ° in twos, can certainly do other five equilibrium design as required.

Wear by an axis 60 between connecting base 20 and the rotary seat 10 and be connected, have the face of scabbling 61 at least on this axis 60, and the shape of the attachment hole 11 of rotary seat 10, size and axis 60 couplings, the attachment hole 21 of connecting base 20 is circular, and with axis 60 be Spielpassung, thereby realize relatively rotating.Connecting base 20 upsides, the outer rim position that is positioned at its attachment hole 21 convex with salient point 22, and salient point 22 cooperates with limit structure 62 on the axis 60.In the present embodiment, 2 spacing points of the limit structure 62 on the axis 60 are 180 ° of angle settings, promptly realize 180 ° of deflections of fluorescent screen, the convenient use.

Fixed base 40 is used to connect the base of notebook computer, liquid crystal screen (CD, VCD, DVD player) or LCD TVs, and connecting base 20 is connected with fluorescent screen on notebook computer, liquid crystal screen (CD, VCD, DVD player) or the LCD TVs.Beat and to open or close that to close the fluorescent screen be to rotate by rotary seat 10 to realize that the overhanging end of the pivot joint bearing pin 30 of combination is connected with eccentric structure 50 on rotary seat 10 two ends, wherein the roulette wheel on this eccentric structure 50 52 is with to articulate bearing pin 30 synchronous, and another positioning wheel 51 is motionless relatively.During rotary seat 10 rotations, articulate bearing pin 30 and follow rotation, thereby drive roulette wheel 52 rotations of eccentric structure 50, junction plane between roulette wheel 52 and the positioning wheel 51 has ripple arc embedded structure, be the roulette wheel 52 crest convex arc 512 relative dislocation slips on the trough concave arc 521 on it and the positioning wheel 51 when rotating, when the crest convex arc 512 on the positioning wheel 51 slides into next trough concave arc 521 on the roulette wheel 52, the action of taking advantage of a situation and gliding is arranged, and finally be embedded in the bottom of this trough concave arc 521, realize beating to open or close automatically and closing of fluorescent screen.

The characteristic of utilizing connecting base 20 to rotate relative to rotary seat 10, the fluorescent screen that is connected can be made multi-angle rotates, when axis 60 rotates, the salient point 22 that be arranged on connecting base 20 upsides, is positioned at the outer rim position of its attachment hole 21 cooperates with limit structure 62 on the axis 60, realizes the rotation positioning of fluorescent screen.

The utility model in assembling process, also corresponding some shell fragments of increase or pad at the connection part place, its structure is an ordinary construction, also just gives unnecessary details no longer one by one at this.
