Specific embodiment
Referring to the drawings.High pulling torque rotating shaft mechanism provided by the utility model, including base 1, rotatable upper casing 2, turn Axle 3, moment of torsion enlarger, the rotating shaft 3 are arranged on base 1, and the upper casing 2 passes through moment of torsion enlarger and the rotating shaft 3 It is connected, and upper casing 2 is in the amplification output end of moment of torsion enlarger, the rotating shaft 1 is in the generation moment of torsion of moment of torsion enlarger This one end, the rotating shaft mechanism be provided with to the rotating shaft 3 apply moment of torsion mechanism, produced moment of torsion is through moment of torsion enlarger The amplification transmission of structure so that effect becomes big with the moment of torsion of upper casing 2, according to magnification ratio, can with several times, amplify torsion decades of times Square.If setting touch-screen in the upper casing 2, when upper casing 2 frequently bears touch operation impact, or the weight of upper casing 2 is larger When, no matter what angle upper casing 2 turns to, also can immediately be positioned when rotating and stopping,
The pivot A of the upper casing 2 is in outside the upper end of upper casing 2.
The rotating shaft mechanism is provided with two sets of the left and right moment of torsion enlarger for being in the two ends of rotating shaft 3 respectively, and the moment of torsion is put Great institutions include the gear wheel 41 and little gear 42 of engagement, and its diameter proportion is 10:1, moment of torsion amplifies 10 times.The rotating shaft 3 is Pinion shaft, the upper casing 2 and gear wheel 41 are connected, and the center of circle of the gear wheel 41 is the center of rotation of upper casing.
The mechanism that the countershaft applies moment of torsion is bag in the outer non-rotatable edge rolling 5 of fixation of rotating shaft 3.
The gear wheel 41 is arc rack, and is provided with circular arc spacing hole 410 or groove wherein, be located on base 1 with The center of circle of the locating part 61 that circular arc spacing hole 410 or groove are slidably matched, the circular arc spacing hole 410 or groove is the circle of gear wheel 41 The heart, the base 1 is provided with guide roller 7 outside arc rack.
