A rotating component in the inner ratchet-pair of described rotating machinery bidirectional ratchet 15 is connected mutually with described rotating machinery horizontal axis 14, another rotating component is then connected mutually with rotating machinery rotation foot treadle 19 (these structures and install the known technology also passed through very much for bidirectional ratchet commodity, therefore do not repeat).Also comprise rotating machinery rotation foot treadle reduction torsion spring 21, its one end is functionally connected with rotating machinery rotation foot treadle 19, and the other end is then connected with described outer sleeve 2 or base 1; Automatically reseting after stepping on for described rotating machinery rotation foot treadle 19 pin.
Of the present invention to realize principle as follows: when specifically using, such as need lifting display device, first with kicking or step on the elevator mechanism bidirectional ratchet throw over switch 16 stirred on described elevator mechanism bidirectional ratchet 9---pin plate bar selects one of switching two single direction rotation directions, the described elevator mechanism bidirectional ratchet 9 of the unidirectional turn of elevator mechanism rotation foot treadle 17 (supposing forward) described in reciprocating pedal again, described elevated levels axle 8 is driven to rotate by described elevator mechanism bidirectional ratchet 9 again, then one of them elevator mechanism helical gear 7 is driven together to rotate, thus drive another elevator mechanism helical gear 7 be meshed and the described screw rod 5 be connected mutually also and then to rotate again, thus order about described transmission nut 4 and be elevated (not rotating) and described inner sleeve 3 and display device (not shown in FIG.) one is elevated.Otherwise when falling screen, by another single direction rotation direction manually kicking or step on elevator mechanism bidirectional ratchet throw over switch 16 and select to switch described elevator mechanism bidirectional ratchet 9, the unidirectional turn of elevator mechanism rotation foot treadle 17 described in reciprocating pedal again (supposing oppositely) described elevator mechanism bidirectional ratchet 9, the revolving part also and then counterrotating of corresponding follow-up mechanism, thus realize display device decline.It is more convenient that described elevator mechanism rotation foot treadle reduction torsion spring 20 makes described elevator mechanism rotation foot treadle 17 self-return (also having certain power-assisted effect in addition when reverse) make it operation after reciprocal pin steps on described elevator mechanism rotation foot treadle 17.
When needing rotating display device, first with kicking or step on the rotating machinery bidirectional ratchet throw over switch 18 stirred on described rotating machinery bidirectional ratchet 15---pin plate bar selects one of switching two single direction rotation directions, the described rotating machinery bidirectional ratchet 15 of the unidirectional turn of rotating machinery rotation foot treadle 19 (supposing forward) described in reciprocating pedal again, described rotating machinery horizontal axis 14 is driven to rotate by described rotating machinery bidirectional ratchet 15 again, then one of them rotating machinery helical gear 13 is driven together to rotate, thus drive another rotating machinery helical gear 13 be meshed and the described sun gear 10 be connected mutually also and then to rotate again, thus drive planetary pinion 11 to rotate, and then order about ring gear 12 and outer sleeve 2 and display device (not shown in FIG.) and integrally rotate forward.During counterrotating, by another single direction rotation direction manually kicking or step on rotating machinery bidirectional ratchet throw over switch 18 and select to switch described rotating machinery bidirectional ratchet 15, the unidirectional turn of rotating machinery rotation foot treadle 19 described in reciprocating pedal again (supposing oppositely) described rotating machinery bidirectional ratchet 15, the revolving part also and then counterrotating of corresponding follow-up mechanism, thus realize the counterrotating of display device.It is more convenient that described rotating machinery rotation foot treadle reduction torsion spring 21 makes described rotating machinery rotation foot treadle 19 self-return (also having certain power-assisted effect in addition when reverse) make it operation after reciprocal pin steps on described rotating machinery rotation foot treadle 19.
Rise because the present invention have employed when bidirectional ratchet mechanism that the industry never adopted solves Pedals type lifting thus and rotates in desktop display bracket and fall the difficult problem needing foot-operated both direction to rotate respectively, achieving the support frame structure of real practicable pedal lifting and rotating display device.Thoroughly overcome shaking type and DYN dynamic number of drawbacks, display device is (often containing table border or backing, in-built screen) though very heavy, but phase opponent obvious human leg-driven strength is much bigger, pin is stepped on more natural than hand, take advantage of a situation, greatly can save muscle power also more convenient, sensation is required great effort hardly, because strength of one's legs is large, therefore also can reduce reduction speed ratio further thus make lifting and spinning movement faster, separately because foot-driven machine structure is arranged on bottom, whole human body completely no longer needs to bend over, directly trample, operate lighter, action also seems that more " gentleman " feels, make the lifting integrated operation of display screen more natural, calm and graceful.In addition pin steps on the position that transmission device just can be utilized originally just need to be arranged on least significant end, drive mechanism also the most directly, simply, no longer need extra transmission link to top, further simplify mechanism, overall cost is also lower, particularly the descending operation mechanism position of exposed parts is unremarkable in bottom, more hidden, and outward appearance looks more natural, sensation is better.
The present invention of this external cause has superposed the function that in supporting frame, outer sleeve 360 degree rotates, therefore makes this supporting frame be suitable for this being had to required displaying place, has enriched use occasion and the scope of this type of desktop display bracket greatly.
Certain above-described embodiment, only for technical conceive of the present invention and feature are described, its object is to person skilled in the art can be understood content of the present invention and implement according to this, can not limit the scope of the invention with this.All modifications done according to the Spirit Essence of main technical schemes of the present invention, all should be encompassed within protection scope of the present invention.
