The face that contacts with friction pads on the bolt head described in
the present invention preferably is processed to coarse rubbing surface, with the frictional force between further enhancing bolt head and the friction pads.
Compression spring all is sandwiched between nut and the connecting base described in
the present invention, and compression spring also can be sandwiched between connecting base and the connecting plate certainly, but a kind of fit before among the present invention preferably still being.
Be processed with the axis hole that supplies screw rod to pass described in
the present invention on the connecting base, said screw rod bottom is that non-rotation cooperates with this axis hole.
cooperate with the non-rotation of axis hole in order to ensure the screw rod bottom; In a kind of scheme; The present invention is processed with at least one straight bevel on the cylindrical segment of said screw rod bottom, and the axis hole shape on the connecting base and this cylindrical segment sectional shape coupling.
also can the polygonal that N>=3 are counted on the limit be processed in said screw rod bottom section among the present invention, and axis hole shape and polygonal on the connecting base are complementary certainly in another kind of scheme.
are further, and the angular positioning when realizing mechanism's rotation is fixed with the angle limiting stopper on said connecting base among the present invention, then be provided with the angle restraining groove that supplies the angle limiting stopper movable on the said connecting plate.
in order further to strengthen frictional force, the bottom of connecting base described in the present invention is fixed with friction washer, and said friction washer is sandwiched between connecting base and the connecting plate.
are the same with routine techniques; Said connecting base is an aluminum casting; Have some positioning holes on it, be used for fixing through the holder part on screw and LCD TVs or the display screen, connecting plate then is a sheet metal; Also have some positioning holes on it, be used for fixing through the base portion of screw and support.During concrete the use, the user rotates LCD TVs or display screen, drives the relative connecting plate of connecting base and rotates, and realizes spinfunction.Mechanism of the present invention is in rotary course, and frictional force results from bolt head and friction pads, and between friction washer and the connecting plate, total frictional force is above-mentioned two-part frictional force sum, and compression spring provides pretightening force, increases friction torque.Angle limiting stopper on the connecting base matches with angle restraining groove on the connecting plate, thereby limits the angle of swing of connecting base, and angle is specifically decided according to the design radian of angle restraining groove, is generally ± 15o.
this LCD TVs support rotating machinery provided by the invention; Through bolt and connecting base are fixed; And between bolt head and connecting plate, be encased inside friction pads; Make original concentrating result from the frictional force between connecting base and the connecting plate, part has been transferred between bolt head and the connecting plate, does the use that can reduce even cancel friction pads between connecting base and the connecting plate like this.And in further technological scheme; The present invention contacts bolt head with friction pads surface Machining becomes coarse rubbing surface, minimizing further the friction pads usage quantity between bolt head and the connecting plate, simplified mechanism greatly; Simplify assembling, reduced cost.
Advantage of the present invention is:
this LCD TVs support rotating machinery provided by the invention is compared existing technology, has reduced the use of friction pads, has simplified mechanism greatly, has simplified assembling, has reduced cost.
