Technical field
The utility model relates to support device of tablet personal computer, specifically a kind of Flat computer support frame.
Background technique
At present, panel computer is because its portable and powerful function obtains more and more people's favor, because the size of panel computer is between mobile phone and notebook computer, people are hand-held when using, and hand is felt fatigue easily, and panel computer mostly is equipped with support for this reason.
Existing Flat computer support frame generally includes dunnage and base plate, dunnage and base plate are rotationally connected, base plate is provided with for the curve bath that offsets with the panel computer lower end away from the end at the place of being rotationally connected, during use, dunnage is amounted to and is had a certain degree, support is realized support to panel computer by the curve bath on base plate, dunnage and the base plate, but because the plate body of panel computer is comparatively smooth, the stationarity of dunnage is poor, can't locate comparatively exactly, the panel computer of placement is fallen down suddenly.
Summary of the invention
Technical problem to be solved in the utility model is: provide a kind of dunnage stationarity stronger, the Flat computer support frame that can accurately locate.
Technical solution adopted in the utility model is: a kind of Flat computer support frame is provided, comprise dunnage and base plate, described dunnage and base plate are rotationally connected, base plate is provided with for the curve bath that offsets with the panel computer lower end away from the end at the place of being rotationally connected, the described place of being rotationally connected is provided with for fixed support plate amounts to the positioning device of angle with maintenance, and described positioning device is located on dunnage and the base plate.
Described positioning device comprises the first positioning wheel, the second positioning wheel and spring, and described the first positioning wheel and spring are located on the dunnage, and the second positioning wheel is located on the base plate.
Described the first positioning wheel is two, and the second positioning wheel is two.
Described the first positioning wheel and spring are located on the dunnage, the second positioning wheel is located on the base plate and refers to, one end of described dunnage is provided with the first horizontal through hole, axial sliding fit is at the two ends of the first through hole respectively for described two the first positioning wheels, and described spring is located between two the first positioning wheels and two ends and two the first positioning wheels offset; The corresponding end of described base plate is provided with the second through hole and third through-hole, the first through hole is located between the second through hole and the third through-hole and three's coaxial line, described two the second positioning wheels are respectively in axial sliding fit the second through hole and the third through-hole, and the second positioning wheel respectively tooth by being located at its end and the first positioning wheel in the first through hole is meshed.
After adopting above structure, the utility model Flat computer support frame is compared with existing technology, following advantage is arranged: because dunnage and base plate are respectively equipped with the first positioning wheel and the second positioning wheel that is meshed, amount to when dunnage and to have a certain degree when panel computer supported, intermeshing the first positioning wheel and the second positioning wheel can by between the tooth mutually against, dunnage is fixed preferably; When needing dunnage to amount to into different angles, pull dunnage with hand, the tooth of the first positioning wheel in the first through hole of dunnage under the effect of pull force and the tooth surface of the second positioning wheel on the base plate slide, because the first positioning wheel and spring offset, spring is compressed, make dunnage realize comparatively easily rotating, when arriving suitable amounting to after angle lets go, spring resets under elastic reaction again, compress first positioning wheel at two ends, tooth on the first positioning wheel again can with base plate on the tooth of the second positioning wheel mesh together, fix dunnage, can reach comparatively accurately location.
As improvement, the interior also axial sliding fit of described the second through hole and third through-hole has gland and bearing pin, one end and the gland of described bearing pin offset, the other end of bearing pin and the first positioning wheel offset, gland and bearing pin are set, thereby can make bearing pin compress the first positioning wheel by the extruding gland, intermeshing the first positioning wheel is separated with the second positioning wheel, can better carry out the adjustment that dunnage is amounted to angle.
As further improvement, described base plate is provided be used to the microscler through hole that holds dunnage, when support does not use, is placed in this through hole after dunnage is rotated, and reduces the shared space of support.
As further improving, the surface of described curve bath is provided with the arc gum cover for the protection of panel computer, can avoid support to the scuffing of panel computer.
As more further improving, the back side of described curve bath is provided with for anti-skidding projection, can play anti-skidding effect to support.
