Abstract

The utility model relates to a pivot device which comprises a plurality of tubular spring leaves which penetrate into a sleeve barrel of a fixing and supporting frame, wherein each tubular spring leaf is fixed in a positioning groove of the fixing and supporting frame by a fixing part, and the pivot shaft penetrates into each tubular spring leaf. The fixing and supporting frame is mutually fixed with a bottom seat of a cover lifting device, the pivot shaft is mutually fixed with an upper cover of the cover lifting device. When the upper cover rotates correspondingly to the bottom seat, the pivot shaft can be driven to correspondingly rotate in each tubular spring leaf, and thus, a frictional area between the pivot shaft and each tubular spring leaf are enlarged by the arrangement of the tubular spring leaves so as to enhance relative frictional force. Accordingly, the pivot device can provide high torque force, and the upper cover can stably stop on an angle which is needed.

Description

Pivot device

Technical field

The utility model relates to a kind of pivot device, particularly relates between a kind of loam cake and base that is installed in lid-lifting device, with so that loam cake is able to the pivot device with respect to the base rotation.

Background technique

Lid-lifting device (notebook computer for example, all be equiped with pivot device between loam cake translating machine etc.) and base, so that loam cake must be opened and closure with respect to base, according to prior art, have the pivot device of multiple different structure, wherein a kind of pivot device of prior art is shown in No. the 420321st, TaiWan, China patent announcement, it has spoon rack and wears and be fixed in the joining hole of fixed base, pivot is located in the spoon rack, fixed base and pivot interfix with the loam cake and the base of lid-lifting device respectively, when then loam cake rotates with respect to base, pivot is with respect to fixed base and spoon rack rotation, make pivot outer wall and spoon rack internal face produce friction and formation torsion, this torsion provides pivot to stagnate power, then do not pull under the situation of loam cake the user, the unlikely pivot that makes of the weight of loam cake is with respect to fixed base and spoon rack rotation, yet, the pivot device of prior art only has two integrated spoon racks, the torsion that can provide is limited, generally be applied in the pivot device on the notebook computer, when the screen size of notebook computer is big more, the weight of its loam cake is heavy more, then the torsion that pivot device provided of prior art is not enough to force pivot to stagnate easily, loam cake can force pivot to rotate with respect to base because of the weight of itself, make the user can't be by the torsion between pivot and spoon rack, loam cake is stuck in required angle, so the pivot device of prior art really has its inconvenience in the use.

This shows that above-mentioned existing pivot device obviously still has inconvenience and defective, and demands urgently further being improved in structure and use.In order to solve the problem that pivot device exists, relevant manufacturer there's no one who doesn't or isn't seeks solution painstakingly, but do not see always that for a long time suitable design finished by development, and common product does not have appropriate structure to address the above problem, this obviously is the problem that the anxious desire of relevant dealer solves.Therefore how to found a kind of pivot device of new structure, just become the current industry utmost point to need improved target.

Because the defective that above-mentioned existing pivot device exists, the design people is based on being engaged in this type of product specification manufacturing abundant for many years practical experience and professional knowledge, and the utilization of cooperation scientific principle, actively studied innovation, in the hope of founding a kind of pivot device of new structure, can improve general existing pivot device, make it have more practicability.Through constantly research, design, and after studying sample and improvement repeatedly, create the utility model that has practical value finally.
