Description

A hinge to prevent shaking

technical field

The utility model relates to a hinge device for preventing swaying, which refers to a hinge device arranged between an upper cover and a base of a flipping device for making the upper cover rotate relative to the base.

Background technique

Flip-top devices, such as notebook computers and mobile phones, have opposite upper covers and bases, and a hinge is provided between the upper cover and the base so that the upper cover can be opened or closed relative to the base. In addition to enabling the upper cover to be opened or closed relative to the base, the cover device also needs to enable the upper cover to rotate relative to the base. The hinge device in the prior art has a rotating shaft and a fixed shaft that are pivotally connected to each other. are fixed to each other, the fixed shaft and the base are fixed to each other, and the upper cover is rotated relative to the base by rotating the rotating shaft relative to the fixed shaft. When the rotating shaft rotates, due to the weight of the screen or the uneven force applied by the user, the fixed shaft will be tilted relative to the rotating shaft, and the screen will vibrate accordingly, causing troubles to the user.

Contents of the invention

In view of the above-mentioned shortcomings of the prior art, the utility model improves the hinge device of the prior art, so that when the screen rotates relative to the base, no shaking occurs.

In order to achieve the above-mentioned purpose of the utility model, the utility model designs a hinge device for preventing the screen from shaking, which includes:

A central support frame, which has a bottom plate, and a first side wing and a second side wing respectively extending toward the bottom side of the bottom plate and formed on both ends of the bottom plate, and two side ribs are respectively extended and formed on the two edges of the bottom plate and the two ends adjacent to the bottom side;

An opening and closing shaft group, which is connected with the two side wings of the center support frame. The opening and closing shaft group has a stop rod, a connecting support frame, a fixing piece, a fixed shaft and a limit support frame. In the first side wing of the center bracket, the connecting bracket is sleeved on the stop bar, the fixing piece is sleeved and fixed at the end of the stop bar, the fixed shaft is passed through the second side wing of the center support frame, and the limit bracket is sleeved on a fixed shaft;

A rotating shaft group, which is connected to the bottom plate of the center support frame. The rotating shaft group includes a rotating shaft and a fixed support frame. The rotating shaft is passed through the bottom plate of the center supporting frame. The crown is relatively attached to the side ribs of the bottom plate of the center support frame, and the fixed support frame is sheathed and fixed on the end of the rotating shaft.

When in use, fix the connecting bracket and the limit bracket of the opening and closing shaft group and the base of the flipping device to each other, and fix the fixed bracket of the rotating shaft group and the upper cover of the flipping device to each other. When the axis rotates, the upper cover rotates relative to the base. At this time, the upper cover drives the rotating shaft to rotate relative to the center support frame. If there is no side rib, the rotating shaft is supported by the side rib of the center support frame and does not shake relative to the center support frame, so the upper cover can remain stable and not shake when it rotates relative to the base.
