hub

technical field

The utility model relates to a hinge device, which is installed between the upper cover and the base of an article with a cover, so that the upper cover and the base are relatively opened and closed.

Background technique

General covered items include notebook computers, mobile phones, and translators, etc., which all include a top cover and a base. The existing hinge device is shown in the case of "Segmented Hub Structure" in Chinese Patent Announcement No. 452106. It allows the upper cover to be opened and closed relative to the base, and at the same time provides a positioning effect when opening and closing, but it includes quite a lot of components, which makes the manufacturing cost high and the assembly time-consuming and complicated.

Utility model content

In view of the shortcomings of the aforementioned existing hinges, the utility model is to design a hinge with fewer components, which provides positioning of the upper cover relative to the base when it is opened and closed, while reducing manufacturing costs and simplifying the assembly process.

In order to achieve the above-mentioned creation purpose, the utility model is to design a kind of hinge device, which is characterized in that it includes:

A pivot, which is a rod with a non-circular cross-section, one end of the pivot has a head, and the other end of the pivot is provided with threads;

A fixing plate, which includes a fixing part and a pivot part, a hook part is formed at the end of the pivot part, a non-circular perforation is formed through the pivot part, and the pivot part is sleeved on the pivot through the perforation;

A positioning piece, on which a non-circular perforation is formed, the positioning piece is sleeved on the pivot shaft through the perforation, and the two ends of the positioning piece are respectively formed with a first convex portion and a second convex portion extending axially;

A rotating piece, which includes a fixed part and a positioning part. A circular central perforation is formed through the positioning part. The positioning part is sleeved on the pivot by the perforation. The first positioning perforation and the second positioning perforation corresponding to the first convex part of the positioning piece are respectively formed on the peripheral edge of the perforation part, and the third positioning perforation and the fourth positioning perforation are formed relative to the second convex part. The angle between the line connecting the first positioning perforation and the third positioning perforation is equal to the angle between the line connecting the first protrusion and the second protrusion, and the angle between the line connecting the second positioning perforation and the fourth positioning perforation is equal to the angle between the first protrusion and the second protrusion. The included angle of the line connecting the two convex parts;

A number of gaskets, which are sleeved on the pivot;

A fixed nut is screwed on the threaded portion at the end of the pivot.

The fixed plate is fixed on the base, and the rotating piece is fixed on the upper cover, so that the upper cover can be opened and closed relative to the base, and the positioning effect is achieved by fitting the convex part of the positioning piece with the positioning perforation of the rotating piece.

The utility model has the advantage that the upper cover can be rotated relative to the base with fewer components, and at the same time can achieve a positioning effect, which not only saves manufacturing costs, but also makes the assembly process simple.

The aforementioned fixing plate 20 includes a fixing portion 21 and a pivoting portion 22. The end surface of the pivoting portion 22 is arc-shaped and a hook portion 221 is formed at the end, and a non-circular perforation 222 is formed through the pivoting portion 22. The portion 22 is sheathed on the pivot shaft 10 through the through hole 222 .

A non-circular perforation 31 is formed through the aforementioned positioning piece 30, the positioning piece 30 is sleeved on the pivot 10 through the perforation 31, and the two ends of the positioning piece 30 are respectively formed with a first convex portion 32 and a second convex portion 33, The angle between the line connecting the two convex parts 32 and 33 is 180 degrees and runs through the center of the through hole 31 .

The aforementioned rotating piece 40 includes a fixed part 41 and a positioning part 42. A circular central perforation 421 is formed through the positioning part 42. The positioning part 42 is sleeved on the pivot 10 through the perforation 421. The positioning part 42 is formed near the peripheral edge. There is an arc-shaped track 422, and the positioning portion 42 is formed with a first positioning perforation 423 and a second positioning perforation 424 corresponding to the first protrusion 32 of the positioning piece 30 on the periphery of the perforation 421, and is formed with a second positioning perforation 424 respectively.
