technical field

The utility model relates to a hinge device, which refers to a hinge device installed between an upper cover and a base of an article with a cover, so that the upper cover can be relatively opened or closed on the base.

Background technique

General mobile phones, translators and notebook computers mostly have two parts, the upper cover and the base, and a hinge is provided between the upper cover and the base to make the upper cover relatively open or close to the base. The commonly used hinge has a convex positioning There is a set of convex parts on the convex positioning block, and a set of corresponding concave parts on the concave positioning block. When the convex parts and the concave parts are fitted, the hinge provides a positioning effect to make the upper cover relatively There is no collision when the upper cover is closed to the base, but when the upper cover is opened relative to the base, some hinges do not provide positioning functions, so that the upper cover cannot be positioned at any angle, while some hinges use the same set of convex and concave parts to provide positioning functions. The upper cover and the base will form a 180-degree angle. For users of translators and notebook computers, the 180-degree angle between the upper cover and the base will cause inconvenience to the users.

Utility model content

In view of the above-mentioned conventional shortcomings, the utility model is to improve the hinge, so that the positioning angle of the upper cover relative to the base when it is opened can be changed according to different product requirements during manufacture.

In order to achieve the above-mentioned purpose of the utility model, the technical means adopted in the utility model is to design a hinge device, which includes:

a pivot;

A concave positioning block, the center of which is perforated with a perforation. The concave positioning block is divided into an inner ring that is closer to the center point of the perforation in the radial direction and an outer ring that is farther from the center point of the perforation in the radial direction. Located on the pivot, one side of the concave positioning block is located on the inner ring to form a first concave part and a second concave part, and a third concave part and a fourth concave part are formed on the outer ring. The two ends of the concave part are formed with slopes, and the center of the first concave part The line coincides with the center line of the third recess, and the center line of the second recess coincides with the center line of the fourth recess;

A convex positioning block, which is radially closer to the center point of the perforation, includes an inner ring that is radially closer to the center point of the perforation and two relatively outwardly protruding outer rings that are farther radially from the center point of the perforation The convex positioning block is sleeved on the pivot shaft through the perforation. One side of the convex positioning block is located on the inner ring to form a first convex part corresponding to the first and second concave parts, and a convex part is formed on the outer ring corresponding to the third and fourth concave parts. The second convex part of the concave part has inclined surfaces formed at both ends of the convex part, and the centerline of the first convex part coincides with the centerline of the second convex part;

A shaft sleeve, which is hollow and has different openings at both ends. There are gaps formed on the two opposite side walls relative to the outer ring of the convex positioning block. The outer ring of the convex positioning block fits in the slot. It is located on the pivot and one end of the pivot is provided with a ring groove extending out and fixed on the other side of the sleeve;

A spring is located in the shaft sleeve and sleeved on the pivot shaft, and the two ends of the spring are respectively pressed between the inner wall of the shaft sleeve and the convex positioning block.

The advantage of the utility model is that only the recess on the concave positioning block can be changed without changing any other components, so that the upper cover and the base of the installed object can not only have a positioning function when closed, Whether or not the centerlines of the first and third recesses coincide with the centerlines of the second and fourth recesses can be changed to change the positioning angle of the upper cover relative to the base when it is opened.
