Description

hub

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 rotate relative to the base.

Background technique

General mobile phones, translators and notebook computers mostly have two parts, an upper cover and a base, and a hinge is provided between the upper cover and the base to make the upper cover open or close relative to the base. However, with the advancement of technology, mobile phones And notebook computers have added many additional functions, such as mobile phones with camera functions, etc. The upper cover can only be opened or closed relative to the base and cannot effectively perform various additional functions. Therefore, the conventional hub device does have the necessity of improvement .

Utility model content

In view of the lack of function of the aforementioned conventional hinges, the utility model is to design a rotary hinge, so that the upper cover can rotate relative to the base, so that the additional functions of the covered items can be fully utilized, and at the same time increase the number of covered items Ease of use.

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 base plate, on which a perforation is formed, and the periphery of the perforation is formed with two relatively outwardly extending protrusions;

A pivot, which is hollow columnar, is fixed in the through-hole of the bottom plate, and two opposite through-holes are formed on the side wall of the pivot;

A swivel seat, which includes a C-shaped ring-shaped bushing. The two ends of the bushing extend outwards to form a fixed part. The bushing is formed with a perforation on the wall opposite to the two ends. The bottom edge is formed with a protrusion extending outward, and the sleeve is clamped on the outside of the pivot;

a ball;

A ring piece, which is clamped on the outside of the bushing, and the two ends of the ring piece are against the junction of the bushing and the fixed part of the rotating seat. The side wall of the ring piece is formed with a perforation, and the ball is located between the ring piece and the bushing. And the ball fits with the perforation of the axle sleeve and the perforation of the ring piece, the diameter of the perforation of the axle sleeve is larger than the diameter of the ball, the diameter of the perforation of the ring piece and the diameter of the pivot are smaller than the diameter of the ball.

The bottom plate is fixed on the base of the covered object, and the fixed part of the rotating seat is fixed on the upper cover of the covered object. When the upper cover is rotated, the rotating seat and the ring piece hold the ball and rotate together, and the ball rotates to match the perforation of the pivot. Fitting, in order to achieve the positioning function.

The utility model has the advantage that the utility model is arranged between the base and the upper cover of the covered object, so that the upper cover can rotate relative to the base, so as to increase the convenience of use, and at the same time, the function of the object can be fully exerted.

Detailed ways

Please refer to FIG. 1 and FIG. 2 , the utility model includes a bottom plate 10 , a pivot 20 , a swivel seat 30 , a ball 40 , and a C-shaped ring 50 .

A non-circular perforation 11 is formed on the aforementioned bottom plate 10 . The inner walls of both sides of the perforation 11 are formed with opposite planes 111 . The periphery of the perforation 11 is formed with two relatively outwardly extending protrusions 12 .

The aforementioned pivot 20 is in the shape of a hollow column, and the bottom end of its outer wall is formed with two opposite planes 21. The pivot 20 is inserted in the non-circular perforation 11 of the bottom plate 10 through the planes 21, and the pivot 20 is fixed on the bottom plate 10. Above, two opposite perforations 22 are formed on the side wall of the pivot 20 , and a ring flange 23 is formed on the top of the pivot 20 .

The aforementioned swivel seat 30 includes a C-shaped ring-shaped bushing 31, the two ends of the bushing 31 extend outwards to form a fixed part 32, and the wall surface of the bushing 31 opposite to the two ends is formed with a perforation 311, the bushing 31 A protruding portion 312 extending outward is formed on the bottom edge of the wall opposite to the through hole 311 , the bushing 31 is clamped outside the pivot 20 , and the ring flange 23 of the pivot 20 abuts against the top edge of the bushing 31 .

The aforementioned ring piece 50 is clamped on the outside of the shaft sleeve 31, and the two ends of the ring piece 50 abut against the connection between the shaft sleeve 31 and the fixed part 32 of the rotating seat 30. The side wall of the ring piece 50 is formed with a perforation 51, and the ball 40 is located Between the ring piece 50 and the bushing 31, and the ball 40 fits with the perforation 311 of the bushing 31 and the perforation 51 of the ring piece 50. The diameter of the diameter and the diameter of the through hole 22 of the pivot shaft 20 are smaller than the diameter of the ball 40 .

Please refer to FIG. 3 , the bottom plate 10 of the hub is fixed on the base 60 of the notebook computer, and the fixing portion 32 of the swivel base 30 of the hinge is fixed on the top cover 70 of the notebook computer.
