Detailed ways

Please refer to Fig. 1 to Fig. 4, the hinge device of the present invention is arranged between the main body 6 of the electronic equipment and the camera lens 7 provided with screw holes, and it includes:

The fixed seat 1 has a support frame 11 connected to the main body 6 and a hollow ring piece 12 formed on the support frame 11. Two engaging grooves 121 are provided on the left and right sides of the outer edge of the hollow ring piece 12. The position of the inner edge of the engaging groove 121 is respectively provided with a pressing piece 122 bent towards one side, and the position directly below the hollow ring piece 12 near the support frame 11 is provided with a limit block 123 bent towards the other side;

The pivoting ring block 2 is provided on one side where the limit block 123 of the fixed seat 1 is bent, and on the outside of the pivoting ring block 2 from one end relative to the fixed seat 1 to the other end, there are engaging parts in sequence. 21. The pressing part 22, the limiting part 23 and the joint part 24, the outer side of the engaging part 21 is provided with three engaging protrusions 211, and the pressing part 22 passes through the hollow ring piece 12 of the fixing seat 1, And tightly pressed between the pressing pieces 122 on both sides, so that the pivoting ring block 2 and the fixed seat 1 are not easy to fall off and increase the frictional resistance. The limiting protrusion 231 of the joint part 24 is provided with a joint protrusion 241 on which the photographic lens 7 is engaged. In addition, the inner side of the pivot ring block 2 is provided with an axially penetrating pivot and a line passing through it. The perforation 26, the pivot connects the camera lens 7 and the pivot ring block 2, so that the camera lens 7 and the pivot ring block 2 rotate together. The pivot is a detachable screw 251, so the pivot ring block 2 is also provided with There is a screw hole 25 for the screw 251 to be screwed in. Since the photographic lens 7 is also provided with a screw hole, the screw 251 can combine the pivoting ring block 2 and the photographic lens 7 to be screwed;

The elastic component 3 is arranged between the limiting part 23 and the hollow ring piece 12 to increase the torque when the pivot ring block 2 rotates and reduce the wear between the components. The elastic component 3 can be a hollow ring gasket ;

The reed 4 is arranged on the side of the fixed seat 1 that is bent relative to the pressing piece 122. It is hollow, and the inner edge is provided with a receiving groove 43 for positioning the pressing piece 122 relative to the position of the pressing piece 122. , and the outer edge of the reed 4 is provided with a fixed piece 41 relative to the engaging groove 121 to clamp and fix the reed 4 and the fixed seat 1. In addition, on the other side of the reed 4 relative to the fixed seat 1, a Positioning bump 42;

The positioning ring piece 5 is arranged on the other side of the reed 4 relative to the fixed seat 1. The above-mentioned engaging portion 21 is locked in the positioning ring piece 5, and its inner edge is opposite to the three sides of the engaging portion 21. The engaging protrusion 42 is provided with three engaging grooves 51, so that the pivoting ring block 2 and the positioning ring piece 5 can be engaged with each other more firmly, and rotate together with the positioning ring piece 5 and the camera lens 7, the positioning The outer edge of the ring piece 5 is provided with four positioning grooves 52 at angles of 0, 90, 180 and 270 degrees relative to the positioning protrusion 42, so that the positioning protrusion 42 enters the positioning groove 52 to achieve the positioning effect.

Since the support frame 11 of the fixed base 1 is fixed on the body 6, and the hollow ring piece 12, the elastic component 3 and the reed 4 are fixed to each other, the pivot ring block 2, the positioning ring piece 5 and the camera lens 7 are connected through the pivot shaft. , and allow these three components to rotate simultaneously with the camera lens 7, thereby allowing the camera lens 7 and the body 6 to rotate relative to each other.

The quantity of the limiting protrusions 231 in the above-mentioned pivoting ring block 2 can be two, and the angular range of the positions where the two limiting protrusions 231 are set determines the angular range that the pivoting ring block 2 can rotate. The implementation method is the same as the above-mentioned arc-shaped limiting protrusion 231 .

In addition, the limit projection 231 in the above-mentioned pivoting ring block 2 can be an arc-shaped block, and the angle between the two ends of the arc-shaped block determines the angle at which the pivoting ring block 2 can rotate. When the swivel block 2 rotates in one direction, the arc-shaped limiting protrusion 231 also rotates thereupon, and when one end of the arc-shaped limiting protrusion 231 interferes with the limiting block 123, the rotation stops, and the pivot When the ring block 2 rotates in the other direction, the other end of the arc-shaped limiting protrusion 231 will touch the limiting block 123, and the rotation will stop immediately, so the effect of bidirectional limiting can be achieved.

Please refer to Fig. 2, Fig. 5 to Fig. 7, the top and bottom of the hinge are respectively provided with a limit protrusion 231, when the pivot ring block 2 rotates, the upper limit protrusion 231 turns to the bottom, and When it is stuck on one side of the lower limit block 123, the limit effect can be achieved. When the pivot ring block 2 rotates from the other direction, the lower limit protrusion 231 is stuck against the other side of the lower limit block 123. When it is on the side, it can also achieve the effect of limiting, and the two limiting protrusions 231 can make the hinge achieve the effect of bidirectional limiting.

Please refer to Fig. 3, Fig. 4 and shown in Fig. 8, the body 6 of electronic equipment is a recording pen with screen 61, and the hinge device of the present utility model is arranged on the side that camera lens 7 is connected with body 6, by this The hinge can turn the lens from one direction to the other, so that the user can operate while seeing the screen 61 when taking selfies or taking pictures of others. Although there is an elastic component 3 to increase the torque when twisting, the utility model can further utilize the cooperation of the positioning protrusion 42 and the positioning groove 52 on the positioning ring piece 5, so that the lens can be positioned at 0 degrees, 90 degrees and 180 degrees. The positioning is performed so that the user does not have to worry about the lens being rotated due to weight or slight external impact.

Through the combination of the above components, the utility model provides a hinge that can be limited in two directions and can be positioned at several angles. When the pivot ring block rotates, only the positioning ring piece will rotate accordingly. The limiting portion of the pivoting ring block is provided with a limiting projection which will engage with the limiting block provided on the fixing seat to achieve a bidirectional limiting function. In addition, since the side of the reed relative to the positioning ring is provided with a positioning projection and the positioning groove provided on the outer edge of the positioning ring engages with each other, the positioning function can be achieved.
