Abstract

A carrying clip for an electronic device includes a first clip body, a second clip body, and a spring tab; the first clip body is provided with a snap ring on which a notch is provided; the second clip body is rotatably connected to the first clip body and is provided with a groove, the snap ring of the first clip body is snapped and assembled in the groove of the second clip body and is rotatable along the wall surface of the groove, the wall surface of the groove is uniformly formed with a plurality of snapping slots; the spring tab comprises an annular spring tab body and a protrusion projected on the spring tab body, the spring tab body is snapped and assembled in the snap ring of the first clip body, the protrusion projects out of the notch of the snap ring and abuts against the wall surface of the groove of the second clip body; when the first clip body rotates with respect to the second clip body, the protrusion of the spring tab rotates along the wall surface of the groove alternatively abuts against the snapping slots or non-snapping slots of the wall surface of the groove so as to form stages.

First claim

The invention claimed is:

1. A carrying clip for an electronic device, comprising:
a first clip body provided with a snap ring on which a notch is provided;
a second clip body rotatably connected to the first clip body and provided with a groove, wherein the snap ring of the first clip body is snapped and assembled in the groove of the second clip body and is rotatable along surface of the groove, the wall surface of the groove is uniformly formed with a plurality of snapping slots; and
a spring tab comprising an annular spring tab body and a protrusion projected in the spring tab body, wherein the spring tab body is snapped and assembled in the snap ring of the first clip body, the protrusion projects out of the notch of the snap ring and abuts against the wall surface of the groove of the second clip body; and
the spring tab is made of elastic plastic materials, when the first clip body rotates with respect to the second clip body, the protrusion of the spring tab rotates along the wall surface of the groove to alternatively abut against the snapping slots or non-snapping slots of the wall surface of the groove so as to form stages.

2. The carrying clip for an electronic device according to claim 1 , wherein a material thickness of a part of the spring tab body close to the protrusion becomes thinner uniformly from far to near according to a distance between the spring tab body and the protrusion.

3. The carrying clip for an electronic device according to claim 1 , wherein the spring tab body is an eccentric strap, both an inner wall surface and an outer wall surface of the spring tab body are circular, and a circular center of the inner wall surface deviates from a circular center of the outer wall surface to a direction close to the protrusion, and is located at a connecting line between the circular center of the outer wall surface and a center of the protrusion.

4. The carrying clip for an electronic device according to claim 3 , wherein an eccentricity ratio of the spring tab body is within a range of 2%-10%.

5. The carrying clip for an electronic device according to claim 1 , wherein an outer wall surface of the spring tab body is a circular surface, a half wall surface of an inner wall surface of the spring tab body close to the protrusion is an oval wall surface, a half wall surface keeping away from the protrusion is a circular wall surface, and the oval wall surface of the inner wall surface and the circular wall surface are in smooth transition.

6. The carrying clip for an electronic device according to claim 1 , wherein an inner wall surface and an outer wall surface of the spring tab body are both oval surfaces, a center of the inner wall surface deviates from a center of the outer wall surface to a direction close to the protrusion, and is located at a connecting line between the center of the outer wall surface and a center of the protrusion, a long axis of the outer wall surface is located at the connecting line between the center of the outer wall surface and the center of the protrusion, and a short axis of the outer wall surface is vertical to the connecting line between the center of the outer wall surface and the center of the protrusion.

7. The carrying clip for an electronic device according to claim 1 , wherein an inner wall surface and an outer wall surface of the spring tab body are homocentric circular rings, and a thickness of the spring tab body becomes thinner uniformly from a part keeping away from the protrusion to a part close to the protrusion along a surface width direction of the inner wall surface or the outer wall surface of the spring tab body.

8. The carrying clip for an electronic device according to claim 1 , wherein a limiting structure for limiting a relative rotation of the spring tab body and the snap ring is arranged between , a part of the spring tab body keeping away from the protrusion and the snap ring.

9. The carrying clip for an electronic device according to claim 8 , wherein the limiting structure comprises a limiting groove and a limiting block which are respectively arranged between the spring tab body and the snap ring and matched with each other.

10. The carrying clip for an electronic device according to claim 9 , wherein the limiting block is arranged in the spring tab body and is located at a relative position of the protrusion, the limiting groove is formed in the snap ring and is located at a relative position of the notch, and the limiting groove penetrates through the snap ring, so that the snap ring is separated into two relatively arranged arc sections by the notch and the limiting groove.

11. The carrying clip for an electronic device according to claim 1 , wherein the non-snapping slots of a groove wall surface are multiple sections of homocentric arc surfaces with a same diameter, the wall surfaces of all the snapping slots are arc surfaces with a same size, and an arc center of the non-snapping slot of the groove overlaps with a center of the spring tab body and is located at a center of rotation of the first clip body and the second clip body.

12. The carrying clip for an electronic device according to claim 1 , wherein the first clip body and the second clip body are both made of plastic materials.

13. The carrying clip for an electronic device according to claim 2 , wherein the spring tab body is an eccentric strap, both an inner wall surface and an outer wall surface of the spring tab body are circular, and a circular center of the inner wall surface deviates from a circular center of the outer wall surface to a direction close to the protrusion, and is located at a connecting line between the circular center of the outer wall surface and a center of the protrusion.

14. The carrying clip for an electronic device according to claim 2 , wherein an outer wall surface of the spring tab body is a circular surface, a half wall surface of an inner wall surface of the spring tab body close to the protrusion is an oval wall surface, a half wall surface keeping away from the protrusion is a circular wall surface, and the oval wall surface of the inner wall surface and the circular wall surface are in smooth transition.
