Smart mobile phone shell
View Patent ↗The invention relates to a smart mobile phone shell. The smart mobile phone shell includes a shell body, a fixing component, a rotating component and a support ring. The invention has the effects of easy disassembly and safe use while safely protecting mobile phone.
1. A smart mobile phone shell, comprising:
a shell body having front-opening hollow structure and formed with a coupling through hole on back surface;
a fixing component comprising a ring-shaped fixing component body and a coupling concave portion, wherein the fixing component body is inserted into the coupling through hole, and the coupling concave portion is formed on the inner circumferential surface of the fixing component body;
a rotating component comprising a ring-shaped rotating component body, multiple coupling convex portions, a support ring coupling concave portion and a spring insertion portion, wherein the coupling convex portions are formed on the outer circumferential surface of the rotating component body and rotationally coupled with the coupling concave portion, the support ring coupling concave portion is formed at one side of the inner circumferential surface of the rotating component body, and the spring insertion portion is formed on the inner circumferential surface of the rotating component body and communicated to the two end portions of the support ring coupling concave portion; and
a support ring comprising a ring-shaped support ring body and a pull-out end portion, wherein one end portion of the outer circumferential surface of the support ring body is rotationally inserted into the support ring coupling concave portion, a spring insertion groove is formed on the outer circumferential surface, and the pull-out end portion is formed at the other end portion of the outer circumferential surface of the support ring body,
wherein the coupling convex portion comprises a convex body and coupling convexes, and the coupling convexes are separated by distance from the outer circumferential surface of the rotating component body and formed on two ends of the convex body; and the coupling convexes have symmetric shape with a phantom line connecting from the center of the rotating component body to the convex body as reference.
2. A smart mobile phone shell, comprising:
a shell body having front-opening hollow structure and formed with a coupling through hole on back surface;
a fixing component comprising a ring-shaped fixing component body and a coupling concave portion, wherein the fixing component body is inserted into the coupling through hole, and the coupling concave portion is formed on the inner circumferential surface of the fixing component body;
a rotating component comprising a ring-shaped rotating component body, multiple coupling convex portions, a support ring coupling concave portion and a spring insertion portion, wherein the coupling convex portions are formed on the outer circumferential surface of the rotating component body and rotationally coupled with the coupling concave portion, the support ring coupling concave portion is formed at one side of the inner circumferential surface of the rotating component body, and the spring insertion portion is formed on the inner circumferential surface of the rotating component body and communicated to the two end portions of the support ring coupling concave portion; and
a support ring comprising a ring-shaped support ring body and a pull-out end portion, wherein one end portion of the outer circumferential surface of the support ring body is rotationally inserted into the support ring coupling concave portion, a spring insertion groove is formed on the outer circumferential surface, and the pull-out end portion is formed at the other end portion of the outer circumferential surface of the support ring body,
wherein the coupling through hole is formed with a step surface on the inner circumferential surface of the back surface, and the fixing component body is formed with multiple spaced coupling long grooves in front surface; and the smart mobile phone shell also comprises a cover, wherein the cover comprises a cover body and multiple coupling convex pieces, the cover body is inserted into the step surface, and the multiple coupling convex pieces are formed at one side surface edge of the cover body and inserted in the coupling long grooves.
