Rotatable mobile phone shell
View Patent ↗A rotatable mobile phone shell is provided. The rotatable mobile phone shell includes a shell body, a rotating component, a finger gripping component and a spring component. The invention has the effect of safely and conveniently using mobile phone while protecting mobile phone.
1. A rotatable mobile phone shell, comprising:
a shell body having front-opening hollow structure and formed with a coupling through hole on back surface;
a rotating component comprising a rotating ring component, a hinge coupling concave portion, and a spring insertion portion, wherein, a peripheral surface of the rotating ring component is capable of rotating with respect to an inner circumferential surface of the coupling through hole, the hinge coupling concave portion is arranged on an inner circumferential surface of the rotating ring component, and the spring insertion portion is formed on the inner circumferential surface of the rotating ring component and communicated to two end portions of the hinge coupling concave portion;
a finger gripping component comprising a finger gripping ring, a hinge end, and a spring insertion groove, wherein the hinge end is integrated on a peripheral surface of the finger gripping ring and arranged at the hinge coupling concave portion, the spring insertion groove is formed at the hinge end and one side surface of the finger gripping ring, and configured to communicate one end of the hinge end to the other end of the hinge end through the one side surface of the finger gripping ring; and
a spring component inserted into the spring insertion groove and having two end portions forcibly pressed into the spring insertion portion;
wherein the inner circumferential surface of the coupling through hole consists of a first two-end circumferential surface portion and a first central circumferential surface portion located at inner side of the first two-end circumferential surface portion; and the first two-end circumferential surface portion is rounded and chamfered, the first central circumferential surface portion is formed to be 0.1-1 mm larger than an inner diameter of the coupling through hole, and a plurality of blocking protrusions spaced at a predetermined distance are formed on the first central circumferential surface portion;
wherein the peripheral surface of the rotating ring component consists of a second two-end circumferential surface portion and a second central circumferential surface portion located at inner side of the second two-end circumferential surface portion; and the second two-end circumferential surface portion is rounded and chamfered, the second central circumferential surface portion is formed with a convex portion having semi-arc section in radius direction, and a plurality of blocking grooves spaced at the predetermined distance are formed on the second central circumferential surface portion for insertion or detachment of the blocking protrusions.
2. The rotatable mobile phone shell of claim 1 , wherein the finger gripping component further comprises:
a pull-out end portion formed as a concave portion or a convex portion at an opposite position of the hinge end on the inner circumferential surface of the finger gripping ring, and
a cover protrusion provided on the peripheral surface of the finger gripping ring.
