New Description: [New Technical Field] This creation is about the rotation of a hinge between the cover and the body of a small clamshell electronic device to enable the carcass to open and close and rotate relative to the body. Improvement of the positioning mechanism. [Prior Art] Electronic devices currently sold on the market or frequently used by users, such as mobile phones, digital cameras, etc., have a hinge between the cover body and the body, so that the cover can be opposite After the body is opened or closed, 0, and with the evolution of the manufacturing technology of the hub and the increase of the user's demand, there is a sigh that can further rotate the cover relative to the body in addition to opening and closing the cover relative to the body. To assist the user in the convenient use of the electronic device at any angle, such as the new "framework" patent case, which includes a two-fixing frame and a rotating frame fixed to the cover body, and The purpose of the second frame opening 35 and the opening and closing shaft group 'to enable the cover body to open and close or rotate relative to the body. In order to maintain the normal operation and rotation of the electronic device, the hoisting operation 'the hub benefits from the fixed frame on the fixed cap body (4) in the body positioning structure, that is, its protruding - spin = protruding Γ fixed sleeve ' The center of the rotating frame is respectively formed with a contact surface of the R 111 疋 sleeve and the circumference of the rotating sleeve to reach the positioning 2 positioning tooth portion, and the mutual catering between the positioning tooth portions is J 曰. M322719 After the long-term use of the hinge, the engaging surface between the two positioning teeth will wear gradually, which not only reduces the positioning effect, but also causes the cover body to shake relative to the body, resulting in inconvenience in use. The technology hub has its potential for further improvement. [New content] In view of the above-mentioned deficiencies of the prior art, the present invention improves the structure for the rotational positioning in the hinge, so that the positioning effect is reduced even after a long period of use, and the fixed frame and the rotating bearing are not affected. The connection between the shelves is touching. In order to achieve the above-mentioned creative purpose, the improvement of the rotary positioning mechanism of the creative hinge comprises: a fixed bracket formed into a tube body, in which an opening and closing shaft set is mounted, and a fixed bearing is arranged on the outer side surface The axially vertical sleeve, the square slewing and casting, has a shaft hole formed therein, and the sleeve on the fixed bracket is sleeved by the shaft hole, and the rotating bracket is not opposite to the fixed bracket. (4) Around the hole, a plurality of positioning concave portions are formed along the radial direction thereof, and a limiting block is disposed between the two positioning concave portions; a rotating shaft group is sleeved with the sleeve of the fixed bearing frame, and is formed by rotating the two frames On the side of the positioning recess, the rotating shaft set includes an inner positioning ring adjacent to the rotating bracket, and the relative position between the sleeve and the fixed bracket is fixed, and the inner positioning ring is formed on the side surface thereof. The positioning protrusion which can be engaged with the positioning concave portion of the rotating frame has a limiting piece protruding from the periphery thereof. The advantage of this creation is that it adopts the positioning concave portion on the rotating frame and (s 6 M322719 limit block cooperates with the positioning convex portion and the limiting piece on the inner positioning ring to achieve the rotation positioning between the two frames, so even After a long time of use, the locking surface of the positioning concave and convex portions is gradually worn, thereby reducing the positioning effect thereof and not affecting the contact surface between the two carriers, so as to avoid the cover of the electronic device from being opposite to the cover. The purpose of the body is shaken. [Embodiment] Referring to the first and second figures, the rotation positioning mechanism of the creative hinge device comprises a fixed frame (10), a rotating frame (2 turns) and a rotating shaft. Group (30), wherein: further referring to the seventh figure, the fixed frame (1〇) is installed in the body (41) of the electronic device (40), which is formed into a tube body and includes a opening and closing A shaft assembly (11), a sleeve (12) and a separation ring (13), the opening and closing shaft assembly (11) is pivoted in the fixed bracket (10) and is connected to the body of the electronic device (4〇) The mutual fixing 'sleeve (12) has a non-circular cross section, which protrudes and is fixed to The outer side surface of the carrier (10) is perpendicular to the axial direction of the fixed bracket (10), and the central locking sleeve (13) is formed in the shape of the central fitting sleeve (12) through a non-circular hole, and the separating ring (13) The sleeve (12) is sleeved so that one end thereof abuts against the outer side surface of the fixed frame (1〇); the rotating frame (20) is fixed in the cover body (42) of the electronic device (40)' A shaft hole (21) is formed in the center thereof, and the shaft hole (21) is used to sleeve the rotating bracket (20) against the sleeve (12) and abut against the other side of the partition ring (13), so that the rotating bracket (20) Rotating relative to the fixed frame (1〇), on the other side of the rotating frame (2〇) that does not abut the separation ring (13), along the controllable direction around the shaft hole (21) There are a plurality of positioning recesses (22), wherein a limiting block (23) is disposed between the two positioning recesses (22) M322719, and the opening and closing shaft (11) is fixed in the fixed bracket (1〇), so that The body (42) fixed to the rotating frame (2〇) on the electronic device (40) can be opened or closed with respect to the body (41); the rotating shaft set (30) includes an inner positioning ring (31), an elastic Component (3 2) and an outer positioning ring (33); further see the third and fourth figures, the inner positioning ring (31) is centrally formed and formed with a perforation (31〇) which is formed in accordance with the shape of the sleeve (12). a non-circular hole, a plurality of positioning protrusions (311) are formed on one side of the inner positioning ring (31), and a limiting piece (312) is protruded from the outer periphery, and the through hole (310) is sleeved The sleeve (12) prevents the inner positioning ring (31) from rotating relative to the sleeve (12) and positions the positioning protrusion (311) of the inner positioning ring (31) and the positioning recess of the rotating carrier (2〇) ( 22) can be engaged with each other, and further refer to the fifth and sixth figures, so that when the rotating frame (2〇) is rotated relative to the fixed frame (1〇), the positioning concave and convex portions can be used (22, 311). And achieving the effect of mutual positioning, and the one side of the limiting piece (312) abuts against the limiting block (23) to limit the range of rotation of the rotating bracket (20) on the sleeve (12); The elastic member (32) is sleeved (12) on the other side of the inner positioning ring (3丨), which may be a spring or a plurality of elastic cymbals; the outer positioning ring (33) is fixed to the sleeve The other end 12 side) and the elastic element (32), so that said sleeve is provided between each of the sleeve elements (12) abut against each other tightly. Because the hinge is matched with the positioning protrusion (311) and the limiting piece (312) on the inner positioning ring (31) by the positioning concave portion (22) on the rotating bracket (20) and the limiting block (23). The effect of positioning the cover body (42) and the body (41), M322719 and the contact surface between the two carriers is a flat plane, so that the positioning concave and convex portions are made even if the hinge is used for a long time. The wear surface of the engaging surface between 311) causes the positioning effect to be clear when it is used at the beginning, and does not affect the contact surface between the two carriers, so that the cover (41) of the electronic device (40) can remain stable. It is placed on its body (42).
