New description: [New technical field] This creation is about a hinge, especially a kind of hinge mounted on a portable electronic device, making the electronic device a foldable hinge. [Prior Art] A folding device generally has two parts that can be relatively rotated. For example, a notebook computer, a base in a mobile phone, and an upper cover can be rotated with each other, so that the upper cover can be opened for operation or folded after use. The upper cover, in order to achieve the above purpose, the frame type device must be provided in the folding device. The prior art tow structure, as disclosed in the new patent publication No. 566771, mainly has a rotating shaft portion, a rotating shaft portion and a pushing top. And a mandrel that is disposed on each of the foregoing parts, wherein the rotating shaft portion and the rotating shaft portion are respectively fixed on two rotatable portions of the folding device, and are connected to each other The surface of the abutting surface is respectively provided with a concave portion corresponding to the rotation, and the elastic member is disposed adjacent to the rotating shaft portion and the rotating shaft portion is pressed against each other; ^ When the folding device is relatively rotatable In the two parts (the above cover and bottom: for example), when the relative rotation is performed, the rotating sleeve portion and the rotating shaft portion can be rotated relative to each other: (4) The concave-convex portion on the interface between the Μ and the turn can be designed to achieve the upper surface. The base is oriented toward the front and back of the two _ degrees ' every 90 degrees or other angles. The design of the drag-and-drop device since then has the purpose of positioning in the forward or reverse direction. However, when the folding device is used, the upper cover is located at an angle for operation, and the use of the door is expected to close the upper 3 M376117 cover as soon as possible, whereas the prior art hinge has a two-way The positioning function, on the contrary, causes extra time and effort to be used when closing the upper cover, which is very inconvenient for the user. [New content] In view of the use of the above-mentioned prior art hinge device, the presence of the closure device is closed. The time required for the cover is time-consuming and labor-intensive. In order to solve the above shortcomings, the original technique is used to improve the structure of the button, so that the above-mentioned shortcomings can be solved in a single rotation direction. The method is to provide a ratchet type hub, comprising: a rotating shaft; a rotating ratchet having a ratchet on one axial side thereof and being rotatable The sleeve is arranged on the rotating shaft; the fixed ratchet has a ratchet tooth formed on the axial side thereof, and the fixed ratchet wheel is non-rotatably sleeved on the rotating shaft, and the ratchet teeth and the ratchet teeth of the rotating ratchet are mutually reciprocated; The sleeve is sleeved on the rotating shaft, and the end is opposite to the other axial side of the fixed ratchet; the cymbal sleeve is provided with a set of joints and axially formed with an open sleeve sleeved on the rotating ratchet On the other side of the cyanine. 'It is fixed at one end of the sleeve and is in contact with the assembly of the hinge and the sleeve of the hinge and the sleeve. Relatively rotating to open or fold the skin Μ 相互 相互 相互 J J J J ^ ^ 疋 由于 由于 由于 由于 由于 由于 由于 由于 由于 由于 由于 由于 由于 由于 由于 由于 由于 由于 由于 由于 由于 由于 由于 由于 由于 由于 由于 由于 由于 由于 由于 由于 由于 由于 由于 由于 由于 由于 由于 由于The teeth remain in meshing with each other 'the rotating ratchet can only rotate one-way with respect to the fixed ratchet; when the sleeve rotates in the direction in which the rotating ratchet can rotate relative to the fixed ratchet, the rotating ratchet can be rotated relative to the fixed ratchet, and the spine is rotated by the spine The cooperation of the teeth in the direction of rotation achieves the purpose of multi-segment positioning Conversely, when the sleeve rotates in the opposite direction, the rotating ratchet will be subject to the fixed ratchet: without rotating the kernel, since the slit is formed on the sleeve, the inner diameter of the sleeve will be slightly enlarged due to the force, so that the sleeve It can be rotated relative to the rotating ratchet; thus, it can be seen that the folding device provided with the creative hinge can have a multi-segment function when turned on, and can be quickly closed after use. [Embodiment] Referring to the first and second figures, the ratcheting hub of the present invention comprises a rotating shaft (10), a rotating ratchet (20), a fixed ratchet (3 〇), and a compression spring (40). a sleeve (5〇) and a fixing plate (6〇), wherein: the shaft (11) is formed with a crown portion (11), and one end is formed with a non-circular cross section (I2). As shown in the third figure, the rotating ratchet (20) is formed with a central hole (2 1 ) in the axial direction, and a ratchet (22) is formed on one side of the axial direction, and the rotating ratchet (20) is used to The central hole (21) is rotatably sleeved on the rotating shaft (1〇) and abuts against the crown (11). The fixed ratchet (30) is formed with a shaft hole (31) that fits the engaging portion (12) of the rotating shaft (12) in the axial direction, and a ratchet (32) is formed on one side of the axial direction, and A groove (33) is formed on the other side of the axial direction, and the fixed ratchet wheel (3〇) is sleeved on the engaging portion (12) of the rotating shaft (1〇) by the non-rotatable rotation of the shaft hole (31), and the ratchet teeth thereof (32) and intermeshing with the ratchet (22) of the rotating ratchet (2〇), the outer diameter of the fixed ratchet (30) 5 M376117 may be smaller than the rotating ratchet (20); the compression spring (40) is sleeved on One end of the rotating shaft (10) abuts against the inner wall of the groove (33) of the fixed ratchet wheel (30); the inner diameter of the sleeve (50) is matched with the outer diameter of the rotating ratchet wheel (20), the sleeve (50) a plurality of joints (51) are provided, and a slit (52) is formed in the axial direction, the slit (52) is adjacent to the joint portion (5 1 ), and is located at the joint portion ( 5 1) a base point in a direction in which the rotating ratchet (20) is relatively fixed in a direction in which the ratchet wheel (30) is fixed, and a sleeve (50) is sleeved on the rotating ratchet (20); the fixing plate (60) Fixed to one end of the shaft (10) The other end of the elastic compression basketful (40), so that the compression spring (40) generating the spring force pushing against the fixed ratchet (30) holding the rotation intermesh with ratchet (20). As shown in the fourth and fifth figures, the hinge of the present invention is provided on a folding device. Here, a digital photo frame is taken as an example, which has a body (71) and an expandable body (71) or a folding stand (72), the body (71) and the rotating shaft (10) are fixed to each other in any suitable manner, and the stand (72) is assembled with the sleeve (50) at any appropriate position. The manners are fixed to each other, and the unfolding direction of the tripod (72) is the same as the direction in which the rotating ratchet (20) can rotate relative to the fixed ratchet (30); when the stand (72) rotates from the folded state toward the unfolding direction, due to the sleeve The inner diameter of (50) is matched to the outer diameter of the rotating ratchet (20), so that the rotating ratchet (20) can be rotated relative to the fixed ratchet (30), and the ratchet (30) is fixed during the rotation of the rotating ratchet (20). Pushing the ratchet (22) against the axial direction of the rotating shaft (10) and pressing the compression spring (40), and then engaging the rotating ratchet (20) by the elastic force of the compression spring (40), by means of The cooperation of the ratchets (22) (32) can achieve the purpose of multi-segment positioning, and the stand (72) is in each segment. The angle of rotation between the bits can be adjusted by the number of ratchets (22) (32). Conversely, when the sleeve (50) is rotated in the opposite direction, since the sleeve is formed with a slit (52), The inner sleeve of the sleeve (9) is slightly enlarged by the force, so that even if the rotating ratchet (10) is subjected to the solid (four) wheel (10), the sleeve 4 (10) can be rotated relative to the rotating ratchet (10) to achieve the folding of the tripod. The purpose of the body (71), and the folding process does not have a function: therefore, the stand (72) can be quickly folded into the body (71).
