The opening direction of the second arc groove 201 is the same as the extension direction of the outer sleeve 210, and the second arc groove 201 surrounds the outer sleeve 210. a part of. The second arc slot 201 is arranged opposite to the first arc slot 101, and the arc centers of the first arc slot 101 and the second arc slot 201 are located on the relative pivot axis of the first rotating base 100 and the second rotating base 200. The extension arc of the second arc groove 201 is set according to the total arc of the relative pivot stroke predetermined by the first rotating seat 100 and the second rotating seat 200. The sum of the extension arc of the first arc slot 101 and the extension arc of the second arc slot 201 is the total arc of the relative pivot stroke predetermined by the first rotating seat 100 and the second rotating seat 200.

於本實施例中，軸管110的外壁面形成有一外螺牙111以及平行於軸管110的中心軸延伸的一縱槽112，而且縱槽112較佳地延伸橫斷外螺牙111。外套筒210的內壁面凸設有一內凸緣211，軸管110的外螺牙111螺接有一螺母220，螺母220止擋內凸緣211以避免軸管110與外套筒210滑脫，藉此將軸管110與外套筒210相互固定。 In this embodiment, the outer wall surface of the shaft tube 110 is formed with an outer thread 111 and a longitudinal groove 112 extending parallel to the central axis of the shaft tube 110, and the longitudinal groove 112 preferably extends across the outer thread 111. The inner wall surface of the outer sleeve 210 is convexly provided with an inner flange 211, the outer thread 111 of the shaft tube 110 is screwed with a nut 220, and the nut 220 stops the inner flange 211 to prevent the shaft tube 110 from slipping off the outer sleeve 210. Thereby, the shaft tube 110 and the outer sleeve 210 are fixed to each other.

軸管110套設有一固定環240，固定環240被夾持在軸管110的外壁面及外套筒210的內壁面之間，藉此支撐在軸管110及外套筒210之間使得軸管110及外套筒210能夠穩定地相對樞轉。固定環240的外側壁凸設有一外凸緣241，外凸緣241介於螺母220與套筒的內凸緣211之間，因此其也可以用於止擋外套筒210的內凸緣211。 The shaft tube 110 is sleeved with a fixing ring 240. The fixing ring 240 is clamped between the outer wall surface of the shaft tube 110 and the inner wall surface of the outer sleeve 210, thereby being supported between the shaft tube 110 and the outer sleeve 210 so that the shaft The tube 110 and the outer sleeve 210 can pivot relatively stably. An outer flange 241 is protruded from the outer side wall of the fixing ring 240. The outer flange 241 is interposed between the nut 220 and the inner flange 211 of the sleeve. Therefore, it can also be used to stop the inner flange 211 of the outer sleeve 210. .

軸管110套設有一止滑環230，止滑環230較佳地位於螺母220反於軸管110的一側且接觸螺母220。止滑環230的內緣凸設有一凸榫231且凸榫231卡接縱槽112而使止滑環230無法旋轉，螺母220迫緊止滑環230。由於止滑環230無法旋轉，當軸管110及外套筒210相對樞轉時，螺母220不會被軸管110及外套筒210牽動旋轉而鬆脫。 The shaft tube 110 is sleeved with a slip ring 230, and the slip ring 230 is preferably located on the side of the nut 220 opposite to the shaft tube 110 and contacts the nut 220. The inner edge of the anti-slip ring 230 is convexly provided with a tenon 231 and the tenon 231 is engaged with the longitudinal groove 112 so that the anti-slip ring 230 cannot rotate, and the nut 220 tightens the anti-slip ring 230. Since the anti-slip ring 230 cannot rotate, when the shaft tube 110 and the outer sleeve 210 are relatively pivoted, the nut 220 will not be rotated by the shaft tube 110 and the outer sleeve 210 to loosen.

第二旋轉座200對應該螺母220開設有一通口202，且該通口202以一門蓋203封閉。螺母220的外緣形成有至少一缺緣221，使用者可以移除門蓋203並通過通口202將工具卡入螺母220的缺緣221以鎖固螺母220。 The second rotating seat 200 defines a through opening 202 corresponding to the nut 220, and the through opening 202 is closed by a door cover 203. At least one notch 221 is formed on the outer edge of the nut 220, and the user can remove the door cover 203 and clamp a tool into the notch 221 of the nut 220 through the through opening 202 to lock the nut 220.

限位滾子300夾設在該第一旋轉座100及該第二旋轉座200之間，限位滾子300的一半部容置在第一弧槽101內且限位滾子300的另一半部容置在該第二弧槽201內。第一弧槽101及第二弧槽201的至少其中之一套設有一襯墊120，襯墊120較佳地為塑膠製因此較第一弧槽101或第二弧槽201的內壁面質軟。襯墊120的外形與第一弧槽101或第二弧槽201相配合，襯墊120凸設有一定位卡榫121，定位卡榫121嵌入第一旋轉座100而固定襯墊120，且限位滾子300抵接於襯墊120以避免磨損第一弧槽101或第二弧槽201，於本實施例中，第一弧槽101設置有襯墊120當限位滾子300滾動時，其受力先磨損較軟的襯墊120，因此能夠延長旋轉軸結構的使用壽命。具體而言，襯墊形成有對應第一弧槽101內壁形狀的槽部122，槽部122在襯墊120的其中一面呈凹陷狀而在襯墊120的另一面凸出，槽部122的凸出面貼合第一弧槽101的內壁，限位滾子300抵接於槽部122的凹面。 The limiting roller 300 is sandwiched between the first rotating seat 100 and the second rotating seat 200, one half of the limiting roller 300 is accommodated in the first arc groove 101 and the other half of the limiting roller 300 is received The part is accommodated in the second arc groove 201. At least one of the first arc groove 101 and the second arc groove 201 is provided with a gasket 120. The gasket 120 is preferably made of plastic and is therefore softer than the inner wall surface of the first arc groove 101 or the second arc groove 201 . The shape of the liner 120 is matched with the first arc groove 101 or the second arc groove 201. The liner 120 is protrudingly provided with a positioning tenon 121. The positioning tenon 121 is embedded in the first rotating seat 100 to fix the liner 120 and limit the position. The roller 300 abuts against the gasket 120 to avoid wearing the first arc groove 101 or the second arc groove 201. In this embodiment, the first arc groove 101 is provided with a gasket 120. When the limit roller 300 rolls, it The soft liner 120 is first worn out by force, so the service life of the rotating shaft structure can be prolonged. Specifically, the gasket is formed with a groove 122 corresponding to the shape of the inner wall of the first arc groove 101. The groove 122 is concave on one surface of the gasket 120 and protrudes on the other surface of the gasket 120. The convex surface is attached to the inner wall of the first arc groove 101, and the limiting roller 300 abuts against the concave surface of the groove 122.

參閱圖6至圖8，本發明的旋轉軸結構，其藉由第一弧槽101、第二弧槽201及限位滾子300限定第一旋轉座100與第二旋轉座200相對旋轉的雙向終點。具體而言，當第一弧槽101與第二弧槽201沿一方向相對旋轉的過程中，第一弧槽101與第二弧槽201逐漸分離使得第一弧槽101與第二弧槽201之間重合可供容置限位滾子300的空間逐漸縮小。當第一弧槽101與第二弧槽201繼續相對旋轉，直到前述重合的空間縮小至僅剩第一弧槽101的其中一端點與第二弧槽201的其中一端點重合時，限位滾子300阻擋在前述的兩個端點之間使得前述的 兩個端點無法相互脫離。藉此使得第一弧槽101與第二弧槽201無法繼續相對旋轉，因此限定了此方向樞轉行程的終點。第一弧槽101與第二弧槽201沿另一相反方向相對旋轉時，限位滾子300由相同的方式限定了反向樞轉行程的終點。於本實施例中，第一弧槽101及第二弧槽201分別延伸180度，因此第一旋轉座100與第二旋轉座200可相對樞轉行程為第一弧槽101延伸弧度及第二弧槽201延伸弧度的總和，即360度。 Referring to FIGS. 6 to 8, the rotating shaft structure of the present invention uses the first arc groove 101, the second arc groove 201 and the limiting roller 300 to limit the relative rotation of the first rotating seat 100 and the second rotating seat 200 in both directions end. Specifically, when the first arc groove 101 and the second arc groove 201 are relatively rotated in one direction, the first arc groove 101 and the second arc groove 201 are gradually separated so that the first arc groove 101 and the second arc groove 201 are gradually separated. The space for accommodating the limit roller 300 is gradually reduced. When the first arc groove 101 and the second arc groove 201 continue to rotate relative to each other until the overlapped space is reduced to only one of the end points of the first arc groove 101 and one of the end points of the second arc groove 201 overlap, the limit roll The sub 300 is blocked between the aforementioned two end points so that the aforementioned The two endpoints cannot be separated from each other. As a result, the first arc slot 101 and the second arc slot 201 cannot continue to rotate relative to each other, thus limiting the end point of the pivoting stroke in this direction. When the first arc groove 101 and the second arc groove 201 rotate in another opposite direction, the limit roller 300 defines the end of the reverse pivot stroke in the same manner. In this embodiment, the first arc groove 101 and the second arc groove 201 respectively extend 180 degrees, so the first rotating base 100 and the second rotating base 200 can pivot relative to the first arc groove 101 extending arc and the second arc The arc groove 201 extends the sum of arc degrees, that is, 360 degrees.

綜上所述，本發明的旋轉其第一弧槽101、第二弧槽201及限位滾子300的結構強度遠優於傳統的止擋件，因此相較於傳統的止擋件較不易破損，限位滾子300的滾動也不會影響第一旋轉座100與第二旋轉座200的相對旋轉動作。 In summary, the structural strength of the first arc groove 101, the second arc groove 201 and the limit roller 300 of the present invention is much better than that of the traditional stopper, so it is not easy to rotate compared to the traditional stopper. Damaged, the rolling of the limit roller 300 will not affect the relative rotation of the first rotating seat 100 and the second rotating seat 200.

以上所述僅為本發明之較佳實施例，非用以限定本發明之專利範圍，其他運用本發明之專利精神之等效變化，均應俱屬本發明之專利範圍。 The foregoing descriptions are only preferred embodiments of the present invention, and are not intended to limit the patent scope of the present invention.
