实施例一
如图1所示，本发明实施例提供的旋转调节机构，包括：第一锁止件100、第二锁止件200、旋转盘300和底座400；旋转盘300转动连接于底座400；第一锁止件100和第二锁止件200均具有锁止状态和解锁状态，在锁止状态下旋转盘300被锁固于底座400，在解锁状态下旋转盘300被解锁；第一锁止件100与第二锁止件200联动，以在锁止状态和解锁状态之间同步切换。
具体地，在锁止状态下，第一锁止件100和第二锁止件200共同作用，以将旋转盘300锁止，可以提高旋转盘300被锁止时的稳定性。第一锁止件100与第二锁止件200联动，以便通过同步操控实现锁止或解锁。
在本发明实施例中，第一锁止件100与第二锁止件200间隔设置，第一锁止件100和第二锁止件200分别活动连接于旋转盘300。
一些实施例中，旋转盘300和底座400中的其一连接第一锁止件100和第二锁止件200，且第一锁止件100和第二锁止件200均包括锁销，销轴滑动插设于旋转盘300和底座400中的其一，旋转盘300和底座400中的另一设有与锁销相适配的销孔，销孔与旋转盘300的旋转轴线间隔设置。第一锁止件100连接第二锁止件200，自锁止状态至解锁状态，两个销轴同时从销孔中拔出，从而使旋转盘300能够自由转动；自解锁状态至锁止状态，两个销轴一一对应地插设于两个销孔中，从而将旋转盘300锁止。
本实施例中，第一锁止件100和第二锁止件200分别枢转连接于旋转盘300，底座400设有分别与第一锁止件100和第二锁止件200相适配的锁固部，锁固部可采用卡槽或凸块等，当第一锁止件100和第二锁止件200分别配合于锁固部时，旋转盘300被锁止；当 第一锁止件100和第二锁止件200分别摆转至脱离锁固部时，旋转盘300可自由转动。
进一步的，第一锁止件100包括第一锁钩，第二锁止件200包括第二锁钩，第一锁钩和第二锁钩分别枢接于旋转盘300；底座400上连接有第一锁固件401和第二锁固件402，第一锁固件401与第二锁固件402间隔设置；第一锁钩和第二锁钩分别择一适配于第一锁固件401和第二锁固件402。
具体的，第一锁固件401和第二锁固件402均包括连接在底座400上的杆件；相对于旋转盘300的旋转轴线，第一锁固件401和第二锁固件402所对应的圆心角为180度。自第一锁钩配合第一锁固件401，且第二锁钩配合第二锁固件402的状态，切换至第一锁钩配合第二锁固件402，且第二锁钩配合第一锁固件401的状态。即：旋转盘300每旋转180度，可自一个锁止工位到达另一锁止工位，以便第一锁止件100和第二锁止件200均自解锁状态切换至锁止状态。
一些实施方式中，第一锁固件401和第二锁固件402均设有多个，绕旋转盘300的旋转轴线，第一锁固件401和第二锁固件402逐一间隔设置。当旋转盘300绕旋转轴线旋转时，通过第一锁钩配合于第一锁固件401和第二锁固件402中的其一，第二锁钩配合于 第一锁固件401和第二锁固件402中的另一，从而可实现对旋转盘300锁止。
如图1、图4和图5所示，第一锁钩和第二锁钩的开口朝向相反；在锁止状态下，第一锁钩配合在第一锁固件401朝向第二锁固件402的一侧，第二锁钩配合在第二锁固件402朝向第一锁固件401的一侧；自锁止状态至解锁状态，第一锁钩和第二锁钩分别向内侧摆转。
在锁止状态下，第一锁钩和第二锁钩一一对应地抵接在第一锁固件401和第二锁固件402的内侧，从而使第一锁钩和第二锁钩分别与底座400稳固配合，以提高锁止状态下旋转盘300的稳定性。自锁止状态至解锁状态，第一锁钩和第二锁钩分别向内侧摆转，可以缩小解锁状态下第一锁钩和第二锁钩在旋转盘300径向上所占的空间，相比于第一锁钩和第二锁钩向外侧摆转实现解锁，可以减小布置第一锁钩和第二锁钩所需的尺寸空间，进而使旋转调节机构结构更紧凑。
如图1、图4、图5和图6所示，旋转盘300上活动连接有释锁件500；释锁件500具有第一工位和第二工位；在释锁件500处于第一工位的状态下，第一锁止件100和第二锁止件200均处于锁止状态；在第二工位，第一锁止件100和第二锁止件200均处于解锁状 态。
一些实施例中，第一锁止件100和第二锁止件200均采用锁销，释锁件500连接第一锁止件100和第二锁止件200，通过操作释锁件500可同时插拔两个锁销，从而实现同步解锁或锁止。
本实施例中，第一锁止件100包括第一锁钩，第二锁止件200包括第二锁钩，第一锁钩和第二锁钩分别与释锁件500联动，通过释锁件500可同时驱动第一锁钩和第二锁钩摆转，进而实现同步解锁或锁止。
如图1、图2、图3、图4和图5所示，第一锁钩设有第一槽孔110，第二锁钩设有第二槽孔210；释锁件500设有第一释锁部501和第二释锁部502，第一释锁部501插设于第一槽孔110，第二释锁部502插设于第二槽孔210；释锁件500在第一工位和第二工位之间移动，并使第一释锁部501沿第一槽孔110滑动，以及第二释锁部502沿第二槽孔210滑动。
具体的，释锁件500滑动连接于旋转盘300，且释锁件500的滑动方向与旋转盘300的旋转轴线具有夹角，该夹角可配置为60度、70度、90度或100度。当释锁件500在第一工位和第二工位之间移动时，第一释锁部501沿第一槽孔110滑动，第二释锁部502沿第 二槽孔210滑动，通过第一释锁部501驱动第一锁止件100摆转，并通过第二释锁部502驱动第二锁止件200摆转。
一种实施方式中，第一锁钩设有第一轴孔，连接旋转盘300的第一铰接轴插设于第一轴孔，以将第一锁钩枢转连接在旋转盘300上。第二锁钩设有第二轴孔，连接旋转盘300的第二铰接轴插设于第二轴孔，以将第二锁钩枢转连接在旋转盘300上。第一轴孔位于第一槽孔110和第一锁钩的沟槽之间，第二槽孔210位于第二轴孔和第二锁钩的沟槽之间，当释锁件500相对于旋转盘300滑动时，第一释锁部501驱动第一锁钩摆转，第二释锁部502驱动第二锁钩摆转，且第一锁钩的摆转方向与第二锁钩的摆转方向相反。
进一步的，第一槽孔110包括：第一限位部111和连通第一限位部111的第一滑槽部112；第二槽孔210包括：第二限位部211和连通第二限位部211的第二滑槽部212；在释锁件500处于第一工位的状态下，第一释锁部501配合于第一限位部111，第二释锁部502配合于第二限位部211；在释锁件500处于第二工位的状态下，第一释锁部501配合于第一滑槽部112，第二释锁部502配合于第二滑槽部212。
一些实施例中，第一限位部111和第一滑槽部112的延伸方向相 同，且第一限位部111的宽度尺寸小于第一滑槽部112的宽度尺寸。第一释锁部501沿第一滑槽部112滑动时，第一滑槽部112起导向作用，且应避免第一滑槽部112的宽度尺寸较小导致第一释锁部501卡滞。在锁止状态下，释锁件500处于第二工位，第一释锁部501滑动至第一限位部111，第一限位部111可夹持第一释锁部501，从而确保第一释锁部501无松动，进而提高锁止状态下旋转调节机构的稳定性。同理，第二限位部211和第二滑槽部212的延伸方向相同，且第二限位部211的宽度尺寸小于第二滑槽部212的宽度尺寸。第二释锁部502沿第二滑槽部212滑动时，第二滑槽部212起导向作用，且应避免第二滑槽部212的宽度尺寸较小导致第二释锁部502卡滞。当释锁件500处于第二工位，第二释锁部502滑动至第二限位部211，第二限位部211可夹持第二释锁部502，从而确保第二释锁部502无松动，以提高锁止状态下旋转调节机构的稳定性。
本实施例中，第一限位部111的延伸方向与第一滑槽部112的延伸方向具有夹角，第二限位部211的延伸方向与第二滑槽部212的延伸方向具有夹角。其中，第一限位部111的延伸方向与第一滑槽部112的延伸方向的夹角可配置为90度，第二限位部211的延伸方向与第二滑槽部212的延伸方向的夹角可配置为90度。
具体的，当释锁件500相对于旋转盘300滑动时，第一释锁部 501沿第一滑槽部112滑动，且第二释锁部502沿第二滑槽部212滑动。在锁止状态下，第一释锁部501配合于第一限位部111，第二释锁部502配合于第二限位部211，通过第一限位部111可避免第一释锁部501松动并进入第一滑槽部112，通过第二限位部211可避免第二释锁部502松动并进入第二滑槽部212，从而提高了锁止状态下旋转调节机构的稳定性。需要说明的是，自第二工位至第一工位，释锁件500向第一方向滑动。自连通第一滑槽部112的一端至背离第一滑槽部112的一端，第一限位部111沿第一方向延伸；自连通第二滑槽部212的一端至背离第二滑槽部212的一端，第二限位部211沿第一方向延伸。在释锁件500自第一工位滑动至第二工位过程中，释锁件500沿与第一方向相反的方向滑动，从而使第一释锁部501能够从第一限位部111滑动至第一滑槽部112，并使第二释锁部502能够从第二限位部211滑动至第二滑槽部212，可以避免第一释锁部501和第二释锁部502在解锁过程中产生卡滞。
如图1、图4、图5和图6所示，释锁件500与底座400之间设有弹性元件600，弹性元件600配置为使释锁件500具有自第二工位移动至第一工位的趋势。其中，弹性元件600包括弹簧，弹性元件600的一端连接释锁件500，弹性元件600的另一端连接底座400。手动操作可将释锁件500自第一工位移动至第二工位，释放释锁件 500时，释锁件500在弹性元件600的作用下自第二工位移动至第一工位。释锁件500和旋转盘300其一设有滑槽，另一设有与滑槽适配的滑块。当释锁件500在第一工位和第二工位之间移动时，滑块沿滑槽滑动，从而避免释锁件500产生偏斜或松动。
本实施例中，弹性元件600采用拉簧，拉簧的一端连接释锁件500，拉簧的另一端连接底座400，当释锁件500自第一工位移动至第二工位时，拉簧产生弹性变形并伸长，从而使释锁件500具有自第二工位移动至第一工位的趋势。
实施例二
如图1所示，本发明实施例提供的座椅，包括：座椅本体和实施例一提供的旋转调节机构，座椅本体安装于旋转盘300。当第一锁止件100和第二锁止件200均处于解锁状态时，座椅本体与旋转盘300可以同步旋转，从而调节座椅本体的朝向；第一锁止件100和第二锁止件200均处于锁止状态时，旋转盘300被锁止，从而可以将座椅本体的朝向固定。本实施例提供的座椅具有与旋转调节机构相同的技术效果，故在此不再赘述。
最后应说明的是：以上各实施例仅用以说明本发明的技术方案，而非对其限制；尽管参照前述各实施例对本发明进行了详细的说明， 本领域的普通技术人员应当理解：其依然可以对前述各实施例所记载的技术方案进行修改，或者对其中部分或者全部技术特征进行等同替换；而这些修改或者替换，并不使相应技术方案的本质脱离本发明各实施例技术方案的范围。
