具体实施方式
以下结合附图对本发明作进一步详细说明。
实施例1：一种便于更换床单的床架，如图1所示，包括矩形基座100，基座100一端设有床头板101。基座100上方设有用于放置床垫的旋转模块102，旋转模块102在本实施例中优选为床板，旋转模块102与基座100之间还设有滑动模块103，滑动模 块103在本实施例中优选为滑动板，滑动模块103与基座100之间设有滑移机构200，滑动模块103与旋转模块102之间设有旋转机构300，基座100环绕其边沿设有用于支撑旋转模块102的支撑结构400，滑动模块103与基座100之间设有用于将两者位置关系锁定的锁定机构500。
如图2所示，滑移机构200包括三条相互平行的滑轨201，滑轨201沿基座100长度方向设置，三条滑轨201均匀排列在基座100上。旋转模块102底面设有与滑轨201配合的滑块202，滑轨201嵌入滑块202内，这样只需拉动旋转模块102便可使得旋转模块102沿滑轨201长度方向滑移。优选地，滑轨201的长度介于基座100长度的三分之一至三分之二之间，但不仅限于此，只要旋转模块102抽出旋转时不触碰到床头板101皆可。
此外，滑轨201的数量不仅限于三根，两根或者更多皆可。
如图2和3所示，基座100上设有两个限位件105，两个限位件105分别位于滑动模块103滑移的初始位置和末端位置，这样当滑动模块103位于初始位置时，可以避免旋转模块102滑移。当滑动模块103位于末端位置时，方便工作人员转动旋转模块102。限位件105采用弹性定位销。
如图2和4所示，旋转机构300包括设置在滑动模块103与旋转模块102之间的旋转组件301，旋转组件301包括小旋转盘3011，小旋转盘3011顶面与旋转模块102固定连接，底面与滑动模块103固定连接，滑动模块103上还设有均匀环绕小旋转盘3011设置的旋转件3012，旋转件3012优选为万向球，其次可以选择万向轮等类似零件，旋转件3012一方面可以对旋转模块102进行支撑，另一方面旋转件3012本身可以自转相当于扩大了小旋转盘3011的作用面积。
如图2和5所示，滑动模块103上还设有两个对称设置的定位件104，定位件104 采用弹性定位销，旋转模块102底面设有与定位件104配合的定位槽106(见图5)，两个定位件104关于小旋转盘3011对称设置，两个定位件104的连线与滑动模块103的滑移方向垂直。这样当旋转模块102旋转180度后，正好将旋转模块102与滑动模块103相对固定，避免旋转模块102晃动。
如图3和5所示，支撑结构400为设置在基座100的顶边和底边的六个滚轮401，顶边与底边分别设有三个，三个滚轮401均匀排列设置，滚轮401采用单向滚轮401，安装时，将滚轮401安装成只能沿基座100长度方向运动的滚轮401。旋转模块102底面设有与滚轮401配合的凸块402，更换床单完毕，需要将旋转模块102推回初始位置时，稍微用力推动旋转模块102，使得旋转模块102稍稍抬起，此时凸块402便会与滚轮401抵触，这样可以限制旋转模块102左右方向旋转。
进一步地，位于基座100底边的滚轮401设置在滑轨201末端，这样当滑动模块103抽拉时，滚轮401对滑动模块103具有限位作用，这样可以限制滑动模块103进一步滑动脱离滑轨201。并且滚轮401采用胶轮材质，可以具有缓冲功能，避免滑动模块103与滚轮401刚性碰撞。
如图3和6所示，锁定机构500包括锁具501，锁具501包括安装在基座100上的锁座5011和安装在滑动模块103上的锁扣5012，锁座5011与锁扣5012相互配合，使用时，可推动滑动模块103，从而使得锁扣5012扣合在锁座5011上。
基座100上还安装有推动件502，推动件502为压簧5021，压簧5021位于滑动模块103朝向床头板101一侧，压簧5021一端固定在基座100上，另一端与滑动模块103顶部边沿抵触。这样当打开锁具501时，压簧5021便可自动将滑动模块103带旋转模块102推出，减少人工，省时省力。
具体实施过程：当需要更换床单时，打开锁具501，推动件502将滑动模块103连 带旋转模块102一起推出，旋转模块102通过滑动模块103沿滑轨201滑移，直至方便工作人员转动旋转模块102，并且旋转模块102在转动过程中不会触碰到床头板101，这样工作人员只需站在一个固定位置，便可转动旋转模块102，将床单塞入床垫与旋转模块102之间；更换完毕后，稍稍用力推动旋转模块102，使得旋转模块102底部的凸块402卡到基座100的滑移件204上，并且使得锁扣5012与锁座5011扣合，这样便可完成整个过程。
实施例2：一种便于更换床单的床架，与实施例1的不同之处在于，如图7所示，滑移机构200包括设置在基座100上的滑槽203，滑槽203沿基座100长度方向设置，滑槽203的条数设置成三条，三条滑槽203均匀设置在基座100上，滑槽203的条数不仅限于三条，根据实际情况需要，可设置成两条甚至更多。滑动模块103底面设有嵌入滑槽203的滑移件204，滑移件204可以为滑轮或者万向球，本实施例中滑移件204优选为滑轮，滑移件204可在滑槽203内滑动。这样旋转模块102便可沿滑槽203长度方向滑移，将旋转模块102抽出。
实施例3：一种便于更换床单的床架，与实施例1的不同之处在于，如图8所示，旋转组件301包括设置在滑动模块103中心处轴承座3013，旋转模块102上设有与轴承座3013转动连接的旋转轴3014，旋转轴3014与轴承座3013转动连接。这样旋转模块102便可进行旋转，方便更换床单。
实施例4：一种便于更换床单的床架，与实施例1的不同之处在于，如图9所示，旋转组件301包括大旋转盘3015，大旋转盘3015顶面与旋转模块102固定连接，底面与滑动模块103固定连接。旋转模块102可通过大旋转盘3015进行旋转方便更换床单。
实施例5：一种便于更换床单的床架，与实施例1的不同之处在于，如图10示，支撑结构400为两根定位辊403，两根定位辊403分别设置在基座100的顶边和底边， 且相互平行，定位辊403垂直于基座100长度方向设置，旋转模块102底面设有与定位辊403配合的凸条404，凸条404用于限制旋转模块102旋转。
安装时，稍稍用力推动旋转模块102，使得旋转模块102上的凸条404抵触定位辊403，这样就可以限制旋转模块102左右旋转。此外，位于底边的定位辊403设置在滑轨201末端，这样对旋转模块102具有限位作用，防止旋转模块102脱离滑轨201。
实施例6：一种便于更换床单的床架，与实施例1的不同之处在于，如图11所示，支撑结构400包括环绕基座100边沿设有的一圈支撑板架405，支撑板架405的顶面设有滑动件406。当将旋转模块102(见图2)抽出时，滑动件406可以减小旋转模块102(见图2)与支撑板架405之间的摩擦阻力。
滑动件406可以为万向轮或万向球或滑条，滑动件406主要为旋转模块102(见图2)在抽拉和旋转过程中，减少旋转模块102(见图2)受到的摩擦阻力，从而使得整个操作过程更加顺畅。
实施例7：一种便于更换床单的床架，与实施例1的不同之处在于，如图12所示，锁定机构500包括具有锁定功能的第二气弹簧503，第二气弹簧503安装在基座100上，第二气弹簧503的活塞杆顶端与滑动模块103固定连接。使用时，打开第二气弹簧503，第二气弹簧503与工作人员配合推动滑动模块103，当滑动模块103移动到能够使得旋转模块102自由旋转时，再将第二气弹簧503锁定，方便工作人员更换床单。
实施例8：一种便于更换床单的床架，与实施例1的不同之处在于，如图13所示，锁定机构500包括电动推杆504，电动推杆504固定安装在基座100上，电动推杆504的输出轴顶端与滑动模块103固定连接。使用时，电动推杆504将滑动模块103连带旋转模块102(见图2)推出，不需要人工推出旋转模块102(见图2)，极大地提高了工作效率。
实施例9：一种便于更换床单的床架，与实施例1的不同之处在于，如图14所示，锁定机构500包括安装在基座100上的气缸505，气缸505的活塞杆顶端与滑动模块103顶部边沿固定连接。使用时，只需驱动气缸505伸缩其活塞杆便可推出或者收回旋转模块102(见图2)，同时实现对旋转模块102(见图2)相对锁定，保持旋转模块102(见图2)稳定。
实施例10：一种便于更换床单的床架，与实施例1的不同之处在于，如图15所示，锁定机构500包括安装在基座100上伺服电机506，伺服电机506的输出轴上固设有丝杠507，旋转模块102(见图2)底面设有与丝杠507配合的丝杠座508，丝杠507与丝杠座508螺纹连接。基座100上设有两个用于限定滑动模块103滑移区间的限位传感器509，旋转模块102上设有与限位传感器509配合的限位卡块510。限位传感器509与限位卡块510配合，将滑动模块103限定在一定的范围内运动，这样可以避免旋转模块102(见图2)脱离基座100。
实施例11：一种便于更换床单的床架，与实施例1的不同之处在于，如图16所示，推动件502为第一气弹簧5022，第一气弹簧5022有两个，第一气弹簧5022底端固设在基座100上，其活塞杆的顶端与滑动模块103固定连接。
实施例12：一种便于更换床单的床架，与实施例1的不同之处在于，如图17所示，支撑结构400包括设置在基座100顶边和底边的支撑板条407，旋转模块102底面设有与支撑板条407抵触的限位板条408，限位板条408与支撑板条407的转角处倒角设置。支撑板条407与限位板条408配合限制旋转模块102左右滑动，并支撑旋转模块102。
上述的实施例仅仅是对本发明的解释，其并不是对本发明的限制，本领域技术人员在阅读完本说明书后可以根据需要对本实施例做出没有创造性贡献的修改，但只要在本发明的权利要求范围内都受到专利法的保护。
