 本发明的最佳实施方式
下面根据附图所示实施方式阐述本发明。此次公开的实施方式可以认为在所有方面均为例示，不具限制性。本发明的范围不受以下实施方式的说明所限，仅由权利要求书的范围所示，而且包括与权利要求范围具有同样意思及权利要求范围内的所有变形。
如图1所示本发明云台快速锁紧装置实施例一立体分解结构示意图，包括锁紧圈1及通过滑轨机构可沿锁紧圈1内腔与所述锁紧圈1发生前后相对滑动的云台连接装置，云台连接装置通过锁紧机构在锁紧圈1内腔的相对滑动实现对云台连接装置的锁紧或云台连接装置的松脱。
结合图2所示，锁紧圈1包括矩形环状锁紧圈本体4，锁紧圈本体4的上表面沿内腔壁向上延伸有环状第一围板5，第一围板5的上端左、右侧对称设置有两个矩形开口槽6，本实施例中位于锁紧圈本体4的前侧设置有拉环7，锁紧圈本体4的外侧壁上设置有锁紧和松脱的方位指示图，当朝着拉环7所在方向拉动锁紧圈1时，可以使云台连接装置与锁紧圈1松脱，而当朝着远离拉环7的方向推动锁紧圈1时，可以使云台连接装置与锁紧圈1锁紧。
云台连接装置包括定位环8及连接在定位环8下面的云台连接件9，且从图1,7中可以看出，定位环8及云台连接件9同轴设置。结合图3所示，定位环8为盖形，定位环8的上表面靠近外缘部分的一周设有至少一个第一连接孔10，此实施例设置为四个，定位环8的上表面位于四个第一连接孔10之间的部位设有多个第二连接孔11，此实施例设置为三个。
结合图4所示，云台连接件9为环状，其具有中空的内腔，云台连接件9的内腔壁上朝内侧方向对称延伸有两个肋板12，两个肋板12上分别连接有垂直于肋板12的连接柱13，云台连接件9通过两个连接柱13向上穿过定位环8的两个第二连接孔11而与定位环8连接在一起。云台连接件9的内腔壁上沿周向设置有多个水平向的连接板14，各连接板14上分别设置有用于与云台连接的第三连接孔15。
云台连接件9通过滑轨机构在锁紧圈1的内腔壁相对前后滑动，云台连接件9通过锁紧机构在锁紧圈1滑动过程中实现对云台连接装置的锁紧或云台连接装置的松脱。滑轨机构为设置于云台连接件9外侧壁及设置于锁紧圈1内侧壁上的可相对滑动的凹凸配合结构。另一实施方式中，滑轨机构也可包括设置于云台连接件9外侧壁的至少一段第一凸条16和设置于锁紧圈1内腔壁的至少一段第二凸条17，所述第一凸条16位于所述第二凸条17上方，且可与第二凸条17之间发生相对滑动；具体的，本实施例中第一凸条16设置为三段，第二凸条17设置为一段，其中两个第一凸条16对称设置于云台连接件9的外表面左、右侧前部，第三个第一凸条16设置于云台连接件9的外表面前侧。云台连接件9通过三个第一凸条16在锁紧圈1的第二凸条17上面滑动。定位环8的外缘下端一圈设置有环状凸台35，环状凸台35与三段第一凸条16呈上下设置，即所述环状凸台35位于所述第一凸条16上方。当云台连接件9的三段第一凸条16滑出第二凸条17时，环状凸台35滑动设置于第二凸条17的上表面。
所述云台快速锁紧装置还包括锁紧机构，且所述锁紧机构包括对称设置于第一围板5左、右侧壁上的两个第一定位孔18、位于两个第一定位孔18内的两个第一弹性定位件19及沿前后相对滑动方向、设置于定位环8左、右侧壁上的滑槽20、第一定位槽21和第二定位槽22。两个第一弹性定位件19的一端穿出第一定位孔18后分别伸入两个滑槽20中，各滑槽20的前、后两侧分别设置有圆形第一定位槽21和第二定位槽22，锁紧圈1与定位环8在相对滑动过程中，两个弹性定位件19可沿滑槽20滑动至第一定位槽21或第二定位槽22以此实现对云台连接件9的锁紧或云台连接件9的松脱。
使用时，当需要将云台连接装置与锁紧圈1松脱时，结合图5所示，通过向拉环7方向拉动拉环7时，云台连接装置的云台连接件9上的第一凸条16沿锁紧圈1内腔的第二凸条17上相对向前滑动，第一弹性定位件19沿滑槽20相对滑动至第一定位槽21时，所述第一凸条16与所述第二凸条17完全错开，由定位环8和云台连接件9连接组成的云台连接装置置于锁紧圈1的松开端，云台连接件9可以自由滑出锁紧圈1，实现云台载荷的快速分离；而当需要将云台连接装置与锁紧圈1锁紧时，结合图6所示，通过向远离拉环7方向推动拉环7时，云台连接装置的云台连接件9上的第一凸条16沿锁紧圈1内腔的第二凸条17上相对向后滑动，第一弹性定位件19沿滑槽20滑动至第二定位槽22时，所述第一凸条16位于所述第二凸条17上方，由定位环8和云台连接件9连接组成的云台连接装置置于锁紧圈1的锁紧端，实现云台连接装置的锁紧,此时云台连接件9和定位环8的侧面均在锁紧圈1的滑槽内。
如图7所示本发明云台快速锁紧装置实施例二立体分解结构示意图，该实施例二与实施例一的不同之处仅在于，所述云台快速锁紧装置还包括固定板23。
结合图8所示，固定板23为圆板形状，固定板23设置于锁紧圈1的上方。固定板23上设有多个第三连接孔24，本实施例设置为四个，四个第三连接孔24与定位环8上的四个第一连接孔10位置上下对应，定位环8与固定板23之间通过四个螺栓25穿过多个第一连接孔10、四个第三连接孔24使二者连接在一起。固定板23的下表面左、右侧对称设置有与锁紧圈1的两个开口槽6位置对应的、且可沿所述开口槽6滑动的两个定位凸台26。
本实施例的云台连接装置与锁紧圈1之间的锁紧与松脱工作过程大部分相同，相同之处不再赘述，不同的是：在云台连接装置与锁紧圈1锁紧时，固定板23的两个定位凸台26滑动设于锁紧圈1的两个开口槽6内实现锁紧定位，而当云台连接装置与锁紧圈1松脱时，固定板23的两个定位凸台26滑出两个开口槽6。
如图9所示本发明云台快速锁紧装置实施例三立体分解结构示意图，本实施例与实施例二的不同之处仅在于：所述锁紧机构包括固定于锁紧圈1的锁紧圈本体4上表面左、右侧的两个第二弹性定位件27，弹性定位件27由定位件本体28及位于定位件本体28前、后端的V形弯折部29连接构成，锁紧圈本体4的左、右侧壁中部位置分别向外凸伸有一凸台，凸台上设置有贯通上、下端的螺孔，定位件本体28通过螺栓30穿过螺孔后固定于锁紧圈1的上表面，锁紧圈本体4上表面左、右侧与两个弹性定位件27的各V形弯折部29位置对应的部位分别设置有V形第一凹槽32，各第一凹槽32上靠近锁紧圈本体4内侧的部位分别开设有通孔31。
定位环8的上表面左、右侧对应四个V形第一凹槽32的位置设有V形第二凹槽33，且同侧的两个第二凹槽33之间还设置有V形第三凹槽34；当锁紧圈1与云台连接装置锁紧时，各第二弹性定位件27的两个V形弯折部29透过相应的两个通孔31后压在定位环8同一侧的两个V形第二凹槽33中，与所述定位环8抵持；
而当锁紧圈1与云台连接装置松脱时，各第二弹性定位件27的其中一个V形弯折部29分别压在定位环8一侧的对应的第三凹槽34中，另一个V形弯折部29悬空。
使用时，当需要将云台连接装置与锁紧圈1松脱时，结合图10和图11所示，通过向拉环7方向拉动拉环7时，云台连接装置的云台连接件9上的第一凸条16沿锁紧圈1内腔的第二凸条17相对向前滑动，两个弹性定位件27随锁紧圈1相对向前滑动，当弹性定位件27的两个弯折部29透过第一凹槽32上的通孔31由定位环8上的两个第二凹槽33向前滑动，其中一个V形弯折部29透过通孔31滑动至前端的第三凹槽34内，另一个呈悬空时，由定位环8和云台连接件9连接组成的云台连接装置置于锁紧圈1的松开端，实现云台连接装置从滑槽中的松开, 云台连接件9可以自由滑出锁紧圈1，实现云台载荷的快速分离；而当需要将云台连接装置与锁紧圈1锁紧时，结合图12和图13所示，通过向远离拉环7方向推动拉环7时，云台连接装置的云台连接件9上的第一凸条16沿锁紧圈1内腔的第二凸条17上相对向后滑动，两个弹性定位件27随锁紧圈1向后滑动，当弹性定位件27的两个弯折部29相对向后滑动，使得透过第一凹槽32上的通孔31位于定位环8的第三凹槽34内的弯折部29及另一个透过对应通孔31后悬空未与定位环8接触的弯折部29滑动至定位环8上的两个第二凹槽33内时，由定位环8和云台连接件9连接组成的云台连接装置置于锁紧圈1的锁紧端，实现云台连接装置在滑槽中的锁紧,此时，云台连接件9和定位环8的侧面均在锁紧圈的滑槽内。
