下面结合图1-图12，对本公开的一些实施方式作详细说明。在不冲突的情况下，下述的实施例及实施例中的特征可以相互组合。
本提供一种快速连接机构，如图1-图12所示，包括快装板1、底座4和锁定结构；快装板1为锥台状，快装板1的较大底面上设置有卡接槽2，卡接槽2为锥形槽；底座4上设置有滑动槽16，快装板1卡接在滑动槽16内；锁定结构用于对进入滑动槽16内的快装板1进行固定；锁定结构包括锁定臂12、转动轴14和第一弹性件11；锁定臂12转动设置在转动轴14上，锁定臂12的一端与卡接槽2的内侧壁抵接，用于通过抵接实现对快装板1在滑动槽16内的锁定；第一弹性件11与锁定臂12连接，第一弹性件11用于对锁定臂12施加锁定快装板1方向的力。
在本实施例中，底座4可以是设置在云台上，快装板1通过螺丝等连接件与相机进行连接，进而能够实现快速将相机固定安装在云台上的目的。
具体的，在本实施例中，底座4上设置的滑动槽16，其为半通槽，即能 够使快装板1从底座4的一端进入滑动槽16，并沿滑动槽16的长度方向进行滑动，当滑动到滑动槽16的另一端后，被滑动槽16的侧壁阻挡无法滑动。
在本实施例中，快装板1包括两部分，分别为下部的卡接部与上部的连接部。其中，连接部用于将通过螺丝等连接件与相机等设备进行连接，卡接部用于与设置在底座4上的锁定结构连接，实现对快装板1的锁定。
具体的，在本实施例中，卡接部为锥台形状，滑动槽16为燕尾槽，进而能够通过滑动槽16与卡接部的配合，实现对卡接部在底座4上的上下方向的限位。
需要指出的是，本实施例中所述的上下方向为附图中所示的上下方向，与快速连接机构的使用状态下的上下方向无关。
在本实施例中，如图4所示，底座4上设置有容纳腔9，锁定结构设置在容纳腔9内，其中，转动轴14固定设置在容纳腔9内，且转动轴14的两端设置在容纳腔9的两个相对的侧壁上，锁定臂12的一端转动设置在转动轴14上，能够使另一端与卡接槽2的内侧壁相抵接，实现对快装板1的固定。
需要指出的是，锁定结构可以是设置在底座4的容纳腔9内，也可以是设置在底座4的下方，即底座4上只有滑动槽16，在滑动槽16的下方能够与外界连通，锁定结构通过底座4的下方与滑动槽16连通后，实现对快装板1的固定。
在本实施例中，如图5-图8所示，当快装板1在底座4的右侧进入滑动槽16后，快装板1的左侧的下端会与锁定臂12进行抵接，再快装板1进行向左滑动时，会对锁定臂12施加一个推力，进而使锁定臂12逆时针转动，进而使得快装板1能够与滑动槽16的最左端抵接，此时，快装板1下端的环形端面越过锁定臂12，锁定臂12在第一弹性件11的作用下，进行顺时针转动，返回初始位置，此时的锁定臂12的端部会与快装板1下部的卡接槽2的内侧壁进行抵接，使得快装板1不能从滑动槽16内向右侧滑动。
通过燕尾槽实现快装板1上下方向的限位，通过锁定臂12实现了快装板1左右方向的限位，进而保证了快装板1在底座4上的稳定性。
具体的，在本实施例中，第一弹性件11为扭簧，扭簧的一个伸出端与容 纳腔9的底部抵接，另一个伸出端与锁定臂12的下侧抵接，且扭簧套设在转动轴14上，如图3-图12所示。
由上述可以看出，在本实施例中，第一弹性件11对锁定臂12施加的力为锁定臂12绕转动轴14顺时针转动的力，也就是对锁定臂12施加锁定快装板1方向的力。
更具体的，为配合扭簧的功能，在本实施例中，将锁定臂12设置为U型，其设置有开口的一端与转动轴14进行连接，扭簧设置在U型的结构内部。
也就是说，在本实施例中，锁定臂12具体为U型的板状结构。
需要指出的是，在本实施例中，第一弹性件11可以是扭簧，但其不仅仅局限于扭簧，其还可以是其他的弹性装置，如还可以是压簧、拉簧等，其只要能够给锁定臂12一个向如图4-图12所示的顺时针转动的弹力即可。
还需要指出的是，在本实施例中，对锁定臂12施加顺时针转动的力为弹力，但其不仅仅局限于弹力，其也可以是其他部件提供的其他动力，如可以是使用气缸或油缸进行驱动，或使用磁力进行驱动，甚至还可以进行手动驱动等，也就是说，只要能够使得锁定臂12在常规状态下始终处于锁定位置即可。
在可选的实施方式中，底座4上设置有第一限位部5，在滑动槽16的滑入方向的前方，以及滑动槽16滑动方向的两侧。
具体的，为进一步保证快装板1在底座4上的稳定性，在滑动槽16的两侧以及端部设置了第一限位部5，如图2所示的左右方向以及图4-图12所示的滑动槽16左端的上方。
更具体的，在本实施例中，如图2所示，第一限位部5上具有一定的弧度或向滑动槽16内部方向倾斜的夹角，进而使得快装板1在进入到滑动槽16内后，能够被第一限位部5进行限定，保证快装板1在滑动槽16内的稳定性。
在可选的实施方式中，底座4上设置有解锁结构，解锁结构用于对锁定结构进行解锁。
快速连接机构不仅需要快速锁定，当锁定后也需要能够进行快速解锁，以提高整体的使用效率。
具体的，在本实施方式中，解锁结构包括解锁臂13；解锁臂13与锁定臂12连接，解锁臂13用于带动锁定臂12绕转动轴14转动，实现解锁功能。
解锁臂13的一端连接转动套，转动套套设在转动轴14上，使得转动套与转动轴14进行转动连接，进而使得解锁臂13能够带动转动套绕转动轴14进行转动。
锁定臂12的一端也与转动套的外壁固定连接，进而在解锁臂13带动转动套绕转动轴14进行转动时，会带动锁定臂12绕转动轴14进行转动。
当需要解锁时，解锁臂13绕转动轴14进行逆时针转动，带动锁定臂12也进行逆时针转动，进而使得锁定臂12能够与卡接槽2的内侧壁分离，进入到容纳腔9内，进而使得快装板1能够从滑动槽16内滑出。
在可选的实施方式中，解锁结构还包括解锁滑块6；解锁臂13和解锁滑块6均设置在容纳腔9内，容纳腔9上设置有与外界连通的解锁孔，解锁滑块6与解锁孔相对应设置；解锁臂13远离锁定臂12的一端与解锁滑块6的端部抵接。
在本实施例中，通过解锁滑块6能够带动解锁臂13绕转动轴14进行转动，进而能够降低解锁臂13的长度，进而减小解锁臂13的最大摆动范围，也就降低了整个底座4的体积。
具体的，在本实施例中，解锁滑块6在如图4-图12所示的右方向左方移动时，能够带动解锁臂13进行逆时针转动，带动锁定臂12进行逆时针转动，实现对快装板1的解锁。在可选的实施方式中，解锁滑块6靠近解锁臂13上设置有传动杆10，传动杆10与解锁臂13转动连接，传动杆10的侧壁与解锁滑块6的端部抵接。
在本实施例中，传动杆10转动设置在解锁臂13上，进而当解锁滑块6带动解锁臂13进行转动时，传动杆10外壁与解锁滑块6进行抵接，进而会跟随解锁滑块6的滑动而发生自转，且同时会带动解锁臂13绕转动轴14进行转动。
也就是说，这样的设置，能够降低解锁滑块6与解锁臂13之间的摩擦，提高了解锁臂13与解锁滑块6的使用寿命。
在可选的实施方式中，解锁结构还包括第二弹性件15，第二弹性件15与解锁滑块6连接，用于给解锁滑块6施加远离解锁臂13方向的力。
具体的，解锁滑块6远离解锁臂13方向为图4-图12中的由左向右的方向。
具体的，解锁孔内滑动设置有解锁按键8，解锁按键8的一端从解锁孔内伸出，解锁按键8与解锁滑块6固定连接。
在本实施例中，解锁滑块6的形状为如图3所示的L型，其一部分与传动杆10抵接，另一部分连接解锁按键8，且在解锁按键8的一端设置第二弹性件15，通过第二弹性件15能够实现解锁按键8的复位，进而实现解锁滑块6的复位，保证锁定臂12能够有足够的转动空间，进而保证能够对快装板1进行正常锁定。
具体的，在本实施例中，底座4上设置有盲孔，盲孔与容纳腔9连通，且解锁按键8的一端插入到盲孔内与第二弹性件15连接。
在本实施例中，解锁按键8为杆状结构，便于在盲孔内进行滑动。
更具体的，在本实施例中，第二弹性件15为压簧，压簧的一端与盲孔的底部抵接，另一端与解锁按键8的一端抵接。
在本实施例中，解锁滑块6也可以是设置在如图3所述的下方，此时可以通过改变解锁臂13的位置，或通过一些传动结构来实现锁定臂12的解锁。
具体的，在本实施例中，可以是将解锁臂13设置在解锁滑块6远离锁定臂12的一侧，即通过解锁滑块6的移动，带动解锁臂13向远离卡接槽2的方向转动，进而带动锁定臂12向远离卡接槽2的方向转动，实现锁定臂12的解锁。
具体的，在本实施例中，也可以是通过解锁滑块6与传动结构的配合来实现对锁定臂12的解锁。
更具体的，传动结构可以是齿轮齿条结构，如在解锁滑块6上设置齿条，在转动轴14上设置齿轮，通过齿轮齿条驱动，带动转动轴14转动，进而带动锁定臂12进行转动，实现解锁功能等。
需要指出的是，传动结构的设置方式有很多种，其可以是本实施例所述的 齿轮齿条方式，但其不仅仅局限于齿轮齿条结构，其只要能够实现通过解锁滑块6的移动，带动锁定臂12进行转动，进而实现对快装板1进行解锁的功能即可。
还需要指出的是，在本实施例中，第二弹性件15为压簧，但其不仅仅局限于压簧，其还可以是其他的具有弹性的结构，如还可以是使用拉簧、扭簧、弹片等，其只要能够给解锁按键8一个向底座4外部移动的动力即可。
还需要指出的是，在本实施例中，给解锁按键8提高向底座4外部移动的动力的装置是弹性件，其也可以是其他的部件，如还可以气缸、油缸、磁性装置等，也就是说，只要能够给解锁按键8一个始终朝向底座4外部移动的动力即可。
在可选的实施方式中，解锁滑块6上设置有第二限位部7，第二限位部7与快装板1靠近滑动槽16的槽底方向的一端抵接。
在本实施例中，第二限位部7用于限定快装板1上下方向的移动，保证快装板1在滑动槽16内的稳定性，减小安装虚位。
在可选的实施方式中，第二限位部7靠近快装板1的一端的形状为小于半球的球缺。
具体的，第二限位部7的上端为球缺形状，能够通过跟随解锁滑块6进行移动时，实现对快装板1进行不同强度的抵接，进而能够保证抵接后的快装板1的稳定性，减小安装虚位。
在使用时，快装板1在如附图所示的右方进入滑动槽16时，能够较为容易的从第二限位部7上方越过后，再与锁定臂12进行抵接。
当锁定臂12对快装板1进行锁定后，解锁臂13和第二弹性件15配合，会将解锁滑块6向右推动，使得第二限位部7向右推动，进而使得第二限位部7快装板1下方的抵接强度增加，进而增加了快装板1的安装稳定性，减小了安装虚位。
在可选的实施方式中，卡接槽2的槽口内沿设置有抵接面3，抵接面3与快装板1上靠近第二限位部7的一侧的表面之间所成的夹角为锐角。
具体的，锐角的角度为5°-15°，该角度的设计方便装配，优选的，锐角 的角度为10°。
也就是说，在本实施例中，卡接槽2的槽口内缘上设置有倒角，通过该倒角，能够保证第二限位部7与快装板1之间的抵接稳定性。
在可选的实施方式中，第二限位部7与解锁滑块6之间为可拆卸连接。
通过可拆卸连接，能够在快装板1不同的情况下，更换不同的第二限位部7来进行匹配，进而保证快装板1的安装稳定性，减小安装虚位。
具体的，可拆卸连接的方式可以是有很多种，如可以是卡接，也可以是螺纹连接等，只要能够实现第二限位部7与解锁滑块6之间的可拆卸连接，且保证第二限位部7与解锁滑块6之间的连接稳定性即可。
更具体的，在本实施方式中，第二限位部7在解锁滑块6上的凸出高度可调。
也就是说，第二限位部7的球缺部分与解锁滑块6之间的间距可调，使得其能够不需要更换第二限位部7的时候，也能够满足不同的快装板1的使用需求。
在本实施例中，调节的方式可以有很多种。
具体的，在本实施例中，第二限位部7包括螺杆和限位球缺，限位球缺设置在螺杆的一端，且在解锁滑块6上设置有螺纹孔，螺杆与螺纹孔配合，既能够实现限位球缺的高度调整，又能够实现对第二限位部7的固定定位。
需要指出的是，第二限位部7在解锁滑块6上的凸出高度的调节方式可以是上述的方式，但其不仅仅局限于上述一种方式，其还可以是其他的调节方式，也就是说，其只要能够实现第二限位部7的高度调节即可。
由上述可以看出，在本公开中的快速连接机构中，快装板1可以通过螺丝螺纹连接固定相机，本机构通过固定快装板1从而达到固定相机的作用。底座4包括主体和底板，底板通过螺丝固定在主体上，锁定臂12通过转动轴14铰接于底板上，转动轴14上设有扭簧使锁定臂12受力趋于顺时针旋转，解锁臂13的后端设有传动杆10，传动杆10可沿解锁滑块6的斜面滑动。解锁按键8和解锁滑块6通过螺丝固定，主体上设有盲孔(即解锁孔)，解锁按键8可以沿盲孔滑动，盲孔内部设有弹簧使解锁按键8受力向上运动。第二限位部7 通过外侧螺纹固定于解锁滑块6上随解锁滑块6运动。
在上述的几种实施例中，解锁按键8位于底座4上，且位于快装板1滑入滑动槽16内时，滑入方向所在的侧面上。
本公开还提供了另一种实施方式，如图13-图16所示，解锁按键8设置在快装板1滑入滑出方向的两侧，具体如下：
本实施例中，解锁按键8通过按键螺丝21固定在按键杆18上，按键杆18可以在底座4中滑动，按键杆18的内端通过固定螺丝19与平移滑块17连接，解锁滑块6通过连接轴20与解锁臂13转动连接，且解锁滑块6与平移滑块17之间具有相互配合的斜面。
当推动解锁按键8向底座内部进行轴向移动时，解锁按键8带动按键杆18，再带动平移滑块17进行同方向移动，在平移滑块17的斜面的作用下，带动解锁滑块6向上移动，解锁滑块6向上移动时，通过连接轴20带动解锁臂13绕转动轴14进行转动，带动锁定臂12向下转动，完成解锁动作。
快装板快速固定过程：如图5所示，快装板安装前锁定臂受扭簧弹力抵在主体上。如图6所示，快装板开始插入碰到锁定臂，锁定臂受力绕转动轴逆时针旋转。如图7所示，快装板继续进入，锁定臂完全被快装板底面压住，快装板开始挤压第二限位部带动解锁滑块和解锁按键一起向左滑动。如图8所示，快装板完全进入，锁定臂弹出抵住卡接槽的内侧壁，第二限位部抵住抵接面，主体上设置的第一限位部对快装板的上下方向进行限位，实现快装板的完全固定。
快装板快速取出过程：如图9所示，快装板被完全固定状态。如图10所示，按压解锁按键带动解锁滑块和第二限位部向左运动，解锁滑块向左运动挤压锁定臂上的传动杆，传动杆沿解锁滑块斜面向上滑动，使得解锁臂带动锁定臂绕转动轴进行逆时针转动，锁定臂与卡接槽的内侧壁分离，第二限位部与抵接面分离，此时的快装板可以自由取出。如图11所示，解锁按键和锁定臂复位。
图12为对快装板固定状态进行受力分析：
卡接槽的内侧壁上受的合力F 1可分解为F 2和F 3，由受力分析可得当F 3 大于F 2时即∠A小于45°锁定臂不会脱出斜面。
抵接面上受的合力F 4可分解为F 5和F 6，由受力分析可得当解锁滑块与底板的摩擦系数为μ时静摩擦力F静＝F6×μ。当μ＝1时F 静＝F 6，由受力分析可得当F 静大于F 5时即∠B小于45°解锁滑块不会向左滑动。
本公开实施例的有益效果是：
快装板1从滑动槽16的一端滑入后，通过抵接使锁定臂12在转动轴14上转动，当快装板1继续在滑动槽16内滑动时，锁定臂12在第一弹性件11的作用下，回弹进入到快装板1的卡接槽2内，且与卡接槽2的槽壁抵接，使得快装板1不能从滑动槽16内进行反向滑动，实现快装板1与底座4之间的快速装配，保证了快装板1与底座4之间的稳定性。
以上仅为本公开的优选实施例而已，并不用于限制本公开，对于本领域的技术人员来说，本公开可以有各种更改和变化。凡在本公开的精神和原则之内，所作的任何修改、等同替换、改进等，均应包含在本公开的保护范围之内。
