摄影支架第一实施例
如图1及图2所示，本申请提供了一种摄影支架10，该摄影支架10包括中心管100和支撑架200，中心管100的顶端用于安装摄影设备；支撑架200与中心管100连接，并靠近中心管100的底端设置，支撑架200能够相对中心管100沿中心管100的轴向移动，且支撑架200在沿中心管100的轴向并朝中心管100的底端移动预设行程以后继续朝中心管100的底端移动的过程中能够展开，支撑架200在沿中心管100的轴向并朝中心管100的顶端移动的过程中能够折叠。
本申请提供的摄影支架10，在使用时，用户可驱动支撑架200沿中心管100的轴向并朝中心管100的底端移动，以使支撑架200在沿中心管100的轴向并朝中心管100的底端移动预设行程以后继续朝中心管100的底端移动的过程中实现展开，从而以实现对摄影支架10的支撑，相比现有的支撑架边沿中心管的轴向滑动边展开的摄影支架而言，由于本申请的摄影支架10的支撑架200先沿中心管100的轴向并朝中心管100的底端移动预设行程以后再自动展开，因此本申请的摄影支架10的径向尺寸只有在支撑架200沿中心管100的轴向并朝中心管100的底端移动预设行程以后才会变大，使得本申请的摄影支架10能够在一些安装空间受限的特定场景(例如中间小、底部大的安装空间)正常展开，从而满足用户的使用需求，而当不需要使用该摄影支架10时，用户可驱动支撑架200沿中心管100的轴向并朝中心管100的顶端移动以实现对支撑架200的折叠，从而减小了摄影支架10占用的空间，实现折叠后的摄影支架10的小巧化，方便用户收纳和携带。
如图2及图3所示，支撑架200包括滑动座210和三个支撑腿220，滑动座210滑动套设于中心管100的外围，支撑腿220的一端转动连接于滑动座210上，三个支撑腿220间隔设置于滑动座210的外周，且当支撑腿220跟随滑动座210沿中心管100的轴向并朝中心管100的底端移动预设行程以后继续朝中心管100的底端移动的过程中，支撑腿220能够朝远离中心管100的方向转动并实现展开，当支撑腿220跟随滑动座210沿中心管100的轴向并朝中心管100的顶端移动的过程中，支撑腿220能够朝靠近中心管100的方向转动并实现折叠。需要解释说明的是，支撑腿220的数量也可以设置为其它数量，例如支撑腿220的数量还可以为二个、甚至三个以上。
具体地，当需要展开支撑架200时，只需要驱动滑动座210沿中心管100的轴向并朝中心管100的底端移动，当支撑腿220跟随滑动座210沿中心管100的轴向并朝中心管100的底端移动预设行程以后继续朝中心管100的底端移动的过程中，支撑腿220能够朝远离中心管100的方向转动并实现展开，与此同时支撑腿220与中心管100之间形成的夹角逐 渐增大，当支撑腿220与中心管100之间形成的夹角达到预设角度时，此时支撑架200为展开的最大程度；当折叠支撑架200时，只需要驱动滑动座210沿中心管100的轴向并朝中心管100的顶端移动，此时支撑腿220能够朝靠近中心管100的方向转动并实现折叠，与此同时支撑腿220与中心管100之间形成的夹角逐渐减小，当支撑腿220转动至与中心管100平行(即支撑腿220与中心管100之间形成的夹角减小至0度)时，此时支撑架200为折叠的最大程度。
如图3所示，具体在本实施例中，三个支撑腿220均匀间隔设置于滑动座210的外周。
如图4所示，支撑架200还包括三个第一转轴230，支撑腿220的一端通过第一转轴230转动连接于滑动座210上，支撑腿220能够相对滑动座210绕第一转轴230的轴向转动，三个第一转轴230分别与三个支撑腿220一一对应。
具体地，滑动座210的外周上间隔设置有三个第一安装槽212，第一转轴230连接设置于第一安装槽212的相对两内侧壁之间，三个第一安装槽212分别与三个第一转轴230一一对应，支撑腿220的一端转动套设于第一转轴230上。
支撑架200还包括三个第一弹性件240，第一弹性件240用于向支撑腿220提供弹力，以驱动支撑腿220朝靠近中心管100的方向转动，三个第一弹性件240分别与三个支撑腿220一一对应。通过第一弹性件240的设置，这样使得滑动座210在自然状态下(即无外力作用于滑动座210)，第一弹性件240在自身弹力作用下可驱动支撑腿220朝远离中心管100的方向转动以实现支撑腿220的自动展开。此外，当需要将支撑腿220从展开状态切换至折叠状态时。
具体地，第一弹性件240可以为扭簧，第一弹性件240套设在第一转轴230的外侧，第一弹性件240的一端抵持在支撑腿220上，第一弹性件240的另一端抵持在滑动座210上。进一步地，支撑腿220套设于第一转轴230的一端的侧部抵接在第一安装槽212的内侧壁上，第一弹性件240位于支撑腿220套设于第一转轴230的一端的相对的另一侧部和第一安装槽212的相对的另一内侧壁之间。进一步地，支撑腿220上设置有第一卡槽222，第一弹性件240的一端抵持在第一卡槽222内。
如图1、图2及图5所示，摄影支架10还包括套管300，套管300套设于中心管100的外围，套管300与中心管100同轴设置，支撑架200在展开状态时能够经套管300的底端开口伸出于套管300外，支撑架200在折叠状态时能够经套管300的底端开口缩回并收纳至套管300内。
具体地，当需要使用摄影支架10时，可使展开状态的支撑架200经套管300的底端开口伸出于套管300外，当不需要使用摄影支架10时，可使折叠状态的支撑架200经套管300的底端开口缩回并收纳至套管300内，相比传统的支撑架处于折叠状态时暴露在外部的设置方式，本申请通过设置套管300，使得折叠状态的支撑架200能够收纳在套管300内，从而可以提高摄影支架10的美观性，同时该套管300还能够对折叠状态的支撑架200起到一定的防护作用，避免其在运输和存放的过程中因暴露在外部发生磕碰造成损坏，而且还能够避免传统的支撑架处于折叠状态因暴露在外部而致使支撑架的相邻两个支撑腿之间出现缝隙易造成扎手的缺陷。
进一步地，支撑架200在折叠状态时，支撑架200能够经套管300的底端开口全部缩回至套管300内，即折叠状态的支撑架200能够全部收纳在套管300内，从而可以进一步提高摄影支架10的美观性。
如图2所示，在本实施例中，滑动座210滑动限位于套管300内，避免滑动座210在沿中心管100的轴向移动过程中从套管300的顶底两端的开口脱离出套管300。具体地，滑动座210能够与套管300的顶端内壁和底端内壁相抵持，以将滑动座210限位于套管300内。
进一步地，支撑架200在展开状态时，支撑架200的三个支撑腿220能够经套管300 的底端开口伸出于套管300外，支撑架200在折叠状态时，支撑架200的三个支撑腿220能够经套管300的底端开口缩回至套管300内。
如图1所示，进一步地，套管300的底端开口包括间隔设置于套管300的底端的三个过孔310，支撑腿220能够经过孔310伸出至套管300外或者缩回并收纳至套管300内，三个过孔310分别与三个支撑腿220一一对应。
如图5及图6所示，摄影支架10还包括锁紧组件400，锁紧组件400具有锁止状态和解锁状态，当锁紧组件400处于锁止状态时，锁紧组件400能够将折叠状态的支撑架200锁定于套管300内，以防止折叠状态的支撑架200意外展开；当锁紧组件400处于解锁状态时，锁紧组件400能够解除对折叠状态的支撑架200的锁定，以使得折叠状态的支撑架200能够展开从而使摄影支架10能够正常使用。
如图7所示，进一步地，套管300的侧壁上设置有通孔320，锁紧组件400包括锁扣410，锁扣410包括主体部411及与主体部411连接的锁扣部412，主体部411转动设置于套管300上，以使锁扣410在锁止状态和解锁状态之间进行切换。
当锁扣410处于锁止状态时，锁扣部412能够经通孔320伸入至套管300内并与支撑架200相卡持，以阻碍支撑架200相对中心管100及套管300沿中心管100的轴向移动，从而将折叠状态的支撑架200锁定于套管300内；当锁扣410处于解锁状态时，锁扣部412能够经通孔320伸出至套管300外并与支撑架200相分离，从而以解除对折叠状态的支撑架200的锁定。
具体地，初始时，锁扣410处于锁止状态，锁扣410的锁扣部412经通孔320伸入至套管300内并与支撑架200相卡持，锁扣部412能够阻碍支撑架200相对中心管100及套管300沿中心管100的轴向移动，从而将折叠状态的支撑架200锁定于套管300内。
当需要使用摄影支架10(即需要将支撑架200由折叠状态切换至展开状态)时，可驱使锁扣410的主体部411带动锁扣部412朝远离通孔320的方向转动，以将锁扣410由锁止状态切换至解锁状态，以使锁扣部412经通孔320伸出至套管300外并与支撑架200相分离，从而以解除对折叠状态的支撑架200的锁定，此时用户即可驱动支撑架200沿中心管100的轴向并朝中心管100的底端移动，以使支撑架200在沿中心管100的轴向并朝中心管100的底端移动预设行程以后，继续朝中心管100的底端移动的过程中经套管300的底端开口伸出于套管300外实现支撑架200的展开。
如图7所示，具体地，当锁扣410处于锁止状态时，锁扣部412能够与滑动座210相卡持，以阻碍滑动座210相对中心管100及套管300沿中心管100的轴向移动，从而将折叠状态的支撑架200锁定于套管300内。
如图7及图8所示，主体部411的顶端转动设置于套管300上，具体地，主体部411的顶端转动设置于套管300的顶端，主体部411背离套管300的一侧表面为曲面，主体部411的顶端的厚度大于主体部411的底端的厚度。
锁扣部412设置于主体部411的底端，并位于主体部411朝向套管300的一侧，锁扣部412朝向套管300的一侧表面为曲面，使得锁扣部412能够更顺畅地经通孔320移入或移出套管300，并且还能够降低对套管300和支撑架200的表面造成划伤的风险。具体在本实施例中，主体部411与锁扣部412一体成型设置，方便锁扣410的加工成型。
锁紧组件400还包括第二转轴420，主体部411通过第二转轴420转动设置于套管300上，主体部411能够相对套管300绕第二转轴420的轴向转动。
具体地，主体部411的顶端通过第二转轴420转动设置于套管300上，套管300的顶端设置有第二安装槽330，第二转轴420连接设置于第二安装槽330的相对两内侧壁之间，主体部411的顶端转动套设于第二转轴420上。
如图8所示，锁紧组件400还包括第三弹性件430，第三弹性件430用于向主体部411提供弹力，以使主体部411带动锁扣部412朝靠近通孔320的方向转动，从而以使锁扣部 412经通孔320伸入至套管300内并与支撑架200相卡持。通过第三弹性件430的设置，这样使得锁扣410在自然状态下(即无外力作用于锁扣410)，第三弹性件430在自身弹力作用下可驱使主体部411带动锁扣部412朝靠近通孔320的方向转动，从而以使锁扣部412经通孔320伸入至套管300内并与支撑架200相卡持，以将锁扣410切换至锁止状态，从而将折叠状态的支撑架200锁定于套管300内。此外，当需要将锁扣410从锁止状态切换至解锁状态时，通过用户的外力作用克服第三弹性件430施加在主体部411上的弹力，驱使主体部411带动锁扣部412朝远离通孔320的方向转动，从而以使锁扣部412经通孔320伸出至套管300外并与支撑架200相分离即可。
具体地，第三弹性件430可以为扭簧，第三弹性件430套设在第二转轴420的外侧，第三弹性件430的两端均抵持在主体部411上。进一步地，主体部411套设于第二转轴420的一端(即主体部411的顶端)的侧部抵接在第二安装槽330的内侧壁上，第三弹性件430位于主体部411套设于第二转轴420的一端的相对的另一侧部和第二安装槽330的相对的另一内侧壁之间。进一步地，主体部411上设置有第二卡槽413，第三弹性件430的一端抵持在第二卡槽413内。
如图2及图7所示，摄影支架10还包括第二弹性件500，第二弹性件500设置于套管300内，第二弹性件500用于驱动支撑架200沿中心管100的轴向并朝中心管100的底端移动。通过第二弹性件500的设置，这样使得支撑架200在自然状态下(即无外力作用于支撑架200)，例如在一些场景中，用户将锁扣410由锁止状态切换至解锁状态以后，第二弹性件500在自身弹力作用下即可驱使支撑架200沿中心管100的轴向并朝中心管100的底端移动，以使支撑架200在沿中心管100的轴向并朝中心管100的底端移动预设行程以后，继续朝中心管100的底端移动的过程中经套管300的底端开口伸出于套管300外实现支撑架200的自动展开，提高摄影支架10的自动化和便捷化性能。此外，当需要将支撑架200从展开状态切换至折叠状态时，通过用户的外力作用克服第二弹性件500施加在支撑架200上的弹力，驱使支撑架200沿中心管100的轴向并朝中心管100的顶端移动即可将支撑架200切换至折叠状态，并使得该折叠状态的支撑架200经套管300的底端开口缩回并收纳至套管300内。
具体地，第二弹性件500可以为压缩弹簧，第二弹性件500套设在中心管100的外围，第二弹性件500的一端抵持在套管300的顶端内壁上，第二弹性件500的另一端抵持在滑动座210上，第二弹性件500用于向滑动座210提供弹力，以驱动滑动座210相对中心管100及套管300沿中心管100的轴向并朝中心管100的底端移动。
如图9所示，进一步地，中心管100包括依次套接的多个连接管110，其中一个连接管110能够相对相邻的另一个连接管110沿中心管100的轴向伸缩，以使中心管100的支撑长度沿中心管100的轴向可调。具体地，摄影或拍摄过程中，中心管100的顶端上的摄影设备经常需要调节其高度，通过多个连接管110之间的依次套接，可以通过调节中心管100的支撑长度来实现中心管100的顶端上的摄影设备的高度调节。在一实施例中，中心管100的顶端用于连接云台，摄影设备能够安装在云台上。
摄影支架第二实施例
参考图10至图13，图10至图13示意摄影支架10第二实施例的示意图。
本实施例的摄影支架10与第一实施例的结构相似，不同之处在于本实施例的支撑腿220在套管300的底端展开的驱动原理不同。本实施例中，支撑腿220的末端可以不用设置第一实施例中的第一弹性件240，即支撑腿220的自动撑开不一定靠弹簧力作用。取而代之的是，本实施例摄影支架10还包括驱动滑块600和齿轮700，驱动滑块600设置于中心管100且能够沿着中心管100的轴线方向移动，驱动滑块600靠近套管300的顶端且通过第二弹性件500与套管300连接，驱动滑块600包括齿条610，第二弹性件500能够释放弹性力，以使驱动滑块600带动滑动座210沿中心管100的轴线方向朝中心管100底端 移动。齿轮700与支撑腿220的末端固定连接，齿轮700和齿条610的数量与支撑腿220的数量一一对应，在驱动滑块600带动滑动座210移动至套管300底端时，齿条610会继续相对滑动座210沿着轴向移动，进而齿条610通过沿轴向的移动能够带动齿轮700转动以使支撑架200展开。
需要说明的是，驱动滑块600还包括固定座620，齿条610设置于固定座620远离第二弹性件500的一侧，同时齿条610的长度延伸方向与中心管100的轴向方向平行。图6示意了固定座620为两端开口的中空结构，固定座620套设于中心管100，固定座620能够沿着轴向带动齿条610同步移动。可以理解，在其它实施例中，固定座620还可以与中心管100设置的滑轨配合，此时固定座620可以与中心管100并排设置而不一定套设于中心管100。其中，固定座620的外形结构为圆柱体，可以理解，在其它实施例中，固定座620外形结构可以为正方体、长方体等。本申请对固定座620的外形结构不作任何限定。在固定座620呈圆柱状时，固定座620能够与套管300的内壁更好配合。图12还示意了齿条610的数量为多个，多个齿条610沿着固定座620的周向间隔排布。可以理解，齿条610的数量还可以设置为一个、二个等等。
一实施例中，图13示意了套管300的底部设置有多个第一开口301，第一开口301的设置数量与支撑腿220的设置数量一一对应，多个第一开口301沿套管300的周向间隔排布，支撑腿220能够穿设于第一开口301，以使支撑腿220能够在套管300的外围进行展开。进一步，中心管100的底部设置有多个第二开口101，第二开口101的设置数量与第一开口301的设置数量一一对应，多个第二开口101沿中心管100的周向间隔排布，支撑腿220能够穿设第二开口101，以使支撑腿220能够在套管300的外围进行展开。
摄影支架第三实施例
参考图14和图15，图14和图15示意摄影支架10第三实施例的示意图。
本实施例的摄影支架10与第二实施例的结构相似，不同之处在于本实施例的支撑腿220在套管300的底端展开的驱动原理不同。本实施例中，支撑腿220末端设置的齿轮700可以被凸轮800替代，凸轮800与支撑腿220的末端连接固定，支撑架200处于折叠状态下，凸轮800凸设于滑动座210，驱动滑块600设置于中心管100且能够沿着中心管100的轴线方向移动，驱动滑块600靠近套管300的顶端且通过第二弹性件500与套管300连接。第二弹性件500能够释放弹性力，以使驱动滑块600带动滑动座210沿中心管100的轴线方向移动，在驱动滑块600带动滑动座210移动至套管300底端时，驱动滑块600会继续沿着轴向相对滑动座210和凸轮移动，驱动滑块600施加外力于凸轮800，以使凸轮800带动支撑腿220转动且在套管300底端展开。
摄影支架第四实施例
参考图16至图19，图16至图19示意摄影支架10第四实施例的示意图。
参考图16，本实施例提供了一种摄影支架10，用于安装拍摄设备，拍摄设备可以但不限定为相机或手机，摄影支架10能通过人手进行抽拉，以实现摄影支架10的折叠和展开，参考图16，当摄影支架10处于折叠状态时，摄影支架10可以被单手握持且方便收纳。参考图17，当摄影支架10处于展开状态时，摄影支架10可以将拍摄设备支撑于平整或不平整的桌面和地面。
参考图17和图18，摄影支架10包括中心管100、支撑架200和锁紧组件400，中心管100具有沿轴向排布的第一端130和第二端140，第一端130可以被理解为用于安装拍摄设备的端部，第二端140可以被理解为朝向或靠近地面和桌面的端部。支撑架200能够沿着中心管100的轴向在第一端130与第二端140移动，以使支撑架200能够在第一端130处于折叠状态，并使支撑架200在第二端140处于展开状态，锁紧组件400用于在折叠状态下保持支撑架200与中心管100的相对固定，并且锁紧组件400还能够解除支撑架200与中心管100的相对固定，以使支撑架200能够展开。
中心管100的顶部是供拍摄设备安装的部位，中心管100的顶部可以设置带有快装结构的安装座，快装结构可以包括冷靴口、云台、螺纹轴、螺纹孔中的至少一种，中心杆100可以通过安装座上设置的快装结构安装摄影配件，中心管100的材质可以但不限为合金、不锈钢、塑料等。中心管100设置为中空结构，这一设置一方面可以减轻摄影支架的重量，另一方面中空结构可以容纳摄影支架的其它零部件。在一实施例中，中心管100包括第一管150和第二管160，第二管160位于第一管150内部并能够伸出或收纳于中心管100，用户可以根据拍摄需要调整第二管160在第一管150内的伸缩来调整中心管100的高度。
支撑架200包括滑动座210、多个支撑腿220、第二弹性件500，多个支撑腿220转动连接于滑动座210，滑动座210能够沿着中心管110的轴向在第一端130与第二端140之间移动，以带动支撑腿220在第一端130处于折叠状态，在第二端140处于展开状态。第二弹性件500与滑动座210连接，第二弹性件500能在折叠状态下积蓄弹性力，图18示意了第二弹性件500位于滑动座210背向支撑腿220的一侧，中心管100靠近第一端130的位置设置有凸块111，在折叠状态时，第二弹性件500处于在凸块111和滑动座210之间被压缩的状态，凸块111作为设在中心管100第一端130附近的限位件，其作用是当第二弹性件500运动到附近时，对第二弹性件500进行限位并挤压第二弹性件500，在其它实施例中凸块111可以设置为其它形式的限位件。需要理解，在其它实施例中，第二弹性件500也可以设置在滑动座210面向支撑腿220的一侧，此时第二弹性件500的一端与滑动座210固定连接，另一端与中心管100固定连接，折叠状态的第二弹性件500被拉伸而积蓄弹性力。
需要说明的是，第二弹性件500可以装设在中心管100的内部，也可以围绕在中心管100的外部，图18示意了第二弹性件500是套设于中心管100的弹簧，可以理解，第二弹性件500也可以是装设在中心管100的弹片或弹性垫。另外，第二弹性件500的数量可以设置为一个或者周向间隔的多个。
在一实施例中，滑动座210为圆柱环状，其内径稍大于中心管100的外径，并套设于中心管100的外部，在其它实施例中，滑动座210也可以设置有伸入中心管100内部的滑块，中心管100上设置轨道，滑动座210通过滑块沿轨道移动。为了便于人手对摄影支架进行抽拉，摄影支架10上还设置了牵引件910，牵引件910与滑动座210连接，牵引件910能够带动滑动座210沿中心管100的轴向滑动，在一实施例中，牵引件910呈管状结构，牵引件910套设于中心管100并与中心管100围合形成容纳空间920，第二弹性件500位于容纳空间920并能随牵引件910的带动积蓄和释放弹性力，可以理解，在其它实施例中，牵引件910也可以是手柄等其它方便人手操作的结构。需要说明的是，对于前文所述摄影支架10还包括套管300的实施例而言，此时的牵引件910可以至少部分结构收容于套管300内并可在套管300内滑动。
锁紧组件400能够在折叠状态下保持滑动座210与中心管100的相对固定，同时使第二弹性件500处于被固定并积蓄弹性力的状态，在需要对摄影支架进行展开时，锁紧组件400还能够解除滑动座210与中心管100的相对固定，使滑动座210能够在第二弹性件500释放弹性力的作用下滑动并带动支撑腿220展开，对于第一实施例而言，支撑腿220在中心管100底端展开。
锁紧组件400包括第一锁合件440和第二锁合件450，第一锁合件440设置于中心管100，第二锁合件450设置于支撑架200，在折叠状态时，第一锁合件440伸出于中心管100以使支撑架200与中心管100保持相对固定，在一实施例中，牵引件910的一端与滑动座210连接并形成卡接位211，第一锁合件440伸出于中心管100并伸入卡接位211中使支撑架200与中心管100保持相对固定。第二锁合件450活动设置于卡接位211，第二锁合件450能够被按压以带动第一锁合件440向中心管100内缩，第一锁合件440脱离卡接位211，第二弹性件500释放弹性力并能够带动支撑腿220完成展开动作。
图18示意了卡接位是滑动座210和牵引件910之间形成的台阶213，第二锁合件450为活动设置在卡接位上的按键321，第一锁合件440伸入卡接位的同时抵持在按键321上，并由于台阶213与第一锁合件440相互干涉，阻挡滑动座210的滑动，从而使支撑架200与中心管100保持相对固定，在需要对摄影支架10进行展开时，按压按键321，可促使按键321带动第一锁合件440内缩，此时就可以使第一锁合件440脱离卡接位211，同时第二弹性件500释放弹性力驱使滑动座210相对于中心管100滑动，并带动支撑腿220展开。第二锁合件450起到了能使第一锁合件440向中心管100内缩的作用，在其它实施例中，第二锁合件450也可以是反向拉动第一锁合件440的拉环等，卡接位也可以是卡槽等其它能固定第一锁合件440的结构。
综上所述，本发明实施例提供的摄影支架10能够安装拍摄设备，拍摄设备可以但不限定为相机或手机，摄影支架10能通过人手进行抽拉，以实现摄影支架10的折叠和展开，当摄影支架10处于折叠状态时，摄影支架10可以被单手握持且方便收纳。当摄影支架10处于展开状态时，摄影支架10可以将拍摄设备支撑于平整或不平整的桌面和地面。
参考图18和图19，第一锁合件440包括中心件311和第四弹性件312，中心件311在第四弹性件312的弹性力作用下伸出中心管100，中心件311被按压向中心管100内缩时，第四弹性件312积蓄弹性力，解除按压之后，中心件311能够在第四弹性件312的弹性力作用下重新伸出中心管100。牵引件910和中心件311的伸出端313中的至少一者设置有斜面314，滑动座210沿中心管100的轴向从第二端140运动到第一端130的过程中，牵引件910和中心件311的伸出端313发生干涉，中心件311通过斜面314被挤压向中心管100内缩，当中心件311与卡接位211对位时，中心件311能够在第四弹性件312的弹性力作用下伸出中心管100并卡接于卡接位211，图18示意了斜面314设置在中心件311的伸出端313上，在其它实施例中斜面314也可以设置在牵引件910上，或者在牵引件910和中心件311的伸出端均设置斜面314。
在一实施例中，第一锁合件440装设在中心管100的内部，中心管100上开设有第一通孔151和第二通孔152，第一通孔151供中心件311的伸出313端穿过，第二通孔152供中心件311上远离伸出端313的一端穿过，中心件311的伸出端313伸出或者内缩于第一通孔151的过程中，其另一端也会在第二通孔152内伸缩，第二通孔152提供了中心件311在中心管100内伸缩的空间，在其它实施例中，第二通孔152可以仅设置为不贯通中心管100的凹槽。中心件311上位于中心管100内部且靠近第一通孔151的一侧设置有凸台315，第四弹性件312的一端抵持于凸台315，第四弹性件312另一端抵持于中心管100上第二通孔152的周围，当中心件311被挤压内缩时，第四弹性件312通过凸台315被压缩并积蓄弹性力，中心件311能够通过凸台315在第四弹性件312的弹性力作用下重新伸出中心管100。在其它实施例中，第四弹性件312也可以通过被拉伸的方式积蓄弹性力，这种情况下，第四弹性件312的两端分别与凸台315和第一通孔151的周围固定连接。第四弹性件312可以围绕在中心件311的外部，也可以装设在中心件311的内部，图18示意了第四弹性件312是套设于中心件311的弹簧，可以理解，第四弹性件312也可以是装设在中心件311的弹片或弹性垫。另外，第四弹性件312的数量可以设置为一个或者周向间隔的多个。
继续参考图19，中心管100还设置了弧形条170，弧形条170位于中心管100内部并且占据中心管100的部分长度，第二通孔152开设在弧形条170上，第一锁合件440能够通过弧形条170装设入中心管100内。弧形条170的设置是为了将第一锁合件440装设在其中，并进一步装设入中心管100内，在不设置弧形条170的情况下，直接在中心管100内部装设第一锁合件440会有诸多不便，弧形条170的设置另一方面节省了加工所需要的材料和成本。在一实施例中，弧形条170上设置加厚区171，第二通孔152开设在加厚区171，进而使中心件311在第二通孔152内有更大的活动空间。在其它实施例中，弧形条 170也可以是管状结构，第一锁合件440装设在管状结构的端部，同样可以达到方便装设于中心管100的目的，这时弧形条170上不仅需要开设第二通孔152，还需要开设第一通孔151。
在一实施例中，支撑架200还包括连杆250，连杆250的数量与支撑腿220的数量相等，连杆250的两端分别转动连接于中心管100和支撑腿220，由于支撑腿220的一端连接于滑动座210上，滑动座210和中心管100之间相对运动时，连杆250可以带动所有支撑腿220同步打开或闭合，在其它实施例中，可以通过在支撑腿220上设置绳索牵引等方式，使支撑腿220达到同步展开和闭合的效果。支撑腿220设置为弧形条状并在折叠状态下形成管柱体，支撑腿220能在折叠时将中心管100和连杆250闭合在支撑腿220内侧，使摄影支架10在收纳后更加美观且便于携带，在其它实施例中，支撑腿220也可以设置为任意的形状。
摄影支架第五实施例
本实施例的摄影支架10与第一实施例的结构相似，不同之处在于本实施例锁紧组件400与第一实施例的锁紧组件400的结构不同。本实施例中，锁紧组件400包括第一锁合件440和第二锁合件450，第一锁合件440和第二锁合件的具体结构可以参考摄影支架10第四实施例的相关描述，此处不再赘述。
以上仅为本发明的优选实施例，并非因此限制本发明的专利范围，凡是在本发明的发明构思下，利用本发明说明书及附图内容所作的等效结构变换，或直接/间接运用在其他相关的技术领域均包括在本发明的专利保护范围内。
