作为一个具体实施例，径向凸出结构包括自中心通孔内部下端可拆卸拧紧在连接段的下部的固定圈。
在一个具体实施方式中，至少一对插入配合结构包括位于横置枢纽套的外壁上的凸块和位于横置支座内壁上的与凸块配合的凹槽或通口，或者至少一对插入配合结构包括位于横置枢纽套外壁上的凹槽和位于横置支座内壁上的与凹槽配合的凸块。

在下文中被用于描述附图的某些方向性术语，例如“上”、“下”、“左”、“右”、“向上”、“向下”和其它方向性术语，将被理解为具有其正常含义并且指正常看附图时所涉及的那些方向。除另有指明，本说明书所述方向性术语基本按照本领域技术人员所理解的常规摄影摄像用支架的方向。
在本发明中的术语“约”、“大约”、“基本”和“几乎”将会被本领域普通技术人员理解且将根据用到该术语的上下文在一定范围内变化。
图1～3分别示出了本发明一个具体实施例的支架，其中图1示出了中轴10处于其竖置状态、支脚50处于工作位置；图2示出了中轴10处于其横置状态，且支脚50处于其工作位置；图3示出了中轴10处于其竖置状态且支脚50处于其收拢状态。
结合图4和图5所示，本实施例的用于摄影摄像器材的支架包括中轴10、具有轴向延伸的中心通孔41的本体座40以及支撑该本体座40的至少一条支脚50。尽管图中示出了支脚50的数量为3条，即为三脚架，但应当理解，支脚50的数量可以是其它数量，只要能够支撑中轴10及本体座40即可。如图所示，该支架还包括用于将该中轴10支撑在本体座40上的支撑机构。
支撑机构包括如此地与本体座40同轴布置的筒状的横置支座30，即横置支座30可绕其中心轴线相对于本体座40旋转但不能轴向相对移动地布置在本体座40上。横置支座30具有在其使用状态下始终处于本体座40上方的支撑段以及位于支撑段下方并套设在本体座40的中心通孔41内的连接段。横置支座30还具有与中心通孔41连通的轴向通孔34以及限定出该轴向通孔34的侧壁。支撑段在轴向通孔34的侧壁上设有向上开口的切口33和与该切口33径向完全对置的径向通孔38。轴向通孔34和中心通孔41的形状和尺寸被构造成可供中轴10的至少一部分穿过以实现竖直支撑中轴10的竖置状态。切口33和径向通孔38的形状和尺寸被构造成可供中轴10的至少一部分穿过以实现水平支撑中轴10的横置状态。优选地，横置支座30是一体形成的单件，例如是通过铸造工艺等一体成型的单独构件。
优选地，尽管图1、2和4所示，该切口33呈U形，该中轴10被构造成在其横置状态下正好被该切口33的底部和该径向通孔38的底部支撑。但应当理解，切口33还可以是任何可与径向通孔38相配合以将中轴10支撑在横置状态的形状，这不脱离本发明的保护范围。
采用本实施例的支架，当需要竖置该中轴10时，可将中轴10穿过横置支座30的轴向通孔34以及本体座40的中心通孔41以将中轴10支撑 在中轴10的竖置状态下。当需要横置该中轴10时，只需向上移动中轴10或者甚至将该中轴10自横置支座30中取出后，沿水平方向分别穿过切口33和径向通孔38即可实现。本实施例将中轴10居中地支撑在横向支座30和本体座40上，重心位于本体座40和横向支座30轴向方向上，支撑稳定、操作简单。此外，由于横置支座30在其使用状态，即在其与本体座40的连接状态下可相对于本体座40旋转，这样，当需要在水平方向上改变拍摄角度时，只需旋转横置支座30即可完成，方便了操作。
在一个具体实施例中，横置支座30还包括，以及介于支撑段与连接段之间的中间段。中间段在横置支座30的使用状态下始终处于本体座40上方。本体座40的中心通孔41的下端设置有下端开口的环形凹槽。连接段上设置有或可拆卸固定连接有沿径向伸入环形凹槽内的径向凸出结构。中间段、环形凹槽以及径向凸出结构被构造成，在横置支座30在其使用状态下中间段的下表面抵靠在本体座40上且径向凸出结构的上表面抵靠环形凹槽的底面，从而限制横置支座30与本体座40之间的相对轴向移动，但允许横置支座30与本体座40之间的相对旋转。
优选地，径向凸出结构是自中心通孔41内部下端例如通过螺纹可拆卸拧紧在连接段的下部的固定圈43。例如该固定圈43包括与该连接段螺纹连接的环形侧壁以及连接该环形侧壁的环形底座，该环形底座的内径大于所述环形侧壁的内径。
为了更方便地在横置状态和竖置状态间转换中轴10，优选地，支撑机构还包括横置枢纽套20，其在支撑段处可拆卸地安装在横置支座30的轴向通孔34内。在横置支座30与横置枢纽套20之间设有径向相对的两对插入配合结构。横置枢纽套20能围绕该两对插入配合结构的连接线相对于横置支座30旋转。中轴10的至少一部分能相对于横置枢纽套20轴向移动地套设在横置枢纽套20内并与横置枢纽套20一起在竖置状态与横置状态之间转动。此外，为了更加牢固地将中轴10锁定在其横置状态或竖置状态，优选地，支撑机构还包括中轴锁紧机构，其具有通过直接作用于横置枢纽套20以间接将中轴10锁紧在其竖置状态或横置状态的锁紧状态以及解锁该中轴10的解锁状态。
采用本实施例的支架，在安装时，首先将中轴10沿竖直方向向下插入 位于横置支座30内的横置枢纽套20内，进而插入到轴向通孔34和中心通孔41内，并可根据需要上下调整中轴10的位置并用中轴锁紧机构进行锁紧以将中轴10安装在合适的竖置状态。当需要横置该中轴10时，将中轴锁紧机构解锁至其解锁状态，并例如可通过向上移动中轴10以使得该中轴10相对于横置枢纽套20上移至合适的位置，使得中轴10和横置枢纽套20在轴向通孔34内绕两对插入配合结构的连接线旋转至与切口33和径向通孔38对准，此时沿水平方向移动中轴10使得中轴10分别穿过切口33和径向通孔38并利用中轴锁紧机构锁紧中轴10，以将中轴10固定在其横置状态下。
在一个可选实施例中，至少一对插入配合结构包括位于横置枢纽套20的外壁上的凸块23和位于横置支座30内壁上的与凸块23配合的凹槽31或通口。在另一个可选实施例中，至少一对插入配合结构包括位于横置枢纽套20外壁上的凹槽和位于横置支座30内壁上的与凹槽配合的凸块。
优选地，横置枢纽套20具有可收紧结构和/或由可伸缩材料制成，中轴锁紧机构通过径向向内挤压横置枢纽套20以夹紧并锁紧中轴10。在一个具体实施例中，如图4所示，可收紧结构包括沿其周向设置的至少一个凹口或切口24。
在一个具体实施例中，结合图5所示，横置枢纽套20的外壁上设置有径向完全对置的两个凸块23。横置支座30的内壁上与X方向上的左侧凸块23对应的位置上设置有与该左侧凸块23对应的凹槽31。横置支座30的内壁上与右侧的凸块23对应的位置上设置有通口，通口内设有内螺纹。中轴锁紧机构包括螺纹连接在该通口内的螺母36以及具有螺杆391的旋钮39。该右侧凸块23插入该螺母36内，该螺杆391与该凸块23相对地插入该螺母36内并能在该旋钮39的旋转过程中向内旋进并径向向内挤压该横置枢纽套20。
优选地，如图5所示，螺母36包括内径较大的光孔段和与该光孔段连接且内径小于该光孔段的螺纹孔段，所述光孔段和螺纹孔段之间形成为阶梯形内孔。凸块23插入光孔段内，螺杆391包括外径与光孔段对应的头部以及外径与螺纹孔段对应的杆部。螺杆391的头部伸入到光孔段内并与凸块23对置且无法穿过内径更小的螺纹孔段，以防止螺杆391旋落。为了方便旋拧该旋钮39，优选地，旋钮39还包括旋拧过程中始终处于螺 母36外侧的旋拧部以便于手持并旋拧。
在本实施例的使用过程中，当中轴10就位在沿Y向的竖置位置时，旋拧旋拧部以将螺杆391向内推进进而挤压横置枢纽套20，使得横置枢纽套20收缩并夹紧中轴10，以将中轴10锁紧在竖置状态。当需要将中轴10自竖置状态调整为横置状态时，只需沿相反方向旋拧该旋拧部以使得螺杆391朝外侧移动以放松对横置枢纽套20的挤压作用，进而中轴10可沿横置枢纽套20的内孔21轴向上移至可随横置枢纽套20一起在轴向通孔34内旋转时，旋转中轴10和横置枢纽套20至水平方向并嵌入切口33并穿过径向通孔38，再沿水平方向移动中轴10，以沿横置枢纽套20的轴向移动中轴10，进而调整中轴10至平稳的合适位置。当需要将中轴10自横置状态调整为竖置状态时，只需按相反的步骤进行即可。操作方便，支架稳定性好。
尽管图中仅示出了图5中左侧所示的插入配合结构包括位于横置支座30上的凹槽31和位于横置枢纽套20上的凸块23，而右侧的插入配合结构包括位于横置支座30上的通口和位于横置枢纽套20上的凸块23，并在通口的对应位置设置中轴锁紧机构以锁紧中轴10，但还可以想到，横置支座30的左右两侧均设置为通口，并分别在各通口的对应位置设置中轴锁紧机构以锁紧中轴10，当然也可以进一步在其它位置设置一个或多个中轴锁紧机构，或者横置支座30的左右两侧均设置为凹槽31，并分别在横置支座30的除凹槽31外的其它位置处设置中轴锁紧机构以锁紧中轴10，这均不脱离本发明的保护范围。
此外，尽管图4和5中示出了插入配合结构包括位于横置枢纽套20的外壁上的凸块23和位于横置支座30内壁上的与凸块23配合的凹槽31或通口，但还可以想到，该至少一对所述插入配合结构可以包括位于横置枢纽套20外壁上的凹槽和位于横置支座30内壁上的与所述凹槽配合的凸块，并将中轴锁紧机构在出横置支座30的凸块外的位置上安装在该横置支座30上以对横置枢纽套20进行挤压。也可以的是，横置支座30由可伸缩材料制成，并通过挤压该横置支座30的侧壁进而挤压横置枢纽套20来实现对中轴10的锁紧。此时，中轴锁紧机构可以安装在横置支座30的可实现挤压横置枢纽套20的任何合适的位置上，以上均不脱离本发明的保护范围。
为了方便旋转并保持横置枢纽套20，优选地，如图4和5所示，横置枢纽套20具有球形外壁22，横置支座30具有与横置枢纽套20的球形外壁22配合的球形内壁段32，即横置枢纽套20与横置支座30之间通过球面配合。横置枢纽套20的球形外壁22与横置支座30的球形内壁32配合，当中轴10穿过横置枢纽套20后，横置枢纽套20变形的范围变小不足以使横置枢纽套20的球形外壁22脱离横置支座30的球形内壁32的包络，从而达到限制横置枢纽套20的上下方向的运动的目的。
在本实施例中，中轴10包括用于安装摄影摄像器材的第一端、与第一端相对的第二端以及位于该第一端和第二端之间的中间部。优选地，中轴10的第二端具有端面12，端面12的外径略大于中间部的外径，横置枢纽套20的内径即使在其未收紧状态下也是小于中轴第二端端面12的外径的。横置枢纽套20具有下端面25。合适地，至少在当中轴10沿横置枢纽套20的轴向沿Y向向上移动至其端面12抵靠并被下端面25阻挡时，中轴10可以在轴向通孔34内绕两插入配合结构连接线旋转。
为了便于携带，优选地，支脚50的数量为三条，每条支脚50可枢转铰接在该本体座40上，并且支脚50至少具有从该本体座40径向向外展开所至的工作位置和从该工作位置起径向向内枢转所至的收拢位置。
在一个具体实施例中，如图4和5所示，包括中轴10、横置枢纽套20、横置支座30、指示圈80、旋钮39、螺母36、脚管件70、本体座40、用于将横置支座30锁紧在本体座40上的水平锁紧机构如水平锁紧旋钮60、固定圈43。横置支座30穿过本体座40后，从本体座40的下方安装固定圈43，固定圈43与横置支座30的下端连接段通过螺纹连接固定为一体，可在本体座40内水平旋转360度。水平锁紧旋钮60通过螺纹连接在本体座40上，施加力在横置支座30与本体座40配合的配合面上以在两者的配合面之间产生静摩擦力阻止横置支座30相对于本体座40的水平旋转，以达到锁紧横置支座30的目的。
横置枢纽套20上的凹口或切口24的目是为了横置枢纽套20能收缩变形装入横置支座30内，同时也是为了更好的锁紧中轴10。横置枢纽套20的两个凸台23对准横置支座30的凹槽31和通口装入，螺母36对准横置枢纽套20的凸台23后，通过螺纹与横置支座30连接固定。中轴10穿 过横置枢纽套20的内孔21。
采用本实施例的支架，当进行中轴10的横置时，移动中轴10至中轴10的端面12与横置枢纽套20的下端面25重合时，此时中轴10凸出在横置枢纽套20的下端面25以上的体积必须要在横置枢纽套20的球形外壁22所包络的范围内，否则不能横置中轴10。旋转中轴10带动横置枢纽套20，横置枢纽套20的两个凸台23一端固定在横置支座30的凹槽31上，另一端固定在螺纹连接在其通口内的螺母36上的光孔段内，横置枢纽套20的两个凸台23绕横置支座30的凹槽31和通口的连接线旋转运动，当中轴10旋转至横置支座30对应的让位的切口33时横置的中轴10便可穿过横置支座30对应的切口33和径向通孔38横置中轴10。
以上描述了本发明的优选的实施例，且这些实施例中的特征之间可以互换、替代或组合。
应当理解，虽然本说明书是按照各个实施例描述的，但并非每个实施例仅包含一个独立的技术方案，说明书的这种叙述方式仅仅是为清楚起见，本领域技术人员应当将说明书作为一个整体，各实施例中的技术方案也可以经适当组合，形成本领域技术人员可以理解的其它实施方式。
以上所述仅为本发明示意性的具体实施方式，并非用以限定本发明的范围。任何本领域的技术人员，在不脱离本发明的构思和原则的前提下所作的等同变化、修改与结合，均应属于本发明保护的范围。
