为了说明本申请所述的立式支撑结构技术方案，以下结合具体附图及实施例进行详细说明。
请参照图1至图10，现对本申请提供的立式支撑结构和采用该立式支撑结构的LED会议屏进行示例性说明。立式支撑结构用于支撑目标结构50，并使目标结构50呈立式放置状态。在该立式支撑结构运用于LED会议屏时，目标结构50为显示屏。本实施例提供的立式支撑结构，也可以用于支撑展板或其它结构，在此不作限定。
可以理解，目标结构50呈立式放置状态，在水平投影上宽度明显小于长度，使得目标结构50容易向宽度方向的一侧倾倒，因此，立式支撑结构需要着重对抗倾倒能力进行设计。本实施例提供的立式支撑结构，适用于呈立式放置状态的目标结构50，但不排除对呈卧式放置状态的目标结构50的适用。
立式支撑结构包括上下设置的固定架10和支撑件20，以及连接固定架10和支撑件20的连接组件30。
固定架10用于固定目标结构50。固定架10的具体结构可根据目标结构50进行设计，可以为矩形框架、支撑板或桁架等，在此不作限定。
支撑件20至少有两个并沿固定架10的长边间隔设置，各支撑件20包括两个分立的支腿21，并在两个支腿21的连接位置设有插接孔201和连接孔202。插接孔201开设于支撑件20的上表面，连接孔202开设于支撑件20的侧表面。连接孔202与插接孔201连通。
连接组件30包括连接柱31和螺丝32，连接柱31连接固定架10下表面并与插接孔201插接配合，连接柱31在其外侧表面开设有至少两个螺接孔301。
其中，在连接柱31与插接孔201插接配合时，支撑件20能够相对连接柱31转动而使各螺接孔301能够顺次经过连接孔202，在任一螺接孔301与连接孔202正对时，螺丝32穿过连接孔202与螺接孔301螺接，且各支腿21与地面抵接的支点不共线。
需要说明的是，各支腿21与地面抵接的支点不共线，是指各支腿21与地面抵接的支点顺次连接所形成的图形不是直线。或者说，所有支点不会落在同一直线上。
本实施例中，连接柱31与固定架10可以一体设置，或采用焊接、螺接等方式固定连接。在此不作限定。
支撑件20具有两个支腿21，两个支腿21平行或形成一定的夹角。支撑件20至少有两个。图示结构中，支撑件20有两个，而使立式支撑结构具有四个支腿21，即四个与地面接触的支点。四个支点共线的情况发生于各支撑件20的两个支腿21在水平投影上共线，且平行于两个支撑件20分别与固定架10的连接点的连线。为便于描述，将该两个支撑件20分别与固定架10的连接点的连线在水平面的投影命名为中线。四个支点共线的情况下，立式支撑结构处于不稳定的状态，很容易向中线的两侧发生倾倒。可以理解，在四个支点不共线的情况下，四个支点位于中线的两侧，或部分支点位于中线而其它支点位于中线的一侧。位于中线一侧的支点为立式支撑结构提供向上的支撑力，并为立式支撑结构提供抗倾覆的力矩。在中线的两侧均存在支点的情况下，两侧的支点为立式支撑结构提供方向相反的力矩而阻碍立式支撑结构向中线的两侧倾倒。可以理解，支点与中线的距离越远，则所能提供的力矩越大，立式支撑结构的稳定性越好。但是，支点越远，则立式支撑结构放置于地面所占用的空间相对越大，本实施例中，立式支撑结构占用空间主要是指立式支撑结构放置于地面时，四个支点连线在水平面的投影形状，尤其是垂直于中线的宽度方向的尺寸。
结合使用环境，采用本实施例提供的立式支撑结构，操作人员可以根据现场情况调整支撑件20与固定架10的角度。在安装空间不受限制的情况下，支撑件20的两个支点调整为远离中线设置，而在安装空间受限的情况下，将支撑件20的两个支点向中线靠拢。比如在水平投影呈三角形的安装空间，可以将一个支撑件20的两个支点远离中线设置而另一个支撑件20的两个支点靠近中线设置。在水平投影呈矩形的安装空间，调整两个支撑件20使得对应的四个支点，使得四个支点位于安装空间的宽度范围内。
由上，本实施例提供的立式支撑结构，插接孔201和连接柱31的配合设置使得支撑件20和固定架10能够相对转动，从而调整支腿21相对固定架10的角度。多个螺接孔301的设置，使得支腿21和固定架10能够在特定的多个角度中择一进行固定连接。本实施例提供的立式支撑结构，由于支撑件20与固定架10的角度可调节，使得立式支撑结构与地面接触的四个支点的连线所形成的多边形的宽度尺寸可调节，从而能够适用于安装环境受限或不受限制的情况，提高立式支撑结构的适用性。
本实施例中，任一支撑件20的两个支腿21在水平投影上不共线。两个支腿21延伸线在水平投影上的夹角A是指两个支腿21延伸线所形成的小于或等于90度的角。本实施例中，两个支腿21延伸线在水平投影上的夹角A不等于0。该设置使得无论支撑件20与固定架10处于哪个角度，立式支撑结构的四个支点不共线。在其它实施例中，支撑件20的两个支腿21在水平投影上共线设置，两个支腿21分别位于中线的两侧。换言之，两个支腿21延伸线在水平投影上的夹角A等于0。在两个支腿21在水平投影上共线的情况下，对螺接孔301的开设位置应避开能够使支腿21与固定架10长度方向平行的情形（避开四个支点共线的情形），即，螺接孔301的开设位置受限。而两个支腿21在水平投影上不共线的情况下，立式支撑结构的四个支点不会发生共线的情况。
图2或图5所示结构中，任一支撑件20的两个支腿21分别位于固定架10的两侧。该情况下，无论支撑件20与固定架10处于哪个角度，中线的两侧均存在支点。换言之，支撑件20的安装角度不受限制。在其它实施例中，支撑件20的两个支腿21均位于固定架10的同一侧，该情况下，两个支撑件20在安装时，一个支撑件20的两个支腿21位于固定架10的一侧而另一个支撑件20的两个支腿21位于固定架10的另一侧，以共同实现对目标结构50的支撑。换言之，该设置下，支撑件20的安装角度受限。
优选的，任一支撑件20的两个支腿21分别位于固定架10的两侧且在水平投影上的夹角A为15°-45°。
可以理解，支撑件20与固定架10转动而其两个支点在垂直于中线的宽度方向具有最远距离和最近距离。最远距离和最近距离的差值为支撑件20所占用空间的调整范围。此外，两个支点在垂直于中线的宽度的距离越大，则立式支撑结构的抗倾覆能力越好。
在支腿21分别位于固定架10的两侧的情况下，两个支腿21在水平投影上的夹角A等于0时，最长距离为两个支腿21垂直于中线的情况且最长距离为两个支腿21在水平投影的长度之和，最短距离为两个支腿21与中线重合的情况且最短距离为零。支撑件20具有最大的空间调整范围。两个支腿21在水平投影上的夹角A等于90°时，最短距离为其中一支腿21垂直于中线的情况，且最短距离为该支腿21在水平投影的长度，最长距离为任一支腿21与中线呈45°的情况。支撑件20具有最小的空间调整范围。
两个支腿21在水平投影上的夹角A越接近0°，则支撑件20的最远距离越大而最近距离越小，支撑件20的空间调整范围越大。反之，两个支腿21在水平投影上的夹角A越接近90°，则支撑件20的最远距离越小而最近距离越大，支撑件20的空间调整范围越小。将两个支腿21在水平投影上的夹角A优选为15°-45°，能够兼顾立式支撑结构的抗倾覆能力并具有较大的空间调整范围。本领域技术人员可以进一步将两个支腿21在水平投影上的夹角A进一步优选为18°-30°，将两个支腿21在水平投影上的夹角A具体设置为18°、20°、22°、23°、23.5°、25°、25.5°、26°、28°、30°等，在此不作唯一限定。
在本申请另一实施例中，请参照图2，螺接孔301至少有两个，其中一螺接孔301与螺丝32螺接时，至少一支腿21的水平投影垂直于固定架10的长度方向。
螺接孔301至少有两个，请参照图5，其中一螺接孔301与螺丝32螺接时，至少一支腿21的水平投影平行于固定架10的长度方向。
结合上面分析，在两个支腿21位于中线的两侧且在水平投影上的夹角A较小的情况下，其中一个支腿21平行于固定架10的长度方向时，支撑件20的两个支点具有最大的宽度距离，而具有最大的抗倾覆能力。因此，在对应的位置设置一螺接孔301，以固定该角度位置。同理，在一支腿21垂直于固定架10的长度方向时，支撑件20的两个支点具有最小的宽度距离，而有利于空间受限区域的放置。因此，在对应的位置设置另一螺接孔301，以固定对应角度位置。本领域技术人员可以在这两个螺接孔301之间再设置若干个螺接孔301，以提高多个角度的选择。
本实施例中，请参照图8，螺接孔301有两个，且两个螺接孔301的开孔方向相互垂直。
在本申请另一实施例中，连接柱31与插接孔201螺接。连接柱31与支撑件20之间，通过螺丝32连接的同时通过插接孔201螺接，该设置能够进一步提高连接柱31与支撑件20的连接紧固性。可以理解，在连接柱31与插接孔201螺接的情况下，多个螺接孔301的连线与连接柱31的螺纹绕设方向平行，使得连接柱31与支撑件20转动时，各螺接孔301逐一经过连接孔202并能够与连接孔202正对。
在本申请另一实施例中，插接孔201上下贯通，连接柱31具有上下设置的第一连段和第二连段，螺接孔301开设于第一连段，第二连段设有外螺纹，并能够穿过插接孔201与螺母螺接。连接柱31与支撑件20之间，通过螺丝32连接的同时通过螺母螺接，该设置能够进一步提高连接柱31与支撑件20的连接紧固性。可以理解，在连接柱31穿过插接孔201与螺母螺接的情况下，各螺接孔301在连接柱31的同一径向截面上周向设置，使得连接柱31与支撑件20转动时，各螺接孔301逐一经过连接孔202并能够与连接孔202正对。
在本申请另一实施例中，请参照图7，各支腿21上设有滚轮41。该设置能够提高立式支撑结构移动的便利性。优选的，滚轮41为万向轮。
在本申请另一实施例中，支撑件20在至少一滚轮41处设有用于限制支腿21移动的锁止件42。锁止件42可以通过限制滚轮41转动限制支腿21的移动。
请参照图7，各滚轮41处均设有锁止件42。锁止件42能够相对滚轮41转动而使其下表面具有与地面抵接的支撑位置和偏离地面的避让位置。滚轮41在锁止件42的下表面处于支撑位置时被抬离地面，而在锁止件42的下表面处于避让位置时抵接地面。在锁止件42的下表面抵接地面时，滚轮41被抬离地面，立式支撑结构被锁止件42所承载，在锁止件42的下表面偏离地面时，滚轮41抵接地面，立式支撑结构被滚轮41所承载。
在本申请另一实施例中，请参照图4，连接组件30还包括加固件33，加固件33与支撑可拆卸连接，并用于将支腿21固定在地面上。在安装位置受限的情况下，调整支撑件20与固定架10的角度，而缩短立式支撑结构各支点的宽度尺寸。此时，立式支撑结构的抗倾覆力矩较小。可以通过加设加固件33的方式，将支腿21固定在地面上，而提高立式支撑结构的抗倾覆能力。
请参照图9和图10，加固件33具有第一装配孔302和第二装配孔303，第一装配孔302用于连接支腿21，优选为螺接。支腿21在第一装配孔302的位置对应开设有螺孔203。第二装配孔303用于与地面连接，可以通过膨胀螺丝或化学螺栓与地面固定连接。第一装配孔302和第二装配孔303的连线偏离支腿21与地面的支点。第一装配孔302、第二装配孔303和支腿21的支点形成三角形稳态结构而有利于提高支腿21与地面的连接稳固性。图示结构中，加固件33具有与支腿21侧表面抵接的第一装配面和与地面抵接的第二装配面，第一装配孔302设于第一装配面，第二装配孔303设于第二装配面。第一装配面和第二装配面之间的连接板倾斜设置，以避让滚轮41。本领域技术人员可以根据实际情况设置加固件33的具体结构，只要实现将支腿21固定在地面即可。
以上所述仅为本申请的较佳实施例而已，并不用以限制本申请，凡在本申请的精神和原则之内所作的任何修改、等同替换或改进等，均应包含在本申请的保护范围之内。
