具体实施方式
实施例：一种横向收纳移动支撑腿结构，包括支架底座1和支撑腿2，至少两个支撑腿2一端能够绕竖直转轴16转动的安装于支架底座1下端表面上，各个支撑腿2另一端形成支撑部，还设有止动连接件，所述止动连接件能够将支撑腿2与支架底座1固定定位，所述各个支撑腿2绕竖直转轴16转动能够伸出支架底座1外侧或完全隐藏于支架底座1正下方空间内。通过支撑腿2绕竖直的转轴转动，使得支撑腿2另一端可以在水平方向伸出到支架底座1外侧，将支撑扭矩增大形成稳定支撑，支撑腿2另一端还可以沿竖直转轴16转动转到支架底座1正下方，支架底座1正下方的空间形成支撑腿2的收纳空间，进而将支撑腿2与支架底座1折叠在一起，减小整体的尺寸，便于收纳、储存和运输，该结构简单，零件少，只需一转就能够轻松实现支架的支撑腿2快速展开或收合，且旋转到指定位置后自动定点卡住使用方便，不易发生故障，折叠后尺寸小，便于减小包装尺寸，降低包装成本。
所述止动连接件包括定位槽3和定位轴4，所述定位槽3与竖直转轴16平行间隔的设于支架底座1下面上或支撑腿2一端上侧面上，定位轴4能够沿竖直方向滑动的安装于支撑腿2 一端或支架底座1上，所述定位轴4能够插入定位槽3内或从定位槽3内拔出。支撑腿2转动到展开支撑位置后，通过定位轴4与定位槽3插接实现支撑腿2与支架底座1的固定定位，定位槽3可以设置一个也可以设置两个或更多个，用于支撑腿2展开支撑状态定位和支撑腿2折叠收合状态定位，上述支撑腿2定位结构简单，操作方便，此外，也可以通过螺丝连接或者通过卡扣扣合定位，此为本领域技术人员根据本专利很容易想到的等同替换结构，属于本专利保护范围。
还设有弹性件5和连接帽6，所述定位轴4能够滑动设定距离的安装于支撑腿2一端或支架底座1上，弹性件5给定位轴4提供保持与定位槽3插接的弹性保持力，连接帽6安装于定位轴4上，连接帽6止档于支撑腿2或支架底座1表面上。通过弹性件5使得定位轴4可以弹性滑动伸缩运动，在受到外力作用时，始终保持朝向定位槽3方向伸出的状态，能够在支撑腿2转动到水平展开状态时，自动插入定位槽3内将支撑腿2与支架底座1插接定位，需要折叠时，只需拉动连接帽6，将定位轴4拔出定位槽3即可，还可以是定位轴4端部通过圆弧面与定位槽3开口侧壁接触，通过用力转动支撑腿2使得定位轴4自动退出定位槽3的方式实现定位轴4与定位槽3脱扣，上述结构简单，操作方便，且能够自动定位，使用安全、稳定。
所述支架底座1下侧面或支撑腿2一端上侧面上还设有一弧形的定位轴滑道7，两个定位槽3的开口分别位于定位轴滑道7延伸方向的两端底面上，定位轴4能够沿定位轴滑道7延伸方向滑动，且定位轴滑道7底面能够紧密接触定位轴4端部使弹性件5蓄力。定位轴4在弹性件5作用下形成弹性结构，其被 向上提起脱离定位槽3后，转动支撑腿2后，定位轴4进入弧形的定位轴滑道7内，支撑腿2以竖直转轴16为圆心旋转时，定位轴4进入定位轴滑道7一端内并沿定位轴滑道7滑动，此时定位轴4受到定位轴滑道7底面的顶起使得弹性件5被压缩蓄力，当支撑腿2达到支架底座1正下方的折叠位置后，定位轴4刚好到达定位轴滑道7另一端，此时定位轴4与位于定位轴滑道7另一端内的定位槽3正对，其在弹性件5弹力作用下进入定位轴滑道7另一端的定位槽3内，此时支撑腿2被固定定位在折叠状态，要使支撑腿2反向转动到达支撑位置时，再向外拉出定位轴4，定位轴4反向滑动并最终进入定位轴滑道7一端的定位槽3内即可，该结构既对定位轴4在支撑腿2转动的同时进行滑动导向，又实现了支撑腿2在展开支撑状态和折叠状态进行定位，避免其自由转动脱离展开状态和折叠状态，该结构保证了支撑腿2展开和折叠的稳定，且结构简单，操作方便。
所述支撑腿2一端或支架底座1上设有定位轴安装孔8，所述定位轴安装孔8为一端内径大于另一端内径的台阶通孔，定位轴4为一端直径大于另一端直径的T形轴，弹性件5为套设于定位轴4直径小的一端外侧的弹簧，所述弹簧两端分别紧抵定位轴4两端之间的台阶面和定位轴安装孔8两端之间形成的台阶面上，定位轴4另一端与连接帽6通过螺纹连接定位。上述结构使得定位轴4形成了沿其轴向弹性伸缩的结构，弹簧隐藏于定位轴安装孔8内，节省空间，且不易发生故障，此外，定位轴4也可以采用气弹簧结构或其它弹性材料制作而成，且连接帽6通过螺纹结构与定位轴4另一端定位，可以调节定位 轴4的长度。
所述定位轴安装孔8另一端形成沉头孔结构，连接帽6形成T形盖状结构，连接帽6直径小的一端恰能够容纳于定位轴安装孔8另一端的沉头内，连接帽6直径大的一端止挡于支撑腿2一端或支架底座1表面上。连接帽6采用T形结构，与定位轴安装孔8另一端的沉头形成导向配合，确保定位轴4沿竖直方向滑动，避免发生倾斜，也可以供弹性件5弹开状态的限位。
所述支架底座1下侧表面面上或支撑腿2一端上侧表面上还设有一段与转轴同心的弧形限位槽9，支撑腿2一端或支架底座1下侧还固定设有一限位凸块10，所述限位凸块10能够滑动的插设于所述弧形限位槽9内，限位凸块10止挡于弧形限位槽9延伸方向两端的侧壁。通过限位凸块10在弧形限位槽9内滑动实现支撑腿2转动角度的限位，当支撑腿2转到水平展开状态时，以及转到收合状态时刚好限位凸块10转到弧形限位槽9的两端处，此时支撑腿2无法继续转动，刚好实现准确定位，避免出现展开后定位轴4未插入定位槽3内，导致展开位置没有固定，或固定失败，导致支架发生倾倒，提高了支架使用安全性。
所述支撑腿2一端上侧表面上形成有凸台结构11，所述凸台结构11内形成第一转轴孔，支架底座1上形成有第二转轴孔，转轴能转动的插设于第一转轴孔和第二转轴孔内，转轴一端形成有径向外扩的头部，转轴另一端形成有螺柱部，所述螺柱部顺序穿过平垫片12和蝶形垫片13后最终与螺母14螺接，所述支撑腿2和支架底座1紧密夹设于平垫片12和转轴一端的头部 之间。
上述结构能确保支撑腿2转动顺畅，不会与支架底座1发生干涉，同时，凸台结构11还增加了支撑腿2一端的强度，使得支撑更稳定。
所述支撑腿2形成一端高度高于另一端高度的倾斜结构，支撑腿2另一端的支撑部为万向轮15，采用万向轮15作为支撑部，便于移动。
支架上安装的电子设备正面一侧为前方，电子设备背面一侧为后方，所述支撑腿2为四个，其中两个展开后位于支架底座1前方，另两个展开后位于支架底座1后方，位于底座前方的两个支撑腿2长度大于位于底座后方的支撑腿2长度，四个支撑腿2折叠时交错排列于支架底座1正下方。
以上所述仅是本实用新型的优选实施方式，但并不用于限制本实用新型，应当指出，对于本技术领域的普通技术人员来说，在不脱离本实用新型技术原理的前提下，还可以做出若干改进和变型，也应视为在本实用新型的保护范围内。
