所述移动式支架，支架本体100的上部用于安装设备10，如图1、图2所示，当移动式支架位于固定状态时，可将活动防倾体300滑入固定防倾体200中，并通过翻转机构500将翻转踏板400旋转翻下为踏板支撑状态，进而在防止设备10倾倒的同时翻转踏板400也不会绊脚；如图3所示，当移动式支架位于移动状态时，通过翻转机构500将翻转踏板400旋转为翻起状态，同时将活动防倾体300从滑槽210中滑出，在实现移动的同时，活动防倾体300能够保证具有足够的长度，进而活动防倾体300与固定防倾体200具有足够大的底盘，可有效防止设备10倾倒；翻转机构500包括翻转按钮510和连动组件520，通过操作翻转按钮510，翻转按钮510能够驱动连动组件520进而通过连动组件520自动控制翻转踏板400的旋转，自动化程度较高，操作方便。
所述移动式支架，通过将固定防倾体200与活动防倾体300设置在支架本体100的下部，并相应设置第一脚轮220和第二脚轮310，用于起到移动和防止发生倾倒的作用，通过在固定防倾体200上设置滑槽210，活动防倾体300在滑槽210处与固定防倾体200滑动连接，且在活动防倾体300上设置翻转踏板400，能够兼顾固定和移动两种状态，有效保证该移动式支架位于固定状态时既能防止倾倒又不会绊脚，位于移动状态时既能方便移动又能防止倾倒，结构稳定，设备10不易发生倾倒，且使用时不易绊脚，通过设置翻转机构500，能够方便地控制翻转踏板400的状态转换，操作方便，自动化程度较 高。
本实施例中，所述支架本体100可以为钣金材料，可对设备10进行有效支撑，结构稳固。所述固定防倾体200、活动防倾体300也可以采用钣金材料，结构性能好。所述固定防倾体200可以通过螺栓、焊接等方式固定在支架本体100上，固定可靠。进一步的，所述固定防倾体200为杆状结构或面板状结构，所述活动防倾体300为杆状结构。通过将固定防倾体200设置为杆状结构或面板状结构，结构多样；通过将活动防倾体300设置为杆状结构，活动防倾体300在固定防倾体200上的滑槽210内进行滑动时，操作更加方便，且在不影响防倾性能的基础上更加节省材料，节省生产成本。
所述固定防倾体200位于所述支架本体100的后侧，所述活动防倾体300位于所述支架本体100的前侧，进而，固定防倾体200与活动防倾体300能够相互配合在支架本体100的两侧实现防倾作用，防倾效果好，不会绊脚。本实施例中，所述滑槽210为两个，两个滑槽210分别设置在所述固定防倾体200的左右两侧，所述活动防倾体300对应为两个，平衡效果好，可进一步提高防倾性能。所述第一脚轮220设置在所述固定防倾体200远离活动防倾体300的端部，所述第二脚轮310设置在所述活动防倾体300远离固定防倾体200的端部，进而活动防倾体300与固定防倾体200配合能够具有最大的底盘，防倾效果好。
具体的，所述翻转踏板400可以为多种结构，如其截面可以为“L”型、“Z”型等，其目的是为了实现当其旋转为踏板支撑状态时，高度能够保持的较低，进而不会绊脚。本实施例中，所述翻转踏板400包括连接板410和支撑踏板420，所述连接板410的第一端与所述活动防倾体300的外端转动连接，所述连接板410的第二端与所述支撑踏板420连接，当所述翻转踏板400旋转为踏板支撑状态时，所述支撑踏板420与地面贴合。采用上述结构，连接板410能够连接支撑踏板420与活动防倾体300，实现整个翻转踏板400的旋转翻转，在翻转踏板400旋转为踏板支撑状态时，所述支撑踏板420能够与地面贴合，进而支撑踏板420可保证足够低，既能起到固定支撑作用，又不会绊脚。
具体的，所述翻转按钮可以为踩踏脚架或翻转旋钮等，连动组件也可以根据需要设置为多种结构，其目的是通过操作翻转按钮以驱动连动机构运动，进而带动翻转踏板400翻下或翻起。例如，当翻转按钮为踩踏脚架结构时，可以在每个翻转踏板400的一侧设置均设置脚架与连动组件，采用脚架与连动组件配合实现翻转踏板400的自动翻转；或者，在两块翻转踏板400中部设置脚架，通过一个脚架与连动组件配合实现两块翻转踏板400的同时翻转等等。
为了便于示意，图5、图6中将活动防倾体300隐藏，如图4、图5、图6所示，本实施例中，所述活动防倾体300为中空结构，所述翻转按钮510为旋钮结构，所述翻转按钮510设置在所述活动防倾体300的外端且能够相对于所述活动防倾体300旋转，所述连动组件520包括均设于所述活动防倾体300内部的拨动连杆521、卡紧件522和第一弹簧523，所述拨动连杆521的第一端与所述翻转按钮510连接，所述拨动连杆521的第二端用于拨动所述卡紧件522，所述第一弹簧523的第一端与所述活动防倾体300连接接，所述第一弹簧523的另一端与所述卡紧件522的第一端连接，所述卡紧件522的第二端用于与所述翻转踏板400配合，当所述翻转踏板400位于踏板支撑状态时，所述翻转踏板400与所述卡紧件522的第二端相对应处设有卡紧缺口430。
采用上述结构，当翻转踏板400需要旋转为踏板支撑状态时，如图6所示，可扭动翻转按钮510并按下翻转踏板400，翻转按钮510旋转带动拨动连杆521运动，进而在第一弹簧523的作用力下卡紧件522能够跟随拨动连杆521运动，如图5所示，当翻转踏板翻下后，卡紧件522卡入翻转踏板400上的卡紧缺口430处，即可实现翻转踏板400翻转为踏板支撑状态，且能够锁死翻转踏板400，翻转踏板400状态稳定，可起到有效的防倾效果。本实施例中，可以在活动防倾体300的内部设置挡板，以与第一弹簧523的第一端连接，起到干涉限位作用，以给卡紧件522运动的作用力。
进一步的，所述连动组件520还包括用于使所述翻转踏板400恢复为翻起状态的第二弹簧524，所述活动防倾体300的外端设有旋转轴700，所述翻 转踏板400的第一端套设在所述旋转轴700外侧并能够相对于所述旋转轴700旋转，所述翻转踏板400的第一端设有安装缺口440，所述翻转轴在所述安装缺口440处为外露状态，所述第二弹簧524套设在所述翻转轴的外露轴段上。本实施例中，所述第二弹簧524可以为自身具有弹性回复力的回位弹簧，所述第一弹簧523的一端顶住所述翻转踏板400，另一端顶住所述活动防倾体300。采用上述结构，如图5所示，当翻转踏板400需要旋转为翻起状态时，旋转翻转按钮510以带动拨动连杆521运动，拨动连杆521带动卡件移动弹出卡紧缺口430，如图6所示，在第二弹簧524的作用力下翻转踏板400能够自动翻起，进而实现翻转踏板400的自动翻起，操作方便。
如图7、图8、图9、图10所示，所述移动式支架还包括滑动锁止机构600，所述活动防倾体300为中空结构，所述滑动锁止机构600包括杠杆610和支点杆620，所述杠杆610沿所述活动防倾体300的滑动方向设置且位于所述活动防倾体300内部，所述杠杆610的外端上部设锁定按钮630，所述杠杆610的内端下部设有锁止件640，所述支点杆620在所述杠杆610的中部横穿所述杠杆610，且所述支点杆620的两端分别与所述活动防倾体300的对应侧连接，所述活动防倾体300上与所述锁止件640对应处设有伸出缺口320，所述固定防倾体200上在所述滑槽210的内端与外端分别设有与所述锁止件640匹配的锁止口230，所述锁定按钮630部分伸出所述活动防倾体300外。本实施例中，所述锁止件640可以为锁止柱或锁止块等。
如图10所示，当活动防倾体300位于滑槽210内时，杠杆610内端的锁止件640伸入固定防倾体200内端的锁止口230中，活动防倾体300稳固锁止在滑槽210内；当活动防倾体300需要滑出时，如图7、图11所示，可按动所述锁定按钮630并向外拉，此时，锁定按钮630给杠杆610的外端向下的力，杠杆610能够以支点杆620为支点运动，进而杠杆610的后端向上运动，锁止件640与固定防倾体200上内端的锁止口230脱离，活动防倾体300滑出，当滑出后停止按动锁定按钮630，杠杆610通过重力作用其内端的锁止件640伸入固定防倾体200外端的锁止口230中，进而活动防倾体300能够 稳固锁死；同样的，当需要将活动防倾体300滑入滑槽210内时，通过按动锁定按钮630并向内推动活动防倾杆，即可实现活动防倾体300的滑入和锁止。通过采用上述结构，所述滑动锁止机构600通过杠杆610原理来实现对活动防倾体300的锁止，锁紧可靠，结构简单。
本实施例中，所述滑动锁止机构600还包括用于使所述锁止件640复位为锁止状态的复位弹簧650，所述复位弹簧650设置在所述杠杆610的内端。通过设置复位弹簧650，在弹簧作用力与重力配合下，锁止件640能够快速、可靠的锁入锁止口230中，锁紧可靠。进一步的，所述滑动锁止机构600还包括拉动把手660，所述拉动把手660设置在所述活动防倾体300上，且所述拉动把手660位于所述锁定按钮630靠近所述翻转踏板400的一侧。通过设置拉动把手660，当按动锁定按钮630将活动防倾体300向外滑出或向内滑入时，可拉动或推动所述拉动把手660来实现，操作更加方便。
具体的，所述活动防倾体300在所述滑槽210处与所述固定防倾体200的滑动连接方式可以为多种形式，如可以在滑槽210的下槽面上设置滑轨，在活动防倾体300的下侧面上设置与滑轨匹配的滑道，通过滑道与滑轨配合实现滑动连接；或者，采用类似于抽屉原理实现滑动连接等。如图11所示，本实施例中，所述活动防倾体300的内端设有滚动轴承330，所述滑槽210的外端处的上槽壁和下槽壁的两侧均设有与所述活动防倾体300外边缘匹配的润滑垫片240。采用上述结构，活动防倾体300通过滚动轴承330实现与固定防倾体200的滑动连接，使用寿命长，通过设置润滑垫片240，一方面，能够对活动防倾体300起到限位作用，保证活动防倾体300滑动过程中的稳定性，另一方面，还能够起到润滑效果，提高本实施例的活动防倾体300与固定防倾体200的滑动性能和使用寿命。本实施例中，所述润滑垫片240可以为尼龙润滑材料，润滑效果好。
以上所述实施例的各技术特征可以进行任意的组合，为使描述简洁，未对上述实施例中的各个技术特征所有可能的组合都进行描述，然而，只要这些技术特征的组合不存在矛盾，都应当认为是本说明书记载的范围。
以上所述实施例仅表达了本发明的几种实施方式，其描述较为具体和详细，但并不能因此而理解为对发明专利范围的限制。应当指出的是，对于本领域的普通技术人员来说，在不脱离本发明构思的前提下，还可以做出若干变形和改进，这些都属于本发明的保护范围。因此，本发明专利的保护范围应以所附权利要求为准。
