具体实施方式
下面结合附图对本实用新型作进一步详细说明。
如图1至图11所示，本实用新型揭示一种便于收纳的一体式支架，它包括伸缩杆1、止滑锁定机构2以及多个支撑脚3，止滑锁定机构2套设于伸缩杆1外壁上、并可在伸缩杆1上滑动和锁定。本实施例中的支撑脚3数量为三个，该支撑脚3的数量可根据产品的实际需要进行选择。每个支撑脚3与止滑锁定机构2的底部活动连接，且每个支撑脚3连接有支脚4，支脚4的一端于伸缩杆1的底部铰接、另一端铰接于支撑脚3中部位置。其中，伸缩杆1上开设有与支撑脚3相适配的收纳槽11，即三个支撑脚3可折叠收纳于对应的收纳槽11内。当向下推动止滑锁定机构2时，止滑锁定机构2带动与其连接的三个支撑脚3撑开成支撑结构，并通过止滑锁定机构2锁紧定位在伸缩杆1外壁上。如图2所示，当向上拉动止滑锁定机构2时，止滑锁定机构2能够带动三个支撑脚3折叠收纳于收纳槽11内。
具体地，如图4和图5所示，本实用新型第一实施例的止滑锁定机构2包括膨胀套22以及套设于膨胀套22上的固定套21；膨胀套22呈倒圆锥型结构、该膨胀套22外表面设有外螺纹(图未示)，固定套21内表面设有对应的内螺纹，固定套21与膨胀套22通过螺纹相互配合。值得注意的是，为了方便膨胀套22缩紧挤压在 伸缩杆上，在膨胀套22圆周面上开设有多个让位槽口221，这样能够使膨胀套22在缩紧挤压时提供相应的活动空间，本实施例的膨胀套22开设有三个让位槽口221。进一步地，位于让位槽口221下侧具有向内延伸的安装凸台222，其中，安装凸台22上设有滑块5，滑块5固定安装在安装凸台22上并可在收纳槽11内滑动。
如图5所示，支撑脚3朝向膨胀套22的一端设有万向球头31，万向球头31安装于膨胀套22的让位槽口221内，并且可通过膨胀套22带动其沿着收纳槽11内滑动，进而使得支撑脚3能够完全收纳隐藏在收纳槽11内。当需要撑开支撑时，向下推动止滑锁定机构2，使止滑锁定机构2内的膨胀套22带动与其连接的三个支撑脚3呈撑开状态；并且，通过转动固定套迫使与其螺纹配合的膨胀套挤压在伸缩杆外壁上进而实现锁紧定位功能。当需要折叠收纳时，向上拉动止滑锁定机构2，使止滑锁定机构2内的膨胀套22带动三个支撑脚3能够完全收纳隐藏在伸缩杆1的收纳槽11内。
优选地，如图7和图8所示，本实用新型第二实施例的止滑锁定机构2还包括旋钮组件23。旋钮组件23包括具有螺杆231的旋钮232以及内侧设有内螺纹的螺母233；其中，固定套21呈C型环状结构、且该固定套的两端向外弯折各形成一连接部211，两个连接部211均设有螺纹孔，旋钮232上的螺杆231穿过连接部211的螺纹孔并与螺母233连接。即通过旋转旋钮232，使固定套21两端的连接部211在螺杆231与螺母233的配合下相互夹紧，进而使得膨胀套22挤压在伸缩杆外壁上实现锁紧定位功能。
优选地，如图9至图11所示，本实用新型第三实施例止滑锁定机构2与第一实施例的止滑锁定机构2不同之处在于固定套21和膨胀套22取消了螺纹配合方式。具体地，膨胀套22呈筒状结构、且 该膨胀套22外表面设有渐开线齿轮状外凸起223，固定套21内表面设有对应的内凸起212，膨胀套22上的外凸起223卡接在固定套21的内凸起内；通过转动固定套21，使膨胀套22水平转动并迫使膨胀套22外表面的外凸起223能够向轴中心收紧、挤压在伸缩杆1外壁上实现锁紧定位功能。
优选地，支撑脚3的自由端设有硅胶套(图未示)。
本实用新型设置的三个支撑脚能够完全收纳隐藏在伸缩杆的收纳槽内；并且，操作简单快捷，使用时，向下推动止滑锁定机构使三个支撑脚从伸缩杆上打开，然后通过止滑锁定机构锁紧定位，实现三个支撑脚的撑开支撑状态；收纳时，向上拉动止滑锁定机构，使止滑锁定机构能够带动三个支撑脚折叠收纳于收纳槽内完成收纳状态。本实用新型结构简单紧凑，体积小，携带方便，且操作灵活，省时省力，适合大范围推广及应用。
以上仅为本专利优选实施方式，并非限制本专利范围，凡是利用说明书及附图内容所作的等效结构或等效流程变换，直接或间接运用在其它相关的技术领域，均属于本专利保护范围。
