一种可快速拉伸的反折叠相机三脚架 技术领域
本发明涉及一种相机三脚架， 特别是涉及一种可快速拉伸的反 （转） 折叠三脚架， 属于 摄影、 摄像器材技术领域。 背景技术
摄影机尤其是数码摄影机在人们日常生活中己经渐渐地普及起来， 利用摄影机可以方便 随时与家人亲友一起将生活中的片段或所感兴趣的事物拍摄下来。 在摄影机的拍摄过程中， 为了保证拍摄出来的相片或影片画面稳定和精确， 经常需要将摄影机固定在脚架上。 现有摄 影脚架产品中，最小型的三脚架折叠后还是不足够小巧便携,而桌上型脚架又不够高不适合外 影,所以大多数小数码相机使用者不使用脚架,而在旅行合照等很多场合有自拍的需求。
目前， 传统三脚架支脚大部分为螺纹锁紧或扮扣式锁紧， 操作繁琐； 且收拢后的三脚架 长度较大， 携带不方便； 而专利 ZL200910145693.2中的支脚锁紧方式为摩擦式， 拉伸方便， 但承载力小， 只能适合小型数码相机的使用。 发明内容
本发明的目的在于克服现有的拍摄脚架存在的缺陷，提供一种可快速拉伸的反折叠脚架， 所需解决的技术问题是使三脚架支脚能快速拉伸， 操作简便， 且三脚架能反转折叠， 减小收 拢长度， 便于随身携带。
本发明的目的及解决技术问题是采用以下技术方案来实现的。 依据本发明提供的一种可 快速拉伸的反折叠三脚架包括：可快速拉伸的支脚组件；使支脚能绕轴心转 180°的主体组件; 支撑云台或照相机的中轴组件； 以及与三脚架配装的云台组件； 所述支脚组件包括： 直径依 次减小且可互相连接的多根管件， 及用于各相邻管件间连接的锁紧装置； 所述主体组件包括: 主体、 绕主体转轴作 180°旋转且连接支脚的支脚座， 以及限制支脚旋转的限位装置。
根据本发明实施例的反折叠相机三脚架， 所述多根管件是由第一管件、 第二管件、 第三 管件、 第四管件、 第五管件和第六管件组成。 相邻管件间设有限位单元孔， 连接装置内设有 限位单元， 在相邻管件的限位单元孔轴心处于同一位置时， 限位单元将自动弹到限位单元孔 内， 达到限位作用。
根据本发明实施例的反折叠相机三脚架， 所述第二管件上装有锁圈， 锁圈上开有槽， 开 口弹圈装于锁圈的槽内； 第一管件末端及第二管件首端位置均钻有孔用于放置拨珠， 拨珠一 端设有弹簧， 及限位第一管件与第二管件在圆周方向运动的管件盖和管件后盖， 拨珠与弹簧 安装在管件盖内； 连接第五管件和第六管件的锁紧装置中还设有控制整支支脚拉伸的开关、 弹簧及弹簧套， 弹簧套镶在第六管件内， 随第六管件移动而移动。
根据本发明实施例的反折叠相机三脚架， 所述主体组件的限位装置包括镶嵌在主体内的 镶件齿、 装于支脚座内的导键夹块、 导键齿、 开关及弹簧,以及连接主体与支脚座的转轴、 支 管座镶件和螺丝。
根据本发明实施例的反折叠相机三脚架， 所述镶件齿镶嵌在本体内， 镶件齿设有两个限 位齿牙， 与之对应的导键齿装于支脚座内， 导键齿下端连接弹簧， 中间开槽且设有一斜面， 槽内连接开关； 所述导键齿设有斜面， 开关设有与导键齿中间槽斜面相对应的斜面。
根据本发明实施例的反折叠相机三脚架， 所述中轴组件包括： 多节管件， 管件连接件， 支撑云台或照相机的托盘及连接螺丝。
根据本发明实施例的反折叠相机三脚架， 所述云台组件包括转盘、 球体、 左、 右夹紧块、 转座以及转盘锁紧装置和球体锁紧装置； 转盘锁紧装置可单独调节转盘松紧而不影响球体的 转动； 球体锁紧装置单独调节球体的松紧而不影响转盘的转动。
通过上述技术方案， 本发明一种可快速拉伸的反折叠三脚架具有以下优点：
1、 支脚可快速拉伸， 支脚拉伸、 收回由一键开关控制， 操作简便。
2、 三脚架可反转 180°收拢， 减小三脚架收拢后长度， 且收拢由一键开关控制。
3、在使用环境的影响下， 在三脚架放置不水平的状态下， 通过调节云台球体能使转盘保 持水平， 从而能使安装在转盘上的照相机保证水平， 再通过转盘锁紧装置， 能使照相机在水 平方向做 360°圆周运动。 附图说明

请参阅图 1、 2、 8、 9所示， 本发明提供的一种可快速拉伸的反折叠相机三脚架， 包括： 可快速拉伸的支脚组件 10，使支脚能绕轴心转 180°的主体组件 20，支撑云台或照相机的中轴 组件 30， 及与三脚架配装的云台组件 40。
该支脚组件 10包括： 直径依次减小且可互相连接的多根管件， 所述多根管件是由第一管 件 11、 第二管件 12、 第三管件 13、 第四管件 14、 第五管件 15及第六管件 16组成； 及用于 各相邻管件间连接的锁紧装置 17、 17 ' 。该第二管件 12上装有锁圈 121，锁圈 121上开有槽， 开口弹圈 122装于锁圈 121的槽内。 该第一管件 11末端及第二管件 12首端位置均钻有孔用 于放置拨珠 171， 拨珠 171—端设有弹簧 172及限位第一管件 11与第二管件 12在圆周方向 运动的管件盖 111和管件后盖 112， 拨珠 171与弹簧 172装在管件盖 111内。
连接第五管件 15和第六管件 16的锁紧装置 17 '中还设有控制整支支脚拉伸的开关 171 '、 弹簧 172' 及弹簧套 173 ' ， 该弹簧套 173 ' 镶在第六管件 16内， 随第六管件 16移动而移动。
该主体组件 20包括： 主体 21、 限制支脚旋转的限位装置 22， 及绕主体转轴 211作 180° 旋转且连接支脚的支脚座 23。 该限位装置 22包括： 镶嵌在主体 21内的镶件齿 222， 装于支 脚座 23内的导键夹块 223、 223 ' 、 导键齿 224、 开关 225及弹簧 226， 及连接主体 21与支 脚座 23的转轴 227、 支管座镶件 228和螺丝 229。
如图 4b所示， 该中轴组件 30包括： 多节管件、 管件连接件、 支撑云台或照相机的托盘 及连接螺丝。
该云台组件 40包括： 包括转盘 41， 球体 42， 左、 右夹紧块 43、 43 ' ， 转座 44， 转盘锁 紧装置 45及球体锁紧装置 46。 该转盘锁紧装置 45可单独调节转盘 41松紧而不影响球体 42 的转动； 该球体锁紧装置 46单独调节球体 42的松紧而不影响转盘 41的转动。该球体锁紧装 置 46包括： 第一锁紧壳体 461、 第二锁紧壳体 462、 锁紧盖 463及锁紧手柄 464。
参照图 3和图 4所示， 本发明的第一管件 11末端和第二管件 12首端均设有一个孔， 在 支脚处于拉开状态时， 拨珠 171在弹簧 172的作用力下， 弹入第一管件 11及第二管件 12的 限位孔内， 拨珠 171—端为球面， 一端为圆柱， 从而圆柱直面限制了第一管件 11和第二管件 12的上下移动； 其他管件间的连接方式与第一管件 11和第二管件 12连接方式相同。
在支脚最末管件位即上述的第六管件 16， 在首端开有通孔， 弹簧套 17 镶嵌在通孔内， 弹簧套 Π 内装有弹簧 172' 和拨珠 173 ' 。 在拉开状态时， 拨珠 173 ' 被弹簧 172' 弹入 第五管件 15与第六管件 16的限位孔内，使整支支脚处于锁紧限位状态。向上推动开关 174'， 开关 174' —侧设有斜面， 开关将拨珠 173 ' 压入弹簧套 17 内， 使第六管件 16的限位状 态消除， 第六管件 16可縮回至第五管件 15内， 第六管件 16縮回时， 首端将第四管件与第五 管件连接装置的拨珠 173 ' 向外挤压， 弹簧 172' 处于压縮状态， 第五管件 15与第四管件 14 之间的限位状态解除， 第五管件 15可縮回到第四管件 14内， 以此类推， 所有管件都可縮回 至如图 3状态。 从而可达到由开关 174' —键操作控制拉伸、 縮回支脚管件的目的。 而且在 第六管件 16不縮回状态下， 可由下而上通过依次拉出管件节数来调节支脚管件的长度， 达到 调节三脚架高度的目的。
参照图 5所示， 镶件齿 222镶嵌在本体 221内， 镶件齿 223设有两个限位齿牙， 与之对 应的导键齿 224装于支脚座 23内， 导键齿 224下端连接弹簧 226， 中间开槽且设有一斜面， 槽内连接开关 225，开关 225设有与导键齿 224中间槽斜面相对应的斜面。向内推压开关 225， 导键齿 224向下运动压縮弹簧 226， 导键齿牙与镶件齿牙的配合松开， 如图 6b所示， 从而支 脚座 23连同支脚可绕转轴 211进行 180°转动， 达到所需限位状态时， 松开开关 225， 导键齿 224将自动弹回， 与镶件齿 222达到限位状态， 达到一键操作的目的； 且在主体 21的 G位置 也设有限位， 能使三脚架反折叠状态时不易松动， 如图 6a所示。
如图 7所示， 球体锁紧装置 46控制球体 42的锁紧， 球体 42上端连接转盘 41。 转盘锁 紧装置 45控制转盘的锁紧。在使用环境影响下而导致三脚架放置不水平状态时， 无需调节三 脚架支脚， 只要根据云台转盘上的水平珠 411调节转盘 41的水平状态， 即可保证装配在转盘 41上的照相机保持水平， 松动转盘锁紧装置 45， 可使照相机在水平位置作 360°圆周运动。
以上所述， 仅是本发明的较佳实施例而已， 并非对本发明作任何形式上的限制， 故凡是 未脱离本发明技术方案内容， 依据本发明的技术实质对以上实施例所作的任何简单修改、 等 同变化与修饰,均仍属于本发明技术方案的范围内。
