Description

技术领域
本发明涉及一种用于支撑诸如望远镜、照相机、摄像机或探测仪等设备的装置 , 具体涉及一种可连续改变角度多功能脚架。 背景技术
三脚架是一种利用三点定面原理工作的装置， 其主要被应用于支撑测量仪器， 摄影机， 照明器材和实验用器材等设备。 常用三脚架一般是通过伸缩支脚的方式达 到调节支撑高度的效果，从而使其支撑的设备可在一定的高度稳定运行。 随着三脚 架应用范围的不断拓展， 人们对其功能也提出日益严格的要求。 例如， 对于天文望 远镜等观测设备来说， 在观测过程中， 若设备稍有抖动或振动， 则极易导致观测失 败， 同时， 该等观测设备通常还会被用户随身携带， 以便在诸如城市、 乡村、 荒漠 和山区等多种复杂的地理、气候环境内应用， 因此，一个结构简单稳固、操作简便， 能够在各种环境中稳定架设， 且支撑高度可方便调整的三脚架是不可或缺的。但现 有的三脚架不能很好地满足上述需要。
例如中国专利公告号为 CN2724048、公告曰为 2005年 9月 7曰的实用新型专利 提出的可调脚管收展角度的三脚架， 其包括有脚管、 护帽， 连接各脚管与护帽的脚 管接头， 护帽上方的云台， 每个护帽上设有多种张角的卡位， 与护帽铰接的脚管接 头上开有装配槽， 装配槽上通过销钉、扭簧装有一弹性按钮， 按钮在扭簧的作用下 与护帽上的卡位对应卡扣配合， 这样的构造虽然可分级调整每支脚管的展开角度。 但若在地形多变的环境中需要对支脚管的跨度不断进行微调时，则对于该三脚架是 较为困难的。
同样， 如中国公开号为 CN1936690、 公开日为 2007年 3月 28日的发明专利提 出的相机三脚架亦有类似缺陷，其在支腿支管座与三脚架主体间设置的快速调节支 腿张开角度的开合机构虽然可实现支腿间跨度的调整，但这种调整亦是以分级调整 的方式进行的， 调整幅度小， 对于在复杂环境不能适应。 又且该三脚架中采用的跨 度调整装置包含棘爪等诸多精密构件， 这也使得该三脚架成本进一步提高，且出现 故障的几率增大。 发明内容
本发明的目的在于提出一种结构简单紧凑、 操作简便、 支脚跨度可在 0 ~ 180 ° 范围内任意调整，且能够在狭窄空间或不平坦地面等各种环境中快速稳定架设的 可连续改变角度多功能脚架， 以克^ I良现有技术中的不足。
为实现上述发明目的， 本发明采用了如下技术方案：
一种可连续改变角度多功能脚架， 包括连接座和至少三个支脚， 各支脚上端与 连接座活动连接， 其特征在于所述三脚架还包括一调节罩及一支撑件， 调节罩和支 撑件分别设置于连接座上方和下方， 各支脚环绕分布于支撑件周围， 且调节罩与连 接座之间以及连接座与支撑件之间的距离于竖直方向上可调，并可在其中任一位置 相对固定， 同时调节罩下端与支撑件夹持固定各支脚， 从而使各支脚与水平面之间 的夹角可随调节罩、 连接座以及支撑件三者相对位置的变化而得以在 0 ~ 90。 的范 围内任意调整。
具体而言， 所述连接座上部与调节罩内壁螺紋结合， 且该两者之间的螺纹连接 长度可调， 所述支撑件通过一锁定件与连接座连接， 当调节罩、 连接座和支撑件的 位置相对固定后， 调节罩下端与支撑件夹持支脚， 使支脚跨度固定。
所述连接座下端面中心处设置一螺纹盲孔， 所述锁定件为一螺栓件， 螺栓件上 端垂直穿过支撑件中心设置的一通孔与该螺纹盲孔结合， 其下端为手柄。
所述调节罩上端面固定设置一云台连接头。
所迷三脚架中还设置一连接头，该连接头下部设置于连接座上端面设置的一凹 槽内， 上部垂直穿过调节罩上端中心处设置的一通孔， 所述锁定件为一螺栓件， 该 螺栓件上端依次垂直穿过支撑件上设置的一通孔及连接座中心处设置的一通孔与 连接头下端面中心处设置的一螺紋盲孔结合， 螺栓件下端为手柄。
所述支撑件为具有环状横截面的构件。
所述支撑件为碗状件， 其上部周缘处对称开设至少三个可收容支脚的深槽。 所述支撑件上上部周缘处还对称开设至少三个与支脚外壁匹配的浅槽。
所述支撑件为支撑板，其外环处对称开设至少三个可收容支脚的深槽及至少三 个与支脚外壁匹配的浅槽。
所述支脚包括一外管和至少一内管， 外管上端与连接座铰接， 下端为开口端， 内管活动套设于外管内， 内管和外管间设置紧固构件， 该紧固构件包括一螺栓件和 一套管件，螺栓件一端穿过套管件及外管上的螺孔后抵紧内管，另一端为制紧手轮。
该可连续改变角度多功能脚架采用主要由调节罩、支撑件及其锁定件等构件组 配成一种结构简单紧凑，操作方便，且可使支脚跨度在 0 ~ 180° 的范围内任意调整 的三脚架支脚跨度调整机构 ,从而克服了现有技术中常用三脚架支脚跨度调整机构 结构复杂， 操作不便， 且支脚跨度调整幅度小的缺陷。
该可连续改变角度多功能脚架的工作原理为：
假设某一时刻该多功能三脚架处于支脚张开， 且支脚跨度固定的状态， 则： 若需要增大三脚架各支脚之间的跨度， 可在保持连接座位置不变的情况下， 使 调节罩上行， 以增大调节罩与连接座之间的竖直距离， 同时使支撑件上行， 以缩小 支撑件与连接座之间的竖直距离， 支脚在支撑件的推动下， 绕其上端向上转动， 使 支脚跨度逐渐增大， 待支脚跨度达到预期值后， 重新将调节罩、 连接座和支撑件相 对固定， 即可使三脚架以增大后的支脚跨度稳定架设；
反之，若要缩小三脚架各支脚之间的跨度，可在保持连接座位置不变的情况下， 使调节罩下行， 以缩小调节罩与连接座之间的竖直距离， 同时使支撑件下行， 以增 大支撐件与连接座之间的竖直距离， 支脚因自身重力及调节罩的推动作用， 而绕其 上端向下转动， 使支脚跨度逐渐减小， 待支脚跨度达到预期值后， 重新将调节罩、 连接座和支撑件相对固定， 可使三脚架再以减小后的支脚跨度稳定架设。
在实际应用中， 用户可依照上述的操作过程通过调整调节罩、 连接座和支撑件 三者之间的相对位置， 而在 0 ~ 180° 的范围内任意调整三脚架各支脚的跨度。较之 现有技术中的逐级调整三脚架支脚跨度的方式， 本发明更为方便实用。
该可连续改变角度多功能脚架的结构可以为多种。 其中一种较优的方式是， 该 三脚架主要由一连接头、 一连接座、 三个以上的支脚、 一调节罩、 一支撑件及其锁 定件构成， 其中锁定件可以为一螺栓件， 各支脚上端与连接座活动连接， 连接头下 部设置于连接座上端面设置的一凹槽内，上部垂直穿过调节罩上端中心处设置的一 通孔， 连接座上部与调节罩的内壁通过螺纹结合， 螺栓件上端依次垂直穿过支撑件 上设置的一通孔及连接座中心处设置的一通孔与连接头下端面中心处设置的一螺 纹盲孔结合， 螺栓件下端为手柄。 这样的设置方式可仅通过改变调节罩和连接座之 间以及螺栓件与连接头之间的螺紋连接长度， 即可改变调节罩、 连接座和支撑件之 间的相对位置， 进而调整各支脚的跨度， 操作非常便捷。
但更为优化的方式是， 该可连续改变角度多功能脚架可主要由一连接座、 三个 以上的支脚、 一调节罩、 一支撑件及其锁定件构成， 其中锁定件可以为一螺栓件， 各支脚上端与连接座活动连接， 连接座上部与调节罩的内壁通过螺纹结合， 螺栓件 上端垂直穿过支撑件上设置的一通孔与连接座下端面中心处设置的一螺纹盲孔结 合， 螺栓件下端为手柄。 上述调节罩的上端可一体设置一云台连接头或通过其它方 式固定设置一云台连接头。 该三脚架的操作方式与上述三脚架相似， 但结构更为筒 单紧凑， 生产成本更为低廉。
上述的支撑件可选用具有环状横截面结构的构件，如支撑板或具有环形上端面 的碗状件等。 且该等支撑件的周缘处可开设若干可收容支脚的深槽， 当需要将各支 脚收起时， 只需将各支脚跨度调整至最小值， 并使支撑件上的各深槽到达与各支脚 相应的位置， 而后将各支脚嵌合于深槽中， 并以橡皮筋或绳索等固紧即可， 此时三 脚架呈一整体杆状件， 便于携带和收藏。 进一步而言， 该等支撑件的周缘处可设置 若干个与支脚外壁形状配合的浅槽， 这样可使三脚架在工作时， 各支脚与支撑板间 的锁定更为紧固， 而不致出现滑动等故障。
另外，该可连续改变角度多功能脚架中的支脚可主要由一外管和一根以上的内 管构成， 外管上端与连接座铰接， 下端为开口端， 内管活动套设于外管内， 内管和 外管间设置紧固构件。 用户可通过调整内管与外管的相对位置， 从而改变支脚的长 度， 进而改变三脚架的支撑高度。 该等支脚长度可分別调整， 因此较之现有技术中 支脚长度仅可统一调整的三脚架， 可具有更广泛的应用范围。
与现有技术相比， 本发明的有益效果在于： 该可连续改变角度多功能脚架结构 简单紧凑、 体积小、 重量轻、 成本低廉、 操作方便， 支脚跨度可在 0 ~ 180° 范围连 续调整， 且支脚长度可分别调整。 本发明能够在各种复杂环境中快速稳定架设， 适 于为诸如天文望远镜、 摄像机等设备提供稳定的支撑， 以满足用户在进行观测和摄 影等操作时对高度和空间的合理分配， 达到良好的效果。 本发明可被广泛应用于观 测、 摄影和照明等多个领域。 附图说明

实施例 1 如图 1 ~ 3所示， 该可连续改变角度多功能脚架包括一连接头 3、 一 连接座 2、 三个支脚 5、 一调节罩 1、一支撑板 41和一螺栓件 42。 连接头 3上端与 一云台连接。 连接座 2设置在调节罩 1内， 调节罩内壁与连接座上部通过具有一定 长度的螺纹结构结合。 连接座的上部为筒状结构， 其上端开口， 下端中心处设置一 通孔。 支脚上端通过铆钉 6与连接座下部铰接。 支撑板 41设置在各支脚 5之间。 连接头 3、 调节罩 1、 连接座 2和支撑板 41于竖直方向上同轴设置。 调节罩 1上端 中心处设置一螺纹通孔， 连接头 3上部设置与该螺紋通孔配合的螺紋结构， 连接头 下部安装于连接座上部设置的一凹槽内。 连接头 3下端面上设置一螺紋盲孔， 螺栓 件 42上端垂直穿过支撑板 41中心处设置的一通孔与连接头下端结合，其下端为手 柄，支撑构件外周缘处对称开设三个可收容支脚的深槽 12和三个与支脚外壁匹配 的浅槽 411。 当调节罩、 连接座以及支撑板 411三者之间相对固定时， 调节罩 1下 端与支撑板 411夹持固定各支脚 5 , 使各支脚 5跨度保持不变。 通过调整调节罩与 连接座的螺纹连接长度， 以及调整螺栓件 42与连接头 3之间的螺紋连接长度， 可 改变调节罩、连接座和支撑件之间的相对位置，进而可在 0 ~ 180。 的范围内任意调 整各支脚的跨度。
上述支脚 5可包括内管 51和外管 52 , 外管上端与连接座 2较接， 下端为开口 端， 内管上端具有一膨胀部， 该膨胀部直径略小于外管内径， 内管活动套设于外管 内，内管和外管间设置紧固构件 53,该紧固构件包括一螺栓件 531和一套管件 532, 螺栓件 531一端依次穿过套管件和外管上的螺孔，并 4氏紧内管，另一端为制紧手轮。
该可连续改变角度多功能脚架的工作原理为：
假设某一时刻该多功能三脚架处于支脚张开， 且支脚跨度固定的状态， 则： 如图 5所示， 若需要增大三脚架各支脚之间的跨度， 可在保持连接座位置不变 的情况下， 旋动调节罩， 减小调节罩与连接座之间的螺紋连接长度（增大调节罩与 连接座的垂直距离 HI ), 使调节罩上行； 同时旋动螺栓件， 增大螺栓件与连接头的 螺紋连接长度（減小支撑板与连接座的垂直距离 H2 )， 使支撑板上行， 支脚在支撑 件的推动下，绕其上端向上转动，使支脚跨度逐渐增大，待支脚跨度达到预期值后， 重新以螺栓件将支撑板和连接座相对固定，即可使三脚架以增大后的支脚跨度稳定 架设；
反之，若要缩小三脚架各支脚之间的跨度，可在保持连接座位置不变的情况下， 旋动调节罩， 增大调节罩与连接座之间的螺紋连接长度， 使调节罩下行； 同时旋动 螺栓件， 减少螺栓件与连接头的螺紋连接长度， 使支撑板下行， 支脚在支撑件的推 动下， 绕其上端向下转动， 使支脚跨度逐渐减小， 待支脚跨度达到预期值后， 重新 以螺栓件将支撑板和连接座相对固定 , 即可使三脚架以增大后的支脚跨度稳定架 设；
按照上述方式， 用户可仅通过调整调节罩、连接座和支撑件三者之间的相对位 置， 而在 0 ~ 180° 的范围内任意调整三脚架各支脚的跨度。
当需要将各支脚 5收起时，只需旋动螺栓件 42，使支撑板下行到一定位置， 而 后旋转支撑板，使各支脚在自身重力带动下旋转至竖直位置（即支脚与水平面夹角 为 90。 ), 并嵌合到各深槽 412中即可， 然后以橡皮筋或绳索等将各支脚固紧， 此 时三脚架呈一整体杆状件（如图 6 ~ 7所示）， 便于携带和收藏。
当利用该可连续改变角度多功能脚架在各种地理环境下为测绘仪器、天文望远 镜或摄像机等设备提供支撑时， 可适时调整三脚架各支脚的跨度和长度。 以下举例 说明：
当在广场、 观测平台等平坦地面上应用该三脚架时， 可采用较小的支脚跨度， 从而使三脚架具有较高的支撑高度， 并可稳定架设；
当在阶梯上应用该三脚架时， 可采用较大的支脚跨度， 以将一个支脚搁置在较 高层台阶上， 另两个支脚设置在较低层台阶上的方式， 使三脚架可稳定架设；
当崎岖不平的山地上应用该三脚架时， 用户可根据所需观测角度和高度， 选择 各支脚的落点， 而后调整三脚架的跨度， 同时分别调整各支脚的长度， 使三脚架可 稳定设置；
尤其需要说明的是， 该可连续改变角度多功能脚架在狭窄环境中，如小型工作 间、 汽车车厢、 山洞等中应用时， 较之现有的各种三脚架亦具有较大优势。
实施例 2如图 7 ~ 10所示， 该可变跨度多功能三脚架包括一连接座 V、 三个 支脚 5、 一调节罩 Γ、 一碗状支撑件 41， 和一螺栓件 42，。 调节罩上端一体设置一 云台连接头 3，。 连接座设置在调节罩下方， 连接座 2， 与调节罩 1， 内壁通过螺紧 方式结合。 各支脚 5上端通过铆钉与连接座 2， 下部周缘处铰接， 支撑件 41， 设置 在各支脚 5之间。 连接座 2， 下端面中心处竖直设置一螺紋盲孔， 螺栓件上端垂直 穿过支撑板中心处设置的一通孔与该螺纹盲孔结合，其下端为手柄。上述支撑件 41， 上端碗沿沿径向外延， 形成环状结构， 且该环状结构的外环处对称开设三个可收容 支脚的深槽和三个与支脚外壁匹配的浅槽。 上述支脚 5， 包括一外管 52，、 第一内 管 51， 和第二内管 55，， 外管 52， 上端与连接座 2， 铰接， 下端为开口端， 第一内 管 51， 活动套设于外管 52， 内， 其下端为开口端， 第二内管 55， 套设在第一内管 中， 外管、 笫一内管和第二内管之间同实施例 1相似的紧固构件锁定。 该支脚 5' 下端还设置脚管套 54。 当调节罩 1，、 连接座 2， 以及支撑件 41， 三者之间相对固 定时， 调节罩 1， 下端与支撑件 41' 夹持固定各支脚 5， 使各支脚 5跨度保持不变。 通过调整调节罩与连接座的螺纹连接长度， 以及调整螺栓件 42， 与连接座 2， 之间 的螺紋连接长度， 可改变调节罩、 连接座和支撑件之间的相对位置， 进而可在 0 ~ 180° 的范围内任意调整各支脚的跨度（如图 11所示）。 该可变跨度多功能三脚架 的工作原理与实施例 1基本相同。
需要指出的是， 上述调节罩、 连接座和支撑板之间亦可釆用其它定位方式， 例 如， 可采用如实施例 1所述紧固构件 53将调节罩与连接座相对锁定及解锁。 而上 述支撑件亦可采用诸如圆形、 矩形、 三角形、 星形等多种形状的板状件或具有环状 横截面的构件， 其材盾亦可选用金属、 工程塑料等； 同时， 上述支脚可为多根内管 依次套设于外管中的结构， 管型可为方管、 圆管、 三角管等多种， 而其颜色、 材质 等亦可依据用户需求而定。
综述之， 上述实施例仅为说明本发明的技术构思及特点， 其目的在于让熟悉此 项技术的人士能够了解本发明的内容并据以实施，并不能以此限制本发明的保护范 围。 凡根据本发明精神实质所作的等效变化或修饰， 都应涵盖在本发明的保护范围 之内。
