[0024] 为使本发明实施例的目的、 技术方案和优点更加清楚， 下面将结合本发明实施 例中的附图， 对本发明实施例中的技术方案进行清楚、 完整地描述， 显然， 所 描述的实施例是本发明一部分实施例， 而不是全部的实施例。 基于本发明中的 实施例， 本领域普通技术人员在没有作出创造性劳动前提下所获得的所有其他 实施例， 都属于本发明保护的范围。
[0025] 如图 1-图 3所示， 本实施例投影设备用调节支架， 包括底座 1、 X轴调节平台 2、 Υ轴调节平台 3、 旋转调节平台 4和角度调节平台 5; X轴调节平台 2滑动连接在底 座 1上， Υ轴调节平台 3滑动连接在 X轴调节平台 2上， X轴调节平台 2的滑动方向 与 Υ轴调节平台 3滑动方向垂直， 旋转调节平台 4可转动的连接在 Υ轴调节平台 3上 ， 角度调节平台 5设置有螺柱 51， 螺柱 51垂直于旋转调节平台 4并螺纹连接在旋 转调节平台 4上。
[0026] 具体而言， 本实施例投影设备用调节支架中的底座 1相对于投影设备放置的空 间静止不动； X轴调节平台 2沿 X轴方向水平移动， 在其上的 Υ轴调节平台 3、 旋 转调节平台 4、 角度调节平台 5及投影设备机体均做 X轴方向的水平移动； Υ轴调 节平台 3沿 Υ轴方向水平移动， 旋转调节平台 4、 角度调节平台 5及投影设备机体 均做 Υ轴方向的水平移动； 转动旋转调节平台 4， 带动上层的角度调节平台 5围绕 着垂直于旋转调节平台 4平面的轴旋转， 进而投影设备也围绕着该轴转动； 旋转 角度调节平台 5只会带动上层的投影设备相对应部位垂直移动； 每层结构只对其 上层结构有作用， 而不影响其下层结构， 可以对投影设备分别实现 X轴方向水平 移动、 Υ轴方向水平移动、 垂直于旋转调节平台平面的轴的旋转运动以及针对投 影设备底面不同部位局部的 Ζ轴方向的垂直运动。 其中， 可以根据需要在旋转调 节平台 4上设置多个角度调节平台 5， 例如： 可以设置三个角度调节平台 5， 三个 角度调节平台 5的旋转中心形成等腰三角形， 从而实现调节投影设备的姿态。
[0027] 本实施例投影设备用调节支架， 通过设置 X轴调节平台、 Y轴调节平台和旋转 调节平台， X轴调节平台能够相对于底座进行移动， 而 Y轴调节平台能够相对于 X轴调节平台进行移动， 旋转调节平台能够相对于 Y轴调节台转动， 通过调节 X 轴调节平台可以带动其上部的 Y轴调节平台和旋转调节平台沿 X轴方向移动， 而 通过调节 Y轴调节平台可以带动其上部的旋转调节平台沿 Y轴方向移动并确保 X 轴调节平台不动， 通过调节旋转调节平台可以带动其上部的角度调节平台转动 并并确保 X和 Y轴调节平台不动， 同吋， 调节角度调节平台仅能使得投影设备进 行升降运动， 从而实现在调节单个平台吋， 仅对该平台的上层结构起作用， 而 不对下层结构影响， 从而不必整体挪动设备位置就能实现调节， 尤其是投影设 备镜头相对于投影屏幕进行左右、 前后、 上下的位置调节， 方便用户调节投影 设备的姿态， 提高投影设备用调节支架的操作便利性； 而在调节过程中， 用户 可以仅通过调节各个平台结构以实现对应方向的调节， 相比于整体挪动投影设 备的位置， 实现在不影响其他已调节好的参数的前提下， 可以确保各个方向已 经调节好的位置精度， 避免出现不同方向调节吋相互影响， 提高了投影设备的 调节效率和精度。
[0028] 基于上述技术方案， 可选的， 如图 2、 4-7所示， 底座 1上设置有 X轴导轨 11， X 轴调节平台 2上设置有第一导向块 21， 第一导向块 21上幵设有第一导向孔 211， X 轴导轨 11插在第一导向孔 211中， X轴调节平台 2上螺纹连接有 X轴螺钉 22， X轴 螺钉 22的端部抵靠在底座 1上； X轴调节平台 2上设置有 Y轴导轨 23， Y轴调节平 台 3上设置有第二导向块 31， 第二导向块 31上幵设有第二导向孔 311， Y轴导轨 23 插在第二导向孔 311中， X轴调节平台 2上螺纹连接有 Y轴螺钉 24， Y轴螺钉 24的 端部抵靠在 Y轴调节平台 3上； 第一导向块 21与底座 1之间设置有第一复位弹簧 11 1， 第二导向块 31与 X轴调节平台 2之间设置有第二复位弹簧 231。 具体的， X轴调 节平台 2沿着 X轴导轨 11相对于底座 1进行 X向移动， 而 Y轴调节平台 3沿着 Y轴导 轨 23相对于 X轴调节平台 2进行 Y向移动， 在实际操作过程中， 为了有效的提高移 动的精度， 采用 X轴螺钉 22和 Y轴螺钉 24控制 X轴调节平台 2和 Y轴调节平台 3的移 动距离， 并通过第一复位弹簧 111和第二复位弹簧 231控制 X轴调节平台 2和 Y轴调 节平台 3复位。 而通过在 X轴调节平台 2设置 X轴螺钉 22和 Υ轴螺钉 24进行 X和 Υ方 向的调节， 方便用户进行操作， 进一步的实现调节便利性以及调节精度。 其中 ， 第一复位弹簧 111和第二复位弹簧 231可以为压簧， 第一复位弹簧 111靠近 X轴 螺钉 22， 第二复位弹簧 231靠近 Υ轴螺钉 24; 或者， 第一复位弹簧 111和第二复位 弹簧 231可以为拉簧， 第一复位弹簧 111远离近 X轴螺钉 22， 第二复位弹簧 231远 离 Υ轴螺钉 24。 优选的， 为了方便通过 X轴螺钉 22和 Υ轴螺钉 24驱动 X轴调节平台 2和 Υ轴调节平台 3移动， X轴调节平台 2上的一侧部设置有下翻边结构 221， 下翻 边结构 221上幵设有螺纹通孔， X轴螺钉 22螺纹连接螺纹通孔中， 下翻边结构 221 延伸到底座 1的侧壁处， 使得 X轴螺钉 22的端部能够抵靠在底座 1的侧壁上， 以实 现 X轴调节平台 2的移动。 同样的， Υ轴调节平台 3的下表面设置有挡板 32， Υ轴 螺钉 24抵靠在挡板 32上， 挡板 32将延伸到 Υ轴螺钉 24的端部位置， 使得 Υ轴螺钉 2 4的端部能够抵靠在挡板 32上。
[0029] 进一步的， 旋转调节平台 4通过转轴可转动的连接在 Υ轴调节平台 2上， 或者， 如图 1、 图 7和图 8所示， Υ轴调节平台 3上幵设有圆孔 33， 旋转调节平台 4的下表 面设置有凸起的圆环 41和多个卡爪 42， 圆环 41包围住卡爪 42， 圆环 41抵靠在 Υ轴 调节平台 2上， 卡爪 42卡在圆孔 33的边沿。 具体的， 圆环 41能够支撑旋转调节平 台 4相对于 Υ轴调节平台 2进行旋转， 而卡爪 42卡在圆孔 33的边沿， 可以避免旋转 调节平台 4从 Υ轴调节平台 2上脱落， 确保旋转调节平台 4能够可靠的在 Υ轴调节平 台 2上旋转。 优选的， 旋转调节平台 4上螺纹连接有用于与 Υ轴调节平台 3配合以 限制旋转调节平台 4转动的锁紧螺钉 40， 具体的， 当用户转动旋转调节平台 4到 所需位置后， 拧紧锁紧螺钉 40， 使得锁紧螺钉 40顶靠在 Υ轴调节平台 3， 以实现 锁紧定位旋转调节平台 4固定不动。 另外， 角度调节平台 5上设置有定位凸起 52 ， 定位凸起 52插在投影设备上的定位槽中， 使得投影设备能够牢靠的安放在角 度调节平台 5上。
[0030] 在实际使用过程中， 用户能够根据需要， 独立的调节 X、 Υ、 Ζ轴的移动距离， 以及准确的控制投影设备的转动角度， 具体操作如下：
[0031] 1、 X轴方向水平移动： 沿 X轴导轨 11， 向内旋入 X轴螺钉 22， X轴螺钉 22抵接 到底座 1上， 进而使 X轴调节平台 1压缩第一复位弹簧 111， 实现 X轴调节平台 1的 水平位移。 反之， 向外旋转 X轴螺钉 22， X轴调节平台 2在第一复位弹簧 111的作 用下， 反方向水平移动。 因此， 通过 X轴螺钉 22的旋紧与旋松， 可是实现 X轴调 节平台 1相对于底座 1的 X轴方向的水平移动， 进而实现上层 Y轴调节平台 3、 旋转 调节平台 4和角度调节平台 5的 X轴方向的水平移动， 实现投影设备的 X轴方向的 水平调节。
[0032] 2、 Y轴方向的水平移动： 沿 Y轴导轨 24， 向内旋入 Y轴螺钉 24， Y轴螺钉 24抵 接到 Y轴调节平台 3的挡板 32上， 使 Y轴调节平台 3压缩第二复位弹簧 231， 实现 Y 轴调节平台 3的另一个维度的水平位移。 反之， 向外旋转 Y轴螺钉 24， Y轴调节平 台 3在第二复位弹簧 231的作用下， 反方向水平移动。 因此， 通过 Y轴螺钉 24的旋 紧与旋松， 可是实现 Y轴调节平台 3相对于底座 1的 Y轴方向的水平移动， 进而实 现上层旋转调节平台 4和角度调节平台 5的 Y轴方向的水平移动， 实现投影设备的 Y轴方向的水平调节。 此调节阶段， X轴调节平台 2与底座 1一样， 是静止不动的
[0033] 3、 绕 Z轴的旋转运动： 投影设备通过三个角度调节平台 5上的定位凸起 52安装 在本实施例投影设备用调节支架上， 围绕 Z轴转动投影设备， 可以带动旋转调节 平台 4的转动， 此吋三个角度调节平台 5随旋转调节平台 4一起转动。 当旋转到合 适位置吋， 向下旋入锁紧螺钉 40， 将旋转调节平台 4与 Y轴调节平台 3锁紧， 进而 相对于底座 1固定。
[0034] 4、 Z轴方向的垂直运动： 每个角度调节平台 5可以通过各自的螺纹旋转实现自 己的 Z轴方向的"上升"和"下降"， 进而同吋顺吋针或者同吋逆吋针转动三个角度 调节平台 5， 则可以实现投影设备的在 Z轴方向的"上升"和"下降"。
[0035] 本发明还提供一种投影设备， 该投影设备的表现实体为激光投影电视， 具体包 括投影设备主体和屏幕， 还包括上述投影设备用调节支架； 在使用状态下， 投 影设备主体放置在角度调节平台上。
[0036] 本实施例投影设备， 通过设置 X轴调节平台、 Y轴调节平台和旋转调节平台， X 轴调节平台能够相对于底座进行移动， 而 Y轴调节平台能够相对于 X轴调节平台 进行移动， 旋转调节平台能够相对于 Y轴调节台转动， 通过调节 X轴调节平台可 以带动其上部的 Y轴调节平台和旋转调节平台沿 X轴方向移动， 而通过调节 Υ轴 调节平台可以带动其上部的旋转调节平台沿 Υ轴方向移动并确保 X轴调节平台不 动， 通过调节旋转调节平台可以带动其上部的角度调节平台转动并并确保 X和 Υ 轴调节平台不动， 同吋， 调节角度调节平台仅能使得投影设备进行升降运动， 从而实现在调节单个平台吋， 仅对该平台的上层结构起作用， 而不对下层结构 影响， 从而不必整体挪动设备位置就能实现调节， 尤其是投影设备镜头相对于 投影屏幕进行左右、 前后、 上下的位置调节， 方便用户调节投影设备的姿态， 提高投影设备用调节支架的操作便利性； 而在调节过程中， 用户可以仅通过调 节各个平台结构以实现对应方向的调节， 相比于整体挪动投影设备的位置， 实 现在不影响其他已调节好的参数的前提下， 可以确保各个方向已经调节好的位 置精度， 避免出现不同方向调节吋相互影响， 提高了投影设备的调节效率和精 度。
最后应说明的是： 以上实施例仅用以说明本发明的技术方案， 而非对其限制； 尽管参照前述实施例对本发明进行了详细的说明， 本领域的普通技术人员应当 理解： 其依然可以对前述各实施例所记载的技术方案进行修改， 或者对其中部 分技术特征进行等同替换； 而这些修改或者替换， 并不使相应技术方案的本质 脱离本发明各实施例技术方案的精神和范围。
