进一步地， 作为连接件的实施例三， 请参见图 7至图 9， 所述连接座 5c包 括左右相对设置的两个连接块 51a、 51b,分别设于两个所述连接块 51a和 51b相 对的两端部的转动块 52a、 52b，卡套于两个所述转动块 52a和 52b外侧的压块 53、 设置于所述两个转动块 52a和 52b正下方的锁紧块 54以及锁紧螺栓 55 , 所述压 块 53呈倒 U型， 所述两个转动块 52a和 52b前后对称设置且相对的两个端面贴 合以收容于所述压块 53的 U型口内； 所述压块 53顶端中部开有过孔， 所述两 个转动块 52a和 52b贴合端面处分别开有对半且上大下小的过孔， 所述锁紧块 54中部设有螺纹孔，所述锁紧螺栓 55穿过所述压块 53和两个转动块 52a和 52b 的过孔与所述锁紧块 54螺紋啮合； 锁紧螺栓 55与锁紧块 54锁紧后， 压块 53 固定不动，但两个转动块 52a和 52b通过各自的对半且上大下小的过孔相对于锁 紧螺栓 55适当转动。
通过连接件的实施例三可曲线连接显示屏单元， 实现曲面的多功能显示屏。 当需要内弧曲面的多功能显示屏时， 如图 9c和图 9d所示， 事先将连接座 5c的两个转动块 52a和 52b通过各自对半且上大下小的过孔相对于锁紧螺栓 55 向外适当转动， 调整到位后， 旋紧锁紧螺栓 55固定两个转动块 52a和 52b;然后 将连接座 5c的两个连接块 51a和 51b分别套装进相邻的两个框架 21的侧壁 211 的通孔 212中， 最后将扭锁 6分别紧贴两个框架 2侧壁 211的内侧面， 旋转扭 锁 6—定角度 (最好为 90。)锁住显示屏单元 2; 依次连接， 就将显示屏单元呈内 弧曲线连接， 形成内弧曲面的多功能显示屏。
当需要外弧曲面的多功能显示屏时， 如图 9e和图 9f 所示， 事先将连接座 5c的两个转动块 52a和 52b通过各自对半且上大下小的过孔相对于锁紧螺栓 55 向内适当转动， 调整到位后， 旋紧锁紧螺栓 55固定两个转动块 52a和 52b;然后 将连接座 5c的两个连接块 51a和 51b分别套装进相邻的两个框架 21的侧壁 211 的通孔 212中， 最后将扭锁 6分别紧贴两个框架 2侧壁 211的内侧面， 旋转扭 锁 6—定角度 (最好为 90。)锁住显示屏单元 2; 依次连接， 就将显示屏单元呈外 弧曲线连接， 形成外弧曲面的多功能显示屏。
当需要 "S"曲面多功能显示屏时， 如图 9g所示， 事先将连接座 5c的两个转 动块 52a和 52b的一个转动块 52a通过其上大下小的半过孔相对于锁紧螺栓 55 向内适当转动， 另一个转动块 52b通过其上大下小的半过孔相对于锁紧螺栓 55 向外适当转动， 调整到位后， 旋紧锁紧螺栓 55固定两个转动块 52a和 52b;然后 将连接座 5c的两个连接块 51a和 51b分别套装进相邻的两个框架 21的侧壁 211 的通孔 212中 , 最后将扭锁 6分别紧贴两个框架 2侧壁 211的内侧面， 旋转扭 锁 6—定角度 (最好为 90。)锁住显示屏单元 2; 接下来两侧通过内外弧曲线连接 的结合， 就实现 "S"曲面的多功能显示屏。
更佳地， 请参见图 10, 上述实施例一至三所描述到的连接件 3的连接座 5 与扭锁 6连接端面处设置有扭锁自锁结构， 所述扭锁自锁结构包括连接座 5上 与扭锁 6贴合的端面处对称开有两个盲孔 56, 盲孔 56中分别装有弹簧 57 , 弹 簧 57的上端部卡有滚珠 58 ,扭锁 6上与所述连接座 5贴合的端面相应位置处设 有卡槽， 滚珠 58在弹簧 57的压力下部分地顶入卡槽中固定扭锁； 转动扭锁时， 滚珠 58在扭锁面的挤压下进入盲孔中， 当扭锁转动到位后， 滚珠 58又在弹簧 57的压力下顶入卡槽中。 通过此扭锁自锁结构， 防止了扭锁的松动。
更佳地， 所述框架 21侧壁 211的外侧面为向内倾斜的倾斜面。 通过设置的 倾斜面可以更好的实现曲面的多功能显示屏。
更佳地， 请参见图 11所示， 可快捷安装的多功能显示屏还设有固定扣件 7, 所述固定扣件 7的两端部向同一侧边伸出， 固定扣件 7—端设有与调节螺栓 73 连接的螺纹孔 71 , 另一端设有通过连接件 3与显示屏单元 2连接的连接孔 72, 固定扣件 7的中间部分搭挂在钢架 9上； 先将固定扣件 7的连接孔 72通过连接 件 3与可快捷安装的多功能显示屏 1连接， 然后将固定扣件 7搭挂在钢架 9上， 最后通过调节螺栓调整将可快捷安装的多功能显示屏 1装于钢架 9上。
更佳地， 请参见图 12, 可快捷安装的多功能显示屏还设有吊挂组 ,8 , 吊挂 组件 8包括吊梁 82、 至少一个与吊梁 82固定连接的吊环 81， 吊梁 82设有通过 连接件 3与可快捷安装的多功能显示屏 1连接的连接孔 821 ;先将吊挂组件 8的 吊梁 82通过连接件 3与可快捷安装的多功能显示屏 1连接， 然后将吊挂组件 8 和多功能显示屏 1一起通过吊环 81挂于挂钩上。 如图 12b所示， 一般需要不止一个吊挂组件， 通过吊梁连接片 86将吊挂组 件连接起来， 所述吊梁连接片 86设有至少两个圓孔， 吊梁 82两端部的两侧边 设有螺纹柱 822, 吊梁连接片 86通过圓孔挂在两个 挂组件相对端部同一侧边 的螺紋柱 822上， 可以两侧边都挂有吊梁连接片 86, 然后通过螺母 85螺纹连接 在螺纹柱 822上固定。 更佳地， 请参见图 13 , 所述显示屏单元 2的面罩 23在 LED灯体一侧且在
LED灯体处具有至少一层回字形结构 231，且面罩 23在 LED灯体之间设有纵横 交错的凹槽 232。 通过此回字形结构可以提高显示屏的显示对比度， 另外纵横交 错的凹槽可以遮挡 LED灯体的拼接缝隙。
以上所揭露的仅为本发明的优选实施例而已， 当然不能以此来限定本发明 之权利范围， 因此依本发明申请专利范围所作的等同变化， 仍属本发明所涵盖 的范围。
