Description

边角保护装置及LED显示屏单元箱体 技术领域
本发明属于电子显示技术领域，更具体地说，是涉及一种边角保护装置及LED显示屏单元箱体。
背景技术
现今广泛应用于舞台、体育馆、会场等各活动现场的大型LED显示屏箱体护角通常由若干边角保护装置拼装组成。在搬运及安装LED显示屏单元箱体的过程中，LED显示屏单元箱体的四角极易因碰撞而致使该部位受到损坏，进而影响到LED显示屏的整体显示效果，为了不让LED显示屏单元箱体的四角受到损坏，现阶段的边角保护装置主要以中心轴旋转固定的方式将护角固定在LED显示屏单元箱体上，但是这种方案的护角在覆盖LED显示屏单元箱体的顶部的两侧壁起保护作用时，没有限位固定机构，很容易让护角又转回来，因而起不到很好的保护作用。
而且在搬运LED显示屏单元箱体的过程中，将LED显示屏单元箱体立起来放置时，LED显示屏单元箱体就会晃动，站立不稳定。
发明内容
本发明的目的之一在于提供一种边角保护装置，以解决现有技术中存在的LED显示屏单元箱体四角容易损坏的技术问题。
为实现上述目的，本发明采用的技术方案是：提供一种边角保护装置，包括滑轨轴、护角卡位机构和护角，所述滑轨轴固定在LED显示屏单元箱体上，所述护角卡位机构固定在所述LED显示屏单元箱体的顶部的侧壁上，所述护角 滑动连接在所述滑轨轴上，所述护角滑动至所述LED显示屏单元箱体的顶部并覆盖所述LED显示屏单元箱体的顶部的两侧壁及所述护角卡位机构时，所述护角卡位机构能将所述护角固定在所述LED显示屏单元箱体的顶部。
进一步地，还包括滑动件，所述滑轨轴上设有与所述滑动件适配的滑轨，所述滑动件滑设于所述滑轨内，所述护角连接于所述滑动件。
进一步地，所述滑动件包括多个滑动轴，多个所述滑动轴均滑设于所述滑轨内且与所述护角固定连接；

进一步地，所述滑轨的靠近所述LED显示屏单元箱体的顶部的一端较所述滑轨的远离所述LED显示屏单元箱体的顶部的一端到所述LED显示屏单元箱体的外周的距离近；
所述护角位于所述滑轨轴的外周向的一侧，所述滑轨轴的面向所述护角的一侧的靠近所述LED显示屏单元箱体的顶部的一端较其远离所述LED显示屏单元箱体的顶部的一端到所述LED显示屏单元箱体的外周的距离近。
进一步地，所述滑轨轴的远离所述LED显示屏单元箱体的顶部的一端设有弹性伸缩件，所述护角滑动至所述滑轨轴的远离所述LED显示屏单元箱体的顶部的一端时，所述弹性伸缩件能将所述护角固定在所述滑轨轴的远离所述LED显示屏单元箱体的顶部的一端。
进一步地，所述护角卡位机构包括弹性卡键，所述LED显示屏单元箱体的顶部的侧壁上设有卡键孔，所述弹性卡键能收缩至所述卡键孔内或伸出所述卡键孔外，
当所述护角滑动至所述LED显示屏单元箱体的顶部时，所述弹性卡键抵压于所述护角并限制所述护角沿所述滑轨轴滑动。
进一步地，所述弹性卡键上还设有弹性按钮，所述弹性按钮能带动所述弹性卡键收缩至所述卡键孔内或伸出所述卡键孔外，
当所述护角滑动至所述LED显示屏单元箱体的顶部时，所述弹性按钮位于 所述护角外。
进一步地，所述护角上设有卡位孔，所述护角滑动至所述LED显示屏单元箱体的顶部时，所述弹性卡键伸入所述卡位孔内。
进一步地，所述护角卡位机构还包括盖板，所述盖板上设有与所述弹性卡键和所述弹性按钮匹配的通孔，所述弹性卡键和所述弹性按钮均伸出所述通孔外，所述弹性卡键和所述弹性按钮通过所述盖板固定在所述LED显示屏单元箱体上。
本发明提供的边角保护装置的有益效果在于：与现有技术相比，本发明边角保护装置的护角能在滑轨轴上滑动至LED显示屏单元箱体的顶部，将LED显示屏单元箱体的顶部的两侧覆盖保护起来，同时，护角卡位机构能将护角卡固在LED显示屏单元箱体的顶部，提高护角保护LED显示屏单元箱体四角的稳定性。
本发明的目的之二在于提供一种LED显示屏单元箱体，以解决现有技术中存在的LED显示屏单元箱体四角容易损坏的技术问题。
为实现上述目的，本发明采用的技术方案是：提供一种LED显示屏单元箱体，包括前述任意一项技术方案述及的边角保护装置和设于所述LED显示屏单元箱体侧壁上的支撑件，当所述护角固定在所述LED显示屏单元箱体的顶部时，所述支撑件与所述护角能将所述LED显示屏单元箱体共同支撑于支撑平台上。
本发明提供的LED显示屏单元箱体的有益效果在于：与现有技术相比，本发明LED显示屏单元箱体的边角保护装置能有效保护LED显示屏单元箱体的四角，避免LED显示屏单元箱体的四角被磕坏；在将LED显示屏单元箱体立起来时，支撑件的自由端能与起保护作用的护角共同支撑LED显示屏单元箱体，使LED显示屏单元箱体稍微倾斜，提高LED显示屏单元箱体立起来的稳定性。
