请参阅图1至图4，现对本申请提供的LED显示屏防撞装置进行说明。LED显示屏防撞装置，包括箱体1、伸缩旋转机构3、防撞片4和安装于箱体1上的显示模组2；
箱体1的周侧设有安装孔12和用于容纳防撞片4的容纳槽11；
伸缩旋转机构3嵌于安装孔12内，并活动连接于箱体1；
防撞片4与伸缩旋转机构3固定连接；
当伸缩旋转机构3不受沿其伸缩方向上的外力时，伸缩旋转机构3自动使防撞片4在容纳槽11外遮挡显示模组2的周侧；
当伸缩旋转机构3受到沿其缩回箱体1的方向上的外力时，伸缩旋转机构3能自动带动位于容纳槽11外的防撞片4缩回并旋转以嵌于容纳槽11内。
拼接两个箱体1时，伸缩旋转机构3受到沿其缩回箱体1的方向上的外力，伸缩旋转机构3自动带动位于容纳槽11外的防撞片4缩回并旋转以嵌于容纳槽11内；当拆开两个拼接的箱体1时，伸缩旋转机构3不受沿其伸缩方向上的外力，伸缩旋转机构3自动带动位于容纳槽11内的防撞片4伸出并旋转以在容纳槽11外遮挡显示模组2的周侧。
本申请提供的LED显示屏防撞装置，与现有技术相比，箱体1上设有安装孔12，伸缩旋转机构3嵌于安装孔12内，能使其结构更加紧凑；容纳槽11和安装孔12均设于箱体1的周侧，缩短了防撞片4的响应时间，简化了伸缩旋转 机构3的结构；伸缩旋转机构3活动连接于箱体1，避免了伸缩旋转机构3脱离箱体1，从而避免了为防护显示模组2带来不便；防撞片4与伸缩旋转机构3固定连接，使得防撞片4的运动状态与伸缩旋转机构3同步，从而方便通过伸缩旋转机构3带动防撞片4防护显示模组2；在伸缩旋转机构3不受沿其伸缩方向上的外力时，伸缩旋转机构3能自动带动防撞片4在容纳槽11外遮挡显示模组2的周侧，从而将显示模组2保护起来，避免显示模组2损坏；当拼装两个LED显示屏的箱体1时，相互靠近的箱体1会给伸缩旋转机构3一个沿其缩回箱体1的方向上的外力，以将伸缩旋转机构3朝向安装孔12的方向挤压，并通过伸缩旋转机构3自动带动防撞片4转动，直至将防撞片4缩回容纳槽11内，从而避免防撞片4干涉LED显示屏的拼装，以减小相邻两个LED显示屏的拼装缝隙；未拼装时，防撞片4遮挡显示模组2的周侧，拼装时，防撞片4缩回容纳槽11内，整个过程无需用户手动操作，简单方便。
具体地，防撞片4的形状根据实际需求设计。
在一实施例中，请参阅图4，伸缩旋转机构3包括嵌于安装孔12内的弹性机构31，防撞片4固设于弹性机构31上；
弹性机构31能带动防撞片4伸出或缩回容纳槽11，相对于电机、气缸等自动控制的方式带动防撞片4运动，通过弹性机构31的机械运动带动防撞片4伸出或缩回容纳槽11，具有成本低廉，结构简单的特点。
在一实施例中，请参阅图4及图6，弹性机构31包括滑设于安装孔12内的导向轴和嵌于安装孔12内的第一弹性构件312，防撞片4与导向轴固定连接，以使防撞片4与导向轴的运动状态相同，并通过导向轴滑设于安装孔12内，使得安装孔12的孔壁对导向轴的运动起到导向作用，从而保证防撞片4能平稳地伸出或缩回容纳槽11，避免防撞片4在运动过程中歪斜而无法较好地保护显示模组2，或避免防撞片4无法嵌入容纳槽11内；
第一弹性构件312的两端分别与导向轴和安装孔12的孔壁抵接，以利用第一弹性构件312的弹性带动导向轴滑动，简化了结构。
在一实施例中，请参阅图4及图6，导向轴为轴套311；伸缩旋转机构3还包括定位轴32，定位轴32嵌于轴套311内，并与安装孔12的孔壁非转动连接，以保证定位轴32始终位于安装孔12内，避免定位轴32脱离安装孔12。
在一实施例中，请参阅图4及图6，定位轴的外侧或轴套311的内侧设有螺旋上升的两端封闭的滑槽3113，轴套的内侧或定位轴32的外侧相应地设有滑块3221；
滑块3221滑设于滑槽3113内，第一弹性构件312能带动轴套311相对于定位轴32运动，以使滑块3221在滑槽3113内滑动，并且在定位轴32不转动及滑槽3113螺旋上升的情况下，使得轴套311相对于定位轴32转动，从而通过轴套311带动防撞片4转动；滑槽3113的两端封闭，则能保证轴套311不会脱离定位轴32。
在一实施例中，请参阅图4至图6，还包括安装于箱体1上的限位件6；定位轴32的侧面设有限位槽3212，限位件6伸入限位槽3212内，从而通过限位件6将定位轴32限位于安装孔12内，并限制定位轴32转动。
具体地，限位件6为机米螺丝。
在一实施例中，请参阅图4、图5及图7至图11，伸缩旋转机构3设为多个，且分布于箱体1的相对的两侧，以便对显示模组2的不同部位进行防护。
在一实施例中，请参阅图4、图5及图7至图11，位于箱体1一侧的伸缩旋转机构3的定位轴32的露出防撞片4的一端具有凸部，位于箱体1另一侧的伸缩旋转机构3的定位轴32的露出防撞片4的一端具有定位孔3222；
相邻箱体1拼接时，位于一个箱体1上的定位轴32的凸部伸入位于另一个箱体1上的定位轴32的定位孔3222内，以快速对正拼接的两个箱体1，从而提高相邻箱体1的拼接效率；在定位要拼接的两个箱体1时，位于一个箱体1上的定位轴32能最先与另一个箱体1上的定位轴32上的定位孔3222的孔壁抵接，因此定位轴32会受到沿其缩回箱体1的方向上的外力，从而带动防撞片4缩回并转动以嵌于容纳槽11内，从而避免影响两个箱体1的拼接。
在一实施例中，请参阅图3至图5，LED显示屏防撞装置还包括设于安装孔12内的第二弹性构件5，限位槽3212沿定位轴32的轴向延伸，以便限位件6能在限位槽3212内滑动，从而使得定位轴32能在安装孔12内沿定位轴32的轴向运动；
第二弹性构件5的两端分别与定位轴32和安装孔12的孔壁抵接，以利用第二弹性构件5直接带动定位轴32在安装孔12内沿定位轴32的轴向滑动，从而为伸缩旋转机构3定位相邻箱体1提供了活动余量，便于两个箱体1的定位和拼接，避免定位轴32过长，而致使拼装后的两个箱体1之间的缝隙过大。
具体地，第一弹性构件312和第二弹性构件5均为弹簧。
在一实施例中，请参阅图4及图5，定位轴32上设有导向孔3211，第二弹性构件5的一端设于导向孔3211内，以便通过导向孔3211的孔壁限位第二弹性构件5，来导向第二弹性构件5的运动，避免第二弹性构件5歪斜，而影响定位轴32在安装孔12内的伸缩运动。
在一实施例中，请参阅图4至图6，定位轴32具有第一大径段321和第一小径段322；
轴套311抵接第一大径段321的靠近第一小径段322的端壁，以通过第二弹性构件5带动定位轴32沿安装孔12作伸出运动，使得第一大径段321的靠近第一小径段322的端壁带动轴套311沿伸出安装孔12的方向运动，同时第一弹性构件312也会带动轴套311沿伸出安装孔12的方向运动，从而为防撞片4伸出容纳槽11提供了更大的力。
具体地，导向孔3211设于第一大径段321上。
具体地，限位槽3212设于第一大径段321。
在一实施例中，请参阅图4至图6，轴套311具有第二大径段3111和第二小径段3112；
第二小径段3112的外径与第一大径段321的外径相同，以便开设安装孔12，避免第二小径段3112的外径过大而增加了安装孔12的加工成本；
第一弹性构件312套设于第二小径段3112，以便第一弹性构件312与第二大径段3111的靠近第二小径段3112的端壁抵接，提高第一弹性构件312的稳定性，还避免了第二小径段3112的外径过小而增加第一弹性构件312与第二小径段3112的间距。
在一实施例中，请参阅图4至图6，防撞片4固设于第二大径段3111的远离第二小径段3112的端面，以增大防撞片4与轴套311的接触面积，从而方便将防撞片4固定于轴套311上。
具体地，防撞片4通过螺钉固定于第二大径段3111的端面。
具体地，滑槽3113设于第二大径段3111，滑块3221设于第一小径段322。
以上所述仅为本申请的较佳实施例而已，并不用以限制本申请，凡在本申请的精神和原则之内所作的任何修改、等同替换和改进等，均应包含在本申请的保护范围之内。
