具体实施方式
为了使本发明所解决的技术问题、技术方案及有益效果更加清楚明白，以下结合附图及实施例，对本发明进行进一步的详细说明。应当理解，此处所描述的具体实施例仅仅用以解释本发明，并不用于限定本发明。
如图7至图12所示，本发明实施例提供的LED显示屏箱体，包括后盖200、电源模块300、LED显示模块400、箱体框架500以及拉紧锁100。所述箱体框架500与LED显示模块400固定连接，所述电源模块300安装在所述后盖200内且位于所述后盖200与箱体框架500之间，所述电源模块300朝向所述LED 显示模块400的一侧设置有排针301，所述LED显示模块400上设置有与所述排针301匹配的排母401，所述箱体框架500上对应所述排母401的位置设置有过孔501，所述排针301可穿过所述过孔501与所述排母401插接。
如图1至图6所示，本发明实施例提供的拉紧锁100，包括基座1、转轴2、垫片3以及旋钮4，所述基座1上设置有滑孔121，所述转轴2的一端与所述旋钮4固定连接，所述转轴2的另一端插入所述滑孔121内，所述垫片3转动连接在所述转轴2上，且所述垫片3与旋钮4之间的距离保持恒定。
转动所述旋钮4可使所述转轴2旋转并沿所述滑孔121的轴向滑动，以使所述垫片3远离或靠近所述基座1。
所述基座1固定连接在所述箱体框架500上，所述垫片3固定连接在所述电源模块300上。
转动所述旋钮4使所述垫片3靠近所述基座1时，所述后盖200向朝向所述LED显示模块400的方向移动，以使所述排针301与所述排母401插接。转动所述旋钮4使所述垫片3远离所述基座1时，所述后盖200向背离所述LED显示模块400的方向移动，以解除所述排针301与所述排母401之间的插接。
本发明实施例提供的拉紧锁100，通过转动所述旋钮4，使所述转轴2旋转并沿所述滑孔121的轴向滑动，从而使所述垫片3远离或靠近所述基座1。当该拉紧锁100应用于LED显示屏箱体的辅助安装时，将基座1与箱体框架500固定连接，垫片3与后盖200固定连接。转动所述旋钮4，当转轴2沿所述滑孔121的轴向向朝向基座1所在方向滑动时，垫片3逐渐靠近所述基座1，垫片3将带动后盖200逐渐靠近箱体框架500，以对后盖200与箱体框架500之间的连接起辅助作用。当转轴2沿所述滑孔121的轴向向背离基座1所在方向滑动时，垫片3逐渐远离所述基座1，垫片3将带动后盖200逐渐远离箱体框架500，以逐渐解除后盖200与箱体框架500之间的连接，使后盖200与箱体框架500彼此分离。本发明实施例提供的拉紧锁100可使LED显示屏箱体的安装及拆卸更加快速便捷，有效提高LED显示屏箱体的安装效率。
在一实施例中，如图2所示，所述转轴2包括小径段21以及大径段22，所述小径段21与所述旋钮4固定连接，所述大径段22插入所述滑孔121内并可沿所述滑孔121的轴向滑动。
所述小径段21与大径段22之间形成有台阶面23，所述垫片3的一侧表面与所述台阶面23相抵，所述垫片3的另一侧表面与所述旋钮4相抵。
当所述转轴2沿所述滑孔121的轴向移动时，由于所述垫片3抵接在所述台阶面23与旋钮4之间，使得所述垫片3将随所述转轴2一同沿所述滑孔121的轴向移动，从而使所述垫片3靠近或远离所述基座1。
在一实施例中，如图2所示，所述旋钮4包括抵接片41以及固定连接在所述抵接片41上的把手42，所述垫片3的另一侧表面与所述抵接片41背离所述把手42的一侧表面相抵。
通过设置所述把手42，以便于转动所述旋钮4。所述抵接片41与所述垫片3抵接的表面为平面，以使所述垫片3与抵接片41之间的抵接更加稳定，以更加平稳地带动所述垫片3移动。
在一实施例中，如图2所示，所述垫片3上设置有第一通孔31，所述垫片3通过所述第一通孔31套设在所述小径段21上，以将所述垫片3转动连接在所述转轴2上，并使所述垫片3与旋钮4之间的距离保持恒定。
在一实施例中，如图2及图4所示，所述旋钮4靠近所述基座1的一侧设置有卡接孔43，所述小径段21卡接在所述卡接孔43内，以将所述转轴2与所述旋钮4固定连接。
在一实施例中，如图2及图4所示，所述小径段21的外侧壁上形成有卡槽211，所述卡接孔43的内侧壁上形成有与所述卡槽211匹配的卡块，以便于将所述小径段21卡接在所述卡接孔43内。
在一实施例中，如图2所示，所述拉紧锁100还包括插销5，所述插销5安装在所述转轴2上。
所述基座1包括基板11以及连接在所述基板11上的基柱12，所述滑孔121 设置在所述基柱12上，所述滑孔121的轴线垂直于所述基板11，所述基柱12的侧壁上设置有与所述滑孔121连通的滑槽122。
所述转轴2转动时可使所述插销5沿所述滑槽122滑动，以使所述转轴2沿所述滑孔121的轴向滑动。
在一实施例中，如图2所示，所述滑槽122倾斜设置于所述基柱12的侧壁上。如图5所示，当转动所述转轴2使所述垫片3逐渐靠近所述基座1时，所述插销5将先由所述滑槽122朝向所述旋钮4的一侧开口滑入所述滑槽122内，转动所述转轴2时，如图6所示，所述插销5将沿所述滑槽122滑至所述滑槽122背离所述旋钮4的一侧，以使所述垫片3逐渐靠近所述基座1，从而带动所述后盖200向所述LED显示模块400移动，将所述排针301与排母401插接，完成LED显示屏箱体的安装。
在一实施例中，如图2所示，所述转轴2上设置有第二通孔221，所述插销5安装在所述第二通孔221内，所述插销5的轴线与所述转轴2的轴线垂直，以便于设置所述滑槽122，并使所述插销5沿所述滑槽122滑动。
在一实施例中，如图2所示，所述拉紧锁100还包括弹珠6，所述弹珠6装在所述旋钮4。所述垫片3朝向所述旋钮4的一侧表面上设置有第一弹珠槽32以及第二弹珠槽33。
转动所述旋钮4使所述垫片3远离所述基座1时，所述弹珠6可由所述第一弹珠槽32滑动至所述第二弹珠槽33。转动所述旋钮4使所述垫片3靠近所述基座1时，所述弹珠6可由所述第二弹珠槽33滑动至所述第一弹珠槽32。
所述弹珠6与垫片3由卡点配合，所述弹珠6选用可挤压的弹性结构，以加强手感，达到辅助锁紧的效果。
在一实施例中，如图2所示，所述弹珠6设置有两个，对应地，所述第一弹珠槽32设置有两个，所述第二弹珠槽33设置有两个，两个所述第一弹珠槽32的中心的中心连线与两个所述第二弹珠槽33的中心的中心连线垂直，以使所述旋钮4旋转90°后即可锁紧，实现LED箱体辅助安装的作用。
为使所述旋钮4旋转90°后即可锁紧，所述滑槽122的设置应保证所述旋钮4在旋转90°时，所述插销5可从所述滑槽122朝向所述旋钮4的一侧开口滑至所述滑槽122背离所述旋钮4的一侧。所述旋钮4沿所述滑孔121的轴向移动的距离应不小于所述排针301的长度，以实现所述排针301与排母401之间的完全插接。
在一实施例中，如图2及图12所示，所述垫片3上设置有固定孔34，所述垫片3通过所述固定孔34与所述后盖200固定连接，所述基座1固定连接在所述箱体框架500上。
