参见图1至图6，示出了本实施例提供的一种箱体1，该箱体1例如为LED显示屏的箱体1。值得说明的是，在其他实施例中，该箱体1也可以是其他类型或者其他用途的箱体1，本实施例仅作为举例，不作为对箱体1实际结构和实际用途的限制。在本实施例中，该箱体1用于与LED显示模组装配的一面称为正面，另一面称为背面。
如图1、图2、图3和图6所示，该箱体1中安装有齿轮2、移动件3、电源接头4和限位件5。该箱体1的背面壁体开设有贯穿壁体的避让孔11。齿轮2可转动地安装在该箱体1内，更具体地，齿轮2包括齿轮部22和柱形部23，柱形部23从齿轮部22的一端沿轴向延伸，齿轮部22的外径大于柱形部23的外径。柱形部23可以***避让孔11中并与避让孔11可相对转动地配合，柱形部23的端面开设有辅助槽21，辅助槽21的槽壁包括平面壁。辅助工具可以***辅助槽21并与辅助槽21的平面壁抵顶，当转动辅助工具时，在平面壁的作用下，辅助工具可以驱动齿轮2整体转动。在本实施例中，该辅助槽21例如为内六角槽，辅助工具可以选用与内六角槽相匹配的内六角工具，例如内六角扳手。在其他实施例中，辅助槽21例如可以是一字槽、内四角槽、内五角槽或内八角槽等等，辅助工具可以根据辅助槽21的具体形式 选择对应的扳手。
移动件3可滑动地安装在该箱体1内，移动件3可相对该箱体1做直线移动。移动件3的一侧面设有齿条31，齿条31与齿轮2的齿轮部22啮合配合。当辅助工具驱动齿轮2转动时，齿轮部22可以带动齿条31做直线往复移动，从而实现移动件3的直线往复移动。
电源接头4安装在移动件3上。当移动件3做直线往复移动时，电源接头4跟随移动件3移动，以从箱体1伸出而切换到伸出状态，或者缩回到箱体1中而切换到缩回状态。该箱体1的侧壁可以开设有供电源接头4在伸出状态和缩回状态之间切换的开口12。
限位件5安装在该箱体1内。限位件5用于与移动件3配合，以将所述电源接头4保持在伸出状态或者缩回状态，避免电源接头4发生不期望的伸出或者缩回。
本实施例的箱体1，借助辅助工具来带动齿轮2转动，齿轮2的转动可以带动齿条31做直线往复移动，移动件3的直线往复移动可以带动电源接头4移动，使得电源接头4能够从开口12向外移动而切换到伸出状态或从开口12向内移动而切换到缩回状态。当电源接头4移动到位后，限位件5将电源接头4保持在伸出状态或者缩回状态，避免电源接头4发生不期望的缩回或者伸出。电源接头4处于伸出状态时便于进行插接，电源接头4处于缩回状态时，不仅箱体1的整体外观上更加美观，箱体1还能够对缩回的电源接头4起到一定的防护作用，避免电源接头4因外露而容易受到撞击。本申请中实现电源接头4伸缩的结构简单，成本也较低。
如图2和图3所示，在本实施例中，移动件3的一侧面间隔设有两个卡槽35，限位件5可以弹性伸缩地卡入两个卡槽35中，以将电源接头4保持在伸出状态或者缩回状态。更具体地，当限位件5卡入其中一个卡槽35中时对应于电源接头4的伸出状态，当限位件5卡入另一个卡槽35中时对应于电源接头4的缩回状态。在本实施例中，限位件5可以为玻珠螺栓，玻珠螺栓为现有的标准件，成本低，且能很好地与卡槽35配合限位。在其他实施例中，限位件5也可以包括限位球和弹性件，或者可以采用其他类似的配合结构。参见图2，可以在箱体1的壁体开设孔洞102，该孔洞102例如可以是用于安装玻珠螺栓的螺纹孔。在一些实施例中，孔洞102例如可以是盲孔，限位件5的弹性件安装在孔洞102中，限位球位于弹性件和移动件3之间。当电源接头4随着移动件3伸出到位或者缩回到位时，限位球在弹性件的作用下可以自动与卡槽35配合，实现电源接头4的限位。
再来参见图2和图3，在本实施例中，箱体1内可以开设有容纳槽13，移动件3滑动连接在容纳槽13中，孔洞102例如可以开设在容纳槽13中，孔洞102的底壁低于容纳槽13的底壁。在本实施例中，移动件3的至少一个侧面可以设有凸条33，移动件3通过凸条33与容纳 槽13的槽壁接触。凸条33的长度可与其所在的移动件3的侧面的长度基本相等，但凸条33的宽度小于其所在的移动件3的侧面的宽度，这样从而有效地减少移动件3与容纳槽13的接触面积，减小移动过程中的摩擦力。
优选地，参见图2和图3，避让孔11可以是阶梯孔，齿轮部22可以嵌入阶梯孔中，避让孔11的孔壁设置有与容纳槽13相通的缺口(图中未标号)，齿轮部22在缺口处与齿条31啮合配合。优选地，为了避免齿轮2从避让孔11中脱落，在箱体1中还可以安装有盖板7，盖板7盖设在齿轮2的齿轮部22的端部上，并且盖板7可以通过螺钉(图中未示出)安装固定在箱体1的壁体上。
如图2和图6所示，在本实施例中，移动件3上安装有夹持件6，夹持件6可通过螺栓(图中未示出)安装在移动件3上，电源接头4安装在夹持件6上。在本实施例中，夹持件6上开设有卡孔61，电源接头4上设有与卡孔61相适配的卡块41，卡块41卡入卡孔61实现电源接头4和夹持件6的卡接固定。夹持件6大体呈U形，夹持件6的底壁设置有安装孔601，移动件3上设置有定位孔32，螺栓可以穿过安装孔601与定位孔32螺接，从而将夹持件6固定在移动件3上。夹持件6的两个相对的侧壁均设置有卡孔61，卡块41与卡孔61一一对应地设置。在本实施例中，夹持件6安装在移动件3的一端，移动件3的另一端上延伸有隔档部34，盖板7位于夹持件6和隔档部34之间，盖板7可以辅助限制移动件3的移动范围，以便于电源接头4更好地在伸出状态和缩回状态之间移动切换。
本实施例的箱体1，齿轮2的齿轮部22和移动件3的齿条31啮合配合，移动件3可以带动电源接头4做直线往复移动，使得电源接头4相对于箱体1可以伸缩。在需要使用电源接头4时，用户可以使用辅助工具(例如内六角工具)在箱体1的背面***辅助槽21，然后沿一个方向旋转辅助工具，即可驱动齿轮2转动，齿轮2转动带动齿条31移动，移动件3即驱动电源接头4从开口12向外移动伸出，当电源接头4伸出到位后，限位件5与其中一个卡槽35配合限位，盖板7与移动件3上的隔档部34接触，将电源接头4保持在伸出状态。在不需要使用电源接头4时，用户将辅助工具***辅助槽21后，反向旋转辅助工具，即可驱动电源接头4从开口12向内移动缩回，当电源接头4缩回到位后，限位件5与其中另一个卡槽35配合限位，盖板7与电源接头4接触，将电源接头4保持在缩回状态。电源接头4缩回后，箱体1不仅外观上更加美观，同时能够对电源接头4起到一定的防护作用。本申请控制电源接头4进行伸缩的结构简单，成本较低。
以上具体实施例仅仅是结合附图对本申请进行解释，并非对本申请的限制，本领域技术人 员不脱离本申请的范围和实质内所作的任何修改、等同替换和改进，均应在本申请的权利范围之内。
