一种箱体和包括该箱体的显示屏 技术领域
本发明涉及显示技术领域，更具体地说，它涉及一种箱体和包括该箱体的显示屏。
 背景技术
显示屏在实际使用时，大多数为多个显示屏拼接使用。为保证相邻的显示屏拼接之后能够更好地对齐，一般在显示屏的箱体上设有配套的定位柱和定位孔。但是，目前箱体上的定位柱都是直接固定在箱体上，在拼接之后无法将中间的某一个箱体单独取出维护，使得维护不方便。

 本发明的实施方式
为了使本发明所要解决的技术问题、技术方案及有益效果更加清楚、明白，以下结合附图和实施例，对本发明进行进一步详细说明。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。
本实施例提供了一种显示屏，该显示屏包括显示模组和箱体，显示模组安装在箱体上。箱体包括箱本体1，如图1所述，箱本体1的一侧安装有定位装置，多个显示屏拼接时，定位装置与相邻的箱体上的定位孔配合定位。结合图2所示，定位装置包括定位柱2、弹性件3和联动轴4，定位柱2活动式插接在箱本体1内，定位柱2可做直线运动。弹性件3安装在定位柱2与箱本体1之间，当定位柱2向箱本体1内移动时，弹性件3产生弹性形变。联动轴4转动连接在箱本体1，联动轴4可相对转动，但无法移动。联动轴4与定位柱2联动联接，在本实施例中，联动轴4的两端均露出。显示模组和箱本体1上均开设有与联动轴4对齐的通孔，使得可从正面和背面带动联动轴4转动实现维护。联动轴4的两端均开设有凹槽41，在本实施例中，凹槽41为六角槽，从箱本体1外可借助例如内六角扳手等工具插入凹槽41从而带动联动轴4转动。在其他实施例中，凹槽41也可以为一字槽或其他方形槽，使用的工具与凹槽41对应即可。结合图3和图4所示，定位柱2具有可切换的顶出状态和收起状态，定位柱2的端部顶出在箱本体1外时为顶出状态，定位柱2的端部完全收起在箱本体1外时为收起状态，定位柱2处于收起状态时，弹性件3处于弹性形变状态。当定位柱2处于顶出状态时，借助内六角扳手带动联动轴4转动，联动轴4转动带动定位柱2向箱本体1内移动进而切换至收起状态，弹性件3产生弹性形变；当定位柱2处于收起状态时，借助内六角扳手带动联动轴4转动，联动轴4转动的过程中，弹性件3的弹力驱动定位柱2向箱本体1外移动进而切换至顶出状态。本实施例中的定位装置，联动轴4和定位柱2联动设置，维护工具仅为常见的扳手，且只需要在显示模组上开设一个通孔，借助扳手从正面穿过显示模组即可带动联动轴4转动将定位柱2收起，解除了定位限制，此后即可将箱体拆离，使得维护方便、可靠和快捷。
在本实施例中，如图2所示，联动轴4上设有联动部42，联动部42自联动轴4朝联动轴4的径向延伸而成，联动轴4转动时通过联动部42推动定位柱2向箱本体1内移动。在本实施例中，联动轴4贯穿定位柱2，定位柱2开设有避让空间21，定位柱2移动时，联动轴4在避让空间21内相对移动。在本实施例中，定位柱2开设有联动槽22，当定位柱2处于顶出状态时，联动部42位于联动槽22内，联动轴4转动时通过联动部42抵靠联动槽22内壁从而推动定位柱2向箱本体1内移动。在本实施例中，当定位柱2处于收起状态时，联动部42脱离联动槽22，且联动部42与定位柱2的移动方向平行，使得弹性件3无法驱动定位柱2向箱本体1外移动。在本实施例中，联动轴4的两端与箱本体1之间均设有卡环5，由于卡环5的限制，联动轴4无法沿轴向移动。在本实施例中，箱本体1上开设有避让孔11，安装联动轴4时，联动部42从避让孔11进入。在本实施例中，定位装置还包括盖板6，盖板6通过螺钉7安装在箱本体1上，盖板6位于定位柱2的移动方向上，弹性件3安装在定位柱2与盖板6之间。该定位装置组装在箱本体1上时，先将定位柱2插入，然后将联动轴4插入，联动轴4的联动部42从避让孔11进入，将联动轴4和定位柱2位置匹配好，在联动轴4的两端安装好卡环5，然后将弹性件3套上，最后将盖板6安装固定好。
在本实施例中，弹性件3为压缩弹簧，可以理解的是，在一些其他实施例中，弹性件3也可以替换为其他的弹性部件，使得联动部42位于联动槽22中时，用以驱动定位柱2朝远离盖板6的方向移动，从而实现定位柱2的自动伸出。
以上具体实施例仅仅是对本发明的解释，其并不是对本发明的限制，本领域技术人员在阅读完本说明书后可以根据需要对以上实施例做出没有创造性贡献的修改，但只要在本发明的权利要求范围内都受到专利法的保护。
 工业实用性
本发明的箱体和显示屏，通过设置定位柱、弹性件和联动轴，弹性件安装在定位柱与箱本体之间，联动轴转动连接在箱本体，联动轴与定位柱联动联接；借助维护工具从所述箱本体外可带动联动轴转动，联动轴转动带动定位柱切换顶出状态和收起状态，维护工具仅为常见的扳手，且只需要在显示模组上开设一个通孔，借助扳手从正面穿过显示模组即可带动联动轴转动将定位柱收起，解除了定位限制，此后即可将箱体拆离，使得维护方便、可靠和快捷。因此，具有工业实用性。
