Description

模块连接结构及LED显示屏 技术领域
本发明涉及显示屏安装配件技术领域，具体涉及一种模块连接结构及LED显示屏。
背景技术
随着社会的发展，LED显示屏的应用越来越广，由于LED显示屏的应用一般采用大面积屏幕显示，需要将LED显示屏单元箱体一个一个拼装起来，由于以往传统的单元箱体是采用连接片利用螺栓连接锁紧，或者采用简易快速锁连接，拼装时效率低、操作时间长，并且安装时至少需要两个人配合才能完成箱体的安装，无法实现一个人单独操作，安装效率大大减低，在LED显示屏面积大、施工时间短且施工人数有限的情况下，很难满足使用需求。
申请号为201410228846.0的发明专利申请文献公开了一种用于显示屏的组装装置，包括第一支体和与第一支体配合以将相邻两个显示屏单元或者显示屏箱体连接在一起的第二支体，还包括具有锁止状态和解锁状态的锁止机构，通过手柄、主动齿轮和齿条来提供驱动锁止机构的锁紧力，虽然能实现显示屏的组装和拆卸，但是使用时需要在相邻两个显示屏之间安装至少两个该装置，而且由于该装置是直接通过挂钩与钩柱配合进行锁紧，需要人工对两显示屏模块及两显示屏上的该组装装置进行预先定位，一个人无法完成操作，安装效率低，而且相邻的显示屏之间仅仅依靠该组装装置进行连接，该组装装置受力均集中在显示屏的边缘，安装结构不够紧固牢靠。

请参阅图1至图7，模块连接结构包括锁紧部1、配合部2、把手3，所述锁紧部1包括：锁紧部面板11、锁紧部顶板12、锁紧部底板13、吊杆21、旋转片22、滑动板23、拉伸弹簧24、滑动拨片25、螺纹衬套26、锁紧手柄27、压缩弹簧28；
所述锁紧部面板11上开设有条形状且相互平行的手柄转动孔111和拨片滑动孔112；所述锁紧部顶板12和锁紧部底板13设于所述锁紧部面板11的一面且相对设置；所述吊杆21，可活动穿设于所述锁紧部顶板12和锁紧部底板13上，并与所述手柄转动孔111垂直，其一端伸出所述锁紧部顶板12并 径向延伸有条形块211；所述旋转片22固定连接于所述吊杆21中部；所述滑动板23连接所述旋转片22；所述拉伸弹簧24，其一端连接所述滑动板23、另一端固定于所述锁紧部面板11上，处于拉伸状态；所述滑动拨片25设于所述锁紧部面板11的另一面，其通过拨片连接杆251连接所述滑动板23，所述拨片连接杆251穿过所述拨片滑动孔112；所述螺纹衬套26套设于所述吊杆21上且外周设有螺纹段261和非螺纹段262，其非螺纹段261所在的端部与所述旋转片22抵接，所述非螺纹段262开有与所述吊杆轴线平行的条形槽孔263，所述锁紧部面板11上设有限位柱15，所述限位柱15设于所述条形槽孔263内；所述锁紧手柄27，与所述螺纹衬套的螺纹段261螺纹连接，其背离所述旋转片22的一端与所述锁紧部顶板12抵接；所述压缩弹簧28设于所述旋转片22与所述锁紧部底板13之间的吊杆21上，处于压缩状态；
所述配合部2包括配合部底板31，所述配合部底板31与所述锁紧部顶板12平行，其开有定位孔311，所述定位孔311与所述条形块211形状相同；所述把手3连接于所述锁紧部顶板12和配合部底板31之间。
本发明采用一体式设计，将所述锁紧部1和配合部2设于把手3首尾两端，当需要将多个模块连接在一起时，先在每个模块上设置本模块连接结构，再使每一模块的配合部与相邻模块的锁紧部连接固定即可，连接时所述把手方便工人将各模块对齐到位并便于操作，使用方便；而且连接后各模块之间通过多个把手连接在一起，把手与把手之间与模块所在的平面内形成一个整体架构，相对于现有的模块组装结构仅设置于模块的边缘局部位置，若模块之间稍不对齐就容易出现松动，本发明模块连接结构的把手贴合于模块的整个高度上，配合部和锁紧部首尾连接于把手两端，不仅便于定位，而且首尾受力方向一致，稳固牢靠。
本发明通过吊杆21和条形块211对上下相邻的两模块进行连接，当将所述模块连接结构按锁紧部1在上、配合部2在下的方位竖向设置于单个模块上时，相邻的两模块按以下方式进行锁紧：初始状态时，所述条形块211与所述配合部底板31上的定位孔311相垂直，向左拨动滑动拨片25，所述滑动板23克服所述拉伸弹簧24的拉伸力同时向左移动，并同时带动旋转片22转动，进而带动所述吊杆21旋转，当吊杆21旋转90度时，所述条形块211方位与所述定位孔311适配，将条形块211深入定位孔311内，放松滑动拨片25，所述旋转片22在拉伸弹簧24的拉力作用下恢复原位，进而使两模块连 接在一起；当需要拆卸时，也只需拨动滑动拨片25将吊杆21移出就能将两模块分开。操作时，将两模块对齐扶稳，其中的一只手捏于把手处并用拇指波动滑动拨片25，即可完成安装，使得单人即可独立完成安装和拆卸，不仅减轻了劳动强度，还无需使用其他的例如螺丝刀等工具，提升了工作效率，缩短了施工周期，降低了使用成本。
本发明还设有螺纹衬套26和锁紧手柄27对连接在一起的两模块进行进一步锁紧，具体过程为：初始状态时，所述螺纹衬套26上端面在压缩弹簧28的反作用力下与锁紧部顶板13抵接，所述螺纹衬套26外周设有条形槽孔263，可以在所述限位柱15里面滑动，但同时也限制了螺纹衬套26的旋转，旋转所述锁紧手柄27，由于锁紧手柄27无法上下移动，通过螺纹的旋转带动螺纹衬套26向下移动，进而缩短两模块的距离，实现进一步锁紧。由此使得，安装好的两模块还可进行锁紧加固，防止两模块连接面之间出现松动，使安装效果牢固可靠。
进一步地，所述吊杆21包括沿轴线方向依次设置的：粗杆段212、台阶段213、吊杆螺纹段214、细杆段215，所述粗杆段212连接所述条形块211，所述台阶段213的径向截面为正方形，且所述正方形的边长不大于所述粗杆段的直径，所述旋转片22开有与所述台阶段正方形适配的方形孔，所述旋转片22安装于台阶段213，所述吊杆螺纹段214安装有限位螺母29，所述细杆段215穿设于所述锁紧部底板13上。
所述吊杆21设有条形块211的一端向另一端的外径逐渐减小，是便于从锁紧部顶板12穿过安装好其它零部件后再穿设于锁紧部底板13上，所述旋转片22通过方形凸台固定于吊杆上，其两端分别通过粗杆部212和限位螺母29进行轴向固定。
进一步地，所述滑动板23包括平板部231、旋转片连接部232和拨片连接部233，所述旋转片连接部232形成于所述平板部231的一面上，所述旋转片连接部232开有旋转片安装孔234，所述旋转片安装孔234轴线与所述吊杆21平行，所述旋转片22设有旋转片驱动杆221，所述旋转片驱动杆221安装于所述旋转片安装孔234内；所述拨片连接部233包括相对设置的两个并开有拨片安装孔235，两所述拨片连接部之间的平板部231上开有平板通孔，所述拨片连接杆251一端固定于滑动拨片25上、另一端开有连接杆通孔252，所述拨片连接杆开有连接杆通孔的一端穿过所述拨片滑动孔和平板通孔，并 通过穿设于所述拨片安装孔和连接杆通孔的旋转轴钉236连接所述滑动板23。
由此使得，所述滑动板23通过旋转片驱动杆221驱动所述旋转片22旋转，进而带动吊杆21旋转，所述滑动拨片25通过旋转轴钉236连接于滑动板23的一端，所述滑动板23的另一端通过拉伸弹簧24连接于锁紧部面板11的一固定位置，所述拉伸弹簧24、滑动板23、拨片滑动孔112、滑动拨片25位于一条直线上，且所述拨片滑动孔112设于所述吊杆21的一侧，进而实现滑动板23沿拨片滑动孔112的来回滑动。
进一步地，所述滑动板23还包括开口部237，所述开口部237开设于所述平板部231的背离所述拨片连接部233的一端，所述拉伸弹簧24连接于所述旋转片连接部232上，所述开口部237底处靠近所述旋转片连接部232，以供所述拉伸弹簧24拉伸。
所述滑动板23通过开设开口部237来容置拉伸弹簧24，使得锁紧部内的各零件布置结构紧凑，相对于现有的一些模块安装结构占据空间过大体积过大使用不方便，本发明体积小，便于安装使用。
进一步地，所述锁紧部面板11上设有限位螺钉16，用以使所述平板部沿与所述锁紧部面板垂直方向固定，并能沿所述拨片滑动孔112滑动。
所述滑动板23沿其滑动方向的两侧分别安装有两个限位螺钉16，用作滑动板23滑动的滑槽，采用限位螺钉16也是便于将滑动板23安装于锁紧部面板11上。
进一步地，所述拨片滑动孔112的背离所述拉伸弹簧24的一端开有与拨片滑动孔112垂直的卡槽113。
所述卡槽113与拨片滑动孔112连成L形，将吊杆的条形块211插装于定位孔311之前，可以先将拨片连接杆251卡于卡槽113处，方便工作人员安装。所述拨片连接杆251与所述滑动板23之间通过旋转轴钉236连接，从而可以略微的相对旋转，使拨片连接杆251能旋转卡于卡槽113内。
进一步地，所述锁紧部1还包括定位销17，所述定位销17设于所述锁紧部顶板12上，且与所述吊杆21平行；所述配合部2还包括定位销孔312，所述定位销孔312设于所述配合部底板31上，且与所述定位销17适配。
所述定位销17与所述吊杆21配合使用，限制了相邻两模块之间的转动，使两模块的连接更加整齐紧固。
进一步地，所述配合部2还包括配合部面板32、配合部侧板33，所述配 合部面板32连接所述配合部底板31，所述配合部侧板33连接所述配合部面板32和配合部底板31；所述锁紧部1还包括锁紧部侧板14，所述锁紧部侧板14连接所述锁紧部顶板12、锁紧部面板11和锁紧部底板13；所述配合部面板32、配合部底板31、锁紧部顶板12、锁紧部面板11、锁紧部底板13垂直延伸于所述把手3同侧。
本发明安装于矩形的LED模块箱体的箱体框架4上时，不限定地，可以将一个模块连接结构安装于箱体框架4的一边或中部，也可以安装多个本模块连接结构来加固两模块箱体之间的连接。优选地，在箱体框架的左右两边分别固定一个，本发明底部与箱体框架一面贴合连接，上下相邻的两模块箱体连接成一体后，左右两相邻的模块箱体的配合部与锁紧部也分别贴合，使模块箱体水平方向也可整齐定位，再通过将左右相邻的两把手固定在一起，也可实现左右两相邻模块箱体之间的连接。
进一步地，所述把手3包括：
锁扣部，具有一外端面41，所述外端面41与配合部侧板33、锁紧部侧板14位于同一平面，所述锁扣部开有锁扣安装孔42并安装有锁扣43，所述锁扣43一端设有锁扣把手44、另一端径向延伸形成一凸柱45。
由此使得，上下相邻的两模块箱体通过锁紧部1和配合部2的锁紧连接固定在一起，左右相邻的两模块箱体通过锁扣部连接紧固在一起，从而实现整个大LED显示屏的拼装。并且,所述外端面41与所述配合部侧板33、锁紧部侧板14位于同一平面，使得左右相邻两LED箱体模块之间贴合且定位好，使得拼接成的整个大LED显示屏结构稳固性好。
本发明还提出一种LED显示屏，由若干个LED显示屏单元箱体拼装而成，所述LED显示屏单元箱体包括箱体框架，所述箱体框架上设有上述任一项所述的模块连接结构。所述模块连接结构的具体结构参照上述实施例，由于本LED显示屏采用了上述所有实施例的全部技术方案，因此同样具有上述实施例的技术方案所带来的所有有益效果，在此不再一一赘述。
以上所述仅为本发明的优选实施例，并非因此限制本发明的专利范围，凡是在本发明的发明构思下，利用本发明说明书及附图内容所作的等效结构变换，或直接/间接运用在其他相关的技术领域均包括在本发明的专利保护范围内。
