背景技术
[0002] LED显示屏由于出色的显示效果及适用性， 在舞台、 商演、 广告、 会展等行业 得到了广泛应用。 LED显示屏一般由较小的单元屏组成， 当显示面积需求较大 吋， 可能需要几十甚至上百块单元屏拼装在一起使用， 因此需要在显示屏上设 置连接锁。
[0003] 然而现有的显示屏连接锁在锁定的吋候， 通常需要让操作者通过多个单独的操 作动作来完成锁紧连接锁的工作， 例如， 有些锁需要先将一块显示屏上的锁头 推动以卡到另一块显示屏的锁孔里面去， 然后将锁头上的搭扣卡在另一块显示 屏的卡位上， 从而造成了显示屏拼接操作吋的不便。

发明的有益效果
有益效果
[0031] 本发明的有益效果是： 通过设置配合安装的转轴和轴套， 在轴套上设置连接头 将转轴定位在轴套内， 并在转轴上设置第一引导槽和第二引导槽， 在连接头上 插设第一定位柱以定位连接头和第一弓 I导槽， 在轴套上插设第二定位柱以定位 轴套和第二引导槽， 将轴套和连接头通过第三定位柱连接， 这样当将连接头定 位在显示屏框架上吋， 转动轴套后， 由于连接头为固定安装在显示屏框架上， 因此此吋轴套转动吋转轴将不会相对转动， 即轴套转动后将使第二定位柱沿着 第二引导槽移动， 实际产生的效果是轴套相对于转轴旋转而转轴不旋转， 同吋 第一定位柱沿着第一弓 I导槽的弓 I导段移动， 转轴从轴套内伸出而不发生任何角 度的转动， 转轴的锁头伸出后进入邻侧的显示屏框架锁定块的锁孔内， 此吋的 第一定位柱移动到引导段和定位段的衔接处， 第二定位柱移动到了第二弓 I导槽 的末端而无法再移动， 当再次转动轴套一个角度吋， 第一定位柱滑入定位段内 ， 第二定位柱将带动转轴旋转一个角度， 使锁头和锁定块的锁孔之间错位， 锁 头扣在锁定块上， 实现连接两相邻显示屏框架的作用。 在整个锁定的过程中， 操作人员无需对快锁件进行移动或者拨动其他锁扣， 锁头的伸出和解锁只需要 一个操作动作即可完成， 即只需要通过旋转轴套即可一次性完成快锁件与显示 屏框架上的锁定块之间的连接或者分离。 本发明的快锁件相对于现有技术中的 快锁件结构更加简单， 可极大提高安装效率， 使用也更加方便、 省力。 另外， 设置限位块和弹性件， 限位块可以对轴套进行限位而达到锁定轴套的效果， 可 以防止快锁件误解锁。

[0045] 下面详细描述本发明的实施例， 所述实施例的示例在附图中示出， 其中自始至 终相同或类似的标号表示相同或类似的元件或具有相同或类似功能的元件。 下 面通过参考附图描述的实施例是示例性的， 旨在用于解释本发明， 而不能理解 为对本发明的限制。
[0046] 参照图 1至图 11， 本发明提供一种快锁件， 包括： 配合安装的轴套 10和转轴 20 ； 所述转轴 20具有锁定段 201和滑动段 202， 所述锁定段 201位于转轴 20的一端端 部； 所述滑动段 202的外轮廓面上设有用以弓 I导转轴 20移动和锁定的第一弓 I导槽 203、 用以引导转轴 20旋转的第二引导槽 204; 所述转轴 20的锁定段 201处套设有 与轴套 10转动连接的连接头 30; 所述连接头 30上对应于第一引导槽 203的位置处 设有第一定位柱 40， 所述对应于第二引导槽 204的位置处设有第二定位柱 50。
[0047] 在上述实施例中， 通过在转轴 20上设置第一引导槽 203和第二引导槽 204， 并使 轴套 10通过第一定位柱 40和第二定位柱 50的定位， 使轴套 10和相对于转轴 20转 动， 并且设置的连接头 30上的第三引导槽 301与轴套 10的第三定位柱 60定位， 连 接头 30和轴套 10不能分离， 形成了只需要转动轴套 10就可以将转轴 20从轴套 10 内推出， 并在推出后转轴 20旋转以完成快锁件的锁定作用， 使转轴 20与锁定块 9 0的定位以及锁定的整个操作过程只有一个旋转动作， 因此可以完成显示屏之间 的快速连接， 无需过多的安装卡接或者插接等动作， 使安装更加快捷， 并且快 锁件包含的零部件少， 例如只有轴套 10、 转轴 20、 连接头 30、 以及第一定位柱 4 0、 第二定位柱 50、 第三定位柱 60 (均为形状一致尺寸略有区别的定位柱） ， 一 共四大部件就组成了本快锁件， 实现了其整体结构简单， 维护方便， 加工制作 难度低的优点。
[0048] 在一种具体的实施例中， 参考图 2， 所述第一引导槽 203为折弯槽， 所述折弯槽 具有沿转轴 20轴线延伸设置的引导段 2031以及与引导段 2031之间具有夹角的定 位段 2032， 所述第二引导槽 204为绕转轴 20轴线螺旋延伸的螺旋槽。 第一引导槽 203使转轴 20朝轴套 10外伸出以及当轴套 10旋转的吋候， 可以带动转轴 20旋转一 个角度， 第二引导槽 204使轴套 10在转动的吋候沿着转轴 20转动， 而且转轴 20此 吋可以不转动只移动伸出， 尤其是当第一定位柱 40在引导段 2031内移动吋， 而 当第一定位柱 40在定位段 2032内移动吋， 第二定位柱 50将由于轴套 10的转动而 推动转轴 20旋转一个角度。 此外， 也可以是其他角度， 例如锐角状或者钝角状 ， 当引导段 2031和定位段 2032之间的夹角为锐角状或者钝角状吋， 将具有一定 的间隙调整作用， 可以调整转轴 10的锁头 2011和锁定块 90的锁孔 901之间的间隙 ， 从而确定转轴 10锁定的松紧程度。
[0049] 进一步地， 参考图 2和图 3， 所述折弯槽具有沿转轴轴线延伸设置的引导段 2031 以及沿转轴周向延伸设置的定位段 2032， 所述折弯槽整体形状为直角状。 这样 可以使第一定位柱 40的移动更顺畅。
[0050] 在一种具体的实施例中， 参考图 2和图 3， 引导段 2031靠近所述连接头 30的安装 位设置， 所述定位段 2032远离连接头 30的安装位设置， 所述第一定位柱 40的端 部滑动于弓 I导段 2031内吋为锁头 2011解锁， 当所述第一定位柱 40的端部滑动于 定位段 2032内吋为锁头 2011锁定。
[0051] 在一种具体的实施例中， 参考图 2和图 3， 第一定位柱 40沿连接头 30的半径方向 插入并直至所述第一定位柱 40的端部伸入第一弓 I导槽 203内。
[0052] 在一种具体的实施例中， 参考图 2和图 3， 第二定位柱 50沿轴套 10的半径方向插 入所述轴套 10直至所述第二定位柱 50的端部伸入第二弓 I导槽 204内。
[0053] 在一种具体的实施例中， 参考图 4和图 5， 与轴套 10套接位置处的所述连接头 30 上设有第三引导槽 301， 所述轴套 10上设有沿其半径方向设置的第三定位柱 60， 所述第三定位柱 60沿轴套 10的半径方向插入所述轴套 10并直至所述第三定位柱 6 0的端部伸入第三引导槽 301内。
[0054] 具体的， 参考图 4、 图 5和图 6， 第一定位柱 40、 第二定位柱 50、 第三定位柱 60 均为圆柱形的定位销状， 第一定位柱 40为固定在连接头 30上， 其为朝连接头 30 的轴心方向伸出， 同理第二定位柱 50为固定在轴套 10上， 其为朝轴套 10的轴心 方向伸出， 第三定位柱 60为设置在轴套 10与连接头 30相衔接的轴套 10上， 其也 为朝轴套 10的轴心方向伸出， 优选的， 在连接头 30的一端设置突出设置的凸台 3 02， 在凸台 302的外缘面设置一圈环形槽， 该环形槽为第三引导槽 301， 在轴套 1 0的一端上设置台阶孔， 用以与连接头 30的凸台 302对接， 在轴套 10上对应于第 三引导槽 301的位置处设置第三定位柱 60， 使第三定位柱 60刚好插在第三引导槽 301内， 这样可以连接轴套 10和连接头 30， 并且连接头 30和轴套 10之间为转动连 接不可分离。
[0055] 优选的， 所述第一引导槽 203靠近连接头 30设置， 所述第二引导槽 204远离所述 连接头 30设置。 由于第一引导槽 203的作用为将转轴 20移动推出轴套 10， 并且转 轴 20的锁定头为从连接头 30处伸出， 因此需要将第一引导槽 203设置在靠近转轴 20伸出的位置处。
[0056] 参考图 2和图 3， 进一步地， 所述第一引导槽 203和第二引导槽 204均设置为至少 两条。 对应的， 每一第一引导槽 203内设置的第一定位柱 40设置为至少一个， 每 一第二引导槽 204内设置的第二定位柱 50为至少一个， 这样可以便于轴套 10在转 动的过程中保持转动吋的受力平衡， 使转动顺畅。
[0057] 更进一步地， 参考图 2， 所述锁定段 201包括锁头 2011和过渡段 2012， 所述过渡 段 2012用以使锁定段 201与滑动段 202连接， 所述锁头 2011的外径尺寸大于所述 过渡段 2012的外径尺寸， 且所述锁头 2011具有两平行设置的锁定面 2013， 所述 锁定面 2013的延伸方向与转轴 20的轴线平行， 所述锁头 2011的锁定面 2013之间 的尺寸小于所述锁头 2011的最大外径尺寸。 优选的， 锁头 2011可以整体呈圆锥 形， 矩形或其他形状， 其外轮廓尺寸大于过渡段 2012的外径尺寸即可， 在锁头 2 011的上设置的与转轴 20轴线平行的两锁定面 2013， 用以使锁头 2011与显示屏框 架上的锁定块 90连接。
[0058] 参考图 2， 所述锁头 2011的整体呈蘑菇头形状， 所述锁头 2011具有两平行设置 的锁定面 2013， 所述锁定面 2013的延伸方向与转轴 20的轴线平行， 所述锁头 201 1的锁定面 2013之间的尺寸小于所述锁头 2011的最大外径尺寸。 锁头 2011设有两 锁定面 2013， 这样可以是锁头 2011整体呈扁平状， 其用以与显示屏上的锁定块 9 0连接， 锁定块 90上设置扁窄状的锁孔 901， 可以容锁头 2011刚好通过， 这样可 以当转轴 20旋转后， 锁头 2011较大尺寸处将卡在锁孔 901的较小尺寸处上， 锁头 2011将不能与锁定块 90分离， 从而连接两相邻的显示屏， 具体的锁定块 90上的 锁孔 901为与锁头 2011尺寸适配的长条形。
[0059] 参考图 4， 所述锁头 2011朝向滑动段 202的一端面设有一段利于锁紧的倾斜面 20 14， 具体的， 当锁头 2011整体呈蘑菇头形状吋， 该斜面 2014位于蘑菇头形状锁 头 2011的底面， 斜面 2014相对于底面的水平方向倾斜一个角度。 当锁头 2011转 动锁定吋， 斜面 2014与另一显示屏上的锁定块 90配合的吋候， 可以起到斜面 201 4在进入锁孔 901内吋能够由松至紧的卡住锁孔 901， 以达到锁头 2011刚刚插入锁 孔 901的吋候转动顺滑， 当要锁定的吋候可以具有拉紧且缩小锁头和锁孔之间间 隙间隙的目的， 并当转动到位吋锁头 2011的底面将与锁孔 901卡定。
[0060] 在一种具体的实施例中， 参考图 1， 所述轴套 10上设有把手 70。 这样可以方便 转动轴套 10。
[0061] 在一种具体的实施例中， 参考图 1， 所述连接头 30的端部设有固定块 80， 所述 连接头 30通过固定块 80固定安装在显示屏框架上。 为了便于快锁件整体的安装 拆卸， 在连接头 30上设置用于使快锁件与显示屏框架连接的固定块 80。
[0062] 参考图 8至图 10， 在一种具体的实施例中， 所述快锁件还包括位于轴套 10上的 限位结构， 所述限位结构包括与轴套 10铰接的限位块 100、 设置在铰接位处的弹 性件 110以及设置于连接头 30上的限位部 303， 位于轴套 10内的连接头 30上设置 所述限位部 303， 弹性件 110施力使限位块 100的一端抵持所述限位部 303， 以阻 止轴套 10相对于连接头 30转动， 所述限位块 100的另一端外露于所述轴套 10。 具 体的， 所述弹性件 110的一端抵持所述限位块 100， 所述弹性件 110的另一端抵持 所述轴套 10。 所述弹性件 110优选扭簧。
[0063] 可选的， 所述限位部 303位于连接头 30的周壁上， 具体的， 所述限位部 303为设 置在连接头 30的外壁上的平面。 快锁件处于解锁状态吋， 按压限位块 100， 使限 位块 100与限位部 303的平面分离， 此吋使轴套处于可随意转动的状态， 放幵限 位块 100， 限位块通过扭簧的作用回位而使限位块 100与限位部 303的平面接触， 此吋快锁件处于锁定状态， 轴套 10是不能相对于连接头 30转动的。
[0064] 所述限位部 303的数量为一个或多个， 当限位部 303的数量为多个吋， 多个所述 限位部 303间隔设置。 优选限位部 303的数量为两个， 一个限位部 303对应于第一 定位柱 40位于引导段 2031远离定位段 2032的一端的情况， 另一限位部 303对应于 第一定位柱 40位于定位段 2032远离引导段 2031的一端的情况。
[0065] 作为拓展， 所述轴套 10上设有供限位块 100伸入轴套 10内的镂空位， 所述轴套 1 0上还设有具有安装槽的把手 70， 所述把手 70的安装槽与轴套 10的镂空位连通， 所述限位块 100设置在安装槽内且限位块 100的一端从镂空位处伸入轴套 10内以 抵持限位部 303， 限位块 100的外露部分位于所述安装槽区域。
[0066] 在上述实施例中， 把手上的安装槽可以收容限位块 100， 使限位块 100不会过于 外凸， 影响外形美观和结构整体尺寸， 并通过安装槽可以对限位块 100进行位置 限定， 避免限位块 100使用吋随意的移动， 限位块 100的一端伸入轴套 10的镂空 位处， 可以使限位块 100对连接头 30进行锁定， 此吋轴套 10在转动的过程中不会 随意的转动。
[0067] 基于上述的快锁件， 本发明还提供了一种显示屏组合件， 包括显示屏框架和安 装在显示屏框架内的显示屏模组， 所述显示屏框架的一侧边上设有快锁件， 所 述快锁件通过其连接头 30与显示屏框架连接， 设有快锁件的所述显示屏框架的 对侧边上设有锁定块 90， 相邻两组显示屏组合件通过快锁件与锁定块 90连接， 所述快锁件为上述任一项所述的快锁件。
[0068] 在一种具体的实施例中， 所述锁定块 90上设有一用以使锁头 2011穿过的锁孔 90 1， 所述锁孔 901的尺寸与锁头 2011的尺寸相适配。
[0069] 在实际应用过程中， 每一个显示屏的框架上均设有锁定块和快锁件， 锁定块和 快锁件为分别设置在显示屏框架相对的两条侧边上， 当两显示屏拼接吋， 相邻 的两个显示屏侧边上的锁定块和快锁件刚好可以匹配锁定。
[0070] 上述对本发明的相关的功能或者效果的描述， 是指其具有该功能或者效果， 其 有可能还具有其他的功能或者效果， 因此， 不应视为对其进行功能或者效果的 不当限定。
