实施例一 本发明的目的是提供一种无需任何工具就可以达到简易快速拼装显示屏 单元, 又能达到高精度拼接效果的快速拼接装置, 并且此种快速拼接装置能 够批量生产, 适应高密度像素且需要经常拆装的显示屏的拼装。 本发明具体实施方式提供的一种显示屏快速拼接装置如图 1 所示, 其设 置在两个显示屏单元 1 (或者显示单元箱体)之间, 用于显示屏单元 1之间的 固定及连接。 该种显示屏快速拼接装置包括可相互锁扣的, 如图 2所示的左 总成和如图 3所示的右总成。 装配后左总成 2和右总成 3分别对应与一个显 示屏单元 1固定连接, 然后操作右总成 3, 使之与左总成 2锁扣, 即可将两个 显示屏单元 1 拼接起来。 当然, 根据显示屏的尺寸及其它具体情况, 两相邻 显示屏之间有可能如图 1 所示, 设置两组显示屏快速拼接装置, 也可以仅设 置一组显示屏快速拼接装置, 还可以设置两组以上的显示屏快速拼接装置。 所述左总成 2的具体结构如图 2所示, 包括: 左座体 21和锁柱 22, 所述 锁柱 22设置在左座体 21上。 左座体 21的具体结构如图 4所示, 其左右两侧
开设有用于连接所述锁柱 22的锁柱孔 212,而前侧则具有 X向左定位面 211, 且在 X向左定位面 211上开设有定位柱孔 213。 当然, 锁柱 22也可以与左座 体 21—体成型, 此时可认为锁柱 22为左座体 21的一部分, 也能达到基本相 同的技术效果, 但是将两者分开更有利于制造。 所述右总成 3的具体结构如图 3和图 5所示, 包括: 右座体 30、扳手 31、 拉钩 32、 导向销 33、 扳手转轴 34、 拉钩转轴 35 (图 3和图 5中未示出, 可 参考图 10和图 11 )、 定位柱 37和定位柱连接轴 38 (图 3和图 5中未示出, 可参考图 10和图 11 )。 所述右座体 30的具体结构如图 6所示,其前侧具有与所述 X向左定位面 211对应的 X向右定位面 300, 且 X向右定位面 300上开设有用于容纳所述 定位柱 37的定位柱容纳孔 303。定位柱容纳孔 303的位置与所述定位柱孔 213 对应。 右座体 30的左右两侧具有侧壁 301, 且侧壁 301上开设有导向槽 302、 扳手转轴孔 304和安全扣转轴孔 305 ;右座体 30底部还开设有多个安装孔 306, 用于通过螺栓与显示屏单元 1固定连接。 如图 7所示, 所述扳手 31的一端具有供操作者施力的手柄 311, 另一端 设有供扳手转轴 34通过的扳手转轴安装孔 315。 如图 10和图 11所示, 扳手 转轴 34通过扳手转轴孔 304和扳手转轴安装孔 315,将扳手 31可转动的安装 至右座体 30两侧壁 301上的扳手转轴孔 304孔处。 所述拉钩 32的一端通过所述拉钩转轴 35与扳手 31可转动连接。 具体而 言, 手柄 311与扳手转轴安装孔 315之间还设置有拉钩转轴孔 316。 拉钩 32 的具体结构如图 8所示, 其一端具有拉钩转轴安装孔 323。如图 10和图 11所 示, 所述拉钩转轴 35通过拉钩转轴孔 316和拉钩转轴安装孔 323, 将拉钩 32 与扳手 31可转动连接起来。 如图 8所示, 拉钩 32的另一端具有钩子 320, 拉钩 32可通过钩子 320钩 住所述锁柱 22, 从而如图 11所示将左总成 2与右总成 3连接起来。 如图 10和图 11所示, 所述定位柱 37可滑动设置在右座体 30内, 并且 通过所述定位柱连接轴 38与扳手 31可转动及滑动连接。 定位柱 37的具体结
构如图 9所示, 包括: 定位柱体 370, 以及与定位柱体 370后端固定连接的连 接片 371, 实际上连接片 371可以与定位柱体 370—体成型, 也可以通过焊接 与定位柱体 370固定连接成一体。 定位柱体 370前端具有锥面 3701, 起到导 正作用。 连接片 371 上设有腰型孔 3711, 用于通过定位柱连接轴 38与扳手 31连接。 如图 7所示, 扳手 31前端开设有连接片容纳槽 312, 从而在所述连 接片容纳槽 312两侧各形成一个连接壁 313,并且在所述连接壁 313上开设有 用于安装定位柱连接轴 38的定位柱连接轴孔 314。装配后所述定位柱 37即位 于所述定位柱容纳孔 303中, 并可在扳手 31的驱动下在定位柱容纳孔 303内 滑动。 在拉钩 32钩住锁柱 22时, 如图 11所示, 所述定位柱 37伸至左座体 21的所述定位柱孔 213中, 从而对左总成 2与右总成 3在 Y向与 Z向提供定 位。 未锁扣时的状态如图 10所示, 此时可通过所述扳手 31 —端的手柄 311 来扳动所述扳手 31, 使扳手 31绕扳手转轴 34的轴线旋转, 进而可以产生杠 杆效应, 产生更大的力来驱动拉钩 32及定位柱 37运动, 以便拉钩 32的钩子 320钩住左座体 21上的锁柱 22。 同时, 所述定位柱 37伸至左座体 21的所述 定位柱孔 213中, 从而使得左总成 2和右总成 3锁扣, 锁扣后的状态如图 11 所示。 此时, 所述 X向左定位面 211与 X向右定位面 300紧贴, 从而实现左 总成 2与右总成 3在 X向的定位。 或者反方向扳动所述扳手 31, 则拉钩 32 从所述锁柱 22上脱开, 定位柱 37缩回至右座体 30中, 从而使得左总成 2和 右总成 3脱开, 脱开后的状态如图 10所示。 综上所述, 左总成 2与右总成 3锁紧之后, 两者之间在 X向、 Y向、 Z 向都被精确定位, 而左总成 2与右总成 3又分别与两个显示屏单元 1 固定连 接, 所以能实现两个显示屏单元 1 之间的精确定位及可靠连接, 且通过扳手 31可以很方便的操作, 能达到快速拆装的效果。 优选的技术方案中, 所述拉钩 32与右座体 30之间设置有导向结构, 使 得拉钩 32在扳手 31 的驱动下, 能够自行稳定保持一个较好的姿态运动, 以 钩住锁柱 22或者从锁柱 22上脱开。 具体而言, 拉钩 32脱离锁柱 22时, 首 先向左远离锁柱 22运动, 同时有一个抬头的动作, 待拉钩 32完全脱离锁柱
22时, 再向右运动而复位。 在本具体实施方式中, 所述导向结构如图 3和图 5所示, 包括: 设置在 拉钩 32两侧的所述导向销 33 ; 以及如图 6所示, 对应设置在右座体 30两侧 壁 301上的导向槽 302。拉钩 32运动时,所述导向销 33在导向槽 302内滑动, 从而确保拉钩 32的运动姿势。 当然, 拉钩 32的运动姿势主要是指拉钩 32前 端的钩子 320的运动姿势。 如图 8结合图 3、 图 5可知, 拉钩 32的两侧除了 设置有用于供所述拉钩转轴 35通过的拉钩转轴孔 323之外, 还设置有两个导 向销孔 324, 用于设置所述导向销 33。 如图 8所示, 拉钩 32后端中部掏空, 形成避位缺口 322, 避位缺口 322的两侧自然形成连接臂 321。装配后扳手 31 位于所述避位缺口 322内, 而且通过连接臂 321上的拉钩转轴安装孔 323与 所述扳手 3 1可转动连接。 本具体实施方式中具体而言, 导向销 33的结构类似于螺钉, 其一端具有 螺帽, 另一端则具有螺紋。 导向销孔 324 则为与之相适配的螺紋孔, 导向销 33以其具有螺紋的一端旋入所述导向销孔 324中而与所述拉钩 32固定连接。 优选的技术方案中所述右总成 3还包括保险机构 36,所述保险机构 36设 置在右总成 3的运动部件与静止部件之间。 所述保险机构 36在左总成 2与右 总成 3锁扣时, 锁扣住右总成 3的运动部件, 防止左总成 2与右总成 3在外 界因素的作用下脱开, 从而使得锁扣状态更加可靠。 所述运动部件主要指扳 手 3 1、 拉钩 32、 定位柱 37, 以及定位柱连接轴 38、 拉钩转轴 35、 导向销 33 等可以动的零部件。所述静止部件主要指右座体 30, 扳手转轴 34也算静止部 件。 本具体实施方式中具体而言是锁扣住所述扳手 31, 当然, 锁扣住拉钩 32 或是定位柱 37等也能达到基本相同的效果, 但是本具体实施方式中锁扣住扳 手 3 1是最方便的, 其效果也是最好的。 如图 3、 图 5结合图 10 、 图 11可见, 所述保险机构 36在本具体实施方 式中具体而言包括: 安全扣 360、 安全扣复位件 361和安全扣转轴 362。 所述安全扣 360通过安全扣转轴 362可转动的设置在右座体 30的两个安 全扣转轴孔 305处。 安全扣复位件 361在本具体实施方式中为复位弹簧, 其
套设在安全扣转轴 362上, 并弹性作用在安全扣 360与右座体 30之间, 使得 左总成 2与右总成 3处于锁扣状态时, 安全扣 360可以扣住扳手 31, 从而使 得左总成 2与右总成 3可靠锁闭。 安全扣 360 的具体结构如图 12 所示, 其下端设置有安全扣转轴安装孔 3601, 上端具有卡钩 3602。 安全扣 360以所述卡钩 3602扣住扳手 31上的卡 块 317。 卡块 317的具体结构如图 7所示, 其设置在扳手 31中部, 对应安全 扣 360上卡钩 3602的位置。 所述卡钩 3602具有导向斜面 3603, 使得右总成 3与左总成 2进入锁扣状态时, 卡块 317能够以较小的力推开卡钩 3602而进 入保险状态。 进一步优选的技术方案中, 所述卡块 317有两个, 对称设置在扳手 31的 两侧。而卡钩 3602也对应设置有两个; 此种对称的结构, 使得受力更加稳定, 工作更加可靠。 再进一步优选的技术方案中, 所述两个卡钩 3602中的一个, 其上表面延 伸形成具有较大面积按压面 3604的卡钩 3602。需要解除保险状态时, 可用手 指按压所述按压面 3604, 则安全扣 360克服安全扣复位件 361的作用而绕安 全扣转轴 362旋转, 使得卡钩 3602脱离卡块 317, 从而可以很方便的解除保 险状态。 进一步优选的技术方案中如图 10和图 11所示, 所述显示屏快速拼接装 置还包括开启状态保持件 39;所述开启状态保持件 39也设置在右总成 3的运 动部件和静止部件之间, 其能够在拉钩 32未钩住锁柱 22时, 使得右总成 3 保持最大开启状态, 主要是确保定位柱 37完全缩回至右座体 30中, 以免影 响右总成 3靠近左总成 2。待右总成 3随与之固定连接的显示屏单元靠近左总 成 2及相应的显示屏单元, 且所述 X向左定位面 211与 X向右定位面 300对 应贴紧之后, 只需要按压扳手 31上的手柄 311, 即可将两显示屏单元锁扣起 来, 因而操作很是方便。 本具体实施方式中开启状态保持件 39具体而言是一个拉簧, 其被拉伸作 用在定位柱 37与右座体 30之间, 将定位柱 37往右座体 30内拉, 从而确保
在非锁闭状态时定位柱 37不会凸出于 X向右定位面 300。 由于本发明的显示屏快速拼接装置在不用任何工具的情况下, 快捷方便 的实现显示屏之间的互相拼接, 能灵活的适应各种使用场合; 而且其主要零 件, 包括左座体 21、 右座体 30、 拉钩 32、 扳手 31、 安全扣 360等, 均可采 用压铸工艺配合机加工工艺制造, 其制造精度可达到 0.02mm以内。而本发明 结构通过创新, 巧妙转移接触部件的结构设计, 可防止相邻显示屏单元之间 由于挤压而损坏, 可适应高密度像素的显示屏应用。 并通过对拼装接触部件 的精密机械加工、 加工工艺控制, 可达到非常理想的拼装效果, 通常拼装后 的总误差可控制在 0.1mm范围以内, 将拼接精度提高了一个数量级, 从而不 但可以实现快速锁紧, 而且可以实现精确锁固。 实施例二 本具体实施方式提供的显示屏快速拼接装置, 与实施例一的不同之处在 于不具有单独的导向销 33, 而是具有与拉钩 32—体成型的导向柱 325。 采用 压铸工艺制作拉钩 32时, 可以将导向柱 325—起制作出来, 从而减少了零配 件, 而且一体成型的结构更加稳定可靠。 当然, 为了便于装配, 如图 14所示, 在右座体 30上的导向槽 302上缘开设有安装缺口 3021, 装配拉钩 32时, 导 向柱 325直接通过该安装缺口 3021进入导向槽 302,而且因为扳手 31的行程 有限, 装配好后扳动扳手 31, 导向柱 325并不会从导向槽 302内脱出, 从而 不影响功能。 以上内容是结合具体的优选实施方式对本发明所作的进一步详细说明, 不能认定本发明的具体实施只局限于这些说明。 对于本发明所属技术领域的 普通技术人员来说, 在不脱离本发明构思的前提下, 还可以做出若干简单推 演或替换, 都应当视为属于本发明的保护范围。
