[0056] 参见图 3, 滑动座 23, 包括滑设在基座 21内的推板 231和形成在推板 231顶面的 支撑板 232, 推板 231的顶面具有相互垂直的一横向 D1 (图示中的 D1方向) 和一 纵向 D2 (图示中的 D2方向) , 第二连接器 22固定在推板 231上, 支撑板 232与推 板 231垂直且沿横向 D1延伸。 在本实施中, 支撑板 232的数量为两个, 两个推板 2 31在纵向 D2上相间设置, 推板 231于两个支撑板 232之间凸设有固定支架 233, 以 将第二连接器 22固定在推板 231上并随推板 231移动, 需要说明的是, 推板 231的 移动方向与横向 D1平行。
[0057] 把手 24, 其内端以平行于纵向 D2的第一方向 D3 (图示中的 D3方向) 为轴可转 动地安装于基座 21内, 把手 24的外端置于基座 21外侧以供人手把持。
[0058] 固定轴 27, 其以可转动地方式安装于基座 21内, 且沿第一方向 D3延伸。 从图 5 可以看出, 连接板 212上幵设有供固定轴 27穿过的通孔, 固定轴 27安装在两个连 接板 212上并由连接板 212支撑。 把手 24的内端套设在该固定轴 27上, 并可能带 动固定轴 27转动。
[0059] 驱动件 25, 用于在把手 24前后拨动吋推动推板 231前后移动。 从图 4可以看出, 在本实施例中, 驱动件 25包括套设在固定轴 27上的驱动齿轮 251以及与驱动齿轮 251啮合的齿条 252, 驱动齿轮 251以键连接方式不可转动地套设在固定轴 27上 ( 当然也可以一体成型) , 并位于把手 24的一侧。 齿条 252固设在推板 231上并沿 横向 D1延伸, 驱动齿轮 251与齿条 252相啮合, 这样, 在拧动把手 24吋, 可使固 定轴 27转动, 通过驱动齿轮 251与齿条 252的配合, 实现推板 231的前后移动, 在 把手 24向后 (即向第二侧 21b, 远离第一部件 1的方向) 转动吋, 可推动推板 231 向前 (即向第一部件 1) 移动, 并使第二连接器 22伸出基座 21的第一侧 21a与第一 连接器 12接合。
[0060] 当然, 也可以在推板 231的顶面形成与驱动齿轮 251相啮合的齿槽或凸齿, 该齿 槽和凸齿沿横向 D1延伸, 以实现把手 24转动吋推动推板 231前后移动。
[0061] 锁钩 26, 其内端通过一转轴 29可转动地安装于第一侧 21a, 转轴 29沿平行于第 一方向 D3的方向延伸, 锁钩 26的外端为具有与闩销 112相匹配的钩状结构 261。 从图 3至图 5可以看出, 锁钩 26的侧壁上凸设有向外伸出的导引轴 262, 导引轴 26 2亦沿平行于第一方向 D3的方向延伸, 并位于转轴 29与锁钩 26外端之间, 导引轴 262与转轴 29的轴线非重合。 在本实施例中, 锁钩 26的数量为但不局限于两个, 两个锁钩 26与两个支撑板 232—一对应。 在基座 21的第一侧 21a的顶面具有两个安 装孔位 213, 每个安装孔位 213中分别安装有一个锁钩 26, 每个锁钩 26的转轴 29 端部上分别设置有弹性复位件 201, 该弹性复位件 201为套设在导引轴 262上的弹 簧 (当然还可以是弹片) , 弹簧的一端与安装孔位 213的底面抵接, 另一端与导 引轴 262抵接, 这样, 在锁钩 26被压下前, 锁钩 26大致以垂于推板 231顶面的方 式设置在基座 21的第一侧 21a内。
[0062] 各支撑板 232的侧壁上分别幵设有一个导向槽 234, 导向槽 234从支撑板 232的侧 壁中央朝前 (即横向 D1) 至周边延伸。 当把手 24向后拨动吋, 推板 231向前移动 , 推板 231于导向槽 234上方的前侧壁抵顶导引轴 262, 将导引轴 262向前并向下 顶推, 进而使锁钩 26的外端向前且向下翻转。 随着推板 231继续向前移动使导引 轴 262滑入导向槽 234内, 并压紧弹性复位件 201, 此吋导引轴 262的轴线与转轴 2 9的轴线基本在同一平面上, 锁钩 26的外端卡合于锁扣座 11的卡合部 111, 锁钩 2 6大致与顶板 211平行。 在把手 24向前拨动、 推板 231向后移动, 导引轴 262移出 导向槽 234, 弹性复位件 201使锁钩 26向上翻转复位。
[0063] 为便于导引轴 262滑入, 从图 3可以看出, 支撑板 232的前侧壁 (即靠近第一部 件 1的一侧) 具有与导向槽 234连通的导向缺口 235, 该导向缺口 235具有倾斜设 置的导向斜面, 在导向斜面接触导引轴 262后, 将导引轴 262沿斜面下压, 以便 于导引轴 262移入导向槽 234内。
[0064] 参见图 3至图 5, 第二部件 2还包括在把手 24向第二侧 21b转动吋使锁钩 26向第二 侧 21b移动的联动结构, 联动结构包括第一锥齿轮 202、 第二锥齿轮 203以及螺杆 204, 螺杆 204的前端与转轴 29连接。 在本实施例中, 联动结构的数量为但不局 限于两个, 且与两个锁钩 26—一对应。 两个第一锥齿轮 202分别以键连接方式不 可转动地套设在固定轴 27的两端, 并位于连接板 212外侧, 两个第二锥齿轮 203 分别以平行与横向 D1的方向为轴可转动地安装于基座 21内, 每个第一锥齿轮 202 分别与对应的每个第二锥齿轮 203啮合。 每个第二锥齿轮 203的中央具有形成有 一个螺孔, 并分别螺合有一个螺杆 204, 每个螺杆 204的前端分别套接在对应的 转轴 29上。 在把手 24拨动吋, 第一锥齿轮 202随之转动, 第二锥齿轮 203由第一 锥齿轮 202带动转动并使螺杆 204前后移动, 以拉动锁钩 26前后移动。 当把手 24 向后拨动吋, 两个螺杆 204分别在横向 D1上向后移动, 并拉动锁钩 26向后移动, 这样, 在锁钩 26的外端卡合于锁扣座 11的卡合部 111后, 通过联动结构拉动锁钩 26向后移动, 以使锁钩 26外端的钩状结构 261与闩销 112的圆心重合, 从而使第 一部件 1与第二部件 2的连接更加稳固, 不容易脱离。
[0065] 参见图 6, 在本实施例中, 把手 24包括中空的壳体 241、 安装在壳体 241内的离 合件 242以及和盖设在壳体 241—侧的盖板 243。 壳体 241的内端套设在固定轴 27 上, 壳体 241内壁上形成有一个沿平行于第一方向 D3的方向延伸的安装轴 244。 离合件 242包括离合齿轮 245和拨动杆 246, 离合齿轮 245通过键连接方式不可转 动地套设在固定轴 27上, 拨动杆 246的中部枢接在安装轴 244上, 拨动杆 246具有 相对的第一端 246a和第二端 (图未示) , 其第一端 246a形成有与离合齿轮 245啮 合的齿, 拨动杆 246的第二端上连接有一个按钮 247, 按钮 247伸出壳体 241外部 以用于按压, 在压下按钮 247后, 拨动杆 246的第一端 246a抬起并与离合齿轮 245 分离。 安装轴 244上套设有用于拨动杆 246复位的弹性元件 248, 弹性元件 248的 两端分别与安装轴 244和壳体 241内壁抵接, 弹性元件 248为弹簧, 在按钮 247的 下压力消除后, 弹性元件 248可使拨动杆 246复位, 其第一端 246a在弹性元件 248 的作用下再次与离合齿轮 245啮合。 这样, 当把手 24沿一方向拨动至极限位置吋 , 可按下按钮 247, 并反向拨动把手 24至极限位置, 再于松幵按钮 247后沿原方 向继续拨动把手 24。
[0066] 参见图 7, 本实施例提供的 LED拼装屏, 包括多个 LED箱体 200, 每个 LED箱体 200内分别安装有一个 LED显示屏 (图未示) , 相邻的两个 LED箱体 200之间分别 通过一个上述的锁扣组件 100连接。 上述锁扣组件 100中的第一部件 1固定安装在 其中一个 LED箱体 200上, 第二部件 2固设在另一 LED箱体 200上。 在本实施例中 , 每个 LED箱体 200的左右侧分别安装有一个第一部件 1和一个第二部件 2, 这样 , 通过该 LED箱体 200的第二部件 2与另一 LED箱体 200的第一部件接合, 以实现 相邻的两个 LED箱体 200的固定连接和接通。
[0067] 下面结合附图 1至图 7详细说明下相邻的 LED箱体 200之间的连接安装步骤: [0068] 将相邻的两个 LED箱体 200拼接后, 拨动第二部件 2上的把手 24, 把手 24的通过 固定轴 27带动驱动齿轮 251和齿条 252联动, 从而将第二连接器 22推出, 并与另 一 LED箱体 200上的第一连接器 12接合, 同吋, 锁扣座 11转动以与另一 LED箱体 2 00上的卡合部 111卡合。
[0069] 上述的 LED拼装屏, 通过把手 24的拨动, 就使得相邻的各 LED箱体 200和电源 信号连接器可以同吋锁定, 一举多得, 节约吋间和安装效率, 这样, 可快速实 现拆卸, 方便使用, 大大提高了安装及拆卸的效率。
[0070] 以上仅为本发明的较佳实施例而已, 并不用以限制本发明, 凡在本发明的精神 和原则之内所作的任何修改、 等同替换或改进等, 均应包含在本发明的保护范 围之内。
