[0027] 图 6是本发明旋转力传递组件实施例中旋转力接收头与调整滑块配合的结构图 [0028] 以下结合附图及实施例对本发明作进一步说明。
发明实施例
本发明的实施方式
[0029] 参见图 1至图 6 , 旋转力传递组件 1包括鼓齿轮 5、 旋转力传递部件以及旋转力接 收头 2, 旋转力接收头 2用于接收来自激光打印机主机驱动轴的旋转力。 鼓齿轮 5 紧配于感光鼓的鼓筒的一个轴向端， 鼓齿轮 5的轴线与鼓筒的轴线重合， 并与鼓 筒同步绕它们共同的轴线旋转。 其中， 感光鼓可旋转地支承于处理盒的盒体两 端壁之间。
[0030] 参见图 2和图 3， 鼓齿轮 5的轴向一端具有敞口的容纳腔 54， 鼓齿轮 5的另一端开 设有与容纳腔 54连通的导向孔 52, 导向孔 52的内壁具有两个径向凸出且相对设 置的筋条 53 , 鼓齿轮 5的外圆周面上具有传动齿圈 51。 本实施例导向孔 52的横截 面形状为鼓形， 两个筋条 53分别位于鼓形导向孔 52的两个相对且互相平行的平 面上。
[0031] 参见图 1、 图 4和图 5， 旋转力传递部件包括调整滑块 3、 槽部件 4和中心轴 7， 中 心轴 7的一端与鼓齿轮 5固定连接， 中心轴 7的另一端位于容纳腔 54内。 中心轴 7 具有头部 71、 安装部 72和杆部 73， 头部 71位于杆部 73的一端， 安装部 72邻接头 部 71地位于杆部 73上， 并且头部 71和安装部 72均位于容纳腔 54内， 杆部 73的另 一端设有沿径向贯穿杆部 73的固定孔 74。 杆部 73的另一端穿过导向孔 52并与两 个筋条 53过盈配合地固定连接， 固定孔 74可插入固定插销 6 , 固定插销 6位于鼓 齿轮 5的另一端的外侧， 安装部 72抵靠在容纳腔 54的底部 55。 因此， 固定插销 6 和安装部 72限制了中心轴 7相对于鼓齿轮 5在轴向的移动， 并且杆部 73的另一端 与两个筋条 53过盈配合地限制了中心轴 7与鼓齿轮 5的相对旋转运动， 从而使中 心轴 7与鼓齿轮 5固定连接。 本实施例头部 71为呈鼓形的薄板状， 杆部 73的横截 面形状呈鼓形， 杆部 73的横截面积小于头部 71的横截面积。
[0032] 槽部件 4为开有槽的圆柱体， 其顶部具有沿径向贯通的上滑槽 41， 底部具有径 向贯通的下滑槽 42, 该上滑槽 41和下滑槽 42的横截面大致呈“凸”字形， 上滑槽 41 和下滑槽 42在空间上相互垂直， 并且上滑槽 41和下滑槽 42均位于鼓齿轮 5的容纳 腔 54内。 调整滑块 3可在上滑槽 41内相对于槽部件 4沿径向往复滑动地配合， 即 在第一方向上滑动。 中心轴 7的头部 71可在下滑槽 42内相对于槽部件 4沿径向往 复滑动地配合， 即在第二方向上滑动。 从而， 第一方向和第二方向均垂直于鼓 齿轮 5的轴线。
[0033] 旋转力接收头 2与调整滑块 3之间设有可绕旋转力接收头 2的轴线旋转的转动限 位销 8。 旋转力接收头 2大致呈一类似火炬的形状， 由自外向里（图 5当中是自上向 下）依次变细的外端部 23、 中间部 22和轴部 21构成， 轴部 21设有供转动限位销 8穿 过的销孔 25。 位于外端部 23向外伸出地设置有两个凸爪 24, 两个凸爪 24关于旋 转力接收头 2的轴线形成中心对称， 两个凸爪 24可与激光打印机主机驱动轴咬合
[0034] 参见图 5和图 6， 调整滑块 3包括大致呈鼓形的基座 32和位于基座 32上的圆柱形 凸台 31， 基座 32在上滑槽 41内相对于槽部件 4沿径向往复滑动地配合， 即在第一 方向上滑动。 在基座 32的底面上具有容纳转动限位销 8的凹槽 34， 凹槽 34内具有 相对设置的第一限位挡块 35和第二限位挡块 36。 凸台 31开设有在轴向与凹槽 34 贯通的通孔 33 , 该通孔 33的直径大于旋转力接收头 2的轴部 21的直径， 且小于旋 转力接收头 2的中间部 22的直径， 因此仅可供轴部 21穿过。 其中， 旋转力接收头 2的中间部 22抵靠在凸台 31上。 凹槽 34内设有两个相对设置的第一限位挡块 35和 第二限位挡块 36 , 使得转动限位销 8能够且仅能够在一定角度范围内绕旋转力接 收头 2的轴线旋转。
[0035] 当具有上述旋转力传递组件 1的处理盒放置至激光打印机内部时， 利用旋转力 传递组件 1的调整滑块 3在上滑槽 41内沿第一方向滑动，同时中心轴 7也在下滑槽 42 内沿第二方向滑动， 从而使旋转力传递组件 1的旋转力接收头 2的凸爪 24朝一固 定方向放置， 这时旋转力接收头 2可以实现与激光打印机主机驱动轴的转动配合 。 如果旋转力接收头 2的凸爪 24与激光打印机主机驱动轴存在干涉时， 旋转力接 收头 2可自行绕其轴线转动一定角度， 从而自动调整凸爪 24的位置避免与激光打 印机主机驱动轴干涉。 激光打印机开始工作， 两个凸爪 24与激光打印机主机驱 动轴稳定配合从而驱动感光鼓稳定旋转。 因此， 处理盒在落机过程中不会受到 某些零部件的阻碍和干扰而产生卡死的现象， 与激光打印机主机驱动轴的配合 更为顺畅。
[0036] 当需要从激光打印机中取出处理盒时， 手动拿住处理盒手柄， 向激光打印机的 外侧拉动处理盒， 使处理盒向外侧移动一定距离， 这时旋转力传递组件 1的调整 滑块 3在上滑槽 41内沿第一方向滑动，同时中心轴 7也在下滑槽 42内沿第二方向滑 动， 从而使旋转力接收头 2在垂直于激光打印机主机驱动轴的轴线方向平移， 使 旋转力接收头 2与激光打印机主机驱动轴相互错位， 实现脱离接触， 此时可以顺 畅地取出处理盒。
[0037] 具有上述旋转力传递组件 1的处理盒落机更平稳， 打印更稳定， 激光打印机主 机驱动轴与处理盒的旋转力接收头可正确且充分地咬合， 提高了处理盒的兼容 性， 性价比更高。
工业实用性
[0038] 本发明旋转力传递组件的中心轴一端与鼓齿轮固定连接， 中心轴的另一端位于 容纳腔内， 槽部件具有在空间上相互垂直的上滑槽和下滑槽， 上滑槽和下滑槽 均位于容纳腔内， 调整滑块在第一方向上与上滑槽形成相对滑动地配合， 旋转 力接收头可绕其轴线旋转地与调整滑块连接， 中心轴的另一端在第二方向上与 下滑槽形成相对滑动地配合， 具有该旋转力传递组件的处理盒在落机过程中不 会受到某些零部件的阻碍和干扰而产生卡死的现象， 与激光打印机主机驱动轴 的配合更为顺畅， 处理盒落机更平稳， 打印更稳定。 同时， 激光打印机主机驱 动轴与处理盒的旋转力接收头可正确且充分地咬合， 提高了处理盒的兼容性， 性价比更高。
[0039] 以上实施例， 只是本发明的较佳实例， 并非来限制本发明实施范围， 故凡依本 发明申请专利范围的构造、 特征及原理所做的等效变化或修饰， 均应包括于本 发明专利申请范围内。
