Description

一种拖把杆的旋转驱动机构 技术领域
本发明涉及一种拖把的部件， 尤其涉及一种能带动拖把杆进行旋转的驱动机构。
背景技术
目前市场上有一种拖把头可以旋转的拖把，它是通过往复下压拖把杆使拖把头产生高速 旋转， 利用离心力将拖把头中的水份甩干。 这种拖把的拖把杆由上管和下管两部分组成， 上 管与下管在轴向可以产生互相移动。上管的下端罩套在下管的上端， 驱动机构设于上管和下 管的内部， 上管和下管通过驱动机构活动连接在一起。 只要下压上管， 使上管和下管之间在 轴向产生相对移动， 其内部驱动机构就驱动下管旋转， 连接在下管下端的拖把头同时也跟着 旋转脱水。因为这种拖把的拖把头不需要使用者用手去清浇和挤水，所以深受广大用户欢迎。 但是， 这种拖把在拖地时， 拖把头会产生旋转现象， 所以拖地前， 首先要操作锁定机构将下 管与上管锁定在一起， 不让下管与上管在轴向产生相互位移， 然后再进行拖地。 在拖把头需 要清洗时， 要首先打开上管与下管的锁定机构， 才能对拖把头进行清洗和甩干脱水。 由此可 见， 这种旋转拖把杆机构较多， 生产成本较高， 而且使用起来操作也较麻烦。
发明内容
本发明主要目的是解决现有技术所存在的不足，从而提出一种在拖地时无需操作锁定机 构， 拖把头也不会旋转， 拖地省力的拖把杆旋转驱动机构。
本发明的上述技术问题主要是通过下述技术方案得以解决的： 一种拖把杆的旋转驱动 机构， 其特征在于： 具有拖把杆和设置于拖把杆上的驱动机构； 所述驱动机构包括：
一传动轴， 所述传动轴固定连接在拖把杆上， 其上设有传动轴环形齿面；
一传动套， 所述传动套套在传动轴外面， 并可沿着传动轴上下滑动， 其侧面设有两个以 上等分导头， 下端面设有与传动轴环形齿面形成上下啮合关系的传动套环形齿面；
一接头， 所述接头位于传动套上面；
一连接轴， 所述连接轴位于传动轴、 传动套和接头的中心， 通过销接， 将三者连接为一 体；
一驱动套， 所述驱动套罩套在接头、 传劫轴、 传动套和拖把杆的外面， 内壁设有两条以 上等分螺旋导槽， 并与接头、 传劫轴、 传动套和拖把杆形成相对运动关系；
所述拖把杆上设有把手， 所述把手与拖把杆固定连接。
本发明的技术方案还可以进一步完善：
作为优选， 所述传动轴上半部直径小于下半部直径， 大小直径之间连接处形成的台阶为 传动轴环形齿面， 传动轴中心设有轴向沉孔， 所述沉孔直径与连接轴外径配合；
所述传动套的导头设在侧面， 所述导头的数量与驱动套内壁的导槽条数相配合， 所述传 动套下端面为传动套环形齿面， 所述传动套环形齿面与传动轴环形齿面相啮合， 所述传动套 轴向设有通孔， 所述通孔内径与传动轴上半部 （外） 直径滑动配合；
所述传动轴上半部长度长于传动套高度。
本发明的有益效果是：
由于采用了上述技术方案， 拖地时， 手握在把手上， 不需要操作锁定机构， 也不会下压 或上提驱动套， 因而不会通过驱动机构带动拖把杆和拖把头旋转， 其结构简单， 拖地操作也 比较省力。

具体实施方式
下面通过实施例并结合附图， 对本发明的技术方案作进一步具体说明。
实施例 1 :
如图 1至 15所示的一种拖把杆旋转驱动机构， 包括拖把杆和驱动机构。 所述驱动机构 设置于所述拖把杆 6的上端， 包含有一传动轴 4， 一传动套 3， 一接头 2， 一连接轴 5， 一驱 动套 1。 所述传动轴上半部 42直径小于下半部 41直径， 所述传动轴 4大直径端与拖把杆 6 上端固定连接， 所述传动轴 4大小直径之间连接处形成的台阶为传动轴环形齿面 11， 传动 轴 4中心设有轴向沉孔， 所述沉孔直径与连接轴 5外径配合（如图 14、 15所示）； 所述传动 套 3套在传动轴 4上半部 42小直径外面， 并可沿着小直径上下滑动， 所述传动套 3两侧设 有二个导头 12， 下端设有与传动轴环形齿面 11形成上下啮合关系的传动套环形齿面 9 (如 图 11、 12、 13所示）； 所述接头 2位于传动套 3上面， 当上、 下齿面啮合时， 所述接头 2与 传动套有一定距离 （传动轴上半部长度长于传动套高度）； 所述连接轴 5穿过传动轴 4、 传 动套 3和接头 2的中心， 通过销接（与传动轴和接头）将三者连接为一体； 所述驱动套 1罩 套在接头 2、 传劫轴 4、 传动套 3和拖把杆 6的外面， 所述驱动套 1 内壁设有两条螺旋导槽 (如图 10所示）， 所述传动套 3上的导头 12置于所述驱动套 1的螺旋导槽 10内. 驱动套 1 下端口设有套盖 7， 所述套盖 7以螺纹连接的方式固定连接在所述驱动套 1的下端。
在驱动套 1下面的拖把杆 6上采用销接固定连接有把手 8。
采用上述技术结构的拖把杆， 当连接在拖把杆 6下端的拖把头需要甩干脱水时， 上提驱 动套 1 (如图 3、 4、 5所示）， 其内壁的螺旋导槽 10下侧面 13向左上方推压传动套 3上的 导头 12， 使传动套环形齿面 9与传动轴环形齿面 11分离， 同时使传动套 3开始按逆时计方 向旋转。 驱动套 1上提到最高点后， 下压驱动套 1 (如图 6、 7、 8所示）， 螺旋导槽 10的上 侧面 14向右下方推压传动套 3的导头 12， 使传动套 3的环形齿面 9向传动轴 4的环形齿面 11靠拢， 并使传动套 3开始按顺时针方向旋转。 继续下压驱动套 1 (如图 9所示）， 传动套 环形齿面 9与传动轴环形齿面 11齿合， 并带动传动轴 4和拖把杆部分一起按顺时针方向旋 转。 驱动套 1下压到最低点后， 再上提驱动套 1至最高点， 再下压。 如此往复， 拖把杆转速 越来越快， 拖把头中的水份就被充分甩干。
拖地时， 只要手握驱动套 1和把手 8， 拖把头不会产生旋转。
实施例 2:
如图 16、 17所示为旋转驱动机构设置在拖把杆中部的实例。 此时， 拖把杆分割成上拖 把杆 61和下拖把杆 62， 上拖把杆 61的下端与接头 2的上端固定连接， 下拖把杆 62的上端 与传动轴 4的下端固定连接， 也就是说通过传动机构把上、 下拖把杆固定连接在一起， 把手 8安装在上拖把杆 61的端部。 其余与实施例 1相同。
拖地时， 手握把手 8和驱动套 1， 拖把头也不会产生旋转。
