可变速手压旋转拖把杆 Variable speed hand pressure rotary mop lever
技术领域 Technical field
本实用新型涉及一种日常生活用品， 特别是一种可变速手压旋转拖把杆。 背景技术 The utility model relates to a daily life article, in particular to a variable speed hand pressing rotary mop bar. Background technique
为了简便拖把清洗和甩干的方法， 市场上出现了旋转拖把， 并且从双桶发展到单桶。 但 不管双桶还是单桶都遇到清洗费力的问题， 清洗过程中， 因为有水的阻力， 所以造成旋转拖 把在清洗时要比甩干费力很多。 所以大家在拖把桶或者拖把头上面增加齿轮减速机构， 来减 轻清洗时的力气。但是这种方法结构复杂， 成本很高， 因为齿轮与齿轮配合对精度要求很高， 而且齿轮之间容易被赃物附着而造成机构失效。 实用新型内容 In order to facilitate the cleaning and drying of the mop, rotary mops have appeared on the market and have evolved from double barrels to single barrels. However, no matter whether it is double-barrel or single-barrel, it is difficult to clean. During the cleaning process, because of the resistance of water, it is much more difficult to rotate the mop than to dry it. So everyone adds a gear reduction mechanism to the mop bucket or mop head to reduce the effort during cleaning. However, this method is complicated in structure and high in cost, because the gear and the gear are required to have high precision, and the gears are easily attached by the dirt to cause the mechanism to fail.
