参见图1,本实用新型提供一种清洁用具,其特征在于,清洁用具包括支撑杆、主调杆4、微调杆9、刮板8和清洁盘7,主调杆4的中部铰接于支撑杆的顶部且通过第一固定件固定,清洁盘7设置于主调杆4的一端,刮板8通过微调杆9与主调杆4的另一端相连接;其中,微调杆9的长度方向与刮板8的长度方向相垂直。Referring to Fig. 1 , the utility model provides a cleaning tool, which is characterized in that the cleaning tool includes a support rod, a main adjustment rod 4, a fine adjustment rod 9, a scraper 8 and a cleaning disc 7, and the middle part of the main adjustment rod 4 is hinged to the support rod and fixed by the first fixture, the cleaning plate 7 is arranged on one end of the main adjustment rod 4, and the scraper 8 is connected with the other end of the main adjustment rod 4 through the fine adjustment rod 9; The length directions of the plates 8 are perpendicular.

通过上述技术方案,将主调杆4的中部铰接在支撑杆的顶部且使用第一固定件将二者固定,再将清洁盘7设置在主调杆4的一端,将刮板8通过微调杆9与主调杆4的另一端相连接;这样松开第一固定件来调节主调杆4与支撑杆之间的角度以改变清洁盘7和刮板8与窗户玻璃接触后的角度以便于摩擦清洁,当位置和角度调节好后再紧固第一固定件和微调杆9就可以进行清洁操作了。Through the above technical scheme, the middle part of the main adjustment rod 4 is hinged on the top of the support rod and the first fixing piece is used to fix the two, and then the cleaning disc 7 is arranged on one end of the main adjustment rod 4, and the scraper 8 is passed through the fine adjustment rod 9 is connected with the other end of main adjusting rod 4; Unclamp the first fixture like this and adjust the angle between main adjusting rod 4 and support bar to change the angle after cleaning disc 7 and scraper 8 contact with window glass so that Friction cleaning, when the position and angle are adjusted, the first fixing member and the fine-tuning rod 9 can be tightened and the cleaning operation can be carried out.

在上述调节过程中,为了便于调节刮板8与窗户玻璃之间的角度,以使得刮板8紧贴在玻璃上,更有效地将玻璃上的水迹刮擦干净,优选地,微调杆9与主调杆4之间通过铰链件相连接且通过第二固定件固定微调杆9和主调杆4的相对位置。In the above-mentioned adjustment process, in order to facilitate the adjustment of the angle between the scraper 8 and the window glass, so that the scraper 8 is closely attached to the glass, and the water stains on the glass are more effectively wiped clean, preferably, the fine-tuning lever 9 It is connected with the main adjustment rod 4 through a hinge and the relative position of the fine adjustment rod 9 and the main adjustment rod 4 is fixed by a second fixing member.

本实施方式中,为了方便伸长支撑杆来擦洗较高处的玻璃以及缩短支撑杆来清洁较低处的玻璃,避免由于长时间踮脚或弯腰导致体力消耗过快,造成清洁人员劳累过度,优选支撑杆为伸缩杆。这样,通过伸缩杆方便快捷地伸长和缩短就能够清洁高低不同的玻璃,优化清洁效果。In this embodiment, in order to facilitate the extension of the support rod to scrub the glass at a higher place and shorten the support rod to clean the glass at a lower place, to avoid excessive physical exertion due to prolonged standing on tiptoe or bending over, resulting in overwork of the cleaning personnel, Preferably the support rod is a telescopic rod. In this way, glass with different heights can be cleaned by conveniently and quickly extending and shortening the telescopic rod, and the cleaning effect is optimized.

在上述伸缩杆的调节过程中,为了简化伸缩杆的结构,方便清洁人员快速的组装、调节以及拆卸,节省清洁时间,减少体力消耗,优选地,伸缩杆包括第一支管1和第二支管2,第二支管2套设于第一支管1的外周壁上且第二支管2的顶部设有紧固件以固定第一支管1和第二支管2的相对位置;主调杆4的中部铰接于第一支管1的顶部。In the adjustment process of the above-mentioned telescopic rod, in order to simplify the structure of the telescopic rod, facilitate the quick assembly, adjustment and disassembly of the cleaning staff, save cleaning time and reduce physical exertion, preferably, the telescopic rod includes a first branch pipe 1 and a second branch pipe 2 , the second branch pipe 2 is sleeved on the outer peripheral wall of the first branch pipe 1 and the top of the second branch pipe 2 is provided with a fastener to fix the relative position of the first branch pipe 1 and the second branch pipe 2; the middle part of the main adjusting rod 4 is hinged At the top of the first branch pipe 1.

此外,紧固件的结构形式可以是本领域中常见的任何一种能够起到固定和放松功能的实施方式,但从方便更换和节约成本的角度考虑,优选在第二支管2的外周壁的顶部设有外螺纹且紧固件为紧固螺帽。In addition, the structural form of the fastener can be any common implementation in the field that can perform the functions of fixing and loosening. The top is provided with an external thread and the fastener is a fastening nut.

本实施方式中,为了方便高层住户即使处于室内也能够很方便地将支撑杆伸出室外对外侧玻璃进行清洁,优选在支撑杆的底部设有手柄。进一步地,为了方便调节手柄与支撑杆之间的角度,使得支撑杆能够更有力地将清洁盘7或刮板8抵靠在玻璃表面,优选地,手柄包括第一支杆5和第二支杆6,第一支杆5的一端与支撑杆的底部相连接,另一端与第二支杆6相铰接并通过第三固定件以固定第一支杆5和第二支杆6的相对位置。这样,通过转动第一支杆5和第二支杆6来调节好两者之间的角度,使得第一支杆5带动支撑杆朝向外侧玻璃转动以使得清洁盘7或刮板8紧紧抵靠在玻璃表面,再通过紧固第三固定件将第一支杆5和第二支杆6的铰接处固定,此时,即使清洁者使用较大的力也不会轻易改变第一支杆5和第二支杆6之间的角度,使清洁盘7或刮板8始终贴合在玻璃表面进行反复摩擦清洁。In this embodiment, in order to facilitate high-rise residents to extend the support rod outside to clean the outer glass even if they are indoors, a handle is preferably provided at the bottom of the support rod. Further, in order to facilitate the adjustment of the angle between the handle and the support rod, so that the support rod can more forcefully press the cleaning disc 7 or scraper 8 against the glass surface, preferably, the handle includes a first support rod 5 and a second support rod Rod 6, one end of the first pole 5 is connected to the bottom of the support pole, the other end is hinged with the second pole 6 and the relative position of the first pole 5 and the second pole 6 is fixed by a third fixing member . Like this, adjust the angle between the two by rotating the first pole 5 and the second pole 6, so that the first pole 5 drives the support pole to rotate towards the outside glass so that the cleaning disc 7 or the scraper 8 are tightly pressed against Lean against the glass surface, and fix the hinge of the first pole 5 and the second pole 6 by fastening the third fixing piece. At this time, even if the cleaner uses a large force, the first pole 5 will not be easily changed. The angle between the second pole 6 and the cleaning disc 7 or the scraper 8 is always attached to the glass surface for repeated friction cleaning.

由于整个清洁过程中使用水或清洁剂,一旦水或清洁剂沾湿手柄,清洁人员手持手柄进行调节或者擦拭清洁时容易手部打滑,将整个清洁用具摔坏,甚至从高层窗口落下砸中楼下的人或物,造成十分严重的后果,为了避免手持清洁用具时发生打滑的现象,优选地,第二支杆6的端部设有防滑套10。Since water or detergent is used throughout the cleaning process, once the handle is wetted by water or detergent, the cleaning staff will easily slip when adjusting or wiping the handle with the handle, breaking the entire cleaning tool, or even falling from the high-rise window and hitting the middle building People or things under it will cause very serious consequences. In order to avoid slipping when holding the cleaning tool, preferably, the end of the second pole 6 is provided with an anti-slip sleeve 10 .
