Description
本发明涉及日常生活用品领域,尤其涉及一种平衡落地物品的自动平衡器。The invention relates to the field of daily necessities, and in particular to an automatic balancer for balancing items on the ground.
日常生活中所用的冰箱、洗衣机、落地空调等很多落地物品需要放置平稳才能正常使用,而通常地面本身的平整度达不到平稳放置的要求,需要在底部垫一些东西或是通过调整螺栓来寻找平衡,有些冰箱或洗衣机带有螺栓可调节的底脚,但是需要人工进行调节,这些产品往往都是安装在房间的边角位置,所以通过人工调节不太方便,而且这些底脚一般都是刚性的,不具备减振的功能。Many floor items such as refrigerators, washing machines, floor air conditioners, etc. used in daily life need to be placed in order to be used normally. Usually, the flatness of the ground itself does not meet the requirements of smooth placement. It is necessary to pad some things at the bottom or find them by adjusting bolts. Balanced, some refrigerators or washing machines have bolt-adjustable feet, but they need to be adjusted manually. These products are often installed in the corners of the room, so it is not convenient to adjust manually, and these feet are generally rigid. Does not have the function of damping.
有鉴于此特提出本发明。The present invention has been made in view of the above.

本发明的工作原理为:使用时,将本产品垫在冰箱或洗衣机等落地物品的底部,垫板7与地面接触,通油底板11与洗衣机、冰箱等落地物品接触,通油底板11可以通过第一安装 孔110直接与洗衣机等落地物品固定连接,由于两个油囊8是连通的,且里面有液压油,两个油囊8的受到压力相同的情况下,液面始终保持同一水平位置,当地面不平时,两个油囊受力不平衡,一个油囊8内的液压油会流入另一个油囊8,使两个油囊护套6一个伸长,另一个缩短,从而两个通油底板11的高度自动适应地面,以适应压力的变化,从而使两个通油底板11始终支撑在落地物品和地面之间,因此,使用时尽量将两个平衡底脚11安装在所受压力基本相同的两个点上。由于出油口101的直径要比油囊8的主体83的直径小,液压油流通时产生的阻力较大,可以起到缓冲减振的作用,特别适合洗衣机等有振动的物品使用。The working principle of the invention is: when using, the product is placed on the bottom of the floor item such as a refrigerator or a washing machine, the backing plate 7 is in contact with the ground, and the oil-passing bottom plate 11 is in contact with the floor-standing articles such as the washing machine and the refrigerator, and the oil-passing bottom plate 11 can pass The first mounting hole 110 is directly fixedly connected with a floor-standing article such as a washing machine. Since the two oil bladders 8 are in communication and there is hydraulic oil inside, and the two oil bladders 8 are subjected to the same pressure, the liquid surface always maintains the same horizontal position. When the local surface is not flat, the two oil bladders are unbalanced, and the hydraulic oil in one oil bladder 8 will flow into the other oil bladder 8, so that the two oil bladder sheaths 6 are elongated and the other is shortened, thereby The height of the oil-passing bottom plate 11 is automatically adapted to the ground to adapt to the change of pressure, so that the two oil-passing bottom plates 11 are always supported between the floor-standing article and the ground. Therefore, the two balance feet 11 are installed as much as possible during use. The pressure is basically the same at two points. Since the diameter of the oil outlet 101 is smaller than the diameter of the main body 83 of the oil bladder 8, the resistance generated when the hydraulic oil flows is large, and it can function as a buffer and vibration damping, and is particularly suitable for use in a vibrating article such as a washing machine.
