Description

自动平衡器Automatic balancer 技术领域Technical field
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.
背景技术Background technique
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.
发明内容Summary of the invention
本发明提供一种可以自动调节平衡并且具有减振功能的自动平衡器。The present invention provides an automatic balancer that can automatically adjust balance and has a vibration damping function.
为解决上述技术问题，本发明的技术方案是：一种自动平衡器，包括两个平衡底脚，两个所述平衡底脚通过连接板固定连接，每个所述平衡底脚均包括通油底板、油囊、导向套、油囊护套、油囊压板和垫板，所述通油底板内设有至少一条油道，所述油道的一端设有出油口，另一端与所述油囊连通，两个所述平衡底脚的出油口通过管连接，连接板可以使两个平衡底脚的位置相对固定，并且可以保护管；In order to solve the above technical problem, the technical solution of the present invention is: an automatic balancer comprising two balance feet, two of which are fixedly connected by a connecting plate, each of which includes an oil passage a bottom plate, an oil bladder, a guide sleeve, an oil bladder jacket, an oil bladder pressure plate and a backing plate, wherein the oil passage bottom plate is provided with at least one oil passage, one end of the oil passage is provided with an oil outlet, and the other end is The oil bladder is connected, and the oil outlets of the two balance legs are connected by a pipe, and the connecting plate can fix the positions of the two balance feet relatively, and can protect the pipe;
所述油囊位于所述通油底板的下方，所述油囊内装有液压油，液压油受力可以通过油管在两个平衡底脚之间流动互补，所述油囊包括主体和囊口，所述主体的直径大于所述囊口的直径，所述囊口与所述通油底板的下端面密封连接，所述主***于所述油囊护套内，所述主体夹在所述油囊压板和油囊护套的底面之间，所述出油口的直径小于所述囊口的直径；The oil bladder is located below the oil-passing bottom plate, and the oil bladder is filled with hydraulic oil, and the hydraulic oil can be forced to flow through the oil pipe between the two balance legs, the oil bladder includes a main body and a capsule mouth. The diameter of the main body is larger than the diameter of the capsule mouth, the capsule mouth is sealingly connected with the lower end surface of the oil passage bottom plate, the main body is located in the oil bladder sheath, and the main body is clamped in the oil bladder Between the pressure plate and the bottom surface of the oil bladder sheath, the diameter of the oil outlet is smaller than the diameter of the capsule;
所述油囊护套沿上下方向滑动安装于所述导向套内，所述油囊护套的底端伸出所述导向套的底端，所述导向套位于所述通油底板的下方，且与所述通油底板通过紧固件固定连接；The oil bladder sheath is slidably mounted in the guiding sleeve in an up-and-down direction, a bottom end of the oil bladder sheath protrudes from a bottom end of the guiding sleeve, and the guiding sleeve is located below the oil-passing bottom plate, And being fixedly connected to the oil passage bottom plate by a fastener;
所述油囊压板通过紧固件固定安装于所述通油底板的下方，所述油囊压板为环形且套在所述油囊的囊口外周，所述油囊压板与所述导向套相匹配，当两个平衡底脚的其中一个油囊压板向下滑动时，油囊压板和导向套就挤压油囊，使油囊的空间变小，液压油就会经过通油板和油管流向另外一只平衡底脚，从而增加另外一只平衡底脚的高度；The oil bladder pressure plate is fixedly mounted under the oil-passing bottom plate by a fastener, the oil bladder pressure plate is annular and sleeved around the outer periphery of the oil capsule, and the oil bladder pressure plate is opposite to the guide sleeve Matching, when one of the two balance feet slides down, the oil bladder pressure plate and the guide sleeve squeeze the oil bladder, so that the space of the oil bladder becomes smaller, and the hydraulic oil flows through the oil passage and the oil pipe. The other balances the foot to increase the height of the other balance foot;
所述垫板固定安装于所述油囊护套的下方。The backing plate is fixedly mounted below the oil bladder jacket.
由于采用了上述技术方案，本产品在使用时，垫在冰箱或洗衣机等落地物品的底部，垫板位于地面上，通油底板承托在落地物品上，就可以自动的调节平衡，其工作原理为，由于两个油囊是连通的，且里面有液压油，两个油囊受到的压力相同的情况下，他们的液面始终是要保持同一水平位置的，当受到的压力不平衡时，一个油囊内的液压油会流入另一个油囊，使两个平衡底脚的高度发生改变，始终支撑在落地物品和地面之间，保证落地物品的平稳放置，不使落地物品的一端悬空。而且，由于出油口的直径要比油囊主体的直径小，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。Due to the above technical solution, when the product is used, it is placed at the bottom of the floor object such as a refrigerator or a washing machine, the pad is located on the ground, and the oil-passing floor is supported on the floor item, and the balance can be automatically adjusted. Therefore, since the two oil bladders are connected and there is hydraulic oil inside, and the two oil bladders are subjected to the same pressure, their liquid levels are always maintained at the same horizontal position. When the pressure is unbalanced, The hydraulic oil in one oil sac will flow into the other oil sac, so that the height of the two balance feet changes, and is always supported between the ground objects and the ground to ensure the smooth placement of the ground objects, and does not make one end of the ground objects hang. Moreover, since the diameter of the oil outlet is smaller than the diameter of the main body of the oil bladder, the resistance generated by the flow of the hydraulic oil is large, and the vibration damping effect can be achieved, and it is particularly suitable for use in vibration-containing articles such as washing machines.

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.
