Description

Technical Field

[0001] This utility model belongs to the field of balance block technology, specifically a balance block for increasing the lifespan of a washing machine. Background Technology

[0002] The main function of a balance weight is to increase the stability of a washing machine and prevent vibration and displacement during operation. When the washing machine is spinning or rotating at high speed, if the clothes are unevenly distributed, the balance weight can help the washing machine maintain a good balance through its weight and position. By maintaining balance, the balance weight can reduce the wear and tear on internal parts of the washing machine (such as bearings and motors), thereby extending the overall service life of the washing machine. The balance weight ensures that the washing machine rotates more smoothly, which helps to improve the washing effect and make clothes cleaner. However, existing washing machine balance weights cannot adjust their weight according to the needs of different washing machine models, resulting in the balance weight not meeting the requirements, which increases wear and tear when the washing machine vibrates and reduces its service life. Utility Model Content

[0003] In view of the above situation and to overcome the defects of the prior art, this utility model provides a balance block that increases the life of a washing machine, effectively solving the problem that the existing washing machine balance block cannot adjust its own weight according to the needs of different washing machine models.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a balance block for increasing the lifespan of a washing machine, comprising a balance block body, support blocks fixedly installed at the four bottom corners of the balance block body, a support plate fixedly installed between the bottoms of the four support blocks, a protective shell fixedly installed on the surface of the balance block body, a pressing plate provided in the upper part of the interior of the balance block body, several counterweights provided in the lower part of the interior of the balance block body, a handwheel provided in the lower part of one side of the protective shell, a transmission assembly provided in one side of the handwheel, the transmission assembly being connected to the pressing plate in a transmission manner, and when the handwheel rotates, power is output to the pressing plate through the transmission assembly, causing the pressing plate to move down and press the several counterweights for positioning.

[0005] Preferably, the transmission assembly includes a shaft, which is fixedly installed on one side of the handwheel. The surface of the shaft is rotatably connected to the lower part of one side of the protective shell through a bushing. One end of the shaft extends into the interior of the protective shell and is fixedly installed with a worm gear. One end of the worm gear is rotatably installed with a bearing seat, and one end of the bearing seat is fixedly connected to the inner wall of one side of the protective shell.

[0006] Preferably, a worm wheel is meshed with the upper part of the worm gear surface, a rotating rod is fixedly installed in the middle of the worm wheel, four rotating sleeves are rotatably installed on the surface of the rotating rod, the lower parts of the four rotating sleeves are fixedly connected to the inner bottom of the protective shell through a fixed rod, a driving bevel gear is fixedly installed at both ends of the rotating rod, a driven bevel gear is meshed with the lower part of the surface of the two driving bevel gears, the lower parts of the two driven bevel gears are rotatably connected to the inner bottom of the protective shell, and a threaded rod is fixedly installed on the top of the two driven bevel gears through a rotating shaft, the top of the two threaded rods are rotatably connected to the inner top of the protective shell.

[0007] Preferably, the surfaces of the rotating shafts are rotatably mounted with bearings, the surfaces of the two bearings are fixedly connected to the interior of the protective shell through two fixed heads, the surfaces of the two threaded rods are threadedly connected with threaded sleeves, the sides of the two threaded sleeves that are far apart from each other are fixedly mounted with sliders, the inner walls of both sides of the protective shell are provided with grooves, the two sliders are slidably mounted inside the two grooves, and the sides of the two threaded sleeves that are close to each other are fixedly connected to the sides of the pressure plate through support arms.

[0008] Compared with the prior art, the beneficial effects of this utility model are as follows: In use, the operator stacks the required number of counterweights inside the main body of the balance block, and then the operator drives the shaft to rotate inside the bushing through the handwheel. When the shaft rotates, it drives the worm to rotate along the shaft seat. When the worm rotates, it drives the rotating rod to rotate inside the four rotating sleeves through the worm wheel. When the rotating rod rotates, it drives the two driven bevel gears to rotate through the two driving bevel gears. When the two driven bevel gears rotate, they both drive the rotating shaft to rotate inside the bearing.

[0009] When the two shafts rotate, they drive the two threaded sleeves to move downwards via the threaded rods. As the threaded sleeves move, they cause the slider to slide inside the groove, increasing the stability of the two threaded sleeves during movement. When the two threaded sleeves move downwards, they drive the pressure plate to move downwards via the support arm, pressing several counterweights for positioning. This allows the balance block of this washing machine to adjust its weight according to the needs of different washing machine models, thereby reducing wear during washing machine vibration and improving its service life.
