Description

Vibration damper for washing machine Technical Field The utility model relates to the technical field of washing machines, in particular to a vibration damper of a washing machine. Background In the running process of the washing machine, the washing machine can vibrate due to the unbalanced load of washing articles and the action of centrifugal force, in order to ensure stable operation of the washing machine, the existing washing machine is provided with a vibration damping device, the existing vibration damping device is suspended between the outer box body of the washing machine and the inner barrel of the washing machine, when the washing machine vibrates, the vibration damping spring and the friction element buffer the force generated by vibration at the same time, the friction element can participate in the vibration damping process from the beginning, so that the abrasion speed of the friction element is high, the friction element is easy to fail, and the friction element needs to be replaced frequently. Accordingly, there is a need for a vibration damping device for a washing machine that solves the above-mentioned problems. Disclosure of utility model The utility model provides a vibration damper for a washing machine, which is characterized in that a friction sleeve and a spring upper support are arranged in a split mode, so that the friction sleeve and the spring upper support can slide independently, and the vibration damping effect is realized. The technical scheme of the utility model is realized as follows: The damping device for the washing machine comprises a hanging rod, wherein a hanging rod seat is arranged at the upper end of the hanging rod, a spring lower support is arranged at the lower end of the hanging rod, a supporting seat and a spring upper support are slidably arranged on the hanging rod, the supporting seat and the spring upper support are arranged together, a damping spring is arranged between the spring upper support and the spring lower support, the damping spring is sleeved on the hanging rod, a friction sleeve is sleeved in the spring upper support or in the supporting seat or between the supporting seat and the spring upper support, and a friction element is arranged in the friction sleeve and is in close contact with the hanging rod. As a preferable technical scheme, a buffer gap is arranged in the spring upper support or in the supporting seat or between the supporting seat and the spring upper support. As an optimized technical scheme, the friction sleeve is sleeved in the spring upper support, the buffer gap is arranged in the spring upper support, and the buffer gap is arranged below the supporting seat. As an optimized technical scheme, the spring upper support is provided with an oil storage cavity, and the oil storage cavity is communicated with the friction sleeve. As a preferable technical scheme, the oil storage cavity is annular, and a plurality of through grooves used for communicating the oil storage cavity and the friction sleeve are formed in the inner wall of the oil storage cavity. As a preferable technical scheme, a plurality of vertically arranged partition plates are uniformly distributed in the oil storage cavity along the circumference. As a preferable technical scheme, the upper end and the lower end of the inner peripheral surface of the friction sleeve are respectively provided with a plurality of limiting blocks for limiting the friction element. As a preferable technical scheme, the supporting seat is arranged above the spring upper support, and the supporting seat and the spring upper support are clamped or inserted together. As a preferred technical solution, a compression spring is disposed in the buffer gap. As a preferable technical scheme, the upper end of the compression spring is abutted against the supporting seat, and the lower end of the compression spring is abutted against the friction sleeve.
