DETAILED DESCRIPTION

[0020] The following is a further detailed description of the implementation of the present invention in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but cannot be used to limit the scope of the present invention.

[0021] like Figures 1 to 3 As shown, a washing machine drum balance ring comprises a lower balance ring 1 and an upper balance ring 7, a positioning assembly 6 is installed inside the lower balance ring 1, and the positioning assembly 6 comprises an electric push rod 601, a moving seat 602, a scissor arm 1 603, a scissor arm 2 604, a lower arm 605, a fixed seat 1 606, an upper arm 607, a fixed seat 2 608, a pressing plate 609 and a sliding rod 610, the output end of the electric push rod 601 is connected to the moving seat 602, and the surface of the moving seat 602 is connected to the scissor arm 1 603 through a rotating shaft, the middle part of the scissor arm 1 603 is connected to the scissor arm 2 604 through a rotating shaft, and the ends of the scissor arm 1 603 and the scissor arm 2 604 are connected to the lower arm 605 through a rotating shaft, the other end of the lower arm 605 is connected to the fixed seat 1 606 through a rotating shaft, and the ends of the scissor arm 1 603 and the scissor arm 2 604 away from the lower arm 605 are connected to the upper arm 607 through a rotating shaft. , the other end of the upper arm 607 is connected to the fixed seat 2 608 through a rotating shaft, and a pressing plate 609 is arranged on the top of the fixed seat 2 608, and sliding rods 610 are installed on both ends of the bottom of the pressing plate 609, the upper balance ring 7 is arranged at the front end of the lower balance ring 1, and a fixing groove 8 is opened on the front end surface of the upper balance ring 7, and a through hole 9 is opened on the rear end surface of the upper balance ring 7, the moving seat 602, the fixed seat 1 606 and the fixed seat 2 608 are parallel to each other, the sliding rod 610 penetrates the sliding groove on the surface of the moving seat 602, the fixed seat 1 606 is arranged on the outside of the electric push rod 601, the scissor arm 1 603 and the scissor arm 2 604 are distributed in a cross shape, the outer diameter of the pressing plate 609 is consistent with the inner diameter of the fixing groove 8, and the outer diameter of the pressing plate 609 is larger than the inner diameter of the through hole 9, the pressing plate 609, the fixing groove 8 and the through hole 9 are coaxially arranged, and the positioning assembly 6 is provided with four groups.

[0022] The specific operation is as follows: the electric push rod 601 extends to drive the movable seat 602 to rise, and by changing the angle between the scissor arm 1 603 and the scissor arm 2 604, the distance between the movable seat 602 and the fixed seat 2 608 is increased, so that the pressing plate 609 withdraws and moves away from the fixed groove 8, and the upper balance ring 7 and the lower balance ring 1 meet the separation conditions, which is convenient for maintenance and adding balance liquid to the lower balance ring 1.

[0023] like Figure 1 As shown, a retaining rib 2 is fixed inside the lower balance ring 1, and a liquid hole 3 is opened on the surface of the retaining rib 2. Balls 4 and isolation balls 5 are respectively arranged outside the retaining rib 2, and the number of balls 4 and isolation balls 5 is the same.

[0024] The specific operation is as follows: the interior of the lower balance ring 1 is divided into two cavities by the retaining rib 2, and the two cavities are connected through the liquid hole 3 to meet the condition of free flow of the balancing liquid in the cavity. When the drum rotates, the balancing liquid and the ball 4 cooperate with each other to compensate for the imbalance, thereby reducing the vibration of the washing machine barrel as much as possible and ensuring the normal operation of the washing machine.

[0025] In summary, when the washing machine drum balance ring is used, when the liquid adding operation is needed, the electric push rod 601 is controlled to extend to drive the moving seat 602 to rise, and the angle between the scissor arm 1 603 and the scissor arm 2 604 is changed, so that the fixed seat 2 608 is supported by the lower arm 605 and the upper arm 607 and moves in the through hole 9 in the direction away from the moving seat 602, that is, the pressing plate 609 is withdrawn from the fixed groove 8;

[0026] At this time, the upper balance ring 7 is removed, and the balance liquid can be added to the lower balance ring 1. When the addition is completed, the upper balance ring 7 and the lower balance ring 1 are covered, and the positioning assembly 6, the fixing groove 8, and the through hole 9 are adjusted to be coaxial, and then the electric push rod 601 is controlled to retract and drive the moving seat 602 to descend. By changing the angle between the scissor arm 1 603 and the scissor arm 2 604, the distance between the moving seat 602 and the fixing seat 2 608 is reduced, that is, the pressing plate 609 is located in the fixing groove 8, which can achieve the effect of fixing the upper balance ring 7 and the lower balance ring 1;

[0027] During the use of the balancing ring, the balancing liquid will flow in the two cavities under the influence of the rotation of the drum. At the same time, the balls 4 that move independently separated by the isolation balls 5 can further play a balancing role, reduce the vibration of the washing machine drum, and ensure the normal operation of the washing machine.
