Description

Technical Field

[0001] This utility model relates to the field of hinge technology, specifically a washing machine door hinge assembly. Background Technology

[0002] The washing machine door hinge is an important component of the washing machine. A washing machine door hinge typically consists of a hinge, a hinge bracket, and a hinge pin. The hinge and the hinge bracket are connected by the hinge pin, and the hinge bracket is riveted to the casing. The hinge is used to secure the front door of the washing machine.

[0003] Chinese patent discloses a washing machine door hinge (authorization announcement number CN220376954U). This patented technology uses a limiting protrusion, a fan-shaped protrusion, a second spring, and a third spring. When the limiting protrusion passes the fan-shaped protrusion, the second and third springs compress, causing the limiting protrusion to retract into a second sliding groove, thus passing through the fan-shaped protrusion. Then, the second and third springs reset, causing the limiting protrusion to slide out of the second sliding groove and engage with the fan-shaped protrusion. This creates a damping effect and limits the angle of the lid during opening and closing, preventing damage to the washing machine body due to excessive force when closing the door. However, this washing machine door hinge cannot be adjusted after fixing, requires high installation precision, and is prone to problems such as the door not being tightly fitted to the washing machine body after installation, hindering installation convenience. The door may also sag or tilt, requiring replacement of the hinge, resulting in high maintenance costs and difficulty. Therefore, those skilled in the art have provided a washing machine door hinge assembly to solve the problems mentioned in the background art. Utility Model Content

[0004] The purpose of this utility model is to provide a washing machine door hinge assembly to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A washing machine door hinge assembly includes a fixing component and an adjusting component. The adjusting component is located at the front end of the fixing component.
