AI Technical Summary
The installation method of existing washing machine lids is complicated, requiring horizontal axis positioning and damping assistance, resulting in a complex structure.
It adopts a positioning resistance hinge structure, including a housing, spring and pivot, and limits the pivot angle through a limiting component, eliminating the horizontal axis mechanism, and combining hinge and assist function.
The simplified installation structure and assist function ensure that the cover is stably positioned at a specified angle, avoiding excessive opening and closing and improving ease of use.

Abstract
Claims
1. A position-limiting resistance hinge, characterized in that, The device includes a housing, a spring, and a rotating shaft. The housing has a storage cavity inside, and an end cap is fixedly mounted on the surface of the housing corresponding to the storage cavity. The rotating shaft is rotatably connected to the end cap, with one end of the rotating shaft extending out of the housing. The spring is disposed inside the storage cavity, with one end of the spring fixedly connected to the inside of the housing and the other end of the spring fixedly connected to the rotating shaft. The angle of rotation of the rotating shaft is limited by a limiting component between the rotating shaft and the end cap.
2. A resistance positioning hinge as claimed in claim 1, characterized in that The storage cavity is equipped with a positioning post, and a slot is formed in the middle of the positioning post. The other end of the rotating shaft extends into the storage cavity and is provided with a slot. The two ends of the spring are respectively sleeved on the surface of the positioning post and the rotating shaft, and the ends of the spring can be easily inserted into the slot and the slot to form a fixed connection.
3. A resistance positioning hinge as claimed in claim 1, characterized in that The housing has a rectangular structure, the storage cavity is located on one side of the housing, and the end of the rotating shaft extending out of the housing has a flat section.
4. A resistance positioning hinge as claimed in claim 1, characterized in that The limiting component includes a fixed boss provided at one end of the end cap near the housing. The housing has a limiting groove corresponding to the fixed boss, and the fixed boss is engaged in the limiting groove. A first limiting boss is fixedly provided near the surface of the rotating shaft of the fixed boss. A rotational gap is formed between the rotating shaft and the fixed boss through the first limiting boss. A second limiting boss is fixedly provided on the surface of the rotating shaft corresponding to the rotational gap. The second limiting boss can rotate along the rotational gap. The first limiting boss is used to limit the rotation angle of the second limiting boss.
5. A resistance positioning hinge as claimed in claim 4, characterized in that The end cap has a groove on the side near the housing, forming a stepped structure, and the fixing boss is disposed in the groove.
