Detailed Implementation

[0018] like Figs. 1 to 5 As shown, an adjustable-angle lifting cam structure includes a mounting base plate 10, a mounting upper plate 20, and a lifting assembly 30. The lifting assembly 30 is adjustablely installed between the mounting base plate 10 and the mounting upper plate 20. In use, the mounting base plate 10 is installed at the bottom of the frame, and the mounting upper plate 20 is installed at the bottom of the door panel. By rotating the lifting assembly 30, the angle of the mounting upper plate 20 can be changed, thereby adjusting the angle of the door. At the same time, the rotation of the lifting assembly 30 can also move the mounting upper plate 20 up and down to adjust the height of the door. This design allows users to fine-tune the vertical position of the door during use, ensuring smoothness and sealing when the door is opened and closed.

[0019] In practical implementation, the lifting assembly 30 includes a first adjusting cam 31, a second adjusting cam 32, and a cam connecting pin 33.
