Two through holes 614 are vertically and oppositely formed on the extension shaft 613, and the two through holes 614 are respectively connected with the two hooks 41. In use, the hexagonal prism 612 is rotated by the adjusting wheel 64 to drive the entire hinge shaft connecting rod 61 to rotate, and the rotation of the reset shaft 4 is driven by the connection between the through holes 614 and the hooks 41.

[0038] As the preferred of the embodiment, the adjusting structure 6 further comprises an adjusting screw fixing plate 62 fixed on the door frame 1, an adjusting screw rod 63 threadedly connected with the adjusting screw fixing plate 62, and a connecting head 631 integrally formed at the inner end of the adjusting screw rod 63. The outer end of the adjusting screw rod 63 is located in the adjusting hole 11 and is provided with a cross-shaped groove 630 for easy screwing. When adjusting the adjusting wheel 64, the adjusting screw rod 63 is rotated by a cross screwdriver or a straight screwdriver, and the adjusting screw rod 63 is extended and retracted on the adjusting screw fixing plate 62 during rotation, thereby driving the adjusting wheel 64 to rotate through the connection between the connecting head 631 and the connecting sliding groove 644.

[0039] It should be noted that the adjusting screw fixing plate 62 is sleeved on the hinge shaft connecting rod 61 and located above the outer convex ring 611. The adjusting wheel 64 is provided with a limiting hole 642 for the hexagonal prism 612 to pass through, and the adjusting wheel 64 is located below the outer convex ring 611. The outer convex ring 611 can well limit the position of the hinge shaft connecting rod 61.

[0040] As the preferred of the embodiment, an arc-shaped driving plate 643 is integrally formed on the outer wall of the adjusting wheel 64. The arc-shaped driving plate 643 is provided with a sliding connection sliding groove 644 on the inner wall.

[0041] As the preferred of the embodiment, a connecting block 65 fixed on the door frame 1 is arranged below the adjusting wheel 64, and the adjusting wheel 64 is rotationally connected to the connecting block 65. The connecting block 65 can increase the stability of the adjusting wheel 64.

[0042] As the preferred of the embodiment, a lower hinge 5 fixed on the bottom of the door frame 1 and used for limiting the rotation of the hinge shaft connecting rod 61 is further included. The lower hinge 5 is provided with a positioning hole 50 for the hexagonal prism 612 to pass through. It should be noted that the lower hinge 5 is fixed on the cabinet body on which the door frame 1 is installed by bolts, and the door body mechanism is installed in the last installation structure. When adjusting the tightness, it is the first structure to be disassembled.

[0043] The self-resetting door body structure with visual scale mark and adjustable tightness in the application is used as follows: first, the door frame 1 is fixed on the cabinet body, then the opening tightness of the door body 2 is adjusted, in the adjustment, the adjusting screw rod 63 is rotated by the cross screwdriver or the straight screwdriver, the adjusting screw rod 63 is telescopic on the adjusting screw fixed plate 62 in the rotation, then the adjusting wheel 64 is rotated by the connection between the connecting head 631 and the connecting sliding groove 644, the hexagonal prism 612 is rotated by the adjusting wheel 64, then the whole hinge shaft connecting rod 61 is rotated, the reset shaft 4 is rotated by the connection between the perforation 614 and the hook 41, after the reset shaft 4 is rotated, the fitting force between the door body 2 and the door frame 1 is changed, the strength required to open the door body 2 is changed.
