Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all the other embodiments obtained by the ordinary skilled in the art without creative labor belong to the scope of protection of the utility model.

[0024] Please refer to Figures 1-7 The utility model provides a technical scheme, a novel gravity regression hinge, the hinge lower part 1 includes the bottom plate piece 1.1, the core shaft 1.2 of bottom end vertical fixed sleeve set in the middle part of one end of bottom plate piece 1.1 and the first and last two lower arc-shaped sliding blocks 1.3 of fixed in the top surface and the outer peripheral wall of core shaft 1.2, the end of bottom plate piece 1.1 away from core shaft 1.2 is equipped with fixed hole 1.1.1, the position between the end of two lower arc-shaped sliding blocks 1.3 of bottom plate piece 1.1 is equipped with lower avoiding hole 1.1.2, the top surface of lower arc-shaped sliding block 1.3 is sequentially equipped with lower helical slope 1.3.1, lower support plane 1.3.2 and lower stop block 1.3.3.

[0025] The hinge upper part 2 includes the top plate piece 2.1, the sleeve ring 2.2 of fixed sleeve set in the middle part of one end of top plate piece 2.1 and with the rotation sleeve joint matching of core shaft 1.2 and the first and last two upper arc-shaped sliding blocks 2.3 of fixed in the bottom surface of top plate piece 2.1 and located in the outer edge of sleeve ring 2.2, the middle part of one end of top plate piece 2.1 away from sleeve ring 2.2 is equipped with fixed groove 2.1.1, the position between the end of two upper arc-shaped sliding blocks 2.3 of top plate piece 2.1 is equipped with upper avoiding hole 2.1.2, the bottom surface of upper arc-shaped sliding block 2.3 is sequentially equipped with upper helical slope 2.3.1, stop groove 2.3.2 and upper support plane 2.3.3, the outer edge of upper support plane 2.3.3 bottom surface and one end close to stop groove 2.3.2 is equipped with upper stop block 2.3.4.

[0026] In summary, the hinge lower part 1 is fixed at the bottom corner of the door frame, and the hinge lower part 1 is fixed at the end of the bottom surface of the door body.
