The case body 10 and the cap 20 are rotatably coupled by the hinge 30, and the hinge 30 can stably support the cap 20 when the case is opened by the cap 20.

As shown in fig. 2 to 7, the hinge 30 includes a shaft member 1, a connecting rod 2, a crankshaft 3, and a lock mechanism 4. The shaft element 1 comprises a first shaft 11, a support element 12 and a second shaft 13, the support element 12 is fixed on the first shaft 11, the second shaft 13 is rotatably connected with the support element 12, the first shaft 11 and the second shaft 13 are parallel and arranged at intervals, and the first shaft 11 is fixed on the box body 10 and is rotatably connected with the box cover 20; the connecting rod 2 is rotatably disposed on the second shaft 13, the crankshaft 3 is rotatably connected to the connecting rod 2, the crankshaft 3 is rotatably connected to the box cover 20, and the crankshaft 3 is parallel to and spaced from the center of rotation of the box cover 20 and the centers of rotation of the crankshaft 3 and the connecting rod 2, so that the box cover 20 can rotate relative to the box body 10 via the first shaft 11 to open or close the box body 10. During the rotation of the box cover 20 relative to the box body 10, the box cover 20 can drive the crankshaft 3 and the connecting rod 2 to rotate, and the connecting rod 2 and the crankshaft 3 can rotate relatively. Specifically, the crankshaft 3 can rotate relative to the connecting rod 2 to have a first position and a second position, and when the crankshaft 3 is located at the first position, the box cover 20 covers the box body 10; when the crankshaft 3 is located at the second position, the box cover 20 opens the box body 10, and the locking mechanism 4 can lock the relative positions of the connecting rod 2 and the crankshaft 3 so as to keep the position of the box cover 20 at the position where the box body 10 is opened, so that a better supporting effect is achieved; compared with a torsion spring type structure in the prior art, the torsion spring type structure is easy to assemble; compared with a double-shaft structure in the prior art, the assembling tolerance requirement is lower, and the matching degree of the assembled box body 10 and the assembled box cover 20 can be ensured.

In the present embodiment, the elastic protrusion 45 is provided on the crankshaft 3, and the first limit groove 44 is provided on the connecting rod 2.

Optionally, the connecting rod 2 includes a rod portion 22 rotatably connected to the second shaft 13, a first clasping member 23 disposed at one end of the rod portion 22, and a second clasping member 24 connected to the first clasping member 23, the first clasping member 23 and the second clasping member 24 are detachably connected and enclosed to form a through hole 25, and the crankshaft 3 is rotatably disposed through the through hole 25, so as to facilitate assembly and maintenance of the connecting rod 2 and the crankshaft 3.
