And a damping opening and closing device for pivotally connecting the box body and the cover body, wherein the pivotal portion of the box body and the cover body is provided with a coaxial recessed hole, so that the damping opening and closing device is inserted and fixed in the two recesses Between the holes, the damping opening and closing device includes an inner rotating body, an outer rotating body, a torsion spring fixed between the inner and outer rotating bodies, and a clamp. The damping layer provided between the inner swivel body and the peripheral wall of the outer swivel body, when the cover body is opened, is simultaneously opened by the elastic force of the torsion spring and the damping damping effect of the damping layer to avoid sudden Open. Sovereignty item 1. A cushioned openable box including a box body and a cover body, wherein the box body and the cover body are provided with a convex and a concave joint and a pivotal part pivoted to each other, relative to the other end of the pivot joint part. Then, there are buckled parts that are interlocked with each other, characterized in that: coaxial holes are arranged between the two pivotal connections; and a damping opening and closing device is arranged, which includes an inner rotating body and an outer rotating body. The body, a torsion spring and a damping layer, wherein the inner and outer rotating bodies are opposite to each other, and are in an inner and outer joint shape; and the damping layer is disposed on the periphery of the inner and outer rotating bodies nested with each other. And the torsion spring is inserted between the inner and outer rotating bodies, and the two ends of the torsion spring are respectively fixed at the bottom of the inner rotating body and the outer rotating body, and the inner and outer rotating bodies are put on each other. In the two recessed holes combined, the inner and outer rotating bodies are provided with locking parts that are concave-convexly engaged with each other and away from the ends of the grooves.
