[0028] To make the objectives, technical solutions, and advantages of the present utility model clearer, the following will further describe the embodiments of the present utility model with reference to the drawings.

[0029] As Figure 1 , Figure 2 , Figure 3 and Figure 4 shown, the present utility model also discloses a stationery box according to an embodiment, which includes a box body 10, a cover body 20, a switch assembly 30, and a damping rotating shaft 40. The cover body 20 is covered on the box body 10.

[0030] The switch assembly 30 is respectively connected to the box body 10 and the cover body 20, and the switch assembly 30 can be operated to achieve snap connection and snap disconnection with the box body 10 and the cover body 20.

[0031] One side end of the box body 10 is rotatably connected to one side end of the cover body 20 through the damping rotating shaft 40. The damping rotating shaft 40 includes a main body 41, a damping member 43, an elastic member 45, and a rotating member 47.

[0032] One end of the damping member 43 is rotatably connected to one end of the main body 41, one end of the rotating member 47 is rotatably connected to the other end of the main body 41, and one end of the rotating member 47, the elastic member 45 and the other end of the main body 41 are connected in sequence.

[0033] When the cover body 20 covers the box body 10, the box body 10 and the cover body 20 are snap-connected, and at this time, the elastic member 45 undergoes elastic deformation, so that the cover body 20 has a tendency to rotate and open relative to the box body 10.

[0034] The damping rotating shaft 40 of this stationery box of the present utility model has a simple structure. Only two parts, namely the main body 41 and the damping member 43, are required to achieve the function of damping rotation, thereby avoiding the impact force on the stationery box caused by the mechanical movement inertia after the cover body 20 rotates and opens relative to the box body 10. Compared with the traditional damping rotating shaft with a complex structure, the damping rotating shaft 40 of this stationery box of the present utility model has a simple structure, so it is extremely simple to assemble. The volume of the damping rotating shaft 40 can be designed to be small, so that it can be applied to the stationery box.

[0035] Specifically, when the cover body 20 covers the box body 10, the user operates to release the snap connection between the box body 10 and the cover body 20. At this time, due to the tendency of the cover body 20 to rotate and open relative to the box body 10, the cover body 20 rotates relative to the box body 10. Under the action of the damping rotating shaft 40, the cover body 20 rotates slowly relative to the box body 10, thereby realizing the opening of the stationery box.

[0036] In this embodiment, the switch assembly 30 can be of any structure, as long as it can achieve the snap connection and disconnection between the box body 10 and the cover body 20 under operation.

[0037] For example, the switch assembly 30 can include a snap member and a card slot that are snap-connected to each other, and the two are respectively connected to the box body 10 and the cover body 20. The user can manually achieve the snap connection and disconnection between the snap member and the card slot, thereby realizing the snap connection and disconnection between the box body 10 and the cover body 20. The snap member can be of a push-type structure, and by pressing the snap member, the snap connection between the box body 10 and the cover body 20 can be released.

[0038] Combined with the drawings, preferably, in this embodiment, one end of the main body 41 is provided with a first receiving groove 411 that matches the damping member 43. One end of the damping member 43 is inserted into the first receiving groove 411. The damping member 43 is rotatably connected to the main body 41. The damping member 43 and the area near the opening of the first receiving groove 411 are hermetically connected, so as to seal the first receiving groove 411, and the first receiving groove 411 is filled with damping oil.

[0039] Specifically, when the main body 41 rotates relative to the damping member 43, the damping oil between one end of the damping member 43 and the first receiving groove 411 functions as damping, thereby achieving damping rotation.

[0040] Combined Figure 5 , more preferably, in the present embodiment, a columnar protrusion 412 is provided at the bottom of the first receiving groove 411, and a second receiving groove 431 matching the columnar protrusion 412 is provided at one end of the damping member 43.

[0041] When one end of the damping member 43 is inserted into the first receiving groove 411, the columnar protrusion 412 is received in the second receiving groove 431, and the first receiving groove 411 and the second receiving groove 431 communicate with each other.

[0042] Specifically, when the main body 41 rotates relative to the damping member 43, the damping oil between the columnar protrusion 412 and the second receiving groove 431 also functions as damping, thereby achieving damping rotation.

[0043] In the present embodiment, a through hole 432 is provided on the side wall of the second receiving groove 431, and the through hole 432 communicates the first receiving groove 411 and the second receiving groove 431.

[0044] The through hole 432 provided on the side wall of the second receiving groove 431 communicating the first receiving groove 411 and the second receiving groove 431 can enable better exchange of the damping oil between the first receiving groove 411 and the second receiving groove 431, and avoid excessive resistance caused by the damping oil pressure during rotation.

[0045] Combined Figure 5 , in the present embodiment, there is a first gap (not marked in the figure) between the outer side wall of one end of the damping member 43 and the side wall of the first receiving groove 411, and a second gap (not marked in the figure) between the outer side wall of the columnar protrusion 412 and the side wall of the second receiving groove 431.

[0046] Both the first gap and the second gap are filled with damping oil, which not only plays a lubricating role but also provides a certain amount of resistance.

[0047] Combined Figure 5 , in the present embodiment, there is a first interval 413 between the end of one end of the damping member 43 and the bottom of the first receiving groove 411, and a second interval 433 between the bottom of the second receiving groove 431 and the end of the columnar protrusion 412.

[0048] Both the first interval 413 and the second interval 433 are filled with damping oil, which can further enable better exchange of the damping oil between the first receiving groove 411 and the second receiving groove 431, and avoid excessive resistance caused by the damping oil pressure during rotation.
