In an embodiment of the present invention, referring to fig. 1 to 4, a handle resetting damping structure, specifically, a body 1000, a handle 2000, a rotation shaft 3000 and a damping device 4000, wherein rotation shafts 3000 are disposed at two ends of the handle 2000, the rotation shaft 3000 is rotatably connected to the body 1000, and at least one rotation shaft 3000 is connected to the damping device 4000, wherein the damping device 4000 includes a connection seat 4100 and an elastic member 4200, the connection seat 4100 is disposed on the body 1000, a holding hole 4110 is disposed at an upper end of the connection seat 4100, and the holding hole 4110 forms a resistance to rotation of the rotation shaft 3000 corresponding to the rotation shaft 3000 passing through the holding hole 4110, and an inner wall of the holding hole 4110 forms a rotation resistance of the rotation shaft 3000; the elastic element 4200 is disposed on one side of the connecting seat 4100, the protrusion 3100 is disposed on the shaft 3000, and the protrusion 3100 presses the elastic element 4200 to be elastically deformed when the shaft 3000 rotates. Specifically, when the body 1000 is lifted, the damping device 4000 generates resistance to the handle 2000, the body 1000 is prevented from shaking to cause collision between an object in the body 1000 and the body 1000 when the body is walking, the body 1000 and the object are damaged, when the handle 2000 is put down, the handle 2000 slowly descends under the action of the damping device 4000 when the handle 2000 is reset, and abnormal sound and damage to the body 1000 caused by smashing of the handle 2000 are avoided. The handle 2000 reset damping structure can effectively protect the body 1000 and objects in the body 1000, and is simple, convenient and intelligent to operate. More specifically, the grip hole 4110 applies resistance to the rotating shaft 3000, and when the handle 2000 is lifted, the elastic member 4200 and the grip hole 4110 generate resistance to the rotating shaft 3000, so that the handle 2000 is slowly lifted. When the handle 2000 is released, the elastic element 4200 deforms to generate power for the convex portion 3100 on the rotating shaft 3000, and the handle 2000 is driven to move to the initial position; the clasping hole 41110 applies resistance to the rotating shaft 3000, so that the handle 2000 is prevented from rapidly descending and excessively colliding with the body 1000. And when the body 1000 is lifted up, the problem that the body 1000 shakes back and forth can be effectively prevented by the damping device 4000.

Still further, referring to fig. 1, the rotating shafts 3000 at both ends of the handle 2000 are connected to a damping device 4000. In this embodiment, the damping devices 4000 are disposed at both ends of the rotating shaft 3000, so as to avoid the problem of jamming or unbalanced stress on the handle 2000.

Further, referring to fig. 3, one side of the clasping hole 4110 is an opening structure, two sides of the opening extend outward to form a connecting portion 4111, and a locking screw is connected to the two connecting portions 4111. In the embodiment, the two connecting parts are connected through the screws, so that the assembly is convenient; the resistance of the locking hole 4110 to the rotating shaft 3000 can be increased or reduced through the adjusting screw, so that the phenomenon that the rotating shaft 3000 is blocked due to too large resistance or cannot play a damping role due to too small resistance is avoided.

Further, referring to fig. 1 and 2, the elastic element 4200 is a resilient sheet 4420 structure 4300, one end of the elastic element 4200 is fixed on the connection seat 4100, the other end is tilted upward to form a tilted portion 4310, and the rotation shaft 3000 rotates to make the protrusion 3100 press the tilted portion 4310. In this embodiment, when the handle 2000 is lifted upwards, the rotating shaft 3000 rotates, the protrusion 3100 presses the tilting portion 4310, the tilting portion 4310 generates a restoring elastic force on the rotating shaft 3000, and when the suitcase is not subjected to an external force, the restoring elastic force generates a restoring force on the rotating shaft 3000 to drive the handle 2000 to return to the initial position.

Further, referring to fig. 1 and 4, a connecting pin 3200 is further provided on the rotating shaft 3000; the damping device 4000 further comprises an elastic reset mechanism 4400, wherein the elastic reset mechanism 4400 comprises a mounting seat 4410, an elastic sheet 4420, a positioning shaft 4430 and a compression spring 4440; the mounting seat 4410 is disposed on the body 1000 and located at one side of the rotation shaft 3000; the positioning shaft 4430 is arranged on one side of the mounting seat 4410 far away from the rotating shaft 3000; one end of the elastic sheet 4420 is provided with a bending part bent downwards, the other end is provided with a connecting hole 4422, the bending part is provided with a guide hole 4421, the connecting hole 4422 is connected with a connecting pin, and the guide hole 4421 is sleeved on the positioning shaft 4430 in a sliding manner; the compression spring 4440 is sleeved on the positioning shaft 4430 and located between the bending part and the mounting seat 4410. In this embodiment, when the rotating shaft 3000 rotates, the rotating shaft 3000 drives the elastic piece 4420 to move, the bending portion of the elastic piece 4420 presses the compression spring 4440, the compression spring 4440 generates elastic deformation, and the elastic piece 4420 is deformed into an arc shape around the rotating shaft 3000; so that the compression spring 4440 and the elastic sheet 4420 are charged; when the handle is released, the stored energy of the compression spring 4440, the elastic piece 4420 and the elastic piece 4200 is released to the rotation shaft 3000, so that the rotation shaft 3000 is returned to the initial state by the elastic restoring force.

Further, a limiting piece is disposed at a free end of the positioning shaft 4430 for limiting the bending portion of the elastic piece 4420. In this execution, play spacing effect to the shell fragment through the locating part, avoid the shell fragment from locating shaft landing. More specifically, the limiting part is a screw, the screw is connected to the end of the positioning shaft, and the head of the screw is used for blocking the bending part of the elastic sheet.
