[0004] In order to solve the above technical problem, the luggage damper caster of the utility model comprises a connecting member connected to the main body of the luggage, wherein a supporting portion is provided below the connecting member, the upper part of the supporting portion is connected with the connecting member through a supporting shaft, the lower part of the supporting portion is pivotally connected with a swingable bracket, a first axle and a second axle are provided on both sides of the bracket, respectively, a first wheel and a second wheel are installed on the first axle and the second axle, and an elastic mechanism is installed between the bracket and the supporting portion to enable the included angle therebetween to be in the maximum state.

[0005] The bracket is provided with a connecting block, both sides of the connecting block are provided with a first pivoting shaft and a second pivoting shaft connected with the supporting portion, respectively, the elastic mechanism comprises a first torsional spring and a second torsional spring installed on the first pivoting shaft and the second pivoting shaft, respectively, one end of the first torsional spring and the second torsional spring is fixed to the bracket, and the other end of the first torsional spring and the second torsional spring is fixed to the supporting portion. The elastic mechanism is simple in structure and easy to implement, and is installed on both sides, respectively, so that the damping effect of the product is more balanced.

[0006] The lower part of the supporting portion is provided with a first wing edge and a second wing edge, the first wing edge and the second wing edge are provided with a first shaft hole and a second shaft hole correspondingly matched with the first pivoting shaft and the second pivoting shaft, respectively, both ends

Description of the first wing edge and the second wing edge are provided with an arcuate convex surface, and the bracket is provided with an arcuate cavity correspondingly matched with the arcuate convex surface. This structure is beneficial for the bracket to be damped and oscillated, and the first wing edge and the second wing edge have a good sealing effect to prevent the entry of debris.

[0007] The bracket and the supporting portion are provided with a first positioning hole and a second positioning hole into which both ends of the first torsional spring and the second torsional spring are inserted to facilitate quick installation of the torsion springs.

[0008] A positioning ring is provided in the middle of the supporting shaft, and a cavity into which the positioning ring is embedded is provided at the top of the supporting portion. The lower part of the supporting shaft is provided with an axial positioning edge, an elongated groove correspondingly matched with the positioning edge is provided inside the supporting portion, the upper part of the supporting shaft is provided with an annular groove, and a clamp spring which fixedly connects the supporting shaft and the connecting member is installed in the annular groove. The above-mentioned installing structure enables the supporting shaft to be well positioned, so that the overall structure of the product is more stable and has better impact resistance.

[0009] The utility model has the beneficial effect that in the structure of the luggage damper caster, the supporting portion and the bracket are connected by the elastic mechanism, which can achieve a good damping effect by the rotation of the bracket relative to the supporting portion and is beneficial for protecting the luggage and contents in the luggage.
