Abstract
The utility model relates to a damping device of a baby trammer, which comprises an upper support (1), a lower support (4), a damping spring (2) and a center pole (3), wherein the center pole is inserted in the axial through hole of the lower support from the lower end of the lower support, and is inserted in the axial round hole on the center of the upper support after threading through the damping spring. The upper end of the center pole is screwed in a screw cap (5) in a square concave portion on the upper support, and the expanded portion (8) on the lower end of the center pole is pressed with a step (13) in the axial through hole of the lower support. The damping device of a baby trammer is arranged between a side bar of a bicycle basket of the baby carrier and a frame of the baby trammer, and when the baby carrier is shocked, since the damping spring is compressed, the impact force which is generated by vibration is absorbed, and the shock-absorbing function is played. The damping spring is tensed by the center pole in the damping device of the baby trammer, which is led to get a certain precompression, and the spring is led to be in a correct elastic state, which can not be over soft and gets more suitable damping property.
