Traceless caster with good mute buffering performance
This utility model discloses a silent, non-marking caster with good cushioning performance. It includes a bracket, which comprises a top plate and two arm plates fixed to the left and right ends of the lower side of the top plate. A mounting plate is rotatably mounted on the upper side of the top plate. A forward-extending arm plate is hinged to the lower end of each of the two arm plates. The rear ends of the two arm plates are fixedly connected by a connecting plate to form a bracket. A roller is rotatably mounted on the inner front end of the two arm plates via a wheel axle assembly. The roller includes a hub and a tire fitted onto the outer circumferential side of the hub. The tire is made of a flexible polymer material. A longitudinal shock-absorbing component is provided between the front end of the arm plate and the front end of the top plate. The caster exhibits excellent shock absorption and cushioning performance during load-bearing movement. During load-bearing movement, the elastic deformation of the tire can mitigate the instantaneous impact of the caster on the ground. The tire can also maintain friction while making flexible contact with the ground, avoiding hard scraping and tire wear. It also provides quiet operation and leaves no marks.
