[0002] With the high-speed development of traffic, the number of people traveling is increasing, and all kinds of bags have become a tool for carrying personal items such as personal belongings and clothes. With the continuous improvement of people's living and consumption levels, Higher requirements are put forward for the appearance, structure and performance of the bags. The existing common bags are equipped with pull rods and rollers at the bottom. The pull rods pull the box to make the luggage roll forward under the action of the rollers, thus saving people. physical strength, which facilitates the transportation of luggage, and with the increase in the number of uses, a greater test is put forward for the wear resistance of the wheels. The wheels of the existing luggage are prone to noise when rotating, and they are not flexible when rotating. To solve the existing defects, it is necessary to propose a luggage universal wheel with flexible rotation, no noise and reliable performance to solve the above-mentioned needs
