Abstract

The invention discloses an anti-noise luggage case, which comprises a box body and an accommodating cavity formed in the box body, wherein a plurality of wheel cavities are formed in the bottom of thebox body, the two symmetrical side walls of each wheel cavity are each fixedly connected with a connecting pipe, each connecting pipe is sleeved with a rotating shaft, the rotating shaft is connectedwith a roller through a flat key in an interference fit mode, the connecting pipe is provided with a circulating cavity in a communicating mode, the circulating cavity and the connecting pipe jointlyform a circulating flowing channel, the flowing channel is filled with water, the bottom of the circulating cavity is fixedly connected with a compression spring, and the top of the compression spring is fixedly connected with a rack. The anti-noise luggage case has the advantages that the rotating shaft swings left and right irregularly, the half gear and the roller rotate at the same time, therack and the sealing block reciprocate, the liquid in the flowing channel circularly flows under the action of the liquid flowing opening in the sealing block and the one-way valve, and the effect ofreducing solid propagation generated when the roller passes to generate noise can be achieved in the process.

Description

technical field [0001] The invention relates to the technical field of luggage, in particular to a noise-proof luggage. Background technique [0002] Suitcases are essential props for long-distance travel and business trips in people's lives. They are convenient for loading personal items and carrying them with you. When in use, due to their heavy weight, they need to be dragged by hand rods and rollers. [0003] In actual use, due to the different conditions of the external road surface, during the towing process, especially in the state of uneven ground, due to the multiple collisions between the rollers and the ground, there will be a lot of noise during towing, and it is used by a large number of people. Occasions and environments, such as when students enroll in school and airports and train yards will cause greater noise impact on the surrounding environment, and at the same time will also cause greater disadvantages to themselves. Based on this, the present invention ...
