Description

Technical field [0001] The present invention relates to the technical field of the trunk, and is specifically that a wheel can be collapsed. Background technique [0002] The suitcase, also known as the suitcase, trolley case, is a tab that is taken to place items when it is a type of baggage. Usually the suitcase is used to place the clothes, personal care products and souvenirs required. The size of the suitcase on the market is generally based on the vehicle (portable baggage) of the Airlines (Portable Luggage) and the shipping box (the mail baggage) size specified by the airline (International Air Transport Association). [0003] However, the sliding rollers at the bottom of the traditional suitcase are generally fixed in the surface of the suitcase, which cannot be expanded or collapsed, and it is easy to slide on public vehicles such as subway, while doing noise and vibration when walking on both sides of the road or other uneven roads. Great. The folding wheel structure in...

Problems solved by technology

[0003] However, the sliding rollers at the bottom of the traditional suitcase are generally fixed on the surface of the suitcase, and cannot be retracted or folded. They are easy to slide on public transportation such as subways, and at the same time make noise and vibration when walking on blind roads on both sides of the road or other uneven roads. very big

In the existing invention patents, the folding wheel structure is complicated, and it is unfolded on the side of the suitcase, and the suitcase needs to be tilted at a large angle to be used; the suitcase that uses hinges to realize the folding of the wheels is inconvenient to use and has low connection strength and takes up space big and ugly
