Abstract
Description
Technical Field
[0001] This utility model belongs to the field of subway hanging ring technology, and in particular relates to a combined subway hanging ring. Background Technology
[0002] A subway is a high-speed, high-capacity, electrically powered rail transit system built in cities. Trains run on fully enclosed tracks. Lines in urban centers are primarily located underground tunnels, while lines outside urban centers are generally located on elevated bridges or at ground level. Subways are a high-density, high-capacity urban rail transit system encompassing various underground and above-ground sections of the city. In Taiwan, subways are called "MRT" (Mass Rapid Transit). Subways typically have multiple sets of handrails inside, which not only increase passenger capacity but also prevent passengers from falling.
[0003] The existing technology still has the following shortcomings:
[0004] The handles in existing subway handrails are mostly one-piece closed ring structures. During use, the user's hand may get stuck in the handrail. The current solutions are either to apply lubricant to the hand or to break the handle. Of the two methods, applying lubricant is inconvenient, while breaking the handle requires replacing the entire handrail. In addition, the height of existing subway handrails is fixed, which limits the range of people who can use them and makes them highly limited and impractical. Utility Model Content
