The invention relates to the technical field of travel suitcases, and discloses a travel suitcase retractable universal wheel which comprises a triggering mechanism and a supporting mechanism, a guide column is arranged in the supporting mechanism, the outer surface of the guide column is movably connected with a compression spring, and the left end of the guide column is fixedly connected with a limiting block. A clamping block is movably connected to the left end of the guide column and located at the lower end of the limiting block, an anti-resistance spring is fixedly connected to the left end of the clamping block, and a supporting block is fixedly connected to the lower end of the guide column. The force for pushing the clamping blocks to resist the resistance springs through the guide columns is enough to compress the resistance springs, so that when the clamping blocks move leftwards, the guide columns move downwards, then the supporting blocks are driven to move downwards, and in the process that the sliding wheels move upwards and the supporting blocks move downwards, the sliding wheels on the suitcase are evenly distributed at the bottom of the suitcase; therefore, when the distance of the upper end of the suitcase is too large, the universal wheels at the lower end of the suitcase automatically contract to decompose pressure.

    本发明涉及旅行箱技术领域,且公开了一种旅行箱可收缩万向轮,包括触发机构和支撑机构,所述支撑机构内部包括导柱,所述导柱外表面活动连接有压缩弹簧,所述导柱左端固定连接有限位块,所述导柱左端且位于限位块下端活动连接有卡接块,所述卡接块左端固定连接有抗阻弹簧,所述导柱下端固定连接有支撑块。通过导柱推动卡接块对抗阻弹簧的力足够压缩抗阻弹簧,从而使得卡接块向左移动时,使得导柱向下移动,进而带动支撑块也向下移动,从而在滑轮向上移动,支撑块向下移动的过程中,使得旅行箱上的均匀分布在旅行箱底部,从而到达当旅行箱上端离过大时,旅行箱下端万向轮自动收缩分解压力的效果。
