The invention discloses portable roller skates. The upper part, the left side and the right side of each roller skate are fixed, and the lower part of each roller skate consists of two bottom plates and 4 wheels; every two bottom plates are respectively connected with the bottom of the left side and the bottom of the right side of the surface of one corresponding roller skate, and can respectivelyrotate in the vertical direction around the bottom of the left side and the bottom of the right side; every two bottom plates are connected with a corresponding lifting plate on the surface of the corresponding roller skate through a corresponding bended connecting rod; the outer side of each lifting plate is connected with a corresponding fixed lifting rod; a plurality of protrusions of which the upper parts are small and the lower parts are large and which are vertically and continuously arrayed are arranged on the outer side close to the top of each lifting rod; each lifting rod is arranged in a corresponding sleeve; each sleeve is connected with and fixed to the surface of the corresponding roller skate; a protrusion of which the upper part is small and the lower part is large is arranged on the outer side of the top of the inner wall of the corresponding sleeve; a spring shim is arranged on the inner side close to the top, of the inner wall of the corresponding sleeve; and each lifting rod is arranged between the corresponding protrusion on the inner side of the corresponding sleeve and the corresponding spring shim, and is in vertical up-and-down movement. The roller skatesdisclosed by the invention also have the functions of braking and merging after the roller skates are put off, and putting off and putting on can be performed instantly; the safety is good; the rollerskates are adapted to different terrains and different occasions, so that a user is assisted to trip conveniently and exercise; and the roller skates are energy-saving, environmentally friendly, freefrom release and free from pollution.

Description

technical field [0001] The invention relates to a convenient roller skate. Background technique [0002] Roller skates are a very efficient means of transportation, with light equipment and fast speed. The principle is to use rolling friction to convert the work done by the user's body twisting into kinetic energy to the greatest extent, so as to achieve the purpose of walking instead of fitness. But if the road is not very smooth, the speed is slower than walking, and there is a risk of slipping. The roller skates on the market are not easy to take off, the braking distance is long, and the braking is not easy to control, which poses a safety hazard. These are the reasons why roller skates are not commonly used in cities. Invent a roller skate that can be put on the user's shoes and can be taken off instantly to ensure the safety of the user without affecting the appearance of wearing and matching, and to adapt to different terrains and occasions.
