Description

Technical Field

[0001] The utility model mainly relates to the technical field of bicycles, in particular to a bicycle parking rack. Background Art

[0002] Green travel is one of the themes of green environmental protection. As a short-distance transportation tool, bicycles have the advantages of convenient personal travel, energy saving, no pollution, and low manufacturing and maintenance costs. It has become an important way of travel. With the large-scale promotion of shared bicycles, a series of parking problems have been brought about. Random parking not only affects people's use of space, but also affects people's living environment. On the other hand, bicycles used by ordinary families or bicycles placed in bicycle shops will waste a lot of space if they are placed directly.

[0003] The prior art realizes upright parking of bicycles by using a stand with a fixed end and a telescopic end, a bottom frame with a wheel groove, and a hook arranged on the stand. However, the stand cannot adjust the stand height to suit the size of the bicycle. If the bicycles are of different sizes, the rear wheel of the bicycle may easily fall off the parking stand or the rear wheel may easily go over the bottom frame and cause the bicycle to tip over.

[0004] However, the chassis forms a T-shaped structure through the crossbeam and longitudinal beam, and the side support is unstable and prone to rollover. In addition, the vertical frame is a vertical tubular structure and lacks a limit support component for the rear wheel. The rear wheel can easily pass over the chassis and cause a rollover.

[0005] However, it lacks a limiting structure for the rear wheel of the bicycle in the rolling direction and the circumferential direction of the wheel, so the rear wheel of the bicycle is easy to leave the parking rack, and the parking stability of the bicycle is insufficient.

[0006] Most similar stands on the market have their uprights set in the middle of the beam and cannot accommodate bicycles with racks. Utility Model Content
