Description

Technical Field

[0001] The invention relates to the technical field of bicycle racks, and in particular to a tiltable bicycle rack. Background Art

[0002] With the improvement of social and economic level, the popularity of family cars has also greatly increased. Many families often install luggage racks on their cars when traveling or exercising to carry some luggage, sports equipment, etc. However, most of the existing luggage racks are fixed on the roof of the car, which is very inconvenient to use to load bicycles. When people need to carry bicycles, they usually choose folding bicycles, or put the front wheel or rear wheel of the bicycle in the trunk of a three-compartment car, and the other part extends out of the car. This is not only unsafe, but also often worried that the bicycle will be thrown out of the car. For this reason, some people in the industry have involved in vehicle-mounted bicycle racks, which are specifically used to carry bicycles. The existing vehicle-mounted bicycle racks are generally fixed to the trailer connector of the car through a connecting pipe. When the trunk needs to be opened, the vehicle-mounted bicycle rack needs to be unloaded, especially for models without a trunk such as SUVs or hatchbacks. The trunk lid cannot be opened at all without unloading the vehicle-mounted bicycle rack. Summary of the invention

[0022] 2. In the tiltable bicycle rack of the present invention, when the bicycle is fixed on the supporting frame and the supporting frame is kept in a vertical state, the hook pin is located at the end of the sliding groove away from the opening component and is locked in the hook. At this time, the hook pull rope is in a compressed state, and the hook applies an upward squeezing force to the hook pin, which can prevent the hook pin from moving along the sliding groove toward the opening component. The hook pin can only be separated from the hook when a downward force is applied to the opening component and a retaining force is applied to the supporting frame toward the rear of the car. Any incorrect operation method will not unlock the locking component, which can effectively prevent damage caused by the rotating component flipping due to accidental contact with the opening component.
