Description

Technical Field

[0001] This utility model relates to the field of luggage rack technology, specifically to an aluminum alloy luggage rack for automobile roofs. Background Technology

[0002] A car roof rack is a cargo rack installed on the roof or outside the trunk of a vehicle. It is mainly used to expand the vehicle's storage space and is suitable for long-distance travel, outdoor activities, or daily cargo needs. For example, a car roof rack disclosed in Chinese patent literature (application number: CN202320611396.8) has a storage rack for placing luggage. However, the storage rack does not have any limiting mechanism. During vehicle movement, the luggage is easily displaced due to its own inertia caused by bumps or the vehicle starting and stopping. At the same time, the protective rope and safety buckle are set separately. During the process of securing the luggage, the luggage is bumped, causing the protective rope to move, and the protective rope cannot properly secure the luggage.

[0003] Therefore, we propose an aluminum alloy roof rack for automobiles. Utility Model Content

The pull plate moves the fixing block to the right via the positioning rod, disengaging the fixing block from the positioning groove and releasing the fixing of the mounting shaft. The load-bearing rod rotates via the mounting shaft. After rotating 90 degrees, the load-bearing rod is in a vertical position. The pull plate is released, and the spring pushes the limit plate to move the positioning rod. The positioning rod pushes the fixing block to lock the mounting shaft in the positioning groove, thus fixing the load-bearing rod. At this time, the adjusted load-bearing rod is higher than the unadjusted load-bearing rod. Adjust the load-bearing rods at both ends of the luggage to position the luggage between the two sets of adjusted load-bearing rods. After the luggage is placed on the luggage rack, the luggage will not shift due to bumps and the inertia of the car starting and stopping when the vehicle moves, thus making the luggage rack more stable during the transportation of luggage in the vehicle.

[0013] 2. The first and second elastic bands pull the U-shaped positioning block, and the right end of the U-shaped positioning block locks into the fixing port, fixing the U-shaped positioning block to the positioning block. The first and second elastic bands secure the luggage. The first elastic band is fixed by the U-shaped positioning block. The first and second elastic bands are fixedly connected to each other. Through cross or mesh connection, the elastic bands can completely prevent the elastic bands from slipping due to vibration or wind during the journey, reducing the risk of luggage displacement. It is especially suitable for long-distance or bumpy road conditions.
