Description

Technical Field

[0001] The utility model relates to the technical field of automobile luggage racks, in particular to an automobile luggage rack expansion bracket. Background Art

[0002] A car luggage rack is a device installed on the roof of a car, mainly used to increase the vehicle's carrying capacity. A car luggage rack usually includes several brackets distributed in parallel on the car roof and cross bars fixed on the brackets. In order to increase the usable space of the car luggage rack, it is necessary to use an expansion bracket in combination.

[0003] Currently, when using an expansion bracket, there is a lack of an expansion direction adjustment mechanism. Usually, the expansion bracket of a luggage rack can only be used by a fixed connection. Since the installation direction and position are fixed, it is difficult to adjust the use space and height of the expansion bracket according to the actual amount of luggage, resulting in relatively limited flexibility in actual use. Therefore, a car luggage rack expansion bracket is proposed to increase the expansion direction adjustment mechanism. By using plug-in, threaded connection, vertical and horizontal different combinations, the flexibility of the expansion bracket can be improved to adapt to different expansion needs, thereby improving the use effect.

[0008] Specifically, the reinforcement assembly includes a support rod, the inner sides of both ends of the support rod are sleeved and connected to the limiting rod, and the inner side of the limiting rod in the support rod is installed with a spring through a spring seat.

[0009] By adopting the above technical solution, an auxiliary reinforcement mechanism can be added, and the safety of the expansion bracket can be improved by plugging in, so that the luggage is less likely to be offset or shaken by the movement of the car.

[0010] Specifically, a bolt is provided on the top of the extension plate, and a nut corresponding to the bolt is provided on the bottom of the extension plate.
