Description

Technical Field

[0001] The utility model belongs to the technical field of automobile accessories, and particularly relates to a roof crossbar. Background Art

[0002] The roof crossbar is an accessory installed on the roof of SUVs and off-road vehicles. The roof crossbar spans across the top of the car, making it convenient for car users to fix their luggage on the roof when traveling. Since some cars have less original trunk space, when more people travel, they often encounter embarrassment such as insufficient trunk space; in addition, when people go off-road or travel outdoors, the luggage they carry is sometimes larger, such as bicycles or folding ladders, etc. These tools cannot be placed in the car trunk. After installing a luggage rack, the cargo and luggage can be easily fixed on the roof, making great use of the car's usable space.

[0003] The existing roof cross bars are only fixed by bolts in one direction, so the fixing firmness is poor. In addition, the strength of the rod body is poor and the bearing capacity is poor. Utility Model Content

[0006] Preferably, the connecting member includes a straight pipe and a bent pipe, the straight pipe is sleeved on the outside of the end of the rod body, one end of the bent pipe is fixedly connected to the straight pipe, and the other end is fixedly connected to the fixing plate.

[0007] Preferably, a cavity is provided at the end of the straight tube, a convex strip is provided at the middle portion of the inner wall at the top end of the cavity, and the first threaded hole and the second threaded hole pass through the convex strip.

[0008] Preferably, the rod body is a hollow structure, and an elongated opening is arranged on the upper surface of the rod body along its length direction, and folding plates are arranged on both sides of the elongated opening of the rod body.

[0009] Preferably, a first reinforcing plate is provided at the bottom of the folding plate, two of the first reinforcing plates are connected by a second reinforcing plate, and a third reinforcing plate is provided on the outer side of the first reinforcing plate in the inner cavity of the rod.

[0010] A roof cross bar of the utility model has the following advantages:

[0011] 1. The utility model arranges the convex strip, the first threaded hole and the second threaded hole so that one bolt is fixed upward through the first threaded hole and the other bolt is fixed downward through the second threaded hole, so that the cross bar is fixed more firmly and the structure is reliable.

[0012] 2. The utility model forms a stable I-shaped structure through the cooperation between the two first reinforcement plates and the second reinforcement plate, and cooperates with the third reinforcement plate to greatly improve the overall strength of the rod body, making it safer and more reliable.
