Description

Technical Field

[0001] The utility model relates to the technical field of roof cross bars, in particular to an adjustable roof cross bar. Background Art

[0002] Roof bars (often called roof racks or crossbars) are primarily used to increase a vehicle's storage capacity and convenience. They can carry large items like suitcases, bicycles, and skis, making them particularly suitable for long journeys. Furthermore, they provide a mounting point for various accessories (such as racks and clamps) to secure gear. Proper installation and securing methods can effectively prevent items from sliding or falling during driving, thereby ensuring driving safety. Roof bars are primarily made of aluminum alloy, steel, plastic, and composite materials. In daily life, they are practical and enhance the functionality and overall aesthetics of the vehicle.

[0003] In daily use, most existing roof bars are customized or matched according to different vehicle models. This matching method often has specificity and limitations. If the roof bar is damaged, additional configuration is required, which increases the cost of use. Secondly, very few vehicles have a mounting base for the roof bar on the top, but this base is often curved, which is difficult for existing roof bars to adapt to, increasing the installation cost. Therefore, we propose an adjustable roof bar. Utility Model Content

DETAILED DESCRIPTION

[0018] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0019] See also Figures 1 to 4 , an adjustable roof cross bar, comprising a cross bar 1, with two sets of sliding rods 2 symmetrically mounted on the left and right sides of the cross bar 1;

[0020] Before installation, please turn off the vehicle, then place the horizontal bar 1 on the top of the vehicle. Adjust the distance between the horizontal bar 1 and the slide rod 2 according to the width of the horizontal bar on the top of the vehicle. When the distance between the two ends is equal to the distance between the horizontal bars on the top of the vehicle, insert the fixing screws into the first circular through-holes 18 and lock them, fixing the horizontal bar 1 and the slide rod 2 so that they do not slide, facilitating subsequent installation.

[0021] Then, when the fixation is completed, the adjustable component 3 can be adjusted so that the device body is completely fixed to the crossbar on the top of the vehicle;

[0022] In the above, the adjustable component 3 includes a second L-shaped support block 10 fixedly mounted on one end of the slide rod 2, a first L-shaped support block 6 is fixed to the bottom of the second L-shaped support block 10, a second arc-shaped plate 5 is fixed to the bottom of the first L-shaped support block 6, a first slide groove 7 is provided on the inner wall of the first slide groove 7, a slider 11 is slidably provided on the inner wall of the first slide groove 7, a first arc-shaped plate 4 is fixed to the right end of the slider 11, a second arc-shaped through hole 9 is provided on the right side of the inner wall of the first L-shaped support block 6, and two groups of first arc-shaped through holes 8 are symmetrically provided on the right outer wall of the first arc-shaped plate 4. Four groups of fifth through holes 23 are symmetrically formed on the left end of the inner wall of the second L-shaped support block 10. Four groups of first through holes 12 are symmetrically fixed to the top of the second L-shaped support block 10. A third circular through hole 21 is formed on the left end outer wall of the slider 11. A second circular through hole 20 is formed on the left outer top of the first L-shaped support block 6. Two groups of fourth arc-shaped through holes 19 are symmetrically formed on the left outer wall of the first L-shaped support block 6 near the second circular through hole 20. Two groups of fourth through holes 22 are symmetrically formed on the left outer wall of the slider 11 near the third circular through hole 21.

[0023] Specifically, when the distance between the crossbar 1 and the slide bar 2 is fixed, the second curved plate 5 and the first curved plate 4 are cut into the outside of the crossbar on the top of the vehicle, and then the distance between the first curved plate 4 and the crossbar 1 and the second curved plate 5 and the first L-shaped support block 6 is adjusted according to the required height. After adjustment, the corresponding fixing screws are inserted into the third circular through-hole 21 and the fourth arc-shaped through-hole 19. Note that the fixing screws there are all matching fixing screws. When in use, they must be used strictly in accordance with the installation requirements. Then, when the adjustment is completed according to the required height, it should be noted that the crossbar on the top of the vehicle often has a certain curvature. At this time, it should be noted that there is a 10° inclination angle between the first curved plate 4 and the second curved plate 5 that can be adjusted to adapt to different models. Then, because the width of the crossbar on the top of the vehicle is different, the slider 11 is slid to the right until the crossbar on the top of the vehicle can be completely covered. At this time, the matching screws are fixed to the second arc-shaped through-hole 9. After completing the above operations, the fixation of both sides is basically completed.

[0024] In addition, the slide rod 2 and the adjustable component 3 are fixed by screwing a special screw into the inside of the third arc-shaped through hole 13. At the same time, the slide rod 2 and the adjustable component 3 can be freely adjusted according to the horizontal bar on the top of the vehicle, thereby increasing the adaptability of the utility model when in use. Finally, there are four groups of first through holes 12 on the top of the second L-shaped support block 10, which are used to provide support points for the subsequent installation of other equipment.

[0025] Working principle: When in use, first turn off the vehicle, then place the cross bar 1 on the top of the vehicle, and adjust the distance between the cross bar 1 and the slide rod 2 according to the width of the cross bar on the top of the vehicle. When the distance between the two ends is equal to the distance between the cross bars on the top of the vehicle, at this time, insert the fixing screw into the first circular through hole 18 and lock it to fix the cross bar 1 and the slide rod 2 so that there is no sliding between the cross bar 1 and the slide rod 2. After the distance between the cross bar 1 and the slide rod 2 is fixed, at this time, cut the second curved plate 5 and the first curved plate 4 into the outside of the cross bar on the top of the vehicle, and then adjust the distance between the first curved plate 4 and the cross bar 1 and the second curved plate 5 and the first L-shaped support block 6 according to the required height. After adjustment, insert the corresponding fixing screws into the first circular through hole 18 to fix the cross bar 1 and the slide rod 2. In the three circular through holes 21 and the fourth arc-shaped through hole 19, please note that the fixing screws here are all matching fixing screws. When in use, they must be used strictly in accordance with the installation requirements. Then, after the adjustment is completed according to the required height, it should be noted that the cross bar on the top of the vehicle often has a certain curvature. At this time, it should be noted that there is a 10° inclination angle between the first arc-shaped plate 4 and the second arc-shaped plate 5 that can be adjusted to adapt to different vehicle models. Then, because the width of the cross bar on the top of the vehicle is different, slide the slider 11 to the right until the cross bar on the top of the vehicle can be completely covered. At this time, fix the matching screws to the second arc-shaped through hole 9. After completing the above operations, the fixation on both sides is basically completed.

[0026] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
