[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Example 1, please refer to Figure 1-2 This utility model provides a technical solution: a roof rack connection structure, including connecting frames 2 mounted on the roof rack 1, characterized in that: 2-4 sets of connecting frames 2 are evenly arranged on both sides of the roof rack 1, and the roof rack 1 is installed onto the roof through the connecting frames 2. The specific number of connecting frames 2 can be set according to the length of the car and the roof rack.

[0020] The upper part of the connecting frame 2 is fixedly equipped with a top plate 3 that connects to the luggage rack 1. The side surface of the connecting frame 2 is equipped with an installation block 5. The side surface of the installation block 5 is provided with a groove, and a locking block 6 is installed in the groove. The bottom end of the locking block 6 is provided with a hook 7 for locking the water channel on the side of the car roof. The locking block 6 on the connecting frame 2 can fix the luggage rack 1 to the water channel on the side of the car roof through the hook 7 at its bottom end. The installation is convenient and the fixing is simple. The luggage rack can be easily fixed with a screwdriver or wrench, without the need for professional tools.

[0021] The side surface of the locking block 6 is provided with an elongated countersunk hole 8, and the side surface of the mounting block 5 is provided with a fixing screw hole 9 corresponding to the countersunk hole 8. The adjusting countersunk hole 8 and the fixing screw hole 9 are internally threaded with adjusting bolts 12. The locking block 6 can move up and down in the groove on the mounting block 5. At the same time, the elongated countersunk hole 8 is provided to flexibly adjust the position of the locking block 6, and then flexibly adjust the snapping position of the hook 7 according to the height of the car water channel. It is suitable for the installation needs of different vehicles, greatly improving universality and making it more convenient for consumers to purchase.

[0022] In a preferred embodiment, the upper surface of the roof plate 3 has two elongated holes 4, and the luggage rack 1 has screw holes corresponding to the elongated holes 4. The screw holes are threaded with fixing bolts for fixing the luggage rack 1 and the roof plate 3, which facilitates the replacement of the connecting frame 2. At the same time, the roof plate 3 can flexibly adjust the width of the connecting frame 2 and the luggage rack 1 through the elongated holes 4, and can be finely adjusted according to the width of the car roof, further improving the universality of this structure.

[0023] In the preferred embodiment, both the mounting block 5 and the connecting frame 2 have mounting screw holes 11 on their side surfaces. The mounting screw holes 11 are internally threaded with mounting bolts for fixing the mounting block 5 and the connecting frame 2. The mounting block 5 is connected to the connecting frame 2 by the mounting bolts, which makes disassembly and assembly convenient, operation simple, and modular design facilitates maintenance and replacement of individual components.

[0024] In a preferred embodiment, the lower surface of the locking block 6 has two symmetrically formed bottom fixing holes 10, and the lower surface of the mounting block 5 has two symmetrically formed bottom screw holes corresponding to the bottom fixing holes 10. The bottom screw holes are internally threaded with bottom bolts for fixing the locking block 6 and the mounting block 5. Fixing the locking block 6 and the mounting block 5 from below using the bottom bolts enhances the connection between the locking block 6 and the hook 7, making the luggage rack 1 more secure and reducing driving risks. After fixing the position of the locking block 6 using the adjusting bolt 12, the bottom bolts are then screwed in for further fixation.

[0025] Example 2, please refer to Figure 3 This utility model also provides a technical solution, which is largely the same as Embodiment 1, except that: an adjusting block 13 is sleeved on the outside of the adjusting bolt 12, and a plurality of upper locking teeth 14 are evenly arranged on the lower surface of the adjusting block 13, and a plurality of lower locking teeth 15 matching the upper locking teeth 14 are evenly arranged on the inner upper surface of the adjusting countersunk hole 8. When the position of the locking block 6 is moved, the locking block 6 moves outside the adjusting bolt 12 through the adjusting countersunk hole 8. After it is moved into place, the adjusting block 13 is moved downward so that its upper locking teeth 14 engage and lock with the lower locking teeth 15 inside the adjusting countersunk hole 8. Then the adjusting bolt 12 is rotated, and its nut presses the upper locking teeth 14, which can make the position of the locking block 6 more firmly fixed. During the use of the luggage rack 1 and when the car is in motion, the locking block 6 is not easy to shift and cause the luggage rack 1 to loosen, which further improves the safety of use.

[0026] Example 3, please refer to Figure 4This utility model also provides a technical solution that is largely the same as that in Embodiment 1 or Embodiment 2, except that: a circular retaining plate 16 is fixedly provided at the end of the adjusting bolt 12, and a retaining ring 17 is fixedly provided inside the retaining screw hole 9 on the mounting block 5. The inner diameter of the retaining ring 17 is smaller than the outer diameter of the retaining plate 16. The adjusting bolt 12 can rotate inside the retaining screw hole 9. The retaining plate 16 is blocked by the retaining ring 17, preventing it from coming out of the retaining screw hole 9. This avoids the risk of losing the adjusting bolt 12, retaining block 6, adjusting block 13, etc. during adjustment or disassembly.

[0027] In the preferred embodiment, the clamping plate 16 is an elastic block. When the adjusting bolt 12 is installed for the first time, the clamping plate 16 can be squeezed through the adjusting screw hole 9 and the inner side of the fixing retaining ring 17 into the cavity inside the mounting block 5.

[0028] In a further preferred embodiment, the clamping plate 16 is frustum-shaped, and the diameter of the portion of the clamping plate 16 away from the threaded section of the adjusting bolt 12 is smaller than the inner diameter of the fixing retaining ring 17. The diameter of the portion of the clamping plate 16 connected to the threaded section of the adjusting bolt 12 is larger than the inner diameter of the fixing retaining ring 17. This allows the clamping plate 16 to more easily enter the cavity inside the mounting block 5 through the inner side of the fixing retaining ring 17 when the adjusting bolt 12 is installed for the first time, and it is not easy to detach through the inner side of the fixing retaining ring 17 after entering.

[0029] The parts not disclosed in this utility model are all prior art, and their specific structures, materials, and working principles will not be described in detail. Although embodiments of this utility model have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of this utility model, the scope of which is defined by the appended claims and their equivalents.
