Description

Technical Field

[0001] The utility model relates to a roof luggage rack. Background Art

[0002] With the popularity of automobiles, more and more users choose to install luggage racks on the roof to expand the vehicle's cargo space and facilitate the carrying of large luggage or sports equipment. The roof luggage racks commonly used in the market are usually composed of a fixed frame, support legs, transverse tubes and other components, and are installed on the top of the vehicle to form an additional load-bearing platform. However, these roof luggage racks in the prior art have certain limitations, especially when the vehicle is equipped with a sunroof.

[0003] The vertical rods and transverse tubes of traditional roof racks are usually fixed structures and cannot be adjusted as needed. When the vehicle's sunroof conflicts with the transverse tube position of the roof rack, the vertical rods often block the opening of the sunroof, making it impossible for users to leave the vehicle through the sunroof or enjoy the convenience of opening the window for ventilation. Utility Model Content

[0004] The utility model aims to provide a roof luggage rack which can freely adjust the position of a vertical rod, avoid blocking the skylight and has a flexible use mode.

[0005] The purpose of the utility model is achieved in this way:

[0006] A roof luggage rack comprises a frame, a support leg for connecting to the top of a car, a vertical rod and a locking device, wherein the support leg is arranged on the frame, the support leg supports the frame upward, and the upper and lower sides of the inner cavity of the frame are both provided with transverse tubes;

[0007] The vertical rod is slidably seated in the inner cavity of the frame, the upper end of the vertical rod abuts against the transverse tube on the upper side of the inner cavity of the frame, and the lower end of the vertical rod abuts against the transverse tube on the lower side of the inner cavity of the frame;

[0008] When the vertical rod slides to a suitable position, the vertical rod and the transverse tube are locked by a locking device.

[0009] By arranging a slidable vertical rod on the inner cavity of the frame, the user can adjust the position of the vertical rod as needed. This design effectively avoids the problem that the fixed vertical rod of the traditional roof rack may block the sunroof, and is particularly suitable for vehicles equipped with sunroofs, so that the sunroof can be opened and used normally without being blocked.

[0010] Since the vertical rod can slide to the appropriate position and be fixed by the locking device, the installation and removal process of the vertical rod is more convenient. Without the need to make complicated adjustments to the frame structure, users can easily adjust the position of the vertical rod and ensure its stability, which improves the convenience of use and the ease of operation.

[0011] The upper and lower ends of the vertical rod are respectively against the transverse tubes on the upper and lower sides of the inner cavity of the frame and are fixed by a locking device to ensure the stability of the vertical rod. No matter in which position, the roof rack can be ensured to have sufficient strength and stability, thereby improving safety during driving.

[0012] This design is suitable for different types of vehicles, especially those with sunroofs. Through the flexible adjustment of the vertical rod position, the luggage rack can not only meet the use requirements of conventional vehicles, but also avoid affecting the function of the sunroof, increasing the applicability of the roof luggage rack.

[0013] By reasonably adjusting the position of the vertical rod, users can flexibly adjust the vertical rod layout of the luggage rack according to actual loading needs, optimize the use space of the roof luggage rack, and further improve the vehicle's carrying capacity and functionality.

[0014] The purpose of the utility model can also be solved by the following technical measures:

[0015] Furthermore, the transverse tube is provided with transverse slots along its length direction, and the upper and lower ends of the vertical rods are provided with through holes corresponding to the positions of the transverse slots;

[0016] The locking device comprises a bolt and a nut, the head diameter of the bolt is larger than the diameter of the transverse notch, and the tail diameter of the bolt is smaller than the diameter of the through hole;

[0017] The tail of the bolt passes through the horizontal notch of the corresponding horizontal tube and the through hole of the corresponding vertical rod and extends outward to connect the nut, so that the vertical rod and the horizontal tube are locked together.

[0018] By opening transverse notches on the transverse tube and opening through holes at the upper and lower ends of the vertical rod, the bolts in the locking device can be accurately positioned and passed through these notches and through holes to ensure that the vertical rod and the transverse tube are tightly connected. The design of the bolt head diameter being larger than the transverse notch prevents the bolt from falling off, further enhancing the locking stability and safety of the luggage rack.

[0019] The design of the locking device adopts a simple combination of bolts and nuts, which is easy to use. Users can quickly lock or loosen the vertical rod and the horizontal tube by simply rotating the nut. This simple structure not only reduces the manufacturing cost, but also allows users to easily adjust and install without complex tools or professional knowledge.

[0020] After the tail of the bolt passes through the through hole of the vertical rod and is fixed with the nut, the vertical rod will not slide or move in the locked state, which effectively prevents the vertical rod from loosening or shifting due to vibration or bumps during vehicle driving, ensuring the stability and safety of the roof rack.

[0021] Since the bolt head diameter is larger than the transverse slot and the nut is firmly fixed in the through hole of the vertical rod, the entire locking device can provide high mechanical strength and can withstand large loads. In this way, the roof rack can still maintain sufficient strength and stability when carrying heavy objects, and is not prone to loosening or deformation.

[0022] The structure of bolt and nut connection allows the user to adjust the position of the vertical rod according to actual needs, and firmly fix it in different positions through the locking device. In this way, the luggage rack can adapt to items of different sizes and shapes, making it more flexible and practical.

[0023] The bolts and nuts of the locking device are usually made of corrosion-resistant, high-strength materials, such as stainless steel or alloy steel, which can remain firm and durable for a long time, adapt to various complex weather and environmental conditions, and extend the service life of the roof rack.

[0024] The beneficial effects of the utility model are as follows:

[0025] The utility model provides a slidable vertical rod on the inner cavity of the frame, and the user can adjust the position of the vertical rod as needed. This design effectively avoids the problem that the fixed vertical rod of the traditional roof luggage rack may block the sunroof, and is particularly suitable for vehicles equipped with sunroofs, so that the sunroof can be opened and used normally without being blocked.

[0026] The utility model can adjust the vertical rod positions reasonably, so that the user can flexibly adjust the vertical rod arrangement of the luggage rack according to actual loading requirements, thereby optimizing the use space of the roof luggage rack and further improving the carrying capacity and functionality of the vehicle.

[0027] The utility model provides a transverse notch on the transverse tube and through holes on the upper and lower ends of the vertical rod, so that the bolts in the locking device can be accurately positioned and pass through the notches and through holes, ensuring that the vertical rod is tightly connected to the transverse tube. The design that the bolt head diameter is larger than the transverse notch prevents the bolt from falling off, further enhancing the locking stability and safety of the luggage rack.
