The second support rod 605 is sleeved around the inner connecting rod 604.

[0034] The luggage rack 40 has a side guard 70 on top, and a through groove 80 is provided on the side guard 70. A rope winding end 90 is provided in the middle of the through groove 80.

[0035] This utility model of a lightweight, high-strength, multi-purpose luggage rack enables quick assembly and disassembly of the luggage rack 40 and support frame 10 through the snap-fit ​​connection between the slot 20 and the mounting block 30. The four connecting ends 303 further enhance the overall stability of the luggage rack 40 after installation, effectively preventing the luggage rack from shaking due to bumps during travel. The support component 60 slides within the slide groove 50 via the slider 602, allowing for flexible adjustment of the support position according to the size and quantity of luggage. The sleeve design between the inner connecting rod 604 and the second support rod 605 enables the support component 60 to extend and retract, facilitating its disassembly. The support components 60 are all made of high-strength aluminum alloy, ensuring structural strength while reducing structural weight. The side protective frame 70 provides lateral protection for items placed on the luggage rack, preventing items from slipping off the sides. The rope winding end 90 within the through groove 80 facilitates rope winding, making it easy to tie and secure luggage to the luggage rack. This multi-layered fixing structure ensures the safety of items during transportation.

[0036] Furthermore, in another embodiment, the slot 20 further includes a limiting fixing post 201, which is disposed in the slot 20. The mounting block 30 also includes a fixing hole 302, which is opened inside the slot 301. The inner diameter of the fixing hole 302 is larger than the outer diameter of the limiting fixing post 201. The fixing hole 302 and the limiting fixing post 201 cooperate with each other to limit the mounting block 30. A bolt receiving block is provided at the upper end of the fixing hole 302.

[0037] The limiting and fixing post 201 passes through the fixing hole 302, and the bolt receiving block contacts the top of the limiting and fixing post 201. At this time, the bolt is screwed into the bolt receiving block and connected to the limiting and fixing post 201 to complete the fixing of the mounting block 30. The limiting and fixing post 201 and the fixing hole 302 can cooperate with each other to limit the mounting block 30, which facilitates the installation of the mounting block 30 by relevant personnel, and at the same time ensures the stability of the mounting block 30 during use and prevents the mounting block 30 from sliding during use.

[0038] Furthermore, in another embodiment, the support assembly 60 further includes a fixing groove 603, a cavity 606, and a limiting spring 607. The fixing groove 603 is formed in the slider 602, the cavity 606 is formed at one end of the second support rod 605 near the first support rod 601, and the limiting spring 607 is engaged between the cavity 606 and the inner connecting rod 604.

[0039] The limiting spring 607 is locked in the cavity 606. When needed, the relevant personnel can push the inner connecting rod 604 toward the limiting spring 607. During this process, the total length of the support assembly 60 will be shortened, which makes it easier for the relevant personnel to remove the support assembly 60 from the slide groove 50.

[0040] Furthermore, in another embodiment, a limiting plate 6011 is provided at the bottom of the first support rod 601 near the end of the second support rod 605, a limiting collar 6051 is provided at the bottom of the second support rod 605 near the end of the first support rod 601, and a baffle 6012 is detachably provided at the end of the limiting plate 6011 near the end of the second support rod 605.

[0041] When the support assembly 60 extends to its maximum length, the limiting collar 6051 contacts the baffle 6012, preventing the inner connecting rod 604 from completely disengaging from the second support rod 605. The baffle 6012 is detachably connected to the limiting plate 6011. When it is necessary to remove the inner connecting rod 604 from the second support rod 605, simply remove the baffle 6012 to release the limitation of the limiting plate 6011 on the limiting collar 6051, thereby facilitating the replacement of the limiting spring 607 by relevant personnel.

[0042] Furthermore, in another embodiment, the inner wall of the through groove 80 is provided with a threaded post 801, the threaded post 801 is provided with a pressing threaded rod 802, and the rope winding end 90 is provided with an arc-shaped groove 901.

[0043] The extrusion threaded rod 802 is threadedly connected to the threaded post 801. Rotating the extrusion threaded rod 802 allows it to move back and forth within the threaded post 801. When the rope is wound around the rope winding end 90, rotating the extrusion threaded rod 802 causes one end to contact and compress the rope, effectively preventing the rope from loosening on the rope winding end 90. The curvature of the arc groove 901 increases the contact area between the rope and the rope winding end 90, further improving the stability of the rope after winding and reducing the risk of damage to the rope due to friction.

[0044] Working principle: Relevant personnel can pass the limiting fixing post 201 through the fixing hole 302, and the bolt receiving block contacts the top of the limiting fixing post 201. At this time, the bolt is screwed into the bolt receiving block and connected to the limiting fixing post 201, and then the mounting block 30 can be installed in the slot 20. During this process, the limiting fixing post 201 and the fixing hole 302 can cooperate with each other to limit the mounting block 30.

[0045] After the installation of the mounting block 30 is completed, the relevant personnel can install the support component 60 in the slide groove 50 through the slider 602. The support component 60 can slide in the slide groove 50 through the slider 602. After the support component 60 is installed, the relevant personnel can adjust the position of the support component 60 according to actual needs, which makes it convenient for the relevant personnel to flexibly adjust the support position of the support component 60 according to the actual size and quantity of luggage.

[0046] After the support component 60 is adjusted, the relevant personnel can place the luggage in the luggage rack 40, then use ropes to secure the luggage and wrap the ropes around the rope winding end 90. Then, the compression threaded rod 802 can be rotated and squeezed. The compression threaded rod 802 is threadedly connected to the threaded post 801. Rotating the compression threaded rod 802 allows it to move back and forth within the threaded post 801. After the rope is wrapped around the rope winding end 90, rotating the compression threaded rod 802 so that one end contacts and squeezes the rope can effectively prevent the rope from loosening on the rope winding end 90. The curvature of the arc groove 901 can increase the contact area between the rope and the rope winding end 90, further improving the stability of the rope after winding and reducing the risk of the rope being damaged due to friction.
