[0002] Logistics transportation refers to the process of transporting items from one location to another, which usually involves the use of various equipment and systems, including conveyor belts, roller conveyors, conveyor pipes, containers, trucks, ships, etc. In large warehouses and logistics sorting centers, roller conveyors are often used to transport goods, parcels and cargo containers to transport them from one processing area to another.

[0003] In the prior art, some conveying rollers are composed of three parts: a cylinder, a shaft, and an end assembly. After carrying the goods, the goods are conveyed by rotation. When the size of the goods is large, in order to facilitate the conveying, the size of the matching roller must be longer. The longer the roller, the greater the disturbance of the internal shaft with the increase of its own weight, and eventually the shaft hangs down and causes the shaft to get stuck. Therefore, in view of the above shortcomings, a stable long-distance roller is proposed. Utility Model Content

The right side of the pressing rod 12 is fixedly connected to a connecting frame 13, and the pressing rod 12 moves with the connecting frame 13. The left and right sides of the cylinder 2 are fixedly connected to hollow columns 14, and a groove 15 is provided inside the hollow column 14, which realizes the sealing of the roller shaft 1, thereby preventing the material from leaking from the side or bottom of the roller, reducing energy waste.

[0023] Reference Figures 1 to 3 The telescopic assembly includes a slide bar 9, and a spring 10 is fixedly connected to the left side of the slide bar 9. The slide bar 9 drives the compression of the spring 10. The left side of the spring 10 is fixedly connected to the left inner wall of the cover body 6, which improves the stability of the spring 10.
