[0026] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model.

[0027] Please see Figures 1-4 This utility model provides an environmentally friendly plastic railing, comprising a railing structure formed by a post 1 and a guardrail 2 for protection. A base plate 11 is installed and connected to the bottom end of the post 1 to enhance the stability of the bottom and improve the stability effect. The post 1 has an upwardly penetrating movable cavity inside to facilitate the removal and movement of a lifting post 12. The lifting post 12 is slidably connected inside the cavity. Several first threaded holes 13 are provided on the corresponding surfaces of the post 1 and the lifting post 12. The first threaded holes 13 are connected by first bolts 14. After the lifting post 12 is moved up and down to adjust different heights, the first bolts 14 can be rotated into the first threaded holes 13 inside the lifting post 12 to fix the lifting post 12 and adjust its height to provide protection at different heights. The lifting post 12 has a sliding groove 19 on both sides that penetrates the upper end. The upper end of the sliding groove 19 facilitates the removal of the sliding block 110, allowing the lifting post 12 to enter the post 1 and slide inside the sliding groove 19. A movable slider 110 is connected, and a connecting rod 18 is installed on the outside of the movable slider 110, passing through the movable slide groove 19. This allows the movable slider 110 to drive the connecting rod 18 to adjust its vertical position within the lifting column 12, thus enabling the installation of the guard rod 2 at different heights. A rotating sleeve 17 is movably connected to the outside of the connecting rod 18 to fix the guard rod 2. A second threaded hole 15 is provided on one side of the movable slider 110 corresponding to the movable slide groove 19, and multiple holes are provided at the through-hole of the movable slide groove 19 to facilitate position adjustment. A second bolt 16 is connected inside the second threaded hole 15, and the connection between the second bolt 16 and the second threaded hole 15 fixes the movable slider 110, thereby fixing the rotating sleeve 17 to the lifting column 12 to fix the guard rod 2, thus improving stability. Connecting rods 18 can also be installed at corresponding positions between columns 1, and the connecting rods 18 are fixedly connected to the outside of the columns 1. A rotating sleeve 17 is also fitted on the outside of the connecting rod 18 to facilitate lower-end protection, thus improving the working effect.

[0028] The guard rod 2 is detachably installed between two columns 1, facilitating disassembly and installation. This allows for quick replacement and repair in case of damage, improving work efficiency and facilitating transportation after disassembly. Both sides of the guard rod 2 are equipped with connecting screws 21 that connect to rotating sleeves 17. The inner side of the rotating sleeve 17 and the outer side of the connecting screws 21 are threaded for engagement, ensuring the rotating sleeve 17 is threaded onto the connecting screws 21. This avoids the instability that occurs when directly fitted onto the connecting screws 21, preventing lateral movement and improving the stability of the guard rod 2.

[0029] Preferably, the inner ring of the rotating sleeve 17 is provided with a protruding ring, and the outer ring of the connecting rod 18 is provided with a stop block 111. This can prevent the rotating sleeve 17 from running out when it moves left and right, thus improving safety performance.

[0030] Working principle: In use, first connect the lower guard rod 2 to the rotating sleeve 17 between the columns 1 to fix the distance between the columns 1. Then, according to the height to be protected, pull the lifting column 12 to stretch it up and down. After reaching the appropriate position, the first bolt 14 is rotated into the first threaded hole 13 to fix the lifting column 12. Then, the rotating sleeve 17 and the connecting rod 18 are moved into the moving slide groove 19 by the moving slider 110. After moving to the appropriate position, the moving slider 110 is fixed by the second bolt 16 and the second threaded hole 15. Then, the guard rod 2 is brought close to both sides of the rotating sleeve 17. Then, the rotating sleeve 17 is rotated to connect with the connecting screw 21 to fix the guard rod 2, thus completing the work.
