[0024] The anti-sway component 4 includes a connecting hinge 41 arranged on the front and rear sides of the column 2, the connecting hinge 41 is fixedly installed on the column 2, a supporting leg 42 is rotatably arranged inside the connecting hinge 41, and a buffer sleeve 43 is provided on the external sliding sleeve of the end of the supporting leg 42 away from the connecting hinge 41, a fixing rod 44 is arranged inside the buffer sleeve 43, the upper end of the fixing rod 44 is movably arranged inside the supporting leg 42, and a spring 45 is arranged on the external sleeve of the fixing rod 44, the supporting leg 42 and the buffer sleeve 43 are tilted, and a connecting block 46 is arranged on the end of the buffer sleeve 43 away from the supporting leg 42, and the end of the connecting block 46 away from the buffer sleeve 43 is rotatably arranged on the supporting hinge 47, and the bottom side of the supporting hinge 47 is fixedly installed on the top of the fixing plate 48, and the fixing plate 48 is connected to the ground through a screw 49. When the pull rod 3 shakes, the supporting leg 42 slides along the fixing rod 44 in the buffer sleeve 43, and the spring 45 buffers and pulls the supporting leg 42 to reduce the amplitude of shaking and prevent the railing 3 from tipping over.

[0025] A movable groove 421 is provided at one end of the leg 42 close to the buffer sleeve 43, and the upper end of the fixed rod 44 is slidably set inside the movable groove 421. When the railing 3 shakes, the leg 42 slides along the fixed rod 44, so that the leg 42 moves more smoothly and reduces shaking. A limit block 422 is connected to the fixed rod 44 inside the movable groove 421, and the limit block 422 is movably set inside the movable groove 421. The limit block 422 prevents the leg 42 from detaching from the fixed rod 44.

There are multiple groups of latch grooves 71 on the telescopic rod 7, and a latch shaft 72 is slidably installed inside the latch groove 71. The telescopic rod 7 can be flexibly extended and retracted, and the latch shaft 72 is inserted into the latch groove 71 to be fixed, so that the height of the handrail 3 can be adjusted according to actual needs.

[0029] A display board 8 is connected to the top of the telescopic rod 7, and the bottom of the display board 8 is connected to the railing 3. The railing 3 is telescopic and can be adjusted as the telescopic rod 7 rises or falls. A ventilation hole 81 is provided throughout the interior of the display board 8, and the wind goes through the ventilation hole 81 to prevent the wind ambassador from impacting the display board 8 and shaking the railing 3. A reflective warning strip 9 is provided on the front side of the display board 8 to warn pedestrians and vehicles and improve the safety factor.

[0030] Working principle: first, by sliding the movable plate 51, when the movable plate 51 moves to a suitable position, the movable plate 51 is limited and fixed by the bolts 61, so that the pad 52 and the rubber pad 53 are close to the ground, thereby increasing the force-bearing area of ​​the railing 3, preventing the railing 3 from tilting and collapsing easily due to external forces, and effectively preventing external impacts. When the railing 3 shakes, the support leg 42 slides along the fixed rod 44 in the buffer sleeve 43, and the spring 45 buffers and pulls the support leg 42 to reduce the amplitude of the shaking and prevent the railing 3 from tipping over.

[0031] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein.
