[0030] When the operator rotates the screw 7, the first movable block 8 will move downward in the vertical opening 6, at this time, the two inclined rods 12 at the bottom of the first movable block 8 will push the two supporting frames 10 to rotate, and at this time, the outer surface of the roller 11 will roll on the ground, thereby effectively improving the stability of the protective fence placing support.

[0031] Wherein, the both sides of the guardrail frame 1 are fixedly installed with side blocks 13, and the outer side of the side block 13 is provided with a side opening 14.

[0032] Due to the design of the two side blocks 13, the stability of the guardrail frame 1 as a whole can be effectively improved.

[0033] Wherein, the inner wall of the side block 13 is provided with a tooth opening 15 inside the side opening 14, and the inside of the top end of the side block 13 movably sleeved with a movable plate 16.

[0034] And the outer surface of the movable plate 16 and the inside of the top end of the side block 13 are smooth, so that the movable plate 16 is more stable during subsequent lifting movement.

[0035] Wherein, the top of the movable plate 16 is fixedly installed with a warning light 17, and the top of the warning light 17 is fixedly installed with a top cover 18, which is located in the inside of the top end of the side block 13 and movably connected with the inner wall of the side block 13.

[0036] Due to the design of the top cover 18, the top of the movable plate 16 is well protected, and the damage of the warning light 17 caused by external rainwater is avoided.

[0037] Wherein, the bottom of the movable plate 16 is fixedly installed with a vertical rod 19, the bottom end of the vertical rod 19 penetrates through the side block 13 and extends into the inside of the side opening 14 and is fixedly installed with a second movable block 20, and the outer surface of the second movable block 20 is movably connected with the inner wall of the side opening 14.

[0038] Due to the limiting effect of the side block 13 on the second movable block 20, the second movable block 20 is more stable during subsequent lifting movement.

[0039] Wherein, the inside of the second movable block 20 movably sleeved with a moving block 22, the left side of the moving block 22 is fixedly installed with a fixed rod 21, the other end of the fixed rod 21 penetrates through the second movable block 20 and extends into the inside of the left side of the second movable block 20, and the left end of the fixed rod 21 is fixedly installed with a handle 24 outside the side block 13.

[0040] The operator can pull the handle 24, so that the fixed rod 21 drives the moving block 22 to move in the inside of the second movable block 20.

[0041] The outer surface of the fixed rod 21 is movably sleeved with the flexible spring 25 between the left side of the moving block 22 and the inner wall of the second moving block 20, one end of the flexible spring 25 is fixedly connected with the left side of the moving block 22, and the other end of the flexible spring 25 is fixedly connected with the inner wall of the second moving block 20.

[0042] Due to the design of the flexible spring 25, the moving block 22 has a good reset effect after movement.

[0043] The right side of the moving block 22 is fixedly connected with the clamping tooth 23, and the right side of the clamping tooth 23 is movably connected with the inside of the toothed port 15.

[0044] Due to the meshing effect between the clamping tooth 23 and the toothed port 15, the position of the second moving block 20 is well fixed, and accidental downward sliding and falling of the second moving block 20 is avoided.

[0045] The outer surface of the lead screw 7 is fixedly sleeved with the limiting shaft 30 located inside the top end of the guardrail frame 1, and the outer surface of the limiting shaft 30 is movably sleeved with the inside of the top end of the guardrail frame 1.

[0046] Due to the design of the limiting shaft 30, the lead screw 7 is well limited, and is more stable during rotation.

[0047] The top of the guardrail frame 1 is fixedly provided with the fixed frame 26 located on both sides of the lead screw 7, the inside of the fixed frame 26 is movably sleeved with the movable shaft 27, the outer surface of the movable shaft 27 is fixedly sleeved with the movable wheel 28 located inside the fixed frame 26, and the outer surface of the movable wheel 28 is fixedly provided with the protruding block 29.

[0048] When external personnel recklessly cross the construction protective guardrail, at this time, the movable shaft 27 can drive the movable wheel 28 and the protruding block 29 to rotate, so that the hands of the external personnel cannot find a suitable supporting force point, and at this time, the external personnel will not climb and cross from the perspective of their own safety.

[0049] Working principle and use process:

[0050] When the external wind force is too large, at this time, the operator can rotate the lead screw 7, so that the first moving block 8 moves downward in the vertical port 6, at this time, the two inclined rods 12 will push the two supporting frames 10 to rotate outward around the circular shaft 9, and at the same time, the two rollers 11 will roll on the ground, finally, the two supporting frames 10 can well support the whole guardrail frame 1, so that the whole guardrail frame 1 will not be tilted due to the large external wind force.

[0051] When it is dark, the operator can pull the handle 24 outwards at this time, so that the fixed rod 21 drives the moving block 22 to move in the interior of the second movable block 20, and at this time the flexible spring 25 will be pressed by the moving block 22, and finally the clamping tooth 23 will be separated from the interior of the tooth port 15, at this time the operator can pull the handle 24 upwards, so that the second movable block 20 drives the vertical rod 19, the movable plate 16, the warning light 17 and the top cover 18 to move upwards, at this time the warning light 17 will be exposed at the top of the side block 13, and then the operator can release the handle 24, and due to the elastic recovery effect of the flexible spring 25, the moving block 22 will drive the clamping tooth 23 to be clamped in the tooth port 15 at the corresponding position, thereby a good fixing effect on the position of the second movable block 20 can be achieved, at this time due to the operation of the warning light 17, warning light will be emitted, thereby a good warning effect on the passing pedestrians can be achieved.

[0052] When the passing pedestrians try to cross the protective guardrail, at this time the pedestrians generally put their hands on the outer surface of the movable wheel 28, at this time due to the contact between the convex block 29 and the hands of the pedestrians, the hands of the pedestrians are uncomfortable, thereby a preliminary discouraging effect is achieved, and due to the rotation of the movable wheel 28 and the movable shaft 27, the hands of the pedestrians cannot find a suitable supporting force point, thereby the crossing of the pedestrians is prevented, and the personal safety of the pedestrians is ensured.
