[0024] Reference Figures 1-8 As shown in the figure, a lifting guardrail includes a fixed guardrail 1 and a movable guardrail 2 arranged in the fixed guardrail 1. The fixed guardrail 1 is composed of two groups of first side columns 101 and first guard plates 102 between the first side columns 101. The movable guardrail 2 is composed of two groups of second side columns 201 and second guard plates 202 between the second side columns 201. The first side column 101 is provided with a movable slot 3 for the second guard plate 202 to move therein in a through manner. The movable slot 3 is provided with a movable cover 4 at the lower part.
[0025] A self-locking gas spring is arranged in the first side column 101. In the initial state, the movable guardrail 2 completely overlaps the fixed guardrail 1. At this time, the gas spring is in a self-locking state. The gas spring is unlocked by pressing the fixed guardrail 1. The second side column 201 can be moved upward in the first side column 101 by the gas spring.
[0026] In order to ensure that the cover 4 can move in the movable slot 3 while ensuring that the cover 4 cannot be separated from the movable slot 3, the cover 4 is provided with a positioning block 9 and a T-shaped slot 12. Figure 4As shown, the convex plates are arranged between the movable grooves 3 at both sides of the movable grooves 3, thereby forming steps 301 on the movable grooves 3, the cover 4 comprises cover plates 401 which are fitted with the steps 301 and clamping hooks 402 which are arranged vertically on both sides of the cover plates 401, two groups of the clamping hooks 402 are arranged between two groups of the convex plates, and hook-shaped end heads are arranged at the ends of the clamping hooks 402, so that the cover 4 can be limited in the transverse direction, and the surface of the cover plates 401 is flush with the surface of the first side column 101.
[0027] In order to fix the first side column 101 on the ground, a bottom plate 5 is arranged below the first side column 101, and the first side column 101 and the bottom plate 5 are fixed by fixing screws which are screwed from bottom to top, so that the bottom of the first side column 101 is closed, in order to prevent water from accumulating in the first side column 101, such as Figure 3 As shown, a water guide 4011 is arranged below the cover plate 401, and the water guide 4011 is in an inverted U shape.
[0028] Since the second side column 201 is arranged in the first side column 101, it is necessary to prevent the second side column 201 from easily shaking in the first side column 101, at least two anti-shaking blocks are arranged in the cavity of the second side column 201, including a first anti-shaking block 6 arranged at the top of the first side column 101 and a second anti-shaking block 7 arranged at the bottom of the second side column 201, the first anti-shaking block 6 is fixed, and the second anti-shaking block 7 moves synchronously with the second side column 201, in order to fix the first anti-shaking block 6, a top cover is arranged at the top of the first side column 101, a fastening screw is arranged on the top cover and screwed into the first anti-shaking block 6 and the first side column 101 at the same time, thereby fastening the first anti-shaking block 6, a plurality of reinforcing ribs are arranged on the inner wall of the first anti-shaking block, and the reinforcing ribs are in contact with the peripheral wall of the second side column, similarly, a fastening screw is arranged at the bottom of the second anti-shaking block 7 and screwed into the bottom of the second side column 201 from one side of the second anti-shaking block 7, thereby fastening the second anti-shaking block 7, and in order to reduce the material cost, a plurality of reinforcing ribs which are fitted with the inner wall of the first side column 101 can be arranged around the second anti-shaking block 7.

Since the movable guardrail 2 is pulled up or pressed down many times in the use scenario, a blocking strip can be arranged at the upper cover of the second guard plate 202 to block the second guard plate 202 from being separated from the guard groove 8, so that the second guard plate 202 can be prevented from moving when being pulled up. Meanwhile, a positioning block 9 is arranged in the guard groove 8 below the second side column 201, the upper end of the second guard plate 202 is flush with the second side column 201, and the height of the second guard plate 202 is lower than that of the second side column 201. The positioning block 9 is fixed in the guard groove 8 of the second side column 201 by a fastening screw, so that the second guard plate 202 is prevented from moving when being pressed down.
[0030] Further, a wind blocking assembly is arranged at the lower end of the first guard plate 102, which is composed of a U-shaped sleeve 10 and a sealing strip 11 arranged on the U-shaped sleeve 10. The U-shaped sleeve 10 is clamped at the lower end of the second guard plate 202, and the sealing strip 11 achieves a wind blocking effect. Specifically, a T-shaped groove 12 is arranged at the lower side of the U-shaped sleeve 10, and a T-shaped end 13 that cooperates with the T-shaped groove 12 is arranged on the sealing strip 11. When being installed, the sealing strip 11 is inserted into the T-shaped groove 12 on the U-shaped sleeve 10 from the side. The sealing strip 11 can be a rubber strip or a brush.
