[0020] Embodiment 1: Figure 1-3As shown, the utility model provides a movable central guardrail, including two bottom plates 1, both sides of the upper end of the bottom plates 1 are fixed with upright poles 2, two cross bars 21 are fixedly arranged between the two upright poles 2, a plurality of universal wheels 4 are fixedly arranged at the lower end of the bottom plates 1, four universal wheels 4 are arranged at the lower end of one of the bottom plates 1, and the four universal wheels 4 are distributed in a rectangular array, a through-type slide groove 11 is provided at the upper end of the bottom plate 1, a vertical plate 12 is slidably provided on the inner wall of the slide groove 11, a placing plate 19 is fixedly arranged at the lower end of the vertical plate 12, a lifting plate 15 is fixedly arranged at one end of the vertical plate 12, a screw rod 13 is rotatably provided at the upper end of the bottom plate 1, a turntable 14 is fixedly arranged at the upper end of the screw rod 13, the screw rod 13 and the lifting plate 15 are threadedly sleeved together, four positioning blocks 16 distributed in a rectangular array are fixedly arranged at the upper end of the bottom plate 1, and the positioning blocks 16 corresponding to two positions and the vertical plate 12 are movably inserted with positioning columns 17, and a plurality of positioning columns 17 are provided at one end of the vertical plate 12 for use with the positioning columns 17 The fixing groove 18 is provided with two fixing grooves 18 on one side of the vertical plate 12, and the four fixing grooves 18 on the vertical plate 12 are distributed in a rectangular array. The vertical rod 2 and the cross bar 21 constitute a guardrail structure. An adjustment structure is placed on the bottom plate 1. When the guardrail is placed and installed, the height of the placement plate 19 is lower than the universal wheel 4. When the guardrail needs to be moved, the height of the placement plate 19 is adjusted to be higher than the universal wheel 4. The specific operation method is to rotate the turntable 14, and the lifting plate 15 is lifted and lowered under the rotation of the screw rod 13. The lifting plate 15 drives the vertical plate 12 to lift and lower in the slide groove 11. After adjusting to a suitable height, it is positioned and fixed by the positioning column 17 at the upper end of the positioning block 16. The fixing grooves 18 of different heights enable the vertical plate 12 to be fixed at different heights, thereby increasing the stability when moving or fixing. The adjustment is simple and the stability after adjustment is high. When the vehicle is congested, the fixed guardrail can be moved, providing a solution to the one-way congestion of the road and facilitating the unblocking of traffic.

[0021] Five reinforcing rods 22 are fixed between the two upper and lower horizontal rods 21, and a reinforcing column 23 is fixed between two adjacent reinforcing rods 22.

An anti-slip pad 110 is fixed on the lower end of the placement plate 19. The guardrail structure can be fixed on the ground through the fixing block 111, and the friction force contacting the ground is increased by the anti-slip pad 110, so that the guardrail is placed more stably.

[0023] Embodiment 2: Figure 4As shown, two connecting rods 31 are fixedly provided at the outer end of the vertical rod 2, and the upper ends of the four corresponding connecting rods 31 are movably inserted with connecting bolts 3, and the four connecting rods 31 located on the outer surface of the connecting bolt 3 are alternately distributed at equal intervals up and down, and a through-type through groove 32 is opened on one side of the upper end of the connecting rod 31, and a placement rod 33 is fixedly provided on the lower side of the outer end of the vertical rod 2 located on the upper end side of the base plate 1, and a placement groove 34 is opened on the upper end of the placement rod 33 for cooperating with the connecting bolt 3, and the guardrail structure is connected through the connecting rod 31 and the connecting bolt 3, specifically, the connecting bolt 3 is inserted into the through groove 32 in the connecting rod 31 on both sides of the guardrail structure to be connected, and the lower end of the connecting bolt 3 is inserted into the placement groove 34 on the corresponding placement rod 33. This connection method allows the two adjacent guardrail structures to be rotated a certain angle, which has a wider use prospect than the guardrail whose connection point cannot be rotated, and can cooperate with the movement of the guardrail structure, and has higher versatility.

[0024] Working principle: the vertical pole 2 and the horizontal pole 21 constitute the guardrail structure, and the adjustment structure is placed on the bottom plate 1. When the guardrail is placed and installed, the height of the placement plate 19 is lower than the universal wheel 4. When the guardrail needs to be moved, the height of the placement plate 19 is adjusted to be higher than the universal wheel 4. The specific operation method is to rotate the turntable 14, and the lifting plate 15 is lifted and lowered under the rotation of the screw rod 13. The lifting plate 15 drives the vertical plate 12 to lift and lower in the slide groove 11. After adjusting to a suitable height, it is positioned and fixed by the positioning column 17 at the upper end of the positioning block 16. The fixing grooves 18 of different heights allow the vertical plate 12 to be fixed at different heights, thereby increasing the stability when moving or fixing. The adjustment is simple and the stability after adjustment is high. When the vehicle is congested, the fixed guardrail can be moved, providing a solution to the one-way congestion of the road and facilitating the unblocking of traffic.

[0025] The reinforcing rod 22 and the reinforcing column 23 make the guardrail have a higher structural strength and a better protective effect;

[0026] The guardrail structure can be fixed on the ground by the fixing block 111, and the friction force of contacting the ground is increased by the anti-slip pad 110, so that the guardrail is placed more stably;

[0027] The guardrail structure is connected through a connecting rod 31 and a connecting bolt 3. Specifically, the connecting bolt 3 is inserted into the through groove 32 in the connecting rod 31 on both sides of the guardrail structure to be connected, and the lower end of the connecting bolt 3 is inserted into the placement groove 34 on the corresponding placement rod 33. This connection method allows two adjacent guardrail structures to be rotated at a certain angle. Compared with guardrails that cannot rotate at the connection point, it has a wider range of use prospects, can cooperate with the movement of the guardrail structure, and is more versatile.
