A fixing block 14 is fixedly connected to the top outer wall of the extension rod 8. A first bevel gear 10 is installed at the bottom of the screw 7. The rotating rod 11 is rotatably connected to the first column 1. The rotating rod 11 is provided with a second bevel gear 12. The first bevel gear 10 and the second bevel gear 12 are connected. The first column 1 and the second column 2 are meshedly connected, and the structure is completely consistent with that of the first protective plate 4, which is composed of a first horizontal plate, a second horizontal plate and a third horizontal plate; the second protective plate 5 is composed of a fourth horizontal plate, a fifth horizontal plate and a sixth horizontal plate; the first horizontal plate and the fourth horizontal plate are fixedly connected to the fixing blocks 14 arranged on the first column 1 and the second column 2, respectively; the third horizontal plate and the sixth horizontal plate are fixedly connected to the outer walls of the first column 1 and the second column 2, respectively; guide grooves 17 are provided on the first column 1 and the second column 2; guide strips 23 are provided on the outer walls of the second and fifth horizontal plates; the guide strips 23 are engaged with the guide grooves 17; mounting grooves 18 are provided on the second, third, fifth and sixth horizontal plates; telescopic rods 19 are installed in the mounting grooves 18; and the other ends of the telescopic rods 19 are fixedly connected to the bottom outer wall of the upper horizontal plate.

[0025] The utility model provides an adjustable construction guardrail, a slide groove 15 is opened on the inner wall of the placement groove, and a slider 16 is fixedly connected to the outer wall of the extension rod 8. The extension rod 8 is slidably connected to the slide groove 15 through the slider 16, which can limit the extension rod 8 to prevent the extension rod 8 from rotating with the rotation of the screw rod 7, and can also prevent the extension rod 8 from being separated from the screw rod 7, affecting the use effect.

[0026] The utility model provides an adjustable construction guardrail, a rotating rod 11 is fixedly connected with a rotating disk 13, the rotating disk 13 and the rotating rod 11 are integrated into one structure, the rotating rod 11 can be easily driven to rotate by the rotating disk 13, which is conducive to improving the convenience of operation.

[0027] The utility model discloses an adjustable construction guardrail, wherein the first horizontal plate, the second horizontal plate and the third horizontal plate are all provided with limit grooves 22, the fourth horizontal plate, the fifth horizontal plate and the sixth horizontal plate are all fixedly connected with limit blocks 24, and the limit blocks 24 are engaged with the limit grooves 22, so that the first guard plate 4 and the second guard plate 5 can always maintain a connection relationship, and prevent the two from being disconnected and affecting the use.

[0028] The utility model discloses an adjustable construction guardrail, wherein the first and third transverse plates are provided with limit holes 21, the limit holes 21 are screw holes, the fourth and sixth transverse plates are provided with limit bolts 20, the size and position of the limit bolts 20 correspond to those of the limit holes 21, and the adjusted position can be limited after the overall length of the guardrail is adjusted.

[0029] When in use, the guardrail can be placed in a designated position for normal use. When the overall height of the guardrail needs to be adjusted, the rotating disk 13 is rotated to drive the rotating rod 11 and the second bevel gear 12 to rotate. Since the first bevel gear 10 is meshed with the second bevel gear 12, the first bevel gear 10 and the screw rod 7 can be driven to rotate. Since the extension rod 8 is threadedly connected to the screw 7 and is limited by the slider 16, the extension rod 8 can be driven to rise. During the rising process, the extension rod 8 will drive the first cross plate and the fourth cross plate to rise through the action of the fixing block 14. The first cross plate When the plate and the fourth horizontal plate are raised, the telescopic rod 19 will be driven to rise. After the telescopic rod 19 is extended to a certain extent, the second horizontal plate and the fifth horizontal plate will be driven to rise, and so on, to achieve the effect of adjusting the height. When the protective length of the guardrail needs to be adjusted, loosen the limit bolt 20 to make the first protective plate 4 and the second protective plate 5 lose the fixing effect, and then drive the first column 1 or the second column 2 to move. After the length adjustment is completed, tighten the limit bolt 20 again. The guardrail can adjust the protection height and length according to specific usage requirements, and has strong applicability.
