Referring to Figures 1-5, a foldable movable guardrail includes a first plate 1 and a connecting plate 3, the bottom of the outer walls on both sides of the first plate 1 are welded with fixed plates 18, and the two ends of the outer walls of the bottom of the two fixed plates 18 are connected to each other. Have fixing hole 19, after the position of guardrail is adjusted, guardrail can be fixed on the ground by fixing hole 19, and connecting plate 3 one side outer walls are fixed with handle 20, and connecting plate 3 one side outer walls both ends are provided with screw thread After the through hole 21 and the connecting plate 3 are put into the long groove, the two threaded through holes 21 are respectively aligned with the first threaded hole 12 and the second threaded hole 14, and at this time, bolts can be screwed into the two threaded through holes 21. , the connecting plate 3, the first plate 1 and the second plate 2 are fixedly connected, and the handle 20 provided is convenient for pulling the guardrail to move;

One end of the top outer wall of the first plate 1 is hinged with the second plate 2, the outer wall on one side of the first plate 1 has a first groove 11, the inner wall on one side of the first groove 11 has a first threaded hole 12, and the outer wall on one side of the second plate 2 There is a second groove 13, and the inner wall of the second groove 13 has a second threaded hole 14. After the second plate 2 stands on the first plate 1, the second groove 13 is connected with the first groove 11 to form a At this time, the connecting plate 3 can be put into the long groove and fixed in the long groove, and then the first plate 1 and the second plate 2 are fixedly connected to keep the vertical state;

The outer wall of the bottom of the first plate 1 has a groove 4, and the middle part of the inner wall of the top of the groove 4 has a mounting groove 5. The inner wall of the mounting groove 5 is fixed with a mounting plate 6, and the outer wall of the top of the mounting plate 6 is inserted with a threaded rod 7 through a bearing. The outer wall of one side of the plate 1 is inserted with a rotating rod 8 through a bearing, the first bevel gear 9 is fixed on one end of the rotating rod 8, the second bevel gear 10 is fixed on the top end of the threaded rod 7, the first bevel gear 9 and the second bevel gear 10 Mesh with each other, the rotation of the rotating rod 8 drives the first bevel gear 9 to rotate, the rotation of the first bevel gear 9 drives the rotation of the second bevel gear 10, and the rotation of the second bevel gear 10 drives the rotation of the threaded rod 7;

Threaded rod 7 is screwed with moving mechanism, and moving mechanism comprises slide block 15, is fixed on the support plate 16 of slide block 15 bottom outer wall two ends, is fixed on the lift plate 17 on the bottom outer wall of two support plates 16, is fixed on lift plate 17 The moving wheels at the four corners of the outer wall of the bottom, after the threaded rod 7 rotates, the slider 15 is affected by the limit of the installation groove 5, and does not rotate together with the threaded rod 7, but moves up or down along the inner wall of the installation groove 5, which can be adjusted by adjusting the threaded rod 7 The direction of rotation makes the slider 15 move downward, and then drives the support plate 16, the lifting plate 17 and the moving wheel to move downward, the moving wheel contacts the ground, and props up the first plate 1, which can push the guardrail to move as a whole ;

By dividing the guardrail as a whole into two parts, the foldable first board 1 and the second board 2, the second board 2 only needs to be erected during construction, which is easy and labor-saving, and the first board 1 is connected through the connecting board 3 It is fixed together with the second plate 2 to complete the construction of the guardrail, which is convenient and quick. When it is necessary to move and adjust the position of the erected guardrail, you only need to turn the rotating rod 8, and the rotation of the rotating rod 8 drives the threaded rod 7 to rotate. , let the moving mechanism screwed on the threaded rod 7 move downward, so that the moving wheels in the moving mechanism contact the ground, and the first plate 1 is propped up, at this time the whole guardrail can be pushed to move, which is convenient for moving and The adjusted position is spliced together with other guardrails. After the position is adjusted, the moving mechanism can be raised again so that the bottom of the first board 1 contacts the ground for easy fixing.

Working principle: By dividing the guardrail into two parts, the foldable first board 1 and the second board 2, only the second board 2 needs to be erected during construction, and the second board 2 stands on the first board 1 Finally, the second groove 13 is connected with the first groove 11 to form a long groove. At this time, the connecting plate 3 can be put into the long groove. After the connecting plate 3 is put into the long groove, the two threaded through holes 21 are respectively connected with The first threaded hole 12 is aligned with the second threaded hole 14, and at this moment, bolts can be screwed into the two threaded through holes 21, and the connecting plate 3, the first plate 1 and the second plate 2 are fixedly connected and kept vertical Status, complete the construction of the fence;

When it is necessary to move and adjust the position of the erected guardrail, the rotating rod 8 can be rotated, the rotating rod 8 rotates to drive the first bevel gear 9 to rotate, the first bevel gear 9 rotates to drive the second bevel gear 10 to rotate, and the second bevel gear 10 The rotation drives the threaded rod 7 to rotate. After the threaded rod 7 rotates, the slider 15 is affected by the limit of the installation groove 5, and does not rotate together with the threaded rod 7, but moves up or down along the inner wall of the installation groove 5. It can be adjusted by adjusting the threaded rod. 7 The direction of rotation makes the slider 15 move downward, and then drives the support plate 16, the lifting plate 17 and the moving wheel to move downward, the moving wheel contacts the ground, and props up the first plate 1, which can push the guardrail to move as a whole After the position is adjusted, the rotating rod 8 can be rotated in the opposite direction again to raise the moving wheel, so that the bottom of the first plate 1 contacts the ground, and the guardrail is fixed on the ground through the fixing hole 19.
