Some also use bolts and rotating blocks to adjust the angle of the connecting pipe, but the adjusted angle is generally fixed and cannot be adjusted to any angle, which is inconvenient for actual use. Utility Model Content

DETAILED DESCRIPTION

[0021] The technical solution of the utility model will be clearly and completely described below in conjunction with the accompanying drawings and specific embodiments.

[0022] Example 1: Figure 1-4The connection structure shown includes a riser 1, the outer wall of the circumference of the riser 1 is sleeved with an annular block 2, an arc groove is provided on the top of the annular block 2, a movable block 4 is slidably installed in the arc groove, a moving block 5 is installed on the side of the movable block 4, an avoidance hole matched with the moving block 5 is provided on the side of the annular block 2, lower arc connecting pipes 6 are installed on the sides of the annular block 2 and the moving block 5, upper arc connecting pipes 7 are hingedly installed on the two lower arc connecting pipes 6, a fixing frame 10 is installed on the top of the movable block 4, a fixing block 18 is provided on the right side of the riser 1, a movable hole is provided on the top of the fixed block 18, a fixing bolt 19 is movably installed in the movable hole, a plurality of fixed threaded holes matched with the fixing bolts 19 are provided on the top of the annular block 2, and an adjustment mechanism for moving the fixed block 18 is provided on the fixing frame 10.

[0023] By means of the above structure, firstly, the vertical pipe 1 is inserted into one of the steel pipes, and then the other steel pipe is fixed on one of the lower arc-shaped connecting pipes 6 and one of the upper arc-shaped connecting pipes 7, and then the fixing frame 10 is rotated. The movement of the fixing frame 10 causes the movable block 4 to move along the arc groove. The movement of the movable block 4 causes the moving block 5 to move. The movement of the moving block 5 causes the other lower arc-shaped connecting pipe 6 and the upper arc-shaped connecting pipe 7 to move, and then adjust according to the angle of the steel pipe; when the adjustment is completed, the fixing bolt 19 is aligned with one of the fixing threaded holes through the adjustment mechanism, and then the fixing bolt 19 is fixed in the fixing threaded hole. When fixed, the fixing frame 10 cannot move. The inability of the fixing frame 10 to move will make the other lower arc-shaped connecting pipe 6 and the upper arc-shaped connecting pipe 7 unable to move through the movable block 4 and the moving block 5, thereby fixing them, so that they can be rotated to any angle, which is convenient for practical use.

[0024] like Figure 4 As shown, the adjustment mechanism includes a movable groove provided on the inner wall of the side of the fixed frame 10, a screw rod 11 is rotatably installed on the inner wall opposite to the movable groove, one end of the screw rod 11 extends to the outside of the fixed frame 10 and is installed with a first knob, a threaded block 12 is threadedly sleeved on the screw rod 11, a movable frame 14 is installed on the side of the threaded block 12, a movable groove is provided on the inner wall of the side of the movable frame 14, a threaded rod 15 is rotatably installed on the inner wall opposite to the movable groove, avoidance holes are provided on the side of the fixed frame 10 and the side of the movable frame 14, one end of the threaded rod 15 passes through the two avoidance holes in sequence and is installed with a second knob, a threaded block 16 is threadedly sleeved on the threaded rod 15, and a fixed block 18 is installed on the side wall of the threaded block 16. The advantage of such an arrangement is that, through the arrangement of the screw rod 11, the first knob, the threaded block 12, the movable frame 14, the threaded rod 15, the second knob and the threaded block 16, it is convenient to align the fixing bolt 19 with the fixed threaded holes in different positions.

[0025] Specifically, the first knob is turned, and the rotation of the first knob causes the screw rod 11 to rotate, and the rotation of the screw rod 11 causes the threaded block 12 to move, and the rotation of the threaded block 12 causes the moving frame 14 to move, and the movement of the moving frame 14 causes the longitudinal movement of the fixed block 18, thereby changing the longitudinal position of the fixing bolt 19, and then the second knob is turned to cause the threaded rod 15 to rotate, and the rotation of the threaded rod 15 causes the threaded block 16 to move, and the threaded block 16 causes the fixing block 18 to move laterally, and the lateral movement of the fixing block 18 causes the longitudinal position of the fixing bolt 19 to change. The fixing bolt 19 is changed, and then the fixing bolt 19 is aligned with the fixing threaded holes in different positions, and then the fixing bolt 19 is fixed in the fixing threaded holes. At this time, the fixing block 18 is fixed, and the fixing block 18 is fixed, which will make the threaded block 12 and the threaded block 2 16 unable to move, and the threaded block 12 and the threaded block 2 16 unable to move will make the fixing frame 10 unable to move, and the fixed frame 10 unable to move will make one of the lower arc-shaped connecting tubes 6 unable to move through the movable block 4 and the movable block 5, so that one of the lower arc-shaped connecting tubes 6 can be rotated to any angle, which is convenient for actual use.

[0026] like Figure 4 As shown, the relative inner walls of the movable groove and the relative inner walls of the active groove are respectively installed with guide rods 13 and limit rods 17, and the sides of the threaded block 12 and the threaded block 2 16 are provided with guide holes, and the guide rods 13 and the limit rods 17 respectively penetrate the two guide holes. The advantage of this arrangement is that through the arrangement of the guide rods 13 and the limit rods 17, a certain guiding effect is played, so that the threaded block 12 and the threaded block 2 16 move along the horizontal direction.

[0027] Example 2: Figure 1 As shown, fixing plates 8 are installed on the sides of the two lower arc-shaped connecting tubes 6 and the sides of the two upper arc-shaped connecting tubes 7, mounting holes are provided on the tops of the two upper fixing plates 8, locking bolts 9 are movably installed in the two mounting holes, and locking threaded holes are provided on the tops of the two lower fixing plates 8, and the bottom ends of the two locking bolts 9 are respectively threadedly installed in the two locking threaded holes. The advantage of such an arrangement is that, through the arrangement of the fixing plates 8 and the locking bolts 9, the lower arc-shaped connecting tubes 6 and the upper arc-shaped connecting tubes 7 can be opened and closed, thereby facilitating the placement of the scaffolding tubes.

[0028] like Figure 4 As shown, an arc-shaped indicator block 20 is installed on the side of the fixed block 18, and an arc-shaped indicator line 21 adapted to the arc-shaped indicator block 20 is provided on the top of the annular block 2. The advantage of such a setting is that the setting of the arc-shaped indicator block 20 and the arc-shaped indicator line 21 plays a certain indicating role, which facilitates the alignment of the fixing bolt 19 with the fixing threaded hole.

[0029] Example 3: Figure 1As shown, fastening bolts 3 are arranged on the vertical pipe 1, the two lower arc-shaped connecting pipes 6 and the two upper arc-shaped connecting pipes 7. The advantage of such arrangement is that the fastening bolts 3 facilitate the fixing of the scaffolding branch pipes.

[0030] The present application also provides a steel scaffold for construction, comprising vertical poles, horizontal poles and the connection structure of the scaffold.
