During installation, expansion bolts and other tools are used to connect the bottom of the column to the ground. This installation method is relatively stable on hard ground. When used on muddy or sandy ground, the expansion bolts are short and the column cannot be stably connected to the ground, so the construction guardrail is prone to tilt and fall. In response to the above problems, an innovative design is carried out based on the original construction guardrail. Utility Model Content

[0032] See also Figure 1-6 The utility model provides a technical solution: a construction guardrail, including a fence 1, a mounting ear 2, a holder 3, a first mounting hole 4, a locking bolt 5, a locking nut 6, a second mounting hole 7, a side column 8, an adjusting sleeve 9, a positioning anchor rod 10, a stabilizing block 11, a limiting plate 12, an outer sleeve 13, a side bolt 14, a support rod 15, a magnet block 16, a base plate 17 and a mounting window 18, the mounting ear 2 is fitted with the inner wall of the holder 3, the mounting ear 2 and the holder 3 are symmetrically distributed about the center of the fence 1, the center of the holder 3 and the center of the side column 8 are on the same vertical plane, the center of the holder 3 is provided with a first mounting hole 4, a locking bolt 5 is installed through the first mounting hole 4, a locking nut 6 is installed at the end of the locking bolt 5, the locking bolt 5 passes through the second mounting hole 7, and the second mounting hole 7 is provided at the center of the mounting ear 2;

[0033] The holder 3 is fixedly installed on the outer wall of the side column 8, and the pre-laid adjustment sleeve 9 is rotatably installed on the top of the side column 8 through the bearing seat. The bottom of the adjustment sleeve 9 is connected to the top of the positioning anchor rod 10. A stabilizing block 11 is fixedly installed in the middle of the positioning anchor rod 10. The side of the stabilizing block 11 is in contact with the inner wall of the side column 8. A limiting plate 12 is fixedly installed on the inner wall of the side column 8 below the stabilizing block 11. The hole opened in the center of the limiting plate 12 is in contact with the positioning anchor rod 10.

[0034] An outer sleeve 13 is sleeved on the outside of the side column 8, and a side bolt 14 is installed on the side of the outer sleeve 13. A support rod 15 is rotatably installed on the back of the outer sleeve 13. A magnet block 16 is fixed to the front side of the middle of the support rod 15. The magnet block 16 is in contact with the surface of the side column 8, and a base plate 17 is rotatably installed on the bottom end of the support rod 15.

[0035] The front view cross-sectional shape of the adjusting sleeve 9 in this example is a "T" shape, and the length of the adjusting sleeve 9 is greater than 1 / 3 of the length of the side column 8. The side column 8 is a hollow square tube. The above structural design enables the adjusting sleeve 9 to be stably installed and conveniently rotated, and ensures the length connected to the positioning anchor rod 10.

[0036] The surface of the positioning anchor rod 10 in this example is provided with threads, and the positioning anchor rod 10 is threadedly connected to the adjusting sleeve 9. A sharp conical structure is provided at the bottom end of the positioning anchor rod 10. The above structural design enables the adjusting sleeve 9 to utilize the threaded connection relationship to drive the positioning anchor rod 10 to move vertically downward and penetrate into the ground when rotating.

[0037] The positioning anchor rod 10 in this example passes through the center of the stabilizing block 11. The top-view cross-sectional shape of the stabilizing block 11 is a rectangle. The distance from the bottom end of the stabilizing block 11 to the top surface of the limiting plate 12 is smaller than the length of the connecting portion between the positioning anchor rod 10 and the adjusting sleeve 9. The hole opened in the center of the positioning anchor rod 10 and the limiting plate 12 is a sliding connection. The above-mentioned structural design enables the positioning anchor rod 10 to only move vertically downward along the inner wall of the side column 8 with the stabilizing block 11 under the rotation drive of the adjusting sleeve 9, and will not separate from the adjusting sleeve 9.

[0038] In this example, side bolts 14 are symmetrically threadedly installed on both sides of the outer sleeve 13, and the inner wall of the outer sleeve 13 is tightly fitted with the outer wall of the side column 8. The above structural design enables the working position of the outer sleeve 13 to be conveniently adjusted and fixed.

[0039] The length of the support rod 15 in this example is not less than half of the overall length of the side column 8, and the side column 8 is symmetrically distributed about the center of the fence 1. The above structural design enables the support rod 15 to stably support the side column 8 after rotation and tilting, thereby ensuring the stability of the side column 8 and the fence 1.

[0040] In this example, the base plate 17 is provided with installation windows 18 symmetrically distributed about the center of the base plate 17 . The above structural design enables the base plate 17 to be connected to the ground through a fixing tool, thereby improving the supporting and positioning effect of the base plate 17 and the support rod 15 .

[0041] Working principle: When in use, first insert the mounting ear 2 on the side of the fence 1 into the holder 3, use the locking bolt 5 to pass through the first mounting hole 4 and the second mounting hole 7, and install the locking nut 6 at the end of the locking bolt 5 to connect and fix the fence 1 to the side column 8;

[0042] Then step on the bottom of the side column 8 and rotate Figure 3 The adjusting sleeve 9 in the middle drives the positioning anchor rod 10 to slide vertically along the inner wall of the side column 8 with the stabilizing block 11 by means of the threaded connection relationship. The positioning anchor rod 10 moves steadily downward along the central hole of the limiting plate 12 until the bottom end of the stabilizing block 11 contacts the top surface of the limiting plate 12. The adjusting sleeve 9 cannot continue to rotate. The bottom end of the positioning anchor rod 10 penetrates into the ground to a sufficient depth. The adjusting sleeve 9 also locks the positioning anchor rod 10 by means of thread self-locking.

[0043] Then dial Figure 4 The support rod 15 in the middle rotates clockwise to separate the magnet block 16 from the side column 8 containing the metal ferromagnetic material, release the fixation, and move the outer sleeve 13 downward to rotate the base plate 17 so that the base plate 17 fits with the ground surface. The inclination angle of the support rod 15 is appropriate. The rotationally symmetrically distributed side bolts 14 squeeze the outer wall of the side column 8 to fix the working height of the outer sleeve 13. A steel chisel is used to penetrate the installation window 18 and penetrate into the ground to connect the base plate 17 to the ground. The base plate 17 and the support rod 15 support the side column 8 to ensure the stable use of the entire device.

[0044] The above description is only a preferred embodiment of the present invention and is not intended to limit the protection scope of the present invention.
