In the assembled state, the right protective rod 6 and the left protective rod 13 are both in a horizontal state and the ends are connected by the connecting mechanism.

[0027] Embodiment 2

[0028] like Figure 1-Figure 4 As shown, a construction protection device proposed by the present invention, compared with the first embodiment, this embodiment introduces in detail the rotation structure of the right protection rod 6 and the left protection rod 13.

[0029] Vertical grooves 3 are arranged on the left and right sides of the support column 2. The vertical grooves 3 form openings on the top surface of the support column 2. The tops of the right protective rod 6 and the left protective rod 13 are rotatably connected to the inner walls of the two vertical grooves 3 respectively. In an optional embodiment, the support column 2 is directly an I-beam, and there is no need to open the vertical grooves 3, which makes the processing simpler.

By adjusting the diameters of the right shaft 4 and the rotational fittings a5, a certain rotational friction force is generated on the right shaft 4, so that the right shaft 4 can be stopped at a required angle, and one person can perform the assembly without one person holding the right protection bar 6 and another person connecting the right protection bar 6 and the left protection bar 13. It is more convenient to use. Similarly, by adjusting the diameter of the left rotating shaft 11 and the rotating matching piece b12, a certain rotational friction force is created for the left rotating shaft 11, so that the left rotating shaft 11 can stop at a required angle. During production and processing, the two ends of the right rotating shaft 4 are first inserted into the two rotating matching pieces a5, and then the two rotating matching pieces a5 are connected to the wall of the vertical groove 3, such as by welding. Similarly, the two ends of the left rotating shaft 11 are first inserted into the two rotating matching pieces b12, and then the two rotating matching pieces b12 are connected to the wall of the vertical groove 3.

When the right protective rod 6 is in a tilted storage state, the upper right protective rod 6 cooperates and snaps into the elastic arc clamp a9 on the next right protective rod 6; an elastic arc clamp b17 is provided on the left protective rod 13. When the left protective rod 13 is in a tilted storage state, the upper left protective rod 13 cooperates and snaps into the elastic arc clamp b17 on the next left protective rod 13; by providing the elastic arc clamp a9 and the elastic arc clamp b17, the shaking of the right protective rod 6 and the left protective rod 13 can be reduced in the storage state, thereby improving the stability of the entire structure; in order to further reduce the storage size, avoidance grooves 10 are provided on both sides of the base 1, and the lowermost right protective rod 6 and the left protective rod 13 are both received in the avoidance grooves 10.

[0035] Embodiment 4

[0036] like Figure 2-Figure 4 As shown, a construction protection device proposed by the present invention, compared with the first embodiment, the second embodiment or the third embodiment, this embodiment introduces the structure of the connecting mechanism in detail.

[0037] The connecting mechanism includes a connecting rod 7 arranged on the outer peripheral surface of the bottom of the right protective rod 6 and a limiting plate 8 arranged at the end of the connecting rod 7, and the diameter of the limiting plate 8 is larger than the diameter of the connecting rod 7; a semicircular notch 14 is arranged at the bottom of the left protective rod 13, and the outer diameter of the right protective rod 6 is smaller than the inner diameter of the left protective rod 13. The right protective rod 6 is inserted into the left protective rod 13 through the notch 14, and the left protective rod 13 is provided with a through hole 15 for the limiting plate 8 to pass through and a limiting groove 16 for the connecting rod 7 to slide.

[0038] In summary, when the utility model is in use, the right protective rod 6 and the left protective rod 13 are straightened and connected, and the base 1 is fixed. When not in use, the base 1 is first released, and then the base 1 is pulled inward laterally to move the limit plate 8 to the position of the through hole 15, and then the base 1 is pushed longitudinally to make the limit plate 8 pass through the through hole 15. At this time, the right protective rod 6 and the left protective rod 13 have been separated, and then the right protective rod 6 and the left protective rod 13 are flipped downward. The inclined right protective rod 6 and the left protective rod 13 occupy very little space, which is conducive to storage and transportation.
