Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model. Example

[0022] like Figure 1-4 As shown, a safety protection device for construction engineering that is easy to adjust includes a baffle 1 and a rotating seat 2. The number of the rotating seats 2 is four. The inner side wall of the rotating seat 2 is rotatably connected to a rotating shaft 3, and the middle part of the outer surface of the rotating shaft 3 is fixedly connected to an inclined rod 4;

[0023] In this embodiment, one end of the inclined rod 4 is rotatably connected to a contact plate 5 , and the upper surface of the rotating seat 2 is threadedly connected to a bolt 6 .

[0024] During specific use, the rotating shaft 3 and the rotating seat 2 have a rotating effect. After loosening the bolt 6, the inclined rod 4 can be directly flipped to make the contact plate 5 close to the ground. After tightening the bolt 6 again, the rotating shaft 3 is fixed in turn. Through the four groups of contact plates 5, it is close to the ground. When the protective device is blown by side wind, the risk of being blown over can be effectively reduced, thereby greatly increasing the firmness.

[0025] In this embodiment, a bottom plate 7 is fixedly connected to the lower surface of the baffle 1 , a self-locking wheel 8 is rotatably connected to the lower surface of the bottom plate 7 , and the bottom plate 7 is fixedly connected to the rotating seat 2 .

[0026] When the protective device is used specifically, the self-locking wheel 8 has the function of facilitating movement when it is necessary to move the protective device.

[0027] In this embodiment, a vertical plate 9 is fixedly connected to one side of the upper surface of the bottom plate 7 , and a movable plate 10 is slidably connected to the inner side wall of the vertical plate 9 .

[0028] When in use, the movable plate 10 has a sliding effect in the vertical plate 9, so that the movable plate 10 can slide up and down, which is convenient for adjusting the height.

[0029] In this embodiment, a tooth groove 11 is formed on the back of the movable plate 10 , and a limit block is fixedly connected to the lower surface of the movable plate 10 .

[0030] During specific use, the meshing effect of the tooth groove 11 and the active tooth 13 is utilized to facilitate the movable plate 10 to be subjected to an acting force, and the limit block can prevent the movable plate 10 from sliding out excessively.

[0031] In this embodiment, a transmission rod 12 is rotatably connected to one side of the vertical plate 9, one end of the transmission rod 12 passes through one side of the vertical plate 9 and extends to the other side of the vertical plate 9, and an active tooth 13 is fixedly connected to the outer surface of the transmission rod 12, and the active tooth 13 is meshed with the tooth groove 11.

[0032] When in use, the meshing effect of the active teeth 13 and the tooth grooves 11 is utilized, and the movable plate 10 has a sliding effect in the vertical plate 9, so that the active teeth 13 rotate and drive the movable plate 10 to move upward.

[0033] In this embodiment, one end of the transmission rod 12 is fixedly connected to a handle 14 , and one side of the handle 14 is plugged with a cross bar 15 .

[0034] When the height of the protective device needs to be adjusted during use, the driving gear 13 can be rotated by rotating the transmission rod 12 through the handle 14 .

[0035] In this embodiment, a slot 16 is formed on one side of the outer surface of the vertical plate 9 , and the size of the slot 16 is adapted to the cross bar 15 .

[0036] When in use, after adjustment, the cross bar 15 is inserted into the slot 16 to temporarily fix the handle 14 to prevent the transmission rod 12 from rotating.

[0037] Working principle: During use, after pushing the installed protective device to the position where it needs to be placed, the rotating shaft 3 and the rotating seat 2 have a rotating effect. After loosening the bolt 6, the inclined rod 4 can be directly flipped to make the contact plate 5 close to the ground. After tightening the bolt 6 again, the rotating shaft 3 is fixed in turn, and the four groups of contact plates 5 are close to the ground. When the protective device is blown by the side wind, the risk of being blown over can be effectively reduced, thereby greatly increasing the firmness. When the height of the protective device needs to be adjusted, the transmission rod 12 is rotated by the handle 14 to rotate the active tooth 13, and the meshing effect of the active tooth 13 and the tooth groove 11 is utilized. At the same time, the movable plate 10 has a sliding effect in the vertical plate 9, so that the active tooth 13 drives the movable plate 10 to move upward after rotating. After the transmission rod 12 is rotated in the opposite direction, the movable plate 10 can move downward, thereby adjusting the height of the protective device. After adjustment, the cross bar 15 is inserted into the card slot 16, and the handle 14 can be temporarily fixed to prevent the transmission rod 12 from rotating, which has the effect of quick fixing.
