[0024] A safety protection device for construction engineering, comprising a fixed frame 1 and a fixing mechanism 4, wherein support columns 2 are slidably mounted on both sides of the fixed frame 1, and a telescopic mechanism 3 is provided between the support columns 2 and the fixed frame 1;

[0025] The telescopic mechanism 3 includes two sets of connecting plates 31, one of which is slidably mounted inside the fixed frame 1, and the other set of connecting plates 31 is fixedly mounted on one side of the support column 2. A telescopic frame 32 is provided between the two sets of connecting plates 31. Sleeves 33 are fixedly mounted on the upper and lower sides of the telescopic frame 32 of the two sets of connecting plates 31. A set of sliding plates 34 is inserted into the two sets of sleeves 33 arranged opposite to each other.

[0026] There are four groups of fixing mechanisms 4, two of which are installed on one side of the fixing frame 1, and the other two groups are installed on one side of the two groups of support columns 2, respectively, so as to facilitate the installation and fixation of the fixing frame 1 and the support columns 2 through the fixing mechanisms 4.

[0027] The fixing mechanism 4 includes a fixing plate 41, on which a screw 42 is threadedly connected, a spiral cone rod 43 is fixedly connected to the bottom of the screw 42, and an adjusting knob 44 is fixedly connected to the top of the screw 42, so that the screw 42 can be rotated by turning the adjusting knob 44, so that the spiral cone rod 43 at the bottom of the screw 42 moves downward and is screwed into the soil, thereby installing and fixing the device.

[0028] It also includes a circular limit plate 45, which is fixedly sleeved on the bottom outer wall of the screw 42. The top of the circular limit plate 45 is movably connected to the bottom of the fixed plate 41, so that the number of rotations of the screw 42 can be limited by the circular limit plate 45.

[0029] Both ends of the telescopic frame 32 are rotatably connected with two sets of fixing sleeves 35. The four sets of fixing sleeves 35 are respectively fixedly installed on the opposite sides of the two sets of connecting plates 31, so that the telescopic frame 32 can be telescopically installed between the two sets of connecting plates 31 through the cooperation of the four sets of fixing sleeves 35.

[0030] Two groups of first magnetic blocks 7 are fixedly installed on the inner walls on both sides of the fixed frame 1, and two groups of connecting plates 31 are fixedly installed on the side away from the support column 2 with second magnetic blocks 8 corresponding to the first magnetic blocks 7. The first magnetic blocks 7 and the second magnetic blocks 8 are magnetically connected, so that the telescopic mechanism 3 can be limited and fixed inside the fixed frame 1 through the magnetic cooperation between the first magnetic blocks 7 and the second magnetic blocks 8.

[0031] It is worth noting that when the first magnetic block 7 and the second magnetic block 8 are magnetically attracted, one side of the support column is in contact with the fixing frame 1 .

[0032] The upper and lower ends of the two groups of connecting plates 31 located inside the fixed frame 1 are slidably inserted with the limiting long plates 6, and the inner top and inner bottom of the fixed frame 1 are provided with limiting slide grooves 5. The two groups of limiting long plates 6 are respectively fixedly installed inside the two groups of limiting slide grooves 5, so as to facilitate the limiting of the connecting plates 31 in the fixed frame 1 by the limiting long plates 6.

[0033] A reflector 9 is provided on one side of the fixing frame 1 , and a warning slogan is provided on the reflector 9 to warn pedestrians.

[0034] Working principle: When the present invention is used, the fixing frame 1 is first installed and fixed through the fixing mechanism 4, and then the telescopic mechanism 3 is pulled out from the inside of the fixing frame 1 by pulling the support column 2, and the telescopic frame 32 in the telescopic mechanism 3 is telescoped and stretched. At the same time, the sleeve 33 on the connecting plate 31 cooperates with the sliding plate 34 to slide, and the limiting long plate 6 in the limiting slide groove 5 limits the connecting plate 31 in the fixing frame 1, and the distance between the support column 2 and the fixing frame 1 can be adjusted. The support column 2 is installed and fixed through the fixing mechanism 4, which has the advantage of simple and convenient adjustment. After use, the telescopic mechanism 3 can be retracted into the inside of the fixing frame 1 by pushing the support column 2 toward the fixing frame 1. The first magnetic block 7 and the second magnetic block 8 cooperate with magnetic attraction to limit and fix the telescopic mechanism 3 inside the fixing frame 1, so that the device is easy to store after use, reducing storage space and facilitating transfer and transportation.
