[0018] like Figure 1-2As shown, a building security guardrail includes a storage tube 1, which is hollow and cylindrical, and the outer wall of the storage tube 1 is provided with a pull-out opening 2. It also includes a connecting frame 3, an expansion mechanism 4 and a protective mechanism 5. The connecting frame 3 is fixedly connected to the outer wall of the storage tube 1, and the connecting frame 3 is a long rectangular frame. A slide groove 6 is formed inside the connecting frame 3. The expansion mechanism 4 is slidably arranged in the slide groove 6 and can be pulled and rotated along the length direction of the connecting frame 3 for adjusting the length and angle of the expansion mechanism 4. The protective mechanism 5 is arranged inside the storage tube 1 and is pulled out synchronously with the expansion mechanism 4 to increase the protection density of the connecting frame 3 and the expansion mechanism 4.

[0019] like Figure 1 and Figure 4 As shown, in order to achieve length expansion and angle adjustment of the device, the expansion mechanism 4 includes a limiting tube 7, a connecting plate 8 and a pulling tube 9. The limiting tube 7 passes through the connecting frame 3 and is slidably arranged in the slide groove 6. One end of the connecting plate 8 is fixedly connected to the outer wall of the limiting tube 7. The pulling tube 9 is fixedly connected to the other end of the connecting plate 8. The connecting frame 3 and the connecting plate 8 are staggered with the limiting tube 7 as the center. The limiting tube 7 is connected to the connecting plate 8 and slides in the slide groove 6 at the same time. The pulling tube 9 is pulled to make the connecting plate 8 slide out of the connecting frame 3 to increase the protection length. The connecting plate 8 is rotated and adjusted in the slide groove 6 with the limiting tube 7 as the center to generate an angle between the connecting plate 8 and the connecting frame 3, thereby realizing the angle adjustment of the guardrail and performing bending enclosure.

[0020] like Figure 1-4 As shown, in order to increase the protection effect of the device, after the enclosure, the floating or dust flowing in the air is filtered to reduce its flow and purify the environment. The protection mechanism 5 includes a rotating shaft 10, a turbine coil spring 11 and a protective net 12. The turbine coil spring 11 is fixedly connected to the center of the inner upper wall and the inner bottom wall of the storage tube 1. The turbine coil spring 11 is symmetrically arranged up and down. The two ends of the rotating shaft 10 are fixedly connected to the center of the symmetrical turbine coil spring 11. One end of the protective net 12 is fixedly connected to the outer side wall of the rotating shaft 10, and the other end of the protective net 12 is fixedly connected to the outer side wall of the pulling tube 9. The protective net 12 is fixed between the rotating shaft 10 and the side wall of the pulling tube 9. When the pulling tube 9 is pulled and moved, the protective net 12 rolled up on the outside of the rotating shaft 10 is unfolded. Under the rolling action of the turbine coil spring 11, the protective net 12 is attached to one side of the connecting frame 3 and the connecting plate 8 and is in a tensioned state. The protective net 12 filters the flowing air.

[0021] Among them, a positioning column 13 is provided inside the pull-out tube 9, and the positioning column 13 is threadedly connected to the inner wall of the pull-out tube 9.

The positioning column 13 and the positioning column 2 14 are respectively rotated in the limiting tube 7 and the pull-out tube 9 and extended downward so that the bottom of the positioning column is inserted into the soil, so as to position and install the midpoint and the extended end of the device.

[0022] When in use, the operator places the device in the construction area. In the initial state, the device is in a retracted state, the protective net 12 is in a semi-retracted state, the limit tube 7 is close to the storage tube 1, and the connecting plate 8 and the connecting frame 3 are in the same plane and arranged in a staggered manner;

[0023] When in use, pull the pull-out tube 9 to slide the connecting plate 8 out of the connecting frame 3 to increase the protection length. The connecting plate 8 is rotated and adjusted in the slide groove 6 with the limiting tube 7 as the center to generate an angle between the connecting plate 8 and the connecting frame 3 to achieve the angle adjustment of the guardrail and perform bending enclosure;

[0024] At the same time, the protective net 12 is fixed between the rotating shaft 10 and the side wall of the drawing tube 9. When the drawing tube 9 is pulled and moved, the semi-rolled protective net 12 is unfolded. Under the winding action of the turbine coil spring 11, the protective net 12 is attached to one side of the connecting frame 3 and the connecting plate 8 and is in a taut state. The protective net 12 filters the flowing air.

[0025] Finally, the positioning column 13 and the positioning column 2 14 are rotated so that the bottoms thereof are inserted into the soil, and the midpoint and the extended end of the device are positioned and installed.
