Description

Technical Field

[0001] The utility model relates to the technical field of construction fences, and more particularly to an assembled construction safety fence. Background Art

[0002] Prefabricated construction safety fences are important safety facilities at prefabricated building construction sites. They are used to isolate the construction site from the external environment, forming a relatively closed space to ensure construction safety.

[0003] In the prior art, most construction fences are arranged side by side to enclose the construction site. In order to facilitate handling and transportation, the fences are set independently of each other. Therefore, during assembly, bolts are usually used for fixing. However, fixing the fences with bolts requires tightening the bolts one by one, which is not only time-consuming and labor-intensive, but also increases the complexity of the installation process. For this reason, we propose an assembled construction safety fence. Utility Model Content

[0024] Both ends of the two rotating shafts 6 are fixedly connected to the mounting plates 5, the outer walls of the mounting plates 5 are fixedly connected to the fixed frame 1, and both ends of the two rotating shafts 6 are sleeved with torsion springs 7. The outer walls of the circumferences of the two rotating shafts 6 are rotatably connected with the first clamping block 8 and the second clamping block 9. One end of the two torsion springs 7 located on the same rotating shaft 6 is fixedly connected to the corresponding mounting plates 5 respectively, and the other ends of the two torsion springs 7 located on the same rotating shaft 6 are fixedly connected to the first clamping block 8 and the second clamping block 9 respectively. A first card slot 10 is provided on the side where the first clamping block 8 and the second clamping block 9 are relatively close, and the card sleeve 4 is snap-fitted with the inner wall of the first card slot 10. A second card slot 13 is provided on the inner wall of the first card slot 10. The outer wall of the circumference of the card sleeve 4 is fixedly connected with two clamping plates 12, and the card plates 12 are snap-fitted with the inner walls of the second card slot 13 respectively. This design can quickly splice two adjacent fences, thereby reducing the complexity of fence splicing and improving installation efficiency.

[0025] like Figure 3 As shown, the opposite ends of the first clamping block 8 and the second clamping block 9 are provided with inclined surfaces 11, and the edges of the ends of the first clamping block 8 and the second clamping block 9 are provided with arc surfaces 14, which are tangent to the inclined surfaces 11.

[0029] By knocking on the tray 24, the bottom of the insertion rod 23 is inserted into the soil, thereby fixing the fence. When dismantling, by stepping on the anti-slip groove 29 on the rocker 28, the rocker 28 presses the extension rod 25 upward, so that the insertion rod 23 is pulled out from the soil, thereby quickly dismantling the fence;

[0030] By holding the handle 21 and pushing the connecting rod 3 upward, the connecting rod 3 drives the clamping sleeve 4 to slide upward along the inner wall of the first clamping groove 10 until the clamping sleeve 4 drives the clamping plate 12 to move out from the inside of the second clamping groove 13. By moving the fence to one side, the connecting rod 3 slides into the inside of the arc groove 15 and squeezes the inner wall of the arc groove 15.
