[0025] like Figure 1-5 As shown, the folding assembly includes a lower mounting frame 3 and an upper mounting frame 6. The lower mounting frame 3 is fixedly mounted at the axis center of the upper surface of the mounting plate 1. The two sides of the lower mounting frame 3 are symmetrically threaded with first threaded knobs 4, and one end of the two first threaded knobs 4 is fixedly connected to a first plug rod 5. The upper mounting frame 6 is fixedly mounted at the axis center of the lower surface of the base 2. The two sides of the upper mounting frame 6 are symmetrically threaded with second threaded knobs 7, and one end of the two second threaded knobs 7 is fixedly connected to a second plug rod 8. When the angle of the base 2 is deflected under the action of the adjustment assembly, the folding frame 9 will be driven to rotate between the first plug rod 5 and the second plug rod 8, which is more stable when adjusting the angle of the base 2 according to the slope, and the device as a whole is safer and more stable.
[0026] like Figure 1-5 As shown, a folding frame 9 is placed in the inner cavity of the lower mounting frame 3, and first insertion holes 10 for plugging with the second insertion rod 8 and the first insertion rod 5 are symmetrically opened on both sides of the folding frame 9. Due to the use of threaded installation and plug-in methods, the plug-in fixes the folding frame 9, and the threaded connection limits the folding frame 9 after plugging. The overall structure is simple and easy to operate.
[0027] like Figure 1-5 As shown, the inner cavity of the mounting plate 1 is cast with concrete, and the surface of the mounting plate 1 is made of stainless steel. The base 2 is made of rubber. The concrete structure is used to increase the counterweight of the mounting 1. At the same time, the concrete is wrapped with stainless steel to avoid rust and enhance the stability of the base 2. The rubber material has the advantages of good elasticity, wear resistance and corrosion resistance.
[0028] Working principle:
[0029] When in use, the device is first assembled, the second connecting member 17 is threadedly installed in the second threaded mounting hole 12 through the second threaded rod 18, and the first connecting member 13 is threadedly installed in the first threaded mounting hole 11 through the first threaded rod 14. Then, the folding frame 9 is vertically placed in the inner cavity of the upper mounting frame 6 and the lower mounting frame 3, and the first threaded knob 4 is rotated forward, and the first threaded knob 4 is threadedly rotated in the lower mounting frame 3 and drives the first insertion rod 5 to be inserted into the first insertion hole 10 at the upper end, and the second threaded knob 7 is rotated forward, and the second threaded knob 7 is threadedly rotated in the upper mounting frame 6 and drives the second insertion rod 5 to be inserted into the first insertion hole 10 at the upper end. The rod 8 is inserted into the first plug hole 10 at the lower end for positioning. The installation position of the guardrail base can be a plane or a slope. When installing on a slope, the sleeve rod 22 is rotated in the main rod 21 to adjust the length of the main rod 21 and the sleeve rod 22 to adjust the angle of the base 2. When the mounting plate 1 is installed on the slope, the base 2 is always in a horizontal position, which is convenient for installing the guardrail. At the same time, when the angle of the base 2 is deflected, the folding frame 9 will be synchronously driven to fold and provide support for it as a whole. The utility model has a simple overall structure and is easy to operate, and is suitable for large-scale promotion.
