fixed.
Through the mesh of the road cone, fill the pot with the fine river sand and use it.
Buy a stainless steel hollow ball with a diameter of 280nn and cut it 3/5 for use.
A steel tube having a diameter of 22 nm and a length of 80 nn was inserted through the center of the hemispherical cross section.
Two parallel steel pipes are welded on the cross section to clamp the upright steel pipe.
Weld 400nn steel sheets on the upper part of the vertical steel pipe and put a 500x 300nn rectangular plywood brand. Put the word 'no smoking' on the sign, 'the road construction vehicle is slowâ€
Place the tumbler warning sign in a public place, road maintenance office; place the signboard at the door of the store, hotel, etc.
The tumbler's warm reminder card and billboard will weld a square tube with a length of 22nn into a rectangular frame with a size of 320x220nn% and a fixed beam parallel to the long side at the center of the wide side.
With a wide side as the end point, a semi-circular arched steel skin is welded, and the steel skin is welded on both sides to make it a whole tumbler base.
On the central fixture, two 800 ng vertical steel tubes were welded at a parallel distance of 220 nm, and the lower end was inserted into the bottom of the base.
At the upper end of the two vertical tubes, make 600x400nn cards to be printed, plant a small tree and harvest a green shade.
In the process of production, I used the mechanics of the tumbler; organically integrated the tumbler with the erect objects such as billboards, signboards, warning signs, warm reminders, road cones, etc., so that various cards and road cones were outdoors, in the wild, On the road, if the wind blows the rain, the vehicles gallop, and will not be affected by the swing and then recover, then they can stand in the land, stick to the post and play a role.
For those relatively large and heavy brands, I plan to use the tumbler combination group to make it stronger and more stable and not easy to fall.
