Multi-angle adjustable scaffold steel tube and steel tube scaffold
The invention provides a multi-angle adjustable scaffold steel tube and a steel tube scaffold. The steel tube is a cross rod or a horizontal inclined rod and further comprises lock heads, connecting pieces, socket-and-spigot substrates and connecting parts. The lock heads are flat, a long groove is formed in the middle of each lock head, and through holes are symmetrically formed in the two sides of each lock head. One end of each connecting piece is embedded into the long groove of the corresponding lock head and provided with a second through hole corresponding to the corresponding through hole, and the other end of each connecting piece is connected with the corresponding socket-and-spigot substrate. The tail ends of the socket-and-spigot substrates are connected with the connecting pieces, the head ends of the socket-and-spigot substrates comprise conical grooves, the inner portions of the conical grooves are narrower than the outer portions of the conical grooves, the upper portions of the conical grooves are narrower than the lower portions of the conical grooves, and the direction of the conical grooves is parallel to the direction of the connecting pieces. The connecting parts connect the through holes and the second through holes in a penetrating mode, the cross rod or the horizontal inclined rod and the socket-and-spigot substrates can relatively move with the connecting parts as pivots. According to the scaffold steel tube, the length and the angle can be adjusted, the angle adjusting activity range is wide, and the length is flexibly, easily and conveniently adjusted. The steel tube scaffold is high in overall stability, simple in structure, convenient to install and detach, safe and reliable.
