[model utility content]
The utility model provides for the problem that solves above-mentioned prior art and exist that a kind of not only processing is simple, cost is low and simple in structure, but also reels because of electric wire can avoid outer sleeve with the inner sleeve rotation time and the multi-joint telescoping cylinder of the disconnected electric leakage accident generation that causes of strand.
For achieving the above object, the utility model provides a kind of multi-joint telescoping cylinder, it comprises base, be installed on the outer sleeve on base top, be installed on big by diameter successively in the outer sleeve to little a plurality of inner sleeves, it is inner and place the interior base of inner sleeve outer surface to be installed on outer sleeve, be installed on outer sleeve upper and place the fixed base of inner sleeve lower end, described fixed base comprises fixed cover, be installed on the wedge type block in the fixed cover, be installed on the following stick harness head of fixed cover outside, be installed on down the bolt of stick harness end surface and be installed on bolt and following stick harness head between intermediolateral column; Be respectively arranged with groove on the two side of described inside and outside sleeve pipe.
According to above-mentioned major technique feature, described fixed cover is cylindrical body, is respectively equipped with big ladder mouth in the both sides of this cylindrical body inside, is provided with little ladder mouth in the lower end of this big ladder mouth, be provided with the rectangular indentation of annular in the upper end of this big ladder mouth, be provided with fixed hole in a cylindrical side.
According to above-mentioned major technique feature, described wedge type block is rectangular, is provided with the plane of inclination at this rectangular end, and the dorsal part in this plane of inclination is provided with breach.
According to above-mentioned major technique feature, described stick harness head down is annulus, extends the convex column of a protrusion at an end of this annulus, is provided with perforation in the inside of the other end of this convex column.
Useful technique effect of the present utility model: because of on the two side of described inside and outside sleeve pipe, being respectively arranged with groove and wedge type block cooperatively interacts, make it avoid in the process of outer sleeve and inner sleeve rotation, because of electric wire is reeled, the disconnected electric leakage accident that causes of strand.Compare with existing fixed base, the fixed base in the utility model in the multi-joint telescoping cylinder has processes simple, low cost of manufacture and simple in structure.
For purpose, structure characteristics and function thereof to model utility have further understanding, conjunction with figs. is described in detail as follows now:
