Detailed Description
The invention will be further described with reference to the accompanying drawings and specific embodiments:
referring to fig. 1 to 4, a portable elbow structure includes a base plate 1, a rotating shaft 101, a stop lever 102 and a driving mechanism 2; further comprising: a mounting hole 103; the mounting hole 103 is arranged at the lower part of the bottom plate 1, and the aperture of the mounting hole 103 is phi 3.25, phi 3.0, phi 2.75 or phi 2.5.
The rotating shaft 101 and the stop lever 102 are connected to the upper part of the bottom plate 1 in a welding manner, when in use, the pipeline 3 to be bent is placed between the rotating shaft 101 and the stop lever 102, and then the driving mechanism 2 is rotated, so that the driving rod 201 of the driving mechanism 2 pushes the pipeline 3 to be bent. The utility model discloses a set up the mounting hole 103 that the aperture is phi 3.25, phi 3.0, phi 2.75 or phi 2.5 in bottom plate 1 lower part, just in time with 4 pipe diameters of scaffold steel pipe the same, peg graft mounting hole 103 during the use on the visible scaffold steel pipe 4 everywhere of job site, can realize quick installation, the utility model discloses saved the base that desk-top bending machine set up for the holding device is stable, used mounting hole 103 to combine PMKD 1 with scaffold steel pipe 4, it is more portable, do not use expensive electromechanical drive mechanism, it is cheaper.
