Drawings
FIG. 1 is a schematic front view of the present invention;
in the figure, 1, a second cross rod, 2, an adjusting hand wheel, 3, an adjusting shaft, 4, a first bevel gear, 5, a second bevel gear, 6, an adjusting screw rod, 7, a sliding groove, 8, a nut sleeve, 9, a first cross rod, 10, a plug, 11, an inserting hole, 12, an L-shaped screw rod, 13, a jacking screw sleeve, 14, an arc-shaped opening and 15, a sliding block are arranged.
Detailed Description
A scaffold cross bar convenient for adjustment and installation comprises a first cross bar 9 in a circular tube shape, a second cross bar 1 and an adjusting device, wherein plugs 10 are fixedly arranged at the outer end parts of the first cross bar and the second cross bar, the inner end part of the first cross bar is inserted into the second cross bar, the second cross bar is provided with a mounting hole, the adjusting device comprises an adjusting hand wheel 2, an adjusting shaft 3 and an adjusting screw 6, one end of the adjusting shaft extends into the second cross bar from the mounting hole, a first bevel gear 4 is sleeved on the adjusting shaft, the adjusting hand wheel is fixedly arranged at the outer end part of the adjusting shaft, a second bevel gear 5 meshed with the first bevel gear is sleeved at the end part of the adjusting screw rod, and the adjusting screw is provided with a nut sleeve 8, the inner end part of the first cross rod is fixedly connected with the nut sleeve, the inner wall of the second cross rod is fixedly provided with a sliding groove 7, and a sliding block 15 fixedly connected with the nut sleeve is clamped in the sliding groove.
Optimally, the plug is of a wedge-shaped structure, and the lower part of the plug is provided with the jack 11, so that the cross rod and the vertical rod are conveniently connected.
Further, the outer end portion fixed mounting of first horizontal pole and second horizontal pole has L shape screw rod 12, install the tight swivel nut 13 in top on the L shape screw rod, not only through being connected of plug and disc between horizontal pole and the montant, it is tight through the tight swivel nut top in top moreover, makes the structure of horizontal pole more firm.
