in the figure: 1. the base, 2, support column, 21, through-hole, 3, lift seat, 31, first locating lever, 32, second locating lever, 33, stopper, 4, first railing, 41, rectangular groove, 42, limiting plate, 43, run through the groove, 5, second railing.
Detailed Description
The invention will be further explained with reference to the drawings.
As shown in fig. 1 and 3, the height and width limiting handrail for a road comprises a supporting column 2, a lifting seat 3 and a handrail assembly;
the supporting column 2 is vertically arranged on the base 1, and the lifting seat 3 is vertically arranged on the supporting column 2 in a sliding manner and is locked and fixed through a locking device;
the right end of the lifting seat 3 is provided with a second positioning rod 32, and the upper end of the lifting seat is provided with a limiting block 33 positioned on the left side of the second positioning rod 32;
the rail assembly comprises a first rail 4 and a second rail 5; the first handrail 4 is provided with a through groove 43 with an opening at the right end and penetrating up and down, the through groove 43 is arranged along the length direction of the first handrail 4, the lower side of the right end of the first handrail 4 is provided with a limit plate 42, the right end is rotatably provided with a second handrail 5, and the length of the second handrail 5 is smaller than that of the through groove 43;
the first handrail 4 is provided with a strip-shaped groove 41 which penetrates through the front and the back and is arranged on the left and the right,
the second positioning rod 32 is arranged in the strip-shaped groove 41 in a sliding manner;
furthermore, a plurality of through holes 21 uniformly distributed up and down are formed in the supporting column 2, the lifting seat 3 is sleeved on the supporting column 2, the locking device is a first positioning rod 31, and the first positioning rod 31 is disassembled and assembled in the through holes 21;
further, the first handrail 4 and the second handrail 5 are made of aluminum materials; the lighter material thus makes the railing assembly overall lighter, easy to rotate and retract.
