Detailed Description

The following describes embodiments of the present invention with reference to the drawings.

As shown in figures 1-2, the utility model discloses a ladder body that the symmetry set up, the top of both sides ladder body extends formation connecting portion to the opposite side respectively, runs through the connecting portion of ladder body around the articulated elements 4, makes the top transposition of both sides ladder body.

As shown in FIGS. 3 to 4, the concrete structure of the single-side ladder body is as follows: comprises ladder frames 12 which are symmetrically arranged in parallel, the ladder frames 12 are in a columnar structure, a plurality of steps 16 are vertically and uniformly distributed between the ladder frames 12, the steps 16 are also in a columnar structure, a plurality of mounting holes are arranged on the ladder frames 12 corresponding to the steps 16, a group of limiting blocks 15 which are arranged up and down are fixedly connected along the outer edges of the mounting holes, two ends of each step 16 respectively penetrate through gaps between the limiting blocks 15, the ladder comprises ladder frames 12 and guard plates 11, wherein the ladder frames 12 are internally provided with a plurality of base rods 7 at intervals, the tail ends of the base rods 7 are hinged with the ladder frames 12, the upper part and the lower part of the outer side of each ladder frame 12 are respectively fixed with a connecting block 8, a connecting shaft 9 is arranged between the connecting blocks 8, two ends of the connecting shaft 9 are respectively rotatably positioned in the adjacent connecting blocks 8, each guard plate 11 is of a strip structure, and the guard plates 11 are rotatably positioned on the ladder frames 12 through the connecting shafts 9.

Lie in on the body of the ladder of both sides and between the relative base rod 7 that sets up, connect through a plurality of successive layers nested telescopic link 6, the equal leanin rigid coupling guardrail 3 in top of the ladder body of both sides, the top of the ladder body of one side still with 3 parallel rigid coupling stands 1 of guardrail, the articulated handle 2 in middle part of stand 1, after the ladder body opens certain angle around articulated elements 4 to both sides, stand 1 and guardrail 3 are personally submitted perpendicularly with the level.

And a protective edge covering 10 is attached along the outer edge of each protective plate 11, and the protective edge covering 10 is of a rubber structure. The ladder frame 12 is of a square steel structure and the ladder 16 is of a cylindrical structure. The upper part of the surface of the step 16 is covered with a non-slip mat 17, and the non-slip mat 17 is of a rough-surface rubber structure. Each ladder frame 12 is provided with four base rods 7, each base rod 7 is of a hollow cylindrical structure, and fastening screws 5 are vertically arranged at the openings of the two base rods 7 above the base rods 7. The bottom end of each ladder frame 12 is sleeved with a bottom cushion 14.

The utility model discloses a concrete working process as follows:

the utility model discloses can make both sides ladder body freely open and shut through the effect of articulated elements 4, when the staircase was opened, telescopic link 6 between the base rod 7 was elongated, after tensile to predetermined position, rotatory fastening screw 5 made telescopic link 6 fixed, articulated between base rod 7 and the ladder frame 12, made base rod 7 remain the level all the time. In this embodiment, the single ladder frame 12 has four base rods 7, and the number of the telescopic rod sections for connecting the ladder bodies on the two sides is one section, three sections and five sections from top to bottom in sequence. After the angle adjustment of the ladder body is finished, the guard plate 11 can be rotated by the connecting block 8 and the connecting shaft 9.
