Detailed description of the invention
As Figure 1-5, the utility model discloses a kind of double ladder, comprise: left socle 1, left limit block 2, left brace 3, left bearing bar 4, right support 5, right limit block 6, right brace 7, right bearing bar 8, gangbar 9, foot rest 10, the right side vertically multiple left limit block 2 of uniform welding of described left socle 1, the upper end of described left limit block 2 has helical teeth, described left socle 1 vertically evenly installs multiple left brace 3 by bolt, and the quantity of left brace 3 is identical with the quantity of left limit block 2, the lower end of described left brace 3 is connected with the left end of left bearing bar 4 by the mode of welding, the left part lower end of described left bearing bar 4 has helical teeth, and the helical teeth of left bearing bar 4 lower end engages with the helical teeth of left limit block 2 upper end, the left side vertically multiple right limit block 6 of uniform welding of described right support 5, the upper end of described right limit block 6 has helical teeth, described right support 5 vertically evenly installs multiple right brace 7 by bolt, and the quantity of right brace 7 is identical with the quantity of right limit block 6, the lower end of described right brace 7 is connected with the right-hand member of right bearing bar 8 by the mode of welding, the right part lower end of described right bearing bar 8 has helical teeth, and the helical teeth of right bearing bar 8 lower end engages with the helical teeth of right limit block 6 upper end, the cross section of described right bearing bar 8 is fluted body, and left bearing bar 4 is stuck in right bearing bar 8, described right bearing bar 8 is connected with left bearing bar 4 by bolt, the upper end of described right brace 7 is connected with gangbar 9 by bolt, a foot rest 10 is installed by hinge in the lower end of described gangbar 9, the two half-unit of double ladder described in the utility model is symmetrical and structure is identical, the left bearing bar 4 of described the top is connected by the left bearing bar 4 of hinge with second half the top of double ladder described in the utility model, the right bearing bar 8 of described the top is connected by the right bearing bar 8 of hinge with second half the top of double ladder described in the utility model.
The utility model implements like this: when the two half-unit of double ladder described in the utility model is opened, left bearing bar 4 held by left brace 3, in order to prevent left bearing bar 4 downward-sloping, the helical teeth of left bearing bar 4 lower end engages with the helical teeth of left limit block 2 upper end, such left limit block 2 has not only shared the part pulling force of left brace 3, in order to support left bearing bar 4, also can prevent left socle 1 from offseting relative to left bearing bar 4 simultaneously, the angle between left socle 1 and left bearing bar 4 is made not to be 90 degree, same principle, right bearing bar 8 held by right brace 7, right limit block 6 also plays the effect of support, in addition, because right bearing bar 8 is connected with left bearing bar 4 by bolt, and left bearing bar 4 is stuck in right bearing bar 8, after such formation entirety, people just steadily can step down in left bearing bar 4 with on right bearing bar 8, when needs are packed up, first former and later two half portion of double ladder described in the utility model are closed real, because two half-unit structure is identical, like this, only pin need be stepped down in simultaneously on two foot rests 10, foot rest 10 drives gangbar 9 to move down, foot rest 10 down through the right bearing bar 8 of right brace 7 pull-up, the left end of right bearing bar 8 is then inclined upwardly and drives the right-hand member of left bearing bar 4 to be inclined upwardly, until left bearing bar 4 sticks in right bearing bar 8 completely, namely right bearing bar 8 and left bearing bar 4 are completely vertically, finally foot rest 10 is packed up, double ladder described in the utility model like this two half-unit close actual arrival together after, once amount to again from centre respectively again, volume reduces further, thus very large decrease taking space, easy to use.
Last it is noted that above embodiment only in order to illustrate the utility model and and technical scheme described by unrestricted the utility model; Therefore, although this manual has been described in detail the utility model with reference to each above-mentioned embodiment, those of ordinary skill in the art should be appreciated that and still can modify to the utility model or equivalent replacement; And all do not depart from technical scheme and the improvement thereof of spirit and scope of the present utility model, it all should be encompassed in right of the present utility model.
