Description
Technical field
A kind of novel anti-side of the utility model is fallen emergency staircase, relates to a kind of anti-side and falls ladder, belongs to the daily necessities field, and particularly a kind of scalable left and right sides support angle prevents that fall down both sides to the left and right, and can place the ladder of thing at the top.
Background technology
Ladder is the very general instrument of ascending a height in daily life or the work; Normally used ladder is trapezoidal single ladder or the ladder that has support bar; Fork before and after one side that these ladders lean against on the supporter in use or support bar and people climb to a higher point, this make when the user stand when higher owing to the crank ladder easily to the left and right both sides fall down, though some ladders have been done improvement at the foot of ladder place; But this has just done improvement on foot of ladder anti-skidding; The problem that still unresolved side is fallen, and the many ladders that use now all not have to be provided with the equipment of putting thing on top just makes support bar scalable or just make cleat stanchion scalable and show with ladder; Can not make the equal telescopic ladder of support bar and cleat stanchion, and the many ladders that use now all there is not to be provided with the equipment of putting thing on top.
Summary of the invention
In order to address the above problem, a kind of novel anti-side of the utility model is fallen emergency staircase a kind of scalable left and right sides support angle is provided, and prevents that fall down both sides to the left and right, and can place the ladder of thing at the top.
A kind of novel anti-side of the utility model is fallen emergency staircase and is achieved in that a kind of novel anti-side of the utility model falls emergency staircase and be made up of glove plate, terraced body, support bar, connecting rod four parts, and a face down bonding of glove plate is connected to two support columns, and the plate face has two holes rotating shaft is housed respectively; The ladder body is made up of first order cleat stanchion, second level cleat stanchion, ball bearing three parts, and the inboard of first order cleat stanchion has groove, and the back side has jack; Second level cleat stanchion is inserted in the groove of first order cleat stanchion, first order cleat stanchion both sides are welded with shackle, and top front face respectively is equipped with two screens screws; Two ball bearings of top welding of second level cleat stanchion, the back side has jack, the upper end welding drum; Cylindrical sleeve is in the rotating shaft of glove plate, and support bar has two, is made up of second level support bar, first order support bar two parts for every; The upper end of second level support bar is welded with spherical shell, and with the ball bearing cover inside, first order support bar is that hollow round bar overlaps second level support bar inside; The screens screw is housed on the first order support bar, and the side is welded with shackle, and connecting rod is the round bar that has hook; Hook is hooked on the shackle, connects terraced body and two support bars, four foot of ladders all overlap rubber sleeve.
During use; At first support bar and terraced body are adjusted to Len req, and fix, then ladder is erected with the screens screw; With two support bars adjusting angle all around as required; The change connecting rod is hooked in the position adjustments angle of terraced body and two support bar shackles and terraced body and two support bars is fixed up, and the support bar with the glove plate is inserted in the suitable jack in the terraced body back side at last, makes the glove plate level.
Beneficial effect
One, the stability of ladder is greatly improved.
Two, simple in structure, easy to use.
Three, with low cost, be easy to promote.
