Abstract
The utility model relates to a herringbone ladder, comprising a first ladder frame (1) and a second ladder frame (1). The herringbone ladder is characterized in that the first ladder frame is movably connected with one end of the second ladder frame, a plurality of pedals (3) are arranged on the first ladder frame and the second ladder frame with equal intervals, the pedals on the two ladder frames are respectively horizontally opposite, every two opposite pedals are connected by a rope (4), and the pedals are welded on the ladder frames. According to the technical scheme, the herringbone ladder has the advantages of stable structure, working convenience, good skid resistance and good working angle controllability.
Description
Technical field
The utility model relates to a kind of double ladder.
Background technology
Mobile ladder in the market has following defective:
1, material is wooden, and structure is insecure, enough becomes potential safety hazard; 2, stepped design is unreasonable, and is inconvenient during use, should not walk; 3, wooden employing iron nail combination, easily come off; Unstablely when 4, between two ladders, the intersection point width is equally walked easily fall; 5, do not have antiskid glue cushion easily to slip; 6, do not have static line, angle can not be controlled.
The utility model content
For the above, the utility model aims to provide a kind of Stability Analysis of Structures, walking is convenient, skid resistance is good, the controlled double ladder of walking angle.
For achieving the above object, a kind of double ladder of the present utility model, comprise the first ladder and the second ladder, one end active link of described the first ladder and the second ladder, on described the first ladder and the second ladder, spacing arranges some pedals equably, pedal on two ladders level respectively is oppositely arranged, and is connected by rope in the middle of two relative pedals, and pedal is welded on ladder.
Maximum subtended angle between described the first ladder and the second ladder is 35 °.
Described the second terraced bar of ladder two is embedded in respectively the inboard of the first ladder two terraced bars.
The end of described the second terraced bar of ladder two and the first ladder two terraced bars is set with footmuff.
Described the first ladder, the second ladder and pedal are made of aluminum.
Adopt the double ladder of this programme, an end active link due to described the first ladder and the second ladder, on described the first ladder and the second ladder, spacing arranges some pedals equably, pedal on two ladders level respectively is oppositely arranged, connected by rope in the middle of two relative pedals, pedal is welded on ladder, and the double ladder of employing present technique has Stability Analysis of Structures, walking is convenient, skid resistance is good, the controlled beneficial effect of walking angle.
Description of drawings.
Fig. 1 is structural representation of the present utility model.
The specific embodiment
As shown in Figure 1, a kind of double ladder of the present utility model, comprise aluminum the first ladder (1) and the second ladder (2), one end of described the first ladder (1) and the second ladder (2) is by screw structural (8) active link, on described the first ladder and the second ladder, spacing arranges some aluminum pedals (3) equably, pedal on two ladders level respectively is oppositely arranged, and pedal is welded on ladder, is connected by rope (4) in the middle of two relative pedals (3).Rope is fixedly connected near on the pedal of upper end, but should guarantee that the maximum subtended angle between described the first ladder (1) and the second ladder (2) is 35 °, convenient walking.Described the second terraced bar of ladder two (5) is embedded in respectively the inboard of the first terraced bar of ladder two (6), Stability Analysis of Structures, the end of described the second terraced bar of ladder two (5) and the first terraced bar of ladder two (6) is set with footmuff (7), footmuff (7) is fixed on terraced bar by blind rivet (9), has skidproof effect, described the first ladder (1), the second ladder (2) and pedal (3) are made of aluminum, and material is light, and walking is convenient.
Above embodiment is described preferred embodiment of the present utility model; be not that scope of the present utility model is limited; under the prerequisite that does not break away from the utility model design spirit; various distortion and improvement that the common engineers and technicians in this area make the technical solution of the utility model all should fall in the definite protection domain of claims of the present utility model.
