Abstract
The invention provides a stable aluminum alloy herringbone ladder, which comprises a pedal, a first support column, a second support column, a third support column and a fourth support column, wherein the pedal is a rectangular plate, two adjacent corners of the pedal are respectively connected with the third support column and the fourth support column through shafts, and the other two corners of the pedal are respectively connected with the first support column and the second support column through sliding rails in a sliding manner, so that the stable aluminum alloy herringbone ladder has the beneficial effects that: this device is stepped on by foot and is stood more stably, and the security performance of this device is higher.
Description
Technical Field
The invention relates to the technical field of aluminum profiles, in particular to a stable aluminum alloy herringbone ladder.
Background
The existing herringbone ladder is not stable enough, and the feet of a person step on the ladder to generate sloshing feeling. It is therefore desirable to provide a herring ladder with improved tread stability.
Disclosure of Invention
The invention provides a stable aluminum alloy herringbone ladder, which is designed and developed to achieve the purpose that the device is more stable when being stepped on and stands by feet, and the device is higher in safety performance.
The invention provides the following technical scheme: the steady aluminum alloy herringbone ladder comprises a pedal 1, a first support column 2, a second support column 3, a third support column 4 and a fourth support column 5, wherein the pedal 1 is a rectangular plate, two adjacent corners of the pedal 1 are respectively connected with the third support column 4 and the fourth support column 5 through shafts, the other two corners of the pedal 1 are respectively connected with the first support column 2 and the second support column 3 through sliding rails 6 in a sliding mode, the first support column 2 is movably connected with the upper end of the third support column 4, and the second support column 3 is movably connected with the upper end of the fourth support column 5.
The double ladder further comprises a hanging rod 7, one end of the hanging rod 7 is movably connected with the third support column 4, and the other end of the hanging rod 7 is hung on the first support column 2.
The double ladder further comprises a step 8, wherein the step 8 is fixedly arranged between the first support column 2 and the second support column 3, and the step 8 is also fixedly arranged between the third support column 4 and the fourth support column 5.
The herringbone ladder further comprises an armrest 9, the armrest 9 is in a U-shaped body, and two ends of the armrest 9 are fixedly connected with the first support column 2 and the second support column 3 respectively.
The invention has the beneficial effects that: the pedal 1 is a rectangular plate, the pedal 1 is a rectangular flat plate, two adjacent corners of the pedal 1 are respectively connected with the third support column 4 and the fourth support column 5 through shafts, and the two adjacent corners of the pedal 1 are fixedly connected with the shafts. The third support column 4 and the fourth support column 5 are provided with shaft holes, and shafts are inserted into the shaft holes to be connected. The rest two corners of the pedal 1 are respectively connected with the first support column 2 and the second support column 3 in a sliding manner through slide rails 6. When the herringbone ladder is unfolded, two feet of the pedal 1 slide horizontally along the sliding rails 6, as shown in the figure, the stability is greatly enhanced when a person climbs and tramples on the pedal 1, the foot of the herringbone ladder is more stable in treading and standing, and the safety performance of the herringbone ladder is higher.
