Problems solved by technology

The "person" character ladder does not need to lean against the wall, and the ladder itself can stand on the ground; but the "person" character ladder should not be too high, otherwise it is easy to roll over. It needs to occupy a large, relatively horizontal ground area. If the corresponding ground non-horizontal surface (such as a step structure) or the relatively horizontal ground position is not large enough, the "herringbone" ladder is not suitable; in addition, ordinary The word "one" or "person" ladder cannot be disassembled, which will cause inconvenience in transportation
Another tool is scaffolding. Although the scaffolding can be built very high, the scaffolding is very heavy and it is not suitable to be used on the ground of the stepped structure.

Embodiment Construction

[0025] An upright ladder, see figure 1 As shown, it includes the bottom frame A, the adjustment frame B, the extension frame C, the top frame D, and the extension tube E.

[0026] The chassis A, see figure 2 As shown, it includes left and right two support tubes 1 and three crossbars 2; the lower ends of the left and right support tubes are provided with metal plates 3, and a rubber plate 4 is pasted on the bottom of the metal plates. Or rubber plate, all adopts circle, and the diameter of metal plate is 30cm, and the diameter of rubber plate is 31cm; The upper end of left and right support pipe is all provided with internal thread interface 5, adopts left-handed thread structure, and the length of thread is 20cm.

[0027] The adjustment frame B, see image 3 As shown, it includes two left and right support pipes 1 and a cross bar 2; the upper ends of the left and right support pipes of the adjustment frame are provided with plugs 6, and the lower ends are provided with int...

Abstract

The invention provides an upright ladder. The upright ladder comprises assemblies including a bottom frame, an adjusting frame, a lengthening frame, a top frame and lengthening tubes. The bottom frame and the top frame are respectively provided with metal plates and rubber plates. The adjusting frame is provided with threaded rods used for adjusting the length of the ladder. The lengthening frame and the lengthening tubes are respectively provided with an insertion hole and an insertion head. The assemblies are connected into the ladder through threaded connectors or the insertion holes and the insertion heads. The height of the ladder is adjusted through the threaded rods of the adjusting frame so that the ladder tightly abuts against the ground and a ceiling. The upright ladder has the advantages of being firm, small in occupied space, detachable, convenient to transport and overcoming some functional defects of linear ladders or A-shaped ladders.

Description

technical field [0001] The present invention relates to a ladder. Background technique [0002] As we all know, there are basically two types of commonly used ladders, one is the "one" character ladder, and the other is the "person" character ladder. The "one" character ladder is leaning against the wall; when working at a place a little farther away from the wall (for example: the middle position of the ceiling), there is nothing you can do. The "person" character ladder does not need to lean against the wall, and the ladder itself can stand on the ground; but the "person" character ladder should not be too high, otherwise it is easy to roll over. It needs to occupy a large, relatively horizontal ground area. If the corresponding ground non-horizontal surface (such as step structure) or the relatively horizontal ground position is not large enough, the "herringbone" ladder is not suitable; in addition, ordinary The "一" character ladder or "person" character ladder cannot ...
