Described upper frame, the lower end of its left and right stay pipe is all provided with jack, and the upper end of stay pipe is also provided with metal sheet, also posts rubber tile above metal sheet.
Further, described extension pipe, lower end is provided with jack, and upper end is provided with plug.
Further, plug recited above is to be connected with described jack, and size and the jack of plug match.
Further, the external screw joint of the internal thread interface of the stay pipe upper end of described underframe, the screw rod lower end of adjusting bracket, all adopts left hand thread structure; The internal thread interface of the stay pipe lower end of described adjusting bracket, the external screw joint of screw rod upper end, all adopt right-handed thread structure.
Further, in order to prevent that assembly from coming off on ladder, the jack of described upper frame stay pipe, the jack that lengthens frame stay pipe, the jack of extension pipe, its side is all provided with screw; Corresponding with screw, be provided with screw.
Further, stay pipe recited above and cross bar, adopt metal material.
Further, convenience and completeness while carrying out operation in order to improve on ladder, the upright ladder of described one, is also provided with a safety belt.
The present invention, in use, is connected to adjusting bracket on underframe, then according to the height of ground and furred ceiling, connects and lengthen frame or extension pipe selectively, then connect upper frame; Connect complete after, by rotary screw, regulate height, ladder is withstood between ground and furred ceiling tightly.
Rubber tile in the present invention has anti-skidding and insulating effect.
Beneficial effect of the present invention is mainly manifested in: can vertically stand between furred ceiling and ground, and firm; Take ground space few; Detachably, convenient transportation; Make up the defect in " one " word ladder or some functions of " people " word ladder.
