A kind of upright ladder, comprising assembly has: underframe, adjusting bracket, lengthening frame, upper frame, extension pipe.Described underframe, adjusting bracket, lengthening frame, upper frame, each assembly all comprises: left and right two stay pipes and cross bar, cross bar is connected between two stay pipes.
Described underframe, the lower end of its left and right stay pipe is also all provided with metal sheet, posts rubber tile again in the below of metal sheet, and the upper end of left and right stay pipe is all provided with internal thread interface;
Described adjusting bracket, also comprises screw rod; The upper end of the left and right stay pipe of adjusting bracket is all provided with plug, and lower end is all provided with internal thread interface; The top and bottom of screw rod are all provided with outside nut interface, and centre is provided with ear; The stay pipe of screw rod upper end and adjusting bracket links together, and lower end is connected with the stay pipe of underframe;
Described lengthening frame, the lower end of its left and right stay pipe is all provided with jack, and upper end is provided with plug;
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, above metal sheet, also post rubber tile.
Further, described extension pipe, lower end is provided with jack, and upper end is provided with plug.
Further, plug recited above is 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 assembly from coming off on ladder, the jack of described upper frame stay pipe, the jack of lengthening 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, in order to improve convenience when to carry out operation on ladder and completeness, 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 selectively and lengthen frame or extension pipe, 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, firmly; Take ground space few; Detachably, convenient transportation; Compensate for " one " word ladder or some defects functionally of " people " word ladder.
