The invention discloses an intelligent ladder capable of being adjusted to ascend and descend. Movable plates are connected to the two sides of an inner frame of a frame body in a sliding mode, connecting rods are hinged to one sides of the movable plates, one ends, away from the movable plates, of the connecting rods are hinged to one sides of first sliding blocks, fastening bolts are in threadedconnection with the upper portions of supporting plates, racks are fixed to the two sides of the frame body correspondingly, and pawls matched with the racks are hinged to the two sides of the platebodies correspondingly. According to the aluminum ladder, the frame body is pulled upwards, so that the frame body moves upwards, the racks are driven to move upwards when the frame body moves upwards, the pawls are clamped into tooth grooves of the corresponding racks all the time through the pulling force of a tension spring, and the frame body can only move upwards and cannot move downwards; when the positions of pedals need to be adjusted up and down, the fastening bolts are rotated, so that the fastening bolts drive the movable plates to move, the movable plates drive the first sliding blocks to slide in the first sliding grooves through the connecting rods, the first sliding grooves drive the pedals to move, adjustment can be conducted when the positions of the pedals are not good, and the intelligent ladder capable of being adjusted to ascend and descend is convenient for a user to use.
本发明公开了一种智能可调升降梯子，框体的内框两侧均滑动连接有活动板，活动板的一侧铰接有连杆，连杆远离活动板的一端铰接于第一滑块的一侧，支撑板的上部螺纹连接有紧固螺栓，框体的两侧均固定有齿条，板体的两侧均铰接有与齿条相匹配的棘爪。该铝梯通过向上拉拽框体，使得框体上移，框体上移时带动齿条上移，由拉簧的拉拽力将棘爪时刻卡入相应的齿条的齿槽内，使得框体只能向上移动无法向下移动；在需要上下调整踏板位置时，旋转紧固螺栓，使得紧固螺栓带动活动板移动，活动板通过连杆带动第一滑块在第一滑槽内滑动，第一滑槽带动踏板进行移动，从而可以在踏板位置不佳时进行调整，方便使用者进行使用。
