Ladder with adjustable telescopic height
The invention discloses a ladder with adjustable telescopic height and relates to the technical field of ladder tools for climbing. The ladder with the adjustable telescopic height comprises six ladder columns, wherein fixed cross rods are fixedly installed at upper ends of the ladder columns, the diameters of the ladder columns are gradually reduced from bottom to top, the upper ladder columns and the lower ladder columns are connected in a sleeved mode, cleaning mechanisms are fixedly installed at upper ends of the ladder columns, and locking mechanisms are fixedly installed on inner sides of lower ends of the ladder columns; a knob is rotationally mounted at a lower end of a front surface of the ladder column, and the cleaning mechanism comprises an air inlet groove, a fixed block, a movable plug and a cleaning part. According to the ladder with the adjustable telescopic height, the cleaning mechanism and the locking mechanism are arranged, the two ladder columns which are connected in a sleeved mode are automatically locked when the ladder columns are stretched, the locking step when the ladder stretches out and draws back is simplified, and when the ladder columns contract, dust and soil blocks remaining at the sleeved connection position of the ladder columns are removed through the cleaning mechanism; dust and soil blocks are prevented from being driven to enter the sleeved ladder columns when the ladder is contracted, so the contraction function of the ladder is not influenced.
本发明公开了一种可调节伸缩高度的梯子，涉及登高用工具梯子技术领域。该可调节伸缩高度的梯子，包括梯柱，所述梯柱的上端固定安装有固定横杆，梯柱为六节，且由下至上梯柱的直径逐渐变小，上下梯柱相互套接，所述梯柱的上端固定安装有清理机构，所述梯柱的下端内侧固定安装有锁定机构，所述梯柱的正面下端转动安装有旋钮，清理机构包括进气槽、固定块、活动塞和清理件。该可调节伸缩高度的梯子，设置清理机构和锁定机构，在梯柱拉伸时自动将套接的两梯柱锁定，简化了梯子伸缩时的锁定步骤，在梯柱收缩时，通过清理机构将残留在梯柱套接处的灰尘土块清除，避免了梯子在收缩时带动灰尘土块进入套接的梯柱内，影响梯子的收缩功能。
