Abstract

The invention provides a manual lifting type trestle ladder for mounting air conditioners, ceiling lamps and other electric appliances. The manual lifting type trestle ladder comprises a trestle ladder main body, a lifting device and a hoisting device, wherein both the lifting device and the hoisting device are mounted on the trestle ladder main body; items to be supplied are placed on the hoisting device; the lifting device is used for tracking the hoisting device to move upwards in the direction perpendicular to the ground; the hoisting device comprises a sliding mechanism, a hand rocker mechanism II, a hoisting mechanism and a support plate; the sliding mechanism is matched with a sliding track which is arranged on the trestle ladder main body in sliding guide fit manner; both the handrocker mechanism II and the lifting mechanism are arranged between the sliding mechanism and the support plate; the hand rocker mechanism II is used for providing hoisting force for the hoisting mechanism; the support plate is horizontally connected to the hoisting mechanism; the items are placed on the support plate; the hoisting mechanism is used for tracking the support plate to move upwards inthe direction perpendicular to the ground and enable the support plate to be at an appropriate height under the action of the hoisting force.

Description

technical field [0001] The invention relates to the field of ladders, in particular to a miter ladder used for decoration and climbing operations during decoration. Background technique [0002] Diagonal ladder is a kind of ladder. It is necessary to use ladders in decoration, lamp maintenance, daily cleaning and other occasions to facilitate climbing. During the use of existing ladders, operators need to repeatedly move tools up and down, which is time-consuming and laborious. , and in the case of single-person operation, for large or heavy objects, the operator needs to be responsible for climbing the ladder. The construction method is relatively dangerous, and it is prone to the danger of dumping, which will not only damage property, but also endanger personal safety. Contents of the invention [0003] In order to solve the deficiencies of the prior art, the object of the present invention is to provide a kind of ladder used for decoration and climbing work during decor...
