More-convenient and more-comfortable ladder used in construction work

Abstract

The invention provides a more-convenient and more-comfortable ladder used in construction work, the ladder comprises a telescopic column, a limit bolt, a support base and a return spring; the upper side of a bottom side limit crossbar is welded with the telescopic column; the telescopic column is embedded in the inner side of a longitudinal fixing column; the outer wall of the lower end of the longitudinal fixing column is provided with the limit bolt, and the telescopic column is fixed to the inner side of the longitudinal fixing column by the limit bolt; the longitudinal fixing column passesthrough an upper lateral limiting crossbar and is fixedly connected with a supporting column, and the longitudinal fixing column is welded to a through hole of the upper lateral limiting crossbar; and the front end bolt of an adjusting supporting column is fixedly provided with a pipe groove inner part of the supporting column of the support base. The construction work can be used with a more convenient and comfortable ladder. The telescopic column is embedded in the inner side of the longitudinal fixing column through the return spring, and the telescopic column can be clamped on a foot barof the ladder by elastic stretching during mounting, and can be applied to ladders with foot bars with different widths.

Description

technical field [0001] The invention relates to the technical field of auxiliary devices for decoration ladders, in particular to a more convenient and comfortable ladder for construction work. Background technique [0002] Ladders are an indispensable tool for people to climb up in life and work. Generally, interior decoration requires many aspects of work, walls, floors and ceilings need to be painted, etc. Some places need to use straight ladders, and some need herringbone Ladders, these ladders are only for simple climbing operations, and cannot place tools and improve the working comfort of users. [0003] After patent retrieval, the existing patent No. 201711135449.9 provides a comfortable climbing ladder for building interior decoration, which is convenient for placing materials. It belongs to the field of construction and includes a support plate; the support plate is in a horizontal position and the left side of the end surface of the support plate passes through T...

Problems solved by technology

[0007] The purpose of the present invention is to provide a ladder that can be used more conveniently and comfortably for construction operations, so as to solve the problem that the existing ladders for decoration proposed in the above background technology are all equipped with auxiliary devices, which cannot effectively change the use of existing ladders. way, so that the use of the ladder is more comfortable and the use effect is better; the upper end of the existing straight ladder structure directly leans against the wall when in use, and it is extremely inconvenient for the staff to stand when they climb to the top, which is easy to waste the use of the ladder Height, and when it is directly supported on the wall, and the stability strength is low, it is easy to cause the risk of sliding and increase the risk factor of the staff, and there is no tool placement table on the upper end, so the tools used cannot be placed on the upper end, so Just increased the amount of labor and time produced when changing the tool, further reducing the work efficiency, and holding too many tools in the hand, it is easy to cause the danger of the tool falling; when the ladder is used, people can only benefit from the oblique Or riding on the upper side, the comfort is poor and the work efficiency is low
