Liftable work ladder with tool box

Abstract

The invention relates to a work ladder with a tool box capable of lifting. The work ladder with the tool box capable of lifting comprises a ladder main body capable of unfolding toward the left side and the right side and folding, and a tool box arranged on the ladder main body. The work ladder with the tool box capable of lifting is characterized in that the tool box is restrained on the top of the ladder main body and can slide up and down, a lifting locking structure is formed between the tool box and the ladder main body, and the tool box can be locked at the height by the lifting locking structure after the fact that the tool box is lifted to the required height. The tool box is used for storing various tools; in addition, the tool box is restrained on the top of the ladder main body and can slide up and down, the lifting locking structure is formed between the tool box and the ladder main body, the tool box can be locked at the suitable height by the lifting locking structure, the tool box is lifted to the suitable height and the maintenance personnel can take the tools conveniently without bending down or squatting for performing the maintenance work while standing on the work ladder, and the use of the work ladder is more humanized.

Description

technical field [0001] The invention relates to a ladder with a tool box, in particular to a working ladder with a liftable tool box. Background technique [0002] Ladders are a common basis for climbing up to get things or maintenance in home life. There are roughly two types of ladders. One is a straight ladder. This ladder includes two poles and a crosspiece between the two poles. It can be used upright. When in use, the ladder needs to be leaned against a high fixed position to provide support for the ladder, and it only provides a single function of climbing. If this kind of ladder is used for maintenance, it is necessary to take and place tools up and down many times. convenient. The other is the ladder, which is mostly composed of the main ladder frame and the supporting ladder frame hinged at the top. Compared with the straight ladder, it can carry out climbing operations in the suspended position, but most ladders do not have it. The function of storing tools also...

Problems solved by technology

However, the aforementioned tool box and the ladder are relatively fixed, and the upper and lower heights of the tool box relative to the ladder cannot be changed. Because the staff has a certain height, when a person stands on the top of the ladder, the hand is at a certain height from the tool box, and the staff needs to bend down or Squat down to pick up and place tools. However, the top of the ladder is generally narrow for people to step on. It is inconvenient and dangerous to bend or squat down.

Although the length of the main ladder frame of some miter ladders is higher than that of the supporting ladder frame, so that the tool box is at a certain height from the uppermost standing platform, it is relatively convenient to take and place tools from the tool box, but due to the high main ladder frame, this kind of After the ladder is folded, it is bulky, and it is inconvenient to place the ladder. In addition, due to the different heights of the staff, the height requirements for the most suitable tool box relative to the standing position of the ladder are also different. The tool box with a fixed height position cannot be most suitable for all staff.
