Provided is a ladder with adjustable beam spacing. Axial slide grooves are formed in a first supporting stand column and a second supporting stand column of the ladder, two groove walls of the slide grooves are provided with multiple sets of through holes opposite in pairs, clamping nails are arranged in the through holes, one end of a telescopic rod is connected to a first beam connecting block through a first rotating pair, the first beam connecting block is connected to a first slide block through a second rotating pair, the first slide block is embedded in the slide groove of the first supporting stand column, the other end of the telescopic rod is connected to a second beam connecting block through a third rotating pair, the second beam connecting block is connected to a second slide block through a fourth rotating pair, the second slide block is embedded in the slide groove of the second supporting stand column, and the shapes and sizes of the first slide block and the second slide block are closely matched with those of the slide grooves. According to the ladder, the number of beams can be adjusted according to demands, the width of the space between the stand columns on the two sides is adjusted, the width of the space between the beams is adjusted, the angle between footboards and the ground is adjusted, and the occupied space of the ladder can be narrowed through folding.
Description
technical field [0001] The invention relates to a tool, in particular to a ladder with an adjustable beam distance. Background technique [0002] Ladders are commonly used to provide further access to locations that are otherwise inaccessible to their users. Ladders exist in many shapes and sizes, such as straight ladders, straight extension ladders, stepladders, and combined stepladders and extension ladders. So-called modular ladders include many of the benefits of other ladder designs in a single ladder. [0003] Ladders are a common tool used by professional craftsmen and homeowners alike. When it comes to standing on a ladder to perform a particular task, sometimes the use of a ladder can be an awkward experience even for those who use it regularly. For example, it's easy to lose your balance on a ladder when doing overhead projects (eg, painting the ceiling, changing a light bulb, etc.). Also, when working on a ladder requires access to tools or other sources (eg, ...
