Description
Technical field
The utility model relates to family expenses engineering instrument field, is specially a kind of folding stair.
Background technology
Because the common volume of stair is bigger, average family often can not be equipped with stair, thereby in the substitute that tends to seek stair on the needs during to higher spatial, inconvenience so, and dangerous.
Summary of the invention
The purpose of this utility model is to overcome the defective of existing stair, is convenient to dismounting for average family provides a kind of, is convenient to transport, the less folding stair of volume when taking in.
In order to achieve the above object, the utility model is achieved in that a kind of folding stair, it is characterized in that: it comprises strut rail fixed head, strut rail, junction plate, support bar; The two ends of strut rail fixed head and the two ends of junction plate are equipped with through hole, and the strut rail fixed head is provided with at interval with junction plate and is connected with rivet; Strut rail fixed head and junction plate coupling are located at the two ends of strut rail; Junction plate is provided with groove, support bar is provided with projection, groove on the junction plate and the combination of the coupling of the projection on the support bar; The two ends of support bar are provided with cylindrical protrusions, the through hole interference fit at described cylindrical protrusions and strut rail fixed head two ends.
In order further to improve practicality of the present utility model, support bar is split as 2～5 sections, is threaded between each section.
The utility model adopts above-mentioned design, can break the component as smaller size smaller when not using, thereby conveniently transport and store, and provides convenience for average family uses stair.
