Abstract

The invention provides a ladder foot with a retractable supporting structure of a ladder. The ladder foot is characterized in that the supporting structure comprises two supporting rod parts, two adjusting connecting rods and an adjusting positioning seat, wherein the upper ends of the two supporting rod parts are hinged to outer sides of two ladder feet and the lower ends of the two adjusting connecting rods are hinged to the lower ends of the two supporting rod parts respectively; the adjusting positioning seat is fixedly arranged between the two ladder feet; an adjusting positioning groove is formed in each of the left and right sides of the adjusting positioning seat and the adjusting connecting rods can slide and be positioned in the adjusting positioning grooves; each adjusting positioning groove comprises a long groove hole and round holes in the two ends of the long groove hole; the upper end of each adjusting connecting rod is in sliding connection with the corresponding adjusting positioning groove through an elastic positioning part, and the elastic positioning part comprises a rod body; a stair-shaped positioning head with three grades and a spring sleeve the rod body; a front-grade stair of the stair-shaped positioning head correspondingly abuts against the corresponding adjusting connecting rod, and the diameter of the front-grade stair is smaller than or equal to the groove width of the long groove hole; the diameter of a middle-grade stair is greater than the groove width of the long groove hole and is smaller than or equal to the diameter of a round hole; the diameter of a rear-grade stair is greater than the diameter of the round hole. The ladder foot provided by the invention has high supporting stability with the ground, is convenient to unlock and is convenient to store.

Description

technical field [0001] The invention relates to a ladder, in particular to a ladder foot, which has a retractable support structure. Background technique [0002] Ladders are commonly used climbing tools, such as straight ladders, herringbone ladders, and hanging ladders. In most cases, ladders can meet the needs of users, but in some cases, such as places with high heights, or places where users need to move frequently, the bottom of conventional ladders may not be supported by the ground. A stable situation poses a safety hazard. [0003] Therefore, how to solve the above-mentioned problems becomes the subject to be researched and solved by the present invention. Contents of the invention [0004] The object of the present invention is to provide a ladder foot with a telescopic support structure to solve the problem of unstable support between the bottom and the ground in the prior art. [0005] In order to achieve the above object, the technical solution adopted by t...
