Description

Folding ladder

Technical field

The utility model belongs to field of mechanical technique, and in particular to a kind of folding ladder.

Background technology

Common step ladder in existing ladder, especially warehouse, uses integrally formed structure, so that it is not Can storage, in this way when not needing step ladder, due to cannot being stored it, cause to take up a large area, easy-to-collection is not asked Topic.

Invention content

The purpose of this utility model is the presence of the above problem in view of the prior art, it is proposed that a kind of simple in structure, practical The strong folding ladder of property.

The purpose of this utility model can be realized by following technical proposal：A kind of folding ladder, which is characterized in that including ladder Body and support leg, support leg are articulated and connected by connecting shaft and terraced body, and terraced body has multiple steps and is equipped on step surface Non-slip mat, end back face has two symmetrically arranged support bases with ladder, through-hole is offered on support base, in support leg upper end Portion, which is excavated, U-shaped notch, is equipped with two symmetrically arranged connecting seats in U-shaped indentation, there, extends outwardly simultaneously on connecting seat lateral wall The hook of through hole can be snapped in by being formed with, and be additionally provided with thrust plate in U-shaped indentation, there and thrust plate is between two connecting seats, and two A positioning column is all had on connecting seat madial wall and positioning column can be resisted against on thrust plate side wall when pulling outward.

In above-mentioned folding ladder, there is Anti-skid sheet on terraced body lower face.

In above-mentioned folding ladder, non-slipping block is equipped on support leg lower face.

Compared with prior art, the utility model by terraced body be arranged support base, connecting seat is set in support leg, When this ladder is opened, rotational support foot is until the hook on connecting seat is directed at the through-hole on support base, so that support leg It firm can link together with terraced body, stability is good；Simultaneously in order to ensure that hook can consolidate snaps onto through hole, connect two It is provided with thrust plate between joint chair, in this way when hook is inserted in through-hole, then pulls two connecting seats outward so that positioning column energy Be resisted against on thrust plate side wall, in this way by thrust plate by connecting seat low pressure tightly on support base, prevent hook from through hole It detaches, it is safe；The non-slip mat that is arranged on step surface plays the role of anti-skidding simultaneously, accordingly even when in wet environment Under, people stand will not occur when on step surface due to foot is sliding and the case where drop from ladder.

Specific implementation mode

It is specific embodiment of the utility model and in conjunction with attached drawing below, the technical solution of the utility model is made further Description, but the utility model is not limited to these examples.

As shown in Figures 1 to 4, this folding ladder includes terraced body 1 and support leg 2, and support leg 2 is cut with scissors by connecting shaft 5 and terraced body 1 It connects in succession, terraced body 1 has multiple steps 11 and is equipped with non-slip mat 12 on 11 face of step, has at the 1 upper end back side of terraced body Two symmetrically arranged support bases 13 offer through-hole 14 on support base 13, and being excavated in 2 upper end of support leg has U-shaped notch, in U Type indentation, there be equipped with two symmetrically arranged connecting seats 21, extend outwardly on 21 lateral wall of connecting seat and be formed with can be snapped in it is logical Hook 22 at hole 14 is additionally provided with thrust plate 23 in U-shaped indentation, there and thrust plate 23 is between two connecting seats 21, two connecting seats A positioning column 24 is all had on 21 madial walls, the width for being smaller than thrust plate 23 between two positioning columns 24 and ought be pulled outward When positioning column 24 can be resisted against on 23 side wall of thrust plate.

By the way that support base 13 is arranged in terraced body 1, connecting seat 21 is set in support leg 2, when opening this ladder, is rotated Support leg 2 until connecting seat 21 on hook 22 be aligned support base 13 on through-hole 14 so that support leg 2 can consolidate with Terraced body 1 links together, and stability is good.

Simultaneously in order to ensure that hook 22 can consolidate snaps onto at through-hole 14, thrust plate is provided between two connecting seats 21 23, in this way when hook 22 is inserted in through-hole 14, then two connecting seats 21 are pulled outward so that positioning column 24 can be resisted against thrust On 23 side wall of plate, in this way by thrust plate 23 by the low pressure tightly of connecting seat 21 on support base 13, prevent hook 22 from through-hole 14 Place detaches, safe.

The non-slip mat 12 that is arranged on 11 face of step plays the role of anti-skidding simultaneously, accordingly even when in wet condition, people Standing will not occur when on 11 face of step due to foot is sliding and the case where drop from ladder.

Further, there is Anti-skid sheet 3 on 1 lower face of terraced body, non-slipping block 4 is equipped on 2 lower face of support leg.Pass through Anti-skid sheet 3 and non-slipping block 4 are contacted with ground, enhance the frictional force between ladder and ground, to improve the stability of this ladder, Be not in the case where causing people to fall down since ladder is mobile when people stand on ladder in this way.

The specific embodiments described herein are merely examples of the spirit of the present invention.The utility model institute Belonging to those skilled in the art can make various modifications or additions to the described embodiments or using similar Mode substitute, but without departing from the spirit of the present application or beyond the scope of the appended claims.
