[0018] Compared with the prior art, the utility model of a multi-form storage ladder for construction has at least the following

[0019] Beneficial effects:

[0020] 1. The multi-form storage ladder for construction workers is a multifunctional ladder that can be converted into a herringbone ladder and a straight ladder. When used as a straight ladder, the first ladder body and the connecting structure are sleeved and fixed by the second fixing structure. The second ladder body is hinged with the connecting structure to be stretched outward and supported on the ground. When the storage ladder is in a supporting form for achieving the effect of a straight ladder, the simultaneous support of the first ladder body and the second ladder body strengthens the supporting effect of the storage ladder on the ground. Compared with only one set of ladder frames supporting the ground, the stability of the storage ladder is stronger.

[0021] 2. The multi-form storage ladder for construction workers of the present application, when the first ladder body and the second ladder body are spread out as a herringbone ladder for single-person operation, the top end of the storage ladder is fixed by a first fixed structure respectively, and a number of connecting fabrics between the two ladder bodies are tightened to prevent the two ladder bodies from continuing to spread out. Compared with some traditional herringbone ladders that are fixed by rope stretching or hinged structures between the ladder frames on both sides, the storage ladder of the present application uses two methods to simultaneously fix its herringbone ladder shape, and is more stable.

[0022] 3. The multi-form storage ladder for construction workers of the present application is connected by multiple connecting fabrics between two ladder bodies. While fixing the ladder bodies, construction tools can be placed on them. Users can place more construction tools on the connecting fabrics, and a recessed part is set in the middle area of ​​the connecting fabrics. The tool storage effect is good and more convenient, which solves the problem that some traditional multi-functional ladders need others to deliver tools to them. Single-person operation also optimizes and facilitates the common operations of carrying / placing objects, making it more convenient to use. BRIEF DESCRIPTION OF THE DRAWINGS

[0041] Preferably, the connecting structure 3 is hinged on both sides to the top of the first ladder body 1 and the second ladder body 2, and the first ladder body 1 and the second ladder body 2 are respectively provided with a first fixed plate 11 and a second fixed plate 21 integral therewith on the upper part, the first fixed plate 11 is provided with a first fixed area 12 in the form of a notch, and the second fixed plate 21 is provided with a second fixed area 22 in the form of a notch.

[0042] Further, when the first ladder body 1 and the second ladder body 2 are forked and spread apart, the left side plate 41 and the right side plate 42 of the first fixing structure 4 are respectively inserted into the first fixing area 12 and the second fixing area 22 of the first fixing plate 11 and the second fixing plate 21 on both sides, and the top plate 43 at the upper end of the first fixing structure 4 is attached to the upper end of the connecting structure 3, so that the first fixing structure 4 fixes the first ladder body 1 and the second ladder body 2 in a cross-spreading state, wherein the first fixing area 12 and the second fixing area 22 respectively accommodate the left side plate 41 and the right side plate 42 with a wider gap area. 2 is inserted in a fitting manner, and when the storage ladder is in the shape of a herringbone ladder, the left side plate 41 and the right side plate 42 are respectively inserted in the first fixing area 12 and the second fixing area 22 and cannot be moved, so as to ensure the stable fixing effect of the first fixing structure 4 on the storage ladder in the shape of a herringbone ladder. The left side plate 41 and the right side plate 42 respectively penetrate from one side of the gap area and pass out from the other side, wherein the herringbone ladder is not a herringbone shape in a strict sense, but is specified / defined by the overall herringbone ladder shape of the first ladder body 1 and the second ladder body 2 and the shape function is the functional characteristics of the open-type herringbone ladder.

[0043] In some embodiments of the present application, a plurality of connecting fabrics 5 are connected between the plurality of crosspieces 8 between the first ladder body 1 and the second ladder body 2. The connecting fabrics 5 are hung on the crosspieces 8 via hooks 52 provided at both end edges so that the connecting fabrics 5 are detachably connected to the crosspieces 8.

[0044] The hook 52 and the connecting fabric 5 can be connected in various ways in the prior art. For example, after the hook 52 is inserted into the connecting fabric 5, the exposed part is a bolt and then screwed in with a nut to fix it.

Compared with a traditional straight ladder, this storage ladder is more stable, reliable and convenient to use.

[0050] Preferably, the bottom of the first ladder body 1 and the second ladder body 2 are respectively sleeved with a plurality of rubber support bodies 6 with a polyhedron at the bottom, and the bottom of the first ladder body 1 and the second ladder body 2 are attached to the ground with different faces of the polyhedron. Figure 6 , Figure 7 , the first flat surface 61 of the support body 6, the second flat surface 62 of the support body 6, and the third flat surface 63 of the support body 6; generally speaking, in the herringbone ladder shape of the storage ladder, one of the flat surfaces of the rubber support body 6 can be attached to the flat ground, and when the first ladder body 1 and the connecting structure 3 are fitted and fixed, when the second ladder body 2 is expanded to different degrees of adjustability, its rubber support body 6 can have multiple flat surfaces attached to the flat ground.

[0052] The working principle of a multi-form storage ladder for construction in this application:

[0053] 1. When the storage ladder is used as a herringbone ladder, the first ladder body 1, the second ladder body 2 and the connecting structure 3 are spread outward, and the first fixing structure 4 is inserted downward from the upper end of the connecting structure 3, and the left side plate 41 and the right side plate 42 are respectively inserted into the first fixing area 12 of the first fixing plate 11 of the first ladder body 1 and the second fixing area 22 of the second fixing plate 21 of the second ladder body 2, and the first ladder body 1, the second ladder body 2 and the connecting structure 3 are fixed in a cross state by using the matching snap-in state, and the first fixing structure 4 is attached to the upper end of the connecting structure 3. After the above-mentioned fixing, the plurality of connecting fabrics 5 are respectively hung on the horizontal rails 8 of the same layer on both sides through the hooks 52, and the plurality of connecting fabrics 5 are hung on the horizontal rails 8 just tightened by setting the length and play the role of stretching the two ladder bodies;

[0054] 2. When the storage ladder is supported on a vertical surface such as a wall and used as a straight ladder, the first ladder body 1 is fitted with the connecting structure 3, and the second fixing structure 7 is used to fit the two to fix the two. The second ladder body 2 is stretched outward and supported on the ground by the rubber support body 6. The rubber support bodies 6 of the first ladder body 1 and the second ladder body 2 are respectively supported on the ground. When the storage ladder is supported on a vertical surface and used as a straight ladder, the two ladder bodies are used to support the ground, and the supporting stability effect is better. The connecting fabric 5 is selectively connected to the cross bars 8 on both sides to play a tightening role when being straightened.

[0055] 3. Through the support of the two forms of the above-mentioned storage ladder, the connecting fabric 5 is used to stretch the ladder body to set a recessed part 51 in the middle area to play a storage function. Even if a single person uses the ladder, the construction tools can be placed in the recessed part 51 and taken at any time, which is very convenient and easy to use.

[0056] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention may be subject to various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
