the two ladder main bodies are arranged side by side and are opposite in sliding opening, one end of each ladder main body is hinged, and the other end of each ladder main body is movably connected with the sliding groove of the main rod in each ladder main body through a supporting rod.

As a preferred embodiment of the angle-adjustable folding ladder, the chute is arranged in the main rod, one end of the chute is a closed end, and the other end of the chute is a through end of the main rod.

As an optimal implementation scheme of the folding ladder with adjustable angle of the utility model, the two ends of the supporting rod are provided with protrusions, and the size of the protrusions is matched with the concave points in the sliding groove of the main rod.

As an embodiment of the angle-adjustable folding ladder, the ladder main body is provided with a locking hole transversely penetrating through the main rod, and a locking rod arranged in the locking hole.

Advantageous effects

The utility model discloses the technique has following innovation advantage:

1. two ladder bodies are used, so that in use, one ladder can be replaced when damaged, and the damaged ladder body is placed at the bottom and the other ladder body is placed above.

2. The two ladder bodies are connected by a hinge, so that the angle of the ladder bodies can be adjusted.

3. After the ladder is adjusted to a desired angle, the supporting rod can be used for supporting, and then the protrusions at the end part of the supporting rod are combined with the concave points in the sliding groove for fixing and skid prevention.

4. The angle is adjustable, so that the application range of the device is wider, and the angle can be adjusted smoothly when the device faces the old or children.

Detailed Description

The present invention will be further explained with reference to the drawings and examples. These drawings are simplified schematic drawings and illustrate the basic structure of the present invention only in a schematic manner, and thus show only the components related to the present invention.

As shown in fig. 1 to 11, the present invention relates to an angle-adjustable folding ladder, which mainly comprises two main rods 1 and a ladder main body consisting of a cross rod 2 fixedly connected between the two main rods 1. the present invention provides two ladder main bodies for one ladder main body to be used as a ground chassis and one ladder for climbing (in the using process, the upper and lower structures of the two ladder main bodies can be exchanged). Every ladder main part all has two mobile jib 1, the inside of mobile jib 1 is equipped with spout 3, the cross section of spout 3 is "protruding" font, the length of spout 3 is close with the length of mobile jib 1, and the "protruding" font structure top of this spout 3 link up with the side surface of mobile jib 1 mutually, make the surface of mobile jib 1 form one with 3 length equal sliding exits 4 of spout (the structure of spout 3 can also be other structures, for example for doing spout 3 for a square or circular hole in mobile jib 1 inside, then set up a communicating mouth with inside square or circular shape hole and make sliding exits 4 also can on the outside surface of mobile jib 1). Meanwhile, at least two concave points 5 which are arranged downwards further at least are arranged in the sliding chute 3 along the inner wall of the sliding chute 3 (the number of the concave points 5 is at least two, and can be 2-100, the length of the sliding chute 3 in the main rod 1 is determined, and a fixed interval is reserved between every two concave points 5).

In the whole folding ladder with the adjustable angle, two ladder main bodies are arranged, after the independent ladder main bodies are completed according to the embodiment, the two ladder main bodies are aligned side by side, the sliding openings 4 of the two ladder main bodies are fixed in a relative state, and one ends of the two ladder main bodies are fixedly connected through the hinge 6, so that the angle can be adjusted by taking the hinge 6 as the center of a circle;

a branch rod 7 is also arranged, and the main rods 1 of the two ladder main bodies are connected through the sliding grooves 3 in the main rods 1. The two ends of the supporting rod 7 are arranged in the sliding groove 3, the two end points of the supporting rod 7 are provided with protrusions 8, and the shape and the structure of the protrusions 8 are matched with the concave points 5 and can slide back and forth in the sliding groove 3.

The chute 3 in the main rod 1 is in a through state at one end and in a closed state at the other end, and the supporting rod 7 enters the chute 3 from the through end; the through end of the main rod 1 is provided with a locking hole 9, and after the strut 7 is installed on the chute 3, a locking rod 10 is installed in the locking hole 9 to prevent the strut 7 from falling out of the chute.

The using method comprises the following steps: the whole equipment is placed at a needed position, any one ladder main body is used as a chassis, the other ladder main body is erected by taking the hinge 6 as a rotating center, the supporting rod connected through the protrusion 8 in the sliding groove 3 is used for supporting after the ladder main body reaches a specified angle, and the protrusion 8 at the two ends of the supporting rod 7 and the concave point 5 are used for fixing and preventing skidding during supporting.
