[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field are within the scope of protection of the present invention.

[0022] Example 1

[0023] The utility model provides a multi-angle connection structure, which includes a connecting member 1 and a main body 2 and a main body 3 located in front and behind the connecting member 1. The connecting member 1 and the main body 2, as well as the connecting member 1 and the main body 3, can be detachably connected, that is, the main body 2 and the connecting member 1, as well as the main body 3 and the connecting member 1, form a detachable connection.

[0024] At the same time, the connection member 1 and the main body 1 2, and the connection member 1 and the main body 2 3 are positioned by the cooperation of the recess group 4 and the convex group 5. The main body 1 2 and the main body 2 3 can rotate relative to the connection member 1. After rotation, they are positioned by the cooperation of the recess group 4 and the convex group 5, and then locked and fixed, so that the connection angle between the main body 1 2, the main body 2 3 and the connection member 1 can be adjusted.

[0025] In this embodiment, a convex portion group 5 is provided at the front and rear positions of the inner side surface of the connecting member 1, and a concave portion group 4 is provided on the outer side surfaces of the main body 1 2 and the main body 2 3 to cooperate with the corresponding convex portion group 5. Each convex portion group 5 is composed of a plurality of convex portions 51, and each concave portion group 4 is composed of a plurality of concave portions 41. The convex portions 51 of the same convex portion group 5 and the concave portions 41 of the same concave portion group 4 are distributed in the same annular array, so that after the convex portion group 5 and the concave portion group 4 are rotated to each other by a certain angle, the concave portions 41 and the convex portions 51 can still correspond one to one, so that the main body 1 2 and the main body 2 3 are positioned with each other through the connecting portion, and the angles between the main body 1 2 and the connecting member 1, and between the main body 2 3 and the connecting member 1 can be adjusted and set, thereby finally realizing multi-angle connection.

[0026] In this embodiment, the recess 41 is a positioning hole, and a mounting hole 8 is opened on the plate 11, the main body 1 2 or the main body 2 3. A positioning shaft or a positioning pin is installed in the mounting hole 8 as a protrusion 51, so that the protrusion 51 can be inserted into the recess 41 to form a positioning fit. The bottom of the positioning shaft or the positioning pin is screwed into the mounting hole 8 by a threaded connection, and the top thereof serves as a raised part as the protrusion 51.

[0027] Furthermore, an inverted cone-shaped groove is provided at the top of the convex portion 51, and a conical protrusion is provided at the center of the bottom of the positioning hole. When the concave portion 41 and the convex portion 51 cooperate with each other, the protrusion and the groove cooperate with each other to form further positioning to prevent displacement between the concave portion 41 and the convex portion 51.

[0028] In this embodiment, the connecting member 1 includes a plate body 11 and a fastening bolt 12. The plate body 11 is in the shape of a long waist with arc-shaped ends. The convex group 5 is arranged along the corresponding arc shape, that is, the two convex groups 5 are respectively located on the inner side surfaces of the two ends of the long side of the long waist-shaped plate body 11; the plate body 11 is provided with a through hole 1 6 at the center of each convex group 5, and the main body 1 2 and the main body 2 3 are respectively provided with a through hole 2 7. The fastening bolt 12 passes through the through hole 1 6 and is screwed with the through hole 2 7, thereby realizing the locking and fixation between the main body 1 2, the main body 2 3 and the connecting member 1. When the angle adjustment between the main body 1 2 or the main body 2 3 and the connecting member 1 is completed, the fastening bolt 12 can be used for locking and fixation, so that the main body 1 2, the main body 2 3 and the connecting member 1 are fixed at this angle. When the angle needs to be adjusted or disassembled, the fastening bolt 12 is loosened first, and then the convex group 5 and the recessed group 4 can be separated.

[0029] In this embodiment, the front and rear ends of the plate body 11 are both arc-shaped, that is, rounded ends, which can also prevent injuries to hands during disassembly.

[0030] Furthermore, the height of two opposing convex portions 51 in each convex portion group 5 is higher than that of the other convex portions 51. In this embodiment, the convex portions 51 of the convex portion group 5 form an annular array, that is, they are arranged in a circle, wherein the protruding portions of any two convex portions 51 on the same diameter are higher than the other convex portions 51 in the same group. The purpose of such a design is that when the convex portion group 5 and the concave portion group 4 are rotated relative to each other by an angle, the cooperation between the two convex portions 51 and the corresponding concave portions 41 is more stable, that is, the cooperation between the entire convex portion group 5 and the concave portion group 4 is more stable, forming further positioning to prevent displacement between the concave portion group 4 and the convex portion group 5.

[0031] Furthermore, the head of the fastening bolt 12 is provided with a hand-grip end 121 for easy manual rotation. In this embodiment, a circular cover is used to facilitate manual rotation of the fastening bolt 12.

[0032] The present invention also provides a modular ladder comprising at least two ladder segments 9, each of which can be shaped in various shapes. Side beams 91 are provided on either side of each ladder segment 9, with parallel horizontal bars disposed between the two side beams 91. The ends of the side beams 91 on the same side of two adjacent ladders are formed with a main body 2 and a second main body 3, respectively. The main body 1 2 and the second main body 3 are connected by a connector 1, thereby forming an angle-adjustable connection between the two ladder segments 9. The main bodies 1 2, 2, and connectors 1 on the two side beams 91 of the same ladder segment 9 are symmetrically arranged. Thus, the angles of two or more ladder segments 9 can be adjusted as needed to create structures with different shapes.

[0033] Furthermore, the widths of the side beams 91 and the plate body 11 are consistent, which improves the integrity and appearance.

[0034] Example 2

[0035] The basic content is the same as that of Example 1. In Example 1, convex groups 5 are provided at the front and rear positions of the inner side surface of the connecting member 1, while in this embodiment, concave groups 4 are provided. The outer sides of the main body 1 2 and the main body 2 3 are provided with convex groups 5 that cooperate with the concave parts 41 of the corresponding concave groups 4, that is, the concave groups 4 are provided on the plate body 11 of the connecting member 1, and convex groups 5 are provided on the corresponding main body 1 2 and the main body 2 3.

[0036] Example 3

[0037] The basic content is the same as that of Example 1, with the difference being that a convex group 5 and a concave group 4 are respectively provided at the front and rear positions of the inner side surface of the connecting member 1, and corresponding concave groups 4 and convex groups 5 are provided on the outer sides of the main body 1 2 and the main body 2 3, that is, the two groups on the plate body 11 of the connecting plate can be a convex group 5 and a concave group 4, and whether the convex group 5 or the concave group 4 is provided at the front and rear ends can be arbitrarily selected, and can be provided correspondingly to the main body 1 2 and the main body 2 3.

[0038] Example 4

[0039] The basic content is the same as the above three embodiments, the difference is that the convex portion 51 and the concave portion 41 can be set in the same concave portion group 4, that is, the convex portion 51 and the concave portion 41 can be mixed in the same concave portion group 4. Similarly, the convex portion 51 and the concave portion 41 can be mixed in the same convex portion group 5, as long as the convex portion group 5 and the concave portion group 4 can cooperate with each other.

[0040] In short, the protrusions 51 , recesses 41 , protrusion group 5 and recess group 4 can be matched arbitrarily as long as they can achieve the purpose of mutual coordination.

[0041] The present invention is not limited to the above-mentioned optimal implementation mode. Anyone can derive other forms of products under the inspiration of the present invention. However, no matter what changes are made in the shape or structure, any technical solution that is the same or similar to that of the present application falls within the scope of protection of the present invention.
