[0002] Currently, modular furniture generally relies on adhesives or fasteners such as bolts, nuts, and screws to connect components during the assembly process. However, these installation methods have many shortcomings. While adhesives can secure furniture components, they are inconvenient to disassemble. Repeated disassembly and assembly of screws can lead to wear and enlargement of the threaded holes, affecting the connection's stability. In particular, if only bolts are used to connect wooden boards, when the diameter of the wooden board hole is larger than the bolt diameter, the bolt and the inner wall of the wooden board hole cannot fit tightly together. Without a structure to adjust the fit, the stability of the connection is reduced. Utility Model Content

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0023] Please see Figures 1 to 4 This utility model provides a technical solution: a connection structure for easy furniture installation and disassembly, comprising: a fixed cylinder 1; an adjusting screw 6 rotatably disposed inside the fixed cylinder 1; an adjusting outer cylinder 15 equidistantly threadedly connected to the outside of the adjusting screw 6, the adjusting outer cylinder 15 being slidably connected to the fixed cylinder 1; a fixed side plate 16 equidistantly fixed to the outside of the adjusting outer cylinder 15, the fixed side plate 16 being slidably connected to the fixed cylinder 1; an adjusting assembly disposed outside the fixed side plate 16, the adjusting assembly including an adjusting frame 17, the adjusting frame 17 being movably disposed outside the fixed side plate 16, the adjusting frame 17 being slidably connected to the fixed cylinder 1, an adjusting slide rod 2 being fixedly connected to the outside of the adjusting frame 17, the adjusting slide rod 2 being slidably connected to the fixed cylinder 1, one end of the adjusting slide rod 2 being fixedly connected to an inner top block 3; and a limiting assembly disposed at the top of the fixed cylinder 1.
[0024] It is understood that in this utility model, the fixing cylinder 1 is inserted into the hole in the wooden board. When inserted into the hole, each adjusting slide rod 2 and the inner top block 3 retract inward, and the adjusting slide rod 2 is in its deepest position inside the fixing cylinder 1 to facilitate the insertion of the fixing cylinder 1 into the hole in the wooden board. After insertion, one side of the fixing base 4 is pressed tightly against one side of one of the wooden boards. Then, the limiting plate 13 is inserted through the mounting hole 14 onto the outside of the limiting screw 11 and the limiting clamp 10. The fixing nut 12 is threaded onto the outside of the limiting screw 11 and is used to tighten the limiting plate 13 against one side of the other wooden board. Then, the rotating screw block 9 can be rotated. When the rotating screw block 9 rotates, it drives the worm gear 8 to rotate and adjust.
