[0002] As consumer demand for electric fans becomes increasingly diverse, the variety of electric fan products on the market is also growing. In large public places such as shopping malls and train stations, floor fans with high wind speeds and strong airflow are commonly used for ventilation. Traditional floor fans mostly consist of a fan head and a floor base. To ensure a secure connection between the two, they often employ a non-removable fixing method or a complex connection structure. This not only increases production costs, but the non-removable nature also results in floor fans being bulky and taking up a lot of space during transportation, making them inconvenient to transport. Utility Model Content

[0003] The purpose of this utility model is to provide a connecting structure for floor fans, which aims to solve the problems of complex connecting structures, troublesome disassembly and assembly, and inconvenient transportation in existing floor fan technologies.

[0004] This utility model provides a connecting structure for a floor fan, including a connecting assembly consisting of a connecting piece and a nut for fixed connection. The connecting piece is fixed to both sides of the inner side of the rear grille. The connecting piece is characterized by having a through hole in the middle, with a nut inside the through hole. The nut has an internal thread, one end of which is fixedly connected to the connecting piece, and the other end of which protrudes outside the rear grille. A fixing piece is provided at the protruding end of the nut. A support member is connected to the lower end of the fixing piece, and a through hole is provided at the upper end of the fixing piece. The size of the through hole is larger than the diameter of the internal thread of the nut. A screw is fitted into the through hole at the upper end of the fixing piece. The outer diameter of the screw nut is larger than the diameter of the through hole at the upper end of the fixing piece, and the screw shank passes through the through hole at the upper end of the fixing piece and is connected to the nut by thread.

[0005] Furthermore, the connecting piece is an arc-shaped metal sheet, the curvature of the connecting piece is in contact with the inner edge of the rear mesh cover, the connecting piece is perpendicularly welded to the mesh cover wire on the rear mesh cover, the through hole of the connecting piece is located between two adjacent mesh cover wires welded to the connecting piece, and the diameter of the through hole of the connecting piece is smaller than the distance between two adjacent mesh cover wires at the welding point of the connecting piece.

[0006] Furthermore, the nut and the connecting piece are connected by riveting, with the riveting fixed at one end of the nut and the other end of the nut passing through two mesh wires adjacent to the welding point of the connecting piece and protruding outside the rear mesh cover.

[0007] Furthermore, a washer is fitted over the end of the nut that protrudes beyond the mesh cover. The inner diameter of the washer is the same as the outer diameter of the nut, and the length of the washer is greater than or equal to the length of the nut protruding beyond the mesh cover.

[0008] Furthermore, the washer is made of an elastic material with a hardness of 70A-90A.

[0009] Furthermore, the screw is a plastic hand-tightening screw.

[0010] This invention uses screws to movably connect the fixing plates on both sides of the support frame to the rear grille. During connection, simply align the fixing plates and washers, insert the screws into the through holes of the fixing plates and washers, and rotate the screws to thread the screw shanks into the nuts of the connecting components, thus connecting the support frame and the fan head. When transporting or storing, loosen the screws on both sides of the floor fan by hand, remove it from the fan, and remove the fan head from the fixing plates at both ends of the support frame to separate the fan head from the support frame, thus facilitating better storage and transportation. In summary, this invention has a simple structure, low production cost, easy fan assembly and disassembly, and a secure connection.
