Technical Field
[0001] This utility model relates to the field of fan technology, and in particular to a fan with an iron bracket. Background Technology
[0002] A fan is an electrical appliance that uses an electric motor to drive fan blades to rotate, thereby accelerating air circulation. Its core functions include cooling and air circulation. It consists of an AC motor, a fan blade assembly, and a gearbox. Its working principle is based on the rotation of an energized coil in a magnetic field. Traditional electric fans are essentially axial flow fans, meaning the airflow is parallel to the fan blade's rotation axis. An EC fan, on the other hand, refers to a fan driven by an EC motor.

[0018] The present invention will be further described in detail below with reference to the accompanying drawings.
[0019] A fan with an iron bracket 1, including an iron bracket 1, with a pulley provided below the iron bracket 1 for easy sliding.
[0020] The iron bracket 1 is provided with a grid outer ring 2, which includes four arc-shaped pieces 21. Each arc-shaped piece 21 has a connecting wall 212 on both sides, and the connecting walls 212 are fixed together by screws.
[0021] After the outer ring 2 of the grille is fixed as a whole, a grille bottom surface 3 is provided at its rear end. The grille bottom surface 3 includes a central grille 31 located in the middle and side grilles 32 located on both sides. The central grille 31 is circular vertically and parallel on both sides. The side grilles 32 fill the two sides of the central grille 31 to achieve a circular shape. A motor 4 mount 312 is provided in the middle of the front end face of the central grille 31, and the motor 4 is installed inside the motor 4 by screws.
[0022] An X-shaped arm 311 is integrally mounted on the middle grille 31 outside the motor base 312. A slot 211 is provided on the inner wall of the outer ring 2 of the grille (i.e., the inner wall of the middle part of the arc-shaped piece 21). A fixing seat 216 is provided at the front end of the slot 211, and a recessed column 217 with a threaded hole is provided on the fixing seat 216. A connecting column 315 with a threaded hole is provided on the inner side of the outer surface of the X-shaped arm 311, and two abutment pieces 316 are provided on the outer side. The front end of the X-shaped arm 311 is inserted into the slot 211, and a screw passes from the outside of the arc-shaped piece 21 inward through the recessed column 217 and into the connecting column 315 to fix the outer ring 2 of the grille and the middle grille 31.
[0023] Both sides of the front end face of the central grille 31 are provided with folded walls 313, and the folded walls 313 have several inverted trapezoidal holes 314. The side grilles 32 are provided with fixing hooks 321. Thus, after installation, the side of the side grille 32 abuts against the bottom surface of the folded walls 313 and the fixing hooks 321 pass through the trapezoidal holes 314. The outer edges of the central grille 31 and the side grilles 32 are fixed to the rear end face of the annular outer wall with screws.
[0024] At the midpoint of the connecting walls 212 at both ends of the arc-shaped wall, there is an inwardly recessed rectangular inner wall 213. The inner wall 213 has a bottom platform 214, with a semi-circular hole 215 in the middle of the platform. Two symmetrically arranged screw holes are located on the bottom surface. The inner wall 213 is mainly used for connection and fixation with the iron bracket 1. A fixing platform is fixed between the inner walls 213 on two adjacent arc-shaped pieces 21 via screw holes. The iron bracket 1 is connected and fixed to the fixing platform with bolts. Since the iron bracket 1 is only located on the left and right sides, the fixing platforms located at the top and bottom are unused.
[0025] A blade holder 5 is keyed onto the rotating shaft of the motor 4. Three radial strips 51 are mounted on the blade holder 5, spaced 120 degrees apart. Fan blades 6 are mounted between the radial strips 51 via screws. Embedding grooves 511 are provided on the outer walls of both sides of the radial strips 51. A fixing block 61 is provided at the inner end of the fan blade 6. Embedding blocks 612, which are adapted to the embedding grooves 511, are provided on both sides of the fixing block 61.
[0026] The blade seat 5 is provided with a cover 7, the radial strip 51 is provided with a through hole 512, and the cover 7 is provided with an outer hole 71 for screws to pass through the through hole 512.
[0027] A front inclined surface 62 is provided at the front end of the fixed block 61 along the rotation direction of the fan blade 6, and a rear inclined surface 63 is provided at the rear end. The inner wall of the front inclined surface 62 abuts against the outer wall of the blade seat 5, and the rear inclined surface 63 abuts against the outer wall of the cover 7.
[0028] The front end face of the outer ring 2 of the grille has multiple fixing grooves 22, each with a fixing hole 23. Fixing plates 24 are installed within the fixing grooves 22, each consisting of a straight section and a semi-circular section. The multiple fixing plates 24 are secured to the front grille cover 8 with screws, with the semi-circular section pressing against the front grille cover 8 for fixation.
[0029] A handle 9 is provided on the outer ring 2 of the grille, which allows the fan to be moved easily.
[0030] This specific embodiment is merely an explanation of the present utility model and is not intended to limit the present utility model. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but as long as they are within the scope of the claims of the present utility model, they are protected by patent law.
