Abstract

The utility model provides a fixing structure for an improved frameless fan, which comprises a drive bearing seat, a buckling cover plate and a fan, wherein one end side of the drive bearing seat is convexly provided with a rotation rotary shaft which can be used for the combining part arranged on the fan to sheath and the other end side is provided with a containing part which can be used for a transmission component to assemble. In addition, the inner wall of the containing part is provided with a plurality of clamping grooves corresponding to a plurality of hooks arranged on the buckling cover plate; accordingly, when the utility model is assembled on an object to be assembled (such as radiation net holes of a power supplying device), the drive bearing seat and the buckling cover plate can be respectively arranged on both sides of the object to be assembled; accordingly, the clamping grooves arranged on the containing part of the drive bearing seat and the hooks arranged on the buckling cover plate are mutually buckled to make the drive bearing seat and the buckling cover plate quickly and stably clamped and arranged on the object to be assembled; the disadvantages of cost burden of an outer frame and complex screwing and fixation in installation are removed, and the disadvantages are caused by the phenomenon that a common radiation fan can just be integrally screwed on an object to be assembled when an outer frame is removed.
