Description
Technical field
The utility model relates to a kind of fixed mechanism, in detail, relates to the fixed mechanism that a kind of fan frame is used.
Background technology
Server relies on the running of radiator fan mostly and dispels the heat, however the radiator fan that is applied in the server be located in the fan frame more, and form radiator fan group with airflow.
Fan frame with a plurality of radiator fans is attached on the server shell base plate by screw mostly, can be provided with in the both sides of fan frame and be the stationary installation that bends sheet, this stationary installation can be incorporated into this fan frame by a bending end, and be attached on the chassis backplane by screw with another bending end, yet when radiator fan turns round, meeting produces vibrations and then makes a noise, in order to solve the problem of noise and vibrations, the simplest method is that a sheathed in advance elastic washer locks again in order to the screw that is attached to chassis backplane, reduces the generation of noise by the elastic washer shock-absorbing.
But elastic washer is located on screw will influence the effect that screw locks, and may produce the loosening phenomenon of screw because appended spiral shell bud number is not enough, thus, the loosening relative vibration that causes of coping screw be produced noise at chassis backplane.
In addition, elastic washer is subjected to the brute force extruding of screw, has been compressed to less thickness, and therefore the scope that institute can absorbing vibration also diminishes, and elastic washer easy elastic fatigue under the state that is subjected to powerful extruding for a long time.
Therefore, how to improve above various shortcoming, be the problem of demanding urgently now thinking deeply.
The utility model content
The fixed mechanism that provides a kind of fan frame to use is provided for the shortcoming of prior art in view of the above, a purpose of the present utility model, thereby has good shock-absorbing effect.
The fixed mechanism that provides a kind of fan frame to use is provided another purpose of the present utility model, thereby makes the vibration-absorptive material that is had have high durability.
The fixed mechanism that provides a kind of fan frame to use is provided a purpose more of the present utility model, thereby has shock-absorbing effect and height steadiness simultaneously.
For achieving the above object, the fixed mechanism that the utility model provides a kind of fan frame to use, be fixed in order to the fan frame that will be equiped with a plurality of radiator fans on the chassis backplane of electronic installation, at least one side of this fan frame is fixed in this chassis backplane by stationary installation, and this stationary installation has the first end that is fixed in this chassis backplane, reach the second end that vertically is connected with in this first end, it is characterized in that: this fan frame has the first relative bonding pad, and this stationary installation also has the second relative bonding pad at this second end, and this first, be provided with resilient snubber between two bonding pads, again the collocation run through this first, the elastic arc bar of two bonding pads and this resilient snubber make this resilient snubber be located in this first, between two bonding pads, simultaneously this stationary installation is incorporated into this fan frame, thereby makes this resilient snubber reduce the vibrations that produced because of the radiator fan running.
Elastic washer is subjected to the powerful extruding of screw and limited buffering effect only can be provided in the prior art, resilient snubber in the fixed mechanism that the utility model fan frame is used is located between this first and second bonding pad, and suffered extruding force comes from this elastic arc bar, can make the suffered extruding force of this resilient snubber unlikely excessive by the elastic arc bar of selecting suitable elastic force for use, and can have the elastic deformation amount many, thereby improve shockproof effect than prior art.In addition, because this elastic arc bar also has elasticity, therefore can extra elastic deformation amount be provided and then promote shockproof effect with this resilient snubber collocation.
In addition, elastic washer is easily because of flexible tired, the shortcoming that durability is low of the same deflection of long term maintenance in the prior art, the extruding force that resilient snubber in the fixed mechanism that the utility model fan frame is used is suffered is owing to have elasticity, therefore abundant elastic telescopic, and be difficult for the generation elastic fatigue.
Moreover, this stationary installation is incorporated into this fan frame by this elastic arc bar, and can be by such as general screw or take the lead screw (Thumb Screw) and be attached to this chassis backplane, and needn't must carry elastic washer secretly as the screw that is fixed in chassis backplane as the prior art, can make this stationary installation firmly be fixed in this chassis backplane.
As from the foregoing, the fixed mechanism that the utility model fan is used can improve the various shortcoming of prior art, therefore has high industrial utilization.
