when the driving roller 601 moves the CT scanner frame 3 toward the scanner bed 7, a vibration occurs, and the pressure reducing spring 2065 acts on the pressure reducing inner cylinder 2063 through the one-way valve plate 2064, and is affected by the vibration, the pressure reducing inner cylinder 2063 will perform a corresponding telescopic action inside the inner lining layer 2062, when the pressure reducing inner cylinder 2063 performs an upward movement stretching movement inside the pressure reducing outer cylinder 2061, the pressure intensity below the one-way valve plate 2064 will decrease, the one-way valve on the one-way valve tube 207 will open, air will be sucked into the pressure reducing outer cylinder 2061, when the pressure reducing inner cylinder 2063 performs a downward movement retracting movement inside the pressure reducing outer cylinder 2061, the one-way valve plate 2064 will open under the action of pressure as the pressure below the one-way valve plate 2064 gradually increases, and the air inside the pressure reducing outer cylinder 2061 will enter the main frame 1 through the vent hole 208, then, the hot air flows into the filling cotton 201 through the air inlet holes 205, because the hot air has the floating characteristic, the flow velocity of the hot air flowing into the filling cotton 201 through the air inlet holes 205 towards the heat dissipation holes 204 is increased, the decompression spring 2065 deforms through the telescopic motion of the decompression inner cylinder 2063 in the decompression outer cylinder 2061, the elastic force generated when the decompression spring 2065 deforms is utilized, and the inner liner 2062 is matched, so that the vibration upward transmission strength generated by the rolling of the driving roller 601 can be weakened, the strength of the main shaft bearing 202 under the vibration action can be further weakened by the filling cotton 201, the vibration resistance and the impact resistance of the main shaft bearing 202 in the operation process of the CT scanning frame 3 are effectively improved, the stability of the CT scanning frame 3 is ensured, and the daily maintenance cost of the CT scanner is reduced.
The above description is only for the preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art should be able to cover the technical scope of the present invention and the equivalent alternatives or modifications according to the technical solution and the inventive concept of the present invention within the technical scope of the present invention.
