Description

Centrifugal machine air shield and centrifugal machine Technical Field The utility model relates to the field of centrifuges, in particular to a centrifugal machine wind shield and a centrifugal machine. Background The centrifuge is an instrument for separating substances, belongs to laboratory basic equipment, and is widely used in the fields of life science, medicine, chemistry, environmental protection and the like. The wind shield device of the centrifugal machine is an important component part of the high-capacity centrifugal machine, the wind shield of the centrifugal machine and the rotating head of the centrifugal machine are fixed together and on a motor shaft, the wind shield can reduce air resistance generated when the horizontal rotating head rotates at a high speed, and the wind shield device is an important guarantee for guaranteeing stable operation of the centrifugal machine. The utility model provides a centrifuge wind shield structure of current modified, solves at present that the centrifugation is accomplished the back wind shield lid needs manual removal to lead to the loaded down with trivial details problem of operation step, adopts wind shield lid to hang on the wind shield connecting rod on the door closure through fixed cover activity, can open wind shield lid when opening the door closure, and wind shield lid accessible fixed cover and the cooperation of direction piece are automatic to be looked for and close with wind shield bottom. However, the top opening of the bottom of the wind shield of the centrifugal machine adopts a structure that a vertical side wall is combined with an inward flanging, so that the deformation resistance of the centrifugal machine is insufficient, when the centrifugal machine rotates at a high speed, the problems of uneven mass distribution of the edge of the bottom opening of the wind shield, deformation and the like can occur after long-time operation, so that crack defects are generated at the edge of the bottom opening of the wind shield, the expansion of the defects is easier to cause when the centrifugal machine rotates at a high speed, the operation safety and reliability are affected, and in addition, as the edge of the opening is inwards flanging, when a sample in the wind shield is taken out, hooking and collision are easy to occur with the flanging position, so that the sample is damaged, and the sample placement and taking efficiency are affected. Disclosure of utility model The utility model aims at overcoming the defects of the prior art, and provides a centrifugal machine wind shield, which changes the direction of a flanging by extending the flanging along the radial direction of a wind shield bottom shell to be folded outside a cavity, smoothly transits and links the flanging at the position of a top opening of the cavity, and when the flanging is positioned outside the cavity, the flanging is equivalent to adding an outward supporting structure at the position of the top opening of the wind shield bottom shell, so that the bending resistance and the torsion resistance of the structure can be improved, the deformation resistance can be improved, the problems of safety and reliability caused by deformation can be solved, and the position and the direction of the flanging can be changed, so that hooking and collision can not be generated with the flanging when a sample is taken and placed, and the problems of influencing the sample placement and taking efficiency and possibly damaging the sample can be solved. The first object of the utility model is to provide a centrifugal machine wind shield, which adopts the following technical scheme: including wind shield drain pan, wind shield drain pan inside forms open-top's cavity, and wind shield drain pan is equipped with the turn-ups at cavity open-top, and the turn-ups is turned over to the cavity outside along wind shield drain pan radial extension, and the cavity inner wall is in open-top position smooth transition and is linked up the turn-ups, and the turn-ups top forms the annular cooperation portion that is used for adapting wind shield lid.
