The utility model solves the problems of the technologies described above adopted technical scheme: a kind of dismountable direct current machine, comprise the bonnet of columniform shell body and disc structure, the bottom of described shell body is provided with the flanging bent inwards, described bonnet comprises inner cap body and outer cover, described outer cover is pressed in below flanging, described flanging is looped around the outer peripheral face of inner cap body, the periphery of described inner cap body is provided with multiple notch accommodating locking nut, the bottom surface of described notch and the end face of described flanging are positioned in same level, described locking nut is square plate body structure and four angles is provided with downward projection, described locking nut matches with fixed screw, the bottom surface of described notch is provided with through hole, projection on locking nut is separately fixed on flanging and notch through through hole by fixed screw,
During installation, locking nut is positioned at notch, described bonnet is pressed in the below of flanging, fixed screw is locked after moving through the through hole outside housing sidewall of locking nut acted in notch, now locking nut respectively has two projections to be positioned on flanging and notch, during dismounting, fixed screw screws out from locking nut, and locking nut clawback is in notch simultaneously.
Described locking nut is provided with the screwed hole adapted with fixed screw, under the state that described screwed hole is corresponding with described through hole, locking nut wherein two projections is positioned on flanging, another two projections of locking nut are positioned at notch, under the state that described locking nut is positioned at notch, four projections of locking nut are positioned at notch bottom surface.The setting that locking nut four is protruding, even if make to there is height error between the bottom surface of notch and the end face of flanging, also can fix compression bonnet by four projections, comparatively stable after making bonnet fixing.
Four angles of described locking nut are bent downwardly.Four angles of locking nut are bent downwardly rear formation four projections.
The diameter of described outer cover is greater than the annular diameters of described flanging, and the diameter of outer cover is less than the diameter of described shell body, and the diameter of described inner cap body and the annular diameters of described flanging adapt, and described inner cap body exceeds described flanging.Outer cover is so set and inner cap body is to adapt with the size of shell body.
The periphery of described inner cap body is provided with two notches, and two described notches are symmetrical arranged.Two symmetrically arranged notches can ensure to install stable preferred structure.
Compared with prior art, the utility model has the advantage of that shell body is provided with flanging to match with bonnet, bonnet is provided with the notch accommodating locking nut, locking nut will be fixed and be pressed on notch and flanging, bonnet and shell body will be locked thus.And locking nut is square plate body structure and four angles are provided with downward projection, locking nut contacts with notch, flanging by four projections.I.e. four points of four projections, can fix a plane, even if there is height error between the bottom surface of notch and the end face of flanging, also can fix compression bonnet by four projections, stable after making bonnet fixing, can not be moved or deflect.
