Summary of the invention
Fundamental purpose of the present utility model is to provide a kind of end cap and removes and installs conveniently, effectively prevents latch-up structure fracture, and effectively prevents the carbon starch cylinder of end cap axial float.
For realizing above-mentioned fundamental purpose, the carbon starch cylinder that the utility model provides comprises the container body and the end cap that are roughly cylinder, and this container body has an axial open end, and end cap is removably installed in the open end of container body; Wherein end cap comprises sidewall and the end wall with the openend corresponding position of container body; Sidewall is provided with draw-in groove, and this draw-in groove comprises axial groove and circumferential slot, and wherein axial groove upwards extends from the bottom of the sidewall of end cap, and one end of circumferential slot is communicated with the top of axial groove; Container body is provided with the corresponding position of the draw-in groove on end cap the buckle coordinating with this draw-in groove; When buckle on container body coordinates with the circumferential slot of draw-in groove, this buckle is positioned at the minimum place of bottom spacing of the sidewall of circumferential slot and end cap; Between the end wall of end cap and the openend of container body, be equipped with a flexible sealing component, be used to the draw-in groove on end cap to provide axial restoring force with the coordinating of buckle on container body.
From above scheme, when end cap and container body are installed, make the relative container body of end cap first produce axially-movable, then produce and rotate in a circumferential direction, make the buckle of container body fall into the draw-in groove of end cap, under the effect of the restoring force of flexible sealing component, buckle by deduct firmly in the circumferential slot of draw-in groove with sidewall bottom apart from minimum place, effectively prevent the axial float of end cap; Between the openend due to the end wall at end cap and container body, be compressed with a flexible sealing component, can realize the sealing of the two, effectively prevent that carbon dust is from the two leakage; When dismounting, only need axle motion and the cooperation of the motion that rotates in a circumferential direction just can complete separating of end cap and container body; In whole assembly and disassembly process there is not deformation in buckle and draw-in groove, can effectively prevent that the latch-up structure being made up of draw-in groove and buckle from rupturing.In addition, the locking of this carbon starch cylinder has advantages of simple in structure.
A concrete scheme is that the axial groove of the draw-in groove of the sidewall of end cap upwards extends vertically from the bottom of the sidewall of this end cap.
Another concrete scheme is, the circumferential slot on the sidewall of end cap from the top of the axial groove of draw-in groove to the other end of circumferential slot gradually near the bottom of the sidewall of end cap.
Another concrete scheme is, the necking section that the top connectivity part of the circumferential slot of the draw-in groove on the sidewall of end cap and the axial groove of this draw-in groove is this draw-in groove.
From above scheme, due to the connectivity part of axial groove and the axial groove necking section that is draw-in groove, so can provide better guarantee to draw-in groove and coordinating of buckle, the circumferential play that can effectively limit end cap that coordinates by buckle with draw-in groove.
One more specifically scheme be that wherein flexible sealing component is resilient seal sponge ring.
Another more specifically scheme be on the end wall of end cap, to be provided with the groove matching with flexible sealing component.
From above scheme, owing to being provided with a groove matching with flexible sealing component on end wall,, only flexible sealing component need be placed in to groove, then assemble with container body during with container body at assembling end cap, facilitate the assembling between three.
