FIG. 1 is a vertical cross-sectional view of a connecting gear of a printer drum core according to an embodiment of the present invention;
Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
The embodiment of the utility model provides a printer drum core connecting gear, including gear main part 1 and drum core coupling assembling 2, 1 one end of gear main part inserts in drum core coupling assembling 2's front end, drum core coupling assembling 2's rear end and drum core fixed connection, be provided with two screens pole 21 and elastic component 22 in the drum core coupling assembling 2, two screens pole 21 cross arrangement, its cross section passes through fixed axle 23 and fixes, fixed axle 23 both ends are fixed on drum core coupling assembling 2's inner wall, the front end of screens pole 21 is provided with buckle 211, with the draw-in groove 11 cooperation of gear main part 1, the rear end of screens pole 21 stretches out outside at drum core coupling assembling 2, elastic component 22 both ends are connected with two screens pole 21 respectively, make buckle 211 chucking in draw-in groove 11 through tension.
Adopt above-mentioned structure, buckle through screens pole 21 cooperates with the draw-in groove 11 of gear main part 1, make drum core coupling assembling 2 and gear main part 1 fixed connection, when needs installation or dismantlement drum core, press the rear end of screens pole 21, utilize lever principle to make the buckle 211 of screens pole 21 anterior segment break away from draw-in groove 11, loosen behind the rear end of screens pole 21, buckle 211 blocks again if in draw-in groove 11, can make things convenient for combination and separation of drum core coupling assembling 2 and gear main part 1 like this, accomplish the installation and the dismantlement of drum core then.
The gear body 1 is provided with a rotation stopping edge 12 which is matched with a rotation stopping groove 24 of the drum core connecting assembly 2, so that the joint of the gear body 1 and the drum core connecting assembly 2 is fixed and does not rotate. Meanwhile, the rotation stopping ribs 12 and the rotation stopping grooves 24 are matched to have a fool-proof function, so that the buckle 211 and the clamping groove 11 can be accurately aligned.
