Abstract
The utility model relates to an eccentric self-locking base circle blade of a paper cutter. The eccentric self-locking base circle blade comprises a base circle blade and a base circle cutter shaft, wherein the base circle cutter shaft is arranged inside the base circle blade; the base circle blade is circular ring-shaped; an eccentric groove is formed at the inner periphery of the base circle blade; a long key groove is formed at the outer periphery of the base circle cutter shaft; a woodruff key is formed between the eccentric groove in the base circle blade and the long key groove on the base circle cutter shaft; after the position of the base circle blade on the base circle cutter shaft is determined according to the requirement of the paper cutting dimension, the base circle blade is rotated; and at this moment, the woodruff key slides relatively in the eccentric groove of the base circle blade so that the base circle blade is locked. In use, the eccentric self-locking base circle blade will become tighter; when the eccentric self-locking base circle blade needs to be detached, the base circle blade is rotated in the reverse direction; and the eccentric self-locking base circle blade is simple in structure, convenient for detaching and long in service life.
Description
Technical field
The utility model relates to a kind of paper cutter bottom round blade sheet, specifically, relates to a kind of paper cutter eccentric self-locking bottom round blade sheet.
Background technology
At present, original paper cutter bottom round blade sheet, except blade had an angle, integral body was a cylinder, by special-purpose cast iron hoop, one side fluting, bore conical bore, realize the fastening of dise knife and dismounting with the degree of tightness of taper bolt, often occur becoming flexible, the phenomenon of corrosion, service life is short, installs, adjusts, dismantles extremely inconvenient.
The utility model content
The technical problems to be solved in the utility model is for above deficiency, and the paper cutter eccentric self-locking bottom round blade sheet of a kind of simple in structure, convenient disassembly, long service life is provided.
In order to solve above technical problem, the technical solution adopted in the utility model is as follows: a kind of paper cutter eccentric self-locking bottom round blade sheet, comprise bottom round blade sheet and bottom round blade axle, the bottom round blade axle is arranged on the inside of bottom round blade sheet, the bottom round blade sheet is circular, the bottom round blade sheet interior week be provided with eccentric grove, the periphery of bottom round blade axle is provided with long keyway, is provided with Woodruff key between the eccentric grove in the bottom round blade sheet and the long keyway on the bottom round blade axle.
the utility model is taked above technical scheme, have the following advantages: paper cutter eccentric self-locking bottom round blade sheet comprises bottom round blade sheet and bottom round blade axle, the bottom round blade axle is arranged on the inside of bottom round blade sheet, the bottom round blade sheet is circular, the bottom round blade sheet interior week be provided with eccentric grove, the periphery of bottom round blade axle is provided with long keyway, be provided with Woodruff key between eccentric grove in the bottom round blade sheet and the long keyway on the bottom round blade axle, requirement according to the cut paper size, determine that the bottom round blade sheet is behind the position on the bottom round blade axle, rotate the bottom round blade sheet, at this moment, Woodruff key is relative sliding in bottom round blade sheet eccentric grove, can lock the bottom round blade sheet.During use, use tighter and tighter; When needs were dismantled, counter-rotation bottom round blade sheet got final product, simple in structure, convenient disassembly, long service life.
The utility model is described in further detail below in conjunction with drawings and Examples.
