According to the kitchen knife with the replaceable cutting edge, the elastic curved surface structure of the mounting pin piece or the cutting edge is utilized, and the mounting pin piece is inserted into the cutting edge mounting groove to achieve the effects of stabilizing and clamping under the action of the elasticity of the mounting pin piece or the cutting edge after the mounting pin piece is inserted into the cutting edge mounting groove, so that the precision requirement between the mounting pin piece and the cutting edge mounting groove is reduced, and the industrial production is facilitated.
Description
Technical field
The utility model relates to a kind of cutter, especially a kind of kitchen knife of cutting edge replaceable.
Background technology
The blade of cutter is along with using rust gradually, and then impact is used, although blade is polished and can again be improved its sharpness, but along with the increase of polishing number of times, can make blade more and more be difficult to repair, and, there are some blades when damage is comparatively serious, can repair completely, once and blade is scrapped, whole cutter has just lost effect substantially.For this reason, applicant had once studied a kind of kitchen knife application utility model patent of cutting edge replaceable, in this technology, split type blade is to coordinate with special impression by special-shaped double wedge with blade, and install in conjunction with screw, although such structure can be changed blade,, screw has affected the use of cutter, and have hygienic issues, and special-shaped double wedge has goodish precision with needing both coordinating of special impression in the time producing, this has caused difficulty to processing, is unfavorable for implementing.
Summary of the invention
The purpose of this utility model is: a kind of kitchen knife of cutting edge replaceable is provided, and it is low to the required precision of producing, and installation, the convenient disassembly of blade and blade are simple, can not affect the normal use of cutter, to overcome the deficiencies in the prior art.
The utility model is achieved in that the kitchen knife of cutting edge replaceable, comprise handle of a knife, blade, be provided with blade mounting groove in the bottom of blade, in blade mounting groove, be provided with segmentation reinforcement, segmentation reinforcement and blade are connected as a single entity, and blade mounting groove is divided into segmentation structure by segmentation reinforcement; Separately be provided with independently blade, be provided with corresponding with blade mounting groove shape and can insert the mount pin sheet of blade mounting groove at the top of blade, mount pin sheet or blade are curved-surface structure and have elasticity; Or mount pin sheet and blade are curved-surface structure and have elasticity.
One end at blade mounting groove is provided with draw-in groove, is provided with snap fit at the other end of blade mounting groove, and snap fit is fixed on blade by shipping and reselling on another market, and is connected with spring or shell fragment button at the end of snap fit, and spring or shell fragment button are arranged in blade; Be provided with corresponding installing port in the rear and front end of mount pin sheet.Improve the stability that blade is installed, ensure to use reliably, and do not affect operation.
Every section of described blade mounting groove is the arc groove caving inward.This shape is not only easy to make, and if while having mount pin sheet to break in blade mounting groove, can utilize the level and smooth camber line of circular arc that sliver is ejected from the side of blade mounting groove.
Draw-in groove is communicated with the outer end of blade.When such structure can be in mount pin sheet breaks at draw-in groove, from the external port of blade, the part of fracture is ejected draw-in groove.
In the utility model, the curved-surface structure of mount pin sheet or blade
Owing to having adopted technique scheme, compared with prior art, the utility model blade mounting groove is set to segmentation structure, has both effectively raised intensity and the stability in use of blade mounting groove, is also convenient to produce; Corresponding mount pin sheet or blade adopt globoidal structure, and be with flexible, in the time that mount pin sheet is inserted to blade mounting groove, utilize the difference on blade mounting groove and mount pin plate shape, by external force, mount pin sheet is inserted in blade mounting groove by force, mount pin sheet is under the elastic reaction of self or blade, or in conjunction with both common elastic reactions, mount pin sheet is tightened in blade mounting groove, play the stable effect fixing, thereby reduce the quality of fit requirement between mount pin sheet and blade mounting groove, be convenient to suitability for industrialized production.The utility model is simple and reliable for structure, with low cost, and result of use is good.
