Abstract
The utility model provides a kitchen knife device, comprising a kitchen knife and a chopping block, wherein, the kitchen knife consists of a knife body and a knife handle. The utility model is characterized in that the chopping block is provided with a support base which is in detachable connection with the knife body of the kitchen knife by a pivot rotation mechanism. Because the knife body of the kitchen knife is in detachable and rotary connection with a screw of the support base through a through hole, when the utility model is used, the screw of the support base is inserted in the through hole of the knife body of the kitchen knife, and the kitchen knife takes the joint between the through hole and the screw as a rotary pivot, in this way, the kitchen knife is used as a 'guillotine'; based on the lever principle, cutting food is quite labor-saving by the kitchen knife, thereby easily cutting the food and facilitating to cut hard foods; when the kitchen knife is not in rotary connection with the support base, the kitchen knife can be used as a general kitchen knife; moreover, the front part of the chopping plate is also provided with a knife grinding mechanism, by which both surfaces of the knife edge can be simultaneously ground, thereby the knife grinding process can be finished at one time; moreover, the knife grinding is also convenient and quick.
Description
Technical field
The utility model relates to a kind of kitchen knife device, more particularly, relates to a kind of kitchen knife device easy to use.
Background technology
Existing kitchen knife device generally comprises kitchen knife and chopping block, and kitchen knife is made of cutter hub and hilt, and kitchen knife and chopping block are separated from one another, when with the harder food of kitchen knife cutting, can only impact cutting, use inconvenient, also require great effort very much, and dangerous, even blade is damaged.
Simultaneously, when the blade of kitchen knife is not sharp, kitchen knife must be taken on the whetstone and be tempered, this makes troubles also for the use of kitchen knife.
Summary of the invention
The technical problems to be solved in the utility model is to improve on the basis of above-mentioned existing kitchen knife device, thereby a kind of kitchen knife device easy to use is provided.
In order to solve the problems of the technologies described above, the technical solution adopted in the utility model is as follows:
A kind of kitchen knife device comprises kitchen knife and chopping block, and kitchen knife is made of cutter hub and hilt, it is characterized in that: chopping block is provided with a bearing, removably is rotationally connected by a fulcrum rotating mechanism between the cutter hub of kitchen knife and the bearing.
Described fulcrum rotating mechanism comprises screw and through hole, and above-mentioned screw fixings leaves the gap that can hold kitchen knife cutter hub thickness between the head of a nail of screw and the bearing on bearing; Above-mentioned through hole is located on the front portion of kitchen knife cutter hub, and the diameter of through hole is greater than the diameter of the screw head of a nail; The cutter hub of kitchen knife by above-mentioned through hole removably with bearing on screw be rotationally connected.
Since the cutter hub of kitchen knife by through hole removably with bearing on screw be rotationally connected, so, during use, as long as will overlap on the screw of the through hole on the kitchen knife cutter hub on the bearing, kitchen knife is that the junction of through hole and screw is a rotating fulcrum with the junction of itself and bearing, at this moment, kitchen knife becomes " chopper ", utilizes the principle of lever, makes kitchen knife become very laborsaving to the cutting of food, thereby easily food is cut, help the cutting of harder food; When kitchen knife was not rotationally connected with bearing, kitchen knife can use as common kitchen knife
Described bearing preferably is located on the middle part of chopping block front end, and the screw of described fulcrum rotating mechanism preferably is positioned on the middle part of chopping block front end.Like this, when through hole on the cutter hub and the screw on the bearing were rotationally connected, cutter hub was positioned on the middle part of chopping block, was convenient to the cutting of food.
The place ahead of through hole is communicated with another small through hole on the described cutter hub, the diameter of above-mentioned small through hole greater than the diameter of screw ailing body less than the diameter of the screw head of a nail.After the through hole on the cutter hub is enclosed within on the screw by the screw head of a nail, with the past post-tensioning of cutter hub, above-mentioned small through hole and screw ailing body are rotationally connected, like this, since the diameter of above-mentioned small through hole greater than the diameter of screw ailing body less than the diameter of the screw head of a nail, so the front end of cutter hub is limited on the screw ailing body between the bearing and the screw head of a nail, prevented that cutter hub in the cutting process breaks away from the generation of screw phenomenon.
As further improvement of the utility model, the front portion of described chopping block is provided with a sharpening mechanism.
Described sharpening mechanism comprises two slots, two connecting rods and two conical small-sized whetstones, and above-mentioned slot is located on the chopping block, fixedlys connected with connecting rod top in the bottom of above-mentioned small-sized whetstone, and the connecting rod bottom is inserted in the slot; The trochoidal surface of two small-sized whetstones contacts and makes two small-sized whetstones be the setting of " V " type.Like this, when the blade of cutter hub when mill is moving back and forth between two small-sized whetstones, two small-sized whetstones just temper two faces of blade simultaneously, make disposable the finishing of whetting a knife, and it is convenient, fast to whet a knife.
For the trochoidal surface that makes two small-sized whetstones can closely contact, a back-moving spring is installed between the bottom of described two connecting rods, one end of back-moving spring is installed on the bottom of a connecting rod, and the other end of back-moving spring is installed on the bottom of another root connecting rod.
The utility model beneficial effect against existing technologies is, since the cutter hub of kitchen knife by through hole removably with bearing on screw be rotationally connected, so, during use, as long as will overlap on the screw of the through hole on the kitchen knife cutter hub on the bearing, kitchen knife is that the junction of through hole and screw is a rotating fulcrum with the junction of itself and bearing, at this moment, kitchen knife becomes " chopper ", utilize the principle of lever, make kitchen knife become very laborsaving, thereby easily food is cut, help the cutting of harder food the cutting of food; When kitchen knife was not rotationally connected with bearing, kitchen knife can use as common kitchen knife.Simultaneously, also be provided with a sharpening mechanism on the front portion of chopping block, this sharpening mechanism can be simultaneously tempers two faces of blade, makes disposable the finishing of whetting a knife, and it is convenient, fast to whet a knife.
Kitchen knife device of the present utility model has changed traditional kitchen knife device incision of food and the form of whetting a knife and being separated, incision of food and sharpening are organically combined, make the use of kitchen knife device convenient, just be applicable to kitchen application more, fill up the market vacancy, had certain market value and certain social benefit.
