Abstract
The invention discloses a household kitchen knife grinding device. In the kitchen knife grinding device, a through hole communicated with the front and the back is formed on the upper surface of a grinding device body; grinding wheels consist of two same grinding wheels; a V-shaped gap is formed between the two grinding wheels; positioning sleeves are fixedly arranged at the axle centers of the two grinding wheels; a key slot is formed between the inner holes of the positioning sleeves so as to form a sliding fit relationship with a key; the two same grinding wheels are arranged on the upper surface of a drive shaft through the positioning sleeves; a sliding key is fixedly arranged in the key slot of the drive shaft; by the sliding key, the grinding wheels only have the freedom degree of sliding leftwards and rightwards but have no freedom degree of mutually rotating on the drive shaft; springs are arranged at the two ends of the drive shaft and the two sides of each grinding wheel; the springs are compressed by nuts arranged on the drive shaft; the drive shaft is arranged at the position of a gap on the grinding device body through a bearing; a speed changer is fixedly arranged in the grinding device body; the output end of the speed changer is fixedly connected with the drive shaft; and a handle is fixedly arranged at the position of the through hole communicated with the front and the back of the grinding device body.
Description
Technical field
The present invention relates to a kind of device that sharpens a kitchen knife, particularly a kind of family expenses device that sharpens a kitchen knife belongs to the domestic appliance technical field.
Background technology
For a long time, when kitchen knife was no longer sharp, the general method that adopts was exactly on whetstone, to carry out manual method of tempering, and not only there is inefficiency in this method, simultaneously, exist the blade that tempers inhomogeneous, or blade tempers the effect defect of bad.
Summary of the invention
The objective of the invention is to: a kind of family expenses device that sharpens a kitchen knife is provided, and it is inhomogeneous to overcome existing family existing blade that tempers when tempering kitchen knife, or blade tempers the effect defect of bad.
The present invention realizes that the technical scheme that above-mentioned purpose adopts is: a kind of family expenses device that sharpens a kitchen knife, and the knife sharpener body is the load bearing component that is installed on the location of all parts, by adopting injection moulding or metal material to make; The through hole that connects before and after on the knife sharpener body, having, emery wheel is made up of two identical institutes, during being close together of the axis coinciding of two identical emery wheels; Form the breach of V-type between two emery wheels, the axis part of two emery wheels installs and fixes positioning sleeve, and that fixing between positioning sleeve and the emery wheel can adopt is bonding, also can adopt interference fit method to fix; Between the endoporus of positioning sleeve, make keyway so that form the relation be slidingly matched with key, two identical emery wheels through positioning sleeve be installed in power transmission shaft above; In the keyway of power transmission shaft, install and fix feather key; Feather key makes the free degree that emery wheel only horizontally slips and does not have the free degree of mutual rotation on power transmission shaft, at the two ends of power transmission shaft, the both sides mounting spring of emery wheel, spring is compressed by the nut that is installed on the power transmission shaft; Power transmission shaft is installed in the gap portions of knife sharpener body through bearing; Install and fix a speed changer in the inside of knife sharpener body, the output of fast device is connected fixing with power transmission shaft, and the through hole position that connects in the front and back of knife sharpener body installs and fixes handgrip; Handgrip is the principal organ of lever; Leverage by handgrip is formed is realized the driving to speed changer, above the knife sharpener body under two emery wheels, drawer is installed so that accept or remove the dust that is produced when whetting a knife.
Beneficial effect: the present invention is owing to use hand to start handle, and the reciprocating motion of handgrip converts speed changer to and rotatablely moves, and speed changer drives power transmission shaft and rotates; Rotate thereby drive emery wheel, so, kitchen knife is put between two formed v-notch of emery wheel; Just can reach the purpose of tempering kitchen knife; The present invention not only has the kitchen knife of tempering efficient advantage of higher, simultaneously, has the kitchen knife of tempering effect advantage preferably.
Description of drawings
Below in conjunction with accompanying drawing structure of the present invention is described further;
Fig. 1 is a structure principle chart of the present invention;
Shown in the figure: 1, knife sharpener body; 2, handgrip; 3, speed changer; 4, power transmission shaft; 5, bearing; 6, nut; 7, spring; 8, feather key; 9, positioning sleeve; 10, emery wheel; 11, drawer; 12, through hole.
The specific embodiment
