Abstract
The utility model discloses a kind of environmentally friendly stationary knifes, including environmentally friendly stationary knife ontology, environmentally friendly stationary knife ontology is made of knife wall and blade, the top of knife wall is fixed with the blade being linked together, the top of blade equidistantly offers several trapezoidal rack gears, and the groove for being opened in blade top is equipped between two trapezoidal rack gears, the middle part of several trapezoidal rack gears offers through-hole.A kind of environmentally friendly stationary knife of the utility model, the through-hole opened up by trapezoidal rack surface increase the service life of environmentally friendly stationary knife ontology convenient for the heat dissipation of trapezoidal rack gear in use；The chamfering being equipped with by knife wall bottom end two sides reduces the stress of knife wall.
Description
Technical field
The utility model relates to a kind of knife, in particular to a kind of environmentally friendly stationary knife.
Background technique
Knife is the short weapon of the long sword of single side.Refer to the tool can be used for cutting, cut, cutting, chopping, piercing simultaneously, is collectively referred to as also with dagger
For food cooking device.The initial form of knife, it is very close with battle-axe used in ancient China.Its shape is short handle, is raised one's head and looked, for knife ridge without decorations, blade is longer.To spring and autumn
Great variety occurs for the Warring States Period, the shape of knife, when the Two Hans, knife gradually develop be infantry one of weapons of advocating war, occur simultaneously
Many various forms of long-hilt bread-swords；Copper tool deposits that generation quantity is few, and the bodily form is frivolous, and only 0.35 centimetre of thickness, shape is thick
Point there is raise one's head and look knife, long Weapon-handle-of-bamboo-strips volume first knife, flat blade cutter, song angle of throat etc. of short handle several classes of.
During the work time, heat dissipation effect is poor, influences the service life of stationary knife, results in the need for frequently for existing environmental protection stationary knife
More allowing blade replacement, it is therefore desirable to equipped with it is a kind of convenient for radiate and high rigidity stationary knife.
Utility model content
The purpose of this utility model is to provide a kind of environmentally friendly stationary knifes, fixed to solve environmental protection mentioned above in the background art
The problem of during the work time, heat dissipation effect is poor for knife, influences the service life of stationary knife, results in the need for frequent more allowing blade replacement.
To achieve the above object, the utility model provides the following technical solutions: a kind of environmental protection stationary knife, including environmentally friendly stationary knife sheet
Body, the environmental protection stationary knife ontology are made of knife wall and blade, and the top of the knife wall is fixed with the blade being linked together, described
The top of blade equidistantly offers several trapezoidal rack gears, and is equipped between two trapezoidal rack gears and is opened in the recessed of blade top
The middle part of slot, several trapezoidal rack gears offers through-hole.
As a kind of optimal technical scheme of the utility model, the height of the knife wall is 71.91mm ± 0.05mm, length
For 300mm ± 0.03mm, width is 34.97mm ± 0.03mm.
As a kind of optimal technical scheme of the utility model, internal diameter 18mm ± 0.01mm of the through-hole.
As a kind of optimal technical scheme of the utility model, the two sides of knife wall bottom end are fixed with chamfering.
As a kind of optimal technical scheme of the utility model, the environmental protection stationary knife ontology is made of 50# steel material.
Compared with prior art, the utility model has the beneficial effects that a kind of environmentally friendly stationary knife of the utility model, by trapezoidal
The through-hole that rack surface opens up increases the service life of environmentally friendly stationary knife ontology convenient for the heat dissipation of trapezoidal rack gear in use；
The chamfering being equipped with by knife wall bottom end two sides reduces the stress of knife wall.
Detailed description of the invention
FIG. 1 is a schematic structural view of the utility model；
Fig. 2 is the schematic diagram of the section structure of the utility model.
In figure: 1, environmentally friendly stationary knife ontology；2, knife wall；3, blade；4, trapezoidal rack gear；5, through-hole；6, groove；7, chamfering.
Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work
Every other embodiment obtained, fall within the protection scope of the utility model.
The utility model provides a kind of environmentally friendly stationary knife, including environmentally friendly stationary knife ontology 1, environmentally friendly stationary knife sheet referring to FIG. 1-2,
Body 1 is made of knife wall 2 and blade 3, and the top of knife wall 2 is fixed with the blade 3 being linked together, and the top of blade 3 equidistantly opens up
There are several trapezoidal rack gears 4, and is equipped with the groove 6 for being opened in 3 top of blade, several stepped tooths between two trapezoidal rack gears 4
The middle part of item 4 offers through-hole 5.
Preferably, the height of knife wall 2 is 71.91mm ± 0.05mm, and length is 300mm ± 0.03mm, width 34.97mm
