The utility model adopts the technical proposal that: the utility model provides a single-edged blade of cutting injury prevention, includes the blade body, still includes the protection casing, the blade body constitute by blade portion and the cutting edge portion that is located blade portion one side, the both sides of blade portion are equipped with the shaft hole, the protection casing includes cutting part backplate, back backplate and two stabilizer blades, the side of cutting part backplate is connected perpendicularly with the side of back backplate, the one end of stabilizer blade is passed through the pivot rotatable coupling on the stabilizer blade in the shaft hole, and other end fixed connection is on cutting part backplate and back backplate, be equipped with protruding muscle on the cutting part backplate.
Furthermore, the section of the knife body part is of a rectangular structure, and one side of the knife body part is gradually thinned to form the knife edge part.
Furthermore, a long groove is arranged on the back guard plate.
Furthermore, the height of the convex rib is 1-3 mm.
Furthermore, the top of the convex rib is in arc transition.
Furthermore, the outer surface of the blade body is also provided with a wear-resistant layer.
Further, the thickness of the wear-resistant layer is 20nm-100 nm.
The utility model has the advantages that: the utility model discloses an increase the protection casing on the blade, can cover the cutting edge portion of blade, can use the protection casing for the point of gripping in the time of taking, avoid the blade to cut skin, play fine cut resistance ability, have the effect of protection cutting edge portion simultaneously concurrently.
In addition to the objects, features and advantages described above, other objects, features and advantages of the present invention are also provided.
The present invention will be described in further detail below with reference to the drawings.
Drawings
Fig. 1 is a schematic structural diagram of the present invention.
Fig. 2 is a schematic structural view of the shield.
Fig. 3 is a side schematic view of a blade body.
In the figure: 1. a blade body; 2. a protective cover; 3. a blade body portion; 4. a knife edge part; 5. a shaft hole; 6. protecting the blade part; 7. a back guard plate; 8. a support leg; 9. a rotating shaft; 10. a rib is protruded; 11. a long groove.
Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.
It should be noted that, if directional indications (such as upper, lower, left, right, front and rear … …) are involved in the embodiment of the present invention, the directional indications are only used to explain the relative position relationship between the components, the motion situation, etc. in a specific posture (as shown in the drawings), and if the specific posture is changed, the directional indications are changed accordingly.
The utility model provides a cut-preventing single-edge blade.
In this embodiment, refer to fig. 1 to 3, this single-edge blade of anti-cutting wound, including blade body 1, still include protection casing 2, blade body 1 constitute by blade portion 3 and the cutting edge portion 4 that is located blade portion one side, the both sides of blade portion 3 are equipped with shaft hole 5, protection casing 2 includes cutting part backplate 6, back backplate 7 and two stabilizer blades 8, the side of cutting part backplate is connected perpendicularly with the side of back backplate, pivot 9 rotatable coupling on the stabilizer blade is passed through to the one end of stabilizer blade 8 is on shaft hole 5, other end fixed connection is on cutting part backplate and back backplate, be equipped with protruding muscle 10 on the cutting part backplate.
Among the above-mentioned technical scheme, the protection casing can adopt metal or plastics to make, and on the stabilizer blade passed through pivot swivelling joint blade body on the stabilizer blade, when taking, can use the protection casing for holding the point to avoid sword body fish tail skin, have fine anti-cutting wound effect. In addition, the protective cover and the blade are of a detachable structure, and when the protective cover is detached, the supporting legs of the protective cover are separated towards two sides. In addition, after the blade is used up, the blade can be installed back into the protective cover, and the protective cover can prevent the blade from contacting with an external object, so that the blade is protected. Wherein the convex rib plays limiting displacement, avoids the cutting edge to rotate out from the protection casing.
Specifically, the cross section of the blade part is of a rectangular structure, and one side of the blade part becomes thinner gradually to form the blade part. As shown in fig. 3, the blade portion is thick relative to the blade portion, and the machining position of the shaft hole is secured.
Specifically, the back guard plate is provided with a long groove; the long groove can be used for fingers to penetrate through to push out the blade, and meanwhile, the effect of saving raw materials can be achieved.
The height of the convex rib is 1-3 mm; the top of the convex rib is in arc transition; the outer surface of the blade body is also provided with a wear-resistant layer; the thickness of the wear-resistant layer is 20nm-100 nm. Through setting up the wearing layer, improve the wear resistance of blade, improve life.
The utility model discloses an increase the protection casing on the blade, can cover the cutting edge portion of blade, can use the protection casing for the point of gripping in the time of taking, avoid the blade to cut skin, play fine cut resistance ability, have the effect of protection cutting edge portion simultaneously concurrently.
The skilled person should understand that: although the present invention has been described in terms of the above embodiments, the inventive concepts are not limited to the embodiments, and any modifications that utilize the inventive concepts are intended to be included within the scope of the appended claims.
